Clinical Trial
Elimination diet effectively treats eosinophilic esophagitis in adults; food reintroduction identifies causative factors.
Adults with eosinophilic esophagitis (EoE) typically present with dysphagia and food impaction. A 6-food elimination diet (SFED) is effective in children with EoE. We assessed the effects of the SFED followed by food reintroduction on the histologic response, symptoms, and quality of life in adults with EoE. ⋯ An elimination diet significantly improves symptoms and reduces endoscopic and histopathologic features of EoE in adults. Food reintroduction re-initiated features of EoE in patients, indicating a role for food allergens in its pathogenesis. Foods that activated EoE were identified by systematic reintroduction analysis but not by skin-prick tests.
