Exciting New Research for Chronic Fatigue- It’s Not All In Your Head
Posted by admin on Wednesday, October 14th, 2009
As if every Chronic Fatigue sufferer did not crave validation: The New York Times ran an article today stating a study published last week in the journal Science suggested that might be the case, reporting that many patients who had the syndrome were infected with a recently discovered virus. The new suspect is a xenotropic murine leukemia virus-related virus, or XMRV, which probably descended from a group of viruses that cause cancer in mice. How or when XMRV found its way into humans is unknown. But it has also been linked to cancer in people: it was first identified three years ago, in prostate cancer, and later detected in about one-quarter of biopsies from men with that disease (and in only 6 percent of benign biopsies). It is a retrovirus, from the same notorious family that causes AIDS and leukemia in people.
But the new study is not conclusive, and a great deal of work remains to be done to find out whether the new virus really does play a role. Just detecting it in patients does not prove it is what made them sick; people with the syndrome may have some other underlying problem that makes them susceptible to the virus, which could be just a passenger in their cells.
Even so, thousands of patients have already contacted scientists, asking to be tested, said Dr. Judy Mikovits, the first author of the study and the research director at the Whittemore Peterson Institute in Reno, a research center created by the parents of a woman who has the syndrome. Dr. Mikovits said she expected a test to become available “within weeks.”
Dr. Mikovits and researchers from the National Cancer Institute and the Cleveland Clinic reported in Science that 68 of 101 patients with chronic fatigue syndrome, or 67 percent, were infected with XMRV, compared with only 3.7 percent of 218 healthy control subjects. Further testing after the paper was written found the virus in nearly 98 percent of about 300 patients with the syndrome, Dr. Mikovits said.
