Polysensitization to aeroallergens and food in eosinophilic esophagitis in a pediatric population.

There are few studies on eosinophilic esophagitis (EE) in the pediatric population in Europe. We present our data and emphasize the following findings: a) all patients had symptoms of allergic respiratory disease prior to receiving a diagnosis of EE with polysensitization (aeroallergens, food allergens); and b) in contrast with the results of earlier studies, food sensitization in our series most often corresponded to legumes.
