Active clinical trials for "Irritable Bowel Syndrome"

Longitudinal Investigation of intestinal microbiome, fecal inflammation markers, stress and psychological variables in patients with irritable bowel syndrome and inflammatory bowel disease undergoing gut-directed hypnotherapy (GHT).

Irritable bowel syndrome (IBS) is one of the most common gastrointestinal disorders. It has prevalence in general population of 5-20% and is more common in women and young adults. Despite being one of the most frequent reasons for consultation many patients are undiagnosed. There are no reliable biomarkers. The diagnosis is clinical, based on the Rome III criteria. IBS is characterized by chronic or recurrent abdominal pain associated with changes in bowel frequency and consistency, when other etiologies are excluded. The combination of the Rome III criteria with the absence of alarm symptoms have a sensitivity of 65%, specificity of 100%, 100% positive predictive value and negative predictive value of 76%. Current tests commonly fail to obtain an objective diagnosis, and effective therapies are lacking. There are no specific endoscopic findings that can discriminate IBS patients from healthy patients. Most colonoscopies are performed to rule out other etiologies and in more than 50% of the cases are normal.

The purpose of the survey is to evaluate the safety and efficacy of Irribow and Irribow OD Tablets in post-marketing medical practice and to examine the status of treatment compliance.

The burden of chronic disease is continuing to rise. Even though patients may be in remission or have quiescent disease, several studies have confirmed that symptoms, such as e.g., fatigue, is troublesome. The primary aim of this study is to investigate whether or not there might be an association between levels of vitamin D and the subjective experience of fatigue in conditions, such as inflammatory bowel disease, diabetes mellitus, rheumatoid arthritis and irritable bowel syndrome. Secondary aims is to study both the co-occurence and influence of pain, depression and anxiety.

Consequences of Colon Hydrotherapy plus probiotic intervention on composition of GI microbiota and well being are analysed in subjects claiming GI inconveniences due to Irritable Bowel Syndrome or food intolerances.

The purpose of this study is to determine the amount of linaclotide and its active metabolite (MM-419447) excreted in breast milk after multiple, once daily doses of linaclotide (72 μg, 145 μg, or 290 μg) in lactating women receiving the drug therapeutically.

Chronic constipation (CC) and Irritable Bowel Syndrome with Constipation (IBS-C) are two conditions difficult to manage because factors affecting dissatisfaction to treatments are misleading. This observational multicentric national study is aimed to assess which factors are related with a clinically significant improvement in patients with CC and IBS-C. Patients will be evaluated at baseline and after every one-month "standard of care" therapy with standardised questionnaires to assess bowel habit and satisfaction to treatments. Somatisation, quality of life, colonic transit time and resting anal pressure will be assessed at baseline.

The structural/RSN study involves Structural and Resting State Neuroimaging. The purpose of Structural Neuroimaging is to use MRI technology to identify cortical and white matter morphometric differences between patients with chronic pain conditions and healthy control subjects. The purpose of the Resting State Neuroimaging study is to use functional MRI to identify possible disease related differences in various resting state networks in the brain. In addition we are looking at the effect gut microbiota on brain function in healthy and IBS participants. The overall goal is to identify structural and functional brain differences in persons with chronic pain conditions such as Irritable Bowel Syndrome (IBS, Cyclical Vomiting Syndrome(CVS) and vestibulodynia/vulvodynia. We are also looking at Inflammatory Bowel Disease(ulcerative colitis and Crohn's disease. We will be comparing differences between these conditions and matched healthy control subjects.

After standard endomicroscopy with fluorescein to investigate for dysplasia in Barrett's esophagus the endoscope will be forwarded into the 2nd part of the duodenum. Fluorescein is needed for CLE but is not part of the investigation. Initial CLE baseline images will be taken to assure intact mucosa and allow later detailed baseline counts of intraepithelial lymphocytes (IEL) and epithelial breaks in the duodenal mucosa. Thereafter, either 10 ml NaCl 0.9% or 100µg CRF topped up to 10ml with NaCL 0.9% (according to randomisation) will be injected intravenously. Endoscopist and assistant staff will be blinded to the randomisation. Subsequently, the gut surface will be examined for at least 5 min with endomicroscopy for any change in IEL, epithelial breaks/gaps with extrusion of fluorescein into the gut lumen and widening of intervillous space. Post procedure mucosal fluid will be aspirated for assessment of mast cell tryptase and eosin catatonic protein (ECP), and 8 duodenal biopsies will be taken for 1) electron microscopy to visualise mast cell degranulation and 2) paraffin embedding for subsequent staining for mast cell tryptase to identify mast cell activation and numbers. The procedure will take around 15 minutes in addition to the routine investigation performed prior to the study. A study outline is presented in figure 1. Samples taken are the same amount as done in the previous food associated study.

The aim of the current study is to test the hypothesis that patients with IBS may have a defective ICV pressures and may have small bowel bacterial overgrowth. The goal of the current study is to identify the role and competence of ileocecal valve (ICV) in patients with irritable bowel syndrome. The primary objective is to measure the pressure of the ileocecal valve in patients with and without irritable bowel syndrome (IBS). The Ileocecal valve reflux pressures during air insufflation of cecum will be used.
