Among Singhs suggestions: Studies should have large numbers of patients, all of whom have been diagnosed according to well-recognized criteria for CFS. The number of healthy people used in studies as controls should also be large and come from the same geographic area as the patients. Blood samples from both patients and controls should be collected and treated the same way. Researchers shouldnt know whether the samples theyre studying are from CFS patients or healthy controls. And more than one kind of XMRV-detecting test should be used.
Singh adds that an ideal study would also use at least one test that has successfully detected XMRV in already published studies, perhaps also using the same patient samples.
Kim McCleary, the head of the CFIDS Association of America, a CFS advocacy group, says Singhs paper offers a really strong template for reducing some of the confounding issues in the studies that have already been published.
The guidance comes at an opportune moment. 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.
Singh tells the Health Blog: I sent a copy of my paper to Ian.
