ABO-identical blood group matching has no survival benefit for AB heart transplant recipients.

摘要: Background Although identical blood group matching is preferred, it uncertain if this results in improved survival and, so, how large the benefits are. Earlier studies have yielded conflicting and are mostly based on single-center cohorts with few long-term results. Recipients AB of particular interest regarding nonidentical because they may receive organs from all groups. We wanted to test hypothesis that ABO-identical superior recipients AB. Methods used data International Society for Heart Lung Transplantation registry match a cohort heart donors transplant Cox regression analysis was assess influence outcome after transplantation. All-cause cumulative mortality during study period primary end point. Results The material consisted 3,589 adult patients who had received transplants, representing 18,085 patient-years. No significant difference identical, as opposed compatible, ABO found In subgroup analysis, we younger ( p  = 0.02). Conclusions no benefit transplanted organs. than 55 years age, our suggests an organ donor O.
