    Abstract:
    The clinical outcomes of 2,054 renal recipients were examined retrospectively based on pre-transplant hepatitis B surface antigen (HBsAg) status to investigate the efficacy of lamivudine treatment in HBsAg positive recipients. Pre-transplant HBsAg positivity was documented in 66 recipients. The 10-year patient and graft survival rates in Ag positive group were significantly lower than those of Ag negative group (64.4/36.6% vs. 88.2/70.5%, respectively, P < 0.0001). Since 1997, lamivudine was used when hepatitis B virus polymerase chain reaction (HBV PCR) was positive or when the level of post-transplant viral load rose. Lamivudine given to 27 recipients markedly improved both 10-year patient and graft survivals compared to Ag positive renal recipients who did not take lamivudine (85.3/59.2% vs. 49.9/22.7%, respectively, P < 0.0001). Overall, 13 viral breakthroughs among 24 lamivudine-responsive patients were observed. The cumulative incidence of viral breakthrough at 60 months was 53.3%. Adefovir rescue in three viral breakthroughs patients induces virological response and restoration of liver function. In 10 patients who did not changed to adefovir, 6 patients are alive with elevated liver enzymes. In conclusion, in the era of lamivudine and adefovir, renal transplantation in HBsAg positive end-stage renal disease patients should not be abandoned.
