Filter by:The SIMBA Capsule is a small, single-use, ingestible capsule that allows for the non-invasive sampling of small bowel contents using purely mechanical means. The study will compare the microbial and metabolomics analysis from the sample collected with the capsule series, to same-participant symptom questionnaires and stool microbial analysis.
Randomized controlled trial of an exposure-based behavioral treatment (CBT) in adults with functional dyspepsia who meet criteria for avoidant/restrictive food intake disorder (ARFID) with weight loss.
Functional dyspepsia (FD) is one of most common chronic gastrointestinal disorders. Several types of drugs were demonstrated to be effective in reduction or remission of symptoms and severity of FD, including proton pump inhibitors (PPI), Tricyclic antidepressant and prokinetics. However, the clinical course of FD after taking medication-based treatment was unknown. Furthermore, 20-50% patients remained persistent or worsening of dyspepsia symptoms after treatment. Previous studies have suggested psychological factors (eg. anxiety, sleep disturbance) were related to less improvement of symptoms in natural clinical course. However, there is limited evidence in terms of clinical and psychological factors for less improvement in patients receiving medication treatment for dyspepsia.
The goal of this study is to establish parameters of gastric myoelectrical activity and heart rate variability in healthy human subjects and compare and contrast them to those with gastroparesis and functional dyspepsia, at baseline and following taVNS.
This is an observational study in which data from people with functional gastrointestinal disorders who decide on their own or by recommendation of their doctors or pharmacists to take Iberogast Advance are collected and studied. In observational studies, only observations are made without specified advice or interventions. Functional stomach and bowel (or gastrointestinal) disorders are conditions in which the functionality of the gut, mainly the gut muscles or the gut/brain axis, is disturbed. Functional stomach and bowel disorders cause symptoms like heartburn, cramps and 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. Iberogast Advance is already available in German pharmacies without prescription for patients with gastrointestinal disorders such as FD and IBS. It contains herb extracts that work against inflammation, are calming, and protect the mucosa (innermost layer of the gastrointestinal tract). Earlier controlled studies with Iberogast Advance have shown how well it works and how it affects the body. Since Iberogast Advance is only available since October 2020, there is no information on its use in the real-world setting yet. Therefore, the study researchers want to collect data on the use of Iberogast Advance in the real-world setting. To do this, people with long-term and repeated functional gastrointestinal symptoms who purchase Iberogast Advance from participating pharmacies across Germany will be asked to fill out a questionnaire optionally covering 6 weeks of treatment. The participants will take Iberogast Advance as recommended in the product information. The main purpose of this study is to see how well Iberogast Advance works and is perceived in the real-world setting. Participants will record how they experience a change of their gastrointestinal symptoms (assessed single-symptom-based) from start and during 6 weeks of treatment. Researchers will then compare the differences and analyze treatment effects. The researchers will additionally collect information on usage behavior, characteristics of the patients, their symptoms, tolerability and their satisfaction with Iberogast Advance. There will be no required tests or visits with a study doctor in this study. The researchers will collect the results of the patient questionnaires from Jun 2022 to January 2023.
This is a 2-arm, prospective, double-blind, randomized and placebo-controlled study using DLBS2411 at a dose of 250 mg twice daily (before morning and evening meals), for a 4-week course of therapy, for the treatment of patients with functional dyspepsia (FD), and an additional 8 weeks after end of therapy (Week 12) for follow-up visit. The bioactive fraction of DLBS2411 has been proved at cellular and genetic levels to have an antiulcer effect through both suppressing the gastric acidity and enhancing gastric mucosal protection. The anti-secretory effect of DLBS2411 is exerted through the inhibition of H+/K+ ATPase 'pump' as well as down-regulation of the H+/K+ ATPase gene expression, thus suppressing gastric acid secretion; while its cytoprotective defense mechanism works through the promotion of cyclooxygenase-2 (COX-2) derived prostaglandin (PgE2) synthesis, thus promoting gastrointestinal submucosal blood-flow, stimulating secretion of gastric-epithelial mucous and bicarbonate; anti-oxidative activity; and endothelial-nitric oxide (NO) formation. The mechanism altogether demonstrated DLBS2411's protective capacity to the gastric and colon mucosa by promoting mucous synthesis and stimulating mucosal blood flow. Having such mechanisms of action, DLBS2411 is hypothesized to benefit subjects with gastric acid disorders such as in functional dyspepsia, gastro-intestinal reflux disease (GERD), peptic-ulcer, and irritable bowel syndrome (IBS).
This study aims to assess the efficacy and safety of linaclotide in patients with overlapping symptoms of both functional dyspepsia (FD) and constipation-predominant irritable bowel syndrome (IBS-C).
Functional dyspepsia (FD) is a common functional gastrointestinal disease. Several patient-reported outcome questionnaires have been established to evaluate the severity of FD, including Dyspepsia Symptom Severity Index (DSSI), Nepean Dyspepsia Index (NDI), and Short-Form Nepean Dyspepsia Index (SF-NDI). Functional Dyspepsia Symptom Diary (FDSD) is a newly symptom-focused patients-reported outcome measure raised by the Patient-Reported Outcome Consortium's Functional Dyspepsia Working Group. The association of the novel FDSD and other scores-related to FD has not been fully investigated. Furthermore, the severity of FD is varied among different patients. It remains unclear how the moderate and severe FD can be defined by the FDSD.
Functional dyspepsia (FD) is among the most established and common functional gastrointestinal disorders (FGIDs). FD is subdivided into two subtypes based on symptoms: epigastric pain syndrome (EPS) and postprandial distress syndrome (PDS). Based on international guidelines (Asian Consensus and Rome Consensus), a prokinetic, medication which promotes gut movement (such as Itopride) should be the 1st line treatment for the PDS sub-type and a proton pump inhibitor, medication which reduces stomach acid production (such as Esomeprazole) should be the 1st line treatment for the EPS sub-type. However, in the routine practice in Malaysia, proton pump inhibitor is still commonly used as 1st line treatment for FD, regardless of subtypes. This may be one of the reasons why FD continues to be inadequately treated locally and causes poor health-related quality of life (QOL) in FD patients. The purpose of this study is to compare the clinical symptoms and quality of life improvement in patients with functional dyspepsia (FD) after treatment according to international guidelines versus treatment according to routine practice. Adverse effects when managed according to guidelines versus routine practice will also be evaluated.
The investigators conduct a randomized, double-blind, placebo-controlled pilot study to investigate the effects of a combined extract of green tea seed (saponins) and green tea leaves (epigallocatechin-3-gallate) on gastric mucosal protection in adults with functional dyspepsia for 8 weeks.
