Description:
Eosinophilic esophagitis (EoE) is a clinicopathological condition characterized clinically by symptoms of esophageal dysfunction in the absence of acid reflux, with typical endoscopic findings and eosinophilia on biopsy. This article looks into the historical clinical recognition and description of EoE, in particular clinical manifestations, natural history, and epidemiology. Additionally, the evolution of endoscopic recognition and development of clinical trials are described: EoE is an isolated disease of the esophagus, although it is associated with other antigen-driven diseases such as asthma, rhinitis, and atopic dermatitis. After initial case reports which were mostly not typical of the disease state now described, the first case series were described in 1993 and 1994 in adults, and 1995 in children. Although rarely seen before 2000, the disease is now commonly recognized. Randomized clinical trials have now been performed on topical steroids, and on biological agents targeted against IL-5, IL-13, and other mediators. Therapy with dilatation may be best guided by measures of compliance and distensibility. Work is needed on biomarkers of the disease's severity and progression, and predictive indexes of complications. EoE is a relatively new disease of increasing importance. It represents an important diagnosis in patients with upper gastrointestinal symptoms and must be considered in all patients with dysphagia where the diagnosis is not certain and in all patients who have an assumed diagnosis of reflux but are not responding to standard reflux therapy.
