ObjectivesThis study explored the safety of early steroid withdrawal in recipients of expanded criteria deceased-donor kidney transplants.Materials And MethodsUsing the Organ Procurement and Transplant Network-United Network of Organ Sharing database, we identified patients who underwent expanded criteria deceased-donor kidney transplant between January 2000 and December 2008 after receiving induction with rabbit-antithymocyte globulin (n = 3717), alemtuzumab (n = 763), or interleukin 2 blocking agent (n = 2600) followed by calcineurin inhibitor and mycophenolate mofetil-based maintenance with and without steroid therapy.ResultsAdjusted overall graft survival (hazard ratio 1.32; 95% confidence interval, 1.1-1.56; P = .002) and patient survival (hazard ratio 1.46, 95% confidence interval, 1.16-1.83, P = .001) were inferior, whereas death-censored graft survival (hazard ratio 1.13; 95% confidence interval, 0.87-1.47; P = .35) was similar for chronic steroid maintenance versus early steroid withdrawal groups in rabbit-antithymocyte globulin-induced patients. Graft and patient outcomes were similar for chronic steroid maintenance versus early steroid withdrawal groups among alemtuzumab and interleukin 2 blocking agent-induced patients. Among rabbit-antithymocyte globulin-induced patients, adjusted overall graft survival (hazard ratio 1.57; 95% confidence interval, 1.2-2.0; P < .001) and patient survival (hazard ratio 1.5; 95% CI, 1.15-2.1; P = .004) were inferior, whereas death-censored graft survival (hazard ratio 1.5; 95% confidence interval, 0.97-2.43; P = .07) trended inferior for chronic steroid maintenance versus early steroid withdrawal groups in recipients > 60 years old (n = 1729).ConclusionsOur study showed safety of early steroid withdrawal in recipients of expanded criteria deceased-donor kidney transplants who underwent perioperative induction followed by calcineurin inhibitor and mycophenolate mofetil maintenance. Among rabbit-antithymocyte globulin-induced patients, chronic steroid maintenance was associated with inferior graft and patient outcomes, an effect limited to older recipients.
