Little has changed in donor management and liver utilization rates in Brazil over the last decade. With a growing demand for liver donations, organ waste is an important obstacle toward better patient care. The study of discarded donors helps to shed light on the possibilities of increasing organ usage, including by using extended criteria donors.
We retrospectively analyzed all discarded liver donors in a high-volume Brazilian transplant center from January 2015 to December 2018. Pertinent clinical and laboratorial data were collected from the donors' electronic health records.
In our study period, there were 248 liver harvests, of which 67 (27.0%) were discarded. Most discarded donors were male (65.7%). More than three-quarters of donors were Caucasian (79.1%). Median donor body mass index was 26.27 kg/m, and most discarded donors presented no comorbidities. Donor liver injury tests were abnormal in 56 (83.5%) out of 67 discarded donors. Forty-three (64.1%) donors presented elevated transaminases. Alanine aminotransferase levels were elevated in 35 (52.2%) discarded donors, with a median value of 38 U/L. Half of all discarded livers were due to graft-related issues. Twenty-eight organs (41.79%) presented external pathologic alterations. Organ refusal due to donor clinical and laboratorial condition was reported in 24 cases.
It is clear there is a considerable issue of organ waste in Brazil, with the subjective judgment of graft quality and inadequate interpretation of donor's laboratorial exams leading to excessive denial of organs that could be fitted into extended criteria for donation.
在过去十年中,巴西的供体管理和肝脏利用率变化不大。随着肝脏捐赠需求的不断增加,器官浪费成为改善患者护理的一个重要障碍。对废弃供体的研究有助于阐明提高器官利用率的可能性,包括使用扩大标准供体。
我们回顾性分析了2015年1月至2018年12月期间巴西一家大型移植中心所有废弃的肝脏供体。从供体的电子健康记录中收集相关的临床和实验室数据。
在我们的研究期间,共进行了248例肝脏获取手术,其中67例(27.0%)被废弃。大多数废弃供体为男性(65.7%)。超过四分之三的供体为白种人(79.1%)。供体体重指数中位数为26.27kg/m,大多数废弃供体无合并症。67例废弃供体中,56例(83.5%)的供体肝脏损伤检查异常。43例(64.1%)供体转氨酶升高。35例(52.2%)废弃供体的丙氨酸转氨酶水平升高,中位数为38U/L。所有废弃肝脏中有一半是由于移植物相关问题。28个器官(41.79%)存在外部病理改变。24例报告因供体临床和实验室状况而拒绝器官。
显然,巴西存在相当严重的器官浪费问题,对移植物质量的主观判断以及对供体实验室检查的解读不足导致过多可符合扩大捐赠标准的器官被拒绝。
