Filter by:Eosinophilic esophagitis (EoE) is a chronic inflammatory esophagus disease that is presented in patients with a history of recurrent dysphagia. EoE is closely related to other pathologies with an immuno-allergic etiopathogenesis such as atopic dermatitis (AD), IgE-mediated food allergy, allergic rhinitis and bronchial asthma. While the importance of the correlation between diet and food allergy has been largely demonstrated, less is known about the exact role of sensitization to aerollergens in the progression and recrudescence of symptoms. In support of this correlation there is evidence of a seasonal trend in the new diagnoses of EoE, of the possibility of the de-novo onset of the pathology following massive exposure to a specific aeroallergen and the demonstration that the degree of esophageal eosinophilia varies according to the climatic zone and the season of the year. The detailed knowledge of this correlation could clarify some aspects of the etiopathogenesis and natural history of EoE, improve and personalize the clinical-diagnostic management of affected patients and provide new therapeutic targets. Our aim is evaluating the possible existence of a correlation between the recrudescence of dysphagia symptoms and a specific month of the year and/or specific season.
This study evaluates the diagnostic efficacy of CAP System (capsulated hydrophilic carrier polymer) for recombinant tropomyosin from shrimp extract in discriminating between subjects allergic to shrimp with CAP positive subjects allergic to mites, crustaceans asymptomatic but with a positive CAP to shrimp, to identify those at greatest risk of food reactions.
