Eosinophilic esophagitis is an emerging disease worldwide, as documented by recent case series from Switzerland, Australia, Italy, Spain, Japan, England, and the United States.1,2 Eosinophilic esophagitis mimics gastroesophageal reflux disease and may result in narrowing and stricture of the esophagus.1-3 This disease is differentiated from reflux esophagitis on the basis of the magnitude of mucosal eosinophilia and a lack of response to acid suppression.4 We report findings from a population-based demographic study of the pediatric population with eosinophilic esophagitis residing in the vicinity of our medical center (Hamilton County, Ohio), a region with a single pediatric gastroenterology and pathology provider.
