    Steroid-Avoidance Immunosuppression Regimen in Live-Donor Renal Allotransplant Recipients: A Prospective, Randomized, Controlled Study

    Objectives: Steroids have occupied a major role in renal transplantation for more than 4 decades. However, chronic use of steroids is associated with numerous comorbidities. We sought to elucidate the safety and efficacy of a steroid-free immuno­suppression regimen in live-donor renal transplant recipients. Patients and Methods: One hundred patients were randomized to receive tacrolimus, mycophenolate mofetil, basiliximab induction, and steroids only for 3 days (experimental group, n=50 patients) or tacrolimus, mycophenolate mofetil, basiliximab induction, and steroid maintenance (control group, n=50 patients,). The median follow-up was 12 months. Results: Patient and graft survival rates were 100% in both groups. The rate of biopsy-proven acute rejection was 16% in both groups. For patients in the control group, the mean serum creatinine level was 111.22 µmol /L compared with 110.39 µmol/L in patients in the experimental group. Post­transplant hypertension was encountered in 4% of the patients in the experimental group compared with 24% of the patients in the control group (P = .0009). Post­transplant diabetes mellitus was detected in 4% of the patients in the experimental group compared with 16% of the patients in the control group (P = .037). Posttransplant weight gain was reported in 6% of the patients in the experimental group compared with 15% of the patients in the control group (P = .001). The chronic allograft damage indexes of biopsy specimens at 1-year follow-up were comparable in both groups (2.48 vs 2.28, respectively) (P = .16). Conclusions: In living-donor renal transplant recipients with low immunologic risk, steroid avoidance (using basiliximab induction, tacrolimus, mycophenolate mofetil maintenance, and 3 days’ steroid treatment) is feasible, safe, and carries with it fewer morbidities compared with the same immuno­suppressive protocol with steroid maintenance. Longer follow-ups are required to prove the safety of this regimen.

    Steroid Avoidance in Renal Transplant Patients Maintained on a Cyclosporine-based Protocol
    (2007-12) Ko, Tina Y; Julie A Haddy,; Sureshkumar, Kalathil K.; Breckenridge, Molly; Patel, Satish; Marcus, Richard J.; Sandroni, Stephen E.; McGill, Rita L.; Carpenter, Barbara J.; Nghiem, Dai D.
    Objective: The aim of this study was to analyze the effect of steroid avoidance, as compared with our pre-existing protocol that contained steroids, on renal allograft and patient survival. Secondary outcomes included body weight, diabetes, hyperlipidemia, and infection. Materials and Methods: This retrospective chart review of the results of steroid avoidance was performed in 169 patients who had undergone renal transplant between January 2000 and March 2002 and had received an immunosuppression regimen of cyclosporine, mycophenolate mofetil, and pred­nisone; and 148 patients who had undergone transplant between November 2002 and November 2004 who had received induction immuno­suppression with a steroid taper by postoperative day 4 and were maintained on cyclosporine and mycophenolate mofetil. Results: One-year allograft survival rates, rejection-free graft survival rates, and patient survival rates were 88%, 76%, and 97%, respectively, in the steroid-maintenance group compared with 90%, 74%, and 96%, respectively, in the steroid-avoidance group (P = NS). No differences were detected in multiple secondary variables related to the metabolic effects of steroid therapy. Conclusions: These data suggest that steroid avoidance can be performed safely and effectively in patients on a cyclosporine-based protocol of immuno­suppression. Longer follow-ups are suggested to determine the effects of limited steroid exposure on the metabolic profiles of patients.
