为了确定1型人类免疫缺陷病毒(HIV)生殖道脱落与垂直传播之间的关系,在妇女和婴儿传播研究中进行了一项病例对照亚研究。检测产前宫颈阴道灌洗标本上清液中HIV-1 RNA和细胞微球中HIV-1 RNA和DNA的含量。多变量分析比较了26名将艾滋病毒传播给婴儿的妇女和52名没有将艾滋病毒传播给婴儿的妇女;33%接受抗逆转录病毒联合治疗,65%接受单一治疗。HIV-1 DNA存在(OR, 3.42; 95%可信区间[CI], 0.76-15.4; P=.11)和滴度(OR, 1.66; 95% CI, 0.93-2.99; P=.09)的校正优势比(ORs)表明,垂直传播与HIV-1 DNA存在独立关联。当分析仅限于阴道和非选择性剖宫产时,HIV-1 DNA平均滴度每增加1个对数与传播风险显著增加相关(OR, 2.28; 95% CI, 1.09-4.78; P= 0.03)。细胞相关的生殖道隔室在HIV-1垂直传播的病理生理学和预防中是重要的
To determine the association between genital tract shedding of human immunodeficiency virus (HIV) type 1 and vertical transmission, a case-control substudy was conducted within the Women and Infants Transmission Study. Antenatal cervicovaginal lavage specimens were assessed for HIV-1 RNA in the supernatant and HIV-1 RNA and DNA in cell pellets. Multivariate analyses compared 26 women who transmitted HIV to their infants with 52 women who did not; 33% received combination antiretroviral therapy, and 65% received monotherapy. Adjusted odds ratios (ORs) for the presence (OR, 3.42; 95% confidence interval [CI], 0.76–15.4; P=.11) and titer (OR, 1.66; 95% CI, 0.93–2.99; P=.09) of HIV-1 DNA suggested that there is an independent association with vertical transmission. When analyses were restricted to vaginal and nonelective cesarean deliveries, each one-log increase in mean titer of HIV-1 DNA was associated with a significantly higher risk of transmission (OR, 2.28; 95% CI, 1.09–4.78; P=.03). The cell-associated genital tract compartment is important in the pathophysiology and prevention of vertical HIV-1 transmission
