I think CFS being legitimately compared to AIDS would be the best thing to ever happen to us, both in terms of research and PR
true. plus atypical MS, autism, cancers will have it...
everything just seems to upsetting....no cure....ARV's being so toxic...reading about all the deaths..... all the tissue damage from years of the disease...only to be topped off by researchers still debating contamination!
its like there is never any good news for us
Judy Mikivits talk at UCLA 10/8/10
Here are some of the highlights of the talk as I understood them. This is not entirely comprehensive, just as much as I can recount from what I was able to jot down. I dont promise 100% accuracy and have put a question mark (?) wherever Im unsure:
Background
evidence of XMRV infection found in ~2/3 of CFS patients tested via PCR
infectious XMRV virus is detected in blood plasma of 90% of XMRV-positive patients
- more so than in the cellular portion of blood (PBMCs)
many CFS patients have disregulated expression of RNase L, an enzyme important for degrading the genetic material of viruses
many CFS patients have a low NK cell count (NK cells play a role in eliminating virus-infected cells as well as tumor cells)
XMRV (Xenotropic Murine Leukemia Virus-related Virus)
originated in rodents though apparently doesnt cause disease in rodents (?)
mode of transmission from rodents to humans is unknown, as is human to human transmission
- XMRV virus has been detected in saliva of infected patients (?)
a type of enveloped gammaretrovirus with only 4 genes: gag, pol, pro & env
env gene very similar to the homologous gene in murine (mouse) leukemia viruses (MLVs), gag gene has a deleted region relative to MLVs (loss of glycosylation site)
- genes of MLVs are activated in response to androgens and estrogens
Pathogenesis of MLV (?) infection in mice/rats
incidence of leukemia, lymphoma, MAIDS (murine equivalent of AIDS)
neurodegeneration, likely due to inflammatory processes
- virus replicates in brain capillary endothelial cells
- activation of neuroglial cells results in pro-inflammatory signals (cytokines)
- leads to leaky capillaries in the region of inflammation and neural damage
- CFS patient cytokine profile is very similar to what is seen in these rodents
Retesting of XMRV-negative patients from UK study
original study used PCR to detect XMRV gag gene (?)
retesting involved 1) PCR of env gene, 2) antibodies to detect env protein and 3) cell culture to detect infectious virus, all from blood plasma (?)
- 24/50 (48%) negative patients tested positive by this method (only 4% of controls)
- 80% of the positive retested patients had detectable XMRV env protein in plasma
- >80% of positive retested patients had endogenous XMRV-specific antibodies
- Dr. Mikovits emphasized the importance of testing via all 3 methods (which is done at
WPI for $350) from plasma, and to test for the env gene/protein
This was the best I could do, so I hope you find it informative. All the best,
Retesting of “XMRV-negative” patients from UK study
? How did they get to re-test these patients? I'd be surprised if Wessely would co-operate. Some confusion in the note taking maybe?
Has your friend got CFS? If not, it was very kind of them to take some notes for us. Thanks for passing them along.
What has Wessely to do with WPI retesting their samples?
from yahoo group:
"Dr. Mikovits XMRV Lecture Summary at UCLA
She's been addressing the problem of other labs/people not being
able to find the XMRV by teaching them on how to do it. She is breaking
up the disease into 2 parts. 1) the virus 2) the individual's DNA. She
is not sure if this is the only virus in CFS patients, when in fact she
has seen people with 2 and 3 virus's. She has identified 6 types of
defects in a persons DNA that makes them susceptible to the disease and
other diseases. She believes that a combination of AIDS drugs can
potentially cure a CFS patient. When asked about what type of doctor
should administer the AIDS drugs, she responded; an AIDS doctor. I
guess that there can be severe consequences, including liver failure.
Which is probably why she was presenting to AIDS doctors. She also
asked that they (UCLA) seriously consider clinical trials.
I felt that the UCLA doctors were receptive. There were several
questions and comments that were neutral to positive."
It may be unpopular with PWA, but I would hope we can instead find a lot of common ground; the views of physicians and researchers who deal with both groups might help...like this one:
"I have treated more than 2,000 AIDS and CFS patients in my career. And the CFS patients are MORE sick and MORE disabled every single day than my AIDS patients are, except for the last two months of life!"
– Dr. Marc Loveless
(infectious disease specialist and head of the CFS and AIDS Clinic at Oregon Health Sciences University, in Congressional Testimony, CFS Awareness Day, May 12, 1995)
