Mechanism of Chronic Pain in Patients With IBD
Inflammatory Bowel DiseasesAbdominal pain is a common symptom in patients with inflammatory bowel disease (IBD). Up to 70 % of IBD patients experience pain when the disease is active. Even when patients with IBD are in remission, 20-50 % experience ongoing pain. The precise mechanism of developing chronic abdominal pain in patients with IBD in remission remains unknown. The aim of this study is to identify psychophysiological and biological risk factors for the development of chronic abdominal pain in patients with newly diagnosed IBD (ulcerative colitis and Crohn's disease). This study consists of 4 sections (Study 1A, 1B, 2, and 3): Study 1A: We perform a longitudinal study in 150 patients with new-onset IBD over 18 months to identify risk factors related to the brain-gut axis for the development of chronic pain. This is a collaborative study with IBD BioResourse Inception study. We administer online questionnaires, collect stool and blood samples, and record heart rate. Other physiological data collected by the Inception study will be also used for the analysis. Study 1B: This is also a collaborative study with the Inception study. We will apply for our detailed questionnaires for 7 days (as per study 1A) to be administered to all the new patients (n=450) that are included in the Inception study on a voluntary basis. Patients will be followed for 12 months. Study 2 and 3: Study 2 and 3 are a questionnaire-based cross-sectional study in patients with IBD. The participants for study 2 are patients registered in IBD BOOST study and those for study 3 are patients registered in IBD BioResource (but not in IBD Boost study). Detailed online questionnaires will be administered to them. These studies are just one-day assessment.
Safety and Performance of UCon Bar Electrode for the Treatment of Overactive Bladder (OAB) and Bowel...
Urinary IncontinenceUrinary Incontinence8 moreUCon is a medical device for treatment of the symptoms of overactive bladder (OAB) and bowel dysfunction (BD). It electrically stimulates the DGN through the skin to obtain modulated behaviour of the bladder/bowel musculature e.g., suppress undesired bladder/bowel activity to relieve the symptoms of the patient. This clinical investigation is designed as a single-arm, prospective, multi-centre, and early feasibility study.
OptiMized REsistaNt Starch in Inflammatory Bowel Disease: The MEND Trial
Crohn DiseaseUlcerative Colitis1 moreThe purpose of the study is to determine if a plant-based resistant starch that is optimized for the individual will target the underlying cause of inflammatory bowel disease and restore a "healthier" gut microbiome in pediatric participants with inflammatory bowel disease.
Exploratory Investigation on a Novel Catheter
Bowel DysfunctionAn exploratory, pre-market, open, prospective, interventional, clinical investigation at a limited number of centers for proof of concept of a new catheter. In this proof of concept investigation, subjects experienced in using transanal irrigation (TAI) with a balloon catheter will be using study catheters at two occasions to primarily study if the catheter will stay in place during the water instillation when performing TAI. Each subject will be followed during approximately one week, depending on the usual time between their TAI.
Small Bowel Evaluation Using Novel Motorized Spiral Enteroscopy
Small Bowel DiseaseSmall bowel evaluation using Novel Motorized Spiral Enteroscopy - Prospective non-controlled clinical study from a single tertiary care centre. Data regarding the safety and efficacy of Novel Motorized Spiral Enteroscopy in the evaluation of the small bowel, most of them are retrospective. This study is being planned to collect the data prospectively for all the patients undergoing this procedure at our center including the follow up at 1 month for any adverse events.This will enlighten us in understanding the role of Novel Motorized Spiral in the evaluation of the small bowel Enteroscopy in the small bowel evaluation.
A Systems Biology Approach for Identification of Host and Microbial Mechanisms and Druggable Targets...
Inflammatory Bowel DiseasesPrimary Sclerosing CholangitisPrimary sclerosing cholangitis (PSC) is the classical hepatobiliary manifestation of inflammatory bowel disease (IBD). Although rare, PSC is associated with significant and disproportionate unmet needs; with heightened risks of colorectal cancer and colectomy, and greater all-cause mortality rates compared to matched IBD patients. Unfortunately, no medical therapy has been proven to slow disease progression in PSC-IBD, and liver transplantation is the only lifesaving intervention for patients. The strong association between PSC and IBD has led to several pathogenic hypotheses, in which dysregulated mucosal immune responses are proposed to contribute. Of note, the investigators recently identified distinct mucosal transcriptomic profiles in PSC-IBD; with regards bile acid metabolism, bile acid signalling, and a central role of enteric dysbiosis. In parallel, pilot data from other groups have shown that treatment with oral vancomycin (a non-absorbable, gut-specific antibiotic) attenuates colonic inflammation and improves biochemical markers of cholestasis in PSC. However, there is no mechanistic data exploring the host-microbial alterations under vancomycin treatment in PSC-IBD, neither the impact of vancomycin on bile acid circulation. The investigators of this study hypothesize that oral vancomycin attenuates colonic mucosal inflammation in PSC-IBD, by restoring gut microbiota mediated bile acid homeostatic pathways. Through these means the study aims to identify druggable gut microbial and host molecular pathways associated with bile acid mediated colonic mucosal inflammation in PSC-IBD.
