Summary

A total of 1900 pregnant women in the 1st trimester and their children will be enrolled and followed for two years (ORCHID study main cohort). As part of this, mother-infant pairs will be required to attend up to 10 study visits separate from routine clinic visits, these visits include 3 antenatal visits (less than or equal to 18, 24-28 and 32-36 weeks) and 16 postnatal visits (\<2 and 6 weeks, 3, 6, 12, 18, and 24 months). Participants will also be asked to engage in long-term follow-up, with visits occurring every 6 months through Month 60 (at 30, 36, 42, 48, 54, and 60 months). Measurements in mothers will include demographics and health status, HIV disease and ART use, intercurrent medical history including concomitant medication use, HIV viral load testing, ART adherence, HIV antibody testing in women without HIV; body composition, caloric intake, dysglycemia and insulin resistance (IR), lipid profiles, anthropometry, resting energy expenditure, hepatic steatosis, specimen collection (whole blood, plasma, serum, urine, placenta and breastmilk), systemic and adipose inflammation, as well as metabolites, lipid subspecies and eicosanoids. Measurements in infants will include uterine gestational age and fetal growth, as well as metabolites, lipid subspecies and eicosanoids, body composition, dysglycemia and IR, lipid profiles, anthropometry, feeding, specimen collection (cord blood, whole blood, plasma and serum) and intercurrent medical history including concomitant medication use. Additional data on maternal health in pregnancy and birth outcomes will be abstracted from medical records.

Detailed description

Dolutegravir (DTG)-based antiretroviral therapy (ART) is being scaled up as part of the preferred 1st-line ART regimen. However, DTG has recently been implicated as an obesogen that is associated with increased weight and adipose tissue gain compared to other antiretroviral agents. Obesity in pregnancy is associated with poor health outcomes for both mother and child as pregnancy is a critical period during which exposures leading to alterations in metabolic health may influence not only long-term maternal health but also fetal, neonatal, and ultimately child health. To address the gap of knowledge on the obesogenic effects of DTG in pregnant women living with HIV (WLHIV) and their children, this prospective cohort study will investigate the impact of DTG in pregnancy and its obesogenic effects on the metabolic health of WLHIV and their children, compared to women without HIV and their children. Up to 1900 pregnant women will be enrolled and followed to delivery and then as mother-infant pairs through 5 years postpartum (ORCHID study main cohort). Additionally, a nested cohort study will be conducted and enroll a subset of 108 pregnant women who are currently being followed as part of the parent ORCHID study's main cohort. This substudy will explore the associations of DTG (initiating and continuing DTG use during pregnancy) with longitudinal perturbations in subcutaneous adipose tissue (SAT) function and changes in weight and adipose tissue mass in pregnancy through 2 years postpartum in WLHIV using a comparison group of HIV-seronegative women. They will been seen at up to 3 different time points (up to 2 visits during pregnancy and 1 visit postpartum) separate from the parent study to undergo a fat biopsy procedure to extract SAT samples.

Interventions

Type	Name	Description
DEVICE	Dolutegravir-based antiretroviral therapy	This study focuses on the impact of Dolutegravir (DTG)-based antiretroviral therapy (ART) on metabolic health of women and children in pregnancy, delivery and beyond. In order to understand the potential adverse effects of DTG, pregnant women living with HIV- both those initialing DTG-based ART in pregnancy as well as those who were established on DTG-based ART prior to pregnancy, will be less than or equal to 18 weeks' gestation at enrollment to allow for detection of metabolic abnormalities as they begin to develop during the course of pregnancy. This is considered standard of care.
