Hope for Chronic Fatigue sufferers; concern about the blood supply by Jack Johnson at Las Vegas City Life Blogs
Hope for Chronic Fatigue sufferers; concern about the blood supply by Jack Johnson at Las Vegas City Life Blogs
But this discovery also has implications for the blood supply. Hardly anything is known about XMRVs relationship to Chronic Fatigue Syndrome, cancer or anything else, but some experts raise concerns about the possibility of this as-yet-unscreened retrovirus being in blood banks.
-Local health agencies seem to be still getting up to speed on this. The medical director for all United Blood Services locations in Las Vegas wasnt aware of the month-old Science article. A Southern Nevada Health District spokesperson declined to speak on this speculative topic.

Dr. Michael P. Busch, Director of the Blood Systems Research Institute, the research arm of United Blood Services parent company, Blood Systems, says, Its not that were keeping anything secret, but theres no reason to alarm anyone. Blood Systems also serves as the central lab for the National Institutes of Health blood safety network.

Busch says that every year or so, a potentially blood-transferable virus is identified with preliminary data associating it with disease, but most of the time these things dont evolve to be a serious problem.

Still, the Science article has launched his organization into a collaborative effort with a number of government organizations, including the Centers for Disease Control, the National Institutes of Health, and the Food and Drug Administration, to establish the prevalence of XMRV in the blood donor population. That study will start with a Whittemore Peterson Institute collaboration in Reno, where 1,000 healthy donors blood will be screened by multiple labs. Busch estimates it will take up to six months to see how prevalent XMRV is in the blood supply, and another six months to fully develop and get FDA approval of a test for screening, if it is determined one is needed.
Hillary Johnson, author of Oslers Web, a groundbreaking book about Chronic Fatigue Syndrome, thinks this discovery will have ripples for years to come.

Were kinda in a shakedown period, where the government is frantically trying to get a test together, but its not going to happen overnight, she says. In the meantime, I think that they would prefer to do this work unobserved by the general public because they dont want people to get panicky. She adds, The discovery of XMRV is certainly as big a story as A.I.D.S, and if its not now, its going to be.
Despite the local United Blood Services medical director not being aware of this development, Blood Systems Research Institutes Busch counsels caution in a follow-up e-mail to CityBlog.

I appreciate that you are sensitive to unwarranted concern re the safety of the blood supply and the need to maintain an adequate number of donors to meet patient needs, he writes. That said I do think that persons with diagnosed CFS should probably refrain from donating until specific studies are conducted to establish whether XMRV is causally linked to CFS and the virus is present in healthy donors and transmitted by transfusions. These studies (will) evolve quickly over the next 3-12 months.