Preclinical Evaluation of Multimodal Therapeutic Strategies in Intestinal Irradiation and Inflammatory...
Radiation EnteritisInflammatory Bowel DiseasesThis study is carried out in patients with IBD and healthy subjects requiring ileocolonoscopy as part of routine care (disease monitoring or polyp/colon cancer screening). It aims the generation and culturing of organoids from digestive biopsies recovered from healthy and/or pathological (inflammatory) ileal and/or colonic mucosa during an ileo-colonoscopy. These cultures will make it possible to validate the organoid production method used in the context of the research (primary objective). In a second phase (secondary objectives), the study will aim to setup a screening tool by irradiating the organoids (step one) and then evaluate in vitro the regenerative activity of treatments dedicated to improve inflammatory bowel diseases and acute radiation enteritis (step two).
The Efficacy of Exercise Therapy in Patients With Inflammatory Bowel Disease
Inflammatory Bowel DiseasesSarcopeniathis study aims to determine the effect of 8 weeks of exercise on the quality of life and muscle strength of patients with IBD. Patients will be randomized into 1) Intervention group: doing aerobic and resistance exercise according to physiotherapist prescription and 2) Control group: usual medical care. Both groups will continue their medications prescribed by the Gastroenterologist. After 8 weeks patients come back to the hospital for reevaluation of measured indices. The primary outcome of this study is the patient quality of life assessed by the IBDQ questionnaire. Other outcomes that will be evaluated before and after 8 weeks are muscle strength measured by a dynamometer and laboratory markers such as ESR and CRP and tool calprotectin. Also, disease activity using partial mayo score and Harvey Bradshaw score will be calculated and compared before and after treatment.
Utility of Motorized Spiral Enteroscopy for Suspected Small Bowel Pathology
Small Bowel DiseaseDiagnosis and treatment of small bowel pathologies remain challenging due to the long length of the small bowel. Obscure gastrointestinal (GI) bleeding with negative upper and lower GI workup, suspected inflammatory bowel disease, and suspected tumors of the small bowel often require small bowel investigation. While video capsule endoscopy (VCE) and computed tomography (CT) enteroclysis (CTE) are often the initial diagnostic modalities for suspected small bowel pathologies and can provide structural information of the small bowel mucosa, biopsy or therapy for the detected pathology could not be performed with VCE or CTE. In patients who require biopsy or therapy of the detected small bowel pathology, deep enteroscopy would be the procedure of choice in modern clinical practice before subjecting patient to surgery. Diagnostic and therapeutic deep enteroscopy can be performed by balloon overtube assisted enteroscopy (eg, double balloon enteroscopy (DBE), single balloon enteroscopy (SBE) or spiral overtube assisted enteroscopy (SE). Despite the difference in equipment design of DBE, SBE, and SE, the concepts for small bowel intubation by pleating the intestine over the endoscope are the same behind these techniques. Depending on the location of the small bowel pathology reported by VCE or CTE, antegrade (oral route), retrograde (anal route), or combined antegrade and retrograde deep enteroscopy for total enteroscopy can be performed.
The Canadian Children Inflammatory Bowel Disease Network (CIDsCaNN)
Inflammatory Bowel DiseasesCrohn's1 moreThe initial network clinical study will be an inception cohort study in children with IBD (Inflammatory Bowel Disease) rigorously phenotyped and prospectively followed. Focusing on a prospective, inception cohort of Canadian children of widely varied racial origins provides a unique opportunity to explore environmental risk factors early in life and close in time to disease onset, their influence on the host microbiome, and in the context of genetic susceptibility. In keeping with current treatment targets, assessed outcomes will include not only symptom resolution and growth, but also intestinal healing. Anticipated variation between network sites in choices of evidence-based therapies, even among phenotypically similar sub-types of Crohn disease and ulcerative colitis, will allow comparisons outcomes with disparate treatments, aiming to identify best practice and to institute processes for continual improvement in care nationally.
