Intravenous Gammaglobulin, Thrombocytopenia, and the Acquired Immunodeficiency Syndrome

Abstract
To the editor: Recently, Mintzer and coworkers (1) reported the cases of three patients with immune thrombocytopenia, Kaposi's sarcoma, and the acquired immunodeficiency syndrome. Two of these patients were treated with high-dose intravenous gammaglobulin without benefit. We report the cases of two patients with thrombocytopenia associated with the syndrome who had a dramatic increase in platelet counts after such treatment. Patient 1: A 29-year-old white homosexual man had had thrombocytopenia (platelet count, < 30 X 109/L) for more than a year. His platelet-associated IgG level was significantly elevated, the lymphocyte T4/T8 ratio was low (0.40), and a serologic test for
