Abstract

Methods: We used national transplant registry data to study clinical correlates and outcomes of single versus dual induction therapy in adult kidney-only transplant recipients in the United States (2005-2018). The risk of death and graft loss at 1 and 5 y, according to induction therapy type, was assessed using multivariate Cox regression analysis (adjusted hazard ratio with 95% upper and lower confidence limits [aHR]).

Results: Of the 157 351 recipients included in the study, 67% were treated with ATG alone, 29% were treated with IL2rAb alone, and 5% were treated with both. Compared with IL2rAb alone, the strongest correlates of dual induction included Black race, calculated panel reactive antibody ≥80%, prednisone-sparing maintenance immunosuppression, more recent transplant eras, longer cold ischemia time, and delayed graft function. Compared with ATG alone, dual induction was associated with an increased 5-y risk of death (aHR 1.15;  < 0.0001), death-censored graft failure (aHR 1.13;  < 0.05), and all-cause graft failure (aHR 1.12;  < 0.0001).

Conclusions: Further research is needed to develop risk-prediction tools to further inform optimal, individualized induction protocols for kidney transplant recipients.
