  • The
    WPI’s response to CROI
    was

    “It is interesting that infectious XMRV is
    still found only in human cells and not in mouse cells or mice. In addition,
    these data have little to say about XMRV infection in humans.” In an email Dr.
    Mikovits stated “There is still not one piece of evidence of contamination in
    the Science paper. All of the authors stand by the conclusions and data in
    Lombardi et al”.

    Dr.
    Deckoff-Jones Talks
    – Dr. Mikovits was too busy to do an interview
    but Dr. Deckoff-Jones got her two cents in her personal blog. She
    asserted that because neither the WPI nor the Cleveland or the NCI labs  in the
    study have ever used the 22RV1 cell line their samples could not have been
    contaminated by it. Indeed she reported that that “all three investigators at
    different institutions can prove beyond a shadow of a doubt (that it – 22RV1
    cell line) never entered their laboratories (personal communication)”.

    Actually proving contamination has occurred
    has always been the weak link in the contamination theorists logic chain. Thus
    far the WPI has used none of the reagents, cell line, laboratory animals, etc.
    that have been associated with contamination.

    This is an interesting point given that the
    central problem with XMRV has not been that it’s found too often -as one might
    suspect if it was a lab escape – but that
    it’s not been found enough
    . If XMRV is an escape from a lab why is it
    showing up in a lab that seems to have so few links to possible sources of
    contamination? Conversely, why is XMRV not showing up in other labs more
    often? To date only the labs in the original study (and
    VIP Dx) have been the only labs to find XMRV.

    Garson and Tower’s analysis of Silverman’s
    integration data suggested that Silverman’s prostate cancer samples may have
    been contaminated but that data was inferential and we will surely hear more
    from Silverman on that. Even if that’s so how did the virus get into Silverman’s
    lab if it has not been using 22RVI and why has it not appeared elsewhere?

    She also noted that inadvertent endogenous
    retrovirus introduction into cell cultures and vaccines is nothing new and that
    mouse cells have been used frequently in these processes and in gene therapy.
    Essentially she seems to be saying XMRV…..a lab creation? Sure -why not? But why
    assume that it took until 1999 for a recombinant event to create XMRV? Why not
    much, much earlier?

    She ends by suggesting that many
    other recombinant retroviruses are possibly infecting humans around the world by
    the same process and that it’s quite plausible that vaccines containing
    infectious human retroviruses have going out for over 50 years. She then ties De
    Freitas retrovirus in CFS to autism and suggests the CDC’s inability to
    find it in 1993 may have caused the current epidemic of autism.

  • Dr. Vernon on CROI - Dr. Vernon presented a step by step overview of the CROI papers. She ended up concluding that
    the issues surrounding XMRV continued to grow rather than being resolved after the conference. She agreed the
    “current evidence’ suggest that XMRV was created in the lab but that doesn’t mean the virus is
    benign or is not associated with diseases and XMRV should continue to be the focus of study – and indeed
    the conference presenters indicated it would be. Her endpoints are below. 

    I agree that standardized, validated assays must be a priority for the field.
    The discussion about ways in which XMRV behaves differently than other gammaretroviruses and
    its ability to establish productive infection highlight the need for
    continued disease association research. The list of important outstanding issues grew longer,
    rather than shorter, after hearing these presentations. Even though the evidence indicates
    XMRV evolved in a lab, that doesn’t imply that its current existence is benign.Darwin did not have the advantage of understanding how viruses contribute to the evolution
    and adaptation of species. We now know that viruses are some of the most rapidly evolving
    “species” on the planet. This seems to be a prime opportunity for scientists to put fractious
    politics aside, consider all the facts and keep an open mind before concluding that there are
    no diseases associated with XMRV.”

  • Dr. Mikovits - reportedly penned an email to someone stating something to the effect that “we will prove XMRV is not
    a contaminant”. An interview with her on the current state of XMR has been requested.
  • Autism Study – Negative.
    This study has been ‘out’ for awhile but just showed up in Pubmed. No XMRV was found in the blood, semen or
    brains of about 100 people with Austism. The autism link to XMRV was announced early but this is the second study that has failed to find it
    in people with autism. Alex on the PR Forums pointed out that the WPI looked at autistic individuals living in families where members had already
    tested positive for XMRV  and this study simply looked at people with autism
    and they could be different cohorts. . (This could suggest XMRV could be present in some people with autism but not contribute to
    autism in most people)
  • XMRV Study Review - a review of published studies and past conference reports (as memory serves!) of disease groups looked at since the Science paper was published in Oct of 2009 presents a fairly bleak picture.
    Of CFS studes 4 or 6 have been positive (depending on whether Alter/Lo’s/Hansen’s paper is put into the XMRV or MLV category) and 9 studies
    have been negative. In prostate cancer we have two positives and 6 negatives (some of the negatives had extremely low
    positive rates), HIV – 0 positive, 5 negative, Autism – 0 positive, 2 negative; Fibromyalgia – 0 positive and 2 negative,
    immune compromised – 0 positive and 2 negative and multiple sclerosis/
    /infectious diseases/arthritis – all 0 positive and 1 negative. (Since some studies
    looked at multiple groups this overstates the number of studies.

  • Come Down At CROI -
    XMRV took its biggest shots yet the CROI retrovirology
    conference. Researchers have been working their way a line of investigation that
    culminated in a paper by Dr. Cingoz that purports that XMRV is a laboratory
    derived virus that was accidentally created between 1996 and 1999 when prostate
    cancer cells were grafted onto nude mice. Two  endogenous retroviruses in the
    nude mice have been identified that are believed to have ‘recombined’ to form
    the complete XMRV virus. From  there the thinking is apparently that XMRV
    spread  from lab to lab and somehow found it’s way into the WPI’s samples XMRV  is a live virus that
    can readily infect tissues in the lab but it’s fate as a human infectious
    pathogen is unclear. 

    The evidence is still circumstantial and
    there’s no direct evidence proving contamination of the WPI’s samples. Instead
    there’s a logical  and a
    short comment reportedly from Dr. Mikovits clearly indicated she was not buying
    it, but the prevailing
    opinion, at least at this conference, was clearly that XMRV found its way
    (somehow) into the WPI’s and others samples and never actually infected the
    patients. It appears that our perennial fence-sitter. Dr. Coffin is not sitting
    on the fence anymore. His lab has been heavily involved in digging into the
    contamination issue and with the latest study seemingly putting all the pieces
    together, he appears to be satisfied with the majority opinion.

    More News – Spain was well
    represented with three papers. One group found no XMRV in HIV patients, another
    looked at over 1100 CFS, FM, HIV, hepatitis and other patients and found 0%
    antibodies (Abbott) or or positive PCR  resultsfrom the CFS patients. They
    did find 6% positive results from the cancer
    patients but only from one gene and no antibody tests were positive.The
    irsiCaixa lab many had pinned their hopes on did find XMRV growing in a small
    number of EBV transformed cell lines, which was something, but the current focus
    on contamination in cell lines the effect of that finding was blunted. p Dr.
    Mikovits has questioned whether the IAP contamination test might falsely identify XMRV as a contaminant
    but that did not happen in the B-cell study; the IAP test showed no contaminants
    in the positive B-cell lines.

    A German lab found no XMRV in 500 samples from transplant patients.

    The Positive Patient ReTest Tests-
    As they concentrate their efforts to find XMRV researchers are now looking in
    patient that tested positive in the past – presumably by the WPI. Dr. Joliceur,
    Dr. Miller and Dr. Maldarelli have all at least started studies employing this
    kind of protocol. At the conference we heard of two more small efforts. (Of
    course this appears to be the central protocol of the BWG study; it involves
    getting a fairly large number of patients that tested positive for XMRV by the
    WPI, throwing in a number of certified negative controls and then determining if
    the WPI and the other labs can pick out the patients identified as having an
    XMRV infection.)

    New Test – Same Result
    - The NCI funded Kearny study (with Malderelli and Coffin and the Blood XMRV Sci
    Res Working Group) reported they have developed a ‘single copy’ assay (X-SCA)
    that can differentiate between XMRV and MLV’s. Dr. Kearny warned that simply
    cutting 300 nucleotides from the end of one of the sequences would result in
    researchers misidentifying a MLV (mouse contaminant) as XMRV.  Importantly
    they validated their test using the macaques  infected with XMRV. She
    demonstrated that the X-SCA test was able to pick up the virus in immune blood
    cells of the macaques throughout their (admittedly brief) lifespan.  When she
    turned to four patient previously identified as having XMRV, however, she was
    unable to find XMRV. She also tested 134 patients with prostate cancer  and
    found no XMRV.

    Henrich had not been able to find XMRV in CFS and in
    other patients with immune dysregulation in the big Mass study. Now he looked for XMRV in two previously positive patients and
    did find an MLV sequence that was 90% similar to that found in the Alter/Lo
    trial but concluded it was a contaminant.

    Missing Advocates  – Some of XMRV’s chief advocates (Dr. Mikovits, Dr. Ruscetti, Dr.
    Silverman, Dr. Singh, Dr. Alter, Dr. Lo) who would have presented a different
    viewpoint did not present at the conference. We’re also, of course, still waiting
    on studies from Dr. Lipkin, Glaxo-Smith Kline and Dr. Singh and of course, the
    all important Blood Working Group tests. It’s hard to imagine that the
    double-blinded BWG tests will not either turn the field around for XMRV or
    essentially end it. If the WPI can pick out the positive samples from the
    negative samples; ie show that the bug is there and they can find – then one
    imagines the research community will come roaring back.


    Tomorrow, the key culprit at CROI
    - the 22RVI cell line and why it’s
    playing such a big role plus the CDC finds XMRV….. in its lab workers? and
    more.

Feb 27th

  • CROI is Here!
    - the big Retrovirology Conference CROI has begun and we have the entire lineup and (contrary to past
    reports) it has a full XMRV slate. The XMRV presentations will take place on March 2nd, the last day of the Conference. 

    They cover a variety of aspects; researchers continue to refine their ability to
    find the virus with one study focusing on a new cell line developed to detect it
    and the development of a new assay by NCI researcher Mary Kearny. The irsiCaixa
    lab in Spain that appeared to have found the virus appear to indicate they can
    infect lymphoid cells with it and that they have found B-cells infected with
    XMRV. The later study would be the more important one since if my interpretation
    of the title is correct, it could
    indicate they found it in blood samples.

    The meaning of Henrich’s talk
    “Discordant XMRV Test Results and Non-reproducible Mouse Endogenous Retroviral Detection in an XMRV Prevalence Study” – is definitely
    is anybody’s guess. He did the Harvard study last year that failed to find
    XMRV in several hundred HIV, rheumatoid arthritis and CFS patients. Dr. Switzer of the CDC will
    apparently talk on the CDC/Cooperative Diagnostic study that failed to find XMRV using a variety of PCR
    and antibody tests in CFS patients across the country. Interestingly, he will also give a talk on
    ‘Extensive Genetic Recombination in the XMRV Genome” Genetic recombination occurs when genes in paired
    chromosomes switch places. His talk certainly indicates researchers continue to dive deep in XMRV.

    Hue, the geneticist, who found that the XMRV believed found in humans was basically identical to a strain produced in the lab
    by the 22RV1 cell line, will
    report that XMRV is caused by laboratory contamination. Since Hue’s paper appeared some time ago it appears
    he has some new information to report. The last talk will assert that XMRV came from an endogenous
    murine leukemia retrovirus, which would be interesting, but would not, I wouldn’t think mean anything about
    XMRV’s provenance in humans. My guess is that it doesn’t matter where XMRV ultimately came
    from – what matters is where the XMRV in the blood samples and prostate samples of humans came from. If they came from an
    infected human cell then XMRV is in good shape, if they came from the 22RV1 cell line
    -as Hue asserts – then XMRV is
    in real trouble.

    This is why the issue of XMRV integration has become so important. An integration study that
    indicated XMRV DNA was surrouned by human DNA would indicate that infection had occurred. One that indicated
    that XMRV DNA was surrounded by say, mouse DNA would indicate otherwise. A
    recent study suggested XMRV was not integrated into human DNA but it was not
    definitive. Dr. Silverman, one of the co-authors of the Science paper,  is
    reportedly looking at XMRV integration. A report on the Forums from someone who
    says he has an inside source states Dr. Silverman is not finding XMRV
    integration into human cells but Dr. Silverman is not at this point scheduled to
    speak at the conference – so that is decidedly anecdotal information.

  • Dr. Mikovits to Talk - Dr.
    Mikovits will talk on March 17th at the University of Alberta  in the new
    La Ka Shing Institute of Virology on “Strategies for Detecting XMRV in
    Clinical Samples”
    . This is an interesting location to hold this talk
    because the Univ. of Alberta reported in early summer of last year they were
    collaborating with the WPI to look for XMRV in CFS patients. They anticipated
    they would be done in a couple of months – and that was the last time we heard
    of them. Now Dr. Mikovits is talking on how to find XMRV there. Have Univ of
    Alberta researchers found the virus?

Feb 25th

  • Two More Negative Studies – it’s almost beginning to sound like a broken record but two more negative
    studies have come out.
    A Cooperative Diagnostics/CDC study came out that used severely ill CFS
    patients from across the country and multiple PCR tests, including those used by the Lombardi group, which were
    more sensitive than ever plus antibody tests prepared using the ‘wild virus’ which worked perfectly in the
    infected macaques….and found nothing at all in the CFS patients.  An
    interview iwth the author is in the works. 

    Another study from the

    Wellcome Trust Group
    that did the genetic analysis of XMRV in the Hue paper
    indirectly suggested that the prostate cancer studies  are from a
    contaminant. They didn’t provide proof but their findings suggested that might
    be so.


  • The PCR Question!
    - there’s a really good article in BioTechniques.com on
    the role PCR  should or should not play play in figuring out XMRV and
    appears to cover all sides of the issue. It shows how tricky everything is…it
    mentions the great lengths the WPI went to ensure that no contamination occurred
    but then notes that with such rare viruses researchers have to increase their
    PCR sensitivity which makes them more susceptible to mouse DNA contamination. On
    the other hand Dr. Mikovits referred to the extensive tests on controls that
    have not shown contamination in them but have shown evidence of the virus in
    patients. Another researcher said you have to overthrow an entire field of
    Science if you were not to trust the PCR results. There is still no easy answer.
    The article is called “Walking on Eggshells, PCR assays for XMRV detection”.

  • People with CFS Locked out of Alter/Lo Videocast

- Without warning or
explanation the NIH decided to allow only people associated with the NIH to
watch the Alter/Lo videocast on “Is there a Virus in CFS” disappointing many
people who had planned their day around it. My understanding was that the event
was open to all. On Jan 26th the CAA
reported that the videocast was free and open to the public and no registration
was required as well. Clicking on the link today, however, brought a title
stating (NIH Only) which meant that only computers in the NIH network or with a
special PIN could view it. 116 people were watching the videocast shortly after
it started.

According to the FAQ’s the program should be archived in a few days and then presumably
will be available to all. The NIH has a YouTube site where about 50 video’s are currently posted.

  • XMRV in New Zealand – there don’t appear to be any XMRV studies in New Zealand but
    they are preparing the ground. ANZMES has provided Dr. Warren Tate, the Associate Dean of
    Research at the Universit of Otago, with the funds to collect and catalogue
    blood samples (ie create their own Biobank). Once the validated assays are
    present they hope to look for immune biomarkers as well and they can use the blood samples to quickly attempt to validate significant
    research findings as they arise. They are building a foundation for success :) . (Thanks to Heather
    for the info) From Doctor Tate: 

    I thought the
    research paper published in Science was exquisite. Left open was a
    major question however; was this an opportunistic virus that had
    colonised a defective immune system perhaps sustaining an illness
    initiated by another cause (virus or different microbe, or
    environmental toxin), or was it the primary cause of the illness?
    Scientists are in heated debate about this today-the answer is that we
    just do not know at present.Although several groups in the United Kingdom and Europe, as well as the Centre
    for Disease Control (CDC) in the US reported they could not find XMRV in patient
    cohorts, in the last 2-3 months there have been several new reports of the virus
    having been found CFS patient samples in both US and Europe. Nancy Klimas
    indicated in her recent visit to New Zealand that the different research groups
    are finally talking with each other and consensus techniques for collecting
    blood samples, and for detecting the virus will emerge soon.

    How can those affected with ME/CFS here in New Zealand benefit from
    this? At present we do not have a carefully catalogued sample
    collection from patients that is suitable for comprehensive study, not
    only to screen for XMRV, but also for analysing DNA polymorphisms
    (specific variations), for doing gene screens, and for studying
    defective proteins.

    ANZMES has provided the support to me to establish
    this, for which I am very grateful. That in my view is the first
    essential step, but must be done carefully so the bloods have validity
    for a predicted wide range of future studies. My research group is
    developing molecular tools that might be suitable for a set of
    diagnostic biomarkers focussing on molecular changes in ME/CFS in the
    innate immune pathway against viruses. We hope to access the tools for
    screening for XMRV when the blood sampling and detection consensus is
    settled. It is my goal that we can have a research and patient based
    focus for ME/CFS in New Zealand that can rapidly respond to new
    international findings as they arise.”

  • Alter/Lo Videocast
    is tomorrow
    - This 2 hour (!) live
    videocast from two of the most forefront proponents of XMRV could be really

  • “A Persistent Chronic Infection” -
    in Amy Dockser Marcus’s latest blog on the Macaque study she quotes Dr. Silverman as saying
    its clear that “The virus causes chronic, persistent infection” and notes that the study clearly shows the virus
    can be difficult to find in the blood – even after its taken root in numerous organs of the body. They also noted that
    Abbott labs funded the study (at $50,000 an animal) as part of its effort to develop (antibody) tests for XMRV. The publication of
    the Macaque study has been a nice win for XMRV after some tough times. It doesn’t explain why
    other labs have been unable to find XMRV when the WPI was (patient cohort?) but it does clearly indicate how hard it can be to find the virus in the
    blood even when it’s present in numerous organs. Check out the Racaniello blog below for more.
  • Dr. Raccaniello Takes A Look at the Recent Macaque Study
    Published
    - among other things he noted the wide variety of tissues
    effected including spleen, lymph nodes, the lining of the gastrointestinal
    tract, prostate, testis, cervix, vagina, and pancreas, but not in others
    including brain, heart, kidney, and bladder and that XMRV showed up in the
    prostate early. The concentration of XMRV in the reproductive tissues (testis,
    cervix, vagina)  suggests it may be transmitted sexually. He noted that the
    virus levels plummet after the acute infection but that immunocompromised
    individuals  may show a different pattern (increased levels of virus?). He also
    noted that the authors stated that if XMRV causes CFS or prostate cancer the
    link would be a ‘temporally distant one” which just seems to suggest that it
    looks like it would take a substantial amount of time to do its mischief.  He stated that in
    interpreting the results of animal studies, we must keep in mind the adage, ‘Mice lie, monkeys exaggerate‘. We also learned that each
    monkey costs $50,000!

    Question session - the questions were the most interesting
    part of the blog.
    In response to a question about looking for XMRV in human tissues he felt that the study should prompt
    research  into that: this
    work should stimulate research into understanding where XMRV can be found in humans”. One interesting question notes that the
    investigators were able to ‘re-activate the virus by stimulating the virus and
    asks why not do that in humans? Or why not simply have people with CFS exercise
    and see what happens?Look in the organs – Dr. Raccaniello clearly felt the study explained why XMRV
    might be so difficult to detect in humans and thought researchers should start
    looking in the organs. “You are right, from the results of this study it is
    clear that we should be looking for XMRV in other organs, rather than blood. As the authors
    write, if XMRV is involved in CFS and PC, the infection probably occurred some
    time before disease. And the findings do suggest why the virus is difficult to
    detect in the blood. Even proviral DNA was not detected, although in at least
    one monkey it was still present.

    No need to kill cells to cause damage - to a question of how XMRV could cause damage if it’s not killing cells
    Dr. Racaniello replied – actually there are a number of ways: “Many viruses are noncytopathic in cell culture, yet cause disease in
    humans. The tissue/organ damage is believed to be a consequence of
    immunopathology – the immune response damages cells and tissues. There
    is experimental support for this mechanism of pathogenesis for a
    number of human viral diseases. See
    http://www.virology.ws/2009/01…/.

  • Spanish XMRV Researchers to Speak at
    CROI
    - The Irsi Caixa team that appeared to be able to find XMRV last year
    are reported to be giving a presentation with the intriguing title “XMRV:
    New Findings and Controversies” at the big CROI Conference
    (Conference on Retroviruses and Opportunistic Infections) in Boston from just a
    week from now (Feb 27th-March 2nd). CROI did videotape all their presentations
    last year.

    These conferences will probably be good indication of
    current interest in XMRV as researchers often present the results of
    ongoing studies in them. It’ll be interesting, as we go through the year, to see how
    much XMRV shows up at the conferences one year later. In early 2010 XMRV was a pretty hot item; just
    a couple months after the release of the paper there were seven XMRV presentations
    including one plenary session at CROI. In 2011 XMRV has one presentation and one
    abstract devoted to it (that I could find :) )

  • Spanish FM XMRV Study – zero results. What to say except that this is another zero result study. This was not the
    Spanish group, however, that reported they had found XMRV earlier.
  • Dr. Mikovits on looking for a Human Tissue XMRV Reservoir
    - Mya Simmons asked
    Dr. Mikovits about exploring a human tissue for XMRV. Dr. Mikovits replied that
    yes, they are interested in doing that but that a ‘political climate’ devoted to denying  XMRV’s existence in humans was making
    getting that done difficult. 

    “It has been detected in the prostate and in the monkey studies in ovaries,
    spleen lymph nodes and kidneys. More extensive types of such studies are being planned by the WPI which is applying for human assurance protocol to create a tissue repository to do just that. The difficulty in doing such studies is the political climate trying to deny that XMRV, a new human retrovirus of unknown
    pathogenic potential, is circulating through the human population.”

  • Dr. Deckoff-Jones Talks

- The XMRV finding has put the spotlight for the past year on the research side of the WPI (or the Center for Neuro-immune Disease) but that’s just half of the equation. When the Clinical side of the Center opens sometime in May
it will bring an entire new entity to the ME/CFS Community…an integrated clinic/research facility.

In this interview Dr. Deckoff-Jones talks about other the side of the WPI – the Clinic side. We find
out how large it is (it’s quite large!), what they hope to accomplish (quite a bit), how they plan to do it and how she hopes
it will change the face of CFS treatment.

  • Dr. McClure Resigns from CFS Grant Review Panel
    - The CFS SEP or Dr. McClure
    or someone was apparently unprepared for the strong response from the patient
    community as she stepped down from the post on Sunday. One wonders how often, if
    ever, patient activity has prompted a change in membership in a grant review
    panel for the NIH. (One wonders how many patient groups (a) know of grant review
    panels and/or (b) actually take action to try to remove members. In any case,
    Dr. McClure is gone and her replacement has not been, to my knowledge, announced
    yet.

    • Malderelli Study - the Malderelli XMRV retest study has elicited a
      ‘little’ controversy…:). Dr. Malderelli,
      in a discussion with a patient, said he was collaborating with the WPI. Dr. Mikovits, however, in several emails
      posted on the internet, has said neither the WPI nor Drs. Alter/Lo are or ever have collaborated with Dr. Malderelli.
      Dr. Mikovits also wants patients to know that the Malderilli study will take
      place in Dr. Coffin’s lab. From an email to a patient “She also informed me that the retesting of XMRV positive people is
      set to take place in John Coffin’ s laboratory and that Dr. Malderalli works for John Coffin.”
       

      IAP Test - there was quite a push to have researchers employ the
      IAP test in their studies after the Retrovirology papers came out. The
      controversy over what type of contamination test makes one wonder what, if
      anything, researchers in this field can agree on. It’s almost one thing after
      another (XMRV vs XMLV’s, VP62 vs wild type, contamination test, PCR vs
      culturing, freezing/refreezing samples, test tube types, patient cohorts,….).
      At the Workshop both sides (pro mtDNA, pro IAP) somehow not only proclaimed that
      their test was more sensitive but that it was much more sensitive.

      One thing is very clear, though, Dr. Mikovits does not support using the IAP test
      in XMRV retest studies, eg; “The WPI will not recommend any XMRV positive patient participate in any study that uses the IAP assay ..it is not validated..never has been.”

      Of course, the offsetting problem is that these other researchers don’t trust
      the mtDNA test!…So now not only is there no consensus on how to find XMRV;
      there’s no consensus on how to test for contamination…..

      Dr. Mikovits has laid out her concerns in this area. Earlier she pointed to the paper and
      presentation that concerned her. The ball, now, is really in the other researchers court;
      it’s time for them to respond
      to her concerns. Hopefully they will do so publically.

    • Alter/Lo Videocast in About Two Weeks
      - keep this on the calendar. Except for the Miller/Malderilli
      controversy the XMRV beat has been pretty dead lately but this 2 hour (!) live
      videocast from two of the most forefront proponents of XMRV could be really
      something.  Dr’s. Alter and Lo will be talking on Is There a Virus
      in CFS?
      on Feb 22nd.
      Check it out here.
    • Indy Star Article on CFS and XMRV nice article on CFS and XMRV. Dr. Bells notes that if XMRV is it in
      CFS–we’ve got it licked…which may not be, at least in the long term, too optimistic given the success seen with HIV – a much more complex retrovirus.

    • NIH ME/CFS Grant Review Panel (CFS SEP) Takes a Step Back

    - this is probably old news for many but
    the seating of the Feb grant review panel for CFS at the NIH drew
    no cheers. Yes, there were more researchers with CFS experience than on most of the
    CFS SEP’s but that’s not saying much. Pain researchers dominated the panel (twice as many as
    CFS) and we lost some strong pro CFS voices (Klimas, Ruscetti, Broderick). What
    really got everyones attention,  though, was the presence of
    Dr. McClure – who has been very clear that she believes XMRV does not exist. She is one of the
    two retrovirologists on the panel which means she will be reviewing any XMRV grant applications….not a pretty picture.
    Protests quickly sprung up;
    check out more on this situation here.

  • Spinal Fluid VIP Dx Study Finds No XMRV (or anything else)
    - This US NAIAD study
    used VIP Dx Labs to look for XMRV in blinded CSF samples using both straight PCR
    and culture. It failed to find XMRV using. 

    This was quite a promising study and it’s
    the second NIH funded study in the last month to use cutting edge technology to
    take a broad search for pathogens in the blood or spinal fluid that came up zip.

    Their hope was
    that

    The discovery of potential pathogens in cerebrospinal fluid of CFS would be
    field-altering in terms of approach to the study of the disease and possible
    early detection, prevention and treatment. This could be the gateway step to
    generate new hypotheses and begin investigation into a microbe’s causal
    association and ways to prevent (egg vaccine) or counteract the effects of a
    microbial pathogen”

    It was an enticing vision but it was not to
    be. Bear in mind that it was cutting edge technology and that can cut both ways.

    • WPI Clinic Revealed
      - Dr. Deckoff-Jones, in her latest series blog, has been laying out how the Clinic is going to
      function..First the opening date for the
      WPI is looking like May – just four months from now. God bless her, she’s making the money side of the Clinic very clear. When was the
      last time any clinic spelled out why it was doing regarding money and treatment? She’s clearly very well versed in the how-to’s of clinic management. 

      First there’s the Medicare issue. The WPI just cannot
      afford to accept Medicare. (My experience is that very few CFS doctors accept insurance let alone Medicare). Medicare is apparently great for
      covering big operations and 20 minute visits but it sucks at covering 1 1/2 visits and complicated diseases.
      She said ” Also accepting Medicare/Medicaid is an all or nothing proposition. You have to play completely by their rules or opt out all together. They don’t allow a middle ground. The government thinks a 20 minute visit is adequate,
      particularly since there is no treatment.”

      No insurance - no insurance either and personally I would have been surprised if they had. The last ME/CFS doctor I saw that
      took insurance was about 20 years ago…it just doesn’t seem to be done anymore. The Clinic simply doesn’t have any money to
      burn through while they wait for insurance payments to kick in – it must start paying for itself immediately – or it won’t open – it’s as simple
      as that.

      Some Pro-bono Treatments - she did note that they will be providing pro bono treatments to a percentage of
      patients…(Some of our wealthier doctors could take a hint)..and they will determine the percentage as the clinic opens and as they
      figure out where they are financially. One has the feeling that Annette’s fingerprints are all over this…..it’s about helping
      as many people as possible given the monetary restraints of operating a medical clinic.

      Dr. Deckoff-Jones has been through the
      money grind at expensive, profit oriented clinics and stated
      I am determined not to do that to others. I hereby promise that nobody is going to get rich on the budget I’m putting together. Salaries will be fair, but we are looking for people for whom it is more than a job. The purpose of the clinic is to treat individual patients, but because of the translational medical approach that will be engendered by existing
      in concert with the research lab, there is a bigger purpose as well..
      . This was “I hereby promise that nobody is going to get rich on the budget I’m putting together.”
      was music to my ears. There certainly are many ME/CFS physicians who could be
      doing much better working outside of CFS – the work  is a labor of love for them as well and Dr. Bateman, who lost her sister to CFS, springs immediately
      to mind.

      The Clinic itself sounds very impressive. Alot of people will want to be seen – and it’s built to see alot of people.
      “As for whether the WPI should have a clinic that treats a volume of patients, or just be doing a few clinical trials, that decision has already been made. Annette Whittemore’s vision of translational medicine included treating patients from the beginning. Bench to bedside to bench. The clinic exists. It is a very large space, capable of seeing a large volume of patients.
      There are many patients asking to be seen.”

      The Director! - Dr. Deckoff-Jones will be the “Director of Clinical Services for
      the WPI” (actually called the Center for Neuro-immune Disease” and is recruiting
      Physicians, nurses, PA’s and a practice manager.

      What shines through in the blogs
      Dr. Deckoff-Jones posted is a commitment to
      communication and transparency. The WPI clinic will not be a miracle worker
      necessarily; what it will be able to do is systematically and methodically
      analyse the different treatments available and integrate them with cutting
      edge research. Nobody is doing anything but suggesting that there isn’t a long
      way to go but the WPI’s blend of integrated research/treatment should help move
      the field much faster. Would that there were more Centers out there. There’s
      alot more in these blogs. Check them
      out here.

    • GMCaF er GCmaF er GCMaf - whatever it is Dr. De Meirleir is using this immune factor extensively and several people
      have recently returned from his clinic to tell the tale…and it’s interesting to hear not just how they are doing -
      but Dr. DeMeirleir’s thoughts on treatment. Some people are improving and some are not. GCMaF is not an antiviral but it might
      be able to enable the body to better fight viruses. Check
      out the thread here and pick up some
      of the latest  information
      on how one of our most experienced physicians is using this new treatment – which is not available in the US.
    • Another Antiretroviral trial starts -pinkytuscadero has been bedridden for most of the past 24 years!!!! She has tried just about
      everything and nothing has really helped – a heart breaking story….Now she is starting out, under the care of her physician,
      with tenofovir and raltegavir (no AZT – her doctor thinks those two drugs are enough and AZT is harder on the body). Everybody wish
      her the best of luck… 

      On a interesting side note – at one point Ann mentioned
      that during a visit to an HIV doctor Dr. Mikovits statement that immune factors
      like Ampligen and GCMaF might actually stimulate XMRV to replicate and leave the cell. He said that’s exactly what they
      are trying to do with HIV! THey are trying activate HIV as much as possible so they can track it down and kill…
      HIV hides in its latent state and then later reactivates. If they can get it to reactivate all at once apparently they
      feel they have a chance of wiping it out completely – at least that’s the theory. They are nothing if not clever. :)

    • Improvement…
      - meanwhile Daffodil, who has been on ARV’s for a solid 10 months with
      little discernible improvement has had a much better last couple of weeks. Could
      it be that they are finally kicking in? She actually reduced her dose of AZT by a 100
      mgs…

    • NIH Videocast on Viruses and CFS Featuring Lo and Alter!

    - Now this will be interesting. Dr. Lo/Alter have presumably been
    working away for the last 3 months or so at either showing XMLV integration into human DNA in their samples or at isolating
    the virus itself. In about 3 1/2 weeks they’ll be giving a 2 hour lecture called “Demystifying
    CFS – Is there a Virus”. That’s a long lecture and who knows what come of it. This lecture will be
    technical – it’s directed towards Ph.D students and program managers but it’s open to everybody.

    • Arizona Lab Says Yes to XMRV?
      - JohnnyD on the PR Forums dug up a statement from diagnostic and research lab in
      Scottsdale, Arizona called Fry Labs – that yes, they are finding XMRV/XMLV’s. Fry appears to specialize in
      tick borne and other parasites and bacteria. XMRV appears to be the only virus, let alone retrovirus, they
      are looking for. 

      They present a nicely written, well documented paper altho their grammar isn’t too spectacular – check out this sentence in which
      two misspelled words in this sentence (provial instead of proviral, our instead of for)  “Fry Laboratories offers our research use PCR assay for licensed clinicians and health care professionals that
      specifically detects two different loci of these related provial genomes.

      They are sequencing everything they find and
      appear to be finding more XMLV’s than XMRV…and they appear to be finding them in levels similar to those Lot/Alter
      found in health controls; they state Any positive result from either region is followed up with direct sequencing and analysis.
      Fry Laboratories is in approximate agreement with an NIH study [23] where approximately 7.7% of
      an unselected population displaying detectable levels of murine leukemia viruses (MLV) related proviruses.
      We have sequenced fragments of these patient-derived genomes and have discovered novel variants of the XMRV and MLV-related viruses
      beyond what is published in the literature.”

