Early steroid withdrawal in repeat kidney transplantation.

BACKGROUND AND OBJECTIVES: Kidney re-transplantation (KRT) candidates are considered at high risk for graft failure. Most of these patients are kept on a chronic steroid maintenance (CSM) regimen. The safety of early steroid withdrawal (ESW) remains unanswered in KRT.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: This study was aimed at comparing the outcomes of ESW and CSM in KRT. Retrospective analysis of 113 KRT patients (ESW, n=59; CSM, n=54) was performed. All patients received rabbit anti-thymocyte globulin/steroid induction and were maintained on mycophenolate/tacrolimus (±steroids).

RESULTS: One- and 5-year patient survival for the ESW and the CSM group were not significantly different (98 versus 96% and 91 versus 88%, respectively; P=0.991). No significant difference was seen in the graft survival for both groups at 1 and 5 years (98 versus 93% and 80 versus 74%, respectively; P=0.779). Mean 1- and 5-year estimated GFR was not statistically different between the groups (P=0.773 and 0.790, respectively). The incidence of acute rejection at 1 year was 17 and 22% in ESW and CSM patients, respectively (P=0.635). Compared with the ESW group, patients in the CSM group were more likely to be hyperlipidemic (P=0.044), osteoporotic (P=0.010), post-transplant diabetics (P=0.051) and required more medications to control BP (P=0.004).

CONCLUSIONS: ESW seems to be a reasonable approach in KRT recipients because the short and intermediate patient survival, graft survival, and graft function is comparable to CSM immunosuppression.
