Refractory Pediatric Fibrostenotic Eosinophilic Esophagitis Treated With Dupilumab.

Eosinophilic esophagitis (EoE) is a progressive inflammatory disease of the esophagus. Untreated or uncontrolled disease over time can lead to the development of fibrosis and formation of strictures. Once the patient develops strictures, it is difficult to treat with the available medical therapies and will often require esophageal dilations. The Food and Drug Administration recently approved dupilumab for the treatment of EoE in patients older than 12 years. The clinical trials excluded patients with esophageal strictures. We describe a case of EoE with fibrostenotic stricture who had stricture resolution while on dupilumab therapy.
