Hepatitis C virus (HCV) infection is a major cause of cirrhosis and liver cancer, and many developing countries report intermediate-to-high prevalence. However, the economic impact of screening and treatment for HCV in high prevalence countries has not been well studied. Thus, we examined the cost-effectiveness of screening and treatment for HCV infection for asymptomatic, average-risk adults using a Markov decision analytic model. In our model, we collected age-specific prevalence, disease progression rates for Egyptians and local cost estimates in Egypt, which has the highest prevalence of HCV infection (15%) in the world. We estimated the incremental cost-effectiveness ratio and conducted sensitivity analyses to determine how cost-effective HCV screening and treatment might be in other developing countries with high and intermediate prevalence. In Egypt, implementing a screening programme using triple-therapy treatment (sofosbuvir with pegylated interferon and ribavirin) was dominant compared with no screening because it would have lower total costs and improve health outcomes. HCV screening and treatment would also be cost-effective in global settings with intermediate costs of drug treatment ($8000) and a higher sustained viral response rate (70-80%).
丙型肝炎病毒(HCV)感染是肝硬化和肝癌的主要病因,许多发展中国家报告其感染率处于中高水平。然而,在高感染率国家,HCV筛查和治疗的经济影响尚未得到充分研究。因此,我们使用马尔可夫决策分析模型,研究了对无症状、平均风险成年人进行HCV感染筛查和治疗的成本效益。在我们的模型中,我们收集了埃及人的年龄特异性感染率、疾病进展率以及埃及的当地成本估计数据,埃及是世界上HCV感染率最高(约15%)的国家。我们估计了增量成本效益比,并进行了敏感性分析,以确定在其他高感染率和中等感染率的发展中国家,HCV筛查和治疗的成本效益如何。在埃及,与不进行筛查相比,实施使用三联疗法(索磷布韦联合聚乙二醇干扰素和利巴韦林)的筛查计划具有优势,因为它将降低总成本并改善健康结果。在药物治疗成本中等(约8000美元)且持续病毒学应答率较高(70 - 80%)的全球环境中,HCV筛查和治疗也具有成本效益。
