Active clinical trials for "Colitis, Ulcerative"

The aim of the study is to do a 7-year follow-up of a consecutive inception cohort of 562 adults and children diagnosed and registered with inflammatory bowel disease in 2003-04 in order to evaluate the consequences of biological therapy in the treatment of IBD. The cohort is established after the implementation of biological agents in the treatment of IBD and the investigators hypothesis is that a) Severe disease course in IBD can be predicted by phenotypic presentation by serological, genetic, clinical and endoscopic characteristics to be used as guidance in the selection of treatment strategy and b) Introduction of biological treatment changes the course of disease in IBD and reduces the need of surgical procedures. Methods: Medical records will be reviewed to register the use of medication, flare ups (medical and surgical) and hospital admissions. Diagnosis, disease localization and behavior will be evaluated. At outpatient visits patients will get a clinical examination, blood and faeces will be collected to biobank and patients will be offered an endoscopical examination. The Montreal classification, The Harvey & Bradshaw's activity index (CD) and the SCAAI score (UC) will be used to describe disease localization, extent, behavior and severity. An electronic database will be established in use of processing data.

Patients with longstanding ulcerative colitis or crohn's disease in the large bowel have an increased risk of developing cancer. The purpose of this study is to determine if visualizing of the mucosa in details using a dye spray (indigo-carmine) will result in detection of more abnormalities than conventional colonoscopy without dye spray.

The proposed study is a post marketing, observational, retrospective data collection intended to gather and record data on patients treated with the ColonRing™ device in routine clinical practice at a single center. The data will assist in further evaluating the performance of the ColonRing™ device in regards to the creation of a colorectal anastomosis. Hypothesis:The performance of the ColonRing™, determined by the rate of complications, will be within the acceptable range reported in the literature for alternative treatment modalities.

The purpose of this study is to produce a user-friendly tool- in the form of a questionnaire - to accurately assess early quality of life in patients after abdominal colorectal surgery from the first day after surgery to 6 months after. The study will also compare this questionnaire to the other currently available assessment tools. Patients are invited to participate if they are undergoing abdominal colorectal surgery at University Hospitals of Cleveland.

The prevalence of ulcerative colitis (UC), which is one of the inflammatory bowel diseases, is known to be increasing and the majority of patients (≥ 85%) have experienced mild or moderate severity. 5-Aminosalicylic acid (5-ASA), immunomodulator, or biologics, etc are prescribed to treat UC, however 5-ASA is generally considered the first-line therapy. The recent UC treatment guideline in Korea and the United States/ European Union (US/EU) have recommended higher daily dose for patients with mild or moderate severity than the previous guidelines since 2017. Accordingly, it is assumed that the average daily treatment dose of 5-ASA would increase in patients who were initially diagnosed with UC in real-world clinical practice in Korea. However, there are not many studies evaluating the treatment patterns and health outcomes of 5-ASA based on the recent treatment guideline in South Korea. This study, hence, aims to investigate the impact of changes in daily dose of 5-ASA on the treatment patterns and health outcomes such as recurrence rate, hospitalization rate, and surgery rate in real world practice using Health Insurance Review and Assessment (HIRA) claims database.

The hypothesis of the study is that in ulcerative colitis repeated flares of inflammatory activity, as well as mechanisms involved in resolution of the inflammatory response, may contribute to accumulation of damage in the colon leading to functional disturbances and symptoms that affect patient's functioning. The primary objective is to determine whether ulcerative colitis induces permanent anatomical damage, by means of magnetic resonance imaging.

The purpose of this study is to describe the initial response to ustekinumab induction treatment for ulcerative colitis (UC) in Japan.

Background and rationale: In ulcerative colitis, treating beyond endoscopic healing has shown a reduction of relapse and hospitalization, pushing for histological remission in daily clinical practice.1 However, very little is known on how histological remission is associated with patient reported outcomes (PROMs).2,3 In recent years, several questionnaires have been developed to assess what really matters to patients: symptoms and the burden UC exerts on them.4 As PROMs are getting more and more attention during drug development programs and drug approval by international organizations, including FDA and EMA, the link between objective outcome measures (endoscopic, histological, biochemical) and PROMs should therefore be better characterized. Objectives and design: To investigate prospectively the association of patient reported outcomes (PROMs) and biochemical, endoscopic and histological outcome measures in patients with ulcerative colitis.

The purpose of the study is to develop a validated French version of the IBDQ in a cohort of patients suffering from Inflammatory bowel diseases, namely Crohn's disease and Ulcerative Colitis.

The purpose of this study is to evaluate the relation between sulphide detoxification and butyrate metabolism at the level of gene expression and enzyme activity in ulcerative colitis patients and healthy controls.
