Avoidant/Restrictive Food Intake Disorder in Diet‐treated Children With Eosinophilic Esophagitis

Abstract

Eosinophilic esophagitis (EoE) is an inflammatory condition of the esophagus with rising incidence in children. Owed to potential adverse effects and high costs of EoE medications, strict elimination diets are often employed as a mainstay of long-term EoE therapy in children. Currently, there are no effective tests to pinpoint food protein triggers in children with EoE. Therefore, EoE elimination diets are often broad (including milk, soy, wheat, egg, fish/shellfish, and nuts) and can greatly alter a child's baseline eating habits. Herein, we describe 2 cases of avoidant/restrictive food intake disorder (ARFID) in children with remitted EoE maintained on an elimination diet. We also present comorbidity data on ARFID and diet-treated EoE from our pediatric EoE clinic. This is the first report of disordered eating associated with EoE therapy. As EoE is becoming more common, close monitoring of intake and growth in patients treated with elimination diets will be key.
