Active clinical trials for "Colitis"

The purpose of this registry is to collect information about patients in which a pouch has been created to improve in the future the quality of the surgery of the pouch.

The purpose of this study is to conduct a translational study in patients with primary eosinophil associated gastrointestinal disorders [EGID] (e.g. eosinophilic esophagitis eosinophilic gastritis, eosinophilic enteritis [EE], eosinophilic colitis, and eosinophilic gastroenteritis [EGE]) with the aim of developing a data bank containing pertinent patient demographic information, tissue samples, and DNA, which will facilitate research on the pathophysiology of inflammatory disorders and the development of a verified successful clinical treatment program.

Long-standing ulcerative colitis is associated with an increased cancer risk. Chromoendoscopy with dye spraying can detect subtle abnormalities that are not visible with standard endoscopy. The purpose of this study is to determine if chromoendoscopy with fewer "targeted biopsies" can replace standard colonoscopy with multiple "random" biopsies.

The PREdiCCt Study: This is a major study that is now being launched. This is the first study of its kind and is specifically directed toward understanding how environmental factors and the gut microorganisms influence IBD flare and recovery. For the PREdiCCt study, the investigators hope to recruit 3100 people in remission from Crohn's disease or ulcerative colitis (illness under control) from 28 inflammatory bowel disease clinics across the UK. The investigators hope to conduct the study in the following stages;- Patients with Crohn's disease, ulcerative colitis or inflammatory bowel disease unclassified (IBDU) in clinical remission (under control) will be approached in gastroenterology clinics across the country and invited to take part in the PREdiCCt study. Alternatively they will express their interest in the study after seeing PREdiCCt promotional leaflets/posters/videos/social media. Participants will attend a clinic visit for routine tests and also to complete several questionnaires with a research nurse. At home over the next week participants will complete detailed questionnaires assessing their environment and diet. Participants will also collect a stool and saliva sample and send this to our laboratories (the investigators have developed easy ways of doing this reliably by post). The stool sample is to analyse the microorganisms in the participant's gut and the saliva is used to analyse their DNA. In addition to this the participants are asked to complete a 4-day weighed food diary. The food diary is sent to the University of Aberdeen for analysis. Investigators will then follow patients' progress over 24 months. They will be asked to complete a short questionnaire every month with a longer questionnaire after 12 months and culminating in a final questionnaire 24 months after their initial clinic visit. If a participant experiences a flare, investigators will collect an additional stool sample; but most importantly investigators will look to see how the environmental and microorganism factors recorded at the beginning differ for those that flare up versus those that don't. What investigators hope to achieve;- Finding out the environmental and dietary factors for patients to avoid because they trigger flare. Finding out behaviours for patients to adopt because they bring about remission. Finding out what the microorganisms that predict flare look like. Gaining information which helps future studies aimed at finding better diets for IBD sufferers. Developing ways of gathering information online from IBD patients about their well-being that doctors can routinely use. The investigators have assembled expert doctors, epidemiologists, microbiologists, nutrition scientists, and bioinformaticians. These experts will use the systems the investigators have put in place to make sure PREdiCCt succeeds. It will yield a lot of new information to help sufferers right away; but the information will also help to kick start many important future studies that will bring us ever closer to a cure for Crohn's disease and ulcerative colitis.

TNF inhibitors have improved treatment options for patients with inflammatory bowel disease (IBD) and three TNF inhibitors, infliximab, adalimumab and golimumab are available for treatment of ulcerative colitis in Switzerland. However, these drugs have been tested under ideal conditions in randomized controlled trials. Real-world data are needed to complement this information. It is the aim of our study to test, whether patients with ulcerative colitis can be effectively treated with golimumab in a real world setting in Switzerland. The investigators will use data from the Swiss IBD cohort study (SIBDC) in Switzerland. They will identify all SIBDC patients with UC treated with Golimumab and perform a retrospective chart review. The investigators will acquire patient reported outcomes and objective measures for inflammation at baseline, at 6-10 weeks and at 6 and 12 months after golimumab treatment. Primary endpoint will be clinical response (i.e. meaningful improvement) at 6-10 weeks. Secondary endpoints will be clinical response at 6 and 12 months and clinical remission (i.e. free of symptoms of disease).

