[Nmefman] ANNOUNCEMENT: CDC REPORTS NEGATIVE RESULTS ON ITS XMRV STUDY FOR CFS

Dear Friends: Please find below a short report on the U.S. Centers for Disease Control and Prevention (CDC) study on XMRV and CFS. As you know, this is contary to the October 2009 publication in Science that suggested a possible link between XMRV and CFS. It is also contrary to the Whittemore Peterson Institute's research study and the NIH and FDA report which is not published. You will note that the definition used was the 1994 International Definition which stresses the fatigue factor. Lydia ABSENCE OF EVIDENCE OF XMRV IN CFS AND HEALTHY CONTROLS IN U.S. POPULATION On July 1, 2010 the U.S. Centers for Disease Control and Prevention (CDC) reported results from researchers and colleagues of two institutions in which they found no evidence of infection with xenotropic murine leukemia virus-related virus (XMRV) among patients with chronic fatigue syndrome (CFS) and healthy controls in the United States. The CDC-led team tested archived blood specimens from CFS patients and healthy controls. The blinded testing was performed at CDC and two other laboratories with negative results. The CDC concluded that these data do not support an association between XMRV and CFS in their study population. Their report was published in an open-access journal Retrovirology 2010, 7:57 (July 1, 2010) By William Switzer, Hongwei Jia, Oliver Hon, et al. See http://www.retrovirology.com/content/7/1/57 for summary. It can be seen in its entirety on Provisional at http://www.retrovirology.com/content/pdf/1742-46907-57.pdf To evaluate a possible association with XMRV with CFS, the CDC tested blood specimens from 51 persons with CFS and 56 healthy persons and were from previous study groups of people who had taken part in population-based studies of CFS in Wichita, Kansas and in Georgia. Patients in Georgia had been referred by physicians to a registry of fatiguing illness and had met the criteria of the 1994 International CFS Research Case Definition. Lydia E.
