This is mind-blowing and thought it deserved it's own thread. A must read.

Politics?
(This part is really disturbing to me. I like to believe that people are generally good and do what they believe to be right. I know that's not always the case.)

Here are some of the biggest points.
UK XMRV Study
- WPI started a study in March 2010 to look for HMRV (Human MLV Related Viruses - both X and P) in UK ME/CFS patients.
- The study included 50 patients with ME who met the Canadian Consensus Critera, 50% male and 50% female, along with 50 controls. It was a blind study.
- The 100 samples were tested blindly by two labs who had never worked with MRV or mice (to ensure there was no possibility of contamination).
- The labs first tested plasma and 48% of the ME plasma samples were positive for XMRV (all were also tested for mouse DNA and were negative). Other samples were detectable only after culturing (some sort of special sample preparation). In some samples, only the virus was detectable; on others, only the antibodies were detectable. Multiple testing methods were necessary in order to find all of the XMRV positive samples.
- In all, 80%of the ME patients in the study were positive for XMRV.
- 4% of the controls were also positive for XMRV (in line with the original WPI study).
- Dr. Mikovitz emphasized that the XMRV was very difficult to find. They have learned that subtle differences in storage, handling, and testing make a big difference and that multiple methods must be used to find it all.
XMRV Family Studies
(This is the part of the day that totally blew my mind)
- In January 2010, WPI did a study using samples from Dr. Cheney's clinic in Dallas. They tested not only CFS patients but also their families, including children, parents, and siblings.
- 81% of the Cheney CFS patient samples were positive for XMRV.
- Ready for this? 50% of all family members of CFS patients were also positive for XMRV, whether they had any symptoms or not.
- They constructed family trees for each family. In addition to people with CFS, they also looked for family members with cancer and autism.
- They found XMRV positive: parents with CFS kids; kids with a CFS parent; kids with autism.
- In all, 54% of the parents tested were XMRV positive, 59% of the children tested were XMRV positive, and 82% of the kids with autism were XMRV positive. They detected additional XMRV positive people in 16 of 17 families tested who had 1 member with CFS.
- Detection of XMRV in these samples required multiple testing methods to find it all.
- They have no idea how XMRV might be transmitted between family members.
- By the way, the possible link between CFS and autism is not new. Other researchers have suggested it in the past because they see similar immune system dysfunction in kids with autism.
Politics?
(This part is really disturbing to me. I like to believe that people are generally good and do what they believe to be right. I know that's not always the case.)
- Are you wondering why we haven't heard about the amazing studies conducted by WPI in the UK and with families from Dr. Cheney's clinic? Dr. Mikovitz says no one will publish them. She said they keep submitting papers to various publications and they keep getting turned down.
- Dr. Mikovtz said what's happening with XMRV and CFS reminds her very much of the early days of HIV research. She said that just like back then, she has a drawer full of scientific studies no one will publish, but she will just keep on conducting studies and putting them in the drawer until things change.
- 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.
- Other speakers also mentioned that politics are involved. 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.
- Dr. Mikovitz says that the evidence of XMRV in CFS is actually stronger than the evidence of XMRV in prostrate cancer because of the more extensive testing methods used to date.
- Rumor is that the National Cancer Institute (NCI) has been told by someone high up in the government to pursue whether XMRV is involved in prostrate cancer but should distance themselves from CFS. Though I hate to believe something like this could actually happen, the speaker from NCI at CFSAC last week was the one who suggested that contamination might be responsible for the positive XMRV results in CFS. Dr. Mikovitz said that person was on the original team that found XMRv and has seen all of the data proving contamination is impossible.
