We aimed to determine outcomes with transplanting kidneys from deceased donors with severe acute kidney injury requiring acute renal replacement therapy (RRT).
A total of 172 recipients received a kidney from donors with acute kidney injury stage 3 (AKIN3) requiring RRT. We compared the study group to 528 recipients who received a kidney from donors with AKIN stage 3 not on RRT and 463 recipients who received < 85% Kidney Donor Profile Index (KDPI) AKIN stage 0 kidney.
The study group donors were younger compared to the 2 control groups. Despite higher DGF in the study group, the length of hospital stay and acute rejection were similar. Death censored graft survival (96% AKIN3-RRT vs. 97%AKIN3 no RRT vs. 96% KDPI < 85% AKIN0, P = 0.26) and patient survival with functioning graft at 1 year (95% across all groups, P = 0.402) were similar. The estimated glomerular filtration rate were similar across the 3 groups after first month. Interstitial fibrosis and tubular atrophy score ≥ 2 on protocol biopsy at time 0, 4 and 12 months were similar. Primary nonfunction was rare and associated with high KDPI.
Transplanting selected kidneys from deceased donors with AKIN3 requiring RRT is safe and has good outcomes.
本研究旨在评估接受需要急性肾脏替代治疗(RRT)的急性肾损伤(AKI)3 期供者肾移植的患者结局。
共有 172 例接受 RRT 的 AKI 3 期供者肾移植患者纳入研究,将其与 528 例接受 AKI 3 期非 RRT 供者肾移植患者和 463 例接受 KDPI<85%的 AKI 0 期供者肾移植患者进行比较。
研究组供者的年龄小于 2 个对照组。尽管研究组发生延迟肾功恢复(DGF)的比例较高,但住院时间和急性排斥反应的发生率相似。死亡风险校正的移植物存活率(AKIN3-RRT 组 96%,AKIN3 非 RRT 组 97%,KDPI<85%的 AKIN0 组 96%,P=0.26)和 1 年时带功能移植物的患者存活率(所有组均为 95%,P=0.402)相似。第 1 个月后,3 组的估算肾小球滤过率相似。0、4 和 12 个月时的方案活检中间质纤维化和肾小管萎缩评分≥2 的比例相似。原发无功能罕见,与高 KDPI 相关。
移植需要 RRT 的 AKI 3 期供者的肾脏是安全的,且具有良好的结局。
