概括
使用70岁及以上的捐赠者进行肝移植的结果随着时间的推移而有所改善,特别是在低风险接受者中. 这些老年捐赠者提供了一个可行的选择,以增加移植的可用性,风险分数有助于选择.

背景情况:
- 肝脏移植的需求与捐赠器官的可用性之间存在很大的差距.
- 利用年长的捐赠者 (≥70岁) 是增加可行的肝移植供应的潜在策略.
- 关于使用70岁及以上的供体进行肝移植的结果,国家数据有限.
研究的目的:
- 用70岁及以上的已故捐赠者来调查肝移植的结果.
- 评估捐赠者年龄对肝移植中移植存活率的影响.
- 评估风险评分系统在预测老年捐赠肝脏移植的结果时的有用性.
主要方法:
- 美国移植受体科学注册数据库 (1988-2021) 的分析.
- 计算每位患者的风险平衡 (BAR) 和肝移植后生存结果 (SOFT) 评分.
- 用立方脊柱曲线对捐赠者年龄的范围进行移植存活的评估.
主要成果:
- 分析了超过148,000例肝移植,其中3.6%来自≥70年捐赠者.
- 随着时间的推移,≥70岁的捐赠者接受者的移植存活率显著改善,达到9.6年的中位数 (2010-2019).
- 老年捐赠者 (≥70岁) 在移植到老年接受者 (≥70岁) 时,表现出与年轻捐赠者 (<70岁) 相似的结果,特别是在低风险病例中 (SOFT评分<5).
结论:
- 70岁及以上的已故捐赠者可以安全考虑进行肝移植,特别是低风险接受者.
- BAR和SOFT分数是指导扩大使用老年捐赠肝移植的有价值的工具.
- 在2010年至2019年间进行的肝移植中,增加供体年龄与更差的移植存活率无关.