      Some digging from a
      Forum

      found a blog
      which  has some questions about the lab and stated it is
      run by a single general practitioner who is not a board certified laboratory
      pathologist. There are definitely some warning signs; it’s a small lab – that is not
      experienced with retroviruses (or viruses) – that is finding new variants that
      other larger, more sophisticated and experienced labs have not been able to
      find…it’s something to be careful about.
      They are offering the XMRV test for physicians.


    • American Red Cross Moves Forward Quickly!
      – Amy Dockser’s latest health
      blog from the WSJ is really interesting. First of all it states that the Red
      Cross is starting to collect samples from no less than 10,000 donors to search
      for XMRV and XMLV’s. Another study will look at,120 people have already received
      blood. The tests will be run by Gen-Probe and Abbott labs. 

      Abbott, of course, is a huge diagnostic lab that has been
      developing antibody and presumably other tests for XMRV. They have been closely
      involved in XMRV for quite some time. They co-sponsored, with the NIH, the
      International Workshop on XMRV in Sept of last year and Dr. Silverman is a paid
      consultant to the lab. They were involved in the primate study that evoked so
      much interest but an earlier Abbot antibody study found almost no XMRV in
      about 1,000 healthy donors. Gen Probe on the other hand said in Nov that it had developed a
      super sensitive test that could pick up XMRV before antibodies to it were formed.

      Both studies are in the planning stages but sample collection will start soon.
      One wonders when testing will begin…It appears we’re at least 6 months from
      any BWG conclusions about standardized assays…Will Abbott be using the same
      antibody test they used before? (And why do another test when Abbott’s initial
      testing of about 1,000 samples was basically negative?) Will Gen Probe wait for the BWG findings??? Has the Red Cross -
      which also is not part of the BWG, decided that the Abbott and Gen Probe tests
      are accurate? It appears so.

    • Dr. Mikovits Talks – Part II - we now have two accounts of
      Dr. Mikovits talk.
      Lannie
      has finished up her account and
      Paula Carnes
      has provided her overview as well. As often happens both contain bits the
      other does not. Paula reported Dr. Mikovits said that 30% of adolescents
      who have tested positive for XMRV will go on to develop a severe case of infectious mononucleosis (glandular fever in some
      countries) and will not recover; ie will go on to develop CFS. Dr. Mikovits also reports that, while ARV’s have not been the
      silver bullet hoped for, that as patients on them do improve a bit – antibodies to XMRV start showing up – indicating that
      their immune functioning has improved. Most people on ARV’s, however, have not improved. If you’ve improved on Rich Van Konynenburg’s methylation protocol – you’ll probably
      be happy to see it recommended and others might want to give this pretty unexpensive option a try. 

      The WPI has found two
      variants of XMRV – one
      of which, if I got it right, is similar to the pMLV’s Alter found. Retesting has shown that about 30& of XMRV positive patients
      have both. The list of diseases XMRV has been found in has grown and grown and now includes FM, Lupus, Lyme disease (very
      strongly), peripheral neuropathy, autonomic neuropathy, some lymphomas, MS, Parkinson’s, ALS, dementia….This report appeared to
      come from a medical practice that is testing its ‘neuro-immune patients’ but apparently not others so there is no information on
      it prevalence in non neuro-immune disorders. The most exciting statement was Dr. Mikovits statement that with regard the second-guessing that
      she ‘expects the politics will go away shortly’ which suggests some big news might be in store in the near future.


    • GcMaF Results
      - iLannie reported that in her talk Dr. Mikovits noted that
      GcMaF- a  substance that is apparently not available in the US but which
      Dr. De Meirlier is using in his XMRV positive patients – might be able to get at
      XMRV reservoirs. Rivka is compiling a list of people on GcMaF and their results
      thus far….she has about 10 people and four results; one excellent,  one
      mild and two no response. If you’re taking it you

      can tell her how you’re doing here.
    • Mindy Kitei Investigates GcMaF- Mindy
      Kitei noted that Dr. Meirleir reports that 80% of his patients feel
      significantly better on GcMAF and Nexavir digs into whether some SNP’s play a
      role in who responds. Just below that post is another post exploring the ins and
      outs of this issue.
    • GcMAF poll

    • Dr. Mikovits and Annette Whittemore
      Talk in Santa Rosa
      - Lannie has provided a nice overview of the first part of Dr. Mikovits, er Annette
      Whittemore’s talk (Annette had to step in for a bit when Dr. Mikovits plane was delayed). The dangers of sample freezing were
      mentioned again….could such a simple (but perhaps overlooked) factor be causing the negative results? We also heard that
      XMRV infection rates in families seem to be evenly split between men and women and a closer look at those original
      samples found a second strain of XMRV in about 30% of them. For more check out the overview
      here.
    • The Canada Studies – a Key Figure Shows Up? - in the look at
      the year ahead in CFS a set of very interesting Canadian XMRV Studies were
      missed. These studies, done in full communication with the WPI, were started
      last July and involve Dr.
      Stein, Dr. Tyrrell and Dr. Houghton at the University of Alberta. 

      Dr. Houghton
      is an intriguing figure. He was nominated for the CFSAC panel last year by the CFIDS Association of
      America and was accepted. He kind of snuck in under the ME/CFS Community’s radar
      but he may be the most celebrated researcher yet to serve on the panel. A former
      Lasker award winner for the discovery of hepatitis he was described in this way
      by the Pres. of the Univ. of Alberta.



      “Michael Houghton’s discovery of the hepatitis C virus is one of the most
      significant biomedical breakthroughs in the last 20 years. His work is the
      foundation of research to improve and save the lives of millions of people
      around the world. Having him as part of our already impressive team of
      scientists and the recent establishment of the University of Alberta’s Li Ka
      Shing Institute of Virology together propel the University of Alberta to the
      forefront of research into virus-based diseases.”—Indira Samarasekera,

      president, University of Alberta

      He has no background at all
      in CFS
      and Kim McCleary was pleasantly surprised he accepted their offer.  He was quite
      intrigued by EBV connection at Science Day and clearly touched by some of the
      stories and openly talked about wanting to
      get the pharmaceutical industry involved in a study. In the past year he
      received the Canadian Excellence Chair for Virology and he joined the newly established
      Li Ka Shing Institute of Virology which received $75
      million dollars in grants at the University of Alberta. In his interview he
      talked about doing three things; two involved hepatitis C (170 million people
      around the world are infected) and the last was uncovering new viruses at play in diseases.
      No mention was made of CFS or XMRV but he is involved in the Alberta XMRV
      studies. In any case, connections do matter and one wonders if Dr. Houghton
      might have gotten connected to CFS at a very opportune time.

      His presence at the
      CFSAC panel is an illustration of the increasing prominence of many of the
      members. With Dr. Lipkin, Dr. Singh, Dr. Holmberg and an HIV head at the Univ.
      of Pittsburg all nominated to the panel (by the CAA – no other nominations are
      known, if any were received) hopefully more major figures will soon be joining
      Dr. Houghton.

    • Wellcome Trust Researchers Respond to Criticisms
      – that they went too far in their conclusions by
      stating that they believe that they did not, that they believe that ‘patient-derived XMRV’ contains
      too little sequence variation for it to be a human pathogen, etc.

    • Dr. Mikovits Clears Up Reported Conversation On Anti-Retroviral Success -
      A
      report bounced around the Internet of a conversation with Dr. Mikovits in which
      she stated high rates of antiretroviral success with XMRV infected patients. In
      a statement provided by Dr. Deckoff Dr. Mikovits reported that while some
      successes had been the seen the report was much too optimistic.

    • Dr. Racaniello on Why Anti-Retrovirals Might Not Work With XMRV
      - and hence
      why limited success with ARV’s doesn’t mean much about XMRV in humans…..the
      general jist is that if the ARV’s stop viral replication -and the virus is doing
      its damage by replicating then you’re in good shape…but if it’s doing it
      damage some other way – then, you’re not….and nobody knows how XMRV does what
      damage it may be doing. 

      We
      know that some anti-retroviral drugs will inhibit XMRV replication
      in cell culture.
      That
      does not mean that these drugs will alleviate
      disease (assuming, as you
      say, that XMRV causes disease). It depends
      on how the virus actually
      causes disease. For HIV, viral replication
      kills T cells, causing
      immunodeficiency and eventually death from
      opportunistic infections.
      We don’t know if XMRV destroys certain
      cells, leading to ME/CFS -
      we don’t even know where the virus
      replicates. One
      possibility is that the viral DNA integrates next to a
      cellular gene, activates
      it, and that causes disease. In that case, in
      a patient with disease,
      treating with an antiretroviral will not
      affect disease because
      viral replication is not the cause.

    • CFIDS Association Decries Media Dedicated to Sound Bites and Suggests “We’ve
      Only Just Begun” Understanding XMRV
      – In her  letter from the CEO’s desk
      letter “Headway, Headlines and Healthy Skepticism” for January Kim McCleary took the media to task for not using source
      documents and stated that vital XMRV studies were unaffected by the media blast
      (largely begun in the UK). Besides the ‘Big Two” (Lipkin and BWG) she stated
      other researchers were continuing their efforts unabated and that they would
      incorporate the study findings into their efforts….. something Dr. Bateman
      eluded to in her earlier webinar. 

      Other
      researchers involved in the study of XMRV affirmed plans to continue studies
      and/or preparation of manuscripts of data already collected, with some adding
      that they will take even more steps to reduce the possibility of contamination
      by routes elucidated in these papers and/or to test samples in additional ways
      for mouse DNA. All were sensitive to the fact that these papers likely raise
      review standards for future study applications and results.”Dr. Mikovits and Dr. Ruscetti have raised some questions about the advisability of using the IAP tests.
      The papers apparently also pushed the BWG to employ culture tests – by far the most effective way the
      WPI has used to find the virus – and something that was not on the BWG’s docket before.

      Reaching back 20 years she also noted that CFS was associated with three
      different possible retroviruses over six years in the early 1990′s and many
      people thought those investigations ended early. Of course, science is much more sophisticated
      now and more resources are being devoted to XMRV. In any case Kim McCleary’s and
      Dr. Komaroff’s warning that it will take multiple studies to prove anything pointed out
      the fact that even if Dr. Lipkin finds XMRV in six months – that finding will
      have to be validated by more studies for a consensus to occur….The complete
      story on XMRV will take some time to unwind no matter how it turns out.

    • The BWG Transcripts Intrigue
      - the full transcripts of the
      BWG meeting are available and contained some real shockers. 

      The Craziness of it All – Lo/Alter and the IAP test - this is the stuff that makes patients and, no doubt, researchers
      crazy. If anything seemed clear after at the Retrovirology papers it was that the consensus was that if you’re going to
      search for mouse DNA – that IAP test was the one to use  – not the mtDNA test used by
      WPI and Lo/Alter. The talking heads on the Twiv broadcast, in fact, (if memory
      serves) suggested that Lo/Alter go back an retest their results with the ‘more sensitive’ IAP test.

      The transcripts indicate, though (thanks Biophile), that at two points during the Workshop Alter noted they
      did use the IAP assay and that it was
      actually ‘much’ less sensitive that the mtDNA assay the other researchers were turning their noses up at
      - some of them found it was less sensitive than the mtDNA test….which brings
      up the question that everybody must have in the backs of their minds after all
      this – Is there anything retrovirologists cannot disagree on?

      Like Fish in Water - Mark pointed out that the ‘recovered patients’ from the Bell Pediatric cohort in the 1980′s actually scored significantly
      lower on some functionality/wellness surveys than the healthy controls – suggesting that
      while they were
      better relative to how ill they had been but they were not ‘recovered’ or completely well. This brings to mind
      Staci Stevens statement that few people ‘really recover’; while they can definitely improve what they really get good at is
      managing their illness within definite boundaries…..ie. . they are still fish swimming in the ME/CFS water.

      The Hanson study was more a beginning point than an endpoint, by the way. Dr. Hansen called it a ’20/20′ study which suggested to me
      that they just had a quick snapshot of something they will be digging into more deeply. Dr. Hansen stated “
      We are still working out our assays for looking for the MLV-like viruses. We have a number of assays that we have tried, and I’m going to mention these. But we’re still not sure which are the best ones to use. We have results
      from all the different assays, but we are still, as I said, in progress.
      .

      She is being very careful about contamination; collecting blood in a special
      room, UV irradiating all tubes before using them, and UV irradiating the first PCR stage. They sequence everything
      they find to ensure that they are getting the sequences they are looking for. (The WPI does the same thing).

      Fully twenty percent of her 20 controls were positive – a surprisingly high number – which she attributed to
      them living near, and sometimes being the friends of, some of the people with ME/CFS.

      Cranky PCR’s – the most shocking thing about her presentation came when she talked about
      getting different results on different machines and the ‘limits’ of detection. We are at the limits of detection. We will have a sample positive one time and then negative another and then positive the third time. The PCR is really tricky. As I said, sometimes when we got inconsistent results, we discovered that one person was using one PCR machine and another person was using the other. So you really are at the limits of detection with the PCR. That’s why
      we want to get at least two positive results before we count a sample as positive.

      LnCap and XMRV AND MLV’s? – in her presentation in Sweden Dr. Mikovits suggested whether the LnCap cells researchers are
      using to culture XMRV just weren’t very effective at growing MLV’s. This is what Dr. Klimas had heard but Dr. Hanson had
      a different experience, stating…That is the conventional wisdom. We have actually never seen what is called classic XMRV. We have only gotten these polytropic-like sequences from the LNCaP cells. I can’t explain that at this point,
      but, in fact, what we are seeing is polytropic-like virus in the LNCaP cells.

      We’ve kind of forgotten about positive Hanson study after the excitement from the Lo/Alter study but it seems likely that more surprises may very well be in store from her. Dr. Hanson is still the
      only researcher other than Dr. Lipkin to have scored an NIH grant on CFS and XMRV.

      The Bagni Connection -
      Dr. Bagni is definitely getting around…In her presentation in Sweden Dr. Mikovits noted that Dr. Bagni correctly identified a
      high percentage of WPI positives using her antibody test and here, Dr. Hanson reported she did much the same thing with her
      samples. (This means the Bagni is not ‘specific’ for XMRV but picks up MLV’s as well.) Dr.
      Bagni co-authored the original Science paper and has published 7 papers over the
      past five years or so – mostly on Karposi’s sarcoma. She seems to be in the
      thick of things regarding antibodies which suggests that we’ll hear more from
      her late.

      Dr. Lo’s Unique mtDNA test – we get the idea that an mtDNA or IAP test is something
      you pick up off the shelf….but many of these tests are being developed as we go along. A closer look at the
      Dr. Lo’s testimony indicated that he had developed an entirely new mtDNA assay…and then used it to
      check his other assays….This is the assay that is 1,000 times more sensitive than the PCR assay they
      are using to check for XMRV…and its the one Dr. Hanson wants to get her hands on.

      Can this be a contamination by mouse DNA? The mouse DNA genome contains endogenously
      many copies of the related retrovirus sequences. We thought this would be necessary for us to
      develop an assay to verify that there is no contamination of mouse DNA in the assay system we use and
      also in the clinical samples that test positive for MLV-like virus gene sequences.

      Dr. Coffin’s Learning Curve – After that it was kind of shocking to read Dr. Coffin say that
      he actually recommended Dr. Lo do the mtDNA assay….before he recommended that he not do it. When
      experts like Coffin get befuddled like this we are surely on the cutting edge of science. Of course, like
      everyone else
      Dr. Coffin has developed his own assay – an IAP assay which he stated was more sensitive -and
      which suggested to him that what appeared to be MLV’s were, in fact, contamination.

      Dr. Klimas and Sample Storage – Dr. Klimas, who is not a retrovirologist, jumped in with a question about
      sample storage, of all things. Dr. Klimas asked about freezing and rethawing the original samples -
      something Dr. Mikovits later suggested in her Swedish talk could disrupt the virus -
      making it impossible to find. She stated that only the WPI and Dr. Lo had used samples had
      not been refrozen several times. Dr. Peterson, who has completely dropped out of sight on XMRV, but is
      rarely in sight anyway :) , early on noted they had dug XMRV out of a 20- something year
      old sample but even that sample might fit the bill if it had remained frozen throughout.

      DR. KLIMAS: The samples that were in the freezer all these many years, had they been manipulated — frozen/thawed or in any way –
      DR. LO: No. Regional samples in this study have been kept frozen for all this period of time. They have
      never been thawed out to use for different studies.

    • Canada XMRV/Viral Studies Reportedly Under Way – In the’Hope for ME/CFS Sufferers’ blog Dr. Timothy Luckett states two viral studies are underway at the
      University of Alberta in Canada. Here is what was posted “Dr. Mason’s study is about trialling antiretrovirals, finding causation, transmission, and prevalence. The study by Tyrell and Houghton is to show cause.
      In a recent talk, Dr. Tyrell states that “I have suspected that CFS is a communicable viral disease since the Incline Village Outbreak at the beginning of my career, and I am confident that we are closing in fast,
      and excluding viral pathogenesis at this point would be utter foolishness.”
      . Dr. Houghton is a CFSAC
      panel member who has expresssed interest in herpesviruses role in ME/CFS.

    • Another ‘XMRV Conference’
      - XMRV won’t be headlining the HTLV and Related Viruses Retrovirology
      Conference in Belgium from June 5th to 8th but it will be one of the three main topics. The Scientific
      Committe for the XMRV session includes Dr. Silverman of the Cleveland Clinic (original co-author) and Dr.
      Heineine of the CDC. Thanks to Overstressed for finding this.
    • ‘Intrepid’ Researcher Starts New XMRV Study - Dr. Joliceur was unable to find XMRV
      in his first go around but he is having another look. In this study – which is
      similar to the Dusty Miller study that we believe will get started soon – Dr.
      Joliceur will  be looking for XMRV in people who already tested positive
      for the virus. Good luck to another researcher willing to brave the sometime
      turbulent ME/CFS
      waters. 

      “From ME/FM Action Network – Dr. Paul Jolicoeur is a researcher in Montreal who is doing research on the virus XMRV.
      He is looking for patients to act as positive blood controls for his study on XMRV. He is requesting that due to distance difficulties only patients in Ontario diagnosed with ME/CFS who have previously tested positive for XMRV on the blood test by the Reno Nevada testing centre contact him at his address. He needs blood samples of positive patients to act as positive controls in his research study about the SMRV virus. He wants you to contact him directly at:Paul Jolicoeur M.D. PhD.

    • Whittemore-Peterson-Institute Says Happy New Year – Nothing Has Changed
      - Annette Whittemore
      started the year out with something of a blast – taking the Welcome Trust author to task for his statements that
      XMRV does not cause CFS…and that the results of their study remain fully valid
      and are backed up by multiple layers of evidence – in contrast to the PCR studies…and noted that
      100′s of individuals diagnosed with ME/CFS have tested positive for XMRV. She stated that
      the only thing the Retrovirology
      papers indicated was that XMRV studies cannot be undertaken in a mouse lab without
      extreme caution (the WPI is not a mouse lab) and should not rely solely on PCR. 

      She suggested that one reason for XMRV’s difficulties was that it
      threatened scientific dogma….and that overturning scientific dogma required
      unusually high levels of evidence and then provided glimpse of the WPI’s vision of XMRV – or rather the family of gamma retroviruses – and it is a big one;
      that they believe these infections underly neuro-immune diseases and untold numbers of cancer.

      She made it clear that the WPI believes that it’s past time for novel treatment trials. She also noted that the WPI’s research projects are revealing that an array of neuro-immune disorders
      are infectious and inflammatory in nature. She noted that
      XMRV researchers are ‘enthusiastically’ continuing to deepen their understanding of the pathogen.

    • Dusty Miller Study Saga Continues – Ecoclimber posted a
      prospective XMRV pilot study from  Dusty Miller, a noted retrovirologist at
      the Fred Hutchinson Cancer Institute on the both the Phoenix Rising and ME/CFS
      Forums to begin to round up people who had tested positive for XMRV. The posting
      was meant  to be followed up with a fuller explanation of the study and an
      interview with Dusty Miller explaining  the study and his research but the
      posting turned out to be premature as IRB approval had not been granted. The
      post was quickly removed from the PR Forums but unfortunately stayed up on the
      ME/CFS Forums where it received a reception not unlike a CBT trial might
      receive. 

      Soon posts and blogs went up warning ME/CFS patients not to take part
      in the study..Both Dusty Miller and an assistant showed up at various times to
      try to answer questions. Miller was accused of not having any experience in
      MLV’s (some fact-checking was definitely missed on that one:)) and Andy, his
      assistant – was accused of lying Many members, of course, understandably simply
      wanted more information on what could be a very important study on XMRV…..
      Finally it was confirmed that Dusty Miller was Dusty Miller and that Andy was
      Andy…and a set of questions has been deposited with him that will hopefully
      clear up some fears.

      The fate of the study to my knowledge is unclear. It still
      needs to receive IRB approval; if and when that happens and the study resumes
      the scope and methods of the study will be fully revealed and then the
      discussion will begin anew :)

      Check out an evenhanded blog on the happenings.


    • Exhausted by Illness and Doubts
      - the NYTimes plopped a largely sympathetic
      and even-handed article on XMRV and CFS into its popular Tues Health section.
      Highlighting what a volatile issue XMRV has been over the past year, the article
      documented the ups and downs of the past year; the FDA panel recommending that
      blood donations be banned, the four Retrovirology papers that shortly followed,
      the emphatic statements by Greg Tower that it was over, Dr. Racaniello’s
      agreement, then his backtrack then his outright rebuttal and Dr. Mikovits
      refutation. M
      ary Schweitzer got in there and Michael Allen got the last word in
      saying essentially ‘walk in my shoes for awhile and then tell me not to try
      anti-retrovirals” 


      The Blog!
      - Even better, truly are the comments underneath a NYT’s blog pointing to the article. The NYT
      probably guessed they would get a boatful of comments and they did – with 112
      comments already – helped out in part by a “Dr. Santana” who
      said all people with ME/CFS need to do is, yes, exercise more…..to get better…
      and ‘Skeptic’ clearly hailing from the UK, who believes we will all being see
      psychs in the future…..

    • Viral Integration into the Human Gene….1/2 Way There -
      Dr. Racaniello gave us a
      science lesson on viral integration in his Virology Blog. We keep hearing that viral integration into the human
      genome will go a long way to lay to rest some researchers fears about XMRV. It
      turns out that viral integration is just like it sounds. Once a virus gets into a cell it uses an enzyme called reverse transcriptase to
      turn its single-stranded RNA genome into the double-stranded DNA used by our cells. Then it uses an
      enzyme called integrase to integrate the viral DNA into our DNA. How to confirm this has happened? ‘Simply’
      amplify the viral DNA sequences and determine if they are bordered by human DNA.
      (‘Simply’ may considerably understate the complexity of this task since it has
      not occurred with ME/CFS yet and only partially prostate cancer). If viral DNA
      is bordered by human DNA you have evidence that the virus has entered a human
      cell and burrowed into human DNA. At that point it doesn’t matter where the virus came
      from; it’s now infected a human cell and is now an infectious human virus. 

      Why is XMRV only halfway there? Because the Silverman team proved that one side of the
      virus was bordered by human DNA but not the other. Although they were able to show
      human DNA was present in every sample, and if one side is integrated in human
      DNA, it would seem strange that the other side wouldn’t be, Dr. Raccaniello wants more.

      The isolation of the entire proviral DNA, including both flanking integration sites, from patients with prostate cancer or chronic fatigue syndrome
      would be additional evidence that XMRV is a virus that infects humans.

      Finding XMRV was integrated into human DNA would still apparently not clinch
      it for
      Dr. Racaniello – note that he’ll only go so far as to say ‘it would be additional evidence’…One wonders what
      would clinch XMRV being a human infectious virus for him (and I will ask in his blog).

      Down the Rabbithole – Dr. Alan Dove, in a comment posted to the blog, wants to dot even more i’s and cross
      some more t’s. He stated that

      Besides looking at the other end to check for duplication, I’d also want to see some blinded samples from healthy controls. That’s especially important in this case, as they’re doing a preliminary linear amplification on the patient samples before doing the junction PCR. With that much amplification,
      and with the first step open-ended, I think there’s some room for PCR artifacts.

    • The ‘Hard Truth’ from Dr. Deckoff-Jones
      - she’s never been a
      cheerleader but has always presented her and her daughters story in a very sober
      manner – a very difficult thing to do when you’re representing the hopes of many
      people. Her latest post starts off Unfortunately,
      fulfilling my prime directive here involves reporting the bad news with


      the good.”
      and then comes news of a severe crash, the worst in about a year, after
      walking for a long distance at the LA airport.  She got to the point where
      she could literally not take another step in and had to sit down on the floor at
      the LA airport.  In true CFS fashion she did okay that night and crashed
      over the next couple of days. Yes, the antiretrovirals seem to have helped – they got her to the
      airport! but normal functioning is still a day dream. 

      A Mixed up Clinical Picture – XMRV is turning out to be more complicated than most of us imagined. She
      notes that some people who one would think would test positive for the virus (probably really ill people) sometimes don’t
      while others do (such as me:)). People who have the same symptoms and the same disease presentation
      are sometimes getting different results from XMRV testing. It’s confusing although she does note
      that the culture test may not be picking up the p MLV ‘variants’ giving us an
      obscured picture of who’s infected with what. People could have XMRV alone,
      XMRV plus pMLV’s or p MLV’s alone. If the anti-retrovirals are not working
      against p MLV’s then the two groups might not be getting better. The antibody
      tests should be picking up everybody. People who are testing positive  by
      antibody and negative by culture could be harboring p MLV’s. Of course much work
      remains to be done to validate the existence of p MLV viruses (not just gene
      sequences) in humans.

      The Hardest Truth - is simply that the first ‘informal unpiloted trial’ of
      antiretrovirals suggests that while they have generally been well tolerated and can ‘move the illness’ in some they are not working well for most. “Most patients taking antiretrovirals are reporting very modest or no gains on
      various combinations of the drugs for various lengths of time.” She does leave open the possibility that
      slow improvements may continue over time.

      Should we have expected these drugs to work? They may work against XMRV in the lab but XMRV
      is not HIV. Is it too much to expect the first drugs that were tried out to work? I asked Dr. Deckoff in her blog.
      “If AZT and other drugs work well in the lab against XMRV should we necessarily expect that they would work in the body?”

      She responded
      “We already have clinical evidence that they do work in the body, but the drugs
      we have can only inhibit early stage events of viral replication. Latent provirus can still
      activate and generate new viral particles, fueling persistent immune activation.
      This type of chronic immune activation is now known to be very important in the progression of
      HIV infection to AIDS. Unfortunately, we don’t have a protease inhibitor that works in
      vitro against XMRV, so we are limited to other strategies for maintaining latency.
      We need specific drugs.”

      There’s more – a discussion on glutathione and a short one on the intriguing
      theory that XMRV could have ended up in vaccines.

    • Dr. Rein and Dr. Racaniello on Twiv cont.- Dr. Rein emphasized an important point on sequence variation. He noted that if the sequence you’re looking for is a little different from the published sequence then you can miss it. He said that was an inherent ‘risk’ in PCR and can lead to false negatives. (That risk does not apply to the immunohistochemistry results – which are just coming on CFS now). From that we can conclude that sequence variation is a real question given the newness of XMRV and how little researchers understand it. How antibodies constructed to match up XMRV and other similar viruses should be able to pick it up. 

      The Big “C” again (and again).
      They went into a scary scenario – which does not seem to playing out at all – of the water controls researchers use possibly being contaminated from mouse DNA from mouse droppings coming from reservoirs. (No water controls have tested positive….this is not an issue with the XMRV studies). They
      then went on for a while about contamination possibilities…a millionth of a microliter of mouse DNA (much less than a cell) would be detectable da da
      da….no need to spell out all the gory details.

      The 22Rv1 cell line – Not a Smoking Gun - The 22RV1 cell line has become an area of controversy. Dr. Rein reported that he found that the cell line produces XMRV; ie has become infected with XMRV probably when it was passed through nude mice a couple of decades ago. One of the papers found that XMRV was less diverse than the XMRV in the cell line and therefore concluded that XMRV was probably derived from it. This may have been THE major finding of the four papers – and it seemed very convincing at first but doubts have definitely crept in….Dr. Rein did not agree it was possible to conclude that XMRV was derived from that cell line, and after being initially rocked by the finding, Dr. Racaniello came to the same conclusion. In fact 3 of the 4 commentators – after cheerily espousing on all the dangers of contamination – all agreed that this central finding had been overstated and one of them actually put up a blog post about that. The papers do put a stronger focus on the possibilities of contamination – and the 22RV1 theory could be correct but it has certainly not been proven to be correct or to apply to the WPI’s or other studies. They all agreed that what the field needs is what it is doing; creating strict protocols and sharing samples between labs.

      A Definitive Test - XMRV Integration into human DNA. What clinched XMRV for prostate cancer was showing that it was integrated into human DNA. Dr. Rein wanted that finding replicated by other labs and it to be extended to CFS. He noted that Illa Singh is trying very hard to do that; the problem is that it takes a lot of DNA and prostate tumor biopsies do not provide much of that….

      What about those Antibodies? They finally got to the big question the patients have been asking – what about those antibodies? Doesn’t
      THAT prove a real infection has occurred? Dr. Rein simply said… another lab
      needs to replicate those findings. (Dr. Mikovits has reported that Dr. Bagni’s
      antibody test at the NCI confirms the WPI’s findings; her study has not been
      published yet.) Of course many labs are developing their own antibody tests and
      some are finding it and some are not…..

      Doesn’t the ability to transfer virus from blood to cells in culture mean virus is there?
      -
      This has been a big argument from the WPI. Dr. Rein stated that if XMRV is floating around in the lab then it could get into the
      samples that way.

      How could ME/CFS samples consistently show higher rates of XMRV infection than the controls? Dr. Rein suggested if the ME/CFS samples were handled more
      it might….but otherwise he didn’t have an answer to that and said he didn’t think ‘we’ have an answer to that.

      What is next? Using validated assays…exchanging samples…..using different labs. Dr. Rein does not believe that large-scale case-control human studies are called for – which makes sense; what assay, after all
      ,are you going to use to test all those people? Instead he called for developing a consensus assay and then moving on – which is essentially what is occurring.
      He was clear that he believes it’s possible that XMRV was a ‘mistake’ (I think
      he leans this way given the way his prostate studies have turned out) or that it
      is is a virus infecting people.

      Conclusion - discussing the four Retrovirology papers was
      never destined to be a fun experience. However, all the researchers agreed the
      XMRV’s options are still very much open and that we still have much more to
      learn and that several of the ongoing should tell us a lot.


    • Dr. Alan Dove
      - one of the participants in the Twiv talks takes researchers
      on both sides of the XMRV to task for going too far in his blog.
    • Retrovirology Study Media Roundup - A check on Google news came
      up with no less than 135 articles on the Retrovirology papers, most of which
      overhyped the findings – helped to a great extent, no doubt, by co-author Greg
      Towers rather definitive statements. The top story, though, was by Nature.com
      which came to a more sedate conclusion typified by Dr. Lipkin’s remarks


      “These data emphasize the importance of strict attention to molecular hygiene,”
      says
      Ian Lipkin of
      the Mailman School of Public Health and College of Physicians and Surgeons at
      Columbia University in New York. “They also raise concerns about some findings
      in earlier studies. However, they do not exclude an association between XMRV or
      related viruses with either prostate cancer or CFS.”

    • Blood Working Group Reacts – everybody seems to feel the need to react to the four papers on
      contamination in the Retrovirology Journal of all about a week ago. The BWG stated, yes,
      of course, we and the labs are and always have been concerned about contamination and they are proceeding with phase III
      which will look for RNA, DNA and antibodies. Interestingly, they talk about culturing this is something that we thought
      that the BWG, which is focused on faster methods of detection, was not going to do
      but they noted how important it is to be able to
      culture (and isolate?) the virus itself and antibodies to it. As Dr. Lipkin noted in his comment PCR is
      not the end-all and be-all of testing for viruses and the BWG appears to agree.

    • This Week in Virology
      - session #112 of the  Twiv podcast with Dr.
      Racaniello featured XMRV and the head ofthe National Cancer Institute, Dr. Alan
      Rein. They started off tonight with a good laugh when Dr. Racaniello told Dr.
      Rein they had a him on so he could clear up all the issues regarding XMRV. Dr.
      Rein has worked extensively on murine leukemia viruses and HIV. Dr. Rein noted
      that the gene sequences found by Dr. Lo and Alter were gene sequences commonly
      found in mouse DNA and in endogenous retroviruses. Dr R noted that they went to
      a lot of trouble to ensure that these are not gene sequences from mice. Dr. Rein
      agreed that did not think that the mitochondrial DNA test that they did was the
      best test for mouse DNA and felt that IAP DNA assay would have been quite a bit
      more sensitive. 

