Filter by:This is a study to assess the efficacy and safety of 8 weeks of treatment with Dexlansoprazole modified release (MR)(60 mg daily and 90 mg daily) compared to Lansoprazole (30 mg daily) in healing subjects with endoscopically proven erosive esophagitis.
The purpose of this study is to assess the efficacy and safety of 8 weeks of once-daily (QD) treatment with dexlansoprazole modified release (MR) 60 mg or 90 mg or lansoprazole 30 mg in healing subjects with endoscopically proven erosive esophagitis.
The purpose of the study is to verify superiority of the lafutidine group over the placebo group and non-inferiority to the famotidine group in terms of endoscopic healing rate of the patients with mild reflux oesophagitis. Furthermore, the followings are compared: The improvement effect in heartburn and other subjective symptoms, and dosing frequency of MALFA ® suspension (neutralizer) as well as incidence of adverse events among the lafutidine 20 mg/day treatment group, the famotidine 40 mg/day treatment group and the placebo treatment group in patients with mild reflux oesophagitis.
The purpose of this study is to decide if controlling stomach acid is related to healing of erosive esophagitis after treatment with esomeprazole magnesium (NEXIUM®) 10 mg and 40 mg once daily.
The goal of this project is to determine the long-term health outcome of children diagnosed with gastroesophageal reflux (GER). We are inviting subjects that were previously followed in the Pediatric GI programs at Massachusetts General and Children's Hospital, Boston. We have compiled a database of more than 300 subjects that completed diagnostic testing for GER in the 1970's, 1980's, and 1990's. Subjects are being contacted initially by mail using a previously approved recruitment letter. Subjects that fail to respond to this recruitment letter are called by phone. In each case, contact information has been abstracted from the Children's Hospital database. Subjects are then given the opportunity to complete a questionnaire either by phone or in hard copy. Subjects receive no compensation for their participation in this study. Subjects will be compared to controls. Controls will complete the same questionnaire as the subjects. Inclusion of potential controls will be determined by a lack of medical history of gastroenterological diseases before the age of 21 and whether the potential control was born within a year of a subject in the study. Controls will receive $25 to participate in the study.
By using combination of the expression of COX-2 and NOS and immunologic reaction in the esophagus with manometry of LES and cruel diaphragm and 24 hr esophageal pH monitoring to investigate the mechanisms and to make a new and more clinically applicable clarification of these reflux diseases will be valuable in the clinical management and prevention. We will perform the following works and complete the objectives: 1) comparing the difference of immuno-inflammatory reactions among NERD, reflux esophagitis and Barrett’s esophagus; 2) the different expression of PGs & COX-2 in functional heartburn, hiatus hernia, NERD, reflux disease and Barrett’s esophagus; determining the subtype of EP receptor (EP1~4); 3) determining and comparing the expression of NOS in the esophagus; 4) investigating the role of ROS in the esophagus; 5) in correlating cytokine, COX-2 and NOS with LESP, TLESR, diaphragm EMG and 24-hour esophageal pH ; 6) the difference of expression of cytokine, atrophic gastritis and Hp in gastric mucosa, in correlating with intragastric acid status, among functional heartburn, hiatus hernia, NERD, erosive esophagitis and Barrett’s esophagus; to determine whether should eradicate Hp in reflux esophageal disease; 7) the effects of lipid peroxidation related immunologic reaction, with relation to COX-2 and NOS, in the inflammatory activity and esophageal carcinogenesis of esophagus; 8) the effects of cytokines, COX-2 and NOS on the apoptosis in these reflux esophageal diseases; 9) integrating immuno-inflamatory reaction, COX-2, NOS with manometry of LES and diaphragm, and 24-hour pH monitoring and intragastric pH to newly clarify GERD into evidence based categories.
We hypothesize that gastric dysrhythmias may predispose the occurrence of gastroesophageal reflux.
