eosinophilia-myalgia syndrome
eosinophilia-myalgia syndrome a sometimes fatal syndrome of severe myalgia associated with marked peripheral eosinophilia, associated with the ingestion of oral preparations of l-tryptophan; long-term sequelae include scleroderma and progressive neuropathy.e·o·sin·o·phil·i·a-·my·al·gi·a syn·drome (EMS), a probable autoimmune disorder precipitated by contaminated l-tryptophan tablets; characterized by fatigue, low-grade fever, myalgias, muscle tenderness and cramps, weakness, paresthesias of the extremities, and skin indurations; marked eosinophilia is noted on peripheral blood studies, serum aldolase is increased, and biopsies of peripheral nerve, muscle, skin, and fascia show microangiopathy and inflammation in connective tissue. Synonym(s): E-M syndromee·o·sin·o·phil·i·a-my·al·gi·a syn·drome (ē'ō-sin-ō-fil'ē-ă mī-al'jē-ă sin'drōm) A probable autoimmune disorder precipitated by ingestion of contaminated l-tryptophan tablets, and characterized by fatigue, low-grade fever, myalgias, muscle tenderness and cramps, weakness, paresthesias of the extremities, and skin indurations; marked eosinophilia is noted on peripheral blood studies; serum aldolase is increased and biopsies of peripheral nerve, muscle, skin, and fascia show microangiopathy and inflammation in connective tissue. eosinophilia-myalgia syndrome A disorder featuring severe and persistent pain in the muscles, muscle weakness, loss of weight, fever, ‘pins and needles’ sensation (paraesthesia) and an exceptionally high level of EOSINOPHIL white cells in the blood.
