Filter by: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 1. 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 2. 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.
This study will establish a registry for participants with eosinophilic esophagitis (EoE) and create a research resource that will provide further insights into EoE.
The primary objective is to assess whether the risk of gastric cancer is increased in pantoprazole users compared to users of other proton pump inhibitors.
To investigate the efficacy and safety of PARIET twice daily (b.i.d.) in patients with Proton Pump Inhibitor-resistant reflux esophagitis
Patients with severe acid reflux and/or Barrett's esophagus are recommended to take Proton pump inhibitors (PPIs)indefinitely to prevent complications such as strictures or the development of a type of esophageal cancer. Recently, some studies suggested that taking these medications on a long-term basis may affect the bone. Therefore, it is important to learn whether these medications may lead to accelerated bone loss so that effective preventive measures can be developed for patients who require these medications for acid-related conditions. Several studies reported that patients receiving PPIs for many years may have increased risk of hip fractures. However, it is unclear whether this is because the PPIs cause reduced bone density or whether the increased risk of fractures has nothing to do with PPIs and is because patients who require PPIs have other illnesses that cause the increased fractures. The purpose of the study is to learn how bone structure and bone mass change after long-term PPI use.
RATIONALE: Manuka honey may prevent or reduce esophagitis-related pain caused by chemotherapy and radiation therapy. It is not yet known whether Manuka honey is more effective than standard care in preventing pain. PURPOSE: This randomized phase II clinical trial is studying Manuka honey to see how well it works in preventing esophagitis-related pain in patients receiving chemotherapy and radiation therapy for lung cancer.
Confocal laser endomicroscopy enables in vivo microscopic imaging within the mucosa layer of the gut at a subcellular resolution. Various studies have addressed the potential of endomicroscopy for the in vivo diagnosis of esophageal squamous cell carcinoma, Barrett´s esophagus and esophageal adenocarcinoma. Currently, there is only one case report from our group who noted the utility of endomicroscopy for the in vivo diagnosis of eosinophilic esophagitis. The purpose of this study is to determine whether endomicroscopy is effective for the in vivo diagnosis of eosinophilic esophagitis.
GERD is a common condition in the western world. In most cases, the diagnostic is established by good response to empiric proton pump inhibitor (PPI) therapy. When the patient symptoms are refractory to therapy, multiple invasive tests are available. The results of those tests (EGD, manometry, Ph monitoring and impedance) are clues that the physician use together to establish the diagnostic. No test however can be use alone because of their poor specificity and sensitivity. Recently, microscopy has been used to detect dilated intercellular space in between distal esophageal cells tissue; unfortunately this marker again failed to diagnose GERD. In search of more sensitive and specific markers of GERD, we propose to assess if acid exposure affects: 1) gene and proteins expression in the esophageal/post-cricoid area tissue; and 2) local impedance of the mucosa. The secondary aim of this proposal is to determine if correlation exists between the two approaches.
There is currently no reliable, noninvasive biomarker for eosinophilic esophagitis (EoE), a chronic allergic diseases characterized by significant infiltration of eosinophils in the esophagus. Because eosinophils release nitric oxide, levels of exhaled nitric oxide (FeNO) are used routinely for guiding treatment in subsets of patients with asthma. FeNO levels are also elevated in immunological diseases that do not involve the airways. The investigators hypothesize that patients with EoE have elevated nitric oxide concentration in their exhaled breath and that changes in FeNO levels could be used to measure disease activity. The objective of this study is to determine the feasibility of using FeNO as a noninvasive surrogate marker for EoE disease activity. The investigators propose to measure serial exhaled nitric oxide (FeNO) levels on a group of patients with confirmed EoE, before, during and after the course of topical corticosteroid therapy to determine whether the level declines from pre-treatment level in individual patients.
This will be a randomised, double blind, placebo controlled, parallel group evaluation of the effect of OC000459 given orally for eight weeks on active eosinophilic esophagitis.
