    Abstract:
    Induction with the use of interleukin-2 receptor monoclonal antibodies may avoid many of the adverse events associated with polyclonal antibodies and significantly impact on rejection-free long-term survival in orthotopic liver transplantation (OLTx). We describe our experience with the use of basiliximab induction therapy in adult OLTx recipients on tacrolimus-based immunosuppression. Forty-six consecutive deceased donor primary OLTx were analyzed. All patients received standard doses of basiliximab, tacrolimus, and steroids. Mycophenolate mofetil was also used as indicated. The mean follow-up period was 17.9 months. Forty-three patients remained rejection-free during follow-up. The actuarial patient and graft survival rate at 2 years was 93%. The rate of histology-proven hepatitis C virus (HCV) recurrence was 24%, with two progressing to severe cholestatic recurrent HCV. None of the study patients developed (cytomegalovirus (CMV) infection or posttransplant lymphoproliferative disease (PTLD). Results were compared to a historical group of 46 OLTx recipients on tacrolimus-based immunosuppression without basiliximab induction. The historical group had a rejection rate of 34% with lower patient and graft survival rates of 71.74% and 69.5%, respectively, at 24 months as well as a higher histological HCV recurrence rate of 77% (17/22), with three patients progressing to graft failure within 2 years. CMV infection and disease developed in 4.5% of the patients. Although PTLD was not observed, three recipients with hepatocellular carcinoma (HCC) developed and died of metastatic HCC. Induction with basiliximab in combination with tacrolimus-based immunosuppressive regimen reduces the incidence of rejection and improves rejection-free survival rate after OLTx without increasing the incidence of CMV, PTLD, or HCV recurrence.
