Eosinophilic esophagitis for the otolaryngologist

Area of Science:

• Gastroenterology
• Otolaryngology
• Allergy Immunology

Background:

• Eosinophilic Esophagitis (EE) is an emerging condition characterized by eosinophilic infiltration of the esophageal mucosa.
• It presents with symptoms ranging from dysphagia to food impaction, often mimicking gastroesophageal reflux disease (GERD).
• A familial predisposition and association with allergies are noted in patients with EE.

Purpose of the Study:

• To review current diagnostic and treatment strategies for Eosinophilic Esophagitis (EE).
• To highlight the challenges in diagnosing EE, particularly within the otolaryngology field.
• To emphasize the need for increased awareness and further research into the genetic factors of EE.

Main Methods:

• A comprehensive literature review was conducted.
• Diagnostic criteria, including histopathology and endoscopic findings, were examined.
• Treatment options and their efficacy were evaluated.

Main Results:

• Definitive diagnosis of EE relies on esophageal biopsy showing eosinophilic infiltration.
• Transnasal esophagoscopy has improved diagnostic capabilities for otolaryngologists.
• Despite increased awareness, EE remains frequently misdiagnosed, often as GERD.

Conclusions:

• EE diagnosis requires a high index of suspicion and is confirmed by histopathology.
• Otolaryngologists play a key role in recognizing and diagnosing EE.
• Further genetic research is essential to understand the underlying familial components of EE.
