title: Gastrointestinal manifestations of food allergies.
abstract: The rates of eosinophilic gastrointestinal disorders appear to be increasing. The most common of these is eosinophilic esophagitis (EoE) which is a clinicopathologic condition consisting of characteristic symptoms and endoscopic features accompanied by a pan-esophageal, acid resistant epithelial eosinophilia of greater than equal to 15 per high power field. Typical symptoms include dysphagia and abdominal pain. Typical endoscopic features include pallor, plaques, furrows, concentric rings. Complications include food impactions and strictures. EoE resolution with food elimination diets provides evidence that EoE is a food-antigen driven process. In vitro and microarray studies have identified specific immunologic factors underlying EoE pathogenesis. Other gastrointestinal manifestations of food intolerances/allergy include food protein induced enterocolitis syndrome.
