Kidney transplantation in HIV‐positive patients treated with a steroid‐free immunosuppressive regimen

Summary One of the main concerns associated with renal transplantation in HIV-infected patients is the high risk of acute rejection, which makes physicians reluctant to use steroid-free immunosuppressive therapy in this subset of patients. However, steroid therapy increases cardiovascular morbidity and mortality. The aim of this study was to define the efficacy of a steroid-sparing regimen in HIV-infected renal transplant recipients. Thirteen HIV-infected patients were consecutively transplanted. The induction therapy consisted of basiliximab and methylprednisolone for 5 days followed by a calcineurin inhibitor plus mycophenolate acid. The mean follow-up was 50 ± 22 months. Eight patients (61.5%) experienced acute rejection, and 75% of the first episodes occurred within 2 months after transplantation. The probability of first acute rejection was 58% after 1 year and 69% after 4 years. Seven of eight patients recovered or maintained their kidney function after antirejection therapy and steroid resumption. At the last follow-up, seven of 13 patients (54%) had resumed steroid therapy. The 4-year patient and graft survivals were 100% and 88.9%, respectively. The benefits of this steroid-free regimen in HIV-infected renal recipients must be reconsidered because of the high rate of acute rejection. New immunosuppressive steroid-free strategies should be identi-fied in this set of patients.
