Eosinophilic esophagitis: update on management and controversies

Area of Science:

• Gastroenterology
• Immunology
• Allergy

Background:

• Eosinophilic esophagitis (EoE) is a chronic, allergen-driven immune-mediated disease.
• It is a leading cause of dysphagia and foregut symptoms in children and adults.
• Recent research has expanded knowledge on genetic/environmental risk factors, inflammation, and esophageal remodeling complications.

Purpose of the Study:

• To review recent research progress in eosinophilic esophagitis, focusing on adult patients.
• To discuss advancements in minimally invasive diagnostic techniques and potential surrogate markers.
• To examine current and future therapeutic strategies for EoE.

Main Methods:

• Review of recent scientific literature on eosinophilic esophagitis.
• Discussion of novel diagnostic tools like mucosal impedance and functional lumen imaging.
• Analysis of therapeutic trial outcomes for topical glucocorticoids, diet elimination, and biologic therapies.

Main Results:

• Ongoing development of minimally invasive techniques to assess EoE activity.
• Evaluation of mucosal impedance and functional lumen imaging as potential biomarkers.
• Continued support for topical glucocorticoids and food elimination diets as first-line treatments.
• Emerging targeted biologic therapies show promise based on improved understanding of EoE pathogenesis.

Conclusions:

• Significant progress has been made in understanding EoE, leading to improved diagnostic and therapeutic approaches.
• Novel tools and targeted therapies are advancing EoE management, with a focus on reducing invasiveness and optimizing treatment protocols.
• Future research directions include refining elimination diets and developing effective biologic treatments for eosinophilic esophagitis.
