Filter by:Functional dyspepsia is a very common medical condition, which occurs in up to 30% of people in the community. However, results of current pharmacological treatment on functional dyspepsia are unsatisfactory. Rifaximin is a minimally absorbed antibiotic that has been used in treatment of non-constipated irritable bowel syndrome (IBS). In particular, bloating and abdominal pain was improved by rifaximin treatment in this group of IBS patients. Whilst there is considerable overlap in symptoms of functional dyspepsia and IBS, the investigators test whether rifaximin is also effective in curing post-prandial distress symptoms related to dyspepsia.
The purpose of this research is to see if there are differences between children who have FD and children without FD in the ability of the stomach to empty food and/or in ghrelin hormone levels before and after eating. Chronic abdominal pain is the most common persistent pain condition in children and adolescents. One of the most often diagnosed types of abdominal pain is functional dyspepsia (FD). FD is abdominal pain or discomfort (e.g., nausea, bloating) in the upper abdomen that does not get better by having a bowel movement. One possible explanation for having FD is a delay in the emptying of food from the stomach, or delayed gastric (stomach) emptying. Failing to empty the stomach quickly enough may result in the feeling of being full and cause symptoms of bloating, nausea, vomiting and pain. Further, hormonal changes occur before, during, or after eating food that appear to impact stomach emptying. One of the hormones that changes with meals is called ghrelin. The relationship between ghrelin and stomach emptying needs to be explored more in children with FD. Better understanding of what causes FD symptoms may help us to improve treatment for this condition.
The efficacy of traditional triple therapy has been decreased to such an unacceptable level as 70% in many areas. The study is based on the hypothesis: the most important factors which influence the effect of Helicobacter pylori (H. pylori) eradication included acid suppression intensity and sensitivity of antibiotics. So the investigators chose dual therapy because it is simple and verified to be useful. Rabeprazole, as a new proton pump inhibitor (PPI), is reported to be less susceptible to the influence of genetic polymorphisms for CYP2C19. So it has a greater and faster acid suppression effect compared to other PPIs. Amoxicillin is one of effective antibiotics to H. pylori with few side effects. The antibiotic resistance of Amoxicillin is no more than 3% in China. The purpose of our trial is to evaluate and compare the efficacy and safety of dual therapy regimens with different doses of Rabeprazole for initial treatment of H. pylori infection.
The purpose of this study is to assess the efficacy and safety of rabeprazole compared to placebo in Japanese subjects with Functional Dyspepsia.
This trial aims to compare the endomicroscopic image quality and sedation efficacy of propofol or midazolam with fentanyl.
Background: Functional gastrointestinal disorder (FGID) is the most common gastrointestinal disease in daily clinical practice. The disease is symptomatic but has no identifiable cause by standard diagnostic tests such as endoscopy. It is characterized by its frequent relapses and thus the disease causes a significant level of stress and anxiety to patients. Due to the complexity and chronicity of the disease, it is believed that appropriate counseling on the nature and management of the disease is necessary to decrease patient's anxiety level and improve quality of life. Indication: Patients who have symptoms suggestive of FGID including non-erosive gastroesophageal reflux disease (NERD), functional dyspepsia (FD) or irritable bowel syndrome (IBS). Aim: To validate the effectiveness of counseling in patients suffering from FGID. Method: Patients recruited to the study will follow the usual management of patients attending the Gastroenterology specialty clinic in Prince of Wales Hospital. Standard blood tests and endoscopy will be performed. Standard medication will be given to the patients for 8 weeks after endoscopy and the patients will come back to the specialty clinic for a final visit. The patient will be given an "on-demand follow up within 1 year" option at final visit. The patient will decide if he/she wants to come back to our specialty clinic to follow up his/her problem within one year. Follow-up after Final Visit Follow-up questionnaires will be mailed to patients 6 months, 1 and 2 years after Final visit. Randomization: All the patients will be randomized into two groups in First Visit: 1) Control group, and 2) Counseling group. Both groups of patients will follow the above protocol, except that 2 extra counseling sessions will be arranged for the Counseling group immediately after visiting the physician.
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.
Fecal calprotectin is a very sensitive non-invasive inflammation marker in the detection of inflammatory bowel disease and, to a lesser degree, has also proven to be useful in adenomatous polyps, neoplasias, and infectious gastroenteritis. Elevated calprotectin levels can also be found in patients with lesion only in the upper gastrointestinal tract. However, the diagnostic value of calprotectin has never been tested in this setting. The aim of the study is therefore to determine the diagnostic value of fecal calprotectin in patients with diseases of the upper gastrointestinal tract.
