DESCRIPTION (provided by applicant): HIV is recognized as a devastating infection that leads to severe morbidity and earlier death. It is known that HIV infection is associated not only with disruptions in immune function but also in sleep with daytime fatigue, somnolence and impaired quality of life. Highly Active Anti-Retroviral Therapy (HAART) is now extending the life expectancy of those infected with HIV either allowing or producing chronic medical conditions and significant associated medical comorbidity. Our preliminary data indicate that both HIV infection and HAART are associated with substantial daytime fatigue. Moreover, HAART is also associated with sleep apnea, a known cause of sleep disruption and daytime somnolence. Our major hypothesis is that HIV infection, HAART, and associated alterations in humoral factors and cellular immunity lead to sleep disruption and sleep apnea, which both cause daytime dysfunction. In Specific Aim 1, we will elucidate the effects of HIV and HAART on nocturnal sleep architecture and daytime function. We hypothesize that HIV infection will be associated with sleep disruption and alterations in measures of daytime sleepiness, neurocognitive and neurobehavioral function, and quality of life. In Specific Aim 2, we will delineate the effects of HIV and HAART on the severity of upper airway obstruction and sleep. We hypothesize that HAART, but not HIV infection, is associated with an increased susceptibility for sleep apnea due to alterations in regional fat distribution and leptin. In Specific Aim 3, we will elucidate specific humoral and molecular pathways involved in the pathogenesis of upper airway, ventilatory and sleep/wake dysregulation. In this proposal, we capitalize on the well-established Baltimore site or the Multicenter Aids Cohort Study (MACS), a longitudinal study of HIV infection in gay men, to determine the impact of these factors on sleep quality, sleep apnea and daytime function. In a series of complementary murine studies, we further probe causal pathways involved in the pathogenesis of upper airway, respiratory and sleep/wake dysfunction. Conventional methods will be employed to assess sleep architecture, cellular immunity, humoral factors and daytime function, while novel analytic approaches will be used to quantify effects of HIV infection and therapy on sleep structure and upper airway function.

描述（由申请人提供）： 艾滋病毒被认为是一种毁灭性的感染，导致严重的发病率和过早死亡。 众所周知，艾滋病毒感染不仅与免疫功能的破坏有关，而且与白天疲劳、嗜睡和生活质量受损的睡眠有关。 高效抗逆转录病毒疗法（HAART）现在正在延长艾滋病毒感染者的预期寿命，这些感染者要么允许或产生慢性疾病和显著相关的医疗并发症。 我们的初步数据表明，HIV感染和HAART都与大量的日间疲劳有关。 此外，HAART还与睡眠呼吸暂停有关，这是睡眠中断和白天嗜睡的已知原因。 我们的主要假设是HIV感染、HAART以及体液因子和细胞免疫的相关改变导致睡眠中断和睡眠呼吸暂停，这两者都导致日间功能障碍。 在具体目标1中，我们将阐明HIV和HAART对夜间睡眠结构和日间功能的影响。 我们假设HIV感染与睡眠中断和日间嗜睡、神经认知和神经行为功能以及生活质量的改变有关。 在具体目标2中，我们将描述HIV和HAART对上呼吸道阻塞和睡眠严重程度的影响。 我们假设HAART，而不是HIV感染，与由于局部脂肪分布和瘦素改变而增加的睡眠呼吸暂停易感性相关。在具体目标3中，我们将阐明上呼吸道，排尿和睡眠/觉醒失调的发病机制中涉及的特定体液和分子途径。 在这项提案中，我们利用完善的巴尔的摩网站或多中心艾滋病队列研究（MACS），艾滋病毒感染的男同性恋者的纵向研究，以确定这些因素对睡眠质量，睡眠呼吸暂停和日间功能的影响。 在一系列补充的小鼠研究中，我们进一步探讨了上气道，呼吸和睡眠/觉醒功能障碍的发病机制中涉及的因果途径。 传统的方法将用于评估睡眠结构，细胞免疫，体液因素和日间功能，而新的分析方法将用于量化艾滋病毒感染和治疗对睡眠结构和上呼吸道功能的影响。
