Abstract

PURPOSE

Hepatic allografts from donors with hepatitis B core antibody have been demonstrated to transmit hepatitis B virus (HBV) infection to recipients after liver transplantation (LT). The efficacy of hepatitis B immune globulin (HBIg) to prevent de novo hepatitis B was investigated by comparing active immunization in the early phase to HBIg monotherapy in the late phase of pediatric liver transplants at Samsung Medical Center.

METHODS

Among pediatric liver transplants, from May, 1996 to June, 2002, 15 recipients who were hepatitis B surface antigen (HBsAg) (-) received an allograft from a donor with hepatitis B core antibody (HBcAb) (+). Except two who died from unrelated causes, eleven of 13 recipients were HBsAb (+), and 2 were naive (HBsAb(-), HBcAb(-)). All patients were vaccinated for HBV before LT. In the early phase (January, 1997~November, 1997, 3 patients), HBsAb (+) recipients received booster vaccination after LT. In the late phase (December, 1997~, 10 patients), all recipients were given booster vaccination and received HBIg therapy in order to maintain HBsAb titer greater than 200 IU/L. Lamivudine was given in one case because of severe side effect of HBIg. We retrospectively analyzed the effect of the preventive therapy for de novo hepatitis B through medical records.

RESULTS

De novo hepatitis B developed in three of 13 recipients (23.1%). All of 3 patients who received active immunization in the early phase became HBsAg (+) at 7~19 months after transplantation. One of them was naive before LT and the other two were HBsAb (+). All of 10 recipients who were given HBIg in the late phase remained HBsAg (-) at 7~55 months' follow-up.

CONCLUSION

Passive immunization with HBIg was effective for prevention of de novo hepatitis B in HBsAg (-) recipients of hepatic allografts from HBcAb (+) donors.
