Background:
The optimal dose of rabbit anti-thymocyte globulin (r-ATG) in renal transplantation is still under debate. We previously reported that a low-dose r-ATG induction of 3 mg/kg can be used safely and effectively in low-risk kidney transplants with good results in the first year after transplantation compared to basiliximab induction.
Aims:
The purpose of this study is to evaluate the long-term impact of this trial of low-dose r-ATG versus basiliximab on post-transplant outcomes (patient and graft survival, biopsy-proven acute rejection incidence [BPAR], infectious complications, and side effects).
Methods:
Observational study (three-year follow-up) of a 12-month single-center, open-label RCT in de novo kidney allograft recipients assigned to receive either thymoglobulin or basiliximab before transplantation.
Results:
Patients in the basiliximab group (BG) underwent more kidney transplant biopsies than patients in the low-dose r-ATG group (TG) (50 vs. 31.8%, p = 0.07). Although the 12-month cumulative incidence of BPAR was lower in BG, by the end of the three-year follow-up period this incidence was higher (22%) than in the low-dose TG (15%) (p = ns). Steroids were withdrawn more frequently in the TG group and sirolimus was most frequently indicated. Graft function and graft survival were higher in the low-dose TG than in the BG at three-year follow-up but not statistically significant. Patient survival was similar between groups (>90%).
Conclusions:
These three-year follow-up data confirm the efficacy and favorable safety aspects of the low-dose r-ATG (3 mg/kg) in low-risk kidney transplantation.
