INTRODUCTION: We aimed to examine the risk of new onset diabetes after transplant (NODAT) associated with the following maintenance immunosuppression regimens in kidney transplant recipients (KTR): 1. tacrolimus + mycophenolate+steroids (Tac+MPA+S); 2. Cyclosporine+mycophenolate+ steroids (CSA+MPA+S); 3. sirolimus+mycophenolate+steroids (SRL+MPA+S); 4. sirolimus+cyclosporine+steroids (SRL+CSA+S) and 5. sirolimus+tacrolimus+steroids (SRL+Tac+S).

MATERIALS AND METHODS: We used an observational cohort design to study 1/3/1995-9/15/2015 adult KTR in the Scientific Registry of Transplant Recipients. With Cox regression, we analyzed the 1-year post-transplant risk of NODAT associated with the discharge immunosuppression regimens: CSA+MPA+S, SRL+MPA+S, SRL+CSA+S and SRL+Tac+S; versus the standard regimen: Tac+MPA+S. We compared NODAT risks between study regimens by estimating the differences in their hazard ratios in the Cox model.

RESULTS: Recipient risk factors for NODAT (Footnote Data, Fig. 1) included: Hep C+ or CMV+ serology, higher BMI or age categories and black or Hispanic race. Compared with basiliximab, ATG or alemtuzumab immunosuppression induction was associated with a lower risk of NODAT.

SRL+Tac+S was associated with a higher, CSA+MPA+S with a lower risk of NODAT than standard maintenance immunosuppression regimen (Tac+MPA+S), (Forest Plot A).

Additional comparisons among maintenance regimens showed that CSA+MPA+S was associated with a lower risk of NODAT than SRL+MPA+S or SRL+Tac+S (Forest Plot-B).

Among SRL regimens, SRL+MPA+S and SRL+CSA+S had comparable NODAT risks, while SRL+Tac+S appeared to be associated with the highest NODAT risk (Forest Plot-B).

CONCLUSION: The risks of NODAT in KTR on steroid-containing regimens varied according to the other component-drugs included in those regimens and these factors may be considered in tailoring immunosuppression prescription for KTR.
