Transient Receptor Potential Vanilloid One (TRPV1) Receptor Expression in Children With Retrosternal Pain
We would like to evaluate the changes in nerve innervation and TRPV1 receptor expression along with microscopic changes associated with heart burn and abdominal pain
|Study Design:||Observational Model: Case Control
Time Perspective: Prospective
|Official Title:||Capsaicin-sensitive Transient Receptor Potential Vanilloid One (TRPV1) and Tyrosine Kinase (TrkA) Receptor Expression in Children With Retrosternal Pain|
- 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. [ Time Frame: 5 years ] [ Designated as safety issue: No ]
Biospecimen Retention: Samples Without DNA
We are collecting a single mucosal biopsy during an endoscopy procedure.
|Study Start Date:||December 2006|
|Estimated Study Completion Date:||December 2013|
|Estimated Primary Completion Date:||December 2013 (Final data collection date for primary outcome measure)|
Children undergoing an endoscopy for retrosternal chest pain, epigastric pain, regurgitation, heart burn or dyspepsia.
Children undergoing an endoscopy for reasons not stated in the experimental group condition (i.e. celiac disease, rectal bleeding, polyps, weight loss, malabsorption).
Approximately 5% of children between 10-17 years of age report symptoms of heart burn, epigastric pain or regurgitation. This study will evaluate the changes in nerve innervation and TRPV1 receptor expression in children having upper endoscopy for evaluation of heart burn and abdominal pain.
