Fibromyalgia, chronic fatigue syndrome, and myofascial pain syndrome.
Fibromyalgia was almost completely absent from an urban affluent population compared with poor urban and rural communities. Seventeen percent of Gulf War veterans with soft tissue syndromes had fibromyalgia, a much higher rate than was seen in previous studies of rheumatic disease in the military population. A state of central hyperexcitability in the nociceptive system was reported in fibromyalgia. Altered functioning of the stress-response system has been further documented in fibromyalgia and chronic fatigue syndrome. Administration of growth hormone to patients with fibromyalgia who have low levels of insulin-like growth factor 1 resulted in improvement in their symptoms and tenderness. An association between chronic fatigue syndrome and initial infections was demonstrated. A correlation between particular immunologic abnormalities and measures of disease severity was documented in chronic fatigue syndrome. Concomitant fibromyalgia in other rheumatic diseases was a major contributor to poor quality of life. A favorable outcome of fibromyalgia in children was reported; the majority of patients improved over 2 to 3 years of follow-up. Treatment of patients with fibromyalgia continues to be of limited success.
