Abstract: Background: The aim of this study is to examine the efficacy of long‐term prophylaxis with lamivudine (LAM) after a course of post‐operative hepatitis B immunoglobulin (HBIG) in patients who underwent liver transplantation (LT) for hepatitis B virus (HBV)‐related disease. Result: The medical records of HBV‐infected patients who underwent a LT in our institution between July 2001 and May 2005 were reviewed. There were 15 liver transplant recipients who were administered HBIG for <18 months and used LAM as a maintenance prophylaxis regime enrolled in this study. At enrollment, all patients were hepatitis B surface antigen (HBsAg) positive and three patients were HBeAg positive. There were 13 patients who were HBV DNA positive with a mean viral load of 5.4 log copies/mL, and among them, 12 recipients were on antiviral therapy with LAM (100 mg/d orally) for 12–168 d, resulting in HBV DNA negative levels in nine patients prior to their transplant. HBV recurrence post‐LT was noted in two patients who had very high‐HBV DNA levels pre‐LT. Both of these patients showed LAM‐resistant mutation at the time of recurrence. The 11 patients who were HBV DNA negative before LT (low‐risk patients) had no HBV recurrence during a follow‐up at a median of 58 months post‐LT. This included five patients who had intermittent low‐level HBV DNA post‐LT (HBsAg negative), of whom two had YMDD mutation and these two were given adefovir in addition to LAM. Conclusion: Our retrospective study demonstrated excellent long‐term outcomes in the low‐risk patients treated with LAM after a short course of HBIG.
