Food avoidance strategies in eosinophilic oesophagitis

Area of Science:

• Gastroenterology
• Immunology
• Pediatrics

Background:

• Eosinophilic oesophagitis (EoE) is a chronic inflammatory disease causing significant morbidity, including fibrosis and strictures.
• A multidisciplinary approach is crucial for managing EoE patients due to its complexity.

Purpose of the Study:

• To review the role of dietary elimination in managing pediatric EoE, particularly in patients unresponsive to proton-pump inhibitors (PPIs).
• To discuss various dietary elimination strategies and their effectiveness.

Main Methods:

• Review of current literature on EoE management, focusing on dietary interventions.
• Analysis of different elimination diet approaches (step-up vs. step-down, elemental diets, six-food elimination diets).
• Emphasis on personalized dietary strategies and monitoring.

Main Results:

• Food sensitivity drives EoE inflammation in many children unresponsive to PPIs.
• Common triggers include milk, wheat, egg, soy, meats, and grains.
• Elemental or six-food elimination diets are most effective for rapid remission; step-up approaches offer better patient acceptance and fewer endoscopies.

Conclusions:

• Dietary elimination is a cornerstone treatment for pediatric EoE.
• Personalized, monitored dietary approaches are recommended.
• Ongoing research aims to improve patient selection, allergen identification, non-invasive diagnostics, and tolerance induction for EoE treatment.
