Association of eosinophilic gastrointestinal disorders with other atopic disorders

Abstract

Eosinophilic esophagitis is a chronic disease that leads to either persistent symptoms or, at times, intermittent "flares." It shares many features with other atopic diseases (asthma, allergic rhinitis, and atopic dermatitis), including the following: T helper 2 cells and eosinophils play a critical role in the pathogenesis of the disease; avoidance of allergens promotes remission of disease and symptom control; and locally applied corticosteroids provide control. Finally, most patients who have eosinophilic gastrointestinal disorders have an associated atopic disease.