      Because one study showed it was possible for a mtDNA test to miss mouse DNA
      that the IAP test is able to pick up they agreed that it would be best for the positive
      studies to go back and retest their samples using the IAP test. (This suggests, though, that the
      mtDNA is completely inadequate for finding mouse DNA. Sure it’s possible that it misread some
      samples…but how is it possible for it to misread 70 out of 100 samples? So, yes, for accuracies
      sake, go back and retest the samples….but to fine tune the results – not overturn them…

      Variable enough? -a big question making the rounds is if XMRV (or the Lo/Alter sequences)
      are genetically variable enough. A replicating virus should be quite variable from person to person while a contaminant
      would not. XMRV does
      not, as yet appear to be very variable genetically. Dr. Rein noted, however, that XMRV is very different from HIV and, given
      that, there is really no way to tell how variable a replicating XMRV should be.

      The Prostate and Dr. Singh - Dr. Rein also looked for XMRV
      in hundreds of prostate cells and found none. Rather disturbingly he described a
      process, too complicated for me to get on the first pass, in which it was
      possibly for immunohistochemistry samples to register as false positives.
      Immunohistochemistry has been Dr. Singh’s bailwick; she has claimed that
      immunohistochemistry is  more accurate than PCR in finding XMRV but Dr. Rein reported that his analysis of
      some of Dr. Singh’s positive slides suggested that they were actually negative. Dr. Singh, appears to be
      using immunohistochemistry in her XMRV autopsy study. Dr. Singh, of course, was not on the program and did not have a chance to defend
      her study. Dr. R did note that a recent paper came out that did found XMRV in prostate cancer tisssues…..the twists and turns this field
      is still taking continue to be amazing.

      More on the podcast tomorrow.

    • Dr. Racaniello Retracts Statement About XMRV and CFS- showing an admirable commitment to the pursuit of the truth Dr Racaniello made an abrupt about face regarding his statement that the four papers were ‘probably the beginning of the end of XMRV and CFS’. His new blog “XMRV and CFS- It’s Not the End’ paints a very different picture and, to me, Dr Racaniello’s new piece demonstrates just how difficult a subject this is. Dr. Racaniello runs a research lab – he is well versed in this field yet this is what it took for him to alter his opinion 

      “I read the papers over again, and began checking XMRV sequences in Genbank. I also began an email correspondence with authors of three of the four papers, and spoke with my virology colleagues here at Columbia. As a consequence of this additional research I decided that my initial impression of the papers was incorrect, which is evident in my post entitled ‘Is XMRV a laboratory contaminant?”

      This is difficult stuff! He does believe that the new papers do highlight the dangers of contamination but they do not imply that the positive results from the WPI’s or other studies were contaminated. He is fully in line with Dr. Coffin, here, who co-authored two of those papers.

      “Upon re-reading three of the four Retrovirology papers it became clear to me that they show that identification of XMRV can be fraught with contamination problems, but they do not imply that previously published studies are compromised by these findings. Clearly any new studies done on XMRV should keep in mind the potential for contamination from PCR kits and murine nucleic acids.”

      Three of the papers were nothing but warnings; the Hue paper was the most substantial one and the one that bothered him the most but here, again, he was able to find reasons, some of which the WPI mentioned in their rebuttal, why the Hue paper might not apply to the WPI’s findings. He seems to be indicating, oddly enough, that some XMRV isolates appear to be laboratory contaminants while others do not – was an amazing twist in an already very complex field! However, this is a twist that should be able to accounted for one would think – simply by analyzing the different strains (?). Vectors from the MoMLV virus appeared to be used in gene therapy, by the way, which is one reason they might be present in labs. The WPI, however, said the type of mice Hue described have not been used in their labs.

      The idea that PCR amplification could itself cause increased variability in 22Rv1 making it look like the ancestor to XMRV indicated just how complex all this is. Willow on the Phoenix Rising Forums has provided a way this could occur.

      “I was initially more troubled by the fourth paper by Hue and colleagues. There are four major findings in this paper (gag PCR primers are not specific for XMRV; the virus is present in 5 human tumor cell lines; two XMRV isolates are nearly identical to a virus from the human prostate cell line and also contain an insertion from the murine retrovirus MoMLV; and there is more nucleotide diversity in viral sequences from 22Rv1 cells than in all the patient XMRV sequences). The fact that two XMRV isolates seem to be laboratory contaminants – judged by the presence of MoMLV sequences – was initially unsettling until it became clear that other XMRV isolates do not have this insertion. That leaves the fourth finding – that XMRV from 22Rv1 cells appears ancestral to, and more diverse than, all the human XMRV sequences. I decided that this result was less troublesome than I had originally believed, in part because it is not clear that the differences among the 22Rv1 viruses did not arise during PCR amplification.”

      He concluded the blog with an apology and stated that the research on XMRV and CFS must proceed and, in fact, called for it to increase.
      My conclusion is that these four papers point out how identification of XMRV from human specimens can be complicated by contamination, but they do not mean that previous studies were compromised. They serve as an important reminder that future experiments to identify XMRV need to be appropriately controlled to ensure that the results are not compromised by contamination.

      In other words, these four papers are NOT the beginning of the end of XMRV and CFS. Rather, research on the role of this virus in human disease must proceed, with large, case-controlled epidemiological studies, as suggested by others.
      I would like to apologize to anyone who was offended, angered, or disappointed in any way by my statement to the Chicago Tribune. It is my goal to educate the public about virology, and clearly I did not do that very well.

      There are at least two lessons that you can take away from this incident. First, that I make mistakes, and that I’m willing to admit it. Everyone does, including scientists. Second, if I had difficulties interpreting these papers, how would non-scientists fare?

      The Chicago Tribune has printed his retraction

    • Respected Retrovirologist Tackles XMRV/Retrovirology ‘Superteam’ Formed to Rebut Claims - the biggest news of the day, however, was not Dr. Racaniello’s retraction but EcoClimber’s statement on the Phoenix Rising Forums stating that the Retrovirology papers have prompted noted retroviriologist Dr. Dusty Miller at the Fred Hutchinson Cancer Research Institute in Seattle, Washington to dive into his lab to investigate the contamination claims – which he does not believe will pan out and will apparently be part of a XMRV retroviral ‘superteam’ that will rebut the claims in an organized fashion. By suggesting XMRV was a contamination – wherever it appeared – Hue’s paper stepped on a lot of toes. It was Silverman, after all, who discovered XMRV in March of 2006 and since then has published 12 papers on it. Klein has been a co-author of several his papers and, of course, Dr. Ruscetti – who is very well respected in the field, was a co-author of the Science paper.These researchers may very well be doing lab work to specifically counter the Hue papers findings. Ecoclimber stated

      I talked to Dr. Dusty Miller. His lab is currently in the stage in testing and experimenting and gathering the evidence to rebut their claims. He states he can refute their claims. He will be getting together with Ruscetti, Silverman, Klein, Smith and others to post their rebuttal as a group against the negative papers.

    • Annette Whittemore, Dr. Mikovits on Nevada Newsmakers meanwhile Dr. Mikovits and Annette Whittemore appeared on Nevada Newsmakers to counter the claims of contamination that have been raised by a rather lazy media. Annette painted ME/CFS in broad terms – it is a complex illness that the WPI believes is infectious, involves many pathogens and affects the neuroimmune system and Dr. Mikovits noted the WPI has had interactions with researchers in countries around the world including Norway, Belgium and Spain. Dr Mikovits asserted that multiple tests are needed to detect XMRV because no single test (ie the PCR results in Retrovirology) is accurate enough. (Dr. Lipkin made a similar point in an email).Dr. Mikovits noted that they were ‘well aware’ of the potential for contamination to skew the results, which, of course is doubly true given co-author Dr. Sandra Ruscetti’s background in mouse retroviruses and Dr. Mikovits close connection to the Ruscetti’s. Annette Whittemore stated that the Retrovirology papers ‘do not change their findings’ and that “we are moving forward in a positive way”. She also noted that they were not apprised of the results before they were published – suggesting that the original authors are usually give a bit of lead time to respond to negative papers published regarding their findings. Dr. Mikovits noted that any large discovery is going to lead to ‘a lot of pushback’ because the best science always leads to ‘more questions than answers’ and that’s what has happened. (Has it ever! The XMRV discovery pushed researchers into fields and into digging up questions that they had never asked before.)

      When the interviewer asked Dr. Mikovits why researchers have not followed the exact methods of the original paper her reply was very interesting. She said that researcher do what they know how to do well and that they do the advances of the last decade very well but that those kinds of techniques are just not ready to take on a new virus like this. (If I paraphrased correctly!)
      Those new techniques have replaced the old-fashioned method of culturing, which is difficult, expensive and time consuming. (Dr. Mikovits has been saying it’s not about the
      PCR for months). She said researchers think ‘if we can detect HIV using this method we should be able to detect this virus” but
      ‘that is just not the case at this point, it is too early in the discovery process”.

      Caught in a Time Warp? (This point
      has confused me because they did use PCR to detect the gag sequence in the original paper and PCR. of course, is described by
      other commentators as something virtually any lab can do. How does this laymen make sense of all this? Perhaps PCR detection of XMRV is so difficult that just the right techniques required to find it.
      It could be that small things, unbeknownst to the research community now, are able to knock XMRV off – and this is in fact what
      the NCI is looking at. In that case, until the PCR techniques are perfected then culturing and growing more virus and then studying it -
      figuring out it’s little secrets – and then developing the correct PCR test would seem to make sense. I am just a laymen – no special expertise here – trying to think through these issues. .Sometimes I get it right – sometimes I get it wrong; take everything printed here with that grain of salt! 

      Unfortunately the PCR test was regarded as the main finding of the Science paper – it was what got the lion’s share of attention, and PCR, as Dr Mikovits pointed out, is what researchers in this field generally do now…. Dr. Lipkin and Dr. Miller and others are wary of PCR as the be-all and end-all of detecting viruses, and they are pursuing other means…

      Annette Whittemore noted all the other groups at the NIH, NCI, Cornell and University of Utah that are moving forward. When asked about politics Annette Whittemore noted that these issues are money intensive with a lot of stakeholders and some politics is inevitable….When XMRV turns out its going to cost some stakeholders a lot of money (and, of course, make money for some others).

      WPI Clinic Physician Chosen A physician has been chosen and it sounds like the clinic and research sides are coming together.
      and the immune signature paper on the XMRV published should be published early next year. Dr. Mikovits and Annette Whittemore were quite poised during this
      rather turbulent time and acquit themselves and the organization well, IMHO.

    • The Retrovirology Papers: Day Two - Not surprisingly the media jumped on the titillating but wrong story and stated XMRV was done and that it was not the cause of ME/CFS. XMRV certainly did take a hit, yesterday, but several important names, particularly Dr. Coffin – who was a co-author of two of the papers , and has been doing his own research on how to tell XMRV apart from a contaminant, refused to fold XMRV’s tent stating that the arguments against XMRV were subtle and indirect and that none of them directly indicated the WPI had inadvertently come with a contaminant. 

      Indeed three of the four papers demonstrated that they had found a contaminant but not that the WPI did. The Robinson paper indicated that one test for contamination that neither the WPI or the Lo lab used(?) was more sensitive than the mtDNA test that the WPI reportedly used. But it was only MORE sensitive; even if the WPI or Lo study mischaracterized some contaminated samples there was nothing in the report to suggest that they mischaracterized ALL of them – something that doesn’t appear to be even remotely tenable. Similarly, the Oakes paper described a situation where tests for contamination revealed that yes, contamination was present. It’s certainly a warning but both the WPI and the Alter studies tested for contamination and they did not find it.

      The Hue paper – was the only potential body blow to XMRV of the four. Dr. Hue’s phylogenetic analysis suggested that XMRV was not derived from a wild mouse but came from a cell line grown in a laboratory. Hue’s argument was that if XMRV was a human pathogen that is widespread in the population – as studies suggest it is – then it would have, like HIV, and other viruses picked up a great deal of variability. But Hue found that XMRV was actually less variable than the 22RV1 cell line his analyses suggested it was derived from. Hue, however, only used two full length XMRV genomes for ME/CFS patients in his analysis. Whether or not he needed more is unclear – he also used 1 representative of other mouse viruses in his analysis but it does make one wonder about the many unsequenced strains sitting in the WPI’s labs. Whether including them might possibly have altered his results is a question for a population geneticist….

      Hue also showed that the standard PCR test for XMRV was not as specific as had been originally thought and that it can misidentifies endogenous MLV sequences from some mouse strains as being XMRV. The misidentification is something of chimera for the WPI; the fact that they could grow viruses indicated that they did find XMRV. The WPI countered with the fact that a) they can grow the virus – so the PCR results were not simply the result of some mouse DNA getting into their samples and that their antibody test indicated an immune response had been created to a virus, not a contaminant. They did not reply to concerns about Hue’s phylogenetic analysis.

      Dr. Racaniello Does a Partial Turnaround – To read that Dr. Racaniello said that XMRV’s course in CFS was probably over was rough, considering that he has been considered to be an objective source. Over night, however, Dr. Racaniello reconsidered his opinion and the next day concluded that, while his concerns remained, he had overstated “I do not believe that the four Retrovirology papers prove that XMRV is
      not involved in human disease.”

    • Retrovirology Journal Publishes Four Studies on XMRV and Contamination Retrovirology today published
      four studies that focus on the contamination issue with XMRV. None of them are definitive, and none of them demonstrate
      that contamination resulted in the findings of the original paper, but they do indicate how careful researchers have to
      be when they explore this particular line of viruses.. 

      Check out overviews of the papers here and
      a long discussion here


    • WPI responds
      - the WPI quickly responded stating theirs and Dr. Lo’s samples were examined extensively for
      contamination and that their ability to grow live virus and the presence of antibodies indicated that
      contamination was impossible. > -

    Dec 18th
    XMRV and Chronic fatigue syndrome

    • Amy Dockser Marcus has a nice succinct blog on the meeting
    • The Limits of the Blood Working Group – the CAA’s Webinar- we’ve been kind of thinking that the Blood Working Group (BWG) is a be-all and end-all study but now we can clearly see the limits of their approach. They use very rapid testing procedures to test the blood – which means that they are not at all interested in culturing the virus. The problem with that is that the data WPI provided and their own statements indicate that rapid testing procedures are just not very accurate at this point.(Indeed they don’t appear to be used either; my understanding is that the WPI uses culture tests instead of straight PCR and antibody tests now)

      If you go back and look at the chart that shows the results of the testing the WPI did on those for patients you’ll see that they about often as not got conflicting results using standard PCR techniques. This is not really surprising since we’ve heard they’ve often had to retest the samples several times until they got a positive result

      The culture test, on the other, provides remarkably consistent results; time after time, samples that were problematic using the PCR, were positive using the culture test. But even here XMRV is difficult. The long culture time (21-42 days) indicates that even when you give XMRV a boost; when you rub it’s belly and sing soft words in it’s ears (ie you culture it)- it still takes longer than normal to show up. (Most labs culture for 10-12 days).Still the fact that it does show up very consistently does make one wonder if a good deal of the problems here could simply be the difficulty of the research community coming to terms with one of the rarest viruses yet detected in the human blood.

      Unfortunately culture tests are not used to test the blood supply and the BWG will not be assessing them.

      The Original Finding Begs to Differ – Theoretically that shouldn’t be a problem; both the WPI and Cleveland Clinic were able to find that ‘gag’ sequence without culturing or doing anything fancy – simply by using nested PCR – in the CFS patients in the original paper. Its true that they reported that they had to search some of the samples several times – but they also found it right in others. That suggests that while other labs that did one round of testing might have a harder time finding it they should be able to find – in lesser numbers. This really should not be a problem. Indeed, given the talk of treatment studies in six months – it’s hard to believe that anyone at the time thought validating XMRV was going to be difficult. Yet, last Oct was the last time “XMRV” itself has shown up in a non WPI supervised or VIPDx CFS study.
      Why that is happening is still a mystery.

      Not Storage or Preparation! - Dr. Mikovits stated at the Workshop that the storage/preparation was a major factor in the differing results but Phase II ended with no major storage/preparation issues (and one side study exploring one factor) and a mystery why XMRV seemed to want to pop up sporadically at Day II in a couple of labs.

      Possible Causes of the Disparities - Graham Simmons came up with three reasons why all the labs are not finding XMRV; subtle sequence variation/contamination/and the bug is right at the levels of detection….. Notice that we finally got the cohort question kicked off but the rest remain the same.

      If XMRV turns out the XMRV story may simply be a testament to the WPI’s sheer tenacity in looking for this virus. …once they got hint of it they like a dog with a bone and they left no stone unturned to find it; they tested samples multiple times to see if it would show up and they put it in culture long after other labs would have given up…

      NCI Collaboration – on a Norwegian Radio Program Dr. Mikovits reported “We’ve worked very hard with the National Cancer Institute
      to standardize the assays and standardize the tests so we can use the same reagants and same tests so we can be comparing apples
      to apples.” Two labs working together to test each others results and decide on the best tests definitely sounds like what’s wanted and needed. The NCI and WPI had
      very different results this round; how nice it would be to see these two labs match up the same results next time.

      Time, Time, Time – It was disheartening to learn that, after all this time, the BWG had only tested 5 samples, one of which was negative. Dr. Simmons pointed out they had, in fact, 10 pedigreed negative samples but only used one – perhaps because they are holding the others back for the big study. The BWG has taken enough of a beating on the time issue for Dr. Simmons to produce a chart showing what had happened.

      Alex3619 on the Phoenix Rising Forums dug into the chart that was presented and noted that two of the really lengthy issues were outside of the BWG’s control; in order to ensure that the negative samples were really negative they were tested and cultured by all the labs for up to 42 days plus the ethical review board took up a good chunk of time.

      Blood collection for Phase III which will involve many more samples and more laboratories will start in January and the testing will reportedly take about 6 months

      If XMRV is validated in CFS and the blood supply expect a lot of action with studies already being planned to search 2,000 blood samples dating backing to the 1970’s to see when it showed and what it might have caused.

    Dec 15th

    • A Wild Day- the Blood Working Group Reports – All thanks have to go to ValB626 on the MECFS Forums for just pouring out page after page of details from the hours of testimony and discussion on XMRV. Without it we would have had very little.It was exciting, we learned quite a bit but unfortunately little resolution was in sight and in some ways the two sides seem to have dug in deeper. It seems clear, for instance, that Dr. Stoye has made up his mind. Dr. Coffin seems to be more concerned about the possibility of contamination than before and probed Alter/Lo quite strongly but is waiting for more evidence before he makes up his mind.
      On the other hand Dr. Lo and Alter seemed very confident in their findings and asserted they have done the most sensitive tests for contamination. (Dr. Hansen later reported that she was considering switching to the Lo/Alter mtDNA test). Dr. Lo ended with a strong defense of his findings (and a little swipe at the ‘anecdotal’ evidence presented by Stoye) and with what appeared to be an empassioned appeal for more research into CFS. (He seems to be yet another figure who probably wouldn’t have come near CFS with a 10-foot pole before XMRV but has gotten hooked just as Ruscetti did, and Houghton on the CFSAC panel (another Lasker winner) and now Dr. Lipkin, it appears.

      The Test that Binds – What Coffin and others would really like to see from Drs. Lo/Alter is a live virus and/or evidence of p MLV integration into human DNA. Interestingly, the way it was worded on Vals posts Coffin didn’t seem to expect that this would have happened yet (No virus to go with those sequences, as yet?). The WPI’s ability to isolate the virus was a key factor in convincing the research world XMRV was real and its apparently not an easy task.

      Coffin has been working on determining just what is XMRV and what is not and has developed a test that can distinguish XMRV sequences from mouse sequences. We got something of an idea where he was coming from when he stated that two papers (authored by Dr. Huber and Dr. McClure?) will soon appear that determine what looked like XMRV in CFS patients was actually mouse DNA. (There was also a presentation at the Workshop that was not published which related how one researcher thought she found XMRV but later determined it was contamination . The kicker there is that my understanding is that she used mtDNA to check for contamination, which, of course, Alter and Lo and the WPI did….so it doesn’t appear that that study would bear on their findings.)

      Mt DNA Not Enough Coffin does not think mtDNA is
      sensitive enough but Lo disagreed and, in fact said their test was more sensitive than
      Coffin’s. (Love the black/whiteness of this field – the sheer clarity of it – it’s so inspiring…)
      Lo also said that mouse DNA would break up when they amplify it and they had clean, clear sequences.
      Lo then said even when they subcloned the sequences – they were exactly the same. Coffin then went into all the possible sources of contamination. Lo agreed but stated they put in many negatives which appears to mean they prepared many samples that were negative and then tested them……suggesting that if some mouse DNA had been floating around it could not have come from their lab.

      Alter Jumps In - Then Alter apparently jumped in from the audience and provided a very strong point when he noted that they tested the old samples and did new draws and found the same gene sequences which leads to the question how do you get the same contaminant twice 15 years apart? What are the chances of that? They are using different reagants, different sampling techniques, maybe different tubes, they are processing the sample immediately – yet the same contaminant shows up…..That would be incredible….

      The Limits of Detection – Hansen’s presentation emphasized how difficult this pathogen is to find.
      She did check for mtDNA contamination, had blinded samples and tried several
      different assays. She found pMLV, just as Alter/Lo did. (Stoye and Coffin
      emphasized that pMLV’s are quite different from XMRV. (A retrovirologist I talked to
      agreed; the sequences Alter/Lo found are much closer to endogenous retroviruses than XMRV is;
      he would have expected the opposite; that the Alter/Lo ‘sequences’ would have clustered around it.)

      Still no XMRV - XMRV has a really distinctive region that she searched for but could not find.
      She did report that she thought the negative studies were caused by using the wrong primers and that they are missing the pMLV’s as well because they are searching too narrowly.

      The most astonishing part of her presentation was when she
      reported that two different PCR machines in the same lab tested differently; one could find it and the other could not.
      She also had to do multiple ‘transfers’ (rounds?) of PCR to pick it up.
      We will hear about the ‘limits of detection’ several times during the talk. Could it’s rarity in PBMC’s be what is stimying the efforts? Possibly so…

      Some Recovery is Possible Without Antiretrovirals – Interestingly she found the same prevalence of XMRV in ‘severe’ CFS (POTS, etc.) and ‘recovered’ (still symptomatic but can get around) which indicates anti-retrovirals are not necessary for some recovery in some people. (Dr. Mikovits had noted this before). Coffin again pressed her about finding a complete virus…One gets the feeling that if someone could do that he would relax considerably.

      Dr. Mikovits UK study – the UK study is quite impressive and it’s a shame she can’t get it published. They shipped samples to the National Cancer Institute, which, of course, has – impeccable credentials and they used a lab there that had never tested for XMRV. They also used two independent labs and everything was blinded. They cultured the samples for from three to six weeks, far longer than other studies have tried….. It was a great cohort, all Canadian Criteria, 50% homebound…if XMRV was going to show up in any patients it was going to show up in these – and it did – 78% were positive for XMRV and 4% of controls (as in the first study).

      Coffin, interestingly, seemed to back off a bit. After suggesting some problem with the DERSE procedure Ruscetti jumped in from the audience to note the consistent results from both the gag and env regions.

      Conclusions -A Draw! Both ‘sides’ drew a little blood and both will come back to fight another day.
      Stoye is stewing about XMRV and believes the pMLV’s are just mouse DNA, Coffin is quite concerned, Drs. Lo and Alter are cooly confident, Ruscetti still can’t believe
      we’re still at the diagnostic stage, Mikovits popped in with an excellent study, Hanson can find it one PCR and not another.

      Hansen and Lo still can’t
      find XMRV, Dr. Mikovits is finding it in spades, Hansen says the negative studies using the wrong primers, Mikovits says culture for a
      few more weeks, fellas and Stoyes just scowls..the only we were missing was Dr. McClure (:) who we will apparently hear from soon)…..

      Alter/Lo still need to isolate the virus or prove its embedded in human
      DNA. The BWG seems to have no handle on what lab is ‘right’ and has alot more
      work to do. Right now best thing to do with the BWG timelines seems to be to double them and then double them again….

      We should know more after the CAA’s webinar
      tomorrow at 1p EST..Hopefully we’ll get another timeline (joy), some translation of the BWG’s findings and a reason why
      after all these months they only passed around four samples…

      Isn’t it time for Singh autopsy study? :)

    Dec 11th

    • Phase II of BWG Study is Complete (Really!) – The CFIDS Association today announced that the oh so
      important (and time consuming) second section of the BWG’s study focusing on sample preparation
      and sample storage is complete and that the results will be announced at the BWG’s meeting, just 3 days from now
      (Dec 14th) (gulp). The meeting is open to the public (if you happen to be in Gaithersburg, MD) but is not webcast;
      just three days later, though, a CFIDS Association webinar (register here) will feature two members of
      the BWG who will talk about the results and where they go from here. 

      Dr LeGrice reported they were looking at contamination issues although that has never been explicitly stated.
      Still, if contamination was to occur it would presumably occur during the sample preparation phase. At the very least the
      Group should be able to tell us how to prepare and store an XMRV sample such that it does not disappear. This suggests they should be able to
      indirectly tell us if any studies inadvertently destroyed XMRV during the sample preparation/storage phase.
      Discuss the meeting here

      Meeting Agenda – XMRV and the MLV’s will be the second topic on the meeting agenda. That discussion will take place from 1-3:30 pm EST. There will be nine presentations; Dr. Mikovits will make one of them. Here they are:

    • XMRV in Spain: Part II – details on the Spanish study have shown up and our surmises were correct; XMRV has been found in CFS, HIV and healthy controls in Spain. The sample size was very small – so any prevalence figures are very preliminary. This is not a ‘study’ so to speak; it was an attempt – after all the controversy – to see if they can find the virus. They were able to do that and it appears they will now start testing more people. We should keep in mind that they were looking for XMRV in an somewhat different set of cells- the B Lymphocytes – than everyone else has been looking in (PBMC’s). PBMC’s contain B Lymphocytes but no one has actually signaled out this group of cells and tested it.It’s difficult to ascertain prevalence even in this small study because they reported the incidence of XMRV in cell lines rather than patients and some patients (n=11) obviously contributed more than one cell line (n=21). XMRV showed up in 3 x’s as many patients as controls using the env protein, in equal numbers of controls, CFS and HIV using the gag and twice as many CFS patients (50%) as HIV and healthy controls using the pol protein. The researchers noted the difficulty in determining prevalence -and that that was not their aim – but thought prevalence in CFS might end up, based on these early results, similar to the WPI – approximately 67%.

      What we have here is a mishmash that indicates how uncertain the science is. Ideally we would want everyone who tested positive for one XMRV protein to test positive for another one. In fact, ultimately, that is how the testing will work – one positive test never denotes a positive; it has to be confirmed by another test. That is clearly not happening yet and a major goal, of course, will be to tighten up the tests so that consistent results are found across all of them.

      They do suggest that B-lymphocytes could be a reservoir for XMRV; ie a place where XMRV is replicating more (or rather is actually replicating) and, in which, it is easier to find- which would be a really significant finding; however, the initial report stated the XMRV was found in very low amounts.

      The most important to take away from this effort, though, is that the Spanish researchers have been able to find XMRV and they have found it in B Lymphocytes – an intriguing cell with the success of a small Rituximab trial and the herpesvirus infections found in some people with ME/CFS.

      XMRV in Lymphoid Tissue in Macaques - They also showed XMRV can grow in the lymphoid tissue of Macaques . Lymph tissue is an area Dr. Mikovits has speculated could emerge as a reservoir ie a site of increased XMRV replication. That isn’t clear yet but the Spanish team did report that was no evidence that XMRV’s presence there was resulting in the deaths of immune cells -or altering immune functioning. Viruses often replicate furiously inside a cell, kill it and then swarm to the next one…Or the immune system recognizes an infected cell and responds to it. Neither of these scenario’s showed up in this early look at lymph tissues of macaques.

      FunctionalityThe researchers did note, though, that XMRV could be interfering with cell functionality which actually fits in very well with ME/CFS. Immune cell numbers and composition do not appear to be radically affected in CFS – The Klimas/Fletcher studies, on the other hand, suggest that, cell functionality is quite impaired in NK cells and possibly T-cells which could be explained, on e would think, by a kind of smoldering infection characterized by low rates of replication. (Nothing seems to come easy in CFS….plummeting cell numbers aka AIDS would have quickly convinced researchers of the immune dysfunction in the disorder – and quite a few studies have been done – and they have never really shown up…Instead, impaired cell functionality has shown up – a much more difficult and subtle factor to spot.)

    • Huber and McClure Studies On Their Way - It almost seems like every upturn for XMRV is immediately followed by a downturn. Both Dr. Huber’s and Dr. McClure study – both of which are focusing on contamination – will reportedly be published in the near future.
    • A Still Missing Piece – the Alter/Lo Work - The sequencing work Dr’s Alter/Lo are doing will be very important
      given how critical their study was for XMRV. Further sequencing will nail down, presumably for good, where the genetic sequences they found came from. Dr. LeGrice reported that the sequencing would be ‘easy’ but he didn’t state how long it will take.
      Completely sequencing the virus was an important part of the WPI’s study. Shortly, hopefully we will get a definitive report
      on where the sequences they found came from; mouse or man?

    Dec 9th

    • The Buzz From Spain – Cristina Montane relayed a report from Dr. Julia Blanco on the meeting. Dr. Blanco
      first noted the usual on XMRV: that the problematic methodologies being used impair detection, contamination could be possible for some results, the polytropic MLV findings and the need to assess anti-retroviral effectiveness. 

      (editorial) With regards to contamination effecting some findings ….with roughly the same percentage of positives
      in people with CFS and healthy controls showing up in Dr. Cheney’s patients and the London study and the reduced levels of positives
      in theVIP Dx results – it seems hard to believe that this statement applies to the WPI/VIP Dx findings. On the other hand it’s hard to
      understand how a small Research lab in Reno Nevada would be able to stump much bigger and presumably more sophisticated labs
      and there have been a bunch – from BSRI to the Koch Institute to the CDC’s HIV Labs…. XMRV remains a conundrum.
      The NCI’s request that researchers give details that usually don’t make it into their methods section suggests they believe the problem
      is more than not following the WPI’s techniques….We await Dr. Singh’s results in particular given the care she had given it…
      using a PCR technique that seems almost immune to contamination…with the same blood storage and sampling techniques used for
      both healthy controls…and its overlapping checks…and, of course her experience with these pathogens.

      Finding XMRV! After a rather strange sounding statement which seemed to indicate that they were now stating their
      results: “Considering the evaluation of our data set in the context of the knowledge we have of other retrovirus, we can point out” they then noted that
      ” XMRV sequences can be found in patients with CFS but also in healthy donors or HIV+ patients. The copy numbers appear to be
      very low, and their pathogenic potential is unknown”
      which suggests, since no one to my knowledge has found XMRV in people with
      HIV, that they have looked at three groups; CFS, HIV positive and healthy controls and found XMRV in each of them – a big step
      forward.
      Simply finding XMRV is quite an accomplishment given all the zero/zero studies.

      What we don’t know, of course, is what the prevalence was – an important issue! If its high in people with ME/CFS and low in health controls then we’ll another strong result. In any case they are finding XMRV and one wonders if the reason they are finding it has anything to do with Dr. Mikovits earlier trip to Spain reportedly coach a lab there on how to find the virus.

      Very Rare - they also report that when they found XMRV they found it in low numbers, which, in a way is encouraging as well, since that is what we would expect.

      Immune Findings Dr. Blanco reported the Spanish researchers also found alterations in B, NK and T cells. Since NK cell dysfunction is basically expected in ME/CFS, the focus here might be on those B
      and T cells. Any unusual T-cell finding would be a significant development given the key, key role they play in the immune response.
      A B cell finding would be very interesting as well given that a small Norway study has found that Rituximab – a B-cell depleting
      monoclonal antibody – has been quite effective in some people with CFS. A paper on that with an interview with the study director, Dr. Olaf, will appear shortly on Phoenix Rising.

    • Dr. Judy Mikovits Speaks – on XMRV, ME/CFS, MS, Lyme Disease, Cancer…….(is that all???). – The WPI has kind of been playing it safe it seems…but no longer…
      Dr. Mikovits is going to broaden the discussion on XMRV just a little bit in Santa Rosa, Ca on Jan 17th when she talks on it’s relationship to MS, Lyme disease
      and presumably other types of
      cancer than prostate cancer….Early on we heard about XMRV’s possible relationship to autism and atypical MS- which was later described
      as something of mistake…If the report is correct Dr. Mikovits is going to open that discussion again. One wonders if a new
      paper is in the works (except we hear that Journals will not accept XMRV papers from the WPI until their findings have been completely
      validated). 

      The study of note with regard to ‘other diseases’ is, of course, the Singh autopsy study….which should tell us just where XMRV
      is found in the general population and should shed some light on its pathogenicity. If XMRV shows up in the brains of people with encephalopathy
      or in the breast tissues of people who died of breast cancer…..then it’s hard to imagine the wheels won’t really come off on XMRV research

      …This interesting meeting will take place from 2-5 pm

    • News From Spain On XMRV and CFS – Tomorrow! - Clara Valverde on behalf of the Spanish CFS League posted an announcement stating that Spanish researchers will
      announce their XMRV results tomorrow. When we last heard from Spain, Dr Montoya – an infectious disease specialist in Stanford, who has been involved in several ME/CFS studies and is currently collaborating with Dr. Lipkin on a pathology study, was in town to talk with Spanish retrovirologists. At that time the XMRV study was still underway but it appears they have some concrete news to announce. 

