RESUMO
There is no recommendation regarding the type of induction therapy to use in ABO-incompatible (ABOi) kidney transplantation. The aim of this retrospective study was to compare the outcome of ABOi living donor kidney transplant (LDKT) recipients who received either polyclonal antibodies or anti-interleukin-2 receptor (IL-2R) blockers as an induction agent. All ABOi HLA-compatible patients that received a LDKT between 03/11 and 03/18 in three French transplantation center (Paris Saint-Louis, Paris Necker, and Toulouse) were included in the study. Fifty-eight patients were given polyclonal antibodies and 39 patients received anti-IL-2R blockers. We identified by a Cox proportional hazard model the use of polyclonal antibodies as a protective factor against acute rejection (HR = 0.4, 95%CI [0-0.9], P < .05). However, pathological findings on protocol biopsies at 1 year were similar in both groups, as were patient and graft survivals, renal function, and complications. We conclude that the acute rejection rate was significantly higher in patients given anti-IL-2R blockers compared to polyclonal antibodies. However, in our series, there was no negative impact on mid-term outcome.
