Hepatology:预测肝硬化患者发生肝性脑病的因素!

2017-11-02 MedSci MedSci原创

超过40%的肝硬化患者会发展为肝性脑病(HE)。研究表明,HE与患者的生存下降、跌倒、机动车辆事故以及住院频率增加密切相关。近期,一项发表在杂志Hepatology上的研究旨在开发一种能够对发展为HE患者的风险分层的工具。此项研究为基于人群队列的所有肝硬化患者,包括来自密歇根州、印第安纳州和俄亥俄州的退伍军人管理局(1/1 / 2005-12 / 31/10),所有受试人群在基线时均无HE(N =

超过40%的肝硬化患者会发展为肝性脑病(HE)。研究表明,HE与患者的生存下降、跌倒、机动车辆事故以及住院频率增加密切相关。


近期,一项发表在杂志Hepatology上的研究旨在开发一种能够对发展为HE患者的风险分层的工具。

此项研究为基于人群队列的所有肝硬化患者,包括来自密歇根州、印第安纳州和俄亥俄州的退伍军人管理局(1/1 / 2005-12 / 31/10),所有受试人群在基线时均无HE(N = 1,979)。主要研究结果是HE的发展。使用基线和纵向数据(每年更新的参数)构建风险评分,并使用自举验证。
此项研究结果显示:人群队列的平均年龄58.0±8.3岁,丙型肝炎占36%,腹水占17%。在基线时使用阿片类药物、苯二氮卓类药物、他汀类药物和非选择性β-受体阻滞剂分别占24%、13%、17%和12%。

总体而言,5年内共有863(43.7%)人发展为HE。在多变量模型中,HE的危险因素(HR,95%CI)包括高胆红素(1.07,1.05〜1.09)和非选择性β-阻滞剂的使用(1.34,1.09-1.64),而高白蛋白(0.54,0.48-0.59)和他汀类药物使用(0.80,0.65-0.98)具有保护作用。

其他临床因素,包括阿片类和苯二氮卓类药物的使用并不具有预测性。在基线和纵向模型中使用4个重要变量的AUROC分别为0.68(0.66-0.70)和0.73(0.71-0.75)。纵向模型的得分≤0则1年的HE风险为6%,而得分> 20则1年的HE风险为38%。

此项研究结果表明:肝硬化的患者可以通过简单的风险评分进行HE的分层。此项研究数据还突出了他汀类药物在减少肝硬化并发症(包括HE)中的作用。
