Pediatric kidney donation after cardiac death is an underutilized donor source because of ethical concerns and limited knowledge of the outcome after transplantation. The purpose of this study was to report the Dutch experience of kidney transplantation using pediatric donation after cardiac death.
Observational cohort study of a series of consecutive kidney transplantations from pediatric donation after cardiac death from January 1995 to July 2006.
Kidneys were procured in seven Dutch procurement areas.
Recipients of kidneys from donors after cardiac death aged 2 to 17 yrs.
Prospectively collected data from the Dutch Organ Transplant Registry were analyzed. Donor, graft, and recipient characteristics of all pediatric donations after cardiac death kidney transplantations were documented. Recipients were followed-up for glomerular filtration rate, graft, and patient survival. Eighty-eight patients were transplanted with 90 pediatric donation-after-cardiac-death kidneys, which was 31% of the total number of transplanted pediatric donor kidneys. In 77% of recipients, organs were procured from controlled donors, after withdrawal of supportive treatment. Of all donors, 9% were younger than age 6 yrs. Two patients received their graft preemptively. In the others, the incidence of immediate function, delayed graft function, and primary nonfunction were 49%, 44%, and 7%, respectively. Warm ischemia time > or =25 mins was associated with primary nonfunction. Overall graft and patient survival 5 yrs after transplantation were 80% and 88%, respectively. Graft survival after immediate function and delayed graft function was not different.
Kidneys from pediatric donation after cardiac death are suitable for transplantation and may substantially expand the donor pool with good transplant outcome.
由于伦理问题和对移植后结果的了解有限,小儿心死亡后供肾的利用率较低。本研究旨在报告荷兰使用小儿心死亡后供肾进行肾移植的经验。
对 1995 年 1 月至 2006 年 7 月期间连续进行的小儿心死亡后肾移植的系列病例进行观察性队列研究。
在 7 个荷兰采购区获取供肾。
年龄在 2 至 17 岁之间接受心死亡后供者肾移植的受者。
分析了荷兰器官移植登记处的前瞻性收集数据。记录了所有小儿心死亡后肾移植供者、移植物和受者的特征。对受者进行肾小球滤过率、移植物和患者存活率随访。88 例患者接受了 90 例小儿心死亡后供肾移植,占所有小儿供肾移植的 31%。在 77%的受者中,器官是在停止支持治疗后从受控供者中获取的。所有供者中,9%的年龄小于 6 岁。2 例患者接受了预先移植。在其余患者中,立即功能、延迟功能和原发性无功能的发生率分别为 49%、44%和 7%。热缺血时间≥25 分钟与原发性无功能相关。移植后 5 年的总体移植物和患者存活率分别为 80%和 88%。立即功能和延迟功能后的移植物存活率无差异。
小儿心死亡后供肾适合移植,可以显著扩大供体库,获得良好的移植效果。
