Mucosal Barrier Defects in Functional Dyspepsia by Confocal Laser Endomicroscopy
Recruitment status was: Recruiting
|Study Design:||Observational Model: Case Control
Time Perspective: Prospective
|Official Title:||Minimal Changes of Gastric Mucosal Barrier in the Pathophysiologic Mechanisms of Functional Dyspepsia|
- Specific microscopic changes in the gastric mucosa as seen under the confocal endomicroscope [ Time Frame: Within the 30 minutes after injection of fluorescein ]
- the relationship among minimal changes, FD symptoms , neuropeptides and immune responses. [ Time Frame: after the immunohistochemistry of biopsy ]
Biospecimen Retention: Samples With DNA
|Study Start Date:||July 2009|
|Estimated Study Completion Date:||July 2010|
|Estimated Primary Completion Date:||March 2010 (Final data collection date for primary outcome measure)|
Asymptomatic individuals admitted for health surveillance or patients for follow up after polypectomy.
Functional dyspepsia-EPS(epigastric pain syndrome) Patients admitted to outpatient department with symptoms meeting ROME III criteria
Functional dyspepsia-PDS(postprandial distress syndrome) Patients admitted to outpatient department with symptoms meeting ROME III criteria
Confocal laser endomicrosopy is a newly developed device which allows in vivo and real time observation of gastrointestinal mucosa.In our pilot study we found that the contrast agent fluorescein sodium shew differences of leakage into intercellular spaces and crypt lumen among different patients of FD.
This study is aimed to determine if there is microscopic changes detectable in the gastric mucosal epithelium through confocal endomicroscopy of FD patients, and to evaluate the relationship among minimal changes(transmission electron microscopy and Confocal laser endomicrosopy ), FD symptoms(symptom index form) , neuropeptides and immune responses(immunohistochemistry).
