Filter by:The purpose of this study is to investigate the relationship between ear fullness, pressure, and/or pain and laryngopharyngeal reflux, in order to focus medical therapy and improve therapeutic outcomes in this patient population.
The purpose of this study is to find out if people who have non-erosive reflux disease (NERD) have changes the investigators can see with a microscope (called confocal endomicroscopy) that is used during endoscopy (a camera scope evaluation of the inside of your stomach and swallowing tube). Traditionally the investigators have used trials of acid blocking medications (PPIs), endoscopy and measurements of acid in the swallowing tube (the esophagus) to determine if the investigators think acid is causing troublesome symptoms. The medical community believes that these symptoms are due to increased spaces between the cells that make up the swallowing tube. The investigators can directly see those spaces with a new microscope that the investigators can pass through the camera scope. Participants will be assigned to take one of two medications omeprazole and sucralfate (both approved medications for stomach symptoms) to treat their symptoms and record how well the treatment works. The investigators then will look to see if the microscope can predict which medication will work best for patients in the future. The investigators also plan to measure the acid levels in your swallowing tube and do a camera evaluation of your swallowing tube and stomach as this is standard for patients with your symptoms. The investigators will compare the results of those studies to the microscope findings.
Study Hypothesis: This study is designed as an integral part of the development of new or improved features or components of the Bravo® pH Monitoring System and may serve verification and validation purposes. The study population will include symptomatic patients with known or suspected gastroesophageal reflux disease Symptomatic patients will undergo invasive procedure, including Bravo capsule delivery, positioning and attachment. Confirmation of capsule attachment may be done endoscopically. These procedures will serve to evaluate overall system performance in actual clinical setup, for instance: ergonomics and performance of delivery device, capsule transmission etc. Physician may be asked to provide feedback on the procedure and/or document their activities during the procedure.
This superiority phase III study to compare the combination of Pantoprazole and Domperidone with Pantoprazole isolated to the treatment of gastroesophageal reflux disease. The hypothesis is that combination of the two medication at the unique capsule is better to the patients because decrease the quantity of times the patients need to take medicines during the day.
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.
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).
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.
Although laryno-pharyngeal reflux (LPR) and gastroesophageal reflux disease (GERD) differ in symptoms and treatment, they are diagnosed by the same standard 24-hour pH monitoring system which measures liquid reflux in the esophagus. The investigators are evaluating a new 24-hour pharyngeal pH monitoring system by Restech which can measure acid exposure in the airway and can be used specifically for LPR diagnosis. The purpose of this study is to determine whether the Restech device is more effective than standard pH monitoring in predicting the response to proton pump inhibitor (PPI) acid suppression therapy using Dexlansoprazole in patients with symptoms and/or manifestations of LPR.
The purpose of this study is to evaluate the utility of a minimally invasive nasopharyngeal pH probe for the diagnosis of laryngopharyngeal reflux (LPR) in children with airway compromise; to determine whether it is comparable to the gold standard esophageal pH probe in identifying LPR in this population; and to correlate results of pH testing with validated questionnaires. Our hypothesis is that a nasopharyngeal pH probe is equivalent to an esophageal probe in identifying laryngopharyngeal reflux.
The purpose of this research is to address the comparative effectiveness and harm of the therapeutics frequently given to pregnant women and their young infants including antibiotics, tocolytic agents, non-steroidal anti-inflammatory drugs, H2 blockers, and steroids. Our overall hypothesis is that the use of an existing electronic medical record with additional resources for precise data collection and 18 month follow up will successfully address current knowledge gaps in therapeutic effectiveness and relative therapeutic harm. We will use an existing electronic medical record into which detailed healthcare information is entered for over 100,000 newborns each year. These infants will comprise the "Source Cohort". Nested within that database, we will prospectively enroll 10% of the population (10,000 newborns) as the Follow-Up Cohort. The current electronic medical record for the Source Cohort does not capture therapeutic dosing with sufficient precision to conduct comparative effectiveness research sufficient to change medical practice. The proposed research will: 1) ensure accurate data collection through electronic monitoring and real-time quality assurance evaluation in the Source Cohort; and 2) conduct 18 months post-hospital follow-up for neurologic outcomes and disability for the Follow-Up Cohort. We will complete assessments of neurologic outcomes and disability using an interactive web-based system, mail, telephone follow up, and in-person examination.
