Clinical course of concomitant Hbv and Hcv infection in renal allograft recipients.

We evaluated the impact of concomitant infection with Hepatitis B virus (HBV) and Hepatitis C virus (HCV) on the clinical course after renal transplantation (Tx). In 335 patients (pts) transplanted between 1991 and 1993 we found 30 (9%) recipients who were positive for Hepatitis B surface antigen (HBsAg) (ELISA, Organon) and anti-HCV antibodies (immunoblot assay Lia Tek) preTx. Chronic liver disease (CLD) (two-fold or greater increase in serum ALT and AST levels for at least six months) developed in 40.
