Anti-D for Treating Thrombocytopenia in Adults Infected With Hepatitis C Virus With or Without HIV Co-Infection

Brief Summary
Thrombocytopenia occurs when a person's blood has a decreased number of platelets, which are cells involved in blood clotting. This condition may lead to uncontrolled bleeding and can be fatal. Thrombocytopenia commonly occurs with hepatitis C virus (HCV) infection or as a result of standard HCV treatment. Anti-D is an antibody approved by the Food and Drug Administration (FDA) for the treatment of HIV-related thrombocytopenia. The purpose of this study is to determine the safety and effectiveness of intravenous anti-D for the treatment of thrombocytopenia in patients with HCV infection who are starting or already undergoing treatment with peginterferon alfa-2 and ribavirin. This study will recruit HCV patients both with and without HIV co-infection.

EXPERIMENTALParticipants will be given anti-D in an outpatient setting. Participants will be observed for any adverse effects for 1 hour postinfusion. Some participants may require additional doses of anti-D later in the study, depending on individual response to the drug; participants may receive 1 to 6 doses of anti-D.
