Abstract

Objectives: We review different immunosuppressant protocols used for living-donor kidney transplant recipients at our center. Materials and Methods: Many prospective randomized studies from our center have been reported between March 1976 and 2016, with more than 2700 renal transplant procedures conducted. The first study was a prospective randomized trial of azathioprine versus cyclosporine. The second study compared triple therapy (prednisolone + azathioprine + cyclosporine) versus conventional therapy (prednisolone + azathioprine). The third study was a cost-saving study, in which 100 patients received ketoconazole along with the triple regimen. Another trial demonstrated the advantages of a microemulsion form of cyclosporine. A subsequent trial compared calcineurin inhibitor minimization versus avoidance protocols. Rescue therapies were carried out to intensify immunosuppressive regimens after repeated rejection. In addition, steroid-free regimens were evaluated during both short-and long-term treatment. A recent trial reported a step-forward avoidance protocol with a calcineurin inhibitor and a steroid-free regimen, whereas another current study is the TRANSFORM one. The rationale behind antibody therapy was tho roughly evaluated among living-donor renal trans plant recipients with different agents, including basiliximab, daclizumab, antithymocyte globulin, and alemtuzumab.Results: Earlier studies have demonstrated the efficacy of conventional regimens without induction therapy, especially in longer follow-up. The standard triple therapy has emerged with intensified immunosuppressive and lowered dose of each drug, especially cyclosporine. In minimization studies, no significant differences were encountered regarding patient and graft survival, even in the long-term. Steroid avoidance was safe and effective. Calcineurin inhibitors and steroid-free regimens have shown comparable patient and graft survival. Induction therapy has lowered the incidence and severity of acute rejection. Conclusions: A better 5-year graft survival and less posttransplant complications have been achieved with steroid avoidance after induction with basiliximab. Induction therapy did not affect graft and patient survival rates despite lowered incidence and severity of acute rejections.

“…By tailoring these regimens to balance the prevention of graft rejection with the risk of UTIs, healthcare providers can minimize the likelihood of post-transplant UTIs while preserving graft function. Achieving this balance is critical for the long-term success of the transplant [ 50 ].…”
