Active clinical trials for "Gastroesophageal Reflux"

By affecting the gastroesophageal pressure gradient, obesity predisposes to reflux of gastric contents. The investigators hypothesized that the loss of weight will decrease this gradient and as a result decrease the severity and frequency of GERD symptoms. GERD negatively affects health related quality of life. Since loss of weight may decrease gastroesophageal reflux, the investigators hypothesized that it obesity contributes to poor quality of life in GERD subjects and losing weight should also favorably impact and improve quality of life in GERD patients.

Silastic rings have been used around the gastric pouch in order to promote better weight loss after Roux-and-Y gastric bypass surgery ( RYGBP). However the investigators have shown that some patients developed gastroesophageal reflux disease after RYGBP in a previous study. The investigators hypothesized that the use of a silastic ring may play a role in promoting GERD after this operation.

The objective of this study is to design and use a novel, minimally invasive mucosal impedance (MI) technology to inexpensively and accurately test mucosal health in suspected gastroesophageal reflux disease (GERD) and nonerosive reflux disease (NERD) patients as compared to those without GERD.

Patients with gastroesophageal reflux disease (GERD) are either treated for 4 weeks with a standard dose (20mg) of omeprazole, a drug of first choice, or by an individualized dosing (20 or 60mg/day) according how fast the patient can metabolize (eliminate) the drug. The individual elimination capacity is genetically controlled and therefore all patients will be genotyped prior to therapy.

The purpose of this study is to determine which COPD patients have GERD and if COPD patients with GERD treated with high dose lansoprazole for 1 year decreases the frequency of COPD exacerbations compared to the previous year without treatment.

Obesity has become a significant health problem in Canada. It is known to be a risk factor for many diseases, including Gastro-Esophageal Reflux Disease (GERD). When medical efforts to lose weight fail, patients often consider bariatric surgical procedures as the next step. The two most common bariatric procedures performed are Roux-en-Y Gastric Bypass (LRYGB) and Laparoscopic Sleeve Gastrectomy (LSG). The gold standard for diagnosing GERD is Esophageal pH monitoring, as it is the most objective method to document the reflux, assess the severity and monitor the response to treatment of the disease. In the last few years LSG has gained in popularity due to its simplicity and short operative time. Currently the comparison between bariatric surgery and GERD symptoms is very one sided. There are significant numbers of studies with conclusive results that state that LRYGB has a positive effect on GERD symptoms, however there is little evidence that states the same about LSG. This means that the relationship between LSG and GERD is inconclusive. An objective evaluation of GERD using 24 hour pH monitoring and validated CRFs at different follow up time points will contribute greatly to our understanding of what this relationship might be.

More than 40% of patients with gastroesophageal reflux disease (GERD) experience uncontrolled, chronic symptoms. This proposal aims to improve symptom control for patients with GERD, by developing a mobile health (mHealth) Question Prompt List (QPL) intervention that helps patient ask questions with his/her physician about GERD. The first aim is to gather feedback about daily challenges of living with GERD. The second aim is to gather feedback on the prototype app. The third (primary) aim of this project is to develop the mHealth application and measure differences in patient activation when used compared to standard of care.

Background/Aims: Tegoprazan is a novel potassium-competitive acid blocker that has a fast onset of action and can control gastric pH for a prolonged period, which could offer clinical benefit in acid-related disorders. The investigators aimed to evaluate whether tegoprazan would be more effective in controlling symptoms than placebo in patients with laryngopharyngeal reflux disease (LPRD). Methods: This double-blind, randomized, placebo-controlled trial randomly assigned 35 patients suffering LPRD symptom to two groups: Tegoprazan50mg once daily and placebo. The primary end point was complete resolution rate of LPRD symptoms after 8-week medication, and the secondary endpoints were complete resolution rate of LPRD symptoms after 4-week medication, change of reflux symptom index (RSI) and reflux finding score (RFS) from baseline at 4- and 8-week medication.

The study titled "Effectiveness of Modified Diaphragmatic Training for Improving GERD-Q Score, Diaphragmatic Excursion, Maximum Inspiratory Pressure and Lung Function in Adults With Gastroesophageal Reflux Disease After Covid-19: a Single-blinded Randomized Control Trial" is a clinical trial that aimed to investigate the effectiveness of 4 weeks modified diaphragmatic training (MDT) compare with standard diaphragmatic training for improving GERD-Q score, diaphragmatic excursion, maximum inspiratory pressure, and lung function in adults with gastroesophageal reflux disease (GERD) after COVID-19. The trial was single-blinded and randomized, and it included a total of 50 participants. The results of the study showed that MDT was effective in improving GERD-Q score, diaphragmatic excursion, maximum inspiratory pressure, and lung function in adults with GERD after COVID-19.

The purpose of this study is to determine the effect of vonoprazan compared to esomeprazole for preventing heartburn symptoms over a 4-week treatment period in participants who have a partial response to treatment with esomeprazole.
