We read with interest the original paper entitled “Pregnancy and neonatal outcomes in women with HIV-1 exposed to integrase inhibitors, protease inhibitors and non-nucleoside reverse transcriptase inhibitors: an observational study”, published by Floridia and colleagues online on 1-Jan-2020. The authors compared a wide variety of maternal and birth outcomes based upon use of triple antiretroviral regimens in pregnancy among women living with HIV. Since all regimens contained a backbone of two nucleoside reverse transcriptase inhibitors, comparison was made between the third antiretroviral drug class in the regimen, integrase strand transfer inhibitors (INSTIs) versus protease inhibitors (PIs) versus non-nucleoside reverse transcriptase inhibitors (NNRTIs). A key strength of the analyses reported by Floridia and colleagues is the fact that 80% of the pregnancy outcomes evaluated involved women prospectively enrolled, minimizing the chance of selection bias. The authors reported the absence of any major differences between the use of the three drug classes, INSTIs, NNRTIs, and PIs in pregnancy and outcomes of interest. Clearly, this can be very reassuring to women living with HIV undergoing preconception counseling or during an initial antenatal visit, as efficacious antiretroviral regimens are essential to preventing both maternal HIV disease progression and infant HIV acquisition. In citing study limitations, the authors correctly note the small sample sizes, particularly with respect to the group of women receiving INSTIs in pregnancy. Importantly, in the adjusted analysis of determinants of low birth weight, the point estimates for NNRTI and PI use indicate a higher risk of low birth weight compared with INSTI use. Yet the small sample size contributes to imprecision, as noted in the wide confidence intervals. Rather than a conclusion of no difference between the three drug classes and the outcome of low birth weight, it would be more appropriate to report insufficient evidence to conclude whether there is a difference or not by ARV class in association with LBW. In the last decade, UNAIDS estimates indicate that there has been no decline in the number of women living with HIV who experience pregnancy, an estimated 1.3 million annually [1]. Increasingly, a larger proportion of these women are accessing antiretroviral treatment (ART) in pregnancy, estimated at just under 60% globally in 2018 [1]. While this has unquestionably contributed to the greater than 60% reduction in infant acquisition of HIV, from over 450,000 in 2000 to an estimated 160,000 in 2018, the safety of antiretroviral use in pregnancy has not been systematically and rigorously studied. In 2018, with a report from Botswana of a possible association between use of integrase strand transfer inhibitor-based treatment regimens initiated prior to conception and neural tube defects [2], a spotlight was placed on safety monitoring of antiretroviral use in pregnancy. Against this backdrop, there have been numerous reports of adverse birth outcomes, higher rates of infectious morbidity and mortality, poorer growth and development delays among infants exposed in utero to both HIV and antiretroviral drugs compared with infants born to women without HIV [3–5]. It is incredibly important to compare the safety of antiretroviral treatment regimens used
