The goal of this observational study is to assess the birth outcomes of HIV-positive women delivering in hospitals in Eswatini who are receiving dolutegravir (DTG) or other anti-retroviral (ARV) drug regimens. The main question the study aims to answer is, what is the proportion of neural tube defects among live and stillborn infants delivered by:
Participants will be interviewed for information on HIV testing and antiretroviral therapy history, other medical history of selected conditions (e.g., diabetes, malaria, TB) and potential birth defect exposures. Photographs will be taken of the infants. Data on mothers' pregnancy history, birth outcomes, and HIV and ARV information (as applicable) will be collected from patient records.
This is an observational study conducted at five high volume hospitals in Eswatini, in which birth defect and other data will be collected at the time of delivery (or hospital admission for miscarriages and medical abortions) for all women. The overall aim of this study is to evaluate the birth outcomes of HIV-positive women who are receiving DTG or other ARV drug regimens. The primary research objectives are to: 1) determine the proportion of neural tube defects among live and stillborn infants delivered by HIV-positive women on DTG at conception; 2) determine the proportion of neural tube defects among live and stillborn infants delivered by HIV-negative women; and 3) determine the proportion of neural tube defects among live and stillborn infants delivered by HIV-positive women on non-DTG ART at conception. Secondary objectives are to determine overall general prevalence of major external birth defects and other pregnancy outcomes and any associations with other factors (e.g., maternal age, gravida). Data on mothers' pregnancy history, birth outcomes, and HIV and ARV information (as applicable) are collected from patient charts, registers, reporting forms and databases for all women. Women of live or stillborn infants with birth defects are consented for interviews capturing detailed history and exposure data and photographs of newborns' birth defects. Data collection will be for approximately 24 months. Blinded interview data and photographs are reviewed by a medical geneticist for confirmatory defect diagnosis. We will describe rates and 95% confidence intervals (CI) for birth defects among infants by maternal HIV and ART status.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| HIV-positive DTG preconception | HIV status defined as a documented positive result in the perinatal and/or maternity register or other clinical source record. Preconception drug exposure determined using date of DTG initiation and LMP date or gestational age at delivery (if LMP not available). ART at conception is defined as maternal ART that started up to 8 weeks after the calculated LMP date, which would be up to 6 weeks after the estimated date of conception. As this is the group of interest, sample size target was determined as 10,000. | ||
| HIV-negative | Women with the last HIV test result recorded during pregnancy or labor and delivery as negative. | ||
| HIV-positive on non-DTG ARV preconception | HIV status defined as a documented positive result in the perinatal and/or maternity register or other clinical source record. Preconception drug exposure determined using date of ARV initiation (e.g., efavirenz) and LMP date or gestational age at delivery (if LMP not available). ART at conception is defined as maternal ART that started up to 8 weeks after the calculated LMP date, which would be up to 6 weeks after the estimated date of conception. Other groups to be included as informed by the data (e.g., HIV+ not on ART a conception, unknown ART at conception, etc). |
