Eosinophilic esophagitis in adults: An update.

Eosinophilic esophagitis is a worldwide chronic allergic disease of the esophagus. In the last decade, there is an epidemic of this entity in the western world. Mostly seen in children and young adults, patients present with dysphagia or food impaction in the emergency room. Characteristic endoscopic findings, esophageal eosinophilia and non-responsiveness to proton pump inhibitors help make the diagnosis. Avoidance of food allergens, administration of steroidal anti-inflammatory medications and dilation of the esophagus are the mainstays of treatment. Investigations are ongoing for mucosal healing and optimum maintenance treatment.
