Eosinophilic esophagitis prevalence in adults with dysphagia or heartburn: preliminary results

Background/aim Eosinophilic esophagitis (EoE) is a chronic immunemediated condition characterized clinically by esophageal dysfunction and pathologically by infiltration of > 15 eosinophils per high-powered field (HPF) in the esophageal mucosa, since other causes of esophageal eosinophilia (including proton-pump inhibitor responsive esophageal eosinophilia [PPI-REE]) are excluded. It occurs worldwide especially in children and adults < 40 years, affecting notably Caucasian male. Treatment includes dietary elimination of food allergens and topical corticosteroids. The aim of this study is to determine the prevalence of EoE in adults with dysphagia or heartburn followed in the Immunology and Gastroenterology Services of the Hospital Universitario Antonio Pedro, Universidade Federal Fluminense, Niteroi, Brazil.
