Anti-viral therapy using hepatitis B immune globulin and lamivudine could not prevent HBV recurrence after liver transplantation (LT) completely. Adefovir dipivoxil is a acyclic nucleotide phosphate analogue and known to have potent anti-HBV effect. In this study, we analyzed the therapeutic effect of adefovir for recurrent or de novo HBV infection after LT.


From December 2002 to October 2004, adefovir was administered in 12 post-LT patients of HBV infection (11 recurrent and 1 de novo infection). In these patients, lamivudine and other combined therapies were used before the introduction of adefovir. Thereafter, adefovir combined with lamivudine was administered to all patients.


The duration of adefovir administration was 5.5-18 (median, 15.5) months. The median values of serum AST and ALT levels were significantly reduced from 86+/-80 IU/L and 140+/-103 IU/L, respectively before the adefovir administration to 42+/-19 IU/L and 38+/-33 IU/L after 2 months of administration. This trend of improved liver function persisted throughout the follow-up period. HBeAg seroconversion was achieved in 4 of 10 patients (40%) and HBsAg seroconversion was observed in 1 of 10 patients (10%). HBV DNA levels have decreased to undetectable levels by hybridization assay in 6 of 7 patients within the first 2 months of therapy. Nephrotoxicity and hypophosphatemia were not found in all of these patients.


Based on this preliminary result, adefovir dipivoxil seems to be an effective and safe antiviral agent leading to viral inhibition and clinical improvement in post-LT patients with recurrent or de novo HBV infection.
