Pathophysiology of Eosinophilic Esophagitis

The Pathophysiology of Eosinophilic Esophagitis

Eosinophilic esophagitis (EoE) is an emerging disease characterized by esophageal eosinophilia (>15eos/hpf), lack of responsiveness to acid-suppressive medication and is managed by allergen elimination and anti-allergy therapy. Although the pathophysiology of EoE is currently unsubstantiated, evidence implicates food and aeroallergen hypersensitivity in genetically predisposed individuals as co...

Lymphocytic esophagitis mimicking eosinophilic esophagitis

A 74-year-old male with a history of dysphagia for 3 years presented with acute food impaction. Endoscopy showed a tight distal stricture with course rings at the middle third of the esophagus. Biopsies taken from the middle third of the esophagus showed marked infiltration of the intraepithelial lymphocytes mainly in a peripapillary distribution. The immunostains showed presence of CD3 and CD5...

Eosinophilic esophagitis

Eosinophilic esophagitis (EoE) is an atopic condition of the esophagus that has become increasingly recognized over the last decade. Diagnosis of the disorder is dependent on the patient's clinical manifestations and histologic findings on esophageal mucosal biopsies. Patients with eosinophilic esophagitis should be referred to both an allergist and gastroenterologist for optimal management, wh...

Eosinophilic esophagitis: A subset of eosinophilic gastroenteritis.

Eosinophilic gastroenteritis (EG) was first described over 50 years ago. Despite its long history, it remains an ill-defined and poorly understood entity. EG can present in a number of ways, none of which are exclusive to the disorder. EG has features of allergy and immune dysregulation but does not clearly fit into the category of allergic or immune disorder. While EG has been reported to affe...
