BACKGROUND: Nearly 80% of patients with eosinophilic esophagitis (EoE) have coexisting atopic disease, yet a subset do not. It is unclear if this lack of atopy impacts presentation or response to therapy.
OBJECTIVES: To characterize the presentation and response to therapy in atopic versus nonatopic pediatric patients with EoE.
METHODS: A case-control study of patients with EoE aged 6 months to 18 years (between 2018 and 2021) was performed. Patients were eligible if they had allergy testing, assessment of atopic history, and at least 1 endoscopy after initiation of treatment. Patients were considered nonatopic if they had negative allergy testing and no history of significant atopy. Response to therapy was classified as complete (peak eosinophils [eos] <15/high power field [hpf]), partial (≥15 eos/hpf but at least a 50% reduction in peak eos), or nonresponse.
RESULTS: A total of 168 participants were enrolled. The majority were White (n = 141, 84%), male (n = 124, 74%), and non-Hispanic (n = 158, 95%). The mean age at diagnosis was 9.4 years (standard deviation: ±4.8 years). A total of 123 participants (73.2%) were atopic, and 45 (26.8%) were nonatopic. There was no significant difference between atopic and nonatopic for most demographics or presenting symptoms. Nonatopic participants were younger than atopic participants (8.14 vs 9.8 years, P = .046). Swallowed topical corticosteroids (STC) and food elimination diets (FED) were used at a similar rate. There were no differences in treatment response between atopic/nonatopic participants in regard to STC, FED, or STC+FED.
CONCLUSIONS: Atopic status does not significantly impact presentation or response to treatment in pediatric EoE, but a lack of atopy may be a risk for earlier onset of disease.
