GUT:肝损伤与COVID-19患者的不良临床结局独立相关

2021-03-17 MedSci原创 MedSci原创

新型冠状病毒病(COVID-19)患者常见肝功能异常,近半数患者有不同程度的肝功能不全。

      新型冠状病毒病(COVID-19)患者常见肝功能异常,近半数患者有不同程度的肝功能不全。近期病理报告显示,肝活检标本中存在中度微血管脂肪变性和轻度小叶及汇管区炎症,提示肝损伤可能是由SARS-CoV-2感染或药物性肝损伤引起的。但目前尚无临床研究分析COVID-19患者的肝功能异常是否与用药有关。考虑到SARS-CoV-2的高传染性和致病性以及肝损伤的高发病率,迫切需要分析COVID患者的肝功能,以及肝损伤在COVID-19患者中的影响。

 

 

 

      研究人员进行了一项回顾性队列研究,使用了香港的全城诊断数据库中的临床数据,通过诊断代码和/或病毒学结果确定了COVID-19,严重急性呼吸系统综合症(SARS)等患者。丙氨酸氨基转移酶(ALT)/天冬氨酸氨基转移酶(AST)升高的定义为ALT / AST≥2×正常上限(即80 U / L)。主要观察终点是入住重症监护病房(ICU)的情况以及使用有创机械通气和/或死亡的综合结果。

 

 

 

      最后一共确定了1040例COVID-19患者(平均年龄38岁,男性54%),1670例SARS患者(平均年龄44岁,男性44%)和675例其他冠状病毒感染患者(HCoV)患者(平均年龄20岁,男性57%)。ALT / AST升高发生在50.3%的SARS患者中,以及22.5%的COVID-19患者和36.0%的其他HCoV患者中。对于COVID-19患者,53例(5.1%)进入ICU,22例(2.1%)接受有创机械通气,4例(0.4%)死亡。在调整白蛋白,糖尿病和高血压等变量后,ALT / AST升高与主要终点独立相关(OR,7.92,95%CI 4.14-15.14,p <0.001)。洛匹那韦–利托那韦±利巴韦林+干扰素β的使用(aOR 1.94,95%CI 1.20-3.13,p = 0.006)和皮质类固醇(aOR 3.92,95%CI 2.14-7.16,p <0.001)的使用与ALT / AST升高独立相关。

 

 

 

      本项研究发现在COVID-19患者中,ALT / AST升高是常见现象,并且与不良的临床预后独立相关。洛匹那韦–利托那韦的使用与ALT / AST升高独立相关。
