Active clinical trials for "Intestinal Diseases"

In this study it will be explored whether the levels of fecal biomarkers are associated with histologic inflammation of the intestinal mucosa and concomitant alteration of the mucosal permeability. The aim of the study is to assess the diagnostic accuracy of fecal biomarkers especially to detect the potential of differentiation between inflammatory and functional gastrointestinal diseases. The following biomarkers will be examined in the stool of the participants: calprotectin, lactoferrin, pmn-elastase, human beta-defensin, zonulin, alpha-antitrypsin.

UCon 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.

Diagnosis 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.

This 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).

this 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.

The 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.

Small 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.

An 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.

Primary 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.

Summary Purpose and Objective: The purpose of this study is to test the feasibility of rapid acquisition of point of care 3D ultrasound in obtaining abdominal and/or pelvic images. The study will use a newly developed acquisition method and post-processing technique to create three dimensional image models of the abdomen and/or pelvis. Study activities and population group. The study population will be a convenience sample of patients of any age presenting to the Emergency Department with complaints necessitating a clinical abdominal and/or pelvic imaging. The study intervention includes acquisition of research ultrasound images, which will not be used for clinical care, and comparison of these images with clinically obtained images. Other clinical data such as surgical and pathology reports will also be reviewed. 3.Data analysis and risk/safety issues. This is a pilot study intended to determine feasibility and to refine image reconstruction algorithms. Research images will be compared to clinical images. Comparison of research images with final diagnosis will also occur. The research intervention, an ultrasound exam, has no known safety risks. The only risk to subjects is loss of confidentiality. This study is observational, not interventional, because the experimental ultrasound will be performed in all subjects and will not be used in the clinical care of patients (consequently, will not have the opportunity to affect clinical outcomes). Experimental images will be reviewed after completion of clinical care and will not be provided to the clinicians caring for the subjects. The investigators are not measuring the effect of the ultrasound examination on the subjects' outcomes.
