Filter by:There has been recent interest into the potential role of mucosal barrier defects in the pathophysiology of functional gastrointestinal disorders (FGIDs). There has been evidence of increased intestinal permeability in patients of IBS,and abnormal tissue resistance in NERD. Although the mucosa of Functional dyspepsia (FD) patients is endoscopically and histologically "normal," it contains ultrastructural changes, activated immune cells, along with evidence of an increased release of mediators leading to gastric dysfunction. There is now consistent evidence indicating that mucosal barrier defects allow the passage of an increased load of bacteria, antigens and toxins which, in turn evoke activation of mucosal immune responses involved in the FD symptom.
To study the anti free radical & inflammatory effect and safety of Rebamipide in patients suffering of dyspepsia due to chronic gastritis.
The role of Helicobacter pylori infection in functional dyspepsia remains controversial. Several randomized controlled trials in western countries have shown no significant advantage over placebo. But some recent studies in Asian population were different compared to the result of studies in the Western population. At the present time, it seems to be difficult to conclude the efficacy of the H.pylori eradication therapy in patients with H. pylori-infected functional dyspepsia. The investigators hypothesize that eradication of Helicobacter pylori has a sustained global symptom improvement in patients with H. pylori infected functional dyspepsia.
The purpose of this study is to assess efficacy based on Gastrointestinal Symptom score and safety based on the rate of adverse event or laboratory findings of Banhasasim-tang administrated three times a day orally on functional dyspepsia.
The prevalence of functional dyspepsia (FD) is estimated to be 15% of the adult population. FD is commonly described as a condition of chronic abdominal discomfort localized to the upper abdomen. Postprandial bloating, pain, nausea, vomiting, belching, and early satiety are common symptoms of the FD patient. FD is defined by >12 weeks of symptoms, which need not be consecutive, within the preceding year consisting of a) persistent or recurrent dyspepsia and b) an absence of organic disease after a gastrointestinal endoscopy or x-ray series. FD is therefore considered a disorder of function because no mucosal pathology is seen in these patients, as in patients with other functional disorders such as irritable bowel syndrome (IBS) and fibromyalgia (FM). There is a remarkable degree of overlap among these three disorders. These 3 disorders share the finding of hypersensitivity and the symptom of postprandial bloating to suggest the possibility of a common origin.
Functional dyspepsia is one of the most common digestive disorders. The pathophysiology of functional dyspepsia is uncertain. Proton pump inhibitor (PPI) has been recommended as the first line treatment for functional dyspepsia. However, the mechanism of symptom relief is unclear. Most of the previous studies were performed on healthy volunteers who received only a very short course of PPI. The correlation between symptom and gastric emptying is lacking in these studies. Demographic data and anthropometric measurements will be obtained for baseline assessment. Patients are required to complete FGI Screening Questionnaire, Functional dyspepsia symptom questionnaire, gastroesophageal reflux disease (GERD) symptom questionnaire and irritable bowel syndrome (IBS) symptom questionnaire to have a thorough assessment of their GI symptoms. (1) Satiety test and ghrelin profile, and (2)gastric emptying test will be arranged as two individual visits. After baseline investigations, patients will be randomly assigned to either Nexium 20 mg daily or identical looking placebo for 8 weeks. The patients will report their individual dyspeptic symptoms on weekly basis using a self-administered symptom questionnaire. Satiety test and ghrelin profile, gastric emptying study will be repeated at the end of 8-week treatment. Hypothesis: Long-term PPI relieves dyspeptic symptom through acceleration of gastric emptying rate.
The purpose of this study is to evaluate the efficacy and safety of the Chinese prescription Weiqi decoction on Chronic Atrophic Gastritis.
The objective of this trial is to evaluate the efficacy and safety of PDC-339 in the treatment of acute erosive gastritis, using placebo as the comparator.
The modified Lanza scale (Lanza FL, 1984) has been widely utilized to grade the degree of gastritis and duodenitis. However, the inter-rater or intra-rater reproducibility of this scale has never been validated. As a quality improvement program, it is important to study the reproducibility of the scale between different operators and the operators himself. Method: During upper endoscopic examinations, one investigator performed the procedure and the second investigator look at the endoscopic image. The degree of gastritis and duodenitis is graded. The results of the grading are blinded to the other investigator. The endoscopic video is stored for reassessment to determine the intra-rater reliability. The patient identifier is stored in serial number. The investigator will not retrieve the report of the first assessment during the second assessment.
Functional dyspepsia (FD) is one of the most common chronic gastrointestinal disorders affecting humans. Existing therapies for FD are still far from satisfactory and new therapies are constantly being sought. Acupuncture has been used for the alleviation of functional gastrointestinal symptoms in several non-controlled studies. This study aims to investigate the therapeutic efficacy of acupuncture in patients with FD.
