Prevention of hepatitis B recurrence with indefinite hepatitis B immune globulin (HBIG) prophylaxis after liver transplantation.

Liver transplantation for hepatitis B is followed by a high rate of recurrence some time after transplantation, resulting in poor outcome compared to liver recipients transplanted for other indications. Passive immunoprophylaxis with HBIG has been shown to decrease the rate of recurrence to 25-50%, but the intensity and length of treatment is still controversial. We studied 17 HBsAg positive patients who were transplanted for hepatitis B. Four did not receive immunoprophylaxis and they all reoccurred within 3 months. The remaining 13 have received indefinite, high dose HBIG (10,000 mu or 40,000 mu/dose depending on HBV DNA status pretransplant). Ten of 13 patients (77%) remain HBsAg negative after a mean follow-up of 16.7 months with six of these ten patients being HBV DNA positive pretransplant. Of the three who have experienced recurrence, two received extensive additional immunosuppression beyond that normally administered to transplant patients (chemotherapy, multiple antirejection treatment). The last patient received 110,000 u of HBIG during the first 3 months, which produced an anti-HBs titer level of 225 IU/L, but the following month he was HBsAg positive with an anti-HBs titer of 13 IU/L. We conclude that HBsAg positive patients can be safely transplanted using indefinite, high-dose HBIG prophylaxis, and that with adequate HBIG it is possible to prevent recurrence in HBV DNA positive patients as well.
