Background: Data regarding food sensitization and food allergy in developing countries are lacking. We sought to explore the frequency and pattern of sensitization to food allergens among a sample of Egyptian allergic patients. Methods: This cross-sectional study included 1373 allergic patients. They were subjected to thorough history taking, skin prick test, serum specific IgE (sIgE) level. Patients with evidence of sensitization to food were subjected to food elimination followed by an open oral food challenge (OFC) test. Results: Four-hundreds and nineteen patients (30.5%) (76 children and 343 adults) had evidence of sensitization to one or more food allergen.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
