|Brief Title ICMJE||A Prospective, Observational Study of HIV-Infected Pregnant Women and Their Infants at Clinical Sites in Latin American and Caribbean Countries|
|Official Title ICMJE||A Prospective, Observational Study of HIV-Infected Pregnant Women and HIV-Exposed, Uninfected Children at Clinical Sites in Latin American Countries|
By the end of 1999, it was estimated that 1.2 million children were living with HIV infection. During 1999 alone, 600,000 children were newly infected with HIV, mostly in less-developed countries. Most HIV-infected children are infected by transmission from mother to child during pregnancy, at birth, or through breast milk. Antiretroviral medications, cesarean section before rupture of membranes, and avoidance of breastfeeding are ways to reduce the risk of transmission. This study will determine mother-to-child transmission rates and the effects on infants of exposure to antiretroviral medications and mode of delivery.
Approximately 180 to 240 HIV-infected pregnant women in Mexico and Argentina will be enrolled during the first year of this 5-year study. HIV-infected women will be evaluated during pregnancy, during delivery, and 6 months after delivery. At each visit, a history will be taken and physical examination given; blood will be collected for laboratory tests.
HIV-exposed infants will be evaluated through 6 months of age. At each of 2 visits, a history will be taken and physical examination given; blood will be collected for laboratory tests; and growth will be assessed.
This is an observational, prospective cohort study to describe the characteristics of HIV-infected pregnant women and their infants at participating clinical sites in Latin America and the Caribbean where formula and antiretroviral prophylaxis of mother-to-child transmission of HIV are available. We will describe the utilization of interventions related to decreasing the risk of mother-to-child transmission, including antiretroviral prophylaxis, cesarean section before labor and before ruptured membranes, and avoidance of breastfeeding. We will describe receipt of maternal antiretroviral therapies and determine mother-to-child HIV transmission rates. This study will describe maternal adverse events during pregnancy and the postpartum period. In addition, the study will describe infant outcomes potentially related to in utero and early infant exposure to antiretroviral medications and to mode of delivery. We will enroll approximately 180-240 HIV-infected pregnant women during the first year of this planned five-year study. HIV-infected women will be evaluated antepartum, intrapartum and six months postpartum. HIV-exposed infants will be evaluated through six months of age.
