RESUMO
The aims were to evaluate the impact of maternal HIV infection diagnosis timing on infant outcomes. The outcomes of interest included preterm delivery (PTD) and confirmed infant HIV infection. Data for all HIV-exposed infants from 2004-14 were obtained. Maternal HIV infection diagnosis timing was categorized as: perinatal (PHIV), adult infection before conception, and after conception. Infant outcomes were compared according to timing of maternal HIV diagnosis. Bivariate outcomes were compared using χ2 tests. Continuous variables were compared using Kruskal-Wallis tests. Logistic regression was used to determine predictors of PTD and infant HIV infection. Most women were diagnosed with HIV before conception: PHIV (21, 3%), before conception (431, 69%), and post-conception (176, 28%). Women diagnosed with HIV as an adult before conception were more likely to deliver preterm (P = 0.007). Prenatal care was associated with lower risk of PTD (aOR 0.1, 95% CI 0.04-0.5). Six infants contracted HIV. Infant HIV infection was more likely in women who did not take antiretroviral therapy (aOR 13.5, 95% CI 2.5-72.1) or delivered preterm (aOR 5.3, 95% 1.1-25.1). Women with PHIV were more likely to deliver at term, and there were no HIV infections among PHIV-exposed infants. These findings are reassuring to PHIV women who desire pregnancy.

PURPOSE: Our primary aim was to determine if combined antiretroviral therapy (cART) increased the risk of poor infant outcomes among women with HIV. METHODS: Maternal antiretroviral regimens were classified as mono-(mARV), dual (dARV), cART, and no ARV. Differences in dichotomous outcomes were compared using χ2 tests and continuous outcomes were compared using Kruskal-Wallis tests. Predictors of preterm delivery (PTD), low birth weight, and perinatal HIV infection were determined using logistic regression. RESULTS: During the 11-year study period, 643 mother-baby pairs with HIV exposure were eligible for analysis. Non-Hispanic, Black women were more likely to report mARV or no ARV use (p=.03). Women not taking ARVs were more likely to have PTD (p=.01). Prenatal care was associated with a reduction in PTD [aOR 0.12 (95% CI 0.03-0.5)] and perinatal HIV infection [aOR 0.1 (95% CI 0.01-0.7)]. CONCLUSIONS: Maternal cART and race were not associated with PTD. Rather, absence of prenatal care and lack of ARV use during pregnancy increased the risk of PTD and perinatal HIV infection.
