Abstract

Abstract : Background: Steroid avoidance in kidney transplantation has been proven noninferior. Long-term outcome data on steroid avoidance in simultaneous pancreas-kidney (SPK) remains scant. Methods: Utilizing the Scientific Registry of Transplant Recipients between 2000 and 2020, we studied all primary crossmatch negative SPK recipients (N = 5683) who received antithymocyte globulin induction and were discharged alive with functioning grafts on tacrolimus and mycophenolate ± steroid maintenance. Recipients were grouped according to steroid use into 2 groups: steroid maintenance (n = 4191) and steroid avoidance (n = 1492). Kaplan-Meier curves censored at 10 y were generated for recipient and allograft survival by steroid maintenance. Predictors for recipient and graft survival were examined using Cox Proportional Hazards. Models were adjusted for age, body mass index, ethnicity, diabetes type, human leukocyte-antigen mismatches, cold ischemia time, transplant era, preemptive transplantation, and pancreas donor risk index with the transplant center included as a random effect. Results: Steroid avoidance gained popularity over time, accounting for over one-fourth of the studied cohort. One-year acute rejection rates by steroid avoidance were comparable for kidney (8.6% versus 9%, P = 0.783); however, the pancreas rejection rate was lower in the steroid avoidance group (7.9% versus 10%; P = 0.035). After adjustment, steroid avoidance did not influence recipient survival (lower level of confidence interval, adjusted hazard ratio, upper level of confidence interval: 0.94, 1.15, 1.39), pancreas (0.75, 0.93, 1.16), or kidney (0.95, 1.18, 1.45) death-censored survival, compared with steroid maintenance. Conclusions: Accounting for the recipient and graft characteristics, steroid avoidance is associated with similar recipient, pancreas, and kidney graft outcomes compared with steroid maintenance in SPK recipients after antithymocyte globulin induction with tacrolimus and mycophenolate maintenance.
