Filter by:There are three main directions for use GerdQ in practice. First of all, GerdQ can be used to diagnose GERD with an accuracy comparable to the accuracy of diagnosis of GERD by the specialist (gastroenterologist). Using GerdQ can evaluate the impact of disease on the patient's life and help in choosing treatment of GERD, as well as direct assessment of treatment efficacy. In connection with mentioned above, this study is devoted to the estimation of possibility to use GerdQ in routine practice of Russian physicians.
The investigators will determine the prevalence of gastroesophageal reflux disease (GERD) in Eosinophilic Esophagitis (EoE) and importantly determine the predictors of response to Proton Pump Inhibitor (PPI) therapy in EoE. Moreover, the investigators will determine the effect of GERD on the location of esophageal eosinophilia.
The aim of this study is to establish a dose-related effect of a selective 5-HT4 receptor agonist compared to placebo on residual symptoms (regurgitation with or without heartburn) in subjects with GERD who have persistent symptoms while on PPI therapy.
A phase III, randomized, open-label, superiority study comparing the incremental product esomeprazole associated with sodium bicarbonate made by Eurofarma and Nexium® in the treatment of gastroesophageal reflux disease. The study will enroll 94 patients in each arm (total of 188 patients).
This is a prospective study to extensively evaluate subjective patient parameters on quality of life, reflux-symptoms, side effects, medication-use and measurements of esophageal manometry and Impedance-pH-Monitoring after Full-Thickness-Gastroplication.
The purpose of this study is to evaluate the impact of gastroesophageal reflux disease (GERD) treatment in primary care setting on symptom control and daily life in symptomatic GERD patients, using both GERD questionnaire and clinical symptoms assessment
Background: Up to 40% of patients who are treated with PPIs for symptoms that are thought to be due to GERD experience only incomplete relief of their symptoms. Those patients are deemed "PPI failures." Esophageal pH monitoring studies have shown that PPI failure rarely is due to persistent acid reflux. Recently, heartburn that is refractory to treatment with PPIs has been described in patients with eosinophilic esophagitis, a disorder of unknown etiology in which eosinophils infiltrate the squamous epithelium of the esophagus, where they cause symptoms and tissue injury. Presently, it is not clear how often eosinophilic esophagitis underlies PPI failure for patients with GERD symptoms. Purpose: To estimate the frequency with which eosinophilic esophagitis is the cause of "PPI failure" in patients thought to have heartburn due to GERD. Methods: Patients referred to the Division of Gastroenterology at the Dallas VA Medical Center for the evaluation of heartburn that is refractory to PPI therapy will be invited to participate in the study. Patients who provide informed consent will have a medical history taken. Women of child bearing potential will have a pregnancy test. The patients' current PPI therapy will be discontinued, and patients will be treated with lansoprazole 30 mg BID for one week. The patient will return to the clinic one week later. Patients who feel that their heartburn has not improved by more than 50% from baseline will have an endoscopic evaluation. During the endoscopic examination, biopsy specimens will be taken as follows: A. Two specimens from the proximal esophagus at 20 cm from the incisor teeth. B. Two specimens from the mid-esophagus at 28 cm from the incisor teeth. C. Two specimens from the distal esophagus, 3 cm above the squamo-columnar junction. D. Two specimens from the distal esophagus, 1 cm above the squamo-columnar junction. E. Two specimens from the second portion of the duodenum (to see if the eosinophilia is confined to the esophagus, or part of a more extensive eosinophilic gastroenteritis). A diagnosis of eosinophilic esophagitis will be made if there is at least one high-power field with >25 eosinophils, or two or more high-power fields with >15 eosinophils. Potential Benefits: This study will provide an estimate on the frequency with which eosinophilic esophagitis is the cause of "PPI failure" in patients thought to have heartburn due to GERD. This has substantial potential importance for patient management.
The purpose of this study is to evaluate treatment in Gastroesophageal Reflux Disease (GERD) patients (aged 18~75) with endoscopically proven GERD treated with AGSPT201 Tablet.
Administration of esomeprazole 20 mg to subjects who still had heartburn after receiving rabeprazole 10 mg once daily for at least 4 weeks will result in statistically significant improvement of heartburn after 8-week treatment.
To the best of our knowledge, there has been no randomized controlled trial to compare double dose PPI therapy with standard one dose PPI therapy for NERD patients. Thus, we hypothesize that a double dose PPI would accelerate and sustain the control of symptom in NERD patients.
