Association of eosinophilic esophagitis and food pollen allergy syndrome

Eosinophilic esophagitis (EoE), an inflammatory condition of the esophagus, is an important cause of dysphagia. The fibroinflammatory response, if not addressed, may result in advanced disease.1 Initially thought to be rare, the incidence of EoE is increasing, currently ranging from 1.3 to 9.5 per 100,000 in various series.1,2 Despite the increased incidence, the pathophysiology of this disease is not well understood.3 EoE is associated with a high sensitization rate to both foods and aeroallergens,4 although the role sensitization plays is not completely clear.
