Eosinophilia-Myalgia Syndrome (EMS) is a chronic scleroderma-like illness that was caused by contaminated batches of L-tryptophan in the late 1980's. L-tryptophan is an over-the-counter dietary supplement. Symptoms of EMS are intense muscle pain, weakness, and burning skin rashes. Skin biopsies show scleroderma-like changes, and blood work reveals elevated eosinophils. Several thousand people were sickened before the illness and its cause were identified.
Eosinophilia-Myalgia Syndrome. In October 1989, the health department in New Mexico was notified of 3 patients with an unexplained acute illness characterized by intense myalgias and peripheral blood eosinophilia. Within weeks, a nationwide outbreak of this disease occurred. The disorder was termed eosinophilia-myalgia syndrome (EMS). Medscape.
Eosinophilia-Myalgia Syndrome Clinical Presentation. No specific etiologic agent has been found for EMS, although most individuals identified as having EMS during the acute outbreak consumed L-tryptophan (97%) prior to the development of the syndrome. Medscape, 01/30/2014.
