Abstract
The use of hepatitis B core antibody–positive (HBcAb+) grafts for liver transplantation (LT) has the potential to safely expand the donor pool, as long as proper prophylaxis against de novo hepatitis B (DNHB) is employed. The aim of this study was to characterize the longterm outcome of pediatric LT recipients of HBcAb+ liver grafts under a prophylaxis regimen against DNHB using hepatitis B virus (HBV) vaccine and hepatitis B immunoglobulin (HBIG). From June 1996 to February 2013, 49 patients receiving pediatric LT at our center were from HBcAb+ donors. Forty-one patients who received DNHB prophylaxis according to our protocol were included in this analysis. Our DNHB prophylaxis protocol consists of HBV vaccine intramuscular injections given intermittently to maintain anti–hepatitis B surface antibody (HBsAb) titers above 100 IU/L. HBIG was also used during the first posttransplant year with a target anti-HBsAb titer level above 200 IU/L. There were 19 boys and 22 girls. Median age was 1.0 year (range, 4 months to 16 years). Median follow-up time was 66 months after transplant. Median annual number of HBV vaccine injections was 0.8 per year (range, 0-1.8 per year). Four patients did not require any HBV vaccine injections during follow-up. One patient with DNHB was encountered during the follow-up period (1/41, 2.4%). DNHB was diagnosed at 3.5 years after transplant, when hepatitis B surface antigen was positive upon routine follow-up serologic testing. Anti-HBsAb titer was 101.5 IU/L at the time. No grafts were lost because of DNHB-related events. Overall survival of the 41 recipients of HBcAb+ grafts who received DNHB prophylaxis was 92.3% at 10 years after transplant. In conclusion, longterm prophylaxis against DNHB with HBV vaccine in pediatric LT recipients of HBcAb+ grafts was safe and effective in terms of DNHB incidence as well as graft and patient survival.
