概括
重复活体器官捐赠正在增加. 虽然对精心挑选的捐赠者来说,短期的结果似乎是安全的,但长期的安全性仍然是未知的. 接受者的结果与首次捐赠者的结果相似.
科学领域:
- 移植医学 移植医学
- 器官捐献研究 器官捐献研究
- 腎病學和肝病學.
背景情况:
- 活体器官捐赠是移植的关键组成部分.
- 已经观察到重复活体器官捐赠的趋势越来越大.
- 了解重复捐献的安全性和结果对于捐赠者咨询至关重要.
研究的目的:
- 评估重复活体器官捐献的发生率和结果.
- 为了比较重复和肝脏捐赠的安全性.
- 评估从重复活着的捐赠者捐赠后的接受者结果.
主要方法:
- 从1994年到2023年,利用了移植受体科学注册表 (SRTR) 的数据.
- 确定了220个活着的重复捐赠者和415个接受者,构建了加权的比较组.
- 分析了捐赠后6个月,1年和2年的临床和实验室结果,并比较了接受者的移植失败率.
主要成果:
- 每年重复活体捐献者的数量从2018年的5个大幅增加到2019年的25个.
- 肝脏第二捐赠者 (72.3%) 比脏第二捐赠者 (25.0%) 更常见.
- 在第二次捐赠后,非定向捐赠从30.5%增加到53.2%,短期捐赠者的并发症很低,受体移植的存活率与对照组相似.
结论:
- 重复活体捐献在特定个体的短期内似乎是安全的,但缺乏长期安全数据.
- 受体的结果,包括移植存活率,与从非重复捐赠者接受器官的人相似.
- 需要进行进一步的研究,以确定重复活体器官捐赠者的长期安全概况.
