概括
乌干达痴呆症队列研究调查了撒哈拉以南非洲艾滋病毒感染和没有艾滋病毒的老年人中阿尔茨海默病和相关痴呆症 (ADRD). 这项研究旨在确定风险因素,并改善对该脆弱人群中ADRD的理解.
科学领域:
- 神经科学是一个神经科学.
- 老年学是一门学科.
- 传染性疾病 传染性疾病
背景情况:
- 抗逆转录病毒疗法 (ART) 使撒哈拉以南非洲 (sSA) 的2500多万艾滋病毒感染者 (PWH) 能够老化.
- 老年PWH可能面临更高的阿尔茨海默病和相关痴呆症 (ADRDs) 负担,由于慢性炎症和增加的危险因素.
- 有限的数据存在于ADRD流行,进展和预测因素在sSA中,特别是在PWH中.
研究的目的:
- 为了解决乌干达老年人,特别是艾滋病毒感染者的ADRD理解的差距.
- 为深入研究建立一个前性队列研究 (乌干达痴呆症队列研究 - UDCS).
- 研究ADRD的风险和保护因素,临床特征,诊断工具和社会影响.
主要方法:
- UDCS建立在一个为期10年的生活质量研究的基础上,招募PWH接受抑制性ART和没有HIV的年龄/性别类似对照.
- 参与者接受了15个可修改的ADRD风险因素的表型化和年度认知测试.
- 该队列包括大约600名艾滋病毒感染和无艾滋病毒感染的老年人 (平均年龄62岁),除了婚姻状况外,他们的人口统计数据相似.
主要成果:
- 已确定的ADRD风险因素,如高血压 (20%),吸烟 (41%),虚弱 (60%) 和抑郁 (40%) 在队列中普遍存在.
- 这些风险因素的患病率在艾滋病毒感染者和未感染者之间是相似的.
- 艾滋病毒阳性和艾滋病毒阴性参与者之间的人口特征在很大程度上相似,艾滋病毒阴性组中已婚个体的频率更高.
结论:
- 在乌干达,UDCS将大大提高对ADRD的理解,包括危险因素,表型,诊断和社会影响.
- 该研究正在扩大,包括通过认知评估,生物标志物和脑部成像进行深度表型.
- 将收集数据和标本,创建生物库,促进在非洲和全球范围内协调跨国ADRD研究.