      Big Immune Finding - perhaps almost as importantly they will announce the finding of an immune deficiency in cytotoxic T-cells (CD 8) in CFS. This could be big news. Right now there is abundant evidence of problems with NK cells in CFS but NK cells, which Dr. Klimas described as a primitive form of a CD 8 cell, simply don’t get the respect that cytotoxic T-cells do. Finding an abnormality in one of the recognized heavy hitters of the immune system would be a huge win if it was validated. Dr. Klimas has stated that she’s found reduced perforin levels in cytotoxic T-cells and she’s reportedly been working to validate cytotoxic -C problems in CFS but this would be the first official announcement by a researcher. If validated it might very well turn many immunologists heads – causing many to take new look at ME/CFS.

      The researchers will also suggest ways to cope with this newly discovered immune deficiency as treatments are being developed. Spain will definitely be in the ME/CFS spotlight tomorrow!

    • Of Mice Men and MLV-s - With no less than four XMLV publications under her belt during the last 14 months Kozak
      is the premier XMRV evolutionary biologist. Her latest paper is a review of her and others work on murine leukemia retrovirus (MLV)
      evolution that delineates where contamination could come from and where it could not come from. You can find it on the Front Page of
      the Forums (links are not working today).
    • Tripping Up XMRV Too Completely? (from the abstract)- Dr. Bogard from Duke
      penned a paper stating that, to put it bluntly, XMRV gets it’s butt kicked by the APOBEC 3G enzyme found in most of our cells
      and that’s something of problem because if its getting knocked down in most areas of the body it becomes difficult to figure out how it is causing damage.
      XMRV does appears to be more active in prostate cells that do not carry this enzyme and it is apparently these types of cells where XMRV
      could do its work.) The authors also assert that if XMRV or other MLV’s had been active in human cells for long that over time they would have
      evolved resistance to these enzymes – just as HIV has. In short they appear to be suggesting XMRV is a new entrant to humans and because of
      that it’s largely being bottled up effectively in many of our cells by our innate antiviral defenses. XMRV may very well be causing a problem in CFS
      but if it is it’s because it’s replicating in a still unidentified other cell in another part of the body.
    • Six Days to BWG Committee Meeting (and answers for Phase II of the study? - Dr. Mikovits reported the BWG was trying to finish up
      Phase II by the next BWG meeting…hopefully by then we will have a report on their findings regarding the sampling/storage/contaminatiion issues

    Dec 3rd

    • American Red Cross Says No to Possibly Dangerous ME/CFS Blood - Citing recent studies suggesting that XMRV may, in fact, really be present in CFS, the American Red Cross banned people with ME/CFS from donating blood. Why does a Red Cross ban of CFS blood make the newspapers? Because, as the Red Cross website puts it “Some four million people give blood—the gift of life—through the Red Cross, making it the largest supplier of blood and blood products in the United States.” The Red The Red Cross Band leaves the FDA and the American Association of Blood Banks (AABB) looking a little isolated, what with Canada, Australia the UK and now the biggest single blood donation organization in the US, all turning their thumbs down on the prospects of people with CFS giving blood. 

      The Red Cross cited the AABB’s ‘active’ discouragement of people with CFS giving blood by asking people with CFS who are not
      ‘feeling well’ that day not to give blood but went further, stating that ‘in the interest of patient and donor safety” they will ‘indefinitely defer’
      anybody who has been diagnosed with chronic fatigue syndrome.

      However the Red Cross will not specifically ask people if they have CFS; instead, if during the general health questioning, if the donor volunteers
      that they have CFS, they will not be allowed to give blood (thanks to Jennie Spotila for the clarification). No group in the US has taken the
      apparently extreme step of actually asking their blood donors if they have been diagnosed with CFS.

      Patient Campaign to Stop Blood Donations….Just Revved Up…hmmm – The Press Release came just a couple of
      days after a new patient protest campaignfocusing on getting,
      ahem, the Red Cross and the FDA to ban blood from ME/CFS patients got started.
      Rivka reported that the Red Cross told her the
      decision was made
      in October….(but it took a while to write the press release? Whatever happened
      patient action does help. Check out Rivka doing some action of her own in the front of the Red Cross
      Building in the campaign video.

    • All the Study Data Fit to Print – the FDA has
      released a nice chart of all the published and conference study data on XMRV prevalence. The chart provides
      the area study originated from, the type of samples used, the results and the methods used. Thus far, according to
      the chart 6 of 13 prostate cancer and six of 14 CFS studies studies have been positive. It does not include some studies
      that haven’t made it to the conferences such as the Joliceur study. It does include the Cheney study (even
      if they spelled Cheny wrong). The ratio of positive studies drops a bit as they move into other
      disorders (2/7) five of which were HIV studies. Except for a few studies with almost 0 results the same ‘find it or not’ pattern
      prevails with researchers finding XMRV in both healthy controls and patients or not at all.

    Nov 28th

    • Dr. Cheney Reports - in his latest newsletter – or at least that part of which is available for free – Dr. Cheney reports
      news on the serology tests emanating from VIP Dx. Earlier Dr. Mikovits noted that antibody tests picked up more positives than PCR tests. 

      Dr. Cheney noted that 2 out of the three people who tested negative by PCR later tested positive by antibody tests. Overall 83%
      of his 47 patients have tested positive. He expects the percentage to rise to 90% when all the serology results are in – putting the number right about where Annette Whittemore suggested when XMRV broke. It appears from his numbers that the antibody test may add maybe another 10-15% to the percentage of positives.

      Rather startlingly Dr. Cheney reports that 60% of family members without CFS also tested positive but the numbers tested were very low (10 ) and therefore could change dramatically. Nevertheless, if they are ultimately validated, they would indicate that XMRV is quite infectious – not a surprising finding given the mostly anecdotal evidence to date; XMRV appears to be a more robust virus than HIV and may be able to survive in the saliva and semen and cervical fluid.

      How odd it is, though, that the positive rates VIP Dx reported in its testing of putative CFS patients -
      somehow around 50% as I remember- are lower than Dr. Cheney appears to be finding in family members and exposed
      controls without CFS (but perhaps with other problems)…or maybe it isn’t ‘CFS’ being such a vague category. Dr. Komaroff reported recently that
      a significant percentage of people diagnosed with CFS by primary care doctors don’t appear to have it – thus a certain portion of people that the VIP Dx
      may not have ‘it’ whatever it is :) . In any case, the high rates of XMRV postive
      patients in Dr. Cheney’s practice vs the lower rates in VIP Dx at large are yet another small but perhaps telling validation of the WPI’s initial results because
      if XMRV is a more or less ‘CFS-centric’ bug then we would expect higher rates in Dr. Cheney’s practice than in other practices that do not focus on CFS.

      What we don’t know, from this short excerpt, is what Dr. Cheney or VIP Dx considers a positive antibody result. When you get to the level of clinical testing – a single positive result is never considered determinative – it’s always backed up another positive test. Dr. Singh in her patent application requires two positive antibody tests for a sample to be considered positive. Determining what combination of tests will, in the end, constitute a true positive is a thorny issue, one that the BWG will have to grapple with at some point.

    • Blood Working Group Meeting - Put it on your calendar – Dec 14th/15 – Dr. Mikovits said the BWG hoped to be complete with Phase II by this meeting. Hopefully they’ll be able to meet this target.The Group put together a summary of Workshop that included sections on both the positive negative studies and which included this interesting line….” In contrast to the previously reported findings of close genetic relatedness of all XMRVs in patients with CFS and in PC from different geographic regions the amplified gag gene sequences revealed a genetically diverse group of MLV-related viruses” How odd that the more widespread group had less genetic variability than the localized group….It’s another XMRV oddity, for sure, which presumably has something to do with the different testing methodologies.

      In any case the BWG appears to have fully incorporated the Alter/Lo and Hansen studies into their protocols – they are now looking for MLV’s -not simply XMRV.

      They are, of course, not alone – the Alter/Lo paper shifted the ground on XMRV – Dr. Mikovits Dec 2nd talk in Norway (what a pleasant place to visit in Dec!) will be on ““XMRV and other MLV’s in ME/CFS”.

      The BWG’s conclusion was that everything’s is about as clear as mud – but! – we are working on it.. “The science of MLV related viruses in humans is still evolving. While many laboratories have detected MLV-related sequences in prostate cancer samples, others have not. The frequency of positive samples varies widely between laboratories. There is controversy about the detection of MLV-related sequences in CFS with the majority of laboratories failing to detect MLV sequences. There are ongoing studies to determine whether technical issues, such as extraction methods or primers and/or subject selection including clinical criteria and geographic issues might influence the detection of MLV sequences.”

      Of course we expect clarity and are disappointed (and worried) and if its not forthcoming. In a recent Newsweek article Dr.. William Schnaffner, an infectious disease specialist, suggested that we should neither expect clarity at this point or be disappointed that it has not appeared ““Cutting-edge science is often not definitive,” says Dr. William Schaffner, an infectious-disease expert at Vanderbilt University School of Medicine. “Keep your seat belts tight.”

    • That Newsweek Article - is empathetic and well-written and well worth reading. In it Dr. Andrew Mason, after referring to the battle over decades long battle over the cause of ulcers, argues that anti-retroviral trials are the ‘the only way to win this battle’. Dr. Lipkin would not agree stating “Patients are clearly ill and suffering, and we need to address treatment as rapidly as we can. But the first order of business is to determine if the association is real.” Dr. Lipkin is clearly intrigued by ME/CFS – he is engaged in two studies – but it took the NIH almost a year to get his study off the ground – hardly a sign that they’ve been working as rapidly as possible. Still, when they did get into gear they did so in big way – hiring one of the top pathogen detectives to lead the search. 
    • Dr. Deckoff Reports – http://treatingxmrv.blogspot.com/ – meanwhile Dr. Deckoff and her daughter continue to slowly improve. It’s not dramatic..it’s slow drips over time that she notices over the months rather than the days. They are charting functionality using the Karnovsky Index and both have pushed past 80 for the first time. One of the surprising benefits for her has been a reduction in peripheral neuropathy (nerve pain) that can be very painful.
    • Test Results - meanwhile there have been a flurry of test results on the Forums. Several people received positive results by culture and negative results by serology at VIP Dx – rather the opposite of what one might expect at first – but perhaps suggesting a poor immune response to the virus (or an antibody test that needs some improvement). Another person with milder CFS (myself) tested positive by culture (it took a long culture) – suggesting that viral loads were really low and I but had a strong antibody test – which I was told could be protective (which might be why viral loads are so low???). I had gradual onset and Dr. Mikovits noted that others with gradual onset have tested positive. There appear to be several different variations and the science, of course, is still evolving…… One of Dr. Peterson’s patients who tested positive by WPI tested negative by Dr Jay Levy – a virologist who was associated with CFS in the early days.

    • The Singh XMRV Patent – The Next Cancer for XMRV? Breast Cancer, Prostate Cancer Results Validated….CFS still Unclear The Next Cancer for XMRV? – JMK on the MECFS Forums snuffed out Dr. Singh’s XMRV patent application and then XMRV Global Action highlighted the most relevant sections and here we are with what is easily the most exciting news for XMRV since the Science paper was published in October of last year. The patent application states Dr. Singh has found XMRV in 25% of 178 samples from patients with breast cancer – a finding that will surely send a shock through Cancer research community. Tellingly, XMRV was not found in the tissues just surrounding the cancer as originally appeared with prostate cancer – it was found smack dab in the middle of the malignant breast tissues.

      Hormones plays a role in many cancers including prostate and some breast cancers…is XMRV, which we know has a hormonal connection, zeroing in on hormone related cancers? Studies change the course of research efforts not patent application but it’s a patent application from a respected and careful researcher and you can bet your boots several papers on their way….

      Prostate Cancer Clarified - breast cancer wasn’t the only cancer to get a big hit. The XMRV prostate cancer connection has been questioned because of the inability, thus far, to find XMRV in the malignant tissues themselves – it’s always been found in the tissues just surrounding those tissues but no longer; the application, rather startling, stated that these new immunohistochemistry and antibody results indicate XMRV is overwhelmingly found in the malignant epithelial tissues in prostate cancer patients. If validated, this will, undoubtedly ramp up XMRV cancer research efforts.

      Happily the antibody (30%) and immunohistochemistry (27%) results correlated very nicely – thus providing an important check on their validity. The immunohistochemistry staining also revealed a telling pattern of XMR positive cells clustered together – just as you would expect with a virus.

      Still an Underestimate – interestingly Dr. Singh believes her tests still underestimate the prevalence of XMRV in prostate cancer because it’s found in such a small subset of cells and that a closer examination of the tissues. will most likely lead to increased prevalence rates. Viral load is believed to be very low, in fact, she believes it is “close to the detection limit of the qPCR’ assay.

      She doesn’t appear to have much doubt about the potential virulence of the pathogen, though; her results showed that XMRV presence was a correlated with cancer severity; that is, the more severe the cancer the more likely it was that XMRV was found in it.

      More Cancers?/More Tissues? - Findings of other cancers were not detailed but the application does appear to indicate (?) XMRV was found in
      immune cells in the lymph nodes, the bone marrow and peripheral blood from hematological malignancies as well as the testes. (This is in a section that lists ‘embodiments’ of the present methods). Hematological malignancies refers to cancers that affect blood, bone marrow and lymph nodes and include such cancers as leukemias and non-Hodgkin’s (and other) lymphomas. Non-Hodgkins Lymphomas are reportedly found in 5% percent of Dr. Peterson’s Nevada cohort.

      The immune cells in the lymph nodes could be very telling as the lymph nodes are a reservoir for many infections. It seems likely that these results could reflect the autopsy work Dr. Singh has been doing. On the other hand, the application did state that the only other tissue XMRV was found in the 8 prostate cancer patients she autopsied was the testes.

      XMRV Clarified - Dr. Singh has gone a long way in refining her techniques to find the virus. First she generated a new infectious clone called pXMRV33 constructed from two overlapping clones. She transfected some cells with her clones and nine weeks later began to detect reverse transcriptase – an enzyme associated with retroviruses. She then took the supernatant (cell free material), dropped some cells in it and then was able to detect retroviral activity in cells – indicating she had an infectious retrovirus on her hands.

      Electron Microscopy -looking through an electron microscope she was able to see abundant viral particles that resembled a murine retrovirus.

      Antibodies – she was able to find antibodies specific to XMRV by affecting rabbits with it and then doing Western blot tests. She found that (except for the env proteins) the amino acids in the proteins associated with XMRV were very similar (90%) to those in the Moloney murine retrovirus she’s been studying for quite some time.

      It appears that she has replicated several important aspects of the WPI study and in at least one way has added to it; she has demonstrated that she has an infectious virus, she has created PCR and antibody tests whose results, at least in prostate cancer tissues, correlate with each and her electron microscopy results suggest she has a MLV-like retrovirus. Plus her immunohistochemistry test provides a newway to validate her results.

      XMRV In Fluids
      Dr. Singh has also refined her testing protocols for many of the bodily fluids. The application states that her immunohistochemistry assay, in fact, can be used to
      detect XMRV in saliva, semen, peritoneal fluid, synovial fluid, prostatic or cervical secretions, blood and serum. It describes a specific method for finding XMR in
      cervical fluid – and notes that the potential for spread from mother to child via that means.

      Semen Findings Validate WPI Findings for Healthy Controls - – The XMRV in semen finding had important implications because XMRV showed up in the semen in exactly the same percentage (7%) of healthy controls as tested positive in the original Science study
      - a very nice validation of the WPI’s original findings. Dr. Mikovits long ago, if I remember correctly, stated XMRV was found in the semen but Dr. Singh is the first
      researcher, I believe to validate Dr. Mikovits statement. The semen, of course, have significant implications for the possibility of transmission.

      Chronic Fatigue Syndrome - The juice seemed to run out a bit when it came to ME/CFS, however. She has definitely made progress; the application states
      2 XMRV antibodies have been found in a CFS patient and that most of the ‘non-reactive’ samples came from the healthy controls.
      Dr Singh also knows which XMRV antibodies to test for (SU, p15E) and which ones not to test for (CA – found in healthy people as well). We can guess that XMRV showed up more consistently in CFS patients than in the healthy controls – a nice start! – but we don’t have any idea of what percentage of people with CFS she found it. It looks like
      we will have to wait for her paper for that.

    • DecemberDate for Phase II? – I asked Dr. Mikovits when she expected the Phase II of the Blood Working
      Groups effort to be complete? She said they hoped it would be complete by the next meeting of the
      Blood Advisory Groups – which is Dec. 14th
    • The Race Is On - In her latest blog Amy Dockser Marcus states that researchers are ‘racing’ to develop
      tests for XMRV.

      Abbot Diagnostics, Gen Probe and Roche Diagnostics are hard at work and Roche says it believes it will have a
      test for researchers available in months. Gen Probe, on the other hand, is developing a test to detect an early warning
      XMRV test that can find XMRV after infection but before the immune system starts producing antibodies. The Cleveland Clinic,
      meanwhile, is developing a test that can find XMRV in the urine. 

      To get beyond the ‘positive specimen controversy’ that cropped up when
      the CDC was unable to find XMRV even in the samples the WPI had stated for positive, researchers at Abbott, Cleveland
      Clinic (which was part of the original study…) and Emory University are creating positive samples by infecting
      monkeys with XMRV.

      The Antibody Tests Antibody test development is a hot item. Abbott, Cleveland
      Clinic and Emory together and Dr. Singh, working at ARUP labs, have each developed antibodies to three proteins
      on the virus. Dr. Bagni at the NCI has developed a test that is deemed positive if it reacts with (yes) three
      antibodies. (A positive result to an antibody test often requires that a person test positive to
      more than one antibody).

      Now all they need to do is find it in ME/CFS.

    • Unbroken – the Louis Zamperini and
      Laura Hillenbrand Story
      - no it’s not about XMRV but it is about Lauren
      Hillenbrand and that means CFS. She is a great spokeswoman for CFS and Louis Zamperini was a great vehicle for her
      next book, seven years in the making and which she says both brought her life and cost her physically.
    • A Mouse Model for XMRV – And now to one of the more interesting twists – developing a mouse model
      for an er…mouse derived virus? Of course we now know that XMRV does not appear to be found in the mice much
      (if at all) either in the wild or in the lab (which does kind of make one wonder how it managed to contaminate
      the WPI’s samples……if the worry was contamination from lab mice and it’s not actually in lab mice….then how did it???? Never mind)… the key
      with this study is that researchers have found a mice they can manage to infect XMRV with (it wasn’t easy),
      and now that they can do that they can make them ill, probe them, dissect them, feed them drugs, whatever….essentially the way
      is clear for the magnificent animal research establishment
      to go to town. 

      Thus far they’ve found XMRV in the spleen (expected immune organ), the blood (naturally) and the
      brain (most interesting)..(If mice have prostate glands and it was found in them they didn’t (perhaps out of respect for
      their privacy) report it was found there). The mice did recognize XMRV as something not good and did amount an
      immune response to it. Like humans their immune cells were able to knock it down with their all purpose XMRV
      transfiguring APOBEC enzyme…and that was that…..Now about those brain cells……where and what kind???

    • Dr Enlander Talks – Dr. Enlanders comments on the muddled state of XMRV thus far.First he provides an insiders view
      on what we can now see was a very hastily done first followup study that appears to have broken speed records for study
      approval, completion and publication (thus implicating an nice swath of the UK CFS medical establishment in a rush to judgment…
      wouldn’t they have been smarter just to wait a month or two? Somehow they didn’t mind that everyone
      else would be agog at their ability to manipulate the process -which, come to think of it, may be the most telling
      thing – that they just
      didn’t mind ….Where would we be without the British?
      :) ).

      He notes the both the differences and the close association between XMRV and the
      MLV’s found in the Alter study – a tricky and still unresolved subject and notes some shortcomings on the pro-XMRV side; despite it’s
      strong points

      the first study had some of its own, ahhh, issues (and how unbelievable is it that here we are, a year later, talking about the
      first study….) and the WPI’s
      lack of receptivity for whatever reason (and we have no idea, so let’s not even speculate) regarding his own proposed double-blinded XMRV study.
      He ends by
      noting something most ME specialists (and all patients) would probably agree with “All of us would love to initiate treatment’ – and let’s leave it at that.
      He is reportedly currently
      at work on a double-blinded XMRV study using multiple labs.


      “I was asked to comment on the XMRV research.
      In Oct 2009 a virtually unknown Institute in Reno, Nevada, the Whitmore Peterson Institute, published in Science exciting
      research in which they claimed to have discovered a new relationship between the XMRV virus and CFS/ME.
      This was exciting news, we hoped it was the initial foundation of proof, that CFS/ME was a physical disease.Within 6-8 weeks, miraculously, papers were in publication denying the original research. Usually it takes my Medical
      Center several weeks to allow a research proposal to proceed, followed by several weeks or months for the research to be
      completed and then several weeks or months for journal acceptance and publication. So I was astounded, as were others,
      at the time frame of the response, the journals and the relationships of the publishing research centers.
      Then a virtual boxing match occurred. This was to the detriment of all. One institute claimed poor cohort selection,
      another bad specimen handling, another claim related to lab contamination , stale samples that were stored for years,
      one even blamed the Chinese company that made the specimen tubes and so the complaints and cross complaints mounted.
      Harvey Alter, a research physician at NIH of ultimate repute, showed that indeed there was a MLV virus in CFS/ME specimens.
      This was countered by statement that MLV did not replicate the XMRV virus research. In essence this is true but
      the MLV virus and the XMRV virus has similar virion particles and/or cross reaction. Instead of certain research
      workers blasting this difference, it would have been opportune to investigate the relevance of the presence of either
      of these virions.

      Both the protagonists and antagonists are not flawless. The initial research was not replicated in
      a double blind, multiple lab replicate study by independent selection.
      I offered, Whitmore Peterson, an independent replicate study of carefully selected Fukuda/Canadian criteria
      patients and controls between five viral labs. They were not interested. The whole matter of this research is
      puzzling, agenda seems to overpower the research . All of us would love to initiate treatment, if indeed the virus was causal and if the treatment neutralized the virus. Lab research into non toxic neutralization in cell culture is incomplete and must be performed prior to using toxic anti-retrovirus treatment in patients. Action against XMRV should be explored in vitro of existing non toxic anti-CFS/ME methods viz; Ampligen, Kutapressin, Nexavir, Hepapressin, isoprinosin etc.
      In future I hope to see a united effort in exploring this devastating disease rather than a continuous boxing match- news that even our Utah XMRV/MLV expert was finding XMRV more complicated than expected

    • Amy Dockser Marcus recently told us that Dr. Lipkin called together representatives to discuss his study about 2 weeks ago.
      Now we’re getting a few telling details – or rather we can infer a few telling details. She notes that clinicians from Miami,
      Boston, Palo Alto and Salt Lake City will be involved which can only translate to four of our top physicians: Dr. Klimas, Dr. Komarroff,
      Dr. Montoya and Dr. Bateman. (Do you think they know a person with CFS when they see one?) 

      Dr. Lipkin will be taking a broad sweep
      of the viruses – looking for XMRV and all over viruses in the same family. Patients will have to meet two criteria, which
      given the physicians involved, can only mean the Fukuda AND the Canadian Criteria PLUS they will have to have
      infectious onset which means the patient cohort will closely duplicate the original patient cohort in the Science study – which is,
      of course, what we want. Three labs will test the blood -the WPI, the FDA/NIH (Alter/Lo) and the CDC.

      ME/CFS experts providing ‘good’ ME/CFS patients
      and using two of the only labs to actually find XMRV? This looks like an excellent study.

      Now how about a timeline?? :) :)

    • It’s Not a Passenger Virus? – I missed it but Dr. Vernon’s take in the last CFIDS ELINK was intriguing. She wrote ”
      Possibilities for XMRV being opportunistic or a passenger virus seem to be narrowing based on the negative
      results in cohorts of patients with immune suppression, immune activation or blood-borne infections”. What an interesting
      statement this…..and it makes sense – if XMRV is not in patients with immune suppression then it’s not likely to be a
      passenger virus in CFS either is it? (This conclusion, of course, requires that HIV/AIDS researchers are looking for it correctly).
      If Dr Vernon is right, then if XMRV is found in ME/CFS then it is exploiting some sort of abnormality unique to it – which brings
      up the possibility of having a retrovirus found in CFS, Fibromyalgia, autism, etc….but not in immunocompromised AIDS patients
      which would very be different indeed.

    • No Surprise – news that even our Utah XMRV/MLV expert was finding XMRV more complicated than expected
      probably should have come as no surprise…broken timelines have been maybe the most consistent thing we’ve been
      able to observe with XMRV. Consider these 

      (*)WPI, with Glaxo Smith Kline reportedly on board, was reported to expect treatment trials to begin within six months of the Science publication.

      (*)At the CFSAC meeting late last year Dr. Coffin thought we’d have the answer ‘within six months’

      (*)The antibody tests were promised and promised….but eventually they did arrive (so there’s hope :) )

      (*)The WPI started with one set of methods in the Science paper and then brought forth an improved set about five months later

      (*)Dr. Singh’s study is taking a bit longer than expected because – a PR Forum member was just told -it’s more complicated than expected

      (*)Dr LeGrice and Dr. Glynnis just a month ago thought Phase II would wrap up about 10 days ago….

      Who wants to bet on Phase III being wrapped by New Years? XMRV is clearly complicated. It’s definitely past time to stop expecting anything to happen on a
      timeline. All we know for sure is that the results won’t be done until they are done – and not a second before.

    • International Conference
      Rita on the PR Forums somehow found some interesting XMRV abstracts in the 11 Symposium on Antiviral Drug Resistance – demonstrating
      again that XMRV is getting in anywhere it can. 

      XMRV in Immune Cells - One from the National Cancer Institute sought to explain an interesting dilemma – research done after the
      WPI’s Science paper indicates that XMRV is basically knocked down and rendered non-infectious by the APOBEC3 enzyme in the immune cells in the blood
      the WPI found it in. (The amino acids the enzyme replaces in XMRV makes it impossible for XMRV to replicate.) Yet after digging
      XMRV out of these immune cells the WPI was able to grow the virus and replicate it! If that enzyme had rendered XMRV inert,
      so to speak, how was the WPI able to get it to replicate again? These researchers found that XMRV could replicate in PBMC’s
      only if the APOBEC enzyme was inactivated. However, if they cultured the cells with ‘canine indicator cells’ they could recover
      infectious virus. This suggests to me, a laymen, way in over his head, that there are substances that can help XMRV bypass the
      APOBEC3 enzyme.

      However, these researchers suggested that this does not happen in the blood in the body, and that
      at least as regards replication, the immune cells tested thus far
      are essentially a dead end for XMRV. (Hence the search for a different viral reservoir)

      One of the most interesting part of this study was the ease with which they did it. They simply infected
      cells with XMRV and monitored virus production using quantitative PCR. It’s clearly much easier to purposefully infect
      cells and then detect the virus again than it is to find it in the blood.

      Dr Coffin Gets Down to Work! – Dr. Coffin’s at Tufts and the National
      Cancer Institute (again) have been taking on one of
      thorniest problems – how to distinguish XMRV from mouse DNA or from an endogenous retrovirus.

      An endogenous retrovirus
      is a retrovirus that, sometime in the distant past, inserted parts of itself into the genome of an organism.
      The genomes of inbred mice in labs, in particular,
      are swarming with degraded non-infectious MLV gene sequences. The right bit of mouse DNA contaminating a sample could,therefore, look like
      XMRV. The WPI was able to isolate the whole virus – indicating they did not discover an endogenous retrovirus – but no one
      else has.

      A very specific PCR assay Dr Coffin developed for XMRV has not found it all in inbred or wild mice – suggesting, as Dr. Mikovits
      reported, that it is unique to humans. They developed another assay that distinguishes between XMRV and endogenous MLV retroviruses – thus
      enabling them to quickly tell if a gene sequence belongs to XMRV, an endogenous retrovirus or from mouse DNA. Plus
      they’ve developed another PCR assay that focuses on mouse ‘DAN’ contamination.

      It appears that researchers are becoming
      ever more effective at determining when an XMRV result is real and when it actually reflects something else. These tests will be
      be very helpful (a) to researchers such as Dr. Alter and Dr. Hansen who have found gene sequences that are XMRV-like but
      have pMLV characteristics and (b) to clearing up the contamination question. Basically it appears Dr. Coffin now knows XMRV when he finds
      it.

    • Some Light on the Singh Study – the Singh study is big (@100 patients) and comprehensive – besides doing culturing Dr. Singh
      she is using two kinds of PCR and for viral RNA and presumably an antibody test. The blood storage, etc. protocols
      are the same in both the healthy controls and patientsAND they are all from one area (no geographic sequence
      variation). Plus Dr. Singh has been studying XMRV and MLV’s for years. In short it’s quite an
      important study. 

      Slippery Beast – I asked Dr. Light, one of the principals in
      the study, if there was anything he could say about it? He reported they just had a meeting – they think the are,
      as he put, ‘finally getting a handle on it’ but are still not sure – and they didn’t want to build up hopes
      one way or the other. He hopes they’ll have something definitive to report soon.

      XMRV, no surprise, given the ups and downs of the past year,
      has been a bit slippery. The Singh study began early this year – it’s probably somewhere in
      its 7 or 8th month now. One grace of Dr. Singh’s study (and a complicating factor) is its complexity; she will
      want the results of the different tests (2 PCR’s, RNA, culture (and antibody?)) to agree – not an
      easy task with a relatively new virus. Of course, when the different
      tests do all agree then you have a really solid result.
      For more on her study click here.

      XMRV is certainly in good hands; Dr. Singh is pushing the field forward in several ways. She has developed
      an antibody test and her own XMRV clone and, of course, is a key player in the XMRV prostate
      cancer hunt.

      reluctance to keep a ME/CFS Community, that’s sitting on the edge of its collective seat,
      of the progress of their work, now have a place to go. Otis on the PR Forums has created a nice
      advocacy
      website with names and numbers to email. The BWG may not be able to release the
      results now but they can certainly be more forthcoming. Check it out here

    Nov 15th

    • Blood Working Group Responds – A Little - almost a week after emails were sent out requesting the status of the BWG’s findings
      Dr. Holmberg, the co-chair of the group, did respond. After a rather pro-forma beginning – this is what we’ve done – see how public we’ve
      been thus far, he ended with a pro forma response – Phase II is not done yet. 

      Thank you for your inquiry regarding the activities of the Blood XMRV Scientific Working Group
      which was received both by Dr. Glynn and myself. The mission of the Working Group has been reported at several venues.
      The methodical process has been tracked in various phases, phase I-IV. The results of phase I are available and have
      been reported at the first XMRV Retrovirus Workshop (http://www.virology-education.com/index.cfm/t/1st_International_Workshop_on_
      XMRV/vid/1FF10297-0DC4-5841-64634A68A3EC3EF1). Phase II required institutional review board (IRB) approvals and consists of
      pilot studies to evaluate how to best decrease the variability in sample preparation. As a result, Phase II is in progress and
      there are no results to report yet. We will report results when available.

      Is that enough? I don’t think so. Would providing a general timeline be too much? If it’s probably going to take another month or so then
      why not state so and
      let everyone relax? The BWG (and other) federal groups don’t realize how far a little bit of good will goes (or how much frustration has
      built up over the years.) Dr Mangan, the new head of the NIH effort on CFS, God bless him, does get it. Hopefully the BWG will as well

      .Dr. Holmberg
      has been asked to provide a general timeline.

      So what are the facts thus far? We know that on Oct 14th Dr. Glynnis, the co-chair of the Blood Working Group stated that she thought
      the results would be ready in just three weeks. That suggested that the group was, more or less, wrapping things up and that the end
      was in sight. Now they’re about a week overdue – no big deal. A couple of more weeks of no results would suggest, though, that either
      a) the first estimate was never close or b) something unexpected occurred. I would guess B. Dr. LeGrice, after all, gave that same three
      week figure as Dr. Glynnis did and officials associated with the program have been talking about XMAS/New Years as the end date for the NEXT phase.
      Time will tell.

    • The Stars Begin to Align: Good News for the WPI and Other CFS Researchers – a huge hurdle for CFS researchers has somehow recently been removed. After Charlotte and Bob
      somehow dug up the latest Grant review panel (CFS SEP) for CFS (it’s incredibly hard to find) they found, surprise of all surprises, that it not only that
      actually contained mostly CFS researchers but that it contained quite a few contained immunologists/pathologists. 

      The WPI’s difficulties obtaining grants
      aren’t limited to them; many researchers have had difficulty getting their grants funded. One of the big reasons for that
      was a CFS SEP review panel that has over the past decade been dominated by pain and, believe it or not, dental researchers. That has all
      changed; CFS researchers can now look forward to having their grants reviewed by the likes of Dr. Klimas, Dr. Ruscetti and Dr. Friedberg. This should
      mean better grant scores and more funding for CFS! Check it out in The Start Begin to Align for ME/CFS at the NIH

      his daughter has had it for 20 years. In an audio interview Dr. Tate called ME/CFS a ‘devastating disease’ and spoke of his ‘tremendous respect’
      for people fighting the disorder and noted that at one point all his daughter could do was to crawl to the shower.
      He called it a disorder in which the innate immune system is permanently switched on. His daughter came down with ME/CFS after a
      bout with EBV (infectious mononucleosis, glandular fever). He is eagerly awaiting the outcome of XMRV and suggested that the EBV infection could have
      created the environment
      that allowed another virus (such as XMRV?) to enter. (If only he ran the NIH……) Thanks to Overthehills on the PR Forums for digging this up. The CFS

      The Patient Community Twists and Turns and the Blood Working Group Remains Mum
      A month earlier Dr. Glynnis at the CFSAC panel Oct 14th (1:45:28) stated 

      “We hope we’ll be able to have results of this ongoing study by early November and it is our plan certainly to immediately release the results because we think they will be extremely important to the scientific community
      ….so that the optimal preparations of the samples will be known.”

