Active clinical trials for "Gastroesophageal Reflux"

Gastroesophageal reflux disease (GERD) is diagnosed on the basis of characteristic reflux symptoms (i.e. troublesome heartburn and/or acid regurgitation). Empirical therapy without diagnostic endoscopy is suggested for those GERD patients presenting without alarm symptoms in Western countries. Whether such "treating instead of testing" strategy should be applied in Asia, an area with higher prevalence of Helicobacter pylori and gastric cancer, remains uninvestigated.

Gastroesophageal reflux disease (GERD) is a common disorder in Asia that includes erosive and non-erosive counterparts. The evaluation of intra-esophageal damage is of paramount importance because patients with erosive and those with non-erosive GERD have distinct manifestations and prognoses. Although proton-pump inhibitor (PPI) is the treatment of choice for erosive patients with excellent therapeutic response, the majority of reflux patients can be classified with non-erosive reflux disease (NERD).Narrow-band imaging (NBI) is a novel, noninvasive optical technique that adjusts reflected light to improve the contrast of capillary patterns compared with conventional illumination. Based on the standard procedure of sequential conventional white-light, NBI, and magnified NBI, the investigators have validated the reliability of the diagnostic testing. The investigators will also enroll NERD patients to test their therapeutic response to rabeprazole. The investigators can find out the best strategy to identify the PPI responder.

The purpose of the study is to provide data on the GERD prevalence as percentage of patients with upper GI symptoms that are identified with GERD using the GerdQ Questionnaire. Furthermore the study aims to estimate GERD prevalence in patients based on their symptoms as they respond to a physician's questionnaire, to observe possible variations between the two methods (physicians' symptom rating and GerdQ), to objectively measure treatment response and to identify the percentage of patients that may require alterations of their treatment. Finally, to describe the impact of GERD symptoms on work productivity.

A questionnaire composed of items addressing psychological, emotional and social aspects of GERD is developed for Chinese population. We plan to conduct a validation study on this novel disease-specific quality of life (QoL) instrument. This study aims to evaluate various indicators of validity and reliability, which include criterion validity, test-retest reliability, responsiveness, internal consistency reliability and discriminant validity. After initial pilot testing of face validity and content validity, two hundred GERD patients from the gastroenterology and ulcer clinics of cluster NTE hospitals will be invited to complete a revised 18-item version of GERD-QOL questionnaire. The data from GERD QOL will be evaluated using exploratory factor analysis to identify appropriate items and domains and the internal consistency of the domains will be determined and further refinement of questionnaire will follow. 100 GERD patients will complete GERD-QOL, SF-36 health survey and the visual analog scale (VAS) questionnaire for criterion validation. 100 GERD patients with stable symptom profile will repeat GERD QOL two weeks after the first administration for evaluation of test-retest reliability. Another 26 patients who are receiving maintenance acid suppressive therapy and in remission of symptom will be recruited as controls for comparison with active reflux patients. The ability to distinguish active patients from controls in remission is known as discriminant validity.

Gastro-esophageal reflux disease (GERD) is a condition characterized by reflux of stomach contents causing troublesome symptoms and complications. Typical symptoms include heart burn (a retrosternal burning sensation), regurgitation (perception of flow of refluxed stomach content into the mouth or hypopharynx) and chest pain. As per recently published global guidelines (2017) by World Gastroenterology Organisation (WGO), the presence of heartburn and/or regurgitation symptoms 2 or more times a week is suggestive of GERD. Global burden of GERD in general population is approximately 1.03 billion, the prevalence of GERD varies geographically, with the highest prevalence of 19.55% in North America while in Asia, the estimated rate is 12.92%. However the data regarding the prevalence of GERD in intensive care unit (ICU) population is not yet established; which is expected higher after recovery from their current acute illness. In a healthy individual, several factors contribute to the prevention of reflux and to minimizing esophageal acid exposure: lower esophageal sphincter (LES) pressure, the diaphragmatic crura, gravity, esophageal peristalsis, salivary bicarbonate and the integrity of esophageal epithelium. But in critically ill these factors are compromised leading to high incidence of GERD. Interventions commonly used in managing critically ill patients such as sedation, presence of an endotracheal tube, mechanical ventilation, enteral tube feedings, positioning, and medications, along with specific patient characteristics and comorbid conditions contribute to an increased risk for GERD in this population. GERD results in various symptoms which has impact on quality of life. Various reliable and validated generic and disease specific instruments are available to measure symptom severity of the disease. In the present study, among GERD patients, commonly and freely available GERD-Health-related quality of life (GERD-HRQL) score will be used which is a disease-specific instrument. This observational study will screen and enroll adult patients who survived at the time of ICU discharge.

Title: Inter-rater reliability of the reflux finding score based on endoscopic laryngeal findings in the diagnosis of laryngopharyngeal reflux disease Participants: Voluntary participants after invitation among members (a total of about 40 gastroenterologists) of Gangwon Branch of Korean Society of Gastrointestinal Endoscopy and an otorhinolaryngologist Primary endpoint: Interrater reliability (Kappa coefficient) on the sum of reflux finding score more than 7 points between an otorhinolaryngologist and gastroenterologists (7 points means the cut-off value for the diagnosis of laryngopharyngeal reflux disease) Secondary endpoint: Agreement (%) on 8 items of reflux finding score for laryngopharygeal reflux among gastroenterologists

This is a mechanistic research study to evaluate the relationship between cough, reflux, and aspiration in patients with systemic sclerosis (scleroderma).

The Anti-Reflux Surgical Study has been established to: Collect data about anti-reflux surgical treatment options (magnetic sphincter augmentation and Fundoplication) in everyday clinical practice Track the clinical course of patients from pre-operative assessment to three years post-surgery
