Filter by:The purpose of this research study is to learn about whether treating the esophagus with amiloride reduces either the frequency or the time to onset of acid-induced heartburn in patients with nonerosive reflux disease. In particular, we are looking at people who have either had complete relief while using a Proton Pump Inhibitor (PPI) or who have only had some relief of symptoms while on a PPI.
The purpose of this study is to determine if sleep deprivation results in increased esophageal acid exposure in healthy controls and gastroesophageal reflux disease (GERD) patients.
The purpose of this research study is to see if GE reflux events are associated with increasing levels of pepsin in spit samples. Pepsin is a special protein called an "enzyme" that is made only in your stomach. It is not normally found in your throat. Pepsin breaks down food proteins that you eat to form nutritional building blocks that your body can use to grow. An enzyme is a substance that helps break down proteins. Gastroesophageal reflux disease (GERD) is very common in infants and children, but can result in serious health problems if not accurately diagnosed. The investigators currently do not have a definitive test to be used as a standard for diagnosing pediatric GERD. Measurement of pepsin, an enzyme normally produced only in the stomach, has been used as a non-invasive way to detect gastric aspiration (reflux of stomach fluid into the airway) in both adults and children, but using pepsin to detect reflux has not been tested. Since pepsin should not be present in the normal esophagus and respiratory tract, but is always present in reflux fluid from the stomach, the investigators believe that the more GE reflux the investigators detect, the higher the levels of pepsin the investigators see in the fluid collected from the mouth. If patients do not have GE reflux, but have swallowing problems alone in which food or liquid goes into the airway, the investigators expect that these patients will have no pepsin in the fluid collected from their mouth. The investigators will test these hypotheses by measuring pepsin levels from mouth fluid and comparing them with the number of GE reflux events the investigators find using the pH/impedance (MII (multichannel intraluminal impedance)) test. Since the investigators are interested in pepsin levels for all types of reflux - acid and non-acid -the investigators will study children whether or not they are on acid blocking medicines. The investigators will also look at pepsin levels in patients whose pH/MII is normal, but have aspiration alone that the investigators find on a modified barium swallow (MBS) study. The investigators will measure pepsin levels in healthy children with no reflux symptoms and no swallowing problems as the investigators controls. The investigators anticipate that this study will show a positive correlation between GE reflux events and the presence of oropharyngeal pepsin, which may allow us to use pepsin as a way to test for reflux.
The implications of sleep as it relates to the physiology and pathogenesis of a number of diseases has until recently been ignored. With the evolution of sleep laboratories, there is an emerging recognition of the relationship between sleep and various gastrointestinal diseases- in particular gastroesophageal reflux disease (GERD).( 1-5) It seems intuitive that waking/daytime activities or events may affect sleep and that any consequent sleep dysfunction may reciprocally further affect daytime function
Patients with nonerosive reflux disease (NERD) are less responsive to standard treatment with proton pump inhibitors. The hypothesis of this study was that nortriptyline in analgesic doses may decrease heartburn perception and its corresponding cortical activity measured by magnetic resonance image. Therefore, the aim of this study was to assess the cortical representation of heartburn in patients with NERD under treatment with nortriptyline and placebo.
The study is designed to assess the effect and safety of oral administration of VECAM 40/300 administered at bedtime compared to Esomeprazole 20 mg administered 30-60 minutes before dinner, for control of nighttime and daytime HB and other 24 hour GERD symptoms. The rational for the study is based on the contention that VECAM exhibits potent inhibition of acid secretion and because of its mechanism of action, it can be administered at bedtime without food. Such timing of drug dosing will allow effective inhibition of nighttime acid secretion. Because of its mechanism of action, VECAM exhibits improved 24-hour inhibition of acid secretion and hence, its bedtime administration will not compromise its effect during the daytime. This improved control of acid secretion will predictably result in better control of nighttime as well as daytime heartburn (HB) symptoms.
Evaluate a novel method of augmenting a weak Lower Esophageal Sphincter (LES).
Magnetic Esophageal Sphincter implant is intended to reinforce Esophageal Sphincter function in the treatment of Gastroesophageal Reflux Disease (GERD)
A medical device to augment weak lower esophageal sphincter function.
Aims of research project: To identify key features of the gastro-esophageal junction (structure and function) that protects the esophagus from gastro-esophageal reflux investigated by combined high resolution manometry and magnetic resonance imaging. Hypothesis: 1. Functional factors including GEJ function (e.g. sphincter pressure) and proximal gastric distension determine whether or not TLESR occurs; however 2. Structural factors including separation of GEJ anatomy, intra-gastric distribution of the meal and secretions determine whether TLESR is accompanied by no reflux event, gas reflux (belching) or reflux of ingested food and gastric secretion ('true reflux'). 3. Initial findings by descriptive studies in healthy volunteers (study #1) and patients with mild to moderate gastro-esophageal reflux disease (study #2) will be further interrogated by a randomized, double-blind control trial of baclofen in patients with GORD; a medication that inhibits reflux by effects on GOJ function (study #3) .
