Prospective Cohort Study of HIV and Zika in Infants and Pregnancy (HIV ZIP)
Study Overview
Status
Conditions
Detailed Description
This is a two-phase prospective international cohort study of pregnant women and their infants from those pregnancies whose goals are to compare the incidence of ZIKV infection among pregnant women with and without HIV infection and to determine the risk of adverse maternal and child outcomes associated with ZIKV/HIV co-infection across clinical sites in the continental U.S., P.R. and Brazil.
Phase I will enroll pregnant women/infant pairs who are: (1) infected with HIV only; (2) infected with ZIKV only; (3) infected with HIV and ZIKV; and (4) not infected with HIV or ZIKV. Phase I will assess the feasibility of enrolling a total of 200 pregnant women/infant pairs within a year, with a target of 150 HIV-infected women, 50 HIV-uninfected women from the continental U.S. sites only, and a minimum of 20 who are co-infected with HIV and ZIKV by the end of pregnancy.
Should the feasibility of Phase I prove successful, Phase II will commence by enrolling up to 1,800 additional pregnant women/infant pairs to the 4 groups described above. The comparison group of HIV-uninfected pregnant women/infant pairs from P.R and Brazil (ZIKV-infected and uninfected) will be obtained from data collected in the concurrent International Prospective Observational Cohort Study of Zika in Infants and Pregnancy (ZIP study).
All HIV-infected and uninfected study participants will be tested for ZIKV. Enrolled women will be followed throughout their pregnancy and up to six weeks postpartum. Infants born to enrolled women will be followed for a full year after birth. Thereafter, the infants born to women at continental U.S. and P.R. sites also implementing the Surveillance Monitoring for Antiretroviral Therapy (ART) Toxicities (SMARTT) study may be followed up yearly until adulthood through SMARTT depending on the availability of funds.

IPD Plan Description
De-identified participant data will be entered into the National Institute of Child Health and Human Development (NICHD) Data and Specimen Hub (N-DASH) system.
Data from the ZIP study, conducted in Zika-endemic areas, may be merged with HIV ZIP. In most cases, ZIP will have the exact same infant assessments as HIV ZIP.
