Active clinical trials for "Esophagitis, Peptic"

This study plans to learn more about reflux associated laryngeal symptoms, and more efficient ways to diagnose and treat this condition.

Endoscopy is a widely used modality for the diagnosis and classification of Gastroesophageal reflux disease (GERD), and the extent of esophageal mucosal breaks on endoscopy can be assessed. However, there were some limitation in diagnosis of GERD using endoscopy More than half of patients with GERD reveal no visible abnormality on conventional endoscopy, it is possible that minute mucosal changes are underestimated by conventional endoscopy due to the limitation of visual ability In addition of uncertainty in detecting mucosal breaks, uncertainty in describing severity of mucosal injury can lead to inconsistency among interpreters. Interobserver agreement regarding diagnosis and classification of GERD using endoscopy is unsatisfactory to apply daily practice. Thus, the development of a new method to define the intra-esophageal injury for use in daily practice is a worthwhile endeavor and developed, such as narrow-band imaging (NBI), Fuji Intelligent Chromoen-doscopy (FICE) and i-scan. Among them, i-scan technology is the most recently developed image enhancing technology, which consists of three modes of image enhancement, i.e. surface enhancement (SE), contrast enhancement (CE), and tone enhancement (TE). Thus, the investigators examined the hypothesis that i-scan can improve the detection rate of reflux esophagitis and inter-observer agreement between endoscopists compared with conventional white light (WL) endoscopic examination.

Gastroesophageal reflux disease (GERD), with its cardinal symptom, heartburn, is the most common disorder of the esophagus in the West. Comparatively, GERD is less common in Singapore but its frequency in the population is increasing. Although the vast majority of patients with GERD have heartburn and acid regurgitation, GERD can present in atypical ways, including as a non-cardiac chest pain (NCCP). We have previously shown that GERD is a common cause of NCCP in Singapore. Up to 40% of our patients with NCCP had endoscopic esophagitis, abnormal 24-hour pH monitoring results, and/or a positive acid perfusion test. These tests, although diagnostic, are costly, labour intensive, and not always readily available in the primary care setting. A trial of high-dose proton pump inhibitor (e.g. omeprazole 60 mg daily) has been proposed as a simple, safe, non-invasive and reliable means to diagnose GERD in Western patients with NCCP. We have not used the test routinely in our practice. This study will evaluate the use of a short course of esomeprazole, the S-isomer of omeprazole, as a diagnostic test for detecting GERD in patients with NCCP. The hypothesis is that in NCCP patients with GERD, esomeprazole will resolve their symptoms. Consecutive patients diagnosed with NCCP at the National University Hospital, Singapore, will be invited to participate in the study. Eligible patients will be randomly assigned to receive either esomeprazole (40 mg o d) for 14 days, or comparable dose of placebo at a similar schedule for 14 days, in a double-blinded fashion. At the start of the study, all subjects will complete a baseline symptom assessment. Symptoms will be scored on a graded scale based on severity. During the study weeks, each patient will record his/her own daily symptoms. The patient will be assessed again after the 14-day treatment. The primary outcome measure will be the change in symptom score after initiation of treatment.

The exploration of evocative symptoms of esophageal reflux disease or dyspepsia is based on a relatively invasive endoscopic examination, often badly tolerated, and which, in France, is carried out in 50% of the cases under general anaesthesia. The development of a Capsule Endoscopy, of single use, of esophageal exploration (PILLCAM OESO), could allow a painless exploration of the oesophagus, without infectious risk.The aim of this study is to validate the information provided by the Esophageal Capsule Endoscopy compared to upper endoscopy in the screening of patients with gastroesophageal reflux disease or dyspepsia . For that these patients, after being informed and to have given their signed assent, will initially have an exploration by Esophageal Capsule Endoscopy and then, the very same day or within 3 days maximum, a upper endoscopy'. The information provided by the Esophageal Capsule Endoscopy then by the upper endoscopy will be analyzed by investigators different. This study should make it possible to evaluate the parameters of specificity, sensitivity and predictive values of Esophageal Capsule Endoscopy in this indication.

The aims of the study: To evaluate whether the use of a specific TENS technology can improve GERD symptoms and esophageal acid exposure.

A randomized controlled cross-over trial in full-term infants affected by symptoms suggestive of GER, evaluated through a validated questionnaire (Infant Gastroesophageal Reflux Questionnaire Revised). The parents of all of the enrolled infants will be reassured on the benign nature of the condition and will advise to apply lifestyle changes for one week. Than, the patients will be randomized into one of the two sequence treatment groups. (group A: Mg alginate/thickened formula; group B: thickened formula/Mg alginate) for two weeks. Evaluation of symptom scores will be performed at day 0, day 7, day 21 and day 35.

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.

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.

Patients with gastroesophageal reflux disease (heart-burn, acid regurgitation)may benefit from an educational program explaining the medical aspects of the disease, self-management strategies and how to deal with health services. We hypothesized that patients having participated in an educational program would experience an improved quality of life when compared to patients who did not take part (controls).

This open label, non-interventional study is to compare the efficacy of Omepral® tablet and any other treatments excepting proton pump inhibitors (PPIs) for the treatment of various type of acid reflux related symptoms in patients with reflux esophagitis.
