简介(由申请人提供):徐博士是世界上为数不多的在HIV方面有广泛研究和临床经验的心脏病专家之一,他在过去的十年里致力于HIV背景下的心血管疾病研究。她职业生涯的最初部分是1)在旧金山总医院(SFGH)建立HIV心脏病学诊所,2)在SFGH心脏病学部门发展开展POR研究的基础设施,其中包括开发用于临床研究的血管实验室,以及3)开展评估HIV感染和心血管疾病(CVD)潜在机制的研究。她的研究结果表明,1)HIV感染与CVD独立相关,与传统的危险因素或HIV药物无关;2)在有效治疗HIV感染的情况下,慢性炎症是增加CV风险的基础;3)确定降低HIV相关炎症和CV风险的治疗方法。在她的5年K24奖提案中,她计划增加她在HIV感染、HIV相关炎症和心血管疾病领域指导初级研究人员的时间,以帮助他们在未来成为成功的独立研究人员。她的K24提案将扩展她目前的R01资助的研究,通过研究HIV相关动脉粥样硬化在治疗HIV感染的背景下的潜在机制,有以下两个具体目标:1)通过颈动脉内膜-中膜厚度(IMT)评估单核细胞/巨噬细胞激活在动脉粥样硬化进展中的作用,通过肱动脉血流介导的血管扩张(FMD)评估内皮功能障碍,以及在有效治疗的HIV感染者中微血管疾病(通过峰值充血速度测量)。在接受有效治疗的艾滋病毒感染者中发生微血管疾病。K24提案将提供受试者访问、血管成像、临床和实验室数据,以支持指导hiv相关心血管疾病领域以患者为导向的转化研究的新研究者。
英文摘要
DESCRIPTION (provided by applicant): Dr. Hsue is one of the few cardiologists in the world with both extensive research and clinical expertise in HIV and has devoted the last ten years studying cardiovascular disease in the setting of HIV. The initial part of her career was spent 1) establishing a HIV Cardiology Clinic at San Francisco General Hospital (SFGH), 2) developing the infrastructure to perform POR research in the Cardiology Division at SFGH which has included development of a vascular laboratory for clinical research, and 3) performing studies that evaluate the mechanisms underlying HIV infection and cardiovascular disease (CVD). The findings from her work have shown that 1) HIV infection is independently associated with CVD, independent of traditional risk factors or HIV medication, and 2) chronic inflammation in the setting of effectively treated HIV infection underlies this increased CV risk, and 3) identifying therapies to reduce HIV-associated inflammation and CV risk. For her 5 year K24 award proposal, she plans to increase her time spent mentoring junior investigators in the fields of HIV infection, HIV-associated inflammation, and cardiovascular disease for the purpose of helping them to become successful independent researchers in the future. Her K24 proposal will extend upon her current R01 funded investigations by studying the underlying mechanism of HIV-associated atherosclerosis in the setting of treated HIV infection with the following two Specific Aims: 1) To characterize the role of monocyte/macrophage activation in atherosclerotic progression as assessed by carotid artery intima-media thickness (IMT), endothelial dysfunction as assessed by flow-mediated vasodilation of the brachial artery (FMD), and microvascular disease (measured by peak hyperemic velocity) in effectively treated HIV-infected individuals 2) To determine the role of HIV reservoir on atherosclerotic progression, endothelial function, and microvascular disease in effectively treated HIV-infected individuals. The K24 proposal will provide subject visits, vascular imaging, and clinical and laboratory data to support mentoring new investigators in patient-oriented translational research in the field of HIV-related cardiovascular disease.
