Translating new developments in eosinophilic esophagitis pathogenesis into clinical practice

Area of Science:

• Gastroenterology
• Immunology
• Allergy

Background:

• Eosinophilic esophagitis (EoE) is a chronic allergic inflammatory condition.
• It can progress to severe fibrostenotic disease, necessitating early diagnosis and management.
• Understanding EoE pathogenesis is key to refining treatment strategies.

Purpose of the Study:

• To discuss current therapeutic and management strategies for EoE.
• To clarify the role of proton pump inhibitors (PPIs) in EoE diagnosis and treatment.
• To outline alternative therapies for PPI-nonresponsive cases.

Main Methods:

• Review of recent findings on EoE pathogenesis.
• Analysis of the relationship between EoE and PPI-responsive esophageal eosinophilia (PPI-REE).
• Discussion of diagnostic criteria and therapeutic options for EoE.

Main Results:

• Proton pump inhibitor-responsive esophageal eosinophilia (PPI-REE) may represent a spectrum of EoE.
• PPIs possess therapeutic properties beneficial for both GERD and EoE.
• PPIs should be viewed as a treatment, not a diagnostic tool, for EoE.

Conclusions:

• Early diagnosis and long-term maintenance therapy are crucial for managing EoE.
• For PPI-nonresponsive EoE, dietary or steroid therapy should be considered.
• Dilation is an adjunctive treatment for advanced fibrostenotic EoE.