      Amy Dockser Marcus’s blog in the WSJ stating that Dr. Lipkin, who is reportedly going to
      use BWG findings for his study, met with federal officials, researchers and advocacy reps to discuss how his study
      will now proceed, of course, set off a firestorm of speculation. Was the BWG done? Why have a meeting if it wasn’t?
      If it was, why not release the results?

      That the details of that meeting were embargoed meant what? Speculation raged…was this good news or bad news?
      CAA Board Member
      Jennie Spotila was willing to jump in and state that, while she wasn’t privy to all the information, she thought the BWG findings had nothing to do with Lipkin’s
      meeting.

      The only thing certain
      is that the federal officials have once again allowed events
      to spin out of control in the patient community, leading to more and more speculation and, of course, anxiety. The CAA
      is caught in the middle between their promise to keep the information embargoed and a community that would like to
      know what’s going on.

      The BWG could easily clear up the confusion but repeated emails to the BWG co-chairs have been ignored.
      Perhaps the most logical assumption to make at this point is that Dr. Lipkin just happened to call his meeting about the time
      that the BWG was to release their results and that the BWG, as have most groups in the past, is just taking longer than
      expected to finish up their study…..and that they’re simply inept at dealing with a curious and informed patient population.

    - things appear to be going well for Dr. Deckoff-Jones and her daughter, Ali. Eight months into
    their anti-retroviral trial, Dr. Deckoff-Jones reports that that recovery is ‘incomplete’ but their ‘improvement feels pretty solid’ with their
    worst symptoms gone or hugely reduced. Basically she says “its a life”. Ali is taking interest in typical teenage
    girl subjects (she’s writing a post apocalyptic vampire novel). Dr Deckoff says she is ‘living and
    breathing her subject right now’ which taken literally could be a little scary but is another good sign of
    increasaed health.

    Dr. Deckoff-Jones again mentions ‘Actos’ – an anti-inflammatory and glucose metabolism regulator. With the sensitivity to
    sugar and the inflammatory symptoms present in ME/CFS the supplement seems almost like a no brainer. There’s more in the blog on Actos
    and its properties
    l

  • An Antiretroviral Defense Dr. Deckoff Jones linked to Heaven in My Foots well reasoned and quite compelling defense of the use of antiretroviral
    drugs in people with CFS who choose to use them in The Tuskegee Mentality: Condemning Antiretroviral Treatment for Chronic Fatigue
    Syndrome . 
  • Dr. Mikovits UCLA Talk - Dr. Mikovits talked about viral/DNA interaction in ME/CFS stating that she’s identified
    6 DNA defects that could make people with ME/CFS more susceptible to viral invasion – a tack that Ian Lipkin appears to be
    taking with autism; it’s not just the virus – it’s the viral – genome connection that confers disease.

    She reported XMRV
    is more easily detectable in the cell free blood plasma than in PBMC’s. Viruses, of course, infect cells, replicate in them and
    then travel through the plasma looking for more cells to infect.

    In the background info she noted the RNase L and NK cell abnormalities
    in many people with ME/CFS which could decrease their ability to fight off pathogens. (Interestingly, early Dr. Mikovits reported
    that XMRV infection was not associated with either of those measures; instead it was associated with interferon levels. Earlier she also
    reported that she had found an immune signature in XMRV positive patients; that paper will go a long way towards clearing up the
    what immune abnormalities are associated with the infection. However, that paper probably, one would guess, will not get
    published until the research community has come to a consensus on XMRV.

    Dr. Mikovits explication of the MLV’s effects on mice was almost painful in how it closely matches some ideas regarding
    CFS. She noted how MLV’s tend to replicate in the epithelial cells lining the blood vessels in the brain, which activates neuro-glial cells
    causing them to produce pro-inflammatory cytokines resulting in ‘leaky capillaries’, inflammation and neural damage.

    Dr. Baraniuk’s
    fascinating spinal fluid proteome study findings suggested a very similar scenario; increased inflammation (associated with amyloid
    factors) that stick to and puncture blood vessels causing leakage (and more inflammation). There is also intense interest in
    the role neuroglial cells play in producing pain in FM and other mysterious pain disorders. Plus virtually everybody, it seems, is
    interested in the role cytokines produced in the brain play in CFS. Cytokines, for instance, trigger ‘sickness behavior’
    which is nothing more than a weird way to refer to the fatigue, pain and other fluey symptoms associated with colds. Even the CDC
    is very interested in the role Interferon plays in CFS (ironically enough – it’s a cytokine Dr. Mikovits associates with XMRV). So there’s alot
    of potential overlap between the damage Dr. Mikovits reports MLV’s cause and findings in ME/CFS. Thanks to Andrew for providing a friends summary of the event.

    Dr. Baraniuk’s followup brain proteome study is
    finished and my sense, in talking to him, was that results were good’. A validation of his first paper would be a huge win.

      The ‘Big’ (Little?) Lipkin Meeting – did occur. It does appear to have been focused on Dr. Lipkin’s study. Why federal, research and advocacy representatives or invited to it is a question whose answer we will presumably get at some point. Since the Lipkin study is using the Blood Working Groups findings we have to assume that they have come to some conclusion about storage/sample preparation/contamination, etc. yet for some reason we’ve heard nothing as the contents of the meeting have apparently been embargoed…which means what? Big news? A really secretive researcher? Is the BWG waiting for
      the right time (whatever that could be?) Who Knows? The ME/CFS community was promised, however, a quick release to the BWG’s findings – and that has not occurred. 

    • Three compelling fundraising video’s from the Whittemore Peterson Institute. Stating “As far as I’m concerned the WPI brought us out off the darkness into the light” Dr. Jamie Deckoff-Jones at times emotionally relates the difference the WPI has made in her and her daughter’s life using treatments based on the WPI’s XMRV findings.
      Another video features parents of children with a different neurological disease. The last was the most compelling for me; it features a father who
      used the WPI’s technology to find three viruses in his daughter – who almost overnight was able to speak coherently for the first time using antiviral therapy and goes on
      talk about the importance of private funding.
    • Never Easy – The Singh’ Study Proceeds – The Singh/Bateman study appears to have wrapped up but like just about everything else in XMRV the data does not appear to have come easily. Patients were first told to expect results in July/Aug (remember Dr. Bateman’s webinar in which she hoped to be able to present some results?) now it’s November and they’re still waiting.

    Nov 7th

    • Big Meeting? What Big Meeting? On Thurs Amy Dockser Marcus in her blog at the Wall Street Journal
      noted that Dr. Ian Lipkin had convened a meeting of federal, academic and advocacy representatives
      to discuss the next phase of the search for XMRV. Now that the Blood Working Groups findings
      APPARENTLY are in (contamination/no contamination, proper sample preparation and storage) he is due to
      kick off his own study using those findingsl. 

      But why would HE call these
      groups to New York to discuss the ‘next stage’ of the search for XMRV in CF’? He did not produce the findings, nor is he
      slated to lead a broad effort on them – he is, so far as we know, involved in one, admittedly
      quite large and important study, but nevertheless, just one study on XMRV and CFS. So why is HE
      calling these people together? Will a broad new effort take place? What is going on with this
      meeting – that apparently has taken place according to Amy, yet we’ve heard nothing about it. The questions
      abound.
      Like so much else in XMRV the process continues to surprise!

      Can we make anything of the fact that the effort to find XMRV will shift to the ‘next phase’? Does
      this mean they’ve ruled out contamination? It could but it might not as well – it could just mean
      that they feel confident that they know how to search for XMRV now and they are starting afresh and resampling
      or newly sampling people with CFS. The
      definitive assay for XMRV, by the way, is not due until around the New Year – this meeting seems to be
      about the ramifications of the BWG’s findings and gathering samples for the definitive studies.

    • Website Teetering – First the website was down – then it was up but I was unable to publish to it. Now I
      appear to have found backdoor approach to publishing. It may not be pretty but it seems to work and hopefully it will remain open.
    • The Big Headscratcher – Looking back one of the big headscratchers
      for the Blood Working Group must have been the CDC study. It wasn’t the results
      of the study but what preceded it – the CDC’s attempt and inability to find XMRV
      in the XMRV positive samples the WPI sent them prior to the
      publication of the Science paper. ‘Contamination’ seems to be the talk of the
      town in some quarters but if there was a contaminant – either XMRV or something
      bit of mouse DNA – then the CDC should have picked it up using their oh so
      sensitive tests yet they picked up nothing. Dr. Mikovits later said that their
      probe was based on an XMRV clone that had been cobbled together from gene
      sequences found in prostate cancer derived tissues but they also looked at
      broadly conserved sequences for MLV’s and found nothing. Here may be where the
      sample preparation questions began to come into play. It’s possible that those
      samples did contain XMRV when they left the WPI and didn’t when the CDC put them
      into their PCR.

    • Website Knocked Down Temporarily - I wish I could say it was a virus :)
      but it was something much more innocuous.
    • Big Meeting in New York: Take a Deep Breath- XMRV’s Time is Almost Here: – Amy Dockser Marcus reported that “W. Ian Lipkin,
      the Columbia University-based virus
      hunter tasked by the government with resolving some of the XMRV questions, is convening a meeting this week.
      Representatives from HHS and the academic and advocacy communities are in New York to develop a strategy
      for a study to determine whether XMRV is found at higher rates in CFS patients.
      ” Dr. Lipkin is to use the findings from the
      Blood Working Group to inform how he does his own study – but this is apparently bigger than
      a single study. Dr. LeGrice said about three weeks ago that the blood
      storage/contamination issues would be cleared up in three weeks. He was echoed
      by the NHLBI rep in her testimony at the same meeting. Now we have
      representatives from the government, research and advocacy organizations meeting
      sometime this week, which means, given that her blog was on Thursday that it has already
      occurred (?) 
    • Dr. Singh on Detecting XMRV – the title of Dr. Singh’s commentary in the Viruses journal
      went right to the heart of the matter. The problem right now is a simple one;
      “Detecting Retroviral Sequences in Chronic Fatigue Syndrome”. That’s the whole
      ballgame – that’s all that anyone cares about right now – its ALL about
      detection – this was a timely article and it was nice to see someone tackle this
      publically. Dr. Weiss’s Rumor Virus article gave a good historical overview of
      the sometimes extraordinary difficulties pathologists can face now given the
      immensely powerful technology available to them but Dr. Singhs article actually
      delved into the specific issues surrounding XMRV. 

      Splitter or a Lumper? Dr. LeGrice and others looked narrowly at the pMLV finding
      and stated that, until we know more, they should be treated as unrelated finding
      - which has its own logic. Dr. Singh
      took a broader view and stated the opposite; both have their own logic. For Dr
      Singh, considering that the pMLV’s and XMRV share 95% sequence similarity
      sequences, the same receptor and, get this, are actually closer to each other
      than different variants HIV (85-95%), it appeared it was easy for Dr. her to place the pMLV findings by Alter/Lo firmly within the context of the Science papers XMRV finding.
      It’s all about emphasis.

      One Big ‘Happy’ Family? Is Dr. Singh implying these are
      all one family of of viruses that interact with each other like HIV does? Dr.
      Mikovits hinted, if I remember correctly, that more than one type of virus may
      be needed for them to survive in the body and Dr S. Ruscetti is reportedly
      looking at how these viruses combine with each other. There is also section of the pMLV’s that we know can
      jump into other viruses…Are the pMLV’s and mPMV’s and XMRV’s all one family????


      Contamination
      – Dr. Singh felt contamination of the Lo/Alter samples was unlikely because the instruments used to
      search for it were 100 x’s more powerful than those used to look for XMRV and the wide discrepancy in prevalence
      between the healthy controls and CFS patients. She noted, however, that with the exception of the 8 samples
      from present day patients that samples for most of the controls and patients were
      handled differently D) evidence of a replicating virus using antibody tests or actually finding the virus are critical E)
      (The same thing applies for the original Science study)

      The ‘Perfect’ XMRV Study - But how to do a study that helps to clear up the confusion? That, according to
      Dr. Singh is certainly doable (and not easy) and definitely has not been done. That study needs to (A) collect blood from a large # of
      healthy controls and patients from the same area using the same techniques (B) the investigators must be blinded
      (a horrible fate but if it’s necessary, it’s necessary :) the Alter/Lo study researchers were not and the WPI study did not
      report it was in the Science paper) (C) negative controls on XMRV should be checked for contamination prior to amplifying
      the samples (D)detailing the limits of detection is important E) replicating one element of the positive study using blood
      from positive patients collected by a phlebotomy lab.

      Note that Dr. Singh does not believe that it’s necessary to replicate every procedure
      from the first paper – one is enough.
      We can guess that Dr. Singh’s XMRV study probably (:)) closely replicates her advice and we can get prepared for
      a very precise methodological section – probably the most comprehensive yet as she details exactly what she did
      and didn’t do – which is what the National Cancer Institute, in fact, is asking XMRV researchers to do right now.
      Dr. Singhs autopsy study should be at the publishers now and her XMRV study is
      believed to be finished as well. Hopefully we will hear from her in another
      scientific journal soon.

    • Sample preparation? - the emphasis now is on ‘sample preparation’ with Dr. Mikovits
      reportedly stating that may be the major issue. Consider this, though; Dr. Peterson was
      able to dig up an XMRV positive sample in a sample that had been stored in his freezer for decades. The ‘Peterson’
      samples collected over the years in his practice were considered too suspect to use in the WPI’s Biobank – which
      started anew with new samples. Dr. Lo was able to find XMRV in samples that had been frozen for over a decade. Plus,
      the WPI was able to find XMRV in samples from some sort of blood bank, whose sample collection
      procedures are apparently
      unknown – at least in the detail at which the Blood Working Group is looking at. The upshot is that XMRV
      has been found several times in samples which appear to have been collected differently and certainly
      not with the kind of care that the BWG is looking at. Can sample collection really be the whole answer?

    • That Other Disorder - we’re so understandably focused on CFS that we tend to forget
      the other XMRV controversy – prostate cancer. XMRV seems to have a firmer hold on prostate cancer
      than ME/CFS at this point. Although the WPI/NCI/Cleveland clinic easily provided the strongest evidence
      for XMRV in any disease -
      the research community has been focused on PCR and PCR results by independent labs have been less forthcoming
      in CFS than prostate cancer. Yet, there’s still no consensus in prostate cancer either. 

      Take the last four studies; researchers
      from the National Cancer Institute looked at 800 (yes, 800) prostate tissue samples using very sensitive
      PCR and immunohistochemistry (which Dr.Singh believes may be the most sensitive test of all) and found zero, nothing – not
      a single sample was positive – which is what we see in CFS; XMRV is either VERY there or VERY not there.

      A Baylor School of Medicine study, on the other hand, found that XMRV was present in 22% of its
      144 samples (but questioned its role in prostate cancer). A Netherlands study, broke the ‘all or nothing’ mold by finding XMRV in prostate cancer
      but infrequently (4%) of prostate samples. They noted that “that XMRV could not be detected in consecutive tissue sections
      of the initial XMRV-positive cases.”; ie, they could find it in one tissue sample from a patient but not in the
      next one. They stated XMRV was ‘rarely detected’ and in ‘very low levels’ – and questioned whether it could
      play a role in prostate cancer. An earlier Mexican study found XMRV more health
      controls than people with prostate cancer (!) (1/55 vs 6/75). Finally, in maybe
      the strongest study, a Baylor group used PCR, antibodies
      and in situ fluorescence
      to find XMRV in 27% of people with prostate
      cancer. The results of all three methods were in accordance with each other – a
      strong finding.

      Conclusions – XMRV has never been detected in as a high percentage of
      prostate cancer patients (<30%) as in CFS but researchers are finding (or not
      finding it) in quite varying amounts (0-27%) and the role it plays in that
      disorder is unclear as well. As in ME/CFS most studies have concentrated on
      using PCR. The correct methodology for finding XMRV in prostate cancer is still
      being investigated. Oddly enough, given the focus on CFS, and most importantly
      the blood, we will know far sooner the best way to find XMRV in the blood than
      in prostate cancer.

    • Researcher Unlocks Key Factor in XMRV
      - Prohealth reported a Univ. of Missouri researcher has unlocked a
      key factor in XMRV in replication – something that could pay big dividends as
      researchers try to develop treatments for it. Dr. Stefan Sarafianos announced
      his lab had unlocked the crystal structure of a protein involved in viral
      replication potentially allowing researchers to create a molecule that locks
      onto the protein stopping the virus from replicating.
      If XMRV is validated in ME/CFS this would appear to clear a path for the development
      of designer drugs for the virus. Once again, the mind spins at how fast the research world can work when it wants to.

    • Amy Dockser Marcus Blogs Again
      - with a big yellow ‘X’ adorning her article, our most watchful big media
      rep, Amy Dockser Marcus at the Wall Street Journal, blogged about the CFSAC
      meeting mentioning the spark XMRV has given both the patient and research
      communities, the patient action (yeah!), Dr. Klimas’s call for a national
      network of treatment and research centers.
    • Dr. LeGrice and Dr. Houghton – both went down the contamination road a ways in
      their talks at the CFSAC. (Note, neither did completely. The NCI and Blood
      Working Group are looking at other options such as sample preparation
      and small differences in protocols.) While the general thrust of their talks was
      not anything anyone wanted to hear it bears noting that they are two more
      individuals whom XMRV appears to have thrust into the CFS universe….who have
      reservations about it now – and yet here they remain... 

      Dr.
      Houghton, Lasker Award winner, is a CFSAC member and Dr.
      LeGrice is now part of the Trans-NIH Working Group (which controls the cash flow for
      ME/CFS at the NIH). (He’s one of Dr. Mangan’s big wins as he tries to expand the
      reach and the power of the Group). Given their concerns it’s clear that
      something other than XMRV has obviously captured their
      attention. A talk with Dr. Houghton made it clear that he’s fascinated by the
      immunology and by Dr. Lerner’s EBV work and he told me he would work towards
      getting more clinical trials for EBV.
      These are two people whom XMRV has
      swept up into ME/CFS’s small orbit and no matter what happens to XMRV – it looks
      like they’re staying. We can also throw Ian Lipkin and the other CAA
      nominated researchers to the CFSAC committee. These are four year commitments!
      Prior to XMRV we couldn’t imagine people like that on the panel. Dr. Vernon told
      me she believes XMRV has produced a shift in the research communities awareness
      of and interest in ME/CFS.

    • Esme Reports: Norway XMRV Study in the ‘Zone’ on XMRV - Much of the research world the WPI wants to
      convince won’t be convinced by this because the tests were done at VIPDx but,
      look at the consistency of the positive results from Lillestrom Health Clinic in
      Norwary; 64% positive  -almost right on the WPI’s original figure, and then when you add in the serology results 70-something percent – excellent consistency that is either tracking
      XMRV infection in ME/CFS perfectly really or is tracking a contaminant that is devilishly consistent. 

      Remember Coffins statement about being able to drop mouse DNA in a swimming pool
      and being able to find it? If there’s a contaminant one wonders why they don’t
      find it in all samples? (It would interesting to compare the protocols of VIP Dx
      and Dr. Alter – do they use anything in common? a primer? a reagant? nothing? -
      hopefully they are both providing them to the NCI)The most likely outcome of the
      consistency of the positive results would seem to be that they are tracking a
      virus. This study is helpful but what the WPI really needs is for an independent clinic using an
      independent lab to validate its results – not VIP Dx.

      Dr. Mette Johnsgaard of The Lillestrom Health Clinic tested 24 patients and 3 healthy controls for XMRV using the culture test and found that 14 were positive. Of the negative tests, 11 were then retested with serology tests and 5 more positive results were found, bringing the total to 19 of 27. One of the positive serology samples was from a healthy control.The Lillestrom Health Clinic has now tested 80 patients and 50 are positive by either culture or serology test � a total of 62%. This is very close to the 67% of positive patient results reported by Mikovits, Lombardi, et al., in Science in Oct. 2009.
      The tests were done in cooperation with VIPdx labs in the USA.

      Dr. Mikovits to Talk Nov 28th - More information about these results will be given on the 28th of November in Oslo at the XMRV/MLV seminar with Dr. Judy Mikovits. Details of the seminar can been seen here:
      http://esme-eu.com/xmrv-mlv-seminar-oslo/category203.html Register by writing to: post@esme-eu.com

      The Lillestrom Health Clinic is currently cooperating with many international ME experts in order to share knowledge about testing, treatment and research. Dr. Johnsgaard is also cooperating with international experts who specialize in infectious diseases (Borna virus), retrovirology and biotoxic illnesses (Shoemaker), a probable secondary phenomenon in ME.

      Larger Study Planned – In November 2010, the clinic will launch a large international research project on Human Gammaretrovirus and ME.
      In Aug. 2010, Dr. Johnsgaard was interviewed by NRK (Norwegian National Broadcasting) where she confirmed the two first positive XMRV patients in Norway. With that interview Dr. Johnsgaard opened the public debate about ME and XMRV in the Norwegian medical and political environment. The same day, Norwegian politicians and doctors reacted positively in a follow-up interview on NRK (see links below)

    • Mindy Kitei’s Blistering Blog
      - Mindy Kitei exposed the distance between the
      say, your typical HIV researcher who expects nice tidy measurements of viral load – for HIV AND
      everything else and CFS patients who are almost being punished for
      not having what they could not have at this stage of the game. Its so reminiscent of the
      the early days of AIDS when protocol trumped patient suffering and even death. ME/CFS is not
      AIDS – people are not dying like flies – but many people are suffering unbelievably and they are disabled and
      some people do, and probably are, right now dying. 

      There are lots of issues in ME/CFS but the basic one is funding and without more
      funding we will never know the truth about this disorder, and more importantly
      neither will the research community. Are a substantial number of people coming
      down with heart disease or dying early? That is something that WOULD touch the
      scientific community but it won’t until the
      issue is
      studied rigorously and it hasn’t been. All we have, so far as I know, are two
      small and weak studies that contradict each other – and that is exactly the
      problem. Researchers don’t care about anecdotal data – it means NOTHING to them
      that Joe X or Mary Y died of ME/CFS. Not because they are bad people but because
      if they are going to keep being researchers they can only accept data from rigorous, well designed studies and when a
      multi-dimensional disease is only getting 4 million or so dollars a year in
      funding – you’re NOT going to get those studies.  If we want the Canadian
      Criteria to be accepted we need studies showing
      that that is a better definition…but you can’t get studies like  that if
      you’re getting peanuts every year.

      Mindy points the finger at
      the CFSAC but there’s also us – a community of 200,000 people (reportedly!) in
      the US that didn’t fill
      up the speaking slots, (telephone or otherwise) at last weeks CFSAC meeting and
      that left a small conference room that is within traveling distance
      of millions of people half or more empty. How many hundred or 1,000 people with ME/CFS live in Washington
      alone? (Somehow sick Mary Schweitzer, again, dragged herself all the way from Reno, Nevada.
      Mary, whether she is wheelchair bound or not is always there :) ) Last year CFSAC nominations came from
      groups all over the US; this year the only one I heard of was from the CFIDS Association.
      As a community our efforts are still disorganized and feeble. Hopefully the Time
      for Action campaign will provide a opening many people will step into. We do
      have the power – if we realize it – to make a huge difference. Mindy’s blog is about THEM but it’s
      also about US – the
      need for us to stop waiting for someone else to do it (aka the CFSAC) and embrace the opportunity, as many did, before us in the Time for
      Action campaign and to continue acting.

    • XMRV at the Tipping Point: A Tale of Two Conferences

    - check out my take
    on the last couple of weeks findings.

    • Sue at LiveWithCFS Blog – updates her NJ Conference Summary
      - 80% of Dr. Cheney’s patients were postive for XMRV. Why is that such good news? Because it
      we expect that the percent of XMRV positives will go up the more CFS is rigorously defined. His study won’t have much sway since it used VIP Dx but since contaminants
      don’t care how rigorously anyone is
      defined this is another nice check on the contamination talk. Fifty percent of the family members of people with XMRV
      were also positive (ouch!!!). The UK study provided another nice check; 50% of patients were positive by PCR and that figure
      went up to 80% using more methods and there was that low postive rate in the healthy controls again. 

      Dr. Mikovits she has a drawer full of studies no one will publish. This is undoubtedly the way it will be
      until XMRV’s fate is clarified – at which point, the WPI, hopefully is redeemed (in a very big way) and
      publications start clamoring for publications from the little Institute that indeed rocked the world.
      (But why not the UK study???)

      Sue reported “Dr. Mikovitz also said that some of the people who’ve been
      suggesting contamination are people who were involved with the original studies and who saw all of
      the original data, including those which proved contamination was impossible”
      – the inference being that
      some people just don’t want this finding to come out. I would guess, however, that it just reflects the
      uncertainty in the scientific community (and the Weiss paper that just came out); on the one hand you have
      “the best first study’ you could think of, followed by a raft of mostly
      negative studies. My guess is that the
      scientific community is more than a little puzzled how to put these two results together. The fact that the Blood Working
      Group and the NCI are looking at every detail, from blood storage to small methodological details that usually
      aren’t even printed suggests they are more confused than anything.

      Slipping Into Conspiracy Theory Mode - there was also this “The prevailing
      theory seems to be this: if the CDC confirms that XMRV, a new, dangerous,
      and transmissible retrovirus, is present in people with CFS (and the CDC
      has estimated the number of adults in the US with CFS to be 4 million),
      then they have a huge public health crisis on their hands.”

      Boy do I not
      buy this. For one, this is way bigger than the CDC – we have multiple federal and other
      groups working on XMRV. For two, I don’t think the government is in the business of
      covering up pathogens – call me naive, I just don’t – particularly when well known researchers
      from several different branches of the govt are involved. Coverups don’t
      work very well once they spread beyond a small group of people. Nor would the
      NIH
      hire an ace pathogen detective to lead the search if it was interested in
      covering up anything. For three – any attempt to coverup this pathogen is doomed
      to fail because other, good researchers are involved – the truth is going to
      come out. XMRV just happens to be a tough nut to crack

    • Cracking That Nut - Dr. LeGrice, if I didn’t report it before, told me he
      thought the contamination (and I suppose, blood storage issues) will be resolved
      within 3 weeks. The prognosticators have all been wrong thus far on time- so
      let’s give him a bit more time; say a month from now – according to Dr. LeGrice,
      we should know.

    • Dr. Mikovits Talks -
    • the Patient Advocate has been busy. He was at the
      Research section of the CFSAC meeting, then it was over to New Jersey for the
      New Jersey conference. If you’ve seen Dr.
      Mikovits talk you know that when she talks she can really talk – she’s almost
      like a force of nature when she gets going…and she really talked at this
      conference.

      You’ll have to read Chris’s blog
      to get the complete picture but some key points stuck out.

      Dr. Sandra Ruscetti, a co-author of the original Science paper, has
      generally been in the background but she is a key, key figure because of her long experience with the murine
      leukemia viruses (MLV’s)- of which XMRV is one. The point is that she’s tangled with these
      viruses (and the contamination problems they pose) for a long time and Dr. Mikovits
      reportedly referred several times to the key role
      she played in isolating the virus.

      Sequence Diversity is Our Friend” – Dr LeGrice referred to the
      genetic homogeneity of the virus in the Science paper – a red flag because contaminants don’t mutate but viruses do
      but this has always been a weak point because it was founded, as I remember, on
      the sequencing of only two and half strains. Dr. Mikovits pointed out that as XMRV is studied more
      the WPI is finding more and more sequence variation – a very good sign.

      Reservoirs - XMRV is found in very low amounts in the cells studied thus far – perhaps too low to cause
      alot of damage (although there is some disagreement here)- so it would behoove researchers to find a tissue it is
      replicating in. Apparently Dr. Mikovits has some ideas (or results) about that but what exactly they
      we didn’t get. She at least has enough information to speculate on them.

      Sample processing is everything” – The Blood Working Group is going
      back  to the drawing board and looking at very basic aspects of sample processing in their
      search to explain the disparate results. At the XMRV Workshop Dr. Mikovits
      intimated there was some big news here. Dr. LeGrice wasn’t willing to go so far
      in his talk but now our PA reports that Dr. Mikovits stated ‘sample processing is everything’. Hopefully so;
      several candidates to explain the results have popped up over time; there was culturing
      (or the lack of it),and there was APOBEC3 editing and/or the use of the prostate clone. Perhaps they all play a role in the
      funky results gotten thus far.


      The X Variant and P-Variants are not Variants at all But Separate Species
      -Alter/Lo
      are reportedly fleshing out the full genetic sequences of their ‘pMLV she’s” but the WPI has
      their samples as well (hundreds of them reportedly) and they have apparently fleshed out
      their sequences as well found that CFS patients contain a bevy of closely related
      but different viruses – not variants – which is what both LeGrice and Coffin
      suggested.

      The evidence for several different types of MLV’s
      in CFS is – the pMLV’s from Alter and Hansen study, XMRV from the WPI study and, now confirmation of the pMLV’s from the WPI. Presumably the
      WPI found the pMLV’s in the original study but because they only sequenced 2 1/2 viruses – which looked like XMRV – the pMLV’s
      did not make it into the original paper. Now that they’ve sequenced more of the several hundred isolates they have – the pMLV’s are showing
      up; they were there from the beginning but were hidden from view.

      But why did Alter/Lo only pick up the pMLV’s in their samples?
      We don’t know but Dr. Mikovits reported that when Dr. Ruscetti cultured Alter’s samples he found XMRV as well – which, of course, is
      great news The WPI/NCI findings, if they hold up, will destroy the attempt to present the Alter/Hansen studies as ‘unrelated’ to the WPI’s XMRV finding.

      XMRV and its variants are not mouse virus’s - It will be interesting learning what this means; if not a mouse then what,
      a uniquely human virus?

      There’s much more than that. It was clearly a whirlwind presentation and one wonders if only Dr. Mikovits could
      have gotten so much information in in under an hour.

      The dichotomy between the two XMRV ‘camps’
      at the moment is astonishing. Just a few days after
      Dr. LeGrice warned about the ‘very real’ possibility of contamination Dr. Mikovits blew the wheels off the
      XMRV story with her report of how the WPI and Dr. Ruscetti continue to deepen their understanding of this virus. Dr. Mikovits was
      clearly very confident at the New Jersey Conference, and that in itself is good
      news for XMRV.

    • Cooperative Diagnostics Study Gets Expected Results -
      The Cooperative Diagnostics Lab jumped on XMRV early and their long-rumored study
      has finally surfaced but it was on autism not CFS. (Reports are that no XMRV was found in their CFS patients). Using CDC assays and the
      prostate cancer XMRV clone they reported zero XMRV from PCR and antibody tests to autistic children born to parents with CFS, other autistic children and people with fibromyalgia. While this
      study did nothing to strengthen the XMRV/CFS connection the ability of CD to come up with that many CFS parents with autistic children was an
      eye-opener for me.

    • So How Much Does it Cost to REALLY Study XMRV? - well, it costs alot of money.
      At the IACFS/ME Conference we found out that Ian Lipkin’s multicenter XMRV
      study for CFS is going to set the NIH back a whopping 1.3 million dollars. We haven’t seen a million dollar study
      for CFS since the Centers For Disease Control started their Patient Registry project….(ba
      da bum….). So far the NIH has awarded
      three grants to study CFS and XMRV for a grand total of about $2,000,000; the Lipkin is easily the largest and the others include Dr.
      Hansen’s $270,000 look at Dr. Bell’s patients and Dr. Singh’s $312,000 look at Dr. Bateman’s patients.
      One wonders what the total cost of the effort at this point are. The great thing
      about these studies is that the wealth of data these experienced doctor’s can provide. Thus far Dr. Peterson, Dr. Levine,
      Dr. Cheney, Dr. Klimas, Dr. Lapp and Dr. Bateman in the US (and I’m sure I’ve missed some)
      have contributed CFS patients for XMRV studies.

    • XMRV Redux at the CFSAC Meeting - Still smarting from not asking Dr. LeGrice the
      obvious antibody
      question I asked Dr. Houghton. Dr. Houghton, I found out, is, believe it or not a Lasker award winner
      for discovering hepatitis C, but he is not a retrovirologist and retroviruses are very different from viruses.
      When I popped the antibody question he said well, the antibodies could be cross-reacting with another virus
      which in itself would be interesting – what virus could that be? Another MLV?

      I said but consider what would have to
      happen for both the PCR AND the antibody test to be wrong. First you have a strange and difficult to pin
      down case of contamination. Then ME/CFS patients (but not the healthy controls) will
      have to just happen to be harboring another virus that the antibody
      test just happens to pick up. (???) The statistical probability that both things
      went wrong (in just the right way) have to be extremely low.  Dr. Houghton agreed that that was an issue. He
      also made clear that he
      thought the Science paper was an extroardinarily well done paper.

      Dr. Houghton also wanted to be clear that a) he was providing his personal opinion, b) he is not a
      retrovirologist and c) it was the Weiss paper that really turned him around. By the
      way, he was very impressed by the
      EBV findings presented at the meeting; he said CFS looks like a viral disease to him
      and he’s going to work hard to try and get something done with EBV.

