Definitions
Eosinophilic esophagitis (EoE): The diagnosis of EoE was based on symptoms associated with esophageal dysfunction and the presence of intraepithelial eosinophils in the esophagus (≥15 eosinophils/hpf), after excluding secondary causes of esophageal eosinophilia.1,3
Food-induced immediate response of the esophagus (FIRE) : FIRE is defined as reproducible unpleasant symptoms occuring immediately after intake of certain foods, unrelated to the well-characterized swallowing diffuculties in EoE.4
Pollen-food allergy syndrome (PFAS): PFAS was diagnosed in pollen sensitized patients who demonstrated oropharyngeal symptoms (itching/tingling, mild erythema, mild angioedema) triggered with pollen cross-reactive food(s).6,8
