RESUMO
INTRODUCTION: Celiac disease is a chronic autoimmune disorder that occurs following the ingestion of gluten, in genetically predisposed individuals. Patients with celiac disease, especially children, are likely prone to develop allergic reactions to different food allergens. However, the relationship between food allergy and celiac disease remains not elucidated. The aim of this pioneering study was to evaluate the prevalence of allergic food sensitization in children with celiac disease in Morocco. METHODS: A total of 57 children with confirmed celiac disease, including 25 males and 32 females with a mean age of 8.6 ± 4.4 years, underwent a food allergen-specific immunoglobulin E (IgE) screening. This screening was conducted using a multiparametric immunodot assay (Euroline Food "Maghreb," Euroimmun). Statistical analysis was performed using R software. RESULTS: Among the 57 cases tested, the overall rate of IgE-mediated sensitization to food allergens was found to be 48% (27/57), dominated by chicken, with 51.9% (14/27), followed by almond, 40.7% (11/27), sesame, 40.7% (11/27), potato 33.3% (9/27), and apple 18.5% (5/27). Of the s-IgE positive cases, 74% were sensitized at least to one allergen, 37% (10/27) were sensitized to both chicken and almond allergens. A significant correlation was observed between almond, sesame, chicken, and potato. CONCLUSION: The current study highlighted a high prevalence of food allergen sensitization in children with celiac disease. This underlines the potential benefit in screening for food allergy in celiac patients.
