Usefulness of a low-dose intravenous immunoglobulin regimen for the treatment of thrombocytopenia associated with AIDS.

Infection with the human immunodeficiency virus (HIV) frequently is complicated with thrombocytopenia (HIV-Thr) during all stages of the infection. The treatments for autoimmune thrombocytopenic purpura (ITP) are used in HIV-Thr; however, their effects upon the immune status of patients with acquired immunodeficiency syndrome (AIDS) are unknown. Intravenous immunoglobulin (IVIg) is used in patients with ITP and HIV-Thr; however, its usefulness in thrombocytopenic AIDS patients has not been directly addressed.
