Eosinophilic esophagitis (EE) is a chronic esophageal inflammation increasingly diagnosed, characterized by eosinophil buildup. Key symptoms include difficulty swallowing and risk of food impaction, with potential for esophageal stricture.

Area of Science:

  • Gastroenterology and Immunology
  • Pathology of the Esophagus

Context:

  • Eosinophilic esophagitis (EE) is a chronic TH2-type inflammatory esophageal disorder.
  • First recognized over a decade ago, its prevalence is rising, potentially matching inflammatory bowel diseases.
  • Diagnostic criteria include >24 eosinophils/HPF in esophageal epithelium.

Purpose:

  • To define the characteristics, diagnosis, and management of eosinophilic esophagitis.
  • To highlight the increasing recognition and prevalence of EE.
  • To outline the clinical presentation and long-term risks of EE.

Summary:

  • EE involves eosinophils, T-cells, and mast cells, with elevated IL-5 and TNF-alpha expression.
  • Primary symptom is dysphagia (difficulty swallowing) with a risk of food impaction.

  • Endoscopic findings include reddish furrows and white exudates; long-term risk is esophageal stricture due to fibrosis.

    • Impact:

    • Increased recognition of EE as a significant chronic gastrointestinal condition.
    • Understanding the pathophysiology aids in developing targeted therapies.
    • Current treatments include corticosteroids, leukotriene antagonists, dietary changes, and dilation.
