Active clinical trials for "Colitis"

The primary objective of this study is to confirm the long-term efficacy (remission and maintenance in remission) of current validated treatments. Each patient will be followed during 3 years in this non-interventional trial.

To evaluate the safety and efficacy of the NaviAid™ AB in children with known or suspected IBD.

The risk for colon cancer in patients with longstanding ulcerative colitis exceeding the rectum is increased and therefore patients should be enrolled in a surveillance program eight years after the diagnosis. Until today, official international guidelines for endoscopic screening in patients with ulcerative colitis advise to take 4 biopsies every 10 centimeters (with a minimum of 32) and of each suspected visible lesion. These guidelines are merely based on consensus during expert opinion meetings rather than evidence based. Recent studies have shown that chromo-endoscopy guided biopsies significantly reduced the number of biopsies for each procedure and detected more neoplastic lesions. Chromo-endoscopy is therefore considered the gold standard in this study in which we want to compare it to the performance and efficiency of new endoscopic imaging techniques. Narrow-Band Imaging (NBI) selectively uses certain wavelengths of the visible light leading to a shift in the excitation spectrum towards blue light. The first studies with NBI showed that the additional value of NBI in the detection of neoplastic lesions is comparable to chromo-endoscopy, but time saving and easier to perform. The Fujinon Intelligent Chromo-Endoscopy (FICE) system uses a similar theoretical principal as NBI but this is achieved via the use of post hoc computer algorithms, applying different filters to the stored endoscopic images and enabling a theoretically endless number of combinations of filters that can be used. The Pentax I-scan system also allows post hoc modification of the images. On the one hand, surface enhancement enables to better highlight mucosal changes. Spectral modification allows to apply different modes in analogy with to FICE system. These new imaging techniques have a theoretical advantage which is extendedly used for sales purposes but has however so far not been proven in ulcerative colitis patients. We want to test their clinical use in the screening for neoplastic lesions in patients with long standing ulcerative colitis.

This prospective pilot study of 30 pediatric subjects, that are indicated for standard colonoscopy due to follow-up of ulcerative colitis (UC), examines the Given Diagnostic System and the PillCam Colon Capsule in comparison to standard colonoscopy. This study aims To evaluate and compare the accuracy of PillCam ™ Colon capsule endoscopy (PCCE) with standard colonoscopy in the evaluation of colon in pediatric ulcerative colitis. To evaluate the safety of PillCam ™ Colon capsule endoscopy (PCCE) in pediatric age.

The purpose of this study of this study is to assess the responsiveness and validity of CIMS (Central Image Management System)-based endoscopic evaluation of UC (Ulcerative Colitis) clinical disease activity by measuring: The responsiveness central reader endoscopic EIs [(Endoscopic Indices) (MMCS (Modified Mayo Clinic endoscopy Subscore), UCEIS (Ulcerative Colitis Endoscopic Index of Severity) MBS (Modified Baron Score)] to clinical change from baseline to week 6 in a prospective trial of a treatment of known efficacy in UC.

The transition from pediatric to adult IBD care can be stressful and wrought with challenges including access to care and establishment of new physician-patient relationships. There a few studies which characterize patterns of healthcare utilization during this critical period and its impact on outcomes. We hypothesize that uninterrupted healthcare utilization in academic centers and optimized communication with patients during the pediatric-adult transition period is associated with lower hospitalizations and surgery. This hypothesis will be addressed by a randomized clinical trial to determine the impact of monthly regular telephone contact with an IBD Registered Nurse versus standard of care during the pediatric-adult transition period. Outcomes will include healthcare utilization, health-related quality of life, patient satisfaction, and treatment adherence over 12 months of follow-up. Randomization and analyses will be stratified by whether subjects were transferred to adult care in an academic center or in a community practice. We hope that this research will facilitate optimal delivery of healthcare during the pediatric-adult transition.

Two thirds of patients with Crohn's disease require intestinal surgery at some time in their life. Intestinal strictures, that is narrowing of the bowel due to inflammation and scarring, are the most common reason for surgery. Despite the high frequency, associated disability, and cost there are no are no treatment strategies that aim to improve the outcome of this disease complication. The STRIDENT (stricture definition and treatment) studies aim to determine biochemical and imaging features associated with the development of strictures and in related STRIDENT studies develop strategies for treatment.

This study aims to provide new mechanistic insights into the molecular determinants of response or nonresponse to Janus Kinase inhibitor therapy and the biological heterogeneity that exists in Ulcerative Colitis. This study will include patients who are initiating Janus Kinase inhibitor therapy according to standard of care. This study consists of: Part 1: 8 or 10 week induction therapy followed by an 8-week maintenance therapy Part 2: Patients who continue Janus Kinas inhibitor therapy after part 1 will be followed further for a total of 2 years, or until discontinuation of Janus Kinase inhibitor therapy (whichever is first)

The dimension of diagnostic procedures and therapy of chronic inflammatory bowel diseases largely depends on the degree of mucosal inflammation. Video colonoscopy is currently the gold standard in the evaluation of the mucosa in patients with Ulcerative Colitis (UC). PillCam Colon Capsule was developed by Given Imaging, Israel, as possible alternative imaging modality to evaluate mucosal changes in patients with UC. The colonic mucosa can be visualized and recorded by video while the colon capsule passes the colon. Many patients suffering from UC ask their physician for possible alternative diagnostic imaging because they are uncomfortable with conventional colonoscopy. The primary aim of the present study is to compare the new Pillcam Colon Capsule with standard colonoscopy with respect to assessing mucosal disease activity and localization of inflamed colonic mucosa in patients with known UC.

Clostridium difficile is a bacteria that can infect the colon and cause severe diarrhea in patients after recent antibiotic use. The current standard of care treatment for severe C. diff. consists of oral vancomycin and/or intravenous metronidazole. When treatment is unsuccessful, it can lead to need for removal of the entire colon or even death. In fact, mortality rates in the literature range from 11-37% for C. diff. The most commonly quoted mortality rate is 14% for severe infection. It is believed that the failure of treatment may stem from an adynamic ileus (paralysis of the small bowel). This ileus may prevent the oral vancomycin from reaching the colon and therefore it does not treat the problem. Vancomycin functions by direct contact with the colon. It is presumed that this paralysis of the small intestine is present but has never been proven. The objective of the study is to prove that there is an adynamic ileus present in c. diff colitis and therefore lead to investigations into improved treatment.
