International Cohort Study of Children Born to Women Infected With Zika Virus During Pregnancy

2019-10-15 11:11:31 | BioPortfolio

Summary

The International Cohort Study of Children Born to Women Infected with Zika Virus During Pregnancy study will enroll children from the ZIP study and other ZIP 2.0 Protocol Team approved studies. ZIP 2.0 will continue the prospective longitudinal follow-up of up to 400 children. Approximately 200 born to women with documented ZIKV infection during their pregnancy and 200 born to women without documented ZIKV infection during their pregnancy matched by site and birth sex will be compared to determine the long-term neurodevelopmental outcomes of in utero ZIKV exposure. Each participant will be followed for about 2 years, beginning at approximately 18 months through 42 months of age.

Description

The International Prospective Observational Cohort Study of Zika in Infants and Pregnancy (ZIP) study has leveraged 10 international sites to follow mother-infant dyads prospectively in pregnancy and postpartum to determine the incidence and outcomes of Zika Virus (ZIKV) infection. The ZIP study has collected demographic, physical, environmental, laboratory, and delivery outcome data in relation to mother-infant pairs with and without ZIKV infection. Infants born to women enrolled in the ZIP study are followed for 1 year and undergo regular physical and neurological assessments to identify clinical or developmental outcomes.

The International Cohort Study of Children Born to Women Infected with Zika Virus During Pregnancy (ZIP 2.0) study will enroll children who themselves or whose biological mothers were previously enrolled in the ZIP study and other ZIP 2.0 Protocol Team-approved studies. The goal of the extended follow-up of children enrolled in the ZIP study is to define/determine the long-term neurodevelopmental outcomes of in utero ZIKV exposure. Assessments include growth, neurodevelopmental, audiologic, ophthalmologic, and other clinical outcomes. Evaluations will occur about every 6 months over about a 2-year period beginning at approximately 18 months of age. Follow-up evaluations and assessments will allow for the determination and comparison of long-term neurodevelopmental outcomes among in utero ZIKV-exposed and ZIKV-unexposed children.

After parent(s)/legal guardian(s) permission is obtained for the child's participation in ZIP 2.0, several means to contact them will be requested. Parents will be asked whether or not messages can be left for each of the phone numbers provided and if messages can contain information regarding the nature of the study.

This is a prospective, observational, international cohort study of children previously enrolled in the ZIP study or other approved studies that will continue the longitudinal follow-up of children born to mothers with confirmed or presumptive in-utero ZIKV exposure. We expect to compare approximately 200 children with documented confirmed or presumptive in-utero ZIKV exposure and 200 controls matched by site and birth sex without documented confirmed or presumptive in-utero ZIKV exposure at age approximately 18 months, and at age 42 months.

The primary objective is to determine the long-term neurodevelopmental outcomes among children born with documented confirmed or presumptive in-utero ZIKV exposure. The secondary objectives are to compare the long-term effects (e.g., on growth, vision, hearing and ND) of in-utero ZIKV-exposure compared to unexposed children.

An arbovirus in the FLAVIVIRUS genus of the family FLAVIVIRIDAE. Originally isolated in the Zika Forest of UGANDA it has been introduced to Asia and the Americas.

A viral disease transmitted by the bite of AEDES mosquitoes infected with ZIKA VIRUS. Its mild DENGUE-like symptoms include fever, rash, headaches and ARTHRALGIA. The viral infection during pregnancy, however, may be associated with other neurological and autoimmune complications (e.g., GUILLAIN-BARRE SYNDROME; and MICROCEPHALY).
