Abstract Eosinophilic esophagitis (EoE) has been associated with allergic diseases of the airways and skin. Here, we review the current literature on the sensitization pattern of adult EoE patients and critically discuss the diagnostic and therapeutic tools available. Most EoE patients have elevated total IgE levels in serum and are sensitized to aero- and food allergens as assessed by measuring specific IgE levels and/or the skin prick test. Whereas in children with EoE sensitization to food allergens predominate, in adults EoE symptoms do not correlate with IgE sensitization to specific food allergens. However, in two thirds of adult EoE patients, sensitization to cross-reactive plant allergen components have been be detected, mainly to profilins and PR10 proteins. So far, food triggering EoE can only be identified by an elimination diet and following reintroduction controlled by endoscopy and histology. Further research is required to elucidate the role of allergens in the pathogenesis of EoE and develop appropriate tools for diagnostic and specific treatment. 2014 S. Karger AG, Basel.
