Filter by:This is a double-blind,randomised,placebo-controlled clinical trial.We would like to investigate the safety and efficacy of Jianpi Qinghua granule(a Chinese herbal compound) combined with half-dose omeprazole in treatment of non-erosive reflux disease(NERD).
Primary Objective: Evaluate response to NERD treatment between patients with normal endomicroscopy findings compared with patients with abnormal endomicroscopy findings. Secondary Objectives: To evaluate the role of probe based endomicroscopy in the diagnosis of NERD by evaluating dilated intercellular spaces, evaluation of IPCL, and quantification of fluorescein leak. Quality of life at study entry and end of study. Compare two medications under study within each group as a subgroup analysis.
White light endoscopy remains the gold standard technique to evaluate gastrointestinal tract. Gastroesophageal Reflux Disease (GERD) is defined as presence of reflux symptoms (heartburn and regurgitation) associated or not with lesions in esophageal mucosa. Based on findings at videoendoscopy GERD patients can have a complicated reflux disease (erosive esophagitis) or not and be considered as a non erosive reflux disease (NERD). 60% of GERD patients have normal endoscopy (NERD) and requires further studies to achieve a definitive diagnosis. Based on this fact is that the study will be focus on NERD patients. Recently an image-enhanced endoscopic technology using a pre-processor band-limited light called Optical Enhancement system (OE system™), was developed (Pentax Medical). This new technology combines digital signal processing with optical filters that limit the spectral characteristics of the illumination light. The new innovated optical filters achieve higher overall transmittance by connecting the peaks of the hemoglobin absorption spectrum (415 nm, 540 nm and 570 nm) creating a continuous wavelength spectrum. There are two modes with different OE filters (Mode 1 and Mode 2). Mode 1 is designed to improve visualization of microvessels with a sufficient amount of light, and Mode 2 is designed to improve contrast of white-light observation by bringing the color tone of the overall image closer to that of natural color. In addition, new scopes has been developed which combines high definition images with optical magnification called Magniview™. These scopes increase the image up to 136 times with a better quality of image than standard scopes without optical zoom. Sharma et al. evaluated esophageal changes in NERD patients using a similar pre-processor filter called Narrow Band Imaging (NBI). They found that a significantly higher proportion of patients with NERD had an increased number, dilation and tortuosity of the microscopic intrapapillary capillary loops (IPCLs), and were considered the best predictors for diagnosing NERD. They used optical chromoendoscopy technology (NBI) associated to magnification scopes (Olympus GIF Q240Z, 115x), but they did not evaluated if the contribution with this technology to the observations found in GERD patients were as a result of the NBI or the magnification scopes. The investigators opinion is that chromoendoscopy is useful but is the magnification what makes up the difference.
The purpose of this study is to demonstrate the superiority of efficacy of CJ-12420, once daily (QD), compared to placebo in patients with non-erosive reflux disease at Week 4
This clinical study hypothesized that S-pantoprazole 10mg would be effective to treat Non erosive Reflux Disease than placebo.
Gastroesophageal reflux disease(GERD) mainly related to the reflux of stomach content induced by the dysfunction of lower esophageal sphincter. Proton pump inhibitors (PPI) can effectively block gastric acid secretion but the drug reactions and the degree of improvement in symptoms are sometimes unpredictable. The aim of this study is to investigate the association between the clinical efficacy of PPI in patients with GERD and the personal physical status by Ryodoraku and ANSWatch.
Gastroesophageal reflux disease (GERD), a common chronic disorder in the veteran population, is associated with drug costs exceeding $ 10 billion/year. Only 30-40% of patients with reflux symptoms have erosive esophagitis. The vast majority suffers from non erosive reflux disease (NERD), a condition in which standard endoscopy fails to identify any mucosal breaks and is unable to confirm the diagnosis. Unfortunately, a gold standard for the diagnosis of NERD does not exist. Narrow band imaging (NBI) utilizes spectral narrow band filters (incorporated into standard endoscopes) and helps to see abnormal areas not identified during standard endoscopy. Preliminary results have shown that NBI endoscopy may represent a significant improvement over standard endoscopy for the diagnosis of NERD. The purpose of this study is to accurately diagnosis non acid reflux disease by using a blue light (also known as NBI)upper endoscopy technique.
The purpose of this study is to find out if people who have non-erosive reflux disease (NERD) have changes the investigators can see with a microscope (called confocal endomicroscopy) that is used during endoscopy (a camera scope evaluation of the inside of your stomach and swallowing tube). Traditionally the investigators have used trials of acid blocking medications (PPIs), endoscopy and measurements of acid in the swallowing tube (the esophagus) to determine if the investigators think acid is causing troublesome symptoms. The medical community believes that these symptoms are due to increased spaces between the cells that make up the swallowing tube. The investigators can directly see those spaces with a new microscope that the investigators can pass through the camera scope. Participants will be assigned to take one of two medications omeprazole and sucralfate (both approved medications for stomach symptoms) to treat their symptoms and record how well the treatment works. The investigators then will look to see if the microscope can predict which medication will work best for patients in the future. The investigators also plan to measure the acid levels in your swallowing tube and do a camera evaluation of your swallowing tube and stomach as this is standard for patients with your symptoms. The investigators will compare the results of those studies to the microscope findings.
Proton pump inhibitor (PPI) is widely used in patients with gastroesophageal reflux disease (GERD), however, some patients fail to respond to PPI therapy. Recent reporters suggest that depressive disorders, anxiety, sleep dysfunction were related with the symptomatic responses to a PPI treatments. Nevertheless, the predictive factors of response to PPI treatment still remain controversial. Therefore, the aims of this study were to investigate the efficacy of PPI therapy, and to evaluate the predictors of the PPI response in patients with symptomatic GERD by using the questionnaire which consisted of GERD symptoms, GERD impact scale (GIS), Epworth sleepiness scale (ESS), Pittsburgh sleep quality index (PSQI), Hospital anxiety and depression scale (HADS), and WHO quality of life scale abbreviated version (WHOQOL-BREF).
