About the study: CARMA-1-PREG is investigating factors related to pre-term deliveries among HIV positive women. Research has shown that HIV+ pregnant women are 2x more likely to deliver their babies early (more than 3 weeks before their due dates), compared to women without HIV. The purpose of CARMA-1-PREG is to study the effects of particular anti-HIV medications on pregnant women and on their infants by examining two markers of cell function: the length of DNA at the ends of chromosomes (“telomeres”) and the energy producing parts of the cell (“mitochondrial DNA”). CARMA-1-PREG also investigates how HIV, anti-HIV medications and other factors (e.g. the bacterial environment of a pregnant woman’s vagina) may affect early delivery.
Why is this research important? Anti-HIV medication has dramatically reduced the risk of infants getting HIV from their HIV+ mothers (from 25% to less than 1%). However, research has demonstrated that HIV+ pregnant women are twice as likely to have a pre-term delivery when compared to women without HIV. Better understanding the factor(s) which cause these pre-term deliveries among HIV+ women is integral to the health of mothers and infants living with or exposed to HIV.
Study status: Recruiting
Who can participate: Pregnant women living with HIV who are taking, or are going to be taking, anti-HIV medication during their pregnancy.
