Transient Receptor Potential Vanilloid One (TRPV1) Receptor Expression in Children With Retrosternal Pain (TRPV1)

October 21, 2015 updated by: Manu Sood, Medical College of Wisconsin

Capsaicin-sensitive Transient Receptor Potential Vanilloid One (TRPV1) and Tyrosine Kinase (TrkA) 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 Overview

Status

Completed

Conditions

Detailed Description

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.

Cohorts and Interventions

Group / Cohort
EXPERIMENTAL
Children undergoing an endoscopy for retrosternal chest pain, epigastric pain, regurgitation, heart burn or dyspepsia.
