Filter by:This study looks at the effect on basal and pentagastrin-stimulated acid output of 40 mg Esomeprazole (Nexium) administered orally and intravenously as a 15-minute infusion to people with symptoms of Gastroesophageal Reflux Disease (GERD)
This is a cross-sectional study of symptom burden and clinical management. A subset of patients who have attended the Primary Care (PC) office with reflux symptoms during a retrospective period of 4 months (Index Visit) are invited to complete health survey questionnaires and partake in a subject-physician/study nurse interview (Visit 1), in order to assess the type, intensity and frequency of GERD symptoms at both visits and describe the treatment provided. Additionally, the impact of GERD on subjects' life, productivity and willingness to pay for GERD symptom relief will be explored. This design will give a "real-life" clinical practice picture in a representative population of PC doctors and subjects.
This study looks at the effect on basal and pentagastrin-stimulated acid output of 40 mg Esomeprazole (Nexium) administered orally and intravenously as a 15-minute infusion to people with symptoms of Gastroesophageal Reflux Disease (GERD)
This study includes patients with sleep disturbances associated with gastroesophageal reflux disease (GERD) and has 3 treatment arms. Patients will receive only one of the following treatment arms: esomeprazole 20 mg once daily, esomeprazole 40 mg once daily, matching placebo once daily. The relief to the sleep disturbances will be assessed.
Although the symptomatic and epithelial (histologic and endoscopic) response to antireflux therapy are well known and extensively studied, little is known of the genetic events occurring in response to proton pump inhibitor therapy. Preliminary data from our laboratory has shown, for example, that COX-2 expression is not only elevated in patients with gastroesophageal reflux disease but also can be correlated with pathologic esophageal acid exposure on 24 hour pH monitoring. Similar studies have suggested that antireflux surgery may normalize COX-2 gene expression. In contrast studies following ablation of dysplastic Barrett's epithelium have shown persistence of genetic changes associated with altered cellular function, despite the return of the histologic appearance to normal. Several key mediators of inflammation, metaplasia (Barrett's) and neoplasia have now been well characterized and shown to be important factors in the pathogenesis of esophageal injury. It is likely that successful antireflux therapy returns altered expression of these mediators toward normal although this hypothesis remains largely unexplored. The aim of this study is to investigate gene expression of key mediators of the spectrum of esophageal mucosal injury and the response to antireflux therapy. Hypothesis: Antireflux therapy (proton pump inhibitor and surgical fundoplication) normalizes the expression of genes known to be involved in the pathogenesis of inflammation (esophagitis), metaplasia (Barrett esophagus) and neoplasia (adenocarcinoma).
The purpose of this study is to collect post-marketing data on patient outcomes and satisfaction following treatment with the Plicator™. The outcomes will be tracked through analysis of patient Quality of Life (QoL) questionnaires and medication use. The QoL and medication use questionaires will be administered and documented twice before the procedure and then again at outlined intervals following the procedure. Additionally, financial measures will be evaluated (i.e. pre-procedural and procedural time and costs, staffing/personnel needs during procedure, anesthesia and related costs, recovery time and associated cost, etc.) and post-procedure GERD-related medical history questionnaires will be completed. This post-market evaluation is a multi-center study design using the NDO Surgical, Inc. Plicator as the treatment device. Treatment efficacy will be evaluated by comparing QoL and medication use before and after treatment with the device. Patient follow-ups will be completed at 1 week and at 6, 12, 24, 36, 48 and 60 months post treatment.
Barrett's esophagus (BE) is a condition that often occurs in patients who have had GERD for a long time. The researchers are interested in BE because it can sometimes become a cancer in the esophagus. The way that we currently diagnose BE is by performing an upper endoscopy and looking for a change in the color of the esophagus. This color change may represent BE. If the doctor sees this, he/she may take biopsies of this area. Studies have shown that making the diagnosis of BE can be hard to make. One of the reasons why this may be is because doctors may interpret what they see differently during the procedure. In other words, they may see an esophagus that appears normal in color or abnormal in color. The purpose of this study is to compare two doctors' impressions of the appearance of the esophagus during a single endoscopy procedure.
The purpose of this prospective, multicenter study was to evaluate the safety and efficacy of endoscopic full-thickness plication for the treatment of symptomatic gastroesophageal reflux. Sixty-four patients were enrolled and underwent endoscopic full-thickness plication. All patients received a single implant/plication. No repeat plication procedures were performed. Primary efficacy in this study was measured by the percent reduction in post-procedure GERD symptoms as evidenced by analysis of the GERD-HRQL (Health Related Quality of Life) questionnaire. Secondary efficacy outcomes included post-procedure reduction in anti-secretory therapy, improvement in quality of life questionnaires, reduction in distal esophageal acid exposure, and improvement in esophageal manometry. Patient follow-up assessments were completed at 1, 3, 6 and 12 months post treatment.
The purpose of this study was to gather long-term follow-up data on patients treated with the Plicator in a previous open-label multi-center study. Originally, 64 subjects were treated at seven U.S. sites. A subset of those patients were subsequently reassessed via symptom questionnaires in this long-term (60-month) follow-up analysis. The initial open-label study was completed and officially closed at the completion of 1-year follow-up. This current study was designed to collect long-term follow-up data on previously plicated subjects all of whom were recruited de novo from the original study population. Study endpoints were prospectively defined. The primary study objectives were to assess: reduction in GERD symptoms through analysis of the GERD Health Related Quality of Life (HRQL) questionnaire and the Gastrointestinal Symptom Rating Scale (GSRS); reduction in use of GERD medications, and change in overall physical and psychological health as measured by the Short Form Health Survey (SF-36).
The purpose of this project is to test how safe and how well AST-120, an investigational product, works in treating too much acid in the stomach. Patients will be randomly assigned to one of two groups, AST-120 or a placebo for the first four weeks of the study. The patients will be switched to the other group (AST-120 or placebo)for the following four weeks.
