Chronic Fatigue Syndrome and Rituximab

IV rituximab has been used to treat chronic fatigue syndrome. A large, well-designed new study shows it doesn’t work. Chronic fatigue syndrome (CFS), also known as myalgic encephalomyelitis (ME or ME/CFS), is a poorly-understood condition characterized by profound fatigue and a constellation of other symptoms. The diagnostic criteria, cause, pathophysiology, and treatment have been embroiled

Treating Chronic Fatigue Syndrome with Cognitive Behavioral Therapy and Graded Exercise Therapy: How the PACE Trial Got It Wrong

The PACE trial found that cognitive behavioral therapy and graded exercise therapy were effective treatments for chronic fatigue syndrome and could produce recovery in 22% of patients. It seems they got it wrong. The PACE trial said graded exercise is an effective treatment for CFS. CFS patients disagree. Chronic fatigue syndrome (CFS), also known as

Followup: More Evidence against the XMRV Virus as a Cause of Chronic Fatigue Syndrome

A mouse leukemia retrovirus, xenotropic murine leukemia virus-related virus (XMRVretrovirus), has been under consideration as a possible cause of chronic fatigue syndrome (CFS, and also prostate cancer). In a study published in Science in October 2009, Lombardi et al. found XMRV in 67% of CFS patients and 3.7% of controls. Several subsequent studies in the

When I first heard that a retrovirus had been identified as a possible cause of chronic fatigue syndrome, I withheld judgment and awaited further developments. When I heard that two subsequent studies had failed to replicate the findings of the first, I assumed that the first had been a false alarm and would be disregarded.
