British scientists have cast doubt on a new theory about the cause of Chronic Fatigue Syndrome (CFS).
A US study, published in the journal Science, indicated that a virus could trigger the condition, also known as myalgic encephalomyelitis (ME).
The recently discovered virus, xenotropic murine leukemia virus-related virus (XMRV), was linked to cases of Chronic Fatigue Syndrome (CFS) in the study
The study suggested that anti-retroviral drugs similar to those given to patients with the HIV virus could be use to treat CFS.
Several laboratories have since started offering treatment to CFS patients.
But a new study by British researchers shows no evidence of XMRV playing a role in the condition.
Professor Myra McClure, from Imperial College London, one of the authors of the British study, said: ”We are confident that our results show there is no link between XMRV and Chronic Fatigue Syndrome, at least in the UK. The US study had some dramatic results that implied people with the illness could be treated with anti-retrovirals.
”Our recommendation to people with Chronic Fatigue Syndrome would be not to change their treatment regime, because our results suggest that anti-retrovirals would not be an effective treatment for the condition.”
