An important medical milestone for anyone connected with ME/CFS! Myalgic Encephalomyelitis / Chronic Fatigue Syndrome: Clinical Working Case Definition, Diagnostic and Treatment Protocols includes a clinical definition (clinical diagnostic criteria) for myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). The clinical case definition was developed by an expert medical consensus panel of treating physicians, teaching faculty and world leaders in the research of ME/CFS. An expert subcommittee of Health Canada established the Terms of Reference for the consensus panel. The definition more adequately reflects the complexity of symptoms of a given patient’s pathogenesis and should establish ME/CFS as a distinct medical entity and help distinguish it from overlapping medical conditions in the absence of a definitive laboratory test. “The clinical definition will enable clinicians to make an early diagnosis which may assist in lessening the impact of ME/CFS in some patients,” said Dr. Bruce M. Carruthers, lead author of the definition. “It will reduce the expensive problem of patients being sent to many specialists before being diagnosed and will allow patients to receive appropriate treatments in a timely fashion.” The panel's clinical case definition determines that more of the prominent symptoms are compulsory and symptoms that share a common region of pathogenesis are grouped together for clarity. In addition to severe prolonged fatigue, the definition includes the hallmark symptoms of post-exertional malaise and/or fatigue, sleep dysfunction, pain, two or more of the given neurological/cognitive manifestations, and at least one of the given symptoms from two of the categories of autonomic, neuroendocrine, and immune manifestations. Diagnostic exclusions and common co-morbid entities are also given. The special issue of the Journal of Chronic Fatigue Syndrome also includes a discussion of prominent symptoms, clinical practice diagnostic and treatment guidelines based on the best available research evidence, and an overview of available research on ME/CFS. The expert panel of 11 physicians—who have diagnosed and/or treated more than 20,000 ME/CFS patients between them—has developed a clinical case definition that provides a flexible conceptual framework based on the characteristic patterns of symptom clusters, which reflect specific areas of pathogenesis. The expert subcommittee of Health Canada selected the expert consensus panel. Authors include: Dr. Bruce M.
