Role of induction therapy in low immunological risk–kidney transplant recipients: A mate‐kidney analysis

Le résumé fourni par la source

We aimed to evaluate the impact of induction on outcomes in low-immunological risk kidney transplant recipients (KTRs) using a mate-kidney model. Using OPTN/UNOS database, we identified three groups of low-immunological risk KTRs (first transplant, panel reactive antibody <20%, human leukocyte antigen mismatches ≤3) with each group containing recipients of mate-kidneys from same donor and differed by induction received: group 1: no induction vs interleukin-2 receptor antibody (IL2RA) induction; group 2: no induction vs depleting antibody induction; group 3: IL2RA vs depleting antibody induction. Outcomes were compared between mate-kidney recipients in each group in an adjusted model. Total of 1034 mate-kidney recipients were identified: group 1, n = 192; group 2, n = 362 and group 3, n = 480. Adjusted risk for DGF was higher (OR 1.89, 95% CI 1.09-3.25,.P = 0.02) and one-year acute rejection trended lower (OR 0.53, 95% CI 0.25-1.11, P = 0.09) among depleting antibody induced patients in group 2. Adjusted five-year graft survivals were similar between mate-kidney recipients in all three groups. Adjusted patient death risk was significantly lower in depleting antibody induced patients in group 2 (HR 0.48, 95% CI 0.26-0.88, P = 0.02) and trended lower in IL2RA induced patient in group 1 (HR 0.32, 95% CI 0.10-1.01, P = 0.05). Perioperative antibody induction was associated with lower patient death risk in low-immunologic risk KTRs.
