Crit Care:急性肾损伤的新预测因素:uKIM-1

2016-09-10 Seven L 译 MedSci原创

背景:急性肾损伤(AKI)是常见的临床综合征,预后差。肾功能不全的传统标志物在预防和及时评估肾损伤严重性、以及治疗药物管理方面,具有不敏感性和非特异性。尿肾损伤分子-1(uKIM-1)是肾小管上皮细胞损伤的标志物。不同uKIM-1水平与不同程度的肾损伤相关。本研究旨在探究,uKIM-1水平能否评估AKI患者的肾功能预后。 方法:对258例患者进行了筛选,总共纳入了201例患者,随访过程中丢失

背景:急性肾损伤(AKI)是常见的临床综合征,预后差。肾功能不全的传统标志物在预防和及时评估肾损伤严重性、以及治疗药物管理方面,具有不敏感性和非特异性。尿肾损伤分子-1(uKIM-1)是肾小管上皮细胞损伤的标志物。不同uKIM-1水平与不同程度的肾损伤相关。本研究旨在探究,uKIM-1水平能否评估AKI患者的肾功能预后。

方法:对258例患者进行了筛选,总共纳入了201例患者,随访过程中丢失了17名患者;因此一共184例患者进入了研究分析。根据患者的短期(48小时)肾功能恢复情况,将其分为瞬时AKI组和肾AKI组。在定期随访的1年时间内,观察了患者肾功能的变化,对影响肾脏预后的危险因素进行了分析。

结果:肾AKI组与瞬时AKI组相比,uKIM-1水平更高。利用uKIM-1诊断肾AKI的ROC-AUC为0.691,其敏感性和特异性分别为66.3%和64.7%。肾功能恶化组与肾功能稳定组相比,uKIM-1水平更高。因此,uKIM-1水平是肾功能预后不良的预测因素。ROC曲线分析表明,基于uKIM-1预测肾AKI和AKI患者肾功能进展的AUC分别为0.680和0.703;敏感性分别为78.6%和78.4%;特异性分别为57.9%和60.8%。AKI患者uKIM-1 > 2.37 ng/mg与不良肾脏预后呈正相关。

结论:uKIM-1水平能敏感地预测AKI患者的肾功能预后,并有可能作为肾功能预后不良的早期筛查指标。
