Active clinical trials for "Dyspepsia"

Participants experiencing recurrent gastrointestinal symptoms in this double-blind, randomized, controlled trial will receive either a commercially-available probiotic dietary supplement or placebo. The investigators hypothesize that participants in the probiotic dietary supplement group will experience greater improvement in their gastrointestinal symptoms than participants in the placebo group.

This non-interventional, observational study investigates the course of symptoms in patients with functional dyspepsia under treatment with a fixed combination of pepsin and amino acid hydrochloride over a period of approximately 6 weeks. The change of the Gastrointestinal Symptom Score (GIS©) was the primary parameter for the assessment of efficacy and was performed at baseline, after 3 and 6 weeks of treatment respectively. Safety measures included recording of AEs and physical examination as well as measurement of vital signs. The aim was to observe 100 patients during the course of this non-interventional study.

Rome III criteria defined functional dyspepsia (FD) as the presence of symptoms from the gastroduodenal region in the absence of any organic, systemic or metabolic disease that is likely to explain the symptoms. FD can be further subdivided into two diagnostic categories: postprandial distress syndrome (PDS) and epigastric pain syndrome (EPS). Disorders of gastric electric activity and abnormal gastric emptying are probably actively involved in the FD onset. Different noninvasive procedures may be applied in order to evaluate the gastric motor functions such as 13C breath testing and cutaneous electrogastrography. Besides, different gastrointestinal peptides (i.e. CCK, peptide YY, Neurotensin, Somatostatin, Leptin, Ghrelin, Motilin, Gastrin, Pepsinogen I and II) are involved in the control of gastroduodenal motility. Aims of the present study are: 1) to evaluate the GI peptide circulating concentrations, the gastric electrical activity and gastric emptying time by applying noninvasive procedures in patients suffering from functional dyspepsia and 2) to test whether a significant difference exists between the two diagnostic categories of meal-induced dyspeptic symptoms

The purpose of this research is to further study the relationship between gastroparesis (GP) (a condition in which the stomach cannot empty itself of food in a normal fashion) and functional dyspepsia (FD) (frequent symptoms of indigestion that have no obvious cause).

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.

Digestive Functional Disorders (DFD), represent 50% of medical check ups, the symptoms interfere with patients quality of life and generate high health costs. On the other hand, with the worldwide overweight and obesity increase,causing an over production of low-calorie products, which increase the non-caloric sweeteners (NCS) consumption. Hypothesis: A diet without NCS will reduce gastrointestinal symptoms in volunteers with dyspepsia and IBS. Objective: To asses the effect of a diet without NCS, on the gastrointestinal symptoms in patients with dyspepsia and IBS. Secondary Objectives: To compare the effect of a diet without NCS against a diet with NCS on anthropometry, changes in body composition, biochemical parameters, glucose and insulin. To asses the change in the gut microbiota using real-time PCR (polymerase chain reaction) Methodology: it will be an experimental, open, parallel, controlled study lasting 12 weeks, patients with dyspepsia or IBS will be randomized assigned to a diet with or without NCS. Laboratory studies, dietary and symptoms questionnaires, anthropometry measurements and faecal sample will be carried out. Analysis Results: A double data capture will be carried out to minimize errors, for the statistical analysis of using the Statistical Package for the Social Sciences (SPSS) version 25, descriptive statistics will be used to report the baseline data of the volunteers. Using means and standard deviation, the variables of gastrointestinal symptoms will be used a chi-square test and a p <0.05 will be considered significant. Different analyzes will be done to evaluate volunteers with IBS and those with dyspepsia. For the intestinal microbiota analysis, a comparison will be made between the percentages of Firmicutes, Bacteroidetes and Actinobacteria of sample 1 and 2 and a chi-square test will be performed considering a p <0.05 significant

Functional dyspepsia might have impaired gastric mucosal dysfunction and Puyuanhewei may be helpful to improve the symptoms of FD.

Dyspepsia is a common presenting complaint that doctors have to manage and this is true both in the primary and secondary care setting. OGD is a useful test for investigating a variety of suspected upper GI disorders including dyspepsia. However, it is uncomfortable for patients and incurs the risk of intubation and sedation. Capsule endoscopy (CE) is the investigation of choice for diseases of the small bowel. It is safe, non-invasive and well tolerated, the main risk being capsule retention occurring in up to 1-2% of procedures. The investigators wish to undertake a prospective study comparing acceptability and tolerability of MACE and OGD in the investigation of dyspepsia. Patients presenting to general practice or the outpatients department with symptoms of dyspepsia who are referred for investigation are invited to take part in the study. Patients will undergo MACE prior to OGD performed by an endoscopist blinded to the MACE findings. . A comparison of tolerance and acceptance of both procedures will be measured by means of using structured and validated, qualitative questionnaires. The aim is to assess for whether there is a significant difference between the perception and experience of both modalities.

This is a randomized, double-blind, cross-over study in healthy volunteers. In the first part, the duodenum of the participants will be perfused with acid or saline, during which intragastric pressure will be monitored to assess activation of the duodenogastric reflex. After perfusion, duodenal biopsies will be collected to evaluate mucosal integrity. In the second part, healthy volunteers are treated with the mast cell stabilizer disodium cromoglycate or with a placebo during 14 days. Subsequently, the duodenum will be perfused with acid and intragastric pressure and mucosal integrity will be evaluated.

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.
