Filter by:Selective serotonin reuptake inhibitors increase the level of serotonin. This study will use functional magnetic resonance imaging to examine how subjects with, and without, irritable bowel syndrome patients respond to serotonergic stimulation. Brain activation during emotional and arithmetic tasks and during visceral pain will be measured after serotonergic stimulation using the oral administration of Escitalopram (10 mg). The investigators will further integrate background parameters of the irritable bowel syndrome subjects and healthy controls (such as microbiota composition, genetic markers of serotonergic and inflammatory pathways, intestinal permeability, state of mood and visceral sensitivity) with the responses to the various challenges on the level of functional brain imaging. These responses may reveal a 'footprint' of the individual gut-brain axis function. Analyses of these individual footprints in multiple subjects with and without irritable bowel syndrome may reveal biosignatures characterising certain groups of patients according to specific gut-brain signalling response patterns. These biosignatures may be used to develop an individualised treatment algorithm for irritable bowel syndrome therapy.
Data assessing the long-term bowel dysfunction following low anterior resection is still lacking. The aim of this study is to evaluate late functional results of patients who underwent rectal resection for rectal cancer. This included calculating LARS and Wexner score and identifying possible risk factors of late postoperative bowel disorders.
Psychological therapies are effective in reducing irritable bowel syndrome (IBS) symptom severity and increasing quality of life and are recommended for the management of IBS by guidelines. Evidence appears strongest for the efficacy of hypnotherapy as psychological treatment. However, therapist-led interventions are time consuming and relatively costly. Approaches based on e-health are cost saving and appear more attractive to patients as no visits to a therapist are necessary. Therefore, the investigators plan to conduct a multicentre randomised controlled trial to examine whether the effectiveness of online hypnotherapy is non-inferior compared to individual face-to-face hypnotherapy delivered by a therapist, according to current FDA guidelines. Online psychoeducation will be used as control condition. In addition, the investigators hypothesize that treatment with online hypnotherapy is a more cost-effective therapy than face-to-face hypnotherapy in IBS patients.
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.
Patients with Irritable Bowel Syndrome (IBS) often link their symptoms to foods. Interest in dietary management recently increased, including the use of a gluten-free diet. To investigate relation of gluten-free diet (GFD) and IBS, a randomized, double-blind, placebo-controlled cross-over trial will be carried out in adults (>18) and patients with IBS according to Rome IV criteria. The aim is to assess gluten-free versus gluten-containing diet in IBS patients and Healthy Volunteers.
Vestibulodynia (VBD) is a complex chronic vulvar pain condition that impairs the psychological, physical, and sexual health of 1 in 6 reproductive aged women in the United States. Here, the investigators plan to conduct a randomized, double-blinded, placebo-controlled clinical trial to 1) compare the efficacy of peripheral (lidocaine/estradiol cream), centrally-targeted (nortriptyline), and combined treatments in alleviating pain and improving patient-reported outcomes and 2) determine cytokine and microRNA biomarkers that predict treatment response in women with distinct VBD subtypes. Positive findings from this study will readily translate to improved patient care, permitting the millions of women with VBD, their partners, and their clinicians to make more informed decisions about pain management.
This study is a cross-sectional observational study design that aimed to include 2000 IBS patients. We used several validated questionnaires, to assess IBS characteristics (such as subtype, severity), psychological features (QoL, anxiety and depression) and assess nutritional triggers. Subjects filled in the questionnaire online, and was spread across the Netherlands.
The purpose of this study is find out if we can use simple tests (biomarkers) to tell us if a specific child would benefit most from CBT or from the low FODMAPs diet.
Irritable bowel syndrom (IBS) is a common chronic gastrointestinal disorder that affects 10-20% of the world population. The prevalence of IBS in Norway is between 8% and 25%. The pathophysiology of IBS is incompletely understood, and there is no effective treatment for this condition. Imbalance (dysbiosis) of the gut microbiome has been found in patients with IBS. In the absence of effective method to restore the dysbiosis, transplantation of a microbiome from healthy individuals with well-functioning gut (FMT) to those with IBS has been performed. Two randomized double blind placebo-controlled (RCT) studies have been published recently. Whereas it was reported in one study that FMT reduced symptom and improved quality of life in patients with IBS, FMT had no effect in the other study. In order to clarify these contradictory results, a new RCT study that enrolled larger number of patients is required. In this study, the investigators intend to recruit 170 IBS patients from those attending outdoor clinic at Stord hospital in a randomized, double blind placebo trial. A single healthy donor with well-characterized microbiome is going to be used. The effects on symptoms, quality of life, fatigue as well as dysbiosis before and after FMT are going to be investigated. The possible mechanisms behind the effects if any of FMT such as changes in intestinal stem cells, enteroendocrine cells and local immune defense shall be also investigated. The patients are going to be randomized either to placebo (own faces), 30 g or 60 g of the donor faces in ratio 1:1:1.
Zeolite clinoptilolite is a volcanic mineral from the group of zeolites. The porous structure is associated with a large inner surface. Due to the anionic framework charge, ions (e.g., Pb^2+) can be absorbed or exchanged. The specific Panaceo PMA zeolite is approved as a class IIa medical device for the repair of the intestine inner lining. It is CE certified and complies with the relevant European Union regulations in terms of safety and effectiveness. Zeolite is known for its absorbing properties. Because of these properties and the results of several human studies, it warrants the investigation of possible effects on specific indications in human medicine, e.g. irritable bowel syndrome. The diagnosis "irritable bowel syndrome (IBS)" is according to the ROME Foundation, an US medical society. IBS is a disorder with dysfunction of the bowels, a latent inflammation is discussed. The present study aims to evaluate the following effects in patients with IBS: - Primary endpoint: effect on the symptoms of IBS. - Secondary endpoint: intestinal wall permeability, integrity of the tight junctions as measured by the change in zonulin concentration in the stool. - Further endpoints: - Inflammation parameters and anti-inflammatory laboratory parameters. - Biodiversity of the gastrointestinal microbiome. - histamine-associated parameters. - Constipation as a possible side effect. For this purpose, a double-blind randomized controlled trial (RCT) is realized prospectively in a monocentric outpatient-controlled study. The subjects take the test compound daily (verum, reference substance) for 12 weeks and document the intake of the study-substance, intake of medications, stool-frequency and consistency. They receive "before" and "after" the intervention phase a blood and stool analysis for the determination of parameters for intestinal wall integrity (zonulin) inflammation (hsCRP, interleukin-10, calprotectin), histamine metabolism, microbiome diversity. The pilot study is realized ahead of the detailed planning of a later main study.
