项目摘要
PROJECT SUMMARY/ABSTRACT
With the introduction of highly-active antiretroviral therapy, people with HIV (PWH) are living longer and the
proportion of middle-older age PWH continues to rise. Advancing age is associated with an increased risk of
age-related neurogenerative diseases including Alzheimer’s disease. Both chronic HIV and aging are
associated with cognitive deficits beyond the expectations of normal aging. Comorbidities are also elevated in
older PWH which may additionally increase risk for neurodegenerative diseases. As such, it is imperative to
focus research efforts on investigating pre-determined risk factors of neurocognitive impairment among PWH.
Neurodegenerative diseases are considered to be partially inherited. In fact, the apolipoprotein e4 (APOE e4)
allele increases the risk of neurodegenerative diseases such as Alzheimer’s disease and is associated with
poorer neurocognitive outcomes. Furthermore, HIV-uninfected (HIV-) adults with a family history of dementia
(FHD), considered a proxy for genetic markers of dementia, are at a higher risk for developing dementia and
long-term cognitive decline compared to those without FHD. We have shown that FHD may be a risk factor for
HIV-associated neurocognitive disorders as persons with FHD have significantly worse global neurocognitive
function compared to those without FHD. Nevertheless, these cross-sectional data do not address the potential
additive effect of FHD and APOE e4 on rate of global and domain-specific neurocognitive decline among older
PWH. Assessing the relationships between FHD, APOE e4 and neurocognitive decline is critical toward
identifying risk and neuroprotective factors among the vulnerable population of older PWH. Accordingly, the
proposed F31 project will follow-up on the initial cross-sectional examination of FHD and neurocognition in
order to: 1) determine whether FHD among first- and second-degree relatives and APOE e4 status are
associated with worse global- and domain-specific neurocognition in middle-to-older age PWH; 2) determine
whether FHD and APOE e4 status predict neurocognitive trajectories; and 3) explore potential effects of
demographic, neuropsychiatric, substance use, daily functioning, comorbidities, and HIV disease
characteristics on neurocognitive trajectories by FHD and APOE-e4 status. The proposed research will use
cross-sectional and longitudinal archival data of middle-to-older PWH from the Multi-Dimensional Successful
Aging Among HIV-Infected Adults and CNS HIV Antiretroviral Therapy Effects Research programs. The
opportunities afforded via this F31 mechanism will facilitate the applicant’s professional development toward
becoming an independent academic neuropsychologist dedicated to promoting neurocognitive resilience
among older PWH.
项目概要/摘要
随着高效抗逆转录病毒疗法的引入,艾滋病毒感染者 (PWH) 的寿命越来越长,并且
中老年人比例持续上升。年龄增长与以下风险增加相关
与年龄相关的神经生成疾病,包括阿尔茨海默病。慢性艾滋病毒和衰老都是
与超出正常衰老预期的认知缺陷有关。并发症的发生率也较高
年龄较大的孕妇可能还会增加患神经退行性疾病的风险。因此,当务之急是
将研究工作重点放在调查感染者神经认知障碍的预先确定的危险因素上。
神经退行性疾病被认为是部分遗传的。事实上,载脂蛋白 e4 (APOE e4)
等位基因会增加患阿尔茨海默病等神经退行性疾病的风险,并与
神经认知结果较差。此外,有痴呆家族史的未感染艾滋病毒(HIV-)的成年人
(FHD)被认为是痴呆症遗传标记的代表,患痴呆症的风险较高,并且
与没有 FHD 的人相比,长期认知能力下降。我们已经表明,FHD 可能是一个风险因素
HIV 相关的神经认知障碍,因为 FHD 患者的整体神经认知能力明显较差
与没有 FHD 的功能相比。然而,这些横截面数据并没有解决潜在的问题
FHD 和 APOE e4 对老年人整体和特定领域神经认知衰退率的累加效应
王后。评估 FHD、APOE e4 和神经认知能力下降之间的关系对于
确定老年感染者弱势群体的风险和神经保护因素。据此,
拟议的 F31 项目将跟进 FHD 和神经认知的初步横断面检查
目的: 1) 确定一级和二级亲属中是否患有 FHD 以及 APOE e4 状态
与中老年感染者的整体和特定领域神经认知能力较差有关; 2)确定
FHD 和 APOE e4 状态是否可以预测神经认知轨迹; 3)探索潜在影响
人口统计学、神经精神学、物质使用、日常功能、合并症和艾滋病毒疾病
FHD 和 APOE-e4 状态对神经认知轨迹的特征。拟议的研究将使用
多维度成功中老年艾滋病患者横断面和纵向档案数据
HIV 感染者的老龄化和中枢神经系统 HIV 抗逆转录病毒治疗效果研究项目。这
通过此 F31 机制提供的机会将促进申请人的专业发展
成为一名独立的学术神经心理学家,致力于促进神经认知弹性
老年感染者中。
