Hepatitis B (HBV) and C viral (HCV) dual-infection–associated liver disease is an uncommon indication for liver transplantation. The clinical and virologic outcomes in such patients have not been well studied. We retrospectively studied 13 patients with hepatitis B surface antigen (HBsAg) and antibody to HCV positivity who underwent orthotopic liver transplantation (OLT) and survived at least 30 days post-OLT. Antibody to hepatitis delta virus (HDV) was negative in 8 patients (group I) and positive in 5 patients (group II). Eleven of the 13 patients received standard hepatitis B immune prophylaxis, and they all remained HBsAg negative. All group I patients were HCV RNA positive after transplantation; in contrast, all group II patients were HCV RNA negative. Serum alanine aminotransferase levels were elevated in 88% (7 of 8) of the patients in group I compared with 20% (1 of 5 patients) in group II. None of the patients had graft loss from chronic rejection or recurrent hepatitis. Three patients had unsuspected hepatocellular carcinoma in the explant. We conclude that among liver transplant recipients with HBV and HCV coinfection, HDV infection is associated with the suppression of HCV replication and mild inflammatory activity after OLT.
