Eosinophilic esophagitis: clinical presentation in children.

Eosinophilic esophagitis (EoE) is increasing in western nations. Symptoms in infants and young children include feeding difficulties, failure to thrive, and gastroesophageal reflux. School-aged children may present with vomiting, abdominal pain, and regurgitation; adolescents and adults with dysphagia and food impaction. Delayed diagnosis increases risk of stricture formation. Children with untreated EoE have tissue changes resembling airway remodeling. Endoscopy does not always correlate. Management centers on food elimination. Approaches include skin prick and patch testing, removal of foods, or an amino acid formula diet. Long-term elimination diets can produce nutritional deficiencies and have poor adherence.