The surgical treatment of the ulcerative colitis (UC) remains associate to a significant morbidity (up to 60%). Anastomotic fistula and pelvic sepsis are the most severe complications which could dramatically compromise the surgical issue and functional status. Thanks to the current therapeutic arsenal and the evolution of health care paradigms, the quality of life of patients plays a key role in the modern global management of these medical conditions. Biotherapies (e.g anti-TNF) are widely used to treat patients with UC. Anti-TNF and anti-integrins have an effect on the immune response and can theoretically aggravate the infectious disease. Their potential impact on postoperative complications after ileo anal anastomosis (AIA) remains debated. Very few studies have looked at other biotherapies including vedolizumab. All studies are retrospective series with small sample size. Here again the conclusion remain contradictory. Lightner et al. showed an increased risk of surgical site infection for patients preoperatively exposed to vedolizumab (37% vs. 10%, p <0.001). In a dedicated cohort to the RCH, the same author found a risk of increased pelvic abscess (31.3% vs 5.9%, NS) but the difference was not statistically significant probably for lack of power. Other studies did not find any impact of vedolizumab on the risk of postoperative complications. To clearly determine within a large prospective cohort the impact of anti-TNF agents and biotherapies on the postoperative complications seems to be essential in order to adapt and to optimize the therapeutic strategy, especially the surgical sequences, in patients with UCR whom benefit a surgery.

Ulcerative colitis (UC) is a chronic inflammatory condition causing continuous mucosal inflammation of the colon, which is accompanied by episodes of bloody diarrhoea and abdominal pain. Both infliximab and adalimumab have been used with success for moderate-to-severe UC refractory to conventional therapy. More recently, golimumab, another anti-TNF antibody, has been added to the treatment armamentarium. In the multi-centre, double-blind, placebo-controlled PURSUIT trial, patients with moderate-to-severe UC randomized to induction therapy with golimumab (200-100 mg, or 100-50 mg at week 0 and 2) achieved clinical response, clinical remission and mucosal healing more frequent than patients randomized to placebo. In the PURSUIT maintenance trial, patients randomized to golimumab every four weeks (100 or 50 mg) maintained clinical response through week 54 significantly more often than patients randomized to placebo. Data on the use of golimumab in daily clinical practice are unavailable. The aim of the retrospective Belgian multi-centre BE-SMART trial is to evaluate the mid-term outcome of golimumab in patients with moderate-to-severe colitis. The primary endpoint will be steroid-free golimumab continuation at week 26. Secondary endpoints will include (steroid-free) clinical remission, (steroid-free) clinical response, (steroid-free) mucosal healing, (steroid-free) complete mucosal healing hospitalization-free survival, and colectomy-free survival.

Ulcerative Colitis (UC) is a disease known for repeated relapses and remissions. So, meticulous follow-up is required to individualize treatment plans according to the status of each patient. The currently used investigations are invasive, costy, and carry the risk of several side effects, making it difficult for the patient to adhere to his continuous follow-up. Aim: To evaluate the viability of fecal lactoferrin, serum ferritin, and IL6 as noninvasive markers for detecting the activity and follow-up the patients of ulcerative colitis during remission.

The aim of this study is to evaluate the evolution and possible factors associated with the persistence of fatigue in patients with quiescent IBD and fatigue included in two previous studies.

The aim of the study is to construct and validate an endomicroscopic score correlated with microscopic inflammation activity in patients with UC. Probe-based confocal laser endomicroscopy (pCLE) is a new endoscopic imaging modality, which offers the possibility to perform in vivo mucosal microscopic analysis in real time during endoscopy. Primary Objectives : Development and validation of a UC endomicroscopic score, after correlation between pCLE data and histological data using the Geboes' score as a gold standard during ulcerative colitis. Secondary Objectives: Identify predictive factors for the response to adalimumab. Identify predictive factors for recurrence in patients with UC in remission (Mayo score 0 or 1). Safety of the pCLE procedure
