Quadruple immunosuppression with basiliximab, tacrolimus, mycophenolate mofetil and prednisone is safe and effective for renal transplantation

Introduction: Recent immunosuppression with tacrolimus and mycophenolate mofetil has improved the results of renal transplantation. In this study, we analyzed the effect and safety of basiliximab as an induction therapy. Material and methods: Forty-nine kidney recipients were given tacrolimus, mycophenolate mofetil and prednisone (non-Bas group), and 31 recipients were given basiliximab as an induction therapy in addition to the triple immunosuppressants (Bas group). Graft function, incidence of acute rejection (AR), findings of protocol graft biopsy and adverse effects were compared. Results: Serum creatinine within 1 yr post-transplant was comparable between the two groups. Incidence of biopsy-proven AR within 6 months post-transplant was less in the Bas group than in the non-Bas group. Borderline change at 3 months post-transplant was less in the Bas group when compared to the non-Bas group. The frequency and severity of tubulitis were higher in the non-Bas group than in the Bas group. The addition of basiliximab did not increase opportunistic infection, but reduced tacrolimus nephrotoxicity. Conclusion: The addition of basiliximab to the tacrolimus-based triple immunosuppressive regimen enabled us to reduce the doses of immunosuppressants and tacrolimus nephrotoxicity without increasing early rejection or infection. This regimen is safe and effective for application during the early period after renal transplantation.
