Introduction: Deceased donor renal transplantation (DDRT) poses special immunological challenges; particularly in resource-poor scenarios. There is substantial evidence that rabbit antithymocyte globulin (rATG) is superior to interleukin-2 receptor blocker and placebo among patients at high immunological risk. However, due to the lack of randomized controlled trials, this remains controversial in DDRT maintained on tacrolimus/mycophenolic acid/steroids. Here, in this study, we compared the clinical outcomes of induction with rATG therapy to no-induction therapy. Methods: The study was a single-center, retrospective cohort study. A total of 62 patients were divided into two groups, based on induction immunosuppression; induction with rATG (N = 25) and no-induction group (N = 37). Both groups received tacrolimus/mycophenolate mofetil sodium/prednisolone as maintenance immunosuppression. The main outcomes were incidence of acute rejection (AR) within the first year and graft survival at the end of 1 year. Results: The AR at the end of 1-year was reported as 8% and 27% for the induction and no-induction groups (P = 0.07), respectively. A total of 15 patients died. Patient survival rates at 12 months were 83.8% (no-induction) and 64.0% (induction; P = 0.094). Death-censored graft survival rates, 12 months after transplantation, were similar in both treatment groups (83.7% vs. 83.5%, P = 0.972). The incidence of death with functioning graft was significantly high in the induction group (28% vs. 5.4%, P = 0.045). Conclusion: The incidence of AR was less in patients who received rATG induction compared with patients who did not receive any form of induction. An added advantage of induction with ATG in terms of reduced incidence of AR must be weighed against high incidence of infection, death with functioning graft, and death. [ABSTRACT FROM AUTHOR]
