Splenectomy for immune thrombocytopenia related to human immunodeficiency virus.

From 1 January 1984 to 31 August 1987, 11 patients underwent splenectomy for treatment of thrombocytopenia related to human immunodeficiency virus (HIV). Six of the patients had been previously treated with prednisone, five of whom showed some response. None of those who responded to the prednisone had a sustained response and, thus, all required splenectomy. All 11 patients had an excellent response to splenectomy. The average preoperative and postoperative platelet counts were 19,700 and 498,000, respectively. All patients have maintained normal platelet counts at an average follow-up period of 12.4 months (range of one to 37 months). There were no postoperative deaths. Morbidity was minimal; in two patients, wound seromas developed. In one patient, acquired immunodeficiency syndrome (AIDS) developed 12 months after splenectomy, but none of the other patients have evidence of AIDS. Splenectomy is a safe and effective therapy for HIV-related immune thrombocytopenia.
