Background: The aim of this study was to compare single-dose rabbit anti-thymocyte globulin (rATG) with a divided dose in kidney transplant recipients within a majority Black patient population.
Methods: We analyzed the outcomes before and after a change in protocol from divided-dose (1.5 mg/kg/day over 4 days) to single-dose (6 mg/kg over 24 hours) rATG in a retrospective cohort study. All patients who received rATG for kidney transplant induction between December 2015 and July 2018 were included.
Results: A total of 197 patients (n = 98 in the divided-dose group, n = 99 in the single-dose group) received rATG. There was no difference in time to rejection at 1 year (P = .82) or incidence of rejection (P = .80). There was also no difference in delayed graft function, serum creatinine, or survival at 1 year. Patients in the single-dose group were more likely to leave the hospital by postoperative day 3 (12% vs 2%, P = .006). The cytomegalovirus infection rate was higher in the single-dose group (P = .031).
Conclusions: Use of a single-dose rATG regimen is an acceptable accelerated induction compared with the standard divided dose for induction therapy in kidney transplant in a predominantly Black population.
