FDA and NIH confirm ‘XMRV findings’
Original Press Release from the Netherlands
Gendringen (NL) – June 22, 2010. The FDA and the NIH have independently confirmed the XMRV findings as published in Science, October last. This confirmation was issued by Dr. Harvey Alter of the NIH during a closed workshop on blood transfusion held on May 26-27 in Zagreb. Two journalists from the Dutch magazine for health professionals, ORTHO, who have been working on XMRV stories for several months, were able to obtain a copy of the Alter lecture.
In the October 8, 2009 issue of Science Express, the Lombardi-Mikovits group at the Whittemore Peterson Institute (WPI), the Cleveland Clinic and the National Cancer Institute (NCI) reported that 67% of 101 chronic fatigue syndrome (CFS) patients tested positive for infection with xenotropic murine retrovirus (XMRV). Only 3.7% of 218 healthy subjects tested were positive for this gammaretrovirus. Since that time, a number of research groups have proved unable to independently confirm these findings.
On Friday last, the AABB released an Association Bulletin recommending that its member blood collectors actively discourage potential donors who have been diagnosed with CFS from donating blood or blood components. This interim measure was proposed by the AABB Interorganizational Task Force on XMRV. This Task Force includes representatives from several government agencies, including the Center for Disease Control and Prevention (CDC), the Food and Drug Administration (FDA) and the National Institutes of Health (NIH).
The fact that the measure was introduced suggests the presence of information not yet published. The ORTHO journalists were able to obtain a pdf document of the lecture given by Harvey Alter at the IPFA/PEI 17th Workshop on ‘Surveillance and screening of Blood Borne Pathogens’ in Zagreb. The International Plasma Fractionation Association (IPFA) represents the not-for-profit organizations around the world involved in plasma fractionation. The IPFA is based in Amsterdam, the Netherlands.
The highly-experienced Dr. Harvey Alter is Clinical Studies Chief at the Infectious Diseases and Immunogenetics Section of the Department of Transfusion Medicine at the NIH Clinical Center in Bethesda. “The data in the Lombardi, et al Science manuscript are extremely strong and likely true, despite the controversy”, was one comment on the XMRV findings reported by Alter in Zagreb. “Although blood transmission to humans has not been proved, it is probable. The association with CFS is very strong, but causality not proved. XMRV and related MLVs are in the donor supply with an early prevalence estimate of 3%‐7%. We (FDA & NIH) have independently confirmed the Lombardi group findings.”
