DESCRIPTION (provided by applicant): HCV-related liver disease is a leading cause of mortality among HIV-infected individuals in the U.S. Current therapy for HCV infection has limited efficacy, but the first HCV protease inhibitors were recently approved by the FDA and have substantially improved treatment outcomes. Many HCV-infected individuals, however, are not aware that they are infected. Further, as a result of limited treatment uptake and high rates of loss to follow- up, few HIV/HCV co-infected patients ever initiate HCV therapy. Recognizing the public health challenge represented by HCV, the Institute of Medicine and American Association for the Study of Liver Diseases have called for studies to identify the best strategies for HCV screening and care delivery. We propose to build a mathematical model of HIV/HCV co-infection to generate urgently-needed evidence that will inform screening and treatment guidelines and improve patient outcomes. The three specific aims are: 1. To develop and validate a Monte Carlo simulation model of HIV/HCV co-infection that includes HCV and HIV screening, linkage to and retention in care, and treatment. 2. To use the model to conduct and disseminate a series of analyses that will develop the evidence needed to inform clinical guidelines for identifying and managing HIV/HCV co-infection in the era of directly acting antiviral therapies against HCV. 3. To conduct policy analyses that will develop priorities for improving access to HCV treatment and project the budgetary impact of widely-available directly acting therapies against HCV. The proposed specific aims will answer critical questions about the best strategies for identifying and treating HCV and HIV/HCV co-infection. The project will develop a durable platform poised to be the premier tool for rapidly conducting rigorous analyses of the comparative-effectiveness and cost-effectiveness of strategies for improving HCV and HIV/HCV care in the new era of effective HCV therapy.

描述（由申请人提供）：HCV相关肝脏疾病是美国hiv感染者死亡的主要原因。目前HCV感染的治疗效果有限，但首批HCV蛋白酶抑制剂最近获得FDA批准，并显著改善了治疗结果。然而，许多丙型肝炎病毒感染者并不知道自己被感染了。此外，由于有限的治疗接受率和随访失败率高，很少有HIV/HCV合并感染的患者开始接受HCV治疗。认识到丙型肝炎病毒所代表的公共卫生挑战，医学研究所和美国肝病研究协会呼吁开展研究，以确定丙型肝炎病毒筛查和护理提供的最佳策略。我们建议建立HIV/HCV合并感染的数学模型，以产生迫切需要的证据，为筛查和治疗指南提供信息，并改善患者预后。三个具体目标是：1。开发和验证艾滋病毒/丙型肝炎合并感染的蒙特卡罗模拟模型，包括丙型肝炎和艾滋病毒筛查、与护理和治疗的联系和保留。2. 利用该模型开展和传播一系列分析，为在直接作用于丙型肝炎病毒的抗病毒治疗时代识别和管理艾滋病毒/丙型肝炎病毒合并感染的临床指南提供所需的证据。3. 开展政策分析，制定改善丙肝病毒治疗可及性的优先事项，并预测广泛可用的丙肝病毒直接作用疗法对预算的影响。提出的具体目标将回答关于确定和治疗丙型肝炎病毒和艾滋病毒/丙型肝炎病毒合并感染的最佳策略的关键问题。该项目将开发一个持久的平台，成为在有效治疗丙型肝炎病毒的新时代，快速对改善丙型肝炎病毒和艾滋病毒/丙型肝炎病毒护理策略的相对有效性和成本效益进行严格分析的首要工具。
