The Massachusetts CFIDS/ME & FM Association, a 501(c)3 founded in 1985, exists to meet the needs of patients with CFIDS (Chronic Fatigue and Immune Dysfunction Syndrome, also known as Chronic Fatigue Syndrome), ME (Myalgic Encephalomyelitis) or FM (Fibromyalgia), their families and loved ones. The Massachusetts CFIDS/ME & FM Association works to educate health-care providers and the general public regarding these severely-disabling physical illnesses. We also support patients and their families and advocate for more effective treatment and research.

The recent multi-center study published on September 18, 2012 in mBio® (the online open-access journal of the American Society for Microbiology) concludes that no evidence of XMRV (xenotropic murine leukemia virus-related virus) and pMLV (polytropic murine leukemia virus) was found in patients with Chronic Fatigue Syndrome, disproving previous findings and hypothesis.

W. Ian Lipkin of Columbia University, a co-author on the study, reported "The bottom line is we found no evidence of infection with XMRV and pMLV. These results refute any correlation between these agents and disease." (Source: Neuroscience News, September 18, 2012).

Notice about names

The Massachusetts CFIDS/ME & FM Association would like to clarify the use of the various acronyms for Chronic Fatigue Syndrome (CFS), Chronic Fatigue & Immune Dysfunction Syndrome (CFIDS) and  Myalgic Encephalomyelitis (ME) on this site. When we generate our own articles on the illness, we will refer to it as ME/CFS, the term now generally used in the United States. When we are reporting on someone else’s report, we will use the term they use. The National Institutes of Health (NIH) are currently using ME/CFS. The Centers for Disease Control and Prevention (CDC) are calling the illness CFS.

Until there is consensus on a name for the illness, the Massachusetts CFIDS/ME & FM Association name will not change.
