Background: The increasing demand for transplantation has resulted in a trend toward using virologically compromised donors. We reviewed our experience with liver grafts from hepatitis-B surface antigen (HBsAg)(-), antibody to core antigen (anti-HBc)(+) donors.
Methods: Sixty-two liver transplants using HBsAg(-), anti-HBc(+) donors were studied. The decision to use prophylaxis was based on the presence or absence of donor and recipient risk factors for posttransplant hepatitis-B virus (HBV) transmission or reinfection. If the donor or recipient showed positive HBVDNA, hepatitis-B immunoglobulin (HBIg) and lamivudine were used. If both donor and recipient HBVDNA were negative, a choice between lamivudine and no prophylaxis was made on the basis of presence or absence of HBsAg and antibody to the surface antigen (anti-HBs) in the recipient.
Results: No death or graft loss could be ascribed to HBV. Mild HBV infection occurred in two patients who were not taking the recommended prophylaxis. Among the other 60 patients, 1 showed positive e antigen (HBeAg) early after transplantation, and 2 (1 with recurrent cancer, 1 with HIV infection) showed HBsAg(+). None of the three patients had any other evidence of HBV infection. Forty-seven patients underwent liver biopsies. Changes consistent with hepatitis were observed in 26, and 24 had HCV infection; immunostains for HBV antigens were negative in all cases, and 7 showed positive HBVDNA.
Conclusions: A selective protocol based on donor and recipient risk factors for post-liver transplant HBV infection can prevent hepatitis-B infection and avoid unnecessary administration of antiviral prophylaxis in recipients of HBsAg(-), anti-HBc(+) liver allografts.
