Prospective observational study on the characteristics of eosinophilic esophagitis in southeast Spain

Eosinophilic esophagitis (EoE) is a chronic esophageal atopic disease because sensitization to aeroallergens and foods allergens is very common.

This study is the first work that studies multiple characteristics of EoE in the southeast of Spain to know whether EoE in the patients of this region is similar to that of other regions of Spain in terms of demography, symptoms, and atopic characteristics.

It is an observational prospective study of patients diagnosed with EoE at Granada (Spain). We recorded demographic data (age, sex, and personal history of atopy), clinical data (impaction and dysphagia), allergologic data (prick test and specific immunoglobulin E) to foods, aeroallergen, and pan-allergens, and other endoscopic-histologic data and comorbidities.

The demographic, allergologic, and endoscopic characteristics of patients with EoE in Granada were similar to the rest of Spain, except the higher frequency of sensitization to olive pollen, food allergy, and anaphylaxis reactions.

The higher frequency of sensitization to olive pollen and food allergy with severe clinical manifestations (anaphylaxis) in patients with EoE in Granada could have a negative impact on patients' quality of life.
