What is Eosinophilic Esophagitis

Eosinophilic Esophagitis (EoE) is a chronic, immune-mediated inflammatory condition of the esophagus characterized by predominant infiltration of eosinophils in the esophageal mucosa. The disease arises from an aberrant type 2 helper T-cell (Th2) immune response to environmental or food antigens in genetically predisposed individuals. Key cytokines, including interleukin-4, interleukin-5, and interleukin-13, drive the recruitment and activation of eosinophils, leading to persistent inflammation, tissue remodeling, and, over time, fibrosis of the esophageal wall. EoE often coexists with other atopic diseases such as asthma and allergic rhinitis, and its prevalence has increased in recent decades, particularly among males and individuals of Caucasian descent. Clinically, EoE presents with symptoms of esophageal dysfunction, including dysphagia, food impaction, and, in children, feeding difficulties and failure to thrive. Diagnosis is based on a combination of clinical presentation, endoscopic findings (such as rings, furrows, and white exudates), and histological confirmation of at least 15 eosinophils per high-power field on esophageal biopsy, after excluding other causes. Treatment options include swallowed topical corticosteroids like budesonide, which reduce local inflammation, and biologic therapies such as dupilumab, which target key cytokines in the Th2 pathway. Long-term management aims to control symptoms, induce histological remission, and prevent complications such as strictures.

Eosinophilic Esophagitis (EoE) is driven by a network of immune and inflammatory mediators, with key therapeutic targets emerging from the central role of Type 2 (Th2) immune responses. Core targets include the cytokines interleukin 13 (IL13), interleukin 4 (IL4), and thymic stromal lymphopoietin (TSLP), which orchestrate eosinophil recruitment and activation through upregulation of eotaxin-3 and other effectors. Additional targets such as colony stimulating factor 2 (CSF2/GM-CSF), KIT proto-oncogene (KIT), and prostaglandin D2 receptor 2 (PTGDR2/CRTH2) support the survival and activation of eosinophils and mast cells, contributing to chronic inflammation and tissue remodeling. Intracellular signaling molecules like Janus kinase 1 (JAK1) and the glucocorticoid receptor (NR3C1) further modulate the intensity of cytokine signaling and anti-inflammatory responses, respectively. The therapeutic potential of these targets is underscored by the development and approval of biologics and small-molecule inhibitors that intervene at multiple points in the inflammatory cascade. Agents targeting IL13, IL4, and TSLP—such as cendakimab, dupilumab, and tezepelumab—have demonstrated efficacy in reducing eosinophilic inflammation and improving clinical outcomes, with dupilumab now FDA-approved for EoE. JAK inhibitors and KIT antagonists are also in clinical development, addressing both upstream cytokine signaling and effector cell activation. By targeting these validated and emerging molecular pathways, current and investigational therapies promise to improve disease control, reduce steroid dependence, and address unmet needs in EoE management.
