Active clinical trials for "Dyspepsia"

The pathophysiology of functional dyspepsia is still unclear but several peptides have been indicated in the etiological factors in FD. Ghrelin and leptin are involved in regulation of appetite and gut motility and serotonin is a typical neurotransmitter related with sensory and motor functions of gut. On the other hand, transient receptor potential vanilloid receptor 1 (TRPV1) has been proposed to be involved with functional gastrointestinal disorder, and expression of this receptor could be regulated by nerve growth factor (NGF) or glial cell-line derived neurotrophic factor (GDNF). The investigators aimed to determine whether expressions of ghrelin,leptin, serotonin,TRPV1,GDNF and NGF in blood or gastric mucosa of FD patients are different from those in healthy controls, and whether some changes of their expression correlate with certain dyspeptic symptoms. The investigators also investigated the effect of H. pylori infection by comparing their expressions before and one year after H. pylori eradication.

Reflux and dyspeptic symptoms are common affecting 10-20% of the population on a regular basis. Reflux symptoms such as heartburn and regurgitation are caused by the return of acid or non-acid gastric contents into the esophagus. Dyspeptic symptoms are caused by abnormal gastric relaxation (impaired accommodation) or increased sensitivity of the stomach to distension during the meal. The effects of diet on gastrointestinal function are debated and the efficacy of dietary management for digestive symptoms has not been established. Epidemiological studies suggest an effect; however, it is not possible to distinguish the effects of fat intake and total energy (i.e. calorie) intake in this work. This issue has been addressed by small physiological studies. The results show that esophageal acid exposure was related to total calorie intake but not to fat content. In contrast, the number of reflux symptoms was 40% higher after the high-fat than the low-fat meals. Similar findings were found for the relationship between gastric distension, fullness and dyspeptic symptoms by Magnetic Resonance Imaging. Thus, it appears that fat does not cause digestive dysmotility but heightens sensitivity to visceral events and so increases the number and severity of symptoms reported by patients. As yet, these findings have not been confirmed in larger, more representative surveys. Similar to the effects of food, there are inconsistent findings regarding the effects of alcohol on gastro-esophageal reflux (GER) and gastric function. Physiological studies have noted delayed gastric emptying and an increase in reflux events when alcohol is taken with food. However, larger surveys have not confirmed that alcohol triggers reflux or dyspeptic symptoms. The proposed observational, dietary study with cross-over design will assess the independent effects of energy intake (i.e. calorie load) and fat intake on gastric fullness, the number and severity of reflux and dyspeptic symptoms after meals. The effect of alcohol on symptoms after the high calorie, high fat meals will also be documented. The study population of senior academics attending a conference are likely to have a relatively high prevalence of risk factors for gastro-esophageal reflux disease (GERD) being predominantly male, with an older age and a larger waist circumference than average in the general community. This will increase study power and relevance of the findings. The results will provide new information concerning the impact of dietary factors and alcohol on digestive symptoms after meals. This data will inform future guidelines for the dietary management of patients with reflux and dyspeptic symptoms after meals which will be relevant in both primary and secondary care.

Indigestion or dyspepsia is highly prevalent worldwide. Often these symptoms are of benign nature and subside without treatment, or with lifestyle interventions like dietary modifications. Too often, gastroscopy is performed because of dyspepsia. Although this is indicated when malignancy is suspected, in a substantial part of the cases the gastroscopy is not indicated and will not achieve clinically relevant results. It is suspected that gastroscopy is often used for reassurance of patients or as a 'last resort'. Our hypothesis is that adequate education of patients can replace this need for invasive measures. The aim of this study was therefore to reduce the volume of gastroscopies for dyspepsia, by offering patients an e-learning containing educational material on dyspepsia. During the trial, 119 dyspeptic patients, referred for gastroscopy by the GP, will randomly be divided into two groups: One group will receive the e-learning instead of gastroscopy (intervention), the other group will receive the gastroscopy (control). After a twelve week follow-up, change in symptom severity, disease specific quality of life and fear of disease will be compared between the two groups.

Background. Dyspeptic patients tolerate smaller meal loads than healthy subjects, but it is not known whether and to what extent symptoms relate to abnormal homeostatic or hedonic components of perception. Methods. Parallel studies in patients with symptoms induced by meals (fulfilling Rome IV criteria of postprandial dyspepsia) and sex- and age-matched healthy subjects. Participants will be instructed to eat a standard dinner the day before, to consume a standard breakfast at home after overnight fast, and to report to the laboratory, where the test meal will be administered 4 h after breakfast. Studies will be conducted in a quiet, isolated room with participants sitting on a chair. Participants will ingest a probe meal up to the level of maximal satiation. The probe meal will be served stepwise (112 Kcal every 5 min). Perception of homeostatic (hunger/satiation, fullness) and hedonic (digestive well-being, mood) sensations will be measured at 5 min intervals 10 min before, during and 20 min after ingestion at 10 min intervals.

