Can E-cadherin Found in Tissue/Blood be Valuable in Identifying & Monitoring Patients With Post-proton Pump Inhibitor (PPI)-Responsive Heartburn
The purpose of this research study is to determine in heartburn patients with nonerosive disease if detecting the presence of a fragment of the protein e-cadherin in esophageal epithelium or the amount of fragments of e-cadherin in blood can be used to monitor healing of esophagitis treated with a proton pump inhibitor (PPI). The hypothesis is that the presence of fragments of e-cadherin in esophageal epithelium or the amount of fragments of e-cadherin in blood can you useful as a biomarker for the healing of esophagitis in patients successfully treated with a PPI.

|Official Title:||Can Detection of Fragments of Cleaved E-cadherin in Tissue and/or Blood be of Value for Identifying and Monitoring Patients With PPI-responsive Heartburn?|
- Dexlansoprazole [ Time Frame: 4 weeks ] [ Designated as safety issue: No ]Primary outcome measure: To determine whether detection of cleaved fragments of e-cadherin in esophageal biopsies and in serum can discriminate between nonerosive patients with PPI-responsive and PPI-refractory heartburn.
- Dexlansoprazole [ Time Frame: 4 weeks ] [ Designated as safety issue: No ]To determine whether serum levels of N-terminal fragments of e-cadherin can be useful to monitor esophageal healing in patients with nonerosive PPI-responsive heartburn.
