Up to now the outcomes of liver transplantation in patients with chronic viral hepatitis B have not been very good because the recurrence of viral hepatitis in the graft has been high and resulted in a high early graft failure of liver transplant recipients. However, the administration of a combined therapy with lamivudine and hyperimmune anti-HBs globulin has led to a marked improvement in transplantation results and an increase in the number of liver transplantations for this indication. Four men (aged 47 to 55 years) underwent liver transplantation for cirrhosis, caused by chronic viral hepatitis B, at our centre. All were HBsAg carriers. They were our first patients who received therapy with the combined immunoprophylactic regimen of lamivudine and hyperimmune anti-HBs globulin. HBV DNA negativity was achieved in all patients prior to transplantation; three of them were pretreated with lamivudine. At 4 to 17 months of follow-up, sustained suppression of HBV replication (HBV DNA negativity) was maintained in all four patients. No complications associated with this treatment were observed and no emergence of resistant mutants was detected. The combined therapy for chronic viral hepatitis B administered to liver transplant recipients at our centre showed very good outcomes. However, the development of resistant mutants during this therapy poses a problem, which may hopefully be overcome with the use of new antivirotics, such as adefovir or tenofovir.