      That “Zone of Chaos” - How much are researchers befuddled? The NCI is developing a website where
      they are asking researchers to make the tiniest details of their protocols public so that they can examine and see
      if something very small -
      and, heretofore unthought of – might be causing the disparate results. The fact they are interested in doing this
      can only be a reflection of the strength of WPI’s original work. There’s the PCR
      work, the antibody work, growing the virus, showing that cell free media from
      the patients blood could infect other cells….these are all interlocking pieces of the
      puzzle – each of which strengthens the other; its difficult to break that
      chain…….there is clearly no easy answer to the differing results.

      The CFIDS Association – Glaxo-Smith Kline XMRV study - I asked Kim McCleary how the
      GSK XMRV study was going and when the results
      would be back. She said it was in the hands of GSK. Was culturing being done? Yes, she said the investigators had been in
      touch with the Dr. Mikovits in order to get her exact protocols and that they were doing
      extensive testing. The
      study is double-blinded – so they won’t know anything until they break the codes and
      then all will be revealed but she didn’t know when.  I asked if the study
      would be published and she said publishing is a requirement for using BioBank samples.

      The Klimas Study – Dr. Klimas has had her CFS samples at four labs, if I remember correctly, since February. One of
      them is in a Yale lab lead by a co-worker of Dr. Singhs. No funding has been provided so they
      are doing the analyses slowly. The announcement that an edition of Retrovirology early next year (I think) will be
      devoted to XMRV, will hopefully, Dr. Klimas said, speed up the process. This should be a particularly valuable study because of
      all the other data (including alot of immune data) Dr. Klimas has collected on these patients.

      That Negative Chinese study - with regard to the Chinese study Kim McCleary said – people in the US have
      enough trouble defining and diagnosing CFS here – which makes it very difficult to assess anything that
      comes out of China, which does not have a background in CFS research.

    • XMRV’s Tough Week - at the CFSAC Meeting Dr. Stuart LeGrice presented an overview of the
      Workshop but the gist of his presentation was clear; he believes there is a good chance
      the positive XMRV results are due to contamination. Citing how incredibly PCR’s have become at
      picking up the smallest amounts of DNA (eg Dr. Coffin’s analogy swimming pool analogy) and
      how ubiquitous mouse DNA is in medical research environments he laid out a case for some sort of
      unforseen contamination. The disparate results have clearly got the researchers at the Blood Working Group
      flummoxed and they are looking, he said, at aspects of PCR and sample testing they’ve never looked at in
      detail before. 

      Dr. LeGrice’s guess, at this point, would tend towards contamination at some part of the
      ‘food chain’ but he is not tied that and cited other possibilities the Blood
      Working Group is examining including how long the blood is stored, what test
      tubes it is stored in, how long before it sits out before it is frozen -
      basically they’re looking at every stage of the process. At the XMRV Int.
      Workshop Dr. Mikovits intimated they had found a key factor in sample
      preparation that could explain the disparate results; if Dr. LeGrice knew
      about that he wasn’t saying but it obviously remains a real possibility. The only good news from Dr. LeGrice
      on the contamination front was that if mouse DNA is involved they should know and soon – within 3 weeks, he said,
      he thought the contamination question will be laid to rest one way or the other.

      Dr. Houghton - He was followed by Dr. Houghton, a hepatitis C researcher, and CFSAC panel member who also leaned
      heavily on the possibility of the cotamination stating that the events of the last couple of weeks had
      dampened his enthusiasm for XMRV. He cited how easily it was to reproduce the result of the hepatitis
      c when it was first found. On the other side, though, we have Dr. Singh who’s
      worked with  mouse retroviruses for 10 years and
      with XMRV itself for four who told me she was not surprised at the trouble researchers were having
      clarifying XMRV and who felt contamination was not a possibility. We also have Sandra Ruscetti, an important
      figure in murine retrovirus research for decades who also presumably knows how to handle murine retroviruses – so we shall
      see.

      Unfortunately my mind went blank after LeGrice’s presentation and I forgot to ask the key antibody
      question – how can you have antibodies to a contaminant?  He obviously would
      have an answer to such a simple question but it would have been good to hear it. I will try to corner Dr. Houghton today. More on
      news on XMRV from the CFSAC meeting (it’s not all bad) when a summary comes out.


      Three More (Negative) Studies
      – Meanwhile three more negative studies came out; a UK/Swiss study involving Dr. McClure
      found no XMRV in several hundred patients with HIV or hepatitis C, the Mass Felsenstein study looking
      for it in
      CFS, HIV, rheumatoid arthritis and organ transplant patents and a Chinese study looking
      in CFS patients. The Felsenstein
      study was painful given the high hopes for it.

    • Now They’ve Done It! - the long rumored ban on blood donations in the UK was finally announced not because the
      patients are viral but because they are ill and like other patients with -remitting-relapsing conditions like MS, it just doesn’t
      pay to risk a relapse. It must have sounded odd to UK ME/CFS ears to have the goverment lump them in with multiple sclerosis
      - a ‘real’ disorder deserving of real research in the UK’s books but there it was. This time the BBC actually tried to cover
      both sides of story, citing the retrovirus connection some (deluded :) ) patient groups think might also play a
      role in the govts decision.
    • Who is Stuart  LeGrice and Why is he Speaking at the CFSAC Meeting? – Dr. LeGrice will author the XMRV presentation at the CFSAC tommorrow.
      We haven’t heard alot about him. His name did poke up early in the discussion when he noted how many drugs might
      available for XMRV. The director of the National Cancer Institute’s Center of Excellence in HIV/AIDS and Cancer Virology, he
      has, as one suspect, quite a resume having co-authored over 155 papers, many of them on HIV/AIDS. He’s another example of the kind of top-flight researcher XMRV has attracted. Other than professional interest his direct
      connection to the virus is unclear.
    • Dr. Mikovits is on the Move – Dr. Mikovits just spoke at UCLA and will be darting up to Oslo, Norway on
      Nov 28th to give a talk on “XMRV and other MLV’s in Chronic Fatigue Syndrome”, the title suggesting, of course, that the
      pMLV sequences found in ME/CFS actually belong to different MLV’s and not to variants of XMRV.
      (Thanks to Anne for the tip).

    • Lewellyn King Talks
      - White House Chronicler Lewellyn King sides with CFS. You don’t
      hear this kind of perceptive talk much. Check this out “Yet there is a vast archipelago of diseases as cruel in their impact, horrible to bear and crying out for research that is not sporadic, underfunded or, through ignorance, misdirected.” 

      The man is speaking the truth to power. And then there’s this

      One such is Chronic Fatigue Syndrome (CFS), a name so gentle that it belies
      the ghastliness of this affliction. Sufferers accuse the U.S. government,
      abetted by other governments, of choosing this name over
      the older and more commanding name, myalgic encephalomyelitis.

      Plus there was a roundtable Mr King led which
      on PBS that blogger Heida Bauer thought went quite well. Check out her blog for news of the PBS version of CFS and XMRV.
      Keep talking Mr. King.

    • ACT UP for CFS and XMRV! -
      Peggy Munson argues it’s time to ACT UP for CFS in her latest
      blog: the Best Offense is a Good Offense – there’s no denying Peggy is onto something
      powerful when she suggests that above all it would help if people with ME/CFS made
      some more noise. My brother is a lobbyist and he told me that the squeaky wheel does definitely get the most
      grease. It’s not as easy for CFS as it was for AIDS in the 1980′s. Gay people often
      lived in close contact -making it easier for them to organize when HIV/AIDS hit
      while many people with ME/CFS rarely have occasion to physically meet someone
      with their disease but we do have the internet now.   I don’t agree that attempts to use the
      ‘inside voice’ have reinforced the power of those keeping us down – I think all attempts
      to advocate do
      just the opposite but there is no doubt that we have barely scratched the surface of advocacy – something
      Peggy’s blog vividly demonstrates
      .

    • What is Next For XMRV?
      - Check out some of the studies we may be looking
      forward to seeing over the next couple of months.
    • heck out the Newly Updated (and Color-Coded) XMRV
      Studies Page
    • MLV’s, AIDS, ME/CFS and Alcohol Intolerance
      - Nasta778 on the PR Forums posted a very interesting abstract. What do researchers do to induce an AIDs’like
      condition in mice? They don’t give them HIV….they infect them with MLV’s (!) because MLV’s play havoc with their
      immune systems causing them to have an ‘immune deficiency syndrome’
      infections.
      The paper reported:
      The similarities between murine AIDS and human AIDS are striking, with similar changes in immune functions, T-cell differentiation,
      cytokine production, disease resistance and oxidative stress
      �”
      Of course mice are not humans but it is an interesting correlation…MLV’s =
      AIDS in mice, ME/CFS in humans???? 

      When they fed the MLV infected mice alcohol a strange pattern of protein expression
      involving one mitochondrial protein emerged which appeared to exacerbate the effects of the original infection. The abstract ends “These results suggest that chronic alcohol consumption may exacerbate the effects of viral infection on the heart
      by lowering the stress response leading to de-protection and further cytotoxic effects.”
      One wonders what effects alcohol consumption
      in alcohol intolerant people such as people with ME/CFS has? Does this finding say
      something about the problems with alcohol intolerance in ME/CFS? Could small
      amounts of alcohol be disrupting the stress response, mess with the mitochondria and
      result in increased oxidative stress? The alcohol conundrum in ME/CFS to my
      knowledge has never been addressed anywhere….

      How common is alcohol intolerance in ME/CFS? Let’s find out – take the
      Alcohol Tolerance Poll!

      Kate Bishop
      Stays in the Hunt
      - Kate Bishop, a UK researcher, was part of the Groom-Kerr team which did
      not find XMRV but she also discovered the APOBEC3 editing that was a revelation to Dr. Mikovits and which Dr. Mikovits believes
      could explain some of the negative study results.

      Voner in the PR
      Forums reported that she is starting up a big project to look at various factors including XMRV prevalence
      on the general population and ‘in patient groups of particular interest’ – which, one would assume, does not include ME/CFS – unless
      she has developed new techniques. She does report that besides the PCR and serology tests her lab has developed she is
      developing ELISA tests for large scale screening and culture tests…note that she is developing CULTURE TESTS….(how
      could she not run a few of her blood samples through them????)

      She’s also looking at how XMRV infects different
      cells under a variety of condition, at hormonal and IFN-10′s effects on it’s activity and more. There’s alot going on in this study – it’s a big effort and indicates that,
      at least with this UK researcher, interest in XMRV is alive and well.

      Big Pharma Waits….On XMRV – a question to Dr. Light at the CFIDS Association Research webinar about the diagnositic capability of his exciting work on increased muscle and other receptor increases in ME/CFS shed some light on how Big Pharma works. Dr. Light’s work suggests people with ME/CFS have a distinct receptor signature – basically a biomarker, and therefore possibly a diagnostic tool (finally) for ME/CFS. It’s definitely exciting stuff. He reported that Pharamceutical companies were interested in developing it until XMRV showed up with it’s promise of a cheaper, easier biomarker. One thing at a time for Pharma…

      - the only question is what took it so long? If
      XMRV is in the blood supply and the blood supply has not been screened for it
      then hemophiliacs would. just as they did with HIV/AIDS, presumably take a big
      hit. No one has shown that yet but if I had to get transfusions with some
      regularity news that a new RETROVIRUS, of all things, might be in the blood,
      suppose would catch get my attention.

      Results
      - the XMRV positive survey has found that of the 55 respondents 60%
      had acute onset and 37%, interestingly enough, had gradual onset (interesting!)
      A full third had mononucleosis and believed it contributed to the onset of their
      disease. The most common age of onset was easily from 30-39. With some nice
      colorful graphs – nice job! Functionality would be interesting to determine – is
      there a range of illness severity or were the XMRV positive patients really ill?

    • Brits and Yanks Square Off over XMRV
      - Dr. Erlwein, Dr. McClure and the rest of the Imperial College
      retrovirology team (plus Dr. John Martin after all these years!) attempted to pin the Alter/Lo tean in the US down with some tough questions in
      PNAS’s Journal Letter section. Alter/Lo had to respond and they did. Were they nailed to the wall? Or did they
      knock the Brits questions out of the park? Check it out in
      Batter Up! The XMLV/MLV debate
      Continues.
    • A Rumor of Viruses
      - Thirteen years ago John Weiss was burned by a viral discovery that, years
      later, turned out not to be one. The author of ‘Rumor Viruses’ he’s made it his
      job to warn the research world of the perils of viral discovery. Now in this
      PubMedCentral article he’s turned his attention to XMRV. 

      He makes the point that XMLV’s (Xenotropic murine leukemia viruses)- which are
      distinct from, but closely related to XMRV’s – are commonly found in labs that
      have done cancer research and may be widespread in laboratory reagents. He notes
      that the Hot Taq polymerase enzyme has mouse antibodies and can carry XMLV’s
      (Check out the above article for Alter/Lo’s response to the Taq question).
      Except for one other type of virus murine leukemia viruses are the most
      problematic because of their prevalence in the medical research worldp ie it’s
      easy to contaminate a sample with them.

      The most intriguing part of Weiss’s essay concerns his own
      viral discovery that turned out not to be one. In that instance, as well, the putative virus was found in more
      sick patients than healthy controls – seemingly a clear sign that contamination
      had not occurred.  As to how or why the
      contamination did
      occur, Weiss was never able to tell – the only idea he could come up with was that the ill patient samples
      had been handled more than the healthy control samples and that somehow allowed the contaminant entry.
      His story pointed out the cautionary tale that even labs that seem to do
      everything right can fail.

      He
      notes that “If the healthy samples had come from strictly derived case-control collections in which the control vials
      were handled in exactly the same manner, for the same time and with the same frequency as the vials containing the clinical specimens (which has not been done for CFS), we
      might not have observed the bias towards detection in cases above controls.

      Reading Dr. Weisses recipe for success, however, does make one glad for the
      Singh study (and probably others) which are doing exactly as he recommends.

      Another point he brings up is the apparent ease with which both the WPI group
      and Alter/Lo group found the viruses. Both were able to pick it up using a
      single round of PCR while other groups were unable to find any trace of it (or
      them) after two rounds of PCR – a good point that Alter/Lo responded to but
      which has yet to receive a definitive answer.

      Dr. Weiss does bring up some good points but I found his paper to be
      surprisingly light; more an essay than a probing analysis of a problematic
      finding. There was no discussion of how effective the efforts of the WPI, NCI
      and now Alter/Lo labs to account for the presence of a possible contaminant
      were. There was no discussion about geographical differences in sequences or the
      possibilities of recombination or different primer sets. In the end Weiss took a
      rather anecdotal approach to warn the research world about a finding he thinks
      is spurious; a not very convincing combination at all and one which I guess will
      do little to advance his cause. Certainly the ‘opposition’ can be more rigorous
      in their appraisal of XMRV.

    • Patients on Retrovirals Talk…to Mindy Kitei - Blogger Mindy Kitei would like to talk to
      ME/CFS patients who have tried (or are trying) antiretrovirals on or off the record. Email: mindykitei.cfscentral@comcast.net
    • Ali Deckoff-Jones Goes Back to School – Dr. Deckoff-Jones daughter is back in school. She may not be kicking up her heels all the time
      but how much progress she’s made readily becomes evident in the story she tells of her
      last attempt at school; not a pretty one that was
      filled, as has so often happened, with arrogant school officials telling her to
      ‘just cowboyup girl!”. (That didn’t go over well. Doesn’t everyone have at least
      one memory like this? I still remember my consult with my University MD decades
      ago…)  She reports that CFS ‘stole her voice’ before and now she has it
      back- and she’s talking (and she’s a good writer, as well :) ).
    • Dr. Deckoff’s Blog “My Opinion” is Very Intriguing
      - Look at any organ system she said – you’ll find problems, but that does not mean that that particular organ
      system is ‘it’ in ME/CFS. Having been athletic for years
      after presenting with
      diastolic dysfunction (which has actually improved over time) she is no believer
      in the importance of diastolic heart failure, for instance. (Unfortunately no
      attempt has been made to fashion together a coherent theory regarding diastolic
      dysfunction and plop it into the
      medical journal dedicated to theory. A mother of a daughter with ME/CFS got her H2S theory published last
      year). She notes that the ‘heart failure’ possibly present in ME?CFS is definitively not the heart failure
      leads to complete heart failure and death, usuually within a few years (something Dr. Cheney
      goes to some pains now to point out.  He always did
      point it out – but the phrase ‘CFS Patients are in Heart Failure’ seemed to
      easily drown out that fact at the time.) 

      Dr. Deckoff would suggest that all these organ system abnormalities are probably
      due to viruses (something Dr. Cheney, in all fairness, appears to agree to).
      Then she goes onto explore the pluses and minuses of anti-retroviral therapy and
      of XMRV itself. The fact that some people with XMRV are completely healthy means
      it’s going to be XMRV plus that does the deal in ME/CFS patients; XMRV plus a a genetic abnormality or XMRV plus another virus or
      plus ???? The gist is that while we do have some data we are in the early phases
      of learning what works and what doesn’t. Nevertheless Dr. Deckoff is
      increasingly clear that retroviruses are ‘it’ or, at least a big part of ‘it’ -
      at least in her and her daughter’s case and who can blame her? Her daughter is
      back in school and she is beginning to think of
      returning to practice.

    • The Future of XMRV Testing: HIV and XMRV
      - a look at the ‘options’ available for HIV testing suggests what the future
      of XMRV testing will be like.
      Check out what happens in HIV. First PCR tests aren’t even a option for HIV
      because they are expensive, difficult to administer and more difficult to
      interpret relative to other testing options.
      http://www.avert.org/testing.htm Antibodies
      and immunoassays are the ticket in HIV these days. 

      Because there is a small
      chance of a false positive antibody test (even now) a positive HIV test needs to be
      followed up with another test and you generally have your choice of four; a
      Western Blot Assay – which is accurate unless you happen to have another viral
      infection going on (in which case it’s not), an immunofluorescence assay, a line
      immunoassay or if you can’t get those, a second ELISA test (using a different brand of test.) Having two
      positive tests means you are definitively positive for HIV.

      Not surprisingly given XMRV has just caught the research worlds attention
      recently, we are far from that level of sophistication. We have the PCR test
      and the antibody test but since a positive result from either means that you are
      ‘positive’ there is no ‘check test’ yet. At some point there will be
      one – probably some sort of immunassay combined with the standard antibody test.
      (Note that with HIV the number of false positives is, of course, very small
      (0.2%) – we’re not talking huge numbers of people that would become wrongly
      informed they have HIV if they just took one test.)

    • Of Mice and Men: The CFIDS Association Report on XMRV Workshop
      is out. The CAA issued a pretty comprehensive report on the
      XMRV Workshop complete with images.

    • Living with CFS Blogger Talks With Dr. McClure
      - ‘Living with CFS’ basically
      got Dr. McClure to get down to the nitty gritty about XMRV in a series of
      emails. Dr. McClure believes the WPI’s results and presumably Dr Alter’s results
      (and Dr. Hansen’s results? and the UK Mikovits study results?) are probably due
      to contamination and were confounded by the fact that blinding/randomization was
      not done and that not all the samples were treated ‘in the same way and at the
      same time’. Of course she has her points – she is a published retrovirologist -
      and we shall see. Dr. Singh is in the middle of her study which is designed to
      answer all of Dr. McClures concerns and, of course, the DHHS and NIH studies
      will as well. 

      Dr. McClure is making some big claims here – she’s out in front of
      most researchers in her certainty about the situation – and we’ll see if she’s
      right and if Dr. Mikovits, the Ruscetti’s, Dr. Silverman, Dr. Alter and Dr. Lo and Dr.
      Hansen (and even Dr. Singh – who said she saw no chance of contamination) are
      wrong.

      Most researchers are still sitting on the fence. My guess is
      that the situation will be over, one way or another, when Dr. Coffin starts
      leaning one way or another. For now he’s on the fence; Dr. McClure, on the other
      hand, has maybe one
      toe on the fence. We shall see if she ends up looking prescient or if she ends
      up looking like somebody who spoke too much too publically too soon.

    • Dr. Mikovits Lectures at Center for AIDS Research  at UCLA
      – We’ve
      heard just a bit about how ‘promiscuous’ the MLV viruses are; how they like to
      recombine with each other. At one point Dr. Mikovits suggested more than one
      virus or variant may be needed for them to survive in the body and Dr. S.
      Ruscetti is reportedly looking at this now. Dr. Mikovits will be digging into
      some cutting edge research on her talk “MLV related viruses in neuroimmune
      disease and cancer: Is XMRV or PMRV the pathogenic variant or does it take two
      to tango?
      � in her talk on Oct. 8th. Thanks to Berthe for digging this up.

    • Dr. De Meirleir Talks
      – Lot’s of stuff in Berthe’s report on Dr. De
      Meirleirs talk on XMRV. Dr. DeMeirleir was definitely ready to talk and he
      spilled the beans on the results of a number of ongoing studies. He said XMRV
      has been found in ten diseases (!) which could be good or bad news depending on
      which diseases it was found in. (NEID’s, cancer, autoimmune and neurological
      disorders – good; just about everything else bad.) The Alter/Lo study is being
      replicated in Europe; so far about 50% are testing positive for XMRV. Another
      study will show XMRV is transmitted sexually but he is not supposed to be
      talking about it (shhhhhhh……). He does not appear to be that excited about
      anti-retrovirals. The Blomberg study patients came from him.
    • MLV’s Showed up in ME/CFS in 1994? -
      Mindy Kitei found an intriguing reference to a report by Diack of murine
      leukemia retrovirus like particles isolated in a third of ME/CFS patients. The
      authors noted how preliminary the finding was and the ‘considerable work’ needed
      to clarify it – which apparently was never done.

    • XMRV Shows Up in Autistic Child and Mother
      - in a long and interesting blog
      Kent Heckenlively reports that his wife, his autistic daughter and his
      mother-in-law have tested positive for XMRV. His wife, interestingly enough, has
      been showing showing increasing cognitive problems and his mother-in-law has
      celiac sprue. He believes XMRV’s integration sites into cellular genomes fits
      well with the methylation and mitochondrial problems that may be occurring in
      autism. He also questions whether XMRV infection in the blood vessels of the
      brain could be affecting both CFS and autism patients. He notes that the
      treatments being discussed on the Phoenix Rising Forums mirror those being
      discussed on autism sites.
    • Dr. McClure Talks
      - At a panel for the American Society of Microbiology Dr. McClure stated she was
      starting to work on prostate cancer patients with XMRV when she was approached
      to test CFS patients even though she had no experience with CFS. Since her PCR
      was ready she agreed to do it.  She stated that the patients whose samples she
      tested had the been the focus of 150 papers (!???). She took a hard line against
      Alter/Lo’s contention that their paper confirmed or validated the WPI’s findings
      -stating that it didn’t -and then she noted that the pMLV’s found were more were
      more closely related to the dreaded endogenous retroviruses than to XMRV. She
      stated the genetic sequences she used in her PCR should have picked up the pMLV’s
      that the Alter group found. 

      She does not believe the disparity in results could be due to patient selection.
      She got a little snarky when she seemed to
      indirectly suggest Dr. Mikovits does not know basic virology when she said Dr. Mikovits wants us to isolate the virus but,
      of course, we can’t isolate the virus until we find it.

      She noted that
      her group was criticized for not using the same primers as the WPI and that they
      went back and subsequently used the same primers as the WPI and still didn’t
      find anything – which is something we have not heard. She also stated that that
      her positive control was Bob Silverman’s prostate cancer sample – which Dr.
      Mikovits believes is problematic. While at times saying the right things her
      overall stance to XMRV is emphatically that it’s not there; she continually
      emphasizes negative findings while giving little heed to questions that have
      been raised why those findings might
      be wrong. She is a long way from Dr. Singh’s cautionary warnings about the early
      stages of research or even Dr. Coffin’s ‘zone of chaos’; in her mind the issue
      appears to be settled.

      She did note that the interest in the virus was
      extroardinary and that the Director of NIH was present in several sessions of the Workshop. (Dr. Vernon said
      she was astonished to see him sit through 75% of the Workshop – something she had never seen before). Dr McClure stated that
      her opinion really didn’t matter (which is true, although she does keep repeating it
      :) ) and that it will
      ALL be sorted out in a few
      months time.

    • And Talks - Dr. McClure appears to be enjoying her time in the limelight;
      besides her initial study she has done two videotaped chats this week, she has
      penned several editorials and she has been interviewed several times; for
      someone with no connections to CFS she has become quite connected very quickly. Dr.
      Racaniello caught up with her at a huge meeting (10,000) and they had a rather
      long and quite involved talk. Whether she’s right or not she is clearly well
      versed in the field. 

      Although she stated she has doubts she is planning on
      replicating the culture techniques recommended by the WPI using samples provided
      by them. (This appeared to work for Dr. Hansen). She believes XMRV is real in
      prostate cancer and not in ME/CFS, at least at this point. Dr. Racaniello
      pointed out that only the Science paper by the WPI had a positive control to
      test off of – something she seemed to agree was important. (Dr. McClure lauded the CDC paper
      “it was the one we were all waiting for” thiswhile Dr. Racaniello largely
      dismissed it because it did not have a positive control). Interestingly, she has
      never met Dr. Wessely! (It was his samples she tested.)

      Dr McClure noted that
      MLV’s have never been found in humans before while Dr. Racaniello noted that if you drop human cells, if I got this right,
      into mice tissues they become infected with gammaretroviruses (the potential is
      clearly there). She felt it was rather strange for two separate viruses
      (XMRV/MLV’s) to show up in two groups of ME/CFS patients and clearly still
      believes contamination could be a factor. They both agreed
      that XMRV/MLV’s could be present in the human population but only show up in
      people who were ill. The interview takes place about 45 minutes into the tape.

    • XMRV International Workshop Abstracts Part II:  

      German Researcher Draws Blanks Again – Norbert Bannert is not having an
      easy time with XMRV. First he tried to find it in prostate cancer and failed and now he’s to find it
      in ME/CFS and failed. Unlike other researchers he activated the PBMC’s he sampled and then cultured them
      in order to boost the viral presence but he used a different process than the WPI and Dr. Hansen did.
      Then he tried to transfer the virus to the LnCap cells the WPI does use in at least some samples but to no avail.He did show, though,
      that XMRV is infectious; that is he was able to produce the virus from a cell line and showed that it
      could infect cells. His particular population – a small group of 39 CFS patients -
      was negative, as were his healthy controls and a group of MS patients. if

      Swedish Study Comes Up Empty - Dr. Blomberg and his ‘Swedish XMRV Study Group’ – used quantitative PCR – the same type of
      PCR Dr. Singh favors, to look for XMRV. Dr. Blomberg used the same LnCap cells the WPI recommends to culture the virus for five days
      for the same period of time
      the WPI recommends. Blomberg found
      no XMRV in 50 people with ME/CFS, 400 prostate cancer samples or 200 controls using what he called his ‘novel’ PCR methods.
      He did get a few weakly positive (or ‘uncertain’) samples from ME/CFS patients. We can see from both these studies and the Mikovits and
      Hansen studies that as time goes on studies are getting more complex and are starting to hue more towards using the
      WPI’s techniques. Dr. Singh is currently engaged in an XMRV study in Salt Lake City which is using LnCap cells as well.

      XMRV Blood Working Group is Halfway There – Key Problem Identified? - Phase II of the project, which compared different labs ability to
      find XMRV in WPI identified positive patients is complete! One thing they looked was whether the 2-4 day delay in
      processing that is common in many labs affects a labs ability to find the virus. Dr. Mikovits’
      stated that blood preparation techniques are important and it brings to mind Dr. Singh’s
      painstaking attention to this factor in her study. (What an astonishing finding
      that would be if it was something as simple as blood storage all along….) In Phase III they will determine the best assay using blinded tests
      and in phase IV they will look at 300 samples from the Western United States. They will be done by the end of the year.

      Finding XMRV’s Tissue Reservoir – Dr. Ruscetti stated that the results from the Science paper suggest that XMRV is not very
      active in T and B cells in the peripheral blood – the main players in the adaptive immune response.
      His study looked further into the immune system and found that it can infect two major players in the innate immune response
      - monocytes/macrophages
      and antigen presenting dendritic cells. Interestingly, while XMRV appears to be able to
      infect and replicate in these cells, MLV’s cannot – the reason being that
      they cannot infect ‘non-dividing cells’. Ruscetti is currently investigating whether XMRV is
      infecting a small number of macrophages/dendritic cells that are dividing.

      XMRV and the immune System - MLV’s have a history of producing cancer and neurological disorders in rodents and other
      mammals but what about those immunologically disturbed ME/CFS patients? Does XMRV do anything to disturb the
      immune system? This study, which looked at how the gene expression in prostate cells changes when they
      become infected with the virus, found a good deal of abnormal immune and other gene expression. The authors
      stated their findings suggest the virus could have a ‘profound effect’ on fundamental cellular physiology
      and inflammation.

      XMRV and EBV Team Up?- a Spanish team found that XMRV in a significant percentage of EBV transformed (infected?) Cell Lines from
      a small group of ME/CFS patients and healthy controls suggested that EBV infected B cells could be a tissue
      reservoir for the virus.

      XMRV Present in Leukemia and Mantle Cell Lymphoma Cells - Dr. Mikovits and Dr. Ruscetti and others found XMRV in
      leukemia and Mantle Cell Lymphoma cells from two patients. The abstract suggested that the development of these
      cancers ‘coincides’ with three factors; the growth of the gamma delta T-cells,
      XMRV infection and a ‘distinct inflammatory profile’. They appear to suggest
      that these
      factors could place patients at risk for the development of
      these cancers. (Interestingly, neither EBV, nor HHV-6 or CMV appeared to
      coincide with cancer development). They also noted that antivirals can help in
      HIV derived cancers and that AZT and Raltegravir stopped and significantly reduced previously
      rising lymphocyte counts in one XMRV infected ME/CFS patient with cancer. This
      suggests antiretrovirals may be helpful in this set of  ME/CFS cancer patients.

      Dr. Cheny (ahem Cheney’s) Study – Dr. Cheney’s study probably did little to answer any of the more pressing questions about XMRV because the
      tests were not done at an independent lab but it should prove quite valuable
      when the WPI’s XMRV test is validated. Some of his stats were alarming. Dr.
      Cheney has said he probably sees a sicker population and judging
      from this sample he probably is; the average duration was almost 20 years! He found XMRV in almost 75% of them. Just as the Phoenix Rising Forums
      his patients had a very high incidence of CFS or CFS-like illnesses in their family (45%); 48% had cancer in their families or
      themselves and 28% had autoimmune diseases in the family. (One wonders what the norms are.) The most startling fact was
      50% XMRV positivity in non-CFS family members. If Dr. Cheney is right this virus is spreading in families.

      XMRV Positivity Rates at VIP Dx - In the 7 months between November and May VIP Dx Labs
      received 712 samples (about 100/month) from 46 of the 50 states in the US and about 50 from Europe and the UK.
      Of those only 35% tested positive for XMRV. The discrepancy between Dr. Cheney’s 75% and VIP Dx’s 35% is surely
      one reason why Dr. Mikovits stated the type of patient being tested is a major
      factor in the positive rates for a test. Of course, Dr. Cheney with his 20 year
      ME/CFS patients was undoubtedly testing a severe subset. We’ll have to wait for
      more comprehensive testing of ME/CFS populations to determine just what type of
      ME/CFS patient tests postive…It will be fascinating!!!

      Children with XMRV - the Ruscetti/Mikovits juggernaut rolled
      on with their (fourth?) abstract, this time
      indicating that XMRV was present in no less that 82% of 17 autistic children (!) The finding that 16 of the 17 families with
      autism spectrum disorder, CFS, FM, Lupus, etc. had at least one member infected with XMRV suggested that it
      may run in these diseases, although, of course, much more work needs to be done.

    Sept 21st

    • XMRV International Workshop Abstracts Part I - the abstracts are not the video’s – they should be out soon – but they do give essentials
      about the talks and they are INTERESTING. 

      Those Monkeys - Five Rhesus macaques were infected with XMRV; two of them were sacrificed quickly and the others
      several months later. Creating only low levels of antibodies, the immune system did not react strongly to the virus possibly because
      it was able to quickly remove the virus from the bloodstream. This apparently suggested to the investigators that the
      virus showed low infectivity and virulence, but low and behold when they opened the animals up, they were surprised to find that the
      virus had infected many organs and they were able to detect evidence of ongoing replication. Interestingly, the virus hung out in the lymphoid
      organs – which give it a clear pathway to the bloodstream. (Dr. Mikovits has suggested that the lymphoid organs could be a
      tissue reservoir for the virus). They found that XMRV was also replicating in all the sexual glands
      - which, of course, suggests that sexual transmission is a distinct possibility.

      XMRV is Different in the Prostate (and the Prostate) – we’ve heard that different XMRV variants may exist in the blood and the prostate but
      this study suggested that the XMRV may be different within the prostate itself. This study found different forms of XMRV which, the
      authors speculated, could enhance XMRV’s ability to cause prostate cancer (if indeed it does that).

      XMRV Is Not Present in Prostate Cancer in the US - While several positive prostate cancer XMRV studies
      have occurred this fairly large John Hopkins
      study, which used immunohistochemistry, found zero evidence of XMRV in almost 200 samples…But…

      XMRV IS Present in Prostate Cancer in the US
      - a Baylor study found XMRV was present in 22% of 144 prostate cancer patients -
      so much for consistency at this stage of the game. Still a positive report
      should trump a negative one, all things considered.
      Two more US studies will alternately not find and find XMRV in prostate
      cancer patients.

