Key clinical point: Patients with eosinophilic esophagitis (EoE) who test positive for food and environmental allergens may report a lower response to proton-pump inhibitor (PPI) treatment, a first-line treatment for EoE.
Major finding: Positive food allergen testing predicted lower odds of histologic response (adjusted odds ratio [aOR] 0.15; P = .0006) and symptom response (aOR 0.22; P = .03) to PPI therapy. Patients with a higher number of positive environmental allergens detected on skin-prick testing (≥10 vs <10) were less likely to respond to PPI (21.0% vs 53.9%; P = .03).
Study details: Findings are from a retrospective study including 61 adults with newly diagnosed EoE who underwent formal allergy testing for food and environmental allergens and received PPI therapy twice daily after EoE diagnosis.
