Clinical Trial Summary

In this study the investigators will follow the neurodevelopmental outcome of children with in utero ZIKV exposure who do not have microcephaly or severe abnormalities consistent with Congenital Zika Syndrome. The ZIKV-exposed children will be compared to non-ZIKV exposed controls. Children will be assessed at age 3 and 4 years using standardized neurodevelopmental assessments. Children will also have neurodevelopmental assessment at age 5 and 7 years along with a brain MRI at age 7 years.


Description:

Zika-virus (ZIKV) infection in pregnancy can result in severe brain damage in 4-12% of cases. Children exposed to ZIKV in utero during the years of 2015-2017 are now in early childhood. Children with severe neurologic injury (Congenital Zika Syndrome; CZS) have a poor developmental outcome, however the developmental outcome of apparently normal infants following in utero ZIKV-exposure is not well known. The incidence of abnormal neurodevelopmental outcome in apparently normal children with in utero ZIKV-exposure is not known. The investigators will determine if neurodevelopmental assessment scores in children exposed to ZIKV in utero who are normal appearing differ from norms. The investigators hypothesize that ZIKV-exposed normal appearing children will have lower multi-domain developmental assessment scores compared to normative samples. The investigators hypothesize that the presence of mild postnatal non-specific cranial US findings is associated with persistent lower developmental assessment scores compared to ZIKV-exposed children who had normal cranial US and quantitative imaging will find structural and functional brain differences between ZIKV-exposed children and controls.. The investigators will perform a prospective developmental outcome study at 2 sites: 1) Department of Atlántico, Colombia through collaboration with BIOMELAB, the research center of Dr. Carlos Cure, and 2) Children's National, Washington, DC. The objective of the study is to determine whether children who were exposed to ZIKV in utero and who do not have CZS have abnormalities in neurodevelopment during early childhood and at school age. The primary outcome at early childhood will be neurodevelopmental assessment scores at age 3 and 4 years. Scores will be compared between Zika-exposed children and controls. The primary outcome at school age will be neurodevelopmental assessment scores at age 5 and 7 years and quantitative brain MRI at 7 years.

Intervention

Other:
Neurodevelopmental assessments
The investigators will evaluate multiple domains of neurodevelopment at age 3, 4, 5 and 7 years using parental questionnaires and child exams. At age 7 years, the children will have a non-sedated quantitative brain MRI.