      Hanson XMRV CFS Study Strongly Positive - This is the first study
      to use LnCap Cells (aka WPI) to culture at least some of the blood samples.
      Reports from the conference suggested that Dr. Hanson found polytropic MLV’s but
      no XMRV but her abstract stated her
      study was strongly XMRV positive with XMRV gag sequences showing up in just over half the CFS
      patients. The abstract ends “Our results corroborate those of Lombardi et al (Science paper)”!
      Dr. Hanson is the first recipient of an NIH grant to study XMRV in CFS patients
      and her extensive study to examine the immune factors and the effects of exercise on
      XMRV is projected to take at least a year.

      Yes, There is XMRV in the UK (and Quite a Bit of It!) - This UK study with Dr. Mikovits in the lead and Dr. Ruscetti the senior author, states that ‘more sensitive’ methods to detect XMRV have
      been developed since the
      Science paper was published last October. The blood was collected in England and shipped to the National Cancer Institute in
      the US. They came right out and said it’s not about the methods – that the most important factor in the negative results in the type
      of patient studied (eg, “It’s the patients stupid”) a theory which seems to
      have gained some strength lately. The paper states  “Since the most important variable in detecting XMRV
      in CFS is patient selection” – an interesting statement, if there ever was one.

      They used five methods, the most prominent of which was culturing in
      the LnCap cells that Dr. Hanson used but they also used
      antibody tests and various kinds of PCR tests on different types of cells. The WPI has been
      working hard on the diagnostic end as they cited their new antibody tests and new primers that can detect both
      XMRV and polytropic MLV env sequences. They also showed, as did the Science paper, that cell free media
      from patients contained the
      virus (it was present in the blood outside of the cells) and that the virus
      could infect other cells once they were placed in it; no wonder Dr. Ruscetti reportedly claimed
      his work on the diagnostic end was over and he was moving onto the next stsge of research. This was a very strong study – with multiple
      overlapping tests – just as occurred in the original Science study.

      A New Method For Detecting XMRV - God knows what this technical
      abstract means but apparently Dr. Ruscetti has has developed ‘DERSE’ cells that
      can quickly and sensitively detect the presence of XMRV – another diagnostic
      improvement in a Workshop that was chock full of them.

      ‘High Throughput’ Antibody Tests Available - want to test large quantities of blood for antibodies to XMRV? This abstract, if I read it
      right, states the authors think they can now do that.

      Blood Working Group Has Been ‘Working’ – Not very fast but they are working. They are now very
      clear that they have a good test to detect XMRV in spiked vs unspiked whole blood, PBMC’s and plasma. Next step is
      looking for XMRV in people!

    Sept 18th

    • Dr. Deckoff-Jones Talks-there’s lots of stuff to consider in Dr. Deckoff’s latest blog
      on why the antivirals seem to be working for her and her daughter but not in
      some others. As always she takes an admirably sober look at their treatment
      situation. She does not recommend that anyone take
      these drugs unless they are under a doctors supervision. She notes the risks of
      going on a possibly less than optimal drug regimen since we know so little about
      the virus at this point and how doing so is a personal decision. (Taking
      antivirals in the wrong combinations can imperil the effectiveness of later
      treatments). She also believes anyone who starts to take antiretrovirals should
      be prepared to be on them permanently. 

      She provides her entire treatment regimen and notes how
      effective a treatment called “Actos” which assists with insulin sensitivity and enhances ovulation and
      progesterone levels has been for her daughter,
      for whom she says it has been ‘quality of life-changing’. Given XMRV’s androgen
      sensitivity there was some concern about the effects of a progesterone enhancer but Dr. Deckoff, herself, is taking testosterone and both of them
      feel better. Dr. Deckoff’s statement about endocrinologists
      “Endocrinologists as a group seem to be particularly clueless with respect to managing CFS/Lyme patients,
      even though hormone depletion is probably pretty universal.”, in my experience, is apt.

      This blog is loaded with information -far more than could be covered here. Let’s just end with
      her summary to date of her and her daughter’s progress; “All I really know for sure is that
      we are X+, we’ve been on antiretroviral treatment since March, on three drugs since May
      and we are a lot better. Lyme Disease was a big piece for Ali, probably not for me. We’ve
      each gone up at least 30 KPS points since starting HAART. I don’t think it’s possible that
      antiretrovirals haven’t helped us. Nothing else we’ve tried in the last few years has
      worked, except for Deplin and Ali’s Actos, and I think we can all agree that we were
      unlikely to get this kind of improvement from those interventions. But it is possible that
      the other things we are taking are potentiating the effects of the drugs or ameliorating
      the side effects of treatment. Neither of us feels completely well, especially me.
      But we are both hugely more functional. We can only hope it continues.”

    • Lancet Takes New Tack
      (?) on ME/CFS
      - The big 180 year-old British medical Journal Lancet surprised with
      a new more viral-based slant on ME/CFS. The editors put two and two together and reported that a recent
      study finding increased rates of oxidative stress and white blood cell apoptosis in adolescents with
      ME/CFS suggested a viral infection was at work. 

      Lancet was on shaky ground suggesting that most people who get ME/CFS following
      infectious mononucleosis eventually recover but then they went on to state that
      ME/CFS was mostly likely caused by pathophysiological problems – a remarkable
      statement coming from this journal. They backtracked a bit on that statement
      citing the uncertainty about the physical-psychological interactions in ME/CFS
      but then argued that research into the disorder should receive ‘high priority.’

      Phoenix Rising Forum members found little to like about the editorial but I thought it presented
      a major step forward for this particular publication.
      Check it out here.

    • Nevada Newsline Interviews WPI Vice President Mike Hillerby and Dr. Vincent Lombardi

    - After noting that the response from the last radio program was off the
    charts Nevada Newsline brought Mike Hillerby back. Mike called the number of
    calls and emails he receives almost frightening given how many desperate and
    untreated people they indicated are out there.

    How it all it got
    started
    -  Dr. Lombardi explained just how XMRV/CFS connection got
    started. As with many notable discoveries the process was amazing. Dr. Lombardi
    was already looking at RNase L (his was the only lab in the US to test for the
    RNase L defect in ME/CFS) and was interested in prostate cancer and
    contacted Dr. Silverman. While they were at a prostate cancer meeting they ‘threw around’ the idea of
    looking for XMRV in CFS patients – something he felt was a kind of ‘pie in the sky’ idea
    at the time given how different the two disorders were. Some time later, a
    graduate student came into the office
    asking for something interesting that  he would do it for free… at which
    point, Dr. Lombardi, stating that he’d promised Dr. Silverman he’d get the
    testing done,
    gave him the samples….and off they went! Soon after that the samples starting
    turning up positive. Such were the humble beginnings of this major discovery :) .

    Dr. Lombardi proved to be an interesting speaker and he soon said something very
    interesting – that XMRV has the ‘highest correlation’ of any marker that’s been
    found in ME/CFS…. and he would know. As the head of the (former) VIP Dx Labs -
    he regularly tested all sorts of markers in CFS. The fact that XMRV shows up in
    a higher frequency of people with ME/CFS than anything else is notable; that, in
    itself, is a strong argument that it plays a key role in this disorder.

    Mike Hillerby noted that they are getting better and better at learning how to find the virus and that their
    test is becoming more and more reliable over time. The Symposium that occurred immediately after the WPI’s opening was targeted at clinicians
    was targeted at such things as having physicians track which immune parameters
    were being disturbed by XMRV.  Mike Hillerby said they felt the clinic will be open by the end of the year.
    One patient caller noted how phenomenal Dr. Peterson had been in helping him.

    Discrepancies in Research Studies - Dr. Lombardi feels that different patient cohorts may very well explain
    many of the differences between the studies. Mike Hillerby noted the presence of subtle genetic sequences in MLV’s have
    probably
    played a role as well. About 85% of ME/CFS patients with well characterized CFS have
    tested positive at the WPI.

    What about Fibromyalgia? - Dr. Lombardi stated they had seen some FM
    patients with XMRV and fit it into the same neuro-immune disease category as
    ME/CFS.

    As before Mike Hillerby proved to be an superb spokesman for the WPI
    and seems to be able to seamlessly deal with just about any topic. There is much
    more in this 50 minute interview -

    • A Time
      To Act
      - Today is several times; it’s Sept 14th, for me personally it’s 3
      days after my birthday, it’s 4 days after the WPI Gala Fundraiser, and 327 days
      since the WPI published their paper that turned the ME/CFS world upside…but
      what time it really is, I think, is A Time to Act. I believe we have an
      opportunity present to us right now that may be unique and which, if skillfully
      used, could propel us further than we have ever gone before. Our tipping point -
      the point at which we give a small nudge that ends up changing everything -
      could be upon us. Check it out in

    • Dr. DeMeirleir’s poster on XMRV from the Workshop
      - Dr. DeMeirleir reports
      the presence of reduced CD3 T-helper cells and CD57 lymphocytes and higher C4a,
      soluble CD14, serum IL-10, and elastase activity  The sample was very
      small, unfortunately (16 patients) but the findings are intriguing. T helper
      cells are wiped out in HIV/AIDS and Nancy Klimas appears to be finding reduced
      cytotoxic killer cells (CD57) in ME/CFS. These are two of the big guns in the
      adapative immune response – while they were different from controls they were
      still within reference values; they were not ‘shot’ as you see in HIV/AIDS.
      It was good to see increased C4a since it has been implicated in the
      post-exercise problems in ME/CFS before. Elastase could interfere with a number
      of things including blood vessels and it has been implicated in ME/CFS as well.
      Other findings were found. Dr. Mikovits has reportedly identified an immune
      signature and it will be interesting to see how the two signatures match up.

    • OFFER Conference - I just got back from the OFFER Conference. I’ll do a more formal report later but some tidbits
      I got from talking to Dr. Singh and Dr. Vernon. 

      A Researcher with Culture :) – At least part of Dr. Singh’s study is a direct replication of the
      WPI’s efforts – she is (very carefully) culturing the virus. She said that she
      felt researchers should concentrate on the most ‘sensitive’ methods of detecting
      the virus that were described in the original paper – and that was clearly
      culturing – so that’s what she’d doing. To my mind she basically inferred that researchers that were not doing that were not giving the
      authors of that paper a fair shot. The problem with culturing is that it takes six to eight weeks
      to culture the virusu and its expensive and labor intensive.

      She’s not
      surprised at the difficulty researchers are having. She has been studying XMRV for FOUR years and a relative of it
      (Moloney Murine Leukemia Virus) for 10 years – she knows these are tricky viruses.

      I asked her if she was having more or less trouble with XMRV than with the
      Moloney Virus and she said  it was
      about the same for both. She could not see any way the WPI’s or Dr. Alter’s
      results could be due to contamination.

      An Excellent Study – Both Dr. Vernon and Kim McCleary have spoken of her
      study in the highest of terms. She is being extremely careful with blood
      handling and her test protocols and she is using fresh blood. With 200 healthy
      controls in hundred and five CFS patients it’s a very large study and she is
      using multiple methods to detect it including qPCR for proviral DNA, RT-PCR, two
      types of antibody tests in the culturing. She was in anyin an andShe is building on
      past studies and filling in the gaps. She noted, for instance, that the samples
      in the healthy controls and CFS patient samples in the original Science study
      were handled in different ways and that while the patients came from across the US all the healthy
      controls came from Maryland. (In one of those odd coincidence’s all of Alter’s healthy controls
      also came from Maryland as well.)
      This is not to knock the original study; all studies have their weak points but to illustrate that all studies, should,
      as Dr. Bateman pointed out build in each other. Dr. Singh’s patients and controls will come from the
      same area and the blood storage methods will be identical for both. This will control for differences in blood preparation
      and geographical variations in viral persistence and in viral sequences.
      Importantly, with the help of Dr. Bateman, she is also breaking up the patients
      into three cohorts depending upon severity.

      The XMRV Autopsy Study Is Wrapping Up – She has been working on the XMRV autopsy
      study for THREE years. She started it in Columbia and was able to bring it (and
      her entire team) over to the Univ. of Utah. (Think of that! Her entire team left
      the intellectual backwater that is Columbia to move to that paragon of medical research- the University of Utah
      :) :) ; she obviously inspires alot of loyalty in her team members). (Let’s hope they were
      just shipping slides not corpses). She has been taking samples of every organ in the body, putting it on a slide, and then examining it for evidence of XMRV using her
      Immunohistochemistry protocols. (These cause XMRV infected cells to be highlighted.) The exciting news is that the study will be done in the next month and should be published some time around the New Year. I asked if the fact that the XMRV was a hot topic would speed up publication? She said because every journal is afraid of being wrong on a hot topic it would slow it down.

      That Rare, Rare Virus - I asked her if a really rare virus could cause such signficant effects as ME/CFS? Did researchers need
      to find it in higher levels somewhere else for it to really be doing something? She said ‘No’ and referred to another
      retrovirus, HTLV, that she believes could be a model for XMRV. HTLV clearly causes leukemia in some people
      but even in those people its found in very low levels.  Interestingly, only causes leukemia in a subset of the people that it
      infects. Why it causes leukemia in some people but not others is unclear.

      Can XMRV cause disease if it’s not replicating? - she noted that several viruses cause cancer
      simply by inserting themselves next to oncogenes in a cell’s DNA. I asked if XMRV could disrupt another type of gene simply
      by settling down next to it. She thought that was a possibility but couldn’t come up with an instance in which
      that had happened with another virus.

      Treatment Trials - Dr. Singh again brought up the possibility of treatment trials and even outlined some
      paramters and named two companies
      she is in very preliminary discussions with. We know she’s gotten some results back from her study. Does the fact that she’s mentioned the possibility of treatment trials twice now tell us anything about her results? We’ll
      find out in a couple of months!

      Name Change – Will we be getting a formal name change? She
      doesn’t think so; for one thing the original discoverer is in charge of naming a
      virus and two, she imagined there would need to be much
      more consensus on the virus before one would occur.

    • Dr. Vernon at the OFFER Conference - Dr. Vernon’s Ph.D was in virology,
      interestingly enough. (It was interesting watching her question a patient about
      his infectious onset. He presented with an huge swollen gland in the groin area.
      She asked did they test for bubonic plague (it is present in California)?
      When they diagnosed toxoplasmosis but could not find an antibody to it she
      said it might have been a Protozoa with a similar structure then asked if they
      gave him antimalarial drugs? She clearly knows her pathogens. 


      Infectious XMRV and non-infectious MLV’s?
      - MLV’s have been well studied but not because
      they’ve been found to infect humans; they are found in other mammals (dogs and cats, for instance) but, if I got this right, no one has
      ever been able to culture MLV’s from humans. So we have a bit of a dichotomy, a clearly infectious XMRV and a not clearly infectious,
      at least at this point, group of MLV’s. (Dr. Alter is reportedly trying to code the MLV’s he found.)

      The Director Drops In and Stays…. – Dr. Vernon was astonished to see the
      Director of the NIH drop into the XMRV International Workshop and then STAY. She said he was there in the front row and asking
      questions for 75 percent of the Workshop. She has been to many many conferences over the years and she’s
      never seen that before.

      The Lipkin-ME/CFS Connection - is much stronger than we thought. She appears to have known
      Dr. Lipkin for quite some time; she said he first came across ME/CFS patients in the early 1980′s and that
      he’s always thought CFS was caused by an infection. Dr. Lipkin is also collaborating with Dr. Montoya
      on his broad look at pathogens in ME/CFS. The Columbia ME/CFS connection is certainly intriguing; there’s
      Dr. Lipkin, Dr. Singh (before), Dr. Racaniello and Dr. Goff.

      Putting ME/CFS on the Map - Dr. Vernon is excited about XMRV and doesn’t know how
      it’s going to turn out but she is clearly very happy about how it has put CFS on the map; she clicked off
      the number of powerful groups that are interested in ME/CFS because of XMRV; the NIH, Red Cross, big Pharma, CDC and FDA. She
      thinks it has engineered a the most fundamental change in how ME/CFS is viewed.


      ‘Look Back’ Study
      - CFIDS Association of America is working with the Red Cross to do a
      ‘Look Back’ study to examine old blood stocks and help determine if or how much XMRV is transmissable
      through the blood.

    • Dr. Racaniello Talks - Coming back from vacation, Dr. Racaniello talked about
      Dr. Alter’s paper. After noting that it provided “support for the involvement of murine retroviruses in CFS”
      he stated Dr. Alter’s ability to find MLV’s in the same patient 15 years later was ‘important’. He felt
      the most important finding was the discovery of the polytropic MLV’s. He, like Dr. Vernon, described them
      not as ‘variants’ of XMRV but, despite their genetic similarity, as entirely different species. He noted that
      XMRV is a combination of polytropic and xenotropic viruses (while the MLV’s are all polytropic). (We’ve heard
      how much these viruses like to intermingle). 

      Dr. Racaniello then echoed Dr. Mikovits argument that researchers focus on a narrow slice
      of
      the genome “could, in part” explain their inability to find murine leukemia viruses in ME/CFS.
      Then he suggested that the
      ability of Alter/Lo group to ‘readily’ find MLV’s in both plasma and blood
      suggested that the WPI might need to adjust their primers as well, since that indicated culturing is not necessary
      as the WPI proposed. (Dr. Mikovits, of course, has stated that the WPI long-ago
      found these ‘variants’ or what Dr. Racaniello and others firmly refer to as
      similar viruses but separate species.)

      Different Primers - A comment on the blog by Jacqueline was intriguing. She noted that nowhere
      in the original paper did it state that culturing was used in the PCR (which is
      true – the PCR test in the original paper did not
      use culture; another part of the paper did. In fact in their official statements
      the WPI has never said that culture was absolutely necessary; it’s simply the
      most ‘sensitive’ way of finding XMRV at this point). After taking a close look
      at the ‘inner’ primers the Alter and WPI groups used she found a small
      difference she felt might explain why the WPI missed the MLV sequences (if, in
      fact, they did) but did not explain why Alter was unable to pick up XMRV. Dr.
      Hansen, reportedly, also found polytropic MLV’s but no XMRV in her samples.
      Meanwhile, of course, we had some studies pick up XMRV….it’s clear that we’re
      in a (rapidly, although it doesn’t seem that way) evolving field and that these
      issues will get cleared up over time. The most important conclusion of the Alter study was that, just as in
      the WPI study,
      murine leukemia retroviruses were highly associated with ME/CFS and not with controls.


    • Jacqueline’s Blog
      - Jacqueline is a medical librarian with some experience
      in this field. She’s written a series of rather technical blogs on XMRV. Warning
      - she’s not been particularly happy with the WPI, in fact, she’s not
      particularly happy with anyone (although she did like the Alter paper); what she
      offers is a deeper dig at the technical aspects of the studies than most
      bloggers offer.

    • XMRV Workshop
      Q & A Transcript
      - (Somehow)Global Action managed to
      get together a
      Transcript of Q & A sesion at the Workshop. (How do you do that from a
      live feed??) However,they did it they did it quickly and well.
      Check it out here.
    • No ‘Flip’ Yet - The Workshop did not out to be the place where the
      research world flipped from worrying about how to find the virus to figuring out
      what it does and how it does it. According to one report Dr. Ruscetti said he,
      at least,
      was turning his
      attention from diagnosis to pathogensis but it was clear that many others were
      not. The Q&A session revealed a hard-nosed bunch of researchers who want to get
      matters nailed down before they move on. The NCI chiefs response to Dr.
      Ruscetti’s question about more funding (none planned) indicated that the
      Institute was waiting for the testing issues to get ironed out before it would
      as well. Indeed, the second really major bit of positive news (see below for the first), thus far,
      to come out of the Workshop was the creation of another diagnostic task force
      under the direction of an ace pathogen detective Dr. Lipkin. XMRV continues to be hung up – at least in
      the views of many of these researchers – on the horns of the disparate PCR
      results. 

      Slow Progress – Dr. Stoye had hoped to have answers by now.
      With three more negative and three positive studies reported Dr. Coffin
      stated “we�re still in a zone of chaos where…. we don�t have agreement on
      almost anything in this. We have to work toward that right now”

      Interestingly, Dr. Coffin tried to damp down what he appeared to feel were
      overly exuberant expectations of success, stating that he felt, at this
      still early stage of the game, that things were moving about as expected.
      “It�s really quite a short time. It takes a long time, to set up, say to set up
      the blood working group panel, it�s been probably six months of talking and deciding
      and so on before we began to get samples really in� so it�s only couple of months that
      we�ve been working on that. So I�m quite optimistic that say
      within the next year there will be a synthesis of this to
      the point where not necessarily everyone�s using exactly the same assay” Others felt results would appear
      more quickly. Dr. Stoye, in fact, expected to get results ‘very, very quickly’ (whatever that means
      in
      ‘researcher time’!) and others have stated they believe the Blood Working Group to have some standardized assays
      ready by Christmas.

      Dr. Mikovits argument that the human retroviruses have been, in the early stages of
      our understanding of them, difficult to assess using PCR and that antibody tests
      are more appropriate appeared to fall on deaf ears – at least in that group. Dr. Sing, however,
      noted how difficult it was to get human papillomavirus (not a retrovirus) nailed down using PCR, and yet how much progress they made
      when they finally did do that: “if we look at the HPV research, in the early age of
      HPV research, there was a struggle of HPV detection and once that was validated and
      clear, there was tremendous progress in HPV research and then there was the HPV vaccine development”.

      ME/CFS Patients Being Undercut? -
      Dr. Mellors, the Chief of Infectious Diseases at the Univ of Pittsburg, felt that
      ME/CFS patients concerns were being undercut by a Blood Working Group focused
      mostly on the safety of the blood supply. He argued that a much more extensive testing
      procedure involving
      a neutral party disseminating samples to multiple laboratories using their own
      methods should be underway. (This appears to be identical to what Dr. Enlander has proposed
      and is reportedly working on) Dr. Holmes of the Blood
      Working group stated they were getting all their samples from the WPI but that they were
      from a wide geographic area and Dr. Mikovits backed him up on that. Dr. Sing
      agreed on the need for more widespread testing and also descried the inability of
      the research community to work together (something the research community has been descrying
      about itself for about six
      months) stating “All of this is dependant on highly accurate, sensitive,
      specific assays. So some sort of coordinated effort among these laboratories using different assays, different platforms, I think
      that will make tremendous contribution to the
      field of XMRV research. So I really encourage you to work together…some kind of collaboration and coordination I think would really make
      this field move forward much faster, and I am looking forward to that.”

      THE ANSWER is At Hand? - In response to a question about the effects different
      ‘collection and storage’ techniques might have had on study results, Dr. Mikovits
      jumped in with an answer that threatened to make many of the questions asked
      above moot.  It seems that just in the past few weeks, no doubt spurred on by the
      Alter/Lo findings, that the Blood Working Group may have uncovered a key problem plaguing some of the
      negative studies: “we have learned literally in past 2 wks in the BWG that
      processing may be a key and we may have found an opportunity to have a processing
      protocol where everyone would
      at least find viral RNA in plasma and blood products without culture.”  What
      an odd thing if something as simple as ‘processing’ problems (blood handling and
      storage?) were at the heart of all this mischief.  Somehow, however, the discussion veered off onto
      another tangent after Dr. Mikovits startling response and we heard no more of this!

      Treatment Trials - a good part of the Q&A was taken up on the treatment
      trial question with Dr. Coffin and Dr. Stoye coming out strongly against even
      small treatment trials until they had found a way to measure viral load using
      quantitative assays. After at first refusing to be drawn into the question of
      the validity of anti-retroviral treatments by a question from Hilary Johnson,
      (Dr. Mikovits is not a physician) Dr. Mikovits later argued they could learn
      alot now from treatment trials using immunological measures. Of course treatment
      trials in CFS always use accepted qualitative clinical measures of
      functionality, etc. and there are several of them but they are apparently too qualitative for the virologists at that table.

      Mindy Kitei started off the first clinical trial question section and then came back again later, questioning
      whether certain groups really wanted to find the virus. She pointed out that the
      CDC used the same German research unit to validate their results that was unable to find XMRV in prostate samples…(Hmmmmm).
      She asked – why not send them to the Cleveland Clinic instead…which seemed a
      reasonable question but the implications of it disturbed Dr. Stoye greatly,
      leading him to respond “I think we�ve heard enough of this particular line of questioning. I think nobody in
      this
      business is trying to get a negative result � it�s in nobody�s interest.”

      Really, they both have their points. It’s
      certainly not in the interests of Dr. Wessely or Dr. Kuppeveld or the CDC CFS
      Research group to find a retrovirus. On the other
      hand it’s entirely in the interests of retrovirologists to find one whether they work at the WPI, the CDC’s
      HIV division or
      elsewhere; another human infectious retrovirus (there are only two others) is huge news for their field.
      Now that some retrovirologists have staked out their ground on XMRV issue, of
      course, we have a different set of
      conflicts to worry about…..

      The Cohort Question Again (and again and again) – One physician asked how accurate diagnoses can be based on
      physicians that may either place patients ‘in’ or ‘out’ of ME/CFS based on
      subjective criteria. Dr. Mikovits agreed stating that if “you look for various immunological defects rather than just subjective defects” you get better results. It was the
      idea of an immunological abnormality ‘filter’ that raised so much ruckus in the
      Science study. The WPI backed off on those stating those immunological
      abnormalities were not
      a requirement and now here
      they are again. Both Dr. Mikovits and Dr. De Meirleir, interestingly, stated they’ve found immunological signatures in
      XMRV infected patients; it’ll be very interesting to see what they are.

      The Lo/Alter Results - Dr. Coffin readily acknowledged the validity of the Alter findings but
      was careful to ensure that everybody realized that the only virus that has actually been
      captured and sequenced is XMRV stating “I think before we start referring to a bunch of different viruses we really need to have viruses that go with those sequences. We can say there are sequences there that look like endogenous MLV�s, maybe a little bit different
      from them. But we just don�t have a virus yet to go with them.” He agreed that Dr. Lo’s may have
      been on to something when he suggested that the CDC and other groups were unable to find
      the MLV’s because they were using a ‘leader sequence’ that didn’t match up with them. Looking at that
      will help clear up whether other MLV sequences are present are ME/CFS. Dr. Alter/Lo are in much the
      same place Dr. Mikovits, Dr Ruscetti, Dr. Lombardi and the Cleveland Clinic were in a year and a half
      ago when they had sequences but not a complete virus. Dr. Alter is reportedly trying to culture the
      MLV’s they found in their study and completely sequence them.

      Funding, Funding, Funding - Dr Ruscetti reminded everyone that a little thing called ‘funding’ was necessary
      to carry on this work – something he’s clearly worried about – stating ” But what
      fuels that is a practical thing called funding. So you�re involved in the extramural program of the NCI.
      What would it take for the NCI to increase funding in this area” and getting that standard response from
      someone who must, at least in some manner, be his boss: yes, we’re all so interested in this subject and
      isn’t it great that we’re having this workshop (doesn’t that demonstrate our interest?) and then stating that no’
      new funding directly devoted to XMRV will be coming until the testing problems are clarified. In fact, even then
      then all he would say was that he ‘suspected’the NCI would then’look’at the issue: “As things develop and it becomes a little clearer
      what�s going on I think then certainly I would suspect that the NCI and NIH are
      going to look and see if there are things
      that would be appropriate to do – and if the money is available.” Interestingly, he said the NCI has not had
      alot of grant requests, something an audience member suggested indicated that researchers are not willing to put alot of effort into
      a subject they still have questions about.

      Dr. Coffin echoed the fact that the NCI has not put a dime of intramuural funding into XMRV, forcing researchers to
      divert their own resources into exploring- something that says something very special about
      researchers and the
      system they work under – but which also has its limits.

      NCI has not put any extra $ intramural money for this purpose � yet an enormous amount of work has been done
      and a lot of funds have been diverted by all of us from our previous projects into this area. I think this is remarkable testimony to the resilience of American, European, international science, that, in fact that
      we can do this without the necessity for instantaneous top-down funding. However the momentum on this will tend to run out after a bit without additional money being put into it at some level or another.
      So it�s very important to sustain the momentum that we have so far.”

      Why is it So Darn Difficult? – Dr. DeMarzo at Johns Hopkins asked
      why, if XMRV plays such a central role -it was so darned difficult to find using
      all this ultra-sensitive PCR technology? Dr. Mikovits suggested that
      it wasn’t that surprising at all investigators should rely on
      ‘complementary methods (eg serology (antibodies)). Dr. McClure said she’d happy to grow the virus
      if she could find it but she couldn’t find it using PCR or serology and then “I don’t know
      what else we could do” which was a kind of amazing statement given the Blood Working Group
      and others appear to
      have found lots of ‘other things to do’. Dr. Ruscetti then cut in, making Dr. Mikovits’ point -
      that you cannot rely on PCR alone – in even stronger fashion stating “Negative PCR is not
      a stand-alone assay for detection of this virus in clinical samples.” Nothing was resolved in that little exchange which
      threatened to get hot and the room moved on.

      The Disease Causes the Virus”?
      During a question about immune abnormalities Dr. Coffin made the interesting
      suggestion that the virus is present in everyone and that the disease allows it to show up in more sickly people.
      “I mean it�s still possible to entertain the idea that the disease causes the
      virus, and not other way around in a sense… or makes visible a virus that�s
      actually very prevalent, but it�s really such a low level in some, couple of
      cells somewhere in people, it only comes up because of the conditions
      surrounding these diseases.”This is a question that can only be resolved with
      validated assays and more testing in more disease groups.

      Dr. Mikovits, however, noted that the envelope of gammaretroviruses produces
      neurotoxins and that the HIV retroviral model – one retrovirus knocking down a
      part of the immune system – causing pathogens to flourish, fit ME/CFS pretty
      well.

    Sept 8th

    • Workshop News - The Workshop continues to scintillate….More evidence
      that the NIH is getting involved; the Director of the NIH, Dr. Frances Collins
      kicked off the Workshop – that was news – and then apparently left but is
      back….in a front row seat viewing the CFS section…
    • A negative study deciphered? Huber’s negative XMRV study came under some
      question because of speculation her use of ‘hepanarized blocks’ might have
      blocked her ability to find the pathogen.
    • A positive study explained? – Dr Lo apparently held forth on ‘several
      conditions’ that could have impacted other researchers ability to find the
      virus.
    • International XMRV Workshop Exceeding Expectations - In terms of impact on policy the International
      XMRV Workshop is exceeding expectations. The big news is that the NIH tagged
      NIAID Chief Anthony Fauci, himself, to oversee a major study on XMRV and CFS.
      Anthony Fauci is a major, major figure – he is the HEAD of the NIAIDl
      (National Institute of Allergy and Infectious Diseases) – and
      his appoinment indicates what a hot-button issue the NIH believes XMRV in. Dr.
      Mikovits has complained how the NIAID has ignored XMRV thus far….well, they’re
      not ignoring it any longer. By appointing Fauci they are attempting to
      demonstrate to the world how serious they are about the subject 

      Anthony Fauci,
      however, has been no friend to ME/CFS – in fact, he’s been considered a major
      problem for years. He headed the NIAID when ME/CFS
      was kicked out of the Institute ten years ago, an event which lead to years of
      research declines as the program slowly disintegrated in the backwater that is
      the little Office for Research on Women’s Health and he has been utterly
      resistant to attempts to increase funding.

      But Anthony Fauci did a
      very interesting thing when he turned the research project over to Ian Lipkin
      at Columbia University, an ace pathogen detective, who was already rumored to be
      studying XMRV in ME/CFS. When asked by Amy Dockser Marcus why the conflicting
      results thus far he cited different types of patients, sample preparation and
      methods. His study will include testing samples from different areas of the
      country at the WPI, FDA and CDC. Here’s some info from the Marcus article

      The new study, Lipkin says, will involve fresh blood samples from 100 CFS patients and 100 similar,
      but healthy people � 25 of each group from four different sites around the country, to provide
      geographic diversity. The samples will be processed, blinded and sent to the FDA, the CDC and the
      Whittemore Peterson Institute, which led the team that published the original Science paper. If a
      lab finds a sample is positive for XMRV, further tests will be needed to confirm the result. If one
      lab finds a positive sample but another lab doesn�t, the same samples can be shipped again, with a new blinded
      code, to be tested again. �If you get the same result, it is valid,� Lipkin says.

      Ian Lipkin – who is Ian Lipkin? Ian Lipkin is a pathogen hunter who has tracked down some of
      the ‘hottest’ pathogens of recent years including the West Nile Virus and SARS. More importantly
      he is known for his creation of cutting edge techniques to uncover new and emerging pathogens. In short, he is the ‘tip of the spear’
      in pathogen discovery – the man they send out get a hold of new bugs. He’s also
      heavily involved in viruses that effect the brain and in autism. One of the premier pathogen hunters on the planet,
      his appointment indicates the NIH’s has finally gotten serious about XMRV….
      This is what you would expect when the top retroviral Institute in the world
      gets moving. Here’s from Wikipedia on Dr. Lipkin:

      A physician-scientist, Lipkin is internationally recognized for his work with West Nile virus and SARS, as well as advancing pathogen discovery techniques by developing a staged strategy using techniques pioneered in his lab. These molecular biological methods, including MassTag-PCR, the GreeneChip diagnostic, and High Throughput Sequencing,
      are a major step towards identifying and studying new viral pathogens that emerge locally throughout the globe.A major node in a global network of investigators working to address the challenges of pathogen surveillance and discovery, Dr. Lipkin has trained over 30 internationally based scientists in these state-of-the art diagnostic techniques.

