概括
携带人类免疫缺陷病毒 (HIV) 的捐赠者的器官可以安全地用于HIV阳性接受者的心脏移植 (HTx). 早期结果显示,艾滋病毒阳性和艾滋病毒阴性捐赠者群体的生存率,排斥率和感染率相似.
科学领域:
- 移植免疫学 移植免疫学
- 传染性疾病 传染性疾病
- 心脏病学 心脏病学
背景情况:
- 固体器官移植正在推进,人们越来越感兴趣使用来自人类免疫缺陷病毒 (HIV) 阳性捐赠者的器官用于HIV阳性接受者.
- 以前的限制和道德考虑限制了艾滋病毒阳性个体的器官共享.
研究的目的:
- 为了比较心脏移植 (HTx) 的早期结果,HIV阳性接受者使用来自HIV阳性或HIV阴性捐赠者的器官.
- 评估利用HIV阳性捐献器官在HIV阳性接受者中的安全性和可行性.
主要方法:
- 进行了一项单一中心的观察性研究.
- 10名艾滋病毒阳性接受者接受了HTx,其中4人从艾滋病毒阳性捐赠者获得器官,6人来自艾滋病毒阴性捐赠者.
- 包括存活率,排斥率,感染率,艾滋病毒抑制率和来自供体的无细胞DNA在内的结果被监测了移植后的6个月.
主要成果:
- 这两组在6个月后都显示出100%的生存率 (p=1.00).
- 在两组之间,每个患者排斥 (p=0.69) 或感染 (p=0.25) 的次数没有显著差异.
- 在两组接受者的100% (p=1.00) 实现了完全的艾滋病毒抑制 (病毒载量<25副本/毫升或不可检测).
- 捐赠者获得的细胞自由DNA水平在两组之间是可比的 (p=0.11).
结论:
- 早期的结果表明,来自艾滋病毒感染者的器官可以安全地移植到艾滋病毒阳性接受者身上.
- 在HIV阳性接受者中使用HIV阳性供体器官用于HTx似乎是可行的,并且不会影响短期结果.
- 这种方法可能会扩大这群人群中心脏移植的供体库.

Kidney Transplant I: Introduction
343
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...

Tissue transplantation is a significant medical procedure involving the transfer of cells, tissues, or organs from a donor to a recipient, with the primary aim of restoring lost functions. This procedure is crucial in treating a broad spectrum of diseases, including kidney diseases, liver failure, heart disease, and certain types of cancers.
