Summary

This study looked at specific immune cells in the esophagus of children with eosinophilic esophagitis (EoE) compared to healthy children. Researchers counted these cells and also studied the microbiome. The goal was to better understand the disease, not to test a treatment. 35 children participated.

Inclusion Criteria: * children 1-18 years * presenting with symptoms suggestive of EoE * requiring an upper gastrointestinal endoscopy with biopsies of the esophageal mucosa in order to confirm or exclude the diagnosis * Children paired for age in whom an endoscopy performed to explore symptoms of EoE revealed another condition (peptic oesophagitis, achalasia), or children paired for age in whom an endoscopy with biopsies has been performed to explore chronic abdominal or epigastric pain or suspected chronic inflammatory bowel disease, will be include as control subjects Exclusion Criteria: * immune deficiency * auto immune diseases