      Lipkin is the Director of the Northeast Biodefense Center, the Regional Center of Excellence in Biodefense and Emerging Infectious Diseases comprising 28 private and public academic and public health institutions in New York, New Jersey and Connecticut. Within this consortium,
      his research focuses pathogen discovery, using unexplained hemorrhagic fever, febrile illness,
      encephalitis, and meningoencephalitis as targets. He is the Principal Investigator of the Autism Birth Cohort, a unique international program that investigates the epidemiology and basis of neurodevelopmental disorders through analyses of a prospective birth cohort of 100,000 children and their parents. The ABC is examining gene-environment-timing interactions, biomarkers and the trajectory of normal development and disease.

      Lipkin also directs the World Health Organization Collaborating Centre for Diagnostics in Zoonotic and Emerging Infectious Diseases, the only academic center, and one of two in the US (the other is CDC), that participates in outbreak investigation for the WHO.
      In 1989, Lipkin was the first to identify a microbe (Bornavirus) using purely molecular tools[1]. Lipkin was employed by University of California from 1990-2001. He began as Assistant Professor in the departments of Neurology, Anatomy and Neurobiology, and Microbiology and Molecular Genetics. He advanced to full professor in under six years and was named as the first Louise Turner Arnold Chair of Neuroscience before moving to Columbia University.

      In 1999, Lipkin led the team that identified the West Nile virus in brains of encephalitis victims in New York State [2].
      In April 2003, he sequenced a portion of the SARS virus directly from lung tissue, established a sensitive assay for infection, and hand carried 10,000 test kits to Beijing at the height of the outbreak. As the first foreign consultant to gain the confidence of the Ministry of Science and Technology and the Chinese Academy of Science he was named Special Advisor to China for Research and International Cooperation in the Fight Against SARS and was instrumental in promoting disclosure and outside collaborations in infectious disease research and public health management. His position recognizes this extraordinary service, wherein Lipkin and his colleague Thomas Briese, traveling to Beijing at the height of the SARS outbreak at the request of the Chinese government, hand-carried 10,000 test kits to be used for identification and containment of infected individuals, and coordinated the national research efforts with Chen Zhou, the current Minister of Health of China.

    • XMRV Workshop Videocast Tomorrow-
      the closing Q&A section – perhaps the illuminating part of the
      conference will be videocast live tommorrow at 5:15 EDT. Andrea Whittemore posted a note
      stating that “Things will finally be put to rest during Dr. Ruscetti’s talk on
      CFS”. 

      What an acknowledgement of Dr. Mikovits and the WPI’s
      work this Workshop is! Ten months ago no one was interested in XMRV. Ten months
      ago who would have dreamed the Director of the NIH would be opening an workshop
      focused partly on ME/CFS or
      that a Lasker Award winners or other luminaries would be
      researching ME/CFS.

    • We all want the answer NOW but it’s utterly astonishing what’s been
      accomplished in such a short time. Here’s to a Workshop that, as Dr. Collins put it, asks
      ‘penetrating questions’ and comes away with empowering answers that ultimately
      lead to a resolution of this disorder.

    Sept 6th

    • Head Honcho of NIH To Start Off XRMV Workshop – It was clear in the Science
      paper that XMRV was
      attracting a caliber of researchers we haven’t seen very often from; the
      Ruscetti’s and the Silverman’s of the research world just hadn’t been spending much time
      in the lab on ME/CFS.
      Prohealth’s announcement
      that the Director of the National Institutes of
      Health – the big honcho himself, Dr. Francis Collins, decided to bump what’s his
      name off the podium, and deliver the opening address for the XMRV Workshop
      himself, appears to have taken the ‘name game’ to a whole new level. Yes, it’s
      just an opening address and that in itself means little but he wasn’t on the
      ticket earlier and it’s not hard to think someone hasn’t been whispering in his ear
      “This is one you want to get on top of”. One wonders what he will be saying about ME/CFS
      and what other surprises the Workshop might have in store..
    • The XMRV Black Hole – The UK, at this point, appears to be a kind of black
      hole for positive information on XMRV; the positive stuff goes in and a negative
      interpretation gets quickly shot out. The UK Science Media center presented two
      short critiques of the findings that were, well, completely critical.
      Neither Dr. Weiss, nor Dr. McClure could say anything good about it and focused
      on the abscence of ‘blinding’, the four negative studies, etc. Dr. McClure was
      ‘mystified’ by the ability of both the Alter group and the WPI to find MLV’s
      after only the first pass of the PCR yet both Dr. Mikovits and Dr. Lo have
      pointed out that the different primers they used could have accounted for that.
      Almost all the parties, both pro-leaning and anti-leaning XMRV, agree that more
      study is necessary to nail down what has been causing the disparate results.
      With several positive studies reportedly about to get disseminated one wonders
      if that question will begin to be answered to most researchers satisfaction.
    • The XMRV Polls -as we await the results of XMRV Workshop let’s take a look
      at the XMRV Polls on Phoenix Rising. The Combined PCR/Culture poll was begun
      with expectations of high participation yet almost 10 months later only 33
      people had taken it. Of those 60% had tested positive to at least one of the
      tests. With 40 people presenting results on the Culture test
      55% percent tested negative. The Antibody Poll was started in April and five months later only 12
      people have taken it; 59% testing positive and 41% negative. Because the antibody test was likely taken
      by people testing negative to the other it could bump up the final percentage of positives significantly.
      The small polls suggest, though,
      that while many people are testing positive a chunk of people with ME/CFS are
      testing negative at this point. Severely ill people do not appear to be testing positive more often
      than moderately ill people. What the final, validated  XMRV test will
      show, of course, is unclear.

    Sept 4th

    • XMRV and Lyme Disease?
      - XMRV has been creeping into other disorders from almost the day the
      Science paper came out. Dr. Cheney recently stated in the intro to one of his
      ‘pay-for’ articles that in his patients Lyme does not appear to exist independently of XMRV -which suggests to him that they are
      interconnected in some way. Now Daffodil on the PR Forums reports that XMRV is on the agenda of a big Lyme conference in October. 

      The disorders XMRV is connected to will be an increasingly important factor as other questions get taken care of. Will
      it be associated with other pathogens? Does it ‘open’, so to speak, the door for them? Does it have a special
      connection with herpesviruses  in CFS or is it associated with other pathogens?
      Plus the all important question – where does XMRV stop?

      The first big step for XMRV, of course, though, is getting recognition from
      important opinion-makers in the research world, such as Dr. Alter, that XMRV is
      definitively associated with ME/CFS. Once that question is erased in the
      research community it can move on….With the
      cautious tone overall from the traditional research community, we’re definitely
      not there yet…(Where is Dr. Racaniello’s blog on the Alter report?)….

    • Dr. Deckoff-Jones Digs into the MLV
      research -
      check out her blog for lots of good, if technical, information on
      MLV’s. She notes that Dr. Sandra Ruscetti has been studying them for over 30
      years. (What a strike of luck that Dr. Mikovits just happened to be  deeply
      associated with the Ruscetti’s…How does that happen? Sometimes the gods do
      smile on CFS.) It’s not easy reading (she says, “Yes…It is harder than
      rocket-science” :) ) but there’s alot there.
    • XMRV Workshop – We know that positive studies are being ‘released’ at the
      Workshop. What we don’t know is how strong each of them is and what kind of
      difference they will make….Will the big-wigs be swayed by a study by physician
      Paul Cheney? Probably not. Might they by Rebecca Hansen?  Probably more so. Will
      they by Dr. DeMeirleir? Judging from their reception to his RNase L work -
      perhaps
      not. They’ll be most interested in very rigorous studies that dot all their i’s and
      T’s and it will help greatly if they come from major figures like Dr. Alter. The
      reception to the positive studies will be interesting. Will things begin to flip
      at the Workshop or just get better?
    • Webcast of Workshop Final Q & A: Here’s the panel for the final Q&A session.
      Thank god, Dr. Mikovits – who is basically responsible for the Workshop
      occurring at all -  is on the panel. (Could you imagine??) Thanks to Bob
      for providing this.
      It looks like a good panel for XMRV with an NCI figure,
      Dr. Coffin and Mikovits participating.
       

      The Q & A panel will consist of  the
      following experts in the field of XMRV:

      Jerry Holmberg, US Dept. of Health and Human Services,
      Washington,USA

      Judy Mikovits, Whittemore Peterson Institute, Reno, USA

      on the Phoenix Rising Forums had a very hard time with them and stopped them and
      continued to decline. (He has not been tested for XMRV but thought he surely had it given
      statements on prevalence he had heard. He did the antiretrovirals unsupervised and bought them online -
      definitely not a good idea to go this route!).

    available for viewing. Thanks for Filfa4 and Rrr for being alert and getting us
    this news.:)
    August 31th

    - It’s a two day workshop. It starts out with basic
    stuff; where the virus integrates itself into the cell’s genome, which types of
    mice may contain XMRV-like sequences, and then there is a presentation on a
    ‘novel gene product’ of XMRV – which means? what – a protein?? In any case it
    appears to be something new to science which is always interesting.

    In the next session there is a talk on animal
    ‘models’, which are animals researchers
    use to give XMRV to and then study. Animal models are critically important to understanding how
    pathogens function and its good to see researchers focusing on animal models so early.
    Dr Bishop will
    talk on ‘Host Restriction Factors’ which are factors in our cells that restrict
    viral replication. These factors may be one reason why XMRV appears to be different in prostate cancer
    tissues and the blood. Next comes a VERY INTERESTING lecture.

    Dr. Villinger  then talks on why XMRV Induces a Chronic Replicative Infection in Rhesus Macque Tissues and
    But Not in the Blood”.
    We’ve been wondering where, if any place, XMRV is replicating? We know it
    hardly happens in the blood but is there a tissue somewhere (besides the prostate) where it’s
    growing away? Dr. Villinger will tell us where in the bodies of these macaques XMRV has found
    a home. Is it the nervous system? (Wouldn’t THAT be exciting/appalling…) How
    about the lymph nodes? The blood vessels? These are macaques, not humans, but
    this presentation could have profound implications.

    The next talk by Dr. Kazak will fit in perfectly here because he will look at different
    variants in the XPRI receptor that XMRV uses to enter cells. These variants may determine which cells
    XMRV can get into and cannot. The next day starts out with the prostate cancer series which we will bypass, except to say
    that Dr. Singh is giving a lecture on pathogenesis. The section on CFS comes next.

    Dr. Mikovits and Dr. Ruscetti chair the section and he (not Dr. Mikovits) will lead off with a talk on subject he was hardly aware of until two years ago – chronic fatigue syndrome. Dr. Hanson
    is next. Thus far she has the only CFS/XMRV NIH grant that has been funded. It’s
    a full ROI grant which means (a) that she must have had some preliminary data
    and (b) that data must have been positive – so here we appear
    to have the third positive XMRV study to appear. We
    know she is studying Dr. Bell’s pediatric patients (or formerly ‘pediatric’ now
    middle-aged patients) and that her rather complex study wll look at a variety of immunological and other features.  One interesting question will be if she has
    blood samples from 25 years ago from these patients.

    Right next to her
    Dr. Huber will presumably report on her negative study – an
    interesting juxtaposition indeed. Dr. Lo will report on the Alter/Lo positive finding and then we believe we’ll have
    a second positive study report by none other than Dr. Mikovits herself.
    This appears to be the Invest in ME/WPI UK study that used an independent lab to
    replicate the WPI’s results. The title of this one is intriguing “the Detection
    of Infectious XMRV in the blood of ….in the UK”. One wonders if the inclusion
    of the word “infectious’ in there could mean anything special about this study?

    The Assay development section will start off by a lecture by a man who’s
    never been able to find any XMRV in patient’s blood – Dr. Switzer of the CDC. After the Alter/Lo
    study and the FDA’s statement that ‘sample preparation’ could’ve played a role in the inability of
    the CDC to find XMRV this lecture could be interesting. (Dr. Vernon’s test tube comments come to mind)… Could
    Dr. Switzer tell us
    something surprising here? aka ‘we made a mistake?’.

    Dr. Bagni will represent the WPI as she
    explains how to produce an antibody test for XMRV then we’ll get good news about the development of
    XMRV immunoassays  for large scale population studies. Finally Dr. Kearney
    - who may be part of the Blood Working Group will talk on his success in finding XMRV in blood products.
    (Things are definitely moving forward on the diagnostic front.)

    In the last session on Epidemiology the Bannert lecture will indicate to us that he did not find XMRV but he also shows that the bug can infect blood cells
    - which sounds that he’s replicated
    a key part of the Science paper (!) but still can’t find the virus…We’ll have another opportunity for
    another positive study when Dr. Blomberg talks about his search for XMRV in Sweden. Finally it appears that another
    member of the Blood Working Group will report multi-laboratory evaluations of different XMRV assays.

    Dr. De Meirleir is believed to have a poster providing the results of another postive study
    and the identification of an immmunological signature associated with XMRV infection. At this point
    it appears there may be at least three positive studies and possibly four.

    The 2-day Workshop indicates that
    Science is marching forward very quickly; indeed at lightspeed compared to what we are used to.  If XMRV wins out this could be just the beginning; the medical research establishment (contrary to our experience) in the US,
    after all, is vast
    indeed.
    Months ago, Dr. Klimas reported that retrovirologists were hungry for something new…Might
    ME/CFS go from doormat to hot research ticket? That would be something
    indeed.

  • The Silence that Deafens
    - how to explain what appears to be a near virtual media blackout on the Alter
    study in the UK? Several UK residents have reported looking fruitlessly for any
    mention of a paper that made it to several hundred other media outlets
    elsewhere. Somehow the story didn’t even make it onto the pages of the vaunted
    BBC. (How does this story make it to Iran, of all places, and NOT the UK?) One
    expects the Western media to display some independence but it seems that the
    British media, at this point, is only interested in one kind of story on ME/CFS
    and that story does not involve pathogens. Yes, they will cover a pathogen story
    if they can’t ignore it (and downplay it) but if they feel that they can ignore
    it, then it appears that they will. It’s amazing (and appalling) from the US
    side to see an entire country’s media en thrall to one belief system regarding
    CFS and it definitely messes with one’s idea of an informed and objective media.
    What a rough ride UK patients have…..

    As we watch the media in the US we can also see patterns forming. The Wall Street Journal has
    a journalist who appears to be very interested in CFS and she has made a difference there. The NYT does its
    generally thorough job and they’ve been giving XMRV and ME/CFS a real shot
    throughout. The Chicago Tribune, on the other hand,
    has focused on negative aspects. It appears that much matters on which journalist gets interested in the subject and what their
    own particular slant is.
    The message is- cultivate those reporters if you can.


  • NIH Goes Public on XMRV
    - The NIH finally threw its hat in the ring on the
    new XMRV findings. In the NIH Research Matters section the official NIH release
    starts off with a bang “New research supports the idea that viruses may play
    a role in chronic fatigue syndrome (CFS), a debilitating disease that affects
    millions of people nationwide” What a nice sentence that is; it fits in viruses,
    a
    debilitating disease and ‘millions of people’;
    they almost make it sound like we have a major problem here….Did Fauci
    groan when he saw this? Is he starting to wonder how he’s going to explain how
    under his direction the NIAID has basically ignored CFS and it’s millions of
    retroviral infected patients for decades? How he is going to explain his paltry
    budgets over the past 25 years for the millions of ill patients? One fervently
    hopes that at some point he’ll be pressed at some point to explain just that. The neglect of the ME/CFS community
    by the federal goverment borders on being criminal and hopefully the bureacrats in charge
    will be held to account for their apathy and negligence. (Can you see a 60
    minutes program lighting these people up? I can). 

    In any case the article illustrates that
    no matter what happens with XMRV, CFS should now be associated in many people’s
    minds as something that’s ‘debilitating’ and common. Overall its a nice little
    article.

  • August 28th

  • Whoops! NIAID Steps Forward - It’s true that the NIAID has been no friend to CFS…in fact none of the federal agencies could
    be characterized as ‘friends’ and I really blasted them in the last buzz post but
    that’s all the more reason acknowledge them when they do shake off their
    negative mindset and stepforward. I was informed that
    it was none other than the NIAID that helped fund Dr. Alter’s work. They definitely get two stars for that, and
    hopefully, over time, we will see much more.
  • Dreambirdie’s superb ME/CFS video is on CNN Ireport
    - please check it out,
    give it some hits and watch it spread.
  • Hot CFIDSLINK coming up.
    The next weeks CFIDSLink is reportedly going to feature
    Q&A’s with professionals (including Dr. Alter) about XRMV. One question
    we know Dr. Alter will be answering is if he found any MLV’s in the CDC’s
    samples. If he didn’t then either the CDC’s ‘CFS’ group is not just different
    but amazingly different from the Komaroff’s group of CFS patients in the Alter study OR the
    CDC has a problem with ‘sample preparation’. It was Dr. Vernon who pointed out
    that the CDC’s test tubes might not have been right for virus collection. When a
    virus is as rare as XMRV appears to be in the blood it might not take much to
    knock out what little is there. What is going on? Maybe by Workshop we’ll
    know….
  • The September 7-8 International XMRV Workshop is going to be a doozy!
    The
    CDC will be presenting their lecture on assays just after Dr. Alter’s assays
    found MLV’s….THAT will be interesting. Kate Bishop who basically cracked an
    essential part of the XMRV mystery for Dr. Mikovits will be there. THAT is
    encouraging. We believe that at least two positive XMRV studies will be reported
    there and Dr. DeMeirleir will report that he’s found distinct immune
    abnormalities in XMRV infected patients. THAT will be outstanding.  Other
    researchers will, no doubt, be deep in discussion about MLV’s and XMRV and how
    to piece together all these different. THAT will be intriguing. Dr. Singh, from
    what I’ve been told, from someone would know, may have the best XMRV studying
    going and she’s talking as well….and at the OFFER Conference on Sept 11th in
    Salt Lake City. THAT will be illuminating. 

    This is the hot ticket in
    town! The Workshop filled up quickly and is no longer open but congratulations
    to those CFS patients who managed to get in (And boo-hoo for us (me!) who
    didn’t)….We look forward to your reports!

  • Medscape News Praises Alter
    Study
    - while being careful to cite issues that need to be cleared up
    Medscape News turned in a very positive assessment not only of the Alter study
    but the impact of the study on the field. We learned that the Alter group tested
    some of the CDC’s samples but that they weren’t able to provide samples to the
    CDC themselves because they didn’t have enough material. 

    Dr. Alter suggested that the different retroviruses the WPI and his group picked up
    may be due to geographic differences in prevalence and patient selection.
    “Dr. Alter said the most likely reason for the discrepancy in results is patient selection. Diagnosis of CFS is based on a symptom complex, not a specific disease marker.
    All patients in the NIH-FDA study met the accepted diagnostic criteria for the syndrome, and most blood samples
    were from the patient population of a single coauthor, who is a CFS expert, he said.

    There may be a geographic difference,” Dr. Alter told Medscape Medical News.
    “In the Northeast, CFS may be due to MLV, and in the West, it may be due to XMRV
    .”
    which is an interesting idea but doesn’t seem likely, at least from this
    laymen’s perspective, to hold.

    It’s true that the WPI patients came from
    doctors across the country, none of which to my knowledge, was in the
    Northeast. The WPI, however, has found XMRV variants in those patients dating back to the original paper. While those variants were not in the
    original paper they were used as supporting material for the Science editors who
    wanted confirmation that the WPI was not looking at a contaminant. The bottom
    line is that the WPI has apparently known of XMRV variants from the beginning.

  • Canadians – Your XMRV study awaits you! - the CAA reported that Dr.
    Eleanor Stein at the University of Alberta is starting an XMRV study for people

  • Science Article Charts Shift in Thinking – an article in the presitigous Science journal looked at the
    Alter paper and found alot that it liked. Stating that “Even skeptics are impressed
    by how much care the authors of the new study took to ensure accuracy” it was
    clearly a very solid piece of work – even Dr. Monroe of the CDC agreed to that “The data do seem solid”, admits Steve Monroe, director of CDC’s Division of High-Consequence
    Pathogens and Pathology.” And he wasn’t the only one “It’s simply a good paper,” adds virologist
    Reinhard Kurth, former director of the Robert Koch Institute in Berlin.
    Alter, a widely respected virologist and winner of the Albert Lasker Award for Clinical Medical Research,
    “clearly knows what he is doing.” 

    Questions lingered about reconciling the ‘new’ retroviruses found and the inability to find XMRV, and the disparate results of the other studies, and clearly more work needs to
    be done to get the scientific community as a whole gets on board but one had the
    feeling, barring some untoward surprise, that that was a matter of time. With regard to those ‘new’ retroviruses, Dr. Mikovits
    reported that the WPI, over time, has found new variants. (In fact, Dr. Mikovits told me they are present in the WPI’s patent
    application.)

    When will the research community get on board – one way or the other? We finally got
    what appeared to be a solid date: “By
    Christmas”, Dr. Kurth reported – by Christmas they will have come to a consensus.

  • National Cancer Institutue (NCI) Producing XMRV ‘Toolkit’
    - BeesKnees on the
    Forums reported that the the National Cancer Institute and Science Applications
    International Corporation (SAIC) are creating an XMRV Toolkit to help study the
    virus. We heard that the NCI had spent over a million dollars on basic XMRV
    research and this may be the fruits of their labor. This toolkit, which consists
    of ‘expression plasmids’ for all the proteins in XMR, will assist researchers in
    many ways;  developing antibody test, as a diagnostic tools, developing
    vaccines and immunotherapy. It should accelerate research
    greatly…..“The development of these
    XMRV tools is expected to save researchers months in laboratory
    production time and thousands of dollars in labor costs.”
     

    The development of this tool demonstrates the leadership role the NCI
    has played in XMRV. It also starkly illustrates how hands off the big retroviral institute at the NIH, the National Institute of Allergy and
    Infectious Diseases (NIAID) has been. Patients and some researchers have been critical of the CDC’s XMRV study but we should all
    take note of the fact that if it was up to the NIAID, there might be no research at all
    on XMRV. At least the CDC
    has devoted some time and money to this issue. The NIAID backed away from ME/CFS
    long ago and it continues to treat it as it would a pariah disorder. One might
    ask who the bigger ogre is in this scenario.

  • FDA FAQ’s on XMRV
    - The FAQ’s suggest that both the CDC and Dr. Alter are testing each others
    samples. Dr. Alter did not find XMRV in the CDC samples either but what about
    those MLV? And what had the CDC found in Dr. Alter’s samples? All questions we
    hope will be answered in that increasingly exciting Sept workshop.
  • Terrible Timing! CDC CFS Job Now Open!
    - It took them, what? At least
    six months, but the CDC has finally put the job posting for the CFS job out but
    the timing or this is terrible and it suggests that either they’ve decided about
    the role XMRV plays in CFS or they just don’t care. With scientific consensus on
    this all important pathogen just a few months away why not wait and be sure to
    attract the right kind of individual for the job? The posting opened Aug 19th
    and closes two weeks after that.

    • Four Viruses? The Alter Paper Arrives: A Review – I just posted a long review of this
      complex and fascinating paper, and what, so far as I can figure out, it means.

    • DeMeirleir Reports RedLabs and Researchers Confirm WPI Findings
      - Dr.
      DeMeirleir reported XMRV was alive and well in European ME/CFS patients. Unless
      they are using a different technology than that licensed to them by VIP Dx this
      was welcome but not startling news, as few expected the virus not to be found in
      Europle. The most intriguing part of Dr. DeMeirleir’s accouncement was that he
      had identified an immune signature similar to that found in ‘symptomatic’ HIV
      patients. There was no telling why that signature had not popped out before in
      ME/CFS but it could be that it is showing up now because of the  more
      selective cohort (ie XMRV positive patients). Dr. De Meirleir sounded very
      hopefull stating “It seems that for the roughly 17 million CFS / ME patients
      world-wide end to a long ordeal surrounding the recognition of their illness.
      The development of targeted therapies is already underway, both in Belgium and
      abroad” He will report his finding at the Sept 7/8 workshop.

    • Kitei Paper on Alter Story - doing her due diligence Mindy Kitei at CFS
      Central not only got a hold of the paper before publication but also interview
      Dr. Alter, Dr. Komaroff and others. (You
      can now find the paper here
      .
      Check out a commentary on the findings here

      The surprise of the paper was what Dr. Alter didn’t find – “XMRV”! Even more surprising was the fact that
      his finding of a melange of closely related viruses actually made sense in some ways. One reason that none of the six or so
      CFS studies have been able to find ‘XMRV’ may be that the type of XMRV they looked for was different.
      As Dr. Mikovits reported in
      “A Different Kind of XMRV” the reference type for XMRV testing was
      derived, naturally, from the sample they had on hand which were from prostate
      cancer patients. Several studies since the publication of the Science paper have
      indicated, however,  that the makeup of XMRV in prostate cancer tissues
      very likely differs from that found in the blood cells. That appeared to be due
      to the APOBEC3 enzyme present in blood cells which swapped out amino acids in
      the RNA of the virus.
      Dr. Mikovits talks about this is a
      video posted shortly after the finding,
      where she states that it appears that ‘a family of murine retroviruses appear to
      have infected people with ME/CFS.

      It’s still a mystery, at least to me, however, how the WPI
      found XMRV at all since they presumably started searching for it in the blood last year using
      the material they had on hand -which were reference samples from the prostate. It may be
      that faulty methodology indeed, still does play a role in the inability of other
      groups to find this virus.

      Kitei rKitei reported
      that Dr. Alter believes his
      findings confirm the original XMRV findings stating “Viruses tend not to be homogenous,� Alter explained to CFS Central
      in a telephone interview. �The fact that we didn�t find XMRV doesn�t bother me because we already knew that retroviruses
      tend to be variable. They mutate a lot, basically. This is true of HIV and HCV [hepatitis C virus]. It�s not one virus. It�s a family of viruses.�
      Dr. Alter should certainly know – his work on hepatitis viruses that lead to the discovery of two new
      viruses garnered him the ‘Nobel Prize’ of Medicine – the Lasker Award.

      Dr. Alter found no less than four different types of heretofore undiscovered mLV’s in CFS. They were named, appropriately,
      “CFS Type I”, “CFS Type II”, etc.

      Mutating over time like any good virus should – Dr. Alter was also able to find the pathogens in blood that was fifteen years old
      and then retest those individuals today. He found the virus present in 7/8 of them in mutated form – which is exactly what one would
      expect from a virus over tiem.

      According to Kitei, Dr. Alter felt the delay in releasing the study
      only strengthened the study, stating �There were no changes in the conclusions,
      but we added data that made the conclusions stronger,� he explained. �For one
      thing, we did some further work to feel confidant that there was no
      contamination�. We had hundreds of negative controls, and every assay had
      negative controls. And then we used an assay from mouse mitochondrial DNA and
      found that there was no evidence of mouse contamination. We had variation in the
      viruses we were finding. If there was a contaminant, you�d find one species, not
      several.�

      Now Dr. Alter will give XMRV its next big test – he will search for it in a wide variety of
      disorders. The danger is that it is widespread in chronic diseases, which, would negate its importance
      unless it really is some sort of superbug. Hopefully, it will be found clustered in a series of
      ‘NEID’s’ such as FM, GWS, MCS, IBS. Now we await the results of the briefing.

    • VIP Dx Announces New Tests - In a nice bit of timing
      VIP Dx announced a new antibody test for
      XMRV and its related variants. The related variants item – the fact that
      more types of human murine related retroviruses are present in ME/CFS- is the
      second bit of big news we expect the Alter paper to bring. This finding – that a
      variety of heretofore undetected ‘mouse’ retroviruses, all closely related to
      XMRV have infected the human population could, one would imagine, unleash an
      enormous amount of interest in the scientific community and possibly pave the
      way for insights into a number of different diseases and/or explain the
      different subsets in CFS. (If 80% of CFS patients test positive for XMRV then
      something will need to explain the subsets within that
      subset
      ). The case with HIV is possibly quite instructive as different
      types of HIV result in dramatically difference illness courses with the
      mortality rate for one form significantly lower than the other.

      correct the blockbuster paper will come out on Tues. Only time will tell; if it

    • XMRV in Press – papers
      on XMRV continue to pour out. The latest, a 50 plus page tome, described
      successful efforts to detect antibodies in XMRV infected primates. Interestingly
      they reported XMRV illicits a ‘much less robust’ antibody than HIV. Initial
      antibody levels are high and then decline quickly to basal levels (?) after
      about 4 months. They believe this is probably due to reduced replication levels
      as the body gets the infection under control although they did note another
      study indicated the virus was present in many organs (even if it’s not
      replicating). A similar antibody response occurs in  HTLV infected primates
      and it may not reflect what happens in  humans.

    • HGRV Debuts
      - A name change already? Now that is something people with
      ME/CFS/CFIDS/ME/CFS/EBV Syndrome are familiar with. Things are moving fast at
      the WPI. Feeling confident that issues about the XMRV’s existence have been
      settled they are building a foundation for the future, part of which involves calling this
      pathogen by an appropriate name. As Dr. Burrascano pointed out XMRV is a human
      not a mouse (ditch the M), you can’t say its an exogenous virus because
      it’s a uniquely human virus (scratch the x); what it is is a human infectious gamma
      retrovirus – the first one we know of; ie its an
      HGRV…..the pronunciation of which is up to you. (These are biologists not poets). From an aesthetic standpoint it only
      gets worse…the disorders associated with HGRV are HGRADS (Human gamma retrovirus associated disease).
      So, congratulations – if you tested postive for XMRV you may have an HGRAD. 

      The tongue twisting names are not, unsurprisingly, going over well at the Forums. One person suggested it sounded like a
      rocket launcher from the Soviet Union.
      Some Forum members
      have jumped in with their proposals. Human Associated Gamma Retrovirus Disease or HAGRID gets the
      Harry Pottery character into the picture while being more picturesqe – I feel Hagrid – (haggard), HGIV, HGRV,
      HGR……..

      That the new names will be proposed
      in a just a few weeks at the XMRV Workshop on Sept 7th – demonstrates again how
      confident the group is and suggests they may believe enough positive information
      will be coming out over the next couple of weeks to sway the group. What a turnaround this is from a couple
      of weeks ago when the CDC, having locked up the Assay presentation at the workshop, appeared to be in drivers seat with XMRV.

      Hold onto your seats, Dr. Burrascano, a member of the Symposium stated “the volume of new and important information about this virus and its disease associations is increasing rapidly”.


    • The Lo-CFS Connection
      - Dr. Alter appeared out of the blue; a major
      researcher without any apparent connections to ME/CFS he appears to have stepped
      in at just the right time to, kind of, save the day. But is he really out of the
      blue? A thread on the Phoenix Rising Forums indicates  that his partner,
      Dr. Lo, played a major role in mycoplasma research and actually authored a paper
      on CFS and mycoplasma. His record suggests that he’s very good at finding
      difficult to find bugs. He did not find an association between mycoplasma’s and
      CFS but it may be that he thought at some point a bug was going to show up.

    • Dr. Mikovits
      Breaks the News on the FDA Paper
      -Several weeks prior to publication Dr. Mikovits spilled the beans on the
      FDA XMRV paper,
      stating in an interview with RGJ.Com, what has seemed to
      be more and more obvious – that the Alter paper is going to confirm the WPI’s
      findings when it is released. While no one yet had directly said so, the news
      seemed to be in the air. In an interview in Nevada Newsmaker Annette Whittemore
      very confidently said several new replication studies will shortly out confirm
      the WPI’s findings and the mood overall seemed very good. 

      It’s a big day, a huge day for CFS and, of
      course the WPI. How fitting that the WPI, which has endured six months of
      skepticism
      as study after study has
      failed to find XMRV not only in ME/CFS but in other diseases, was greeted with
      this news as they cut the ribbons on their new facility. While much work remains
      to be done the news that the several positive studies are on the way potentially
      means a new dawn for ME/CFS.
      The
      implications of the finding are truly immense – legitimacy, vastly increased
      funding, new treatment possibilities and an immense, immense weight taken off
      ME/CFS patients shoulders.There was already good news on the treatment front from Andrea Whittemore, who
      had became dangerously ill after having to go off Ampligen, as
      she
      reported on Nevada Newsmakers
      that she had improved significantly on new
      treatments linked to XMRV. With the confirmation of XMRV in CFS the drug
      companies appear to be picking up track right where they left off six months ago
      when the negative studies appeared. Dr. Lombardi stated that treatment trials
      could begin at the WPI soon.
      Representatives of drug companies and diagnostic laboratories are reportedly
      among those attending the WPI’s Symposium this week.

      Annette reported that the the WPI is
      putting together a team of physicians to lead the medical end of the WPI as fast
      they can and hope to open in medical side of the facility in late Fall.Dr. Mikovits also scooped herself on a paper she expected to published at the
      end of this year that she reported will demonstrate distinct immune
      abnormalities are present in ME/CFS patients infected with XMRV. This is a major
      accomplishment because it suggests an XMRV infection could have profound effects
      on the immune system indicating it is more than a ‘passenger virus’. With
      researchers able to show XMRV is causing distinct immune abnormalities the next
      step is to show that drugs that remove the virus and recorrect the immune system
      abnormalities lead to improved health. Three drugs have been able to stop XMRV
      in the lab and Dr. Lombardi felt many more were potential candidates stating
      there was alot of ‘low-hanging fruit’ available on drug company shelves.