Researchers want to learn more about the day-to-day use of Iberogast in people who have functional and motility-related gastrointestinal (stomach and bowel) diseases. Functional and motility-related stomach and bowel diseases are conditions in which the functionality of the gut, mainly the gut muscles or the gut/brain axis is disturbed. Functional and motility related stomach and bowel diseases cause symptoms like heartburn, cramps and u pain of the upper and middle part of the belly, also known as functional dyspepsia (FD), and irritable bowel syndrome (IBS). IBS affects predominantly the lower digestive system and causes symptoms like pain of the belly, cramps, bloating, diarrhea, and constipation. In this study, the researchers want to learn more about Iberogast, a plant-based treatment. Iberogast is available to treat stomach and bowel diseases such as FD and IBS. Earlier studies with Iberogast have shown how well it works and how it affects the body. But, little is known about the day-to-day use of Iberogast and how satisfied patients are who take it. So in this study, the researchers want to learn more about Iberogast including: how well it works in day-to-day use how it affects the body, also referred to as tolerability how it is used day-to-day how safe it is how satisfied patients are who take it To answer these questions, the researchers will collect information from pharmacies in Germany. Patients who get Iberogast from these pharmacies to help treat their gastrointestinal disease will complete a questionnaire before, during and after taking Iberogast. The researchers will use the results from the questionnaires to learn more about: the disease details of the patients who are taking Iberogast the patients' symptoms while taking Iberogast if the patients' symptoms change after taking Iberogast how satisfied patients are with Iberogast if the patients had adverse events An adverse event is any medical problem that a participant has during a study. This study will include patients in Germany who: have functional stomach and bowel symptoms or disorders like FD or IBS take Iberogast to treat symptoms of their stomach and bowel disease are able to complete the questionnaire There will be no required tests or visits with a study doctor in this study. No treatments will be given as part of this study. The researchers will review information collected from patients who have decided for their own or by recommendation of their doctors or pharmacist to take Iberogast. The researchers will collect the results from the patient questionnaires from November 2017 to March 2018.

Brain imaging has shown abnormal brain activations in response to visceral stimulation in patients with the Irritable Bowel Syndrome (IBS) and Functional Dyspepsia (FD). To investigate the possible role of the Nucleus of the Solitary Tract (NTS), the primary relay station in the brainstem for vagal afferents, its activation in IBS and functional dyspepsia patients will be evaluated. Prior to this, an exploratory study in healthy volunteers will be conducted. This will be the first high magnetic field fMRI study (7T) evaluating the possible role of NTS activation in visceral abdominal pain. Moreover, this will be the first pharmacological fMRI study using duodenal capsaicin infusion as a chemical stimulus, which is more physiological than mechano-stimulation in the upper gastrointestinal tract.

To evaluate the efficacy of 4-week lansoprazole (Takepron) therapy for subjective symptomatic improvement in gastroesophageal reflux disease patients with dyspepsia symptoms

The specific aim of the study is to investigate the relationship between the development of dyspepsia and GI dyspeptic symptoms in relation to circulating levels of peculiar GI peptides (such gastrin, pepsinogen and GLP-2) in patients with non-gastrointestinal neoplasm well controlled for emesis.

Food allergy reactions cause various health disorders in sensitive people. These reactions may be IgE-mediated,cell-mediated, energy disturbance-mediated, or a combination of the three. Certain laboratory diagnostic procedures have been able to identify most IgE-mediated or cell-mediated food reactions, but so far there is no test available in traditional medicine to test the energy-mediated allergies and sensitivities. NAET® procedures have been able to identify food substances triggering to energ disturbances in sensitive people causing related health disorders. NAET uses one of the testing procedures called NST (Neuromuscular sensitivity testing).The efficacy of NST-NAET to screen food sensitivity will be evaluated in comparison with one of the well accepted, established, traditional medicine allergy testing known as the IgE-specific antigen test.

This study evaluates four different meals and how they induce gastrointestinal symptoms in children with functional dyspepsia. All subjects will receive each meal and rate their gastrointestinal symptoms during each meal.
