Neural tube defect risk similar in pregnancies of women with diagnosed HIV versus general populationDoes HIV increase the risk of birth defects? A new study offers some reassurance

This observational analysis examined the risk for neural tube defects among pregnancies of women with diagnosed human immunodeficiency virus (HIV) infection. The study population comprised pregnancies from women with diagnosed HIV across 15 U.S. jurisdictions during 2013-2017, compared to the general U.S. population. The main finding was that the risk for neural tube defects in this group was reported as similar to that of the general population. However, the study did not report specific effect sizes, absolute numbers, p-values, or confidence intervals for this comparison.

Safety and tolerability data, including adverse events or discontinuations, were not reported in the available evidence. The analysis did not detail specific limitations, but the evidence itself has important constraints. The study design is observational, meaning it reports an association, not causation. The findings are also limited to the specific 15 jurisdictions and the 2013-2017 timeframe, which may affect generalizability to other settings or periods.

For clinical practice, this evidence suggests that in the studied jurisdictions and period, the observed risk for neural tube defects among pregnancies in women with diagnosed HIV was not notably different from the baseline population risk. Clinicians should interpret this finding with restraint, as the lack of reported statistical measures and the inherent limitations of observational data preclude definitive conclusions about risk equivalence. The findings do not support altering current prenatal screening or counseling practices for neural tube defects specifically based on maternal HIV diagnosis alone.
