Abstract
The purpose of this review is to provide the current understanding of the role of allergens/antigens, the use of allergy testing, and to elucidate the role of the allergist in the management of eosinophilic esophagitis (EoE). EoE is a T2 immune disorder that is part of the atopic march. EoE patients commonly have multiple concurrent allergic disorders. Recent studies demonstrate that, like other allergic diseases, epithelial barrier dysfunction plays a key role in EoE pathogenesis. Aero- and food allergens have been identified as EoE triggers. EoE management includes the assessment and avoidance of its instigating antigens. Due to the integrated T2 immune response in an allergic individual, proper EoE care should include the control of underlying atopic disorders. EoE is a complex disease that is optimally managed by a multidisciplinary approach. This review provides an update on the role of the allergist in the clinical management of EoE.
