Eosinophilic esophagitis: updated consensus recommendations for children and adults

Area of Science:

• Gastroenterology
• Immunology
• Pathology

Background:

• Eosinophilic esophagitis (EoE) is a recognized condition with increasing prevalence.
• Existing 2007 guidelines for EoE diagnosis and treatment are underutilized by physicians.
• Significant advancements in understanding EoE have emerged since 2007.

Purpose of the Study:

• To provide updated recommendations for EoE diagnostics, genetics, allergy testing, therapeutics, and complications.
• To propose a new conceptual definition of EoE based on current evidence.
• To address advances and controversies in EoE management.

Main Methods:

• Systematic literature review of EoE research published since September 2006.
• Expert panel consensus among 33 physicians in allergy/immunology, gastroenterology, and pathology.
• Synthesis of evidence to inform updated guidelines and definitions.

Main Results:

• EoE is characterized as a chronic, immune/antigen-mediated disease with esophageal dysfunction and eosinophilic inflammation.
• Diagnostic criteria emphasize both clinical and pathological features.
• Key therapeutic options include dietary elimination, topical corticosteroids, and esophageal dilation.
• New insights include genetic factors (TSLP gene) and proton pump inhibitor-responsive esophageal eosinophilia.

Conclusions:

• Updated guidelines are needed due to the underutilization of previous recommendations.
• EoE is an antigen-driven disease involving multiple pathways.
• Continued research is essential for refining diagnostic methods and treatment approaches.
