Hepatitis C virus infection associated with administration of intravenous immune globulin. A cohort study.

Abstract

Gammagard was the only IGIV product implicated in the transmission of HCV. Infection was associated with higher quantities of HCV RNA in Gammagard produced from second-generation anti-HCV-screened plasma. Further studies are needed to determine reasons for the infectivity of Gammagard, and viral inactivation and removal steps are needed to ensure the safety of IGIV products.
