RESUMO
OBJECTIVES: Steroids have played a major role in renal transplantation for more than 4 decades. However, chronic use of steroids is associated with many comorbidities. This study aimed to assess the costs and benefits of a steroid-free immunosuppression regimen in a prospective randomized controlled study of living-donor renal transplantation, which was lacking in the literature. MATERIALS AND METHODS: In our study, 428 patients were enrolled to receive tacrolimus (Tac), mycophenolic acid (MPA), basiliximab (Simulect, Novartis, Basel, Switzerland) induction and steroids only for 3 days (214 patients, study group) and steroid maintenance (214 patients, control group). Median follow-up was 66 ± 41 months. RESULTS: We found that both groups showed comparable graft and patient survival, rejection episodes, and graft function. Posttransplantation hypertension was detected in 40% of the steroid-free group and 80% of the steroid maintenance group (P = .05), whereas posttransplantation diabetes mellitus was detected in 5% and 15% of these 2 groups, respectively (P = .3). CONCLUSIONS: Among low-immunological-risk recipients of living-donor renal transplants, steroid avoidance was feasible, safe, and had less morbidity outcome using Simulect induction, then Tac and MPA as maintenance immunosuppression. Steroid avoidance was associated with a lower total cost despite comparable immunosuppression cost, which was attributed to the lower cost of associated morbidities.
