INTRAVENOUS IMMUNOGLOBULIN IN THE TREATMENT OF HUMAN IMMUNODEFICIENCY VIRUS-RELATED THROMBOCYTOPENIA

Fourteen patients with sexually transmitted human immunodeficiency virus (HIV)-related immune thrombocytopenia were treated with intravenous gammaglobulin (VIG). The patients were treated with a uniform program consisting of 1 g/kg of IVIG on day 1 and day 2, followed by 1 g/kg on day 15. Most patients had pretreatment bleeding symptoms, which included petechiae, spontaneous and traumatic ecchymoses, gum bleeding, and epistaxis. Median baseline platelet count was 17,000/mm3 (range 3-61,000/mm3). After the infusion of the IGIV, all patients had a resolution of their bleeding by day 8. The median maximum platelet count achieved with the IGIV was 220,000/mm3 (range 76-426,000/mm3). No patient achieved either a sustained complete or partial remission after the conclusion of the IVIG therapy. Toxicities were minimal with the majority being headache and nausea. In conclusion, patients with sexually transmitted HIV infection and immune thrombocytopenia respond favorably to IVIG. This treatment should be considered as first-line therapy for patients with HIV-related immune thrombocytopenia who require immediate but temporary increase in their platelet count, attributable to symptoms or signs of clinical bleeding or because of the need for an invasive procedure.
