摘要

Eosinophilic gastrointestinal disorders (EGIDs) are treated with corticosteroids and food allergen elimination. However, treatment for refractory cases is not standardized. We demonstrate the efficacy of vedolizumab, an anti-α4β7 integrin agent, in 2 children with duodenal ulcers developed by non-eosinophilic esophagitis EGIDs. In both, vedolizumab was used continuously without side effects, and long-term remission has been durable. Duodenal ulcers associated with EGIDs are increasing. Vedolizumab has potential as a treatment for even upper gastrointestinal lesions in refractory EGIDs.
