| Abstract: | Background. Bone marrow transplantation (BMT) is effective treatment for many hematologic disease, but performed in a population with a high endemic hepatitis B virus carrier rate, the incidence of liver function impairment and fulminant hepatitis (FH) is expected to be raised. Methods. Forty three hepatitis B virus carriers received high-dose chemotherapy and BMT, 32 patients received an allogeneic graft, and 11 patients autologous marrow. Acute graft-versus-host disease prophylaxis consisted of methotrexate on day 1, 3, 6, and 11 and cyclosporine for B months. Results. After a median follow-up period of 68 months (range: 1-11.5 years), 26 (81.3%) allogeneic BMT patients developed impaired liver function (LF), 5 progressed to FH on day 93, 169, 170, 180, and 468, respectively, and died after an average of 13.8 days (range: 1-45 days). Whereas only 4 (36.4%) autologous BMT patients developed impaired LF, and none FH, Impaired LF (P=0.026, chi-square), and FH (odds ratio=12.86, P=0.009 for coefficient) were significantly related to an allogeneic marrow graft, and the timing of liver function impairment coincided with cyclosporine withdrawal. Hepatitis B surface antigen (HbsAg) disappeared from the serum in 4/14(28.6%) patients receiving a marrow graft from an HbsAg+ donor, HbsAg was not detected in the serum after BMT in 2/11 (18.2%) autologous BMT patients. Conclusions. Hepatitis B virus carriers receiving a marrow graft from an HbsAg+ donor have a significantly increased risk of FH. |
