title: Severe thrombocytopenia in Epstein-Barr virus-induced mononucleosis.
abstract: Severe thrombocytopenia is a rare complication of Epstein-Barr virus-induced infectious mononucleosis. We evaluated the clinical and laboratory data from seven patients seen between 1976 and 1985 whose lowest platelet counts varied from 3 to 25 x 10(9) per liter. Five of the seven patients were initially thought to have either acute leukemia or idiopathic thrombocytopenic purpura; eventually, however, primary Epstein-Barr virus infections were confirmed in all patients. Two of six patients tested had antiplatelet antibodies during the acute phase of their illnesses. Eight additional patients with acute disease who had only mild thrombocytopenia (94 to 144 x 10(9) per liter) were also tested for platelet antibodies with negative results. Steroid therapy was administered to three patients and platelet transfusions to one. All seven patients recovered with no serious hemorrhagic sequelae.
