概括
在儿童中,ABO不兼容的心脏移植 (HT) 提供了与ABO兼容的HT可比的结果,无论移植中心的体积如何. 2016年的政策变化没有影响这些儿科患者的等待名单死亡率.
科学领域:
- 儿童心脏病学 儿童心脏病学
- 移植免疫学 移植免疫学
- 器官移植政策 器官移植政策
背景情况:
- 对于面临供体短缺的儿科患者来说,ABO-I心脏移植 (HT) 非常重要.
- 尽管结果相似,但ABO-I HT并没有被普遍采用.
- 本研究分析了ABO-I HT趋势和结果,重点关注2016年联合器官共享网络 (UNOS) 政策变化.
研究的目的:
- 为儿童提供ABO不兼容心脏移植的当代分析.
- 评估2016年UNOS政策变化对ABO-I HT结果的影响.
- 评估儿童ABO-I HT中中心体积和生存率之间的关系.
主要方法:
- 对器官采购和移植网络数据库的回顾性分析.
- 在2016年UNOS政策变更中定义的两个时代接受HT的儿科患者 (≤2岁) 接受了检查.
- 主要结局:移植后的存活率;次要结局:等候名单死亡率,中心体积与存活率的关系,以及术后并发症.
主要成果:
- 共有2,770名儿童接受了HT,其中493人 (18%) 是ABO-I接受者.
- 在不同时期的ABO-I合格候选人等候名单死亡率没有显著差异 (HR 0.70,P=.07).
- 在ABO-I和ABO-兼容 (ABO-C) 队列中,一年和五年生存率相似,并且在高体积和非高体积中心之间没有观察到ABO-I接受者的生存率差异.
结论:
- 不兼容ABO的心脏移植提供了与ABO兼容心脏移植相比的结果.
- 中心体积不会影响ABO-I HT接受者的生存率.
- 2016年UNOS的政策没有影响这个儿科群体的等候名单死亡率,支持ABO-I HT作为护理标准.

Kidney Transplant I: Introduction
310
A kidney transplant is a surgical approach that involves replacing a non-functioning kidney with a healthy one from a donor. This procedure is often a treatment option for end-stage renal disease (ESRD) patients. The method requires careful recipient selection, including evaluating various medical and psychosocial factors. These criteria vary between transplant centers but generally include assessments of the patient's overall health, adherence to medical recommendations, and lifestyle...
