RESUMO

OBJECTIVES: We sought to determine whether pregnant individuals with human immunodeficiency virus (HIV) prescribed integrase strand transfer inhibitor (INSTI) antiretrovirals (ARVs) achieve viral suppression faster than individuals taking non-INSTI regimens and to determine whether there were differences in viral suppression at delivery among INSTI ARVs. METHODS: This is a retrospective cohort study of pregnant individuals with HIV who delivered a live infant during the study period (January 1, 2009-December 31, 2020). Patients' ARV therapy (ART) was classified as including INSTI or non-INSTI. We compared the proportion of individuals with viral suppression at delivery by group and individual INSTI ARVs using χ2 and Fisher exact tests. A log rank test was used to compare time to viral suppression on ARVs. RESULTS: During the study period, 168 individuals delivered a live infant. Most of the patients were diagnosed as having HIV before pregnancy and had taken ARVs before conception (76%), but fewer than half had an undetectable viral load at the first antenatal visit (45%). During pregnancy, 46% were prescribed INSTI and 54% were prescribed non-INSTI ARVs. Most had an undetectable HIV RNA viral load at delivery (75% INSTI and 72% non-INSTI, P = 0.7). The time to viral suppression was similar between groups (log rank test P = 0.43). Viral suppression at delivery was similar among INSTI ARVs: raltegravir (53%), elvitegravir (88%), dolutegravir (73%), and bictegravir (88%) (P = 0.13). CONCLUSIONS: Despite recommendations to prescribe INSTI in pregnancy for rapid viral suppression, we did not find a significant difference in time to viral suppression when pregnant individuals were taking non-INSTI ARVs. We did not find that one INSTI ARV was superior for viral suppression.

RESUMO

BACKGROUND: We sought to determine whether pregnant women with HIV prescribed integrase strand transfer inhibitor (INSTI) were more likely to have viral suppression at delivery and any increased risk of adverse infant outcomes. METHODS: This was a retrospective, statewide cohort study of women with HIV and their HIV-exposed infants who delivered in South Carolina from 2008 to 2019. Women's antenatal AVRs were classified as INSTI or non-INSTI. We compared the percentage of women with undetectable HIV RNA viral load (<40 copies/mL) at delivery between groups. We compared the percentage of HIV-exposed singleton infants who were born preterm delivery, low birth weight, and small for gestational age and had confirmed perinatal HIV infection. Categorical outcomes were compared using the χ2 test or Fischer exact test. RESULTS: A total of 832 infants, including 11 sets of twins, were exposed to maternal HIV. Detailed antiretroviral regimens were available for analysis in a third of mother-infant pairs (n = 315). Half of the infants were exposed to INSTI (159) and half to non-INSTI antiretrovirals (156). Most women had an undetectable viral load at delivery (80% INSTI and 73% non-INSTI, P= 0.11). The percentage of singleton infants with adverse outcomes was similar between INSTI and non-INSTI groups: preterm delivery (21% and 16%, P = 0.3), low birth weight (19% and 21%, P = 0.7), small for gestational age (11% vs 9%, P = 0.5), and perinatal HIV infection (2.5% and 1.3%, P = 0.7). CONCLUSIONS: We observed that viral suppression before delivery was similar between pregnant women prescribed INSTI and non-INSTI antiretroviral therapy. The percentage of infants with adverse outcomes was similar when exposed to INSTI and non-INSTI antiretroviral therapy.
