Eosinophilic esophagitis and other eosinophilic disorders of the gastrointestinal tract.

Eosinophilic disorders of the gastrointestinal tract (EGID) are a group of diseases characterized by an eosinophilic inflammation limited to the GI tract. EoE is by far the most common EGID and is an atopic chronic/relapsing eosinophilic inflammation of the esophagus. It is now recognized as an increasingly common cause of esophageal dysfunction, fibrosis, stricture, and food impaction in children and adults. There are globally accepted guidelines for its treatment that are based on the use of proton pump inhibitors (PPI), corticosteroids, and diet. Many clinical trials have been published on the use of biologics in this disease. Non-EoE-EGID is a rare, more severe disease. No globally accepted guidelines exist for their treatment and diagnosis. Corticosteroids are at the moment the most effective treatment of those diseases.
