Active clinical trials for "Gastroesophageal Reflux"

To capture safety and efficacy when Nexium are administered to pediatric patients in clinical practice after launch

Recently the relationship between intragastric pressure (IGP) and reflux events after a meal was investigated, both in gastro-esophageal reflux disease (GERD) patients and in healthy volunteers. Ingestion of a meal was accompanied by a drop in IGP. However, the magnitude of this drop varied and was inversely correlated with the number of transient lower esophageal sphincter relaxations (TLESRs) and the number of reflux events, both in patients and in healthy volunteers: a smaller meal-induced drop in IGP was associated with a higher rate of reflux events and vice versa. This finding suggests that a smaller meal-induced drop may act as a trigger for reflux. It has been demonstrated that bitter administration leads to a smaller meal-induced drop. Therefore, bitter can be a dietary trigger for TLESRs facilitating the occurrence of symptoms of GERD. To evaluate this hypothesis, the researchers will study the relationship between bitter and the occurrence of TLESRs and reflux events in healthy volunteers. Additionally, it has been demonstrated that administering bitter also influences the concentration of motilin. Therefore, the research team will also measure the concentration of motilin to investigate whether changes in motilin concentrations can influence the number of TLESRs, via a change in gastric tone.

In view of the high incidence of GERD among seafarers and its continuing impact on the life quality of seafarers, it is necessary to use preventive treatment. At the same time, because both mental and psychological factors and changes in intestinal flora may play a certain role in the development and treatment of GERD, this project intends to take the seafarers involved in this scientific expedition as the participants to explore the effect of PPI discontinuous therapy in preventing gastroesophageal reflux disease of seafarers, a special occupational group and the changes in the mental and psychological status and intestinal flora of this group of people after PPI therapy.

The purpose of this study to assess efficacy of SE endoscopy in the detection of MCE in dyspeptic patients with or without GERD diagnosed by GerdQ or by endoscopy + PHM and in normal volunteers.

Background: Proton pump inhibitors (PPI) are effective for treating gastroesophageal reflux disease (GERD). However, they may be associated with an increased risk of gastrointestinal and respiratory tract infections. Aim: To determine if Lactobacillus GG (LGG) is an effective adjunct to PPI for reducing the risk of gastrointestinal and respiratory tract infections in children with GERD. Study design: Randomized, double-blind, placebo controlled trial.

Gastroesophageal reflux disease (GERD) has been reported in up to 85% of all infants born prematurely, and has been associated with a wide range of symptoms. These include irritability, pauses in breathing, heart rate drops, declines in oxygen levels, chronic lung disease, and delays in growth and development. A novel approach to the mangement of GERD in infants is the use of an abdominal band, applying gentle pressure and possibly reducing the reflux of acid from the stomach. The purpose of this study is to evaluate the impact of a swaddle blanket with an abdominal band insert on the incidence of infant apnea, bradycardia, oxygen declines, and pH (acid) changes.

High Resolution Manometry (HRM) is a new advance in oesophageal measurement that permits the acquisition of pressure data through the entire length of the oesophagus over time via closely spaced sensors that continuously record the motor activity of the oesophagus. This allows not only contractile pressure to be measured, but also the coordination (proximal-distal) of contractions and the development of effective intra-bolus pressure (the force that drives bolus movement). The study hypothesis is that (1) there will be a progressive increase in peristaltic pressure and decrease in velocity as the subjects move from the upright, through the supine to the upside down position and (2) the increase in pressure will be most evident in the mid-oesophagus at the transition zone between the striated and the smooth muscle contractions.

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 goal of this study is to describe the clinical presentation, indications, and operative treatment as well as assess the morbidity, mortality, and overall performance of revisional Roux-en-Y gastric bypass (RYGB) after either failed or functional antireflux surgery "ARS" in obese patients. With such information, we hope to determine which features might assist us in advancing our knowledge about Gastro-Esophageal Reflux Disease "GERD", the best option for primary ARS, and mechanisms of failure in the obese population as well as in identifying predictors of outcome after revisional surgery in this population.

The aim of this study was to evaluate the effect of 14 days treatment with Pantoprazole 40 mg and 20 mg on gastroesophageal reflux disease (GERD) related symptoms in a large patient population.
