Provider and Peer Support Intervention to Improve ART Adherence among Kenyan Men

描述（由申请人提供）：尽管男男性行为者（MSM）在全球范围内感染艾滋病毒的风险非常高，但这一群体直到最近才成为撒哈拉以南非洲国家艾滋病毒/艾滋病计划的重要重点。虽然很明显，抗逆转录病毒疗法（ART）可以降低艾滋病相关的发病率和死亡率，并防止艾滋病毒感染的男男性行为者的性传播，但人们对非洲男男性行为者的抗逆转录病毒治疗依从性和护理障碍知之甚少。自2005年以来，我们一直与肯尼亚海岸从事性工作的男男性接触者合作，发现这一群体在艾滋病毒治疗参与、ART依从性和临床结果方面存在显著差异，至少部分原因是耻辱和社会孤立。让机器人提供者和同行参与干预，以支持MSM，因为他们启动ART，结合定期的消息传递，以促进依从性，是解决这一治疗差距的创新策略。在这个R34应用程序，准备响应PAR-11-278“发现，开发和测试新的干预措施，以推进艾滋病毒的预防和护理，”我们提出了一个为期3年的发展项目，设计和试点测试文化上适当的和可推广的抗逆转录病毒依从性干预非洲男男性行为者。该项目是华盛顿大学、肯尼亚医学研究所、牛津大学和布朗大学经验丰富的研究人员之间的多学科合作，基于对肯尼亚男男性接触者进行研究的7年经验，支持了该提案的意义和创新。我们的具体目标是：（1）进行定性研究，包括深入访谈和焦点小组与HIV-1血清阳性的男男性行为者，治疗经验丰富的同行，以及他们的供应商，以确定共同的障碍和可能的促进ART依从性;（2）设计和现场测试理论驱动的干预措施，为男男性行为者结合供应商和同行的支持，以鼓励参与护理，建立信任，并提供定期的依从性信息;以及（3）对60名MSM参与者实施一项试点随机对照试验（RCT），以比较多组分干预与标准治疗。我们将为干预措施开发培训模块和支持材料，包括以患者为中心的护理，动机性访谈，同伴支持和依从性信息，以适应我们定性研究的具体结果。拟议的研究与NIH艾滋病研究办公室关于减少艾滋病毒相关差异和改善艾滋病毒感染者疾病结局的优先事项相一致，也与2011年医学研究所关于女同性恋、男同性恋、双性恋、和跨性别人士实施旨在促进知识和了解LGBT健康的研究议程。这项形成性R34研究的结果将提供有关可行性、可接受性、耐受性、安全性和初步效应量的数据，或R 01建议，以在一项充分有效的RCT中测试这种干预措施及其组成部分，包括来自撒哈拉以南非洲多个研究中心的更大、更多样化的MSM样本。

DESCRIPTION (provided by applicant): Although men who have sex with men (MSM) are at very high risk for HIV globally, this group has only recently become an important focus of national HIV/AIDS programs in sub-Saharan Africa. While it is clear that antiretroviral therapy (ART) can reduce AIDS-related morbidity and mortality and prevent sexual transmission from HIV-infected MSM, little is known about antiretroviral adherence and barriers to care among African MSM. We have worked with MSM involved in sex work on the Kenyan coast since 2005, and have found significant disparities in HIV treatment engagement, ART adherence, and clinical outcomes in this group, due at least in part to stigma and social isolation. Involving bot providers and peers in an intervention to support MSM as they initiate ART, combined with regular messaging to promote adherence, is an innovative strategy to address this treatment gap. In this R34 application, prepared in response to PAR-11-278 "Discovery, Development, and Testing of Novel Interventions to Advance HIV Prevention and Care," we propose a 3-year developmental project to design and pilot test a culturally appropriate and generalizable antiretroviral adherence intervention for African MSM. The project is a multidisciplinary collaboration among experienced investigators at the University of Washington, Kenya Medical Research Institute, University of Oxford, and Brown University, based on a foundation of 7 years' experience conducting research with Kenyan MSM that underpins the significance and innovation of this proposal. Our specific aims are to: (1) conduct qualitative research including in-depth interviews and focus groups with HIV-1-seropositive MSM, treatment-experienced peers, and their providers to identify common barriers and likely facilitators of ART adherence; (2) design and field test a theoretically driven intervention for MSM combining provider and peer support to encourage engagement in care, build trust, and deliver regular adherence messaging; and (3) implement a pilot randomized controlled trial (RCT) of the resulting multi-component intervention versus standard care with 60 MSM participants. We will develop training modules and supporting materials for an intervention including patient-centered care, motivational interviewing, peer support, and adherence messaging adapted to the specific findings of our qualitative study. The proposed research is consistent with and responds to priorities set by the NIH Office of AIDS Research on reducing HIV-related disparities and improving disease outcomes for HIV-infected individuals, and is also consistent with the recommendation set forth in the 2011 Institute of Medicine report on The Health of Lesbian, Gay, Bisexual, and Transgender People to implement a research agenda designed to advance knowledge and understanding of LGBT health. Findings from this formative R34 study will provide data on the feasibility, acceptability, tolerability, safety, and preliminary effect sizes or an R01 proposal to test this intervention and its components in a fully powered RCT including a larger, more diverse sample of MSM from multiple sites in sub-Saharan Africa.
