目的:探讨分娩时母亲病毒载量对HIV-1母婴传播风险的影响。设计:一项巢式病例对照研究,前瞻性随访HIV- 1感染的孕妇及其婴儿。设置:多中心纽约市围产期艾滋病毒传播合作研究。参与者:51名生育HIV-1感染婴儿的妇女与54名非传播母亲的CD 4+细胞计数五分位数频率匹配。主要观察指标:使用基于核酸序列的扩增检测系统检测分娩前后血浆中HIV-1病毒RNA的母体数量。结果:105例妇女中73例(70%)检出病毒RNA,传播者中位病毒载量为16000 RNA拷贝/ml,非传播者中位病毒载量为6600 RNA拷贝/ml(P < 0.01)。当校正分娩前母体CD 4+计数时,具有可测量病毒载量的女性传播HIV-1的可能性是病毒载量低于检测值的女性的近6倍[校正比值比(AOR),5.8; 95%置信区间(CI),2.2-15.5]。经CD 4计数校正后,log 10病毒载量的围产期传播优势比为2.7(95%CI,1.5-5.1)。当按HIV-1疾病分期分层时,log 10病毒载量与传播之间存在显著关联的唯一群体是CD 4+计数> 500 x 106/l的无艾滋病妇女(AOR,9.1; 95%CI,2.6-31.5)。结论:在没有艾滋病和晚期免疫抑制的妇女中,高母体病毒载量增加了围产期传播HIV-1的可能性。没有晚期疾病的感染艾滋病毒-1的孕妇,被其他人证明具有最低的围产期传播风险,可能从分娩时识别和减少病毒载量的努力中受益最大。
Objective:To determine the effect of maternal viral load at delivery on the risk of perinatal transmission of HIV-1. Design:A nested case–control study within a prospectively followed cohort of HIV- 1-infected pregnant women and their infants. Setting:The multicenter New York City Perinatal HIV Transmission Collaborative Study. Participants:Fifty-one women who gave birth to HIV-1-infected infants were frequency-matched within CD4+ cell count quintiles with 54 non-transmitting mothers. Main outcome measures:Maternal quantity of HIV-1 viral RNA was assayed in plasma obtained near delivery using the nucleic acid sequence-based amplification assay system. Results:Viral RNA was detected in 73 (70%) out of 105 women and the median viral load was 16 000 RNA copies/ml in transmitters and 6600 in non-transmitters (P < 0.01). When adjusted for maternal CD4+ count near delivery, women with measurable viral load were nearly sixfold more likely to transmit HIV-1 than women with viral load below detection [adjusted odds ratio (AOR), 5.8; 95% confidence interval (CI), 2.2–15.5]. The odds ratio for perinatal transmission of log10 viral load, adjusted for CD4 count was 2.7 (95% CI, 1.5–5.1). When stratified by the stage of HIV-1 disease, the only group with significant association between log10 viral load and transmission were AIDS-free women with CD4+ count > 500 x 106/l (AOR, 9.1; 95% CI, 2.6–31.5). Conclusions:High maternal viral load increases the likelihood of perinatal transmission of HIV-1 in women without AIDS and advanced immunosuppression. HIV-1-infected pregnant women without advanced disease, shown by others to have the lowest risk of perinatal transmission, may benefit the most from efforts to identify and decrease viral load at delivery.
