Basics

Description

Eosinophilic esophagitis (EoE) is a chronic immune-mediated esophageal disease characterized clinically by variable symptoms of esophageal dysfunction and pathologically by localized eosinophilic inflammation.
The diagnosis is established in symptomatic patients who have the following:
- At least 15 eosinophils/HPF isolated to the esophagus on endoscopic biopsies
- Persistent eosinophilic infiltrate in esophageal biopsies after a trial of proton pump inhibitor (PPI) therapy

Epidemiology

Incidence rates range from 0.7 to 10 per 100,000 person-years, and prevalence from 0.2 to 43 per 100,000.
3:1 male-to-female ratio
Peaks of onset in childhood and 3rd–4th decade

Pathophysiology

The exact pathophysiology of EoE is unknown but likely involves an immune response to environmental antigens in genetically predisposed individuals.
Environmental factors (food and possibly aeroallergens) trigger inflammatory response mediated by type 2 T-helper (Th2) cells.
Genetic polymorphisms which predispose to EoE include eotaxin-3, thymic stromal lymphopoietin, and filaggrin.
