Abstract

Physicians in the United States who treat patients with primary immunodeficiency were contacted to identify subjects who had been infected with hepatitis C due to exposure to contaminated intravenous immunoglobulin (IVIg) in 1993-1994. From this survey we gathered information on 58 PCR-positive hepatitis C-infected patients; 37 had CVID, 9 had XIA, 5 were IgG subclass deficient, 4 were antibody deficient with normal immunoglobulin levels, 2 had SCID after BMT, and 1 had B cell linker deficiency. Of the 58 subjects, 30 had been treated with IFN-α in combination with ribavirin in 5 cases, and 26 other subjects were not treated. Of ose who were treated, 11 (37%) resolved the infection and became PCR-negative; of the 26 who were not treated, 5 (19%) have resolved the infection, outcomes not significantly different. Patients 20 years of age or younger had a significantly better outcome compared to those older than age 20 (P = 0.02). Five subjects of the 58 have had a liver transplantation, a sixth has had two transplants, and 10 (17%) of the group have died. This survey demonstrates the heterogeneity of the clinical outcome in subjects with primary immunodeficiency who contracted hepatitis C due to viral contamination of IVIg.
