Discontinuation of steroids in ABO-incompatible renal transplantation.

A steroid-free protocol for ABO-compatible renal transplantation has been used at our center since 1983. To minimize the adverse effects of steroids, we also developed a steroid sparing protocol for ABO-incompatible renal transplantation in 2008. The present study is a report of our results. A retrospective review of the first 50 ABO-incompatible renal transplantations performed at a single university center. If no immunological events occurred in the post-transplant period, prednisolone tapering was initiated approximately 3 months after transplantation. Forty-three patients completed prednisolone tapering after 289 ± 58 days. Three patients died during follow-up, and four patients lost graft function. None of these adverse events were rejection related. Eleven patients experienced rejections; seven were on prednisolone and four were after weaning from prednisolone. All patients responded well to antirejection treatment. Overall, 1-year rejection rate was 19%. One- and 3-year graft survival was 94% and 91%, respectively. One-year post-transplant median serum creatinine was 123 μmol/L. We found acceptable rejection rates, graft survival, and creatinine levels in patients undergoing ABO-incompatible renal transplantations with a steroid sparing protocol. However, a longer follow-up of a lager cohort is needed before firm conclusions can be made.
