Prevalence of food allergy diagnosis in pediatric patients with atopic dermatitis referred to allergy and/or dermatology subspecialty clinics

Abstract

Atopic dermatitis (AD) is a common chronic inflammatory pediatric skin disorder, affecting up to 25% of children.1 Children with AD are at higher risk for food allergy (FA); approximately 30% to 50% of children with AD have a history of FA.2-5 Further, the prevalence of AD and FA has increased over time.6 Prior studies examining FA prevalence in children with AD often conflated multiple types of FA, including immediate immunoglobulin E (IgE)–mediated symptoms and food-triggered atopic dermatitis (FTAD), and did not clearly distinguish the two entities.
