Outcome Measures
Primary Outcomes (1)
To characterize the TRPV1 expression in the esophageal mucosa of children with esophagitis and to correlate the TRPV1 expression with severity of mucosal inflammation and microscopic changes.
5 years
Study Arms (2)
EXPERIMENTAL
Children undergoing an endoscopy for retrosternal chest pain, epigastric pain, regurgitation, heart burn or dyspepsia.
CONTROL
Children undergoing an endoscopy for reasons not stated in the experimental group condition (i.e. celiac disease, rectal bleeding, polyps, weight loss, malabsorption).
Eligibility Criteria
Children undergoing an endoscopy procedure for gastrointestinal symptoms and chest pain or reasons other than those listed in the exclusion criteria.
You may qualify if:
- Retrosternal and/or epigastric pain and esophagitis
- Retrosternal and/or epigastric pain but no macroscopic or microscopic esophagitis
- Gastrointestinal symptoms such as diarrhea, regurgitation, rumination, vomiting, feeding aversion, non-organic failure to thrive, celiac disease with no macroscopic or microscopic esophageal inflammation
