We assessed the value of screening for cognitive abnormalities in a chronically infected HIV population (N = 388) and investigated the association with clinical correlates. The mean age was 48 years (±11), the majority of the patients were male (89%), the median duration of infection was 6 years [interquartile range (IQR) = 2-12], the median CD count was 600 (IQR = 450-780), and 326 (84%) had a viral load below 200 copies/mL. Screening for cognitive complaints was applied using the three Simioni questions and the international HIV dementia scale (iHDS). Neuropsychological assessment (NPA) included 13 well-validated tests assessing motor speed, concentration, and memory. A total of 69 patients completed the NPA. CD4 (nadir), viral load, combination antiretroviral therapy (cART) duration, and the presence of comorbidities were evaluated for associations with NPA result. A total of 127 (33%) reported cognitive complaints during screening. The sensitivity and specificity of the Simioni questions were 82% and 24%, respectively. Adding the iHDS resulted in a sensitivity of 50% and a specificity of 73%. A CD4 nadir count <50 cells/m was associated with an abnormal NPA (p = 0.01). Comorbidities were more prevalent in patients with an abnormal NPA, although not statistically significant (p = 0.276). Age, current CD4, viral load, and cART duration were not associated with abnormal NPA. The authors conclude that current screening strategies are insufficient in detecting HIV-associated neurocognitive disorder. A low CD4 nadir is associated with poor neurocognitive outcome in HIV.
我们评估了在慢性感染HIV的人群(N = 388)中筛查认知异常的价值,并调查了其与临床相关因素的关联。平均年龄为48岁(±11),大多数患者为男性(89%),感染的中位持续时间为6年[四分位间距(IQR)= 2 - 12],CD计数中位数为600(IQR = 450 - 780),326例(84%)患者的病毒载量低于200拷贝/毫升。使用三个西米奥尼问题和国际HIV痴呆量表(iHDS)进行认知主诉筛查。神经心理学评估(NPA)包括13项经过充分验证的测试,用于评估运动速度、注意力和记忆力。共有69例患者完成了NPA。评估了CD4(最低点)、病毒载量、联合抗逆转录病毒治疗(cART)持续时间和合并症与NPA结果的关联。共有127例(33%)患者在筛查期间报告有认知主诉。西米奥尼问题的敏感性和特异性分别为82%和24%。加上iHDS后,敏感性为50%,特异性为73%。CD4最低点计数<50个细胞/微升与NPA异常相关(p = 0.01)。合并症在NPA异常的患者中更常见,尽管无统计学意义(p = 0.276)。年龄、当前CD4、病毒载量和cART持续时间与NPA异常无关。作者得出结论,目前的筛查策略在检测HIV相关神经认知障碍方面不足。CD4最低点低与HIV患者神经认知预后不良相关。
