There are few prospective studies comparing outcomes of anti T-lymphocyte immune globulin (ATLG) and IL-2RB (Basiliximab) in living related kidney transplant recipients (LRTR).
This was an ethically approved, prospective, observational report with probability-based sampling excluding deceased donor, sensitized, and poor mismatch groups. Primary outcome measured was Biopsy proven acute rejection (BPAR). Secondary outcomes were graft loss, infections and death. Data was analyzed by multi-variable cox hazard analysis, and competing risks by STATA16
Of total 74 LDKT cases, 31 were ATLG and 43 were IL-2RB. The first and last transplant was done on 22 Dec 2020 and 30 Dec 2021 respectively with 1-year follow-up. The median(IQR) age of recipients and donors was 28(24-33) and 52(46-56) years respectively. In cox analysis, there was no difference in terms of BPAR (HR: 0.12, 95% CI: 0.009-1.5, p-value = 0.1) and infections (HR: 0.43 95% CI: 0.12-1.44, p-value = 0.172). However, allograft biopsies were less often performed in IL-2RB compared to ATLG (HR:0.08, 95% CI: 0.01-0.49, p-value =0.006). There was no statistical difference for serum creatinine between two groups at various follow-ups. There was one mortality and graft loss in the study.
Outcomes of ATLG and IL2-RB are comparable in moderate risk LRTR in our study.
