Cleft lip and palate and periconception COVID-19 infection in five arab countries.

Background: Little is known about factors associated with the severity of cleft lip with or without cleft palate (CL/P) especially during the COVID-19 pandemic with its dramatic changes. Objectives: The aim of this multi-national study is to measure the association between CL/P severity, COVID-19 infection, and fear of COVID-19 in five Arab countries. Methods: This cross-sectional study took place in major governmental hospitals in five Arab countries from November 2020 to April 2023. Participants were infants born with CL/P and their mothers who were in their 1st trimester during the COVID-19 pandemic. Clinical examination was carried out, and CL/P cases were grouped according to phenotype: cleft lip and palate (CLP) versus cleft lip (CL), cleft extension (incomplete versus complete), and site (unilateral versus bilateral) to assess severity. Information on maternal COVID-19 infection and fear of COVID-19 were gathered. Results: The study recruited 273 CL/P infants. Maternal COVID-19 infection during one-month pre-gestation and 1st trimester was significantly associated with higher odds of CL/P severity (AOR = 2.707; P = 0.002) than mothers without the COVID-19 infection. Using supplements during pregnancy showed a protective effect (AOR = 0.573; P = 0.065). Conclusion: Mothers infected with COVID-19 before and during pregnancy had more than twofold higher odds of having an infant with a more severe CL/P phenotype. [ABSTRACT FROM AUTHOR]
