AP&T: 直接作用的抗病毒药物治疗丙型肝炎可降低静脉曲张破裂出血的风险

2020-02-16 不详 MedSci原创

持续的病毒学应答(SVR)对于曲张静脉出血风险的长期益处尚不清楚,因此,本项研究的目的是评估DAA诱发的SVR与治疗后曲张静脉出血之间的关联

背景
持续的病毒学应答(SVR)对于曲张静脉出血风险的长期益处尚不清楚,因此,本项研究的目的是评估DAA诱发的SVR与治疗后曲张静脉出血之间的关联

方法
研究人员纳入了从2013年至2015年在美国退伍军人事务医疗系统中启动仅使用DAA的抗病毒治疗的患者。研究人员对患者进行了随访,直到2019年1月1日,主要观察结局是食管静脉曲张破裂出血。使用多变量Cox比例风险回归来评估SVR与静脉曲张破裂出血之间的关联,并调整潜在的混杂因素。

结果
在33582例接受DAA治疗的患者中,有549例(占1.6%)在治疗后出现静脉曲张破裂出血(平均随访时间为3.1年)。与无SVR相比,所有SVR患者中SVR与曲张静脉出血的发生率显着降低(每100患者年0.46 VS 1.26,调整后的危险比[AHR] 0.66,95%CI 0.52-0.83)。治疗性肝硬化(每100病人年1.55比2.96,AHR 0.73,95%CI 0.57-0.93)和无治疗前肝硬化的患者(每100病人年0.07 vs 0.29,AHR 0.33,95%CI 0.17-0.65)。在没有出血前静脉曲张(每100病人年,3.5 vs 4.9)或以前诊断为出血前静脉曲张(每100病人年,12.9 vs 16.4)的患者中,获得SVR的患者治疗后曲张静脉出血的风险较低。

结论
在有或没有治疗前肝硬化的患者中,DAA诱导的SVR与静脉曲张破裂出血的低风险独立相关。
