在日本,采用口服DAA药物治疗HCV基因1b型患者,由于减少HCC和失代偿性肝硬化的发生,而显著地增加了直接和间接经济效益

研究背景:肝细胞癌是HBV和HCV感染导致的严重并发症之一。HCV患者获得可持续病毒学应答(SVR)与肝硬化、肝癌和相关死亡以及相关花费的减少相关。日本高龄的HCV患者患HCC的机率较高。本研究旨在采用决策分析马尔科夫模型分析通过减少HCC和失代偿性肝硬化,获得的经济效益。

研究方法:本研究纳入10000例HCV基因1b型患者。采用混合决策树和马尔可夫状态转换模型,捕捉HCV在生命周期内的自然历史。治疗方案被批准为采用全口服直接作用的抗病毒药物(DAAs)和不治疗方案。治疗效果基于临床试验、转移率和费用。对采用直接抗病毒治疗与不治疗的HCC、失代偿肝硬化(DCC)和质量调整生命年(QALYs)的病例进行了预测。质量调整生命年(QALYs)通过愿意支付4到6百万日元被货币化。通过增加在并发症上的预计费用,来计算节省的治疗费用。

研究结果:分析模型表明,相比不治疗的策略,采用DAA治疗减少了2057例HCC和1478例失代偿性肝硬化的发生;为每个患者(ppt)节省了850,446.73、338,229.90日元。除此之外,治疗使每位患者额外获得2.64 QALYs。与治疗导致QALY改善相关的间接的经济效益,分别为10,576,000日元、13,220,000日元和15,864,000日元/每位患者(愿意支付400万日元、500万日元和600万日元的阈值)。在不同的支付阈值上,采用DAAs( vs不接受治疗)治疗节省的费用分别为7526,372.63、10,170,372.63和12,814,372.63日元。

研究结论:在日本,采用口服DAA药物治疗HCV基因1b型患者,由于减少HCC和失代偿性肝硬化的发生,而显著地增加了直接和间接经济效益。
