概括

移植后急性损伤 (AKI) 的再住院显著增加了移植失败和死亡的风险. 对这些高危患者进行更密切的监测对于改善移植结果至关重要.

科学领域:

腎臟病學 (nephrology) 是一種醫學專業.
移植医学移植医学
免疫学免疫学免疫学

背景情况:

急性损伤 (AKI) 与慢性病 (CKD) 和末期病 (ESKD) 有关.
有限的研究存在于AKI对移植接受者的影响.
本研究研究了非免疫性AKI再住院和它们对长期移植结果的影响.

研究的目的:

评估与AKI相关的再住院对移植结果的影响.
评估AKI再住院和死亡审查的移植失败和全因死亡率之间的关联.

主要方法:

2010-2014年989名已故捐赠脏移植接受者的图表审查.
移植科医生对再住院原因的裁决.
用时间变化的Cox比例危险模型分析死亡审查的移植失败和全因死亡率.

主要成果:

20%的接受者经历了与AKI相关的再住院治疗.
AKI重入院与死亡审查的移植失败 (aHR 7.5) 和所有原因死亡率 (aHR 5.7) 的风险显著增加.
非AKI再住院也增加了结果风险,但比AKI相关事件的风险要小.

结论:

由于AKI移植后的再住院是不良移植结果的重要风险因素.
患有AKI再住院的患者是高危人群,需要更密切的移植后随访.
需要进一步的研究来了解和减轻AKI对移植成功的长期影响.

Kidney Structure

Kidney Structure

The kidneys are two large bean-shaped organs located in the upper abdomen. They filter the blood several times a day to remove toxins and rebalance water and electrolytes of the circulatory system via the renal veins. The kidneys receive blood directly from the heart via the renal arteries. These arteries enter the kidney at the hilum, the concave surface of the bean, where they branch and divide into smaller vessels and capillaries.
