Short-term high-dose followed by long-term low-dose hepatitis B immunoglobulin and lamivudine therapy prevented recurrent hepatitis B after liver transplantation.

Hepatitis B immunoglobulin (HBIg) and lamivudine combination has been accepted as the best way to control hepatitis B recurrence after liver transplantation. However, the optimal dose of HBIg and the target titer of hepatitis B surface antibody (HBsAb) remain unclear. We report our satisfactory experience with high-dose HBIg in the early period followed by low-dose HBIg with lamivudine. Subjects comprised five patients with fulminant hepatitis (FH) and 18 patients with liver cirrhosis (LC) who underwent liver transplantation. HBIg at a dosage of 200 IU/kg per day was administered for one week postoperatively. Thereafter, HBIg was administered only for HBsAb titer <100 IU/L. After six months, HBIg was withdrawn in FH and administered in LC only for HBsAb titer <10 IU/L. Lamivudine was administered to two FH and all LC cases. Although two patients with LC showed transient hepatitis B surface antigen (HBsAg) recurrence, all patients remained HBsAg-negative at the final follow-up date. This method allows reliable and cost-effective control of hepatitis B recurrence.
