Liver allografts from donors previously exposed to hepatitis B virus (HBV) carry the risk of transmission of HBV infection to immunosuppressed recipients. However, exclusion of donor candidates with the serologic evidence of resolved hepatitis B-HBV surface antigen (HbsAg) negative and HBV core antibody (anti-HBc) positive-is not feasible in countries endemic for HBV.
Aim: Our aim was to assess the safety of living donor liver transplantation from anti-HBc positive donors.
Materials and methods: In our institution, 152 transplants were performed between June 1999 and April 2004. Fifty-six (37%) of the living donors were anti-HBc positive. Twenty of these liver grafts were transplanted to HbsAg-negative recipients. We excluded four HBsAg negative recipients who died because of early complications after transplantation. Lamivudine (100 mg/day) was given for prophylaxis of de novo HBV infection.
Results: The mean follow-up time for 16 HBsAg-negative recipients was 21.7 (7-48) months. None of them experienced de novo HBV infection.
Conclusion: The use of liver allografts from anti-HBc-positive living donors is reasonably safe in HBsAg-negative recipients under lamivudine prophylaxis.
