PD21 - Diagnosis and treatment of eosinophilic esophagitis guided by micro-arrays technology

Background Eosinophilic esophagitis (EoE) is an immune-mediated disease of the esophagus characterized by symptoms related to esophageal disfunction and histollogically by an eosinophil-predominat inflammation. Multiple therapies have been suggested to be helpful in EoE including endoscopic dilation, medical therapy and withdrawal dietary but, the election of what food should be excluded is very difficult. Component-resolved diagnosis and microarray technology have been recently introduced into clinical allergy practice, and may be particularly useful in food-sensitized allergic patients.
