Abstract

HIV-1 transmission in utero accounts for 20-30% of vertical transmission events in breast-feeding populations. In a prospective study of 463 HIV-1-infected mothers and infants, illness during pregnancy was associated with 2.6-fold increased risk of in-utero HIV-1 transmission [95% confidence interval (CI) 1.2-5.8] and bacterial vaginosis with a three-fold increase (95% CI 1.0-7.0) after adjusting for maternal HIV-1 viral load. Interventions targeting these novel risk factors could lead to more effective prevention of transmission during pregnancy.

摘要

HIV-1 经母婴垂直传播在母乳喂养人群中占 20-30%。在对 463 例 HIV-1 感染母婴的前瞻性研究中,母亲孕期患病会使 HIV-1 经母婴垂直传播的风险增加 2.6 倍[95%置信区间(CI)1.2-5.8],细菌性阴道病使风险增加 3 倍[95%CI 1.0-7.0],但校正 HIV-1 病毒载量后,这两种因素的影响仍有统计学意义。针对这些新的危险因素进行干预,可能会更有效地预防孕期母婴垂直传播。
