JAMA Intern Med:急性肾损伤后使用ACEI或ARB利弊皆有

2019-01-06 王淳 环球医学

急性肾损伤(AKI)患者死亡的长期风险会增加。改善AKI患者长期结局的有效策略未知。2018年12月,加拿大学者发表在《JAMA Intern Med》的一项研究,考察了血管紧张素转换酶抑制剂(ACEI)或血管紧张素受体阻滞剂(ARB)与AKI后结局的相关性。

急性肾损伤(AKI)患者死亡的长期风险会增加。改善AKI患者长期结局的有效策略未知。2018年12月,加拿大学者发表在《JAMA Intern Med》的一项研究,考察了血管紧张素转换酶抑制剂(ACEI)或血管紧张素受体阻滞剂(ARB)与AKI后结局的相关性。

目的:旨在评估出院后使用ACEI或ARB是否与AKI患者更好的结局相关。

设计、地点和参与者:这项回顾性队列研究使用了阿尔伯塔肾脏疾病网络人群数据库的数据,旨在评估加拿大阿尔伯塔2008年7月1日~2015年3月31日住院期间AKI发病的46253名18岁或以上的成年患者。所有存活到出院的患者都最少随访2年。

暴露:出院后6个月内使用ACEI或ARB。

主要结局和测量指标:首要结局为死亡率;次要结局包括肾病原因住院、终末期肾病(ESRD)、ESRD或血清肌酐浓度持续加倍的复合结局。AKI的定义为住院前和住院期间血清肌酐浓度峰值的差值增加50%。倾向得分用于创建出院后6个月内具有和不具有ACEI或ARB处方的患者的配对队列。

结果:研究评估了46253名成人(平均(SD)年龄68.6(16.4)岁,男性24436人(52.8%))。出院后6个月内,22193人(48.0%)处方了ACEI或ARB。调整了合并症、住院前使用ACEI或ARB、人口统计学、基线肾功能、与此次住院相关的其他因素、既往医疗服务后,ACEI或ARB的使用与AKI患者2年后较低的死亡率相关(调整风险比(HR),0.85;95% CI,0.81~0.89)。然而,接受ACEI或ARB的患者具有较高的肾脏原因住院风险(调整HR,1.28;95% CI,1.12~1.46)。ACEI或ARB使用与ESRD进展之间无相关性。

结论和意义:AKI患者中,ACEI或ARB治疗与较低的死亡率相关,但与较高的肾脏原因住院风险相关。这些结果提示了AKI后使用ACEI或ARB的潜在获益,但是需要谨慎监测肾脏特异性并发症。
