Filter by:This is a feasibility study to assess the utility of magnetically controlled capsule endoscopy in the evaluation of gastroparesis and functional dyspepsia
This is an exploratory neurophysiological study that will determine the impact of non-invasive brain stimulation on autonomic regulation, with a focus on gastrointestinal function. These studies should provide a basis for future brain-based neurotherapeutic strategies in patients with functional GI disorders.
H.pylori is an organism which causes gastric inflammation, peptic ulcer disease (PUD), mucosa associated lymphoid tissue (MALT) lymphoma and gastric cancer. Practical guideline for treatment of patients with dyspepsia and H.pylori eradication recommended the 14-day triple therapy regimen which had curable about 70% by using proton pump inhibitor (PPI) combined with antibiotics including amoxicillin, clarithromycin and metronidazole. Up to date, there has been no evidence about the cure rate for H.pylori eradication with once-daily dose regimen of high dose rabeprazole and levofloxacin based therapy. This research is to study the 7-day and 14-day cure rate of H.pylori eradication treatment with once-daily regimen of high dose rabeprazole-levofloxacin based quadruple therapy.
Acid reduction remains the most common treatment prescribed empirically by pediatric gastroenterologists for children with functional dyspepsia (FD). When acid reduction therapy fails to provide patients with a therapeutic effect, ketotifen and cromolyn, mast cell stabilizers, represent an attractive potential therapy given data implicating mast cells in the generation of dyspeptic symptoms. Although there have been no adult or pediatric studies on the use of mast cell stabilizers in patients with FD, benefit has been demonstrated in adults with IBS and children with eosinophilic gastroenteritis. Additionally, previous studies show mucosal eosinophilia is highly correlated with functional dyspepsia. Our usual current treatment pathway for functional dyspepsia in association with duodenal mucosal eosinophilia is as follows: acid-reducing medication/montelukast → addition of H1 antagonist → addition of budesonide → addition of oral cromolyn. If ketotifen is effective, it offers the advantage of being able to replace both the H1 antagonist and the oral cromolyn at a substantially reduced cost (approximately 10% of the cost of cromolyn alone). This study aims to introduce ketotifen earlier in the treatment pathway to examine its efficacy on children with functional dyspepsia in association with duodenal eosinophilia.
Aims: 1. Evaluate the long-term effect of screening and eradication of Helicobacter Pylori on the prevalence of dyspepsia, and, as secondary outcomes, to assess the effect on dyspepsia related health-care consumption and quality of life. 2. To investigate symptoms of gastroesophageal reflux (GER), dyspepsia and the combination of these conditions and the effect on quality of life, prognosis and dyspepsia-related health care expenditure. Methods: In 1998-99 20.000 individuals, age 40-65 years, identified by their civil registration number, were allocated by a computerized randomized procedure to HP-screening group and control group. All participants received a questionnaire at inclusion, 1-year and 5-year and now again at 12 year follow-up assessing the prevalence of dyspepsia and quality of life. In addition we will obtain information from registers on, comorbidity, use of endoscopies and prescription medication. An economic evaluation is done alongside the randomized trial. The primary unscreened group is invited to HP test (13C-urea breath-test) in order to analyze the effect of HP-screening according to HP-status Expected results: The study will provide information on the long-term effect of HP-screening and eradication in a population. The study will provide information about the long-term effect on incidence of peptic ulcer in an aging population that is likely to have an increased consumption of ASA and NSAID. Furthermore the study will generate knowledge about the long-term prognosis of dyspepsia and reflux in the population (dyspepsia and reflux. Preliminary results from the 5-yr follow-up (13) showed that is has a great influence on quality of life and the dyspepsia-related health care consumption, whether the individual has solely reflux, solely dyspepsia or a combination of both symptoms. Long-term follow-up and further analyses of these findings could have great impact on management and treatment of individuals with symptoms. It is important to focus on groups; in which the symptoms have the greatest influence on quality of life of the individual. This finding has not been displayed in other studies.
Helicobacter pylori colonizes approximately to 50% of the world-wide population. There is an exigency to find routes alternating to control the infection with an ample perspective but without the complications of induction of resistance to antibiotics. Supplement dietetic with Lactobacillus reuteri (L. reuteri) in humans takes to the colonization of epithelium gastric and this, combined with the observation of which L. reuteri has the capacity to inhibit the growth of H. Pylori and its union to the gastric mucosa, indicates the potential that the native human bacteria control and influence in the colonization in humans. The acid-lactic bacteria (in particular the lactobacillus) have been studied by their effects in humans infected with H. Pylori with some success to reduce the load of bacteria Studies using supplements with L. reuteri as much in infected symptomatic patients as asymptomatic with H. pylori showed a clear reduction of the load of bacteria after 4 weeks of use and this was concordant with a reduction in the symptoms associated to the infection.
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.
