BACKGROUND: Individualizing induction therapy based on immunological risk is crucial for optimizing outcomes in kidney transplantation.
METHODS: A retrospective analysis included 157 first live-donor non-sensitized kidney transplant recipients (KTRs). Within this cohort, 96 individuals exhibited low human leukocyte antigen (HLA) matching (5-6 HLA mismatches). The low HLA match subgroup was categorized into 52 KTRs receiving basiliximab alone and 44 recipients treated with a combined single ATG dose of 1.5 mg/kg and basiliximab. The primary endpoint was early acute cellular rejection (ACR) within 6 months post-transplant while secondary outcomes encompassed infection rates, renal allograft function, length of stay (LOS) and readmissions post-transplant.
RESULTS: The incidence of early ACR was decreased for low HLA match KTRs, who received ATG-basiliximab, when compared with low HLA-matched KTRs who received basiliximab alone (9.1% vs 23.9%, P = .067). Age was a predictor for rejection, and subgroup analysis showed consistent rejection reduction across age groups. No significant differences were observed in admission for transplant LOS or in peri-operative complications, nor in infections rate including BK and cytomegalovirus viremia, allograft function and number of readmissions post-transplant up to 6 months post-transplant.
CONCLUSION: In non-sensitized first live-donor KTRs with low HLA matching, a dual ATG-basiliximab induction approach significantly reduced early ACR without compromising safety.
