title: HBV DNA persistence 10 years after liver transplantation despite successful anti-HBS passive immunoprophylaxis.
abstract: Long-term immunoprophylaxis with hepatitis B immune globulin (HBIG) is widely accepted for the prevention of recurrent hepatitis B virus (HBV) infection after liver transplantation in HBV-infected patients without viral replication. We report long-term results of HBIG administration in 284 hepatitis B surface antigen (HBsAg)-positive transplant patients. In protocol 1, 259 patients were given HBIG with the goal of maintaining the anti-HBs antibody (Ab) titer over 100 IU/L. After December 1993, 25 HBV DNA-positive patients received HBIG, with a target anti-HBs Ab titer over 500 IU/L, combined with posttransplantation antiviral therapy (protocol 2). At 10 years, 44 patients without recurrence were tested for the presence of HBV DNA in serum using real-time polymerase chain reaction (PCR); 28 were also tested in liver and peripheral blood mononuclear cells (PBMC). The overall 5- and 10-year posttransplantation actuarial rates of HBV recurrence were 24.2% and 25.4%, respectively. The 5-year recurrence rate in protocol 2 patients was 11.8%. On multivariate analysis, predictors of lower HBV recurrence risk were absence of serum HBV DNA before transplantation (P <.0001), acute liver disease (P =.0037), HDV superinfection (P =.012), and protocol 2 therapy (P <.0001). Low-level HBV DNA was detected by PCR in 45.4% of patients without HBV recurrence at 10 years. Overall actuarial 10-year survival was 74.4%. In conclusion, we confirm the efficacy of long-term HBIG immunoprophylaxis. Combination prophylaxis with HBIG and antiviral therapy is effective in patients with viral replication. Although there were only a few cases of HBV recurrence after 5 years, HBV DNA remained present in 45% of patients at 10 years.
