Abstract

Eosinophilic esophagitis (EE) is a recently recognized form of pan-esophagitis, which is characterized by the presence of at least 15 eosinophils per high power field on esophageal histology. EE is closely associated with atopic disorders and occurs predominantly in male patients. Young children are more likely to be sensitized to food allergens whilst aeroallergen sensitization predominates in older children and adults--a pattern reminiscent of the "atopic march". EE presents with a diverse range of gastrointestinal symptoms, including regurgitation, vomiting, feeding difficulties or refusal in infancy, in addition to dysphagia and food bolus impaction in older children and adults. The diagnosis may also be ascertained incidentally in patients undergoing gastroscopy for other suspected gastrointestinal conditions, such as gastroesophageal reflux disease or celiac disease. Complications mainly relate to subepithelial remodeling and fibrosis which may result in dysmotility, dysphagia and esophageal strictures. The proportion of EE patients at risk of these complications is unknown due to a paucity of data on the natural history of EE. There are only few randomized controlled trials assessing the efficacy of treatment modalities for EE, which currently either involve food allergen elimination or use of swallowed aerosolized corticosteroids. This article aims to discuss the complex issues of the diagnosis and long-term management that confront clinicians who care for children with EE.
