Filter by:This clinical trial was designed to evaluate the functional and safety effects on dyspeptic symptoms compared to the placebo when ingested with EDL (Extract of Dolichos lablab Linne) in adults who complain of dyspeptic symptoms.
Functional dyspepsia (FD) is a common digestive system disease in clinic. Although it has not reached the level of life-threatening, it seriously affects the quality of life of patients. The pathogenesis of FD mainly involves gastric motility disorder and visceral hypersensitivity. At present, there are gastric motility promoting drugs and gastric acid inhibiting drugs, but they can not achieve satisfactory therapeutic effect. Traditional Chinese medicine has a good clinical effect on FD, but the specific mechanism is not clear. With the gradual deepening of intestinal flora research, it provides a useful tool for elucidating the mechanism of action of traditional Chinese medicine compound. The role of intestinal flora in the pathogenesis of FD, especially in the pathogenesis of symptoms, has not been studied, and the mechanism of Spleen-strengthening and motility-promoting effects of Xiangsha Liujun has not been studied from the perspective of intestinal flora. In this study, 16S rRNA high-throughput sequencing technology was used to observe the difference of intestinal flora between FD patients and normal people, and then to observe the effect of Xiangsha Liujun on intestinal flora of FD patients. The aim of this study was to explore the role of intestinal flora in the pathogenesis of FD and to elucidate the therapeutic mechanism of Xiangsha Liujunzi by regulating intestinal flora of FD patients, so as to provide support for follow-up clinical and experimental studies.
A 13 weeks randomized, double-blind and placebo parallel-controlled trial will be conducted to evaluate the clinical efficacy and safety of Zhizhu Kuanzhong Capsule in the treatment of functional dyspepsia-postprandial distress syndrome.
The purpose of this prospective cohort study is to compare upper GI symptoms and endoscopy findings in Canada with Japan and Iran, and correlate this with the upper GI microbiome. The investigators plan to recruit 500 new patients referred for upper GI endoscopy in Canada (McMaster University) and 500 in Japan (Tohoku University Hospital) and 500 from Iran (Tehran University of Medical Sciences). Written consent will be obtained from all participants. Patients will complete three symptom questionnaires and a demographic one before endoscopy. Then saliva collection device will be applied for collecting saliva and microbiota from the oral cavity. Esophagogastroduodenoscopy (EGD) will be performed thereafter and brushing of the esophagus, stomach, and the duodenum will be done using a sterile sheathed brush (one for each site) to sample collect gut microbiota and gastric biopsies will be done for assessing H.pylori status. In addition, a group of these patients will undergo measurement of nitrate reductase activity (NRA) in their oral cavity. This will be done on twenty erosive gastro-esophageal reflux disease (GERD) patients, twenty non-erosive GERD patients, and twenty patients without any endoscopic or clinical GERD. This latter part of the study will be done at the Canadian and Iranian sites only. Bacterial community profiling of the 16S rRNA gene will be carried out using paired end reads of the V3 region. Triplicate amplifications will be pooled for 150 or 250 nt paired-end Illumina sequencing in the McMaster Genome Center. For specific substudies analysis of the mycome will also be carried out.
This trial aims to evaluate the clinical efficacy and safety of Zhizhu Kuanzhong Capsule in the treating patients with functional dyspepsia postprandial distress syndrome(FD PDS). Half of participants will receive Zhizhu Kuanzhong Capsule,while the other will receive a placebo.
Functional dyspepsia (FD) is a common functional gastrointestinal disorder characterized by upper abdominal discomfort/pain and/or symptoms of meal-related fullness/satiety. There is currently no definitive therapy that is beneficial for all FD patients. Accumulating evidence suggests efficacy of tricyclic antidepressants (TCAs) in FD. However, no firm conclusion can be drawn currently due to the relatively small amount of studies and large heterogeneity between studies. In addition, TCAs are often associated with side effects, which occur early after initiation of therapy preceding the therapeutic effect and often result in discontinuation of the therapy. These side effects are related to drug metabolism, which depend on polymorphisms of the cytochrome P (CYP) enzyme system. It is therefore hypothesized that pre-treatment assessment of CYP genotype and subsequent exclusion of abnormal metabolizers limits the occurrence of side-effects and as such improves compliance and efficacy.
In up to half of patients seen by gastroenterologists, routine examinations fail to find an underlying organic, systemic, or metabolic disease that readily explains the symptoms. These patients are referred to as patients with disorders of gastrointestinal function, of which functional dyspepsia (FD) is one of the most common. Despite intensive research to investigate various pathophysiological mechanisms of this disease, the pathogenesis remains obscure. The investigators recently demonstrated increased duodenal permeability in FD patients, as assessed by mounting routine endoscopic duodenal biopsy specimens into Ussing chambers to measure transepithelial electrical resistance and passage of a paracellular fluorescent probe. Impaired intestinal barrier function can lead to increased uptake of luminal substances which can induce an immunological response in the mucosa. Interestingly, using transmission electron microscopy (TEM) in duodenal biopsies, the investigators recently observed the presence of a yet to be identified microorganism inside the epithelium and the lamina propria of a subset of FD patients (unpublished observations), suggesting increased translocation of microorganisms. The aim of the project is to investigate whether FD patients display increased translocation of microorganisms in duodenal biopsies. The investigators will also test the effect of bile acid on translocation of microorganisms and therefore include 20 FD patients and 20 age- and gender-matched healthy volunteers in this study.
