Clinical Outcomes and Risk Factors of Hepatitis B Virus Recurrence in Patients Who Received Prophylaxis With Entecavir and Hepatitis B Immunoglobulin Following Liver Transplantation

Introduction. Although entecavir (ETV) and hepatitis B immunoglobulin (HBIG) have widely been used for prophylaxis of hepatitis B virus (HBV) recurrence following liver transplantation (OLT), there have been few. studies about clinical outcomes and risk factors of HBV recurrence. Materials and methods. This study retrospectively assessed clinical outcomes and identified risk factors of post-transplant HBV recurrence in 154 patients who received prophylaxis with both ETV and HBIG after OLT. Results. The median follow-up duration was 28.0 months (range, 1.0-57.8). Posttransplant HBV recurrence occurred in 5 patients (3.2%) without any ETV-resistant mutants. The overall rates of HBV recurrence at 1, 2, and 4 years were 0.6%, 1.6%, and 6.2%, respectively. We found that recurrent hepatocellular carcinoma (HCC) was an independent risk factor of HBV recurrence (hazard ratio = 13.5, 95% confidence interval, 2.4-74.4; P =.006). Conclusions. Prophylaxis with a combination of ETV and HBIG resulted in a low HBV recurrence rate following OLT without any emergence of ETV-resistant mutants. Recurrent HCC was an independent risk factor of HBV recurrence in patients who received prophylaxis with both ETV and HBIG for prophylaxis following OLT.
