Active clinical trials for "Colitis, Ulcerative"

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

The cause of Inflammatory Bowl Disease (IBD) is not known, but studies from patients with IBD have found that these patients make unusually strong immune responses to their own intestinal tissues and to bacteria that normally live in the healthy gut. These overactive immune responses might result from an imbalance of T-lymphocytes, which are a type of white blood cell that recognize and respond to threats like infection or damaged tissues. In healthy tissues, a type of T-lymphocytes called T-regulatory cells control excess inflammation by preventing other T cells, called T-effector cells from responding. We believe that T-regulatory cells are somehow less active in IBD, resulting in damage to intestinal tissues by the T-effector cells. T-lymphocytes, including both T-regulatory and T-effector cells, are guided to different parts of the body by 'alpha4beta7-integrin' molecules. Vedolizumab or Entyvio works by blocking this homing molecule so that T cells do not reach the intestine, but stay in the blood where they cannot aggravate your IBD. This study will help in understanding how Vedolizumab helps to heal or decrease the symptoms of your Ulcerative Colitis. The effect of Vedolizumab on different types of T cells in the human intestine has not yet been studied. However, the investigators think that Vedolizumab will shift the balance of T cells in the intestine towards more healing T-regulatory cells and less damaging T-effector cells. The purpose of this study is to measure the different types of T cells in participants' blood and intestinal tissue before and during Vedolizumab treatment.

The purpose of this study is to develop an artificial intelligence(AI) assisted scoring system, which can evaluate the disease severity and mucosal healing stage in patients with ulcerative colitis. Then testify whether this new scoring system can help physicians to enhance the accuracy of disease severity assessments in a multi-center clinical practice.

A prospective study to investigate the dynamic changes of gut microbiota through colonic transendoscopic enteral tubing in patients with ulcerative colitis after fecal microbiota transplantation.

Introduction Acute severe ulcerative colitis (ASUC) occurs in 15-25 % of all ulcerative colitis (UC) patients. Initial treatment with intravenous corticosteroids fails in 30-50 % of patients, for whom the next line of treatment is biological therapy or colectomy. Acute colectomy has a higher risk of morbidity and mortality than a scheduled colectomy. Data suggest that an accelerated administration of biological treatment in corticosteroid non-responders compared to clinical practice, 5-7 days with intravenous corticosteroids, may be superior in inducing disease remission, thus potentially avoiding acute colectomy. However, there are currently no patient friendly and objective diagnostic tool to preselect patients for such a treatment. The aim of this study is to examine if gastrointestinal ultrasound (GIUS) could preselect corticosteroid non-responders to biological treatment after 48 hours to increase effectiveness of the second line therapy and thereby reduce the morbidity and mortality of ASUC. Methods and analysis The study is a clinician blinded observational multi-center study derived from the Department of Gastroenterology, Herlev Hospital, Denmark. Fifty ASUC patients will be included at the time of hospitalization and followed for 12 months. Baseline clinical activity scores, endoscopic scores, blood samples, fecal-calprotectin, vital parameters and GIUS measurements will be obtained prior to administration of intravenous corticosteroids. All examinations except fecal-calprotectin and endoscopy will be repeated at 48 ± 24 hours, 5-7 days and 3 months after treatment start. Endoscopic scores and fecal-calprotectin will be obtained after 3 months and an additional fecal-calprotectin after 6 ± 1 days. Treatment outcome will be registered at each event and after 12 months. Patients will be divided into corticosteroid responders and non-responders and compared to GIUS measurements at each event using non-parametric statistics (Mann-Whitney and Wilcoxon test) and time to endpoints by survival statistics (Kaplan Meier). ROC statistics will determine the best cutoff values for GIUS parameters for optimal sensitivity, specificity and accuracy. Ethics and dissemination The study is approved by the National committee on health research ethics (H-18031264). Results will be published in relevant scientific journals and presented at international conferences. Fully anonymized data will be accessible from authors upon request.

Patients with inflammatory bowel disease (IBD) are increasingly becoming interested in nonpharmacologic approaches to their disease. One of the most frequently asked questions of IBD patients is what they should eat. The role of diet has become very important in the prevention and treatment of IBD. Although there is a general lack of rigorous scientific evidence that demonstrates which diet is best for certain patients, several diets have become popular. Aim of the Work To assess IBD patients' knowledge about the role of nutrition in the management of their Inflammatory Bowel Disease and the dietary beliefs, behaviors, and daily dietary practices in adult IBD patients that they make to avoid exacerbation of disease symptoms or to gain more control of bowel symptoms, keeping in mind our traditional and oriental food and food habits in Egypt. Also to evaluate the role of one of the most common dietary regimens; the Paleolithic diet in active mild or moderate inflammatory bowel disease.

This study tests the hypothesis that a supplement that combines a functional fiber, long chain omega-3 polyunsaturated fatty acids (PUFAs), vitamin D3, vitamin E, and zinc will reduce clinical symptoms, decrease pro-inflammatory cytokines in the blood and ergo decrease inflammation, promote beneficial microbial activity in the colon, and help recovery of the intestinal mucosa of ulcerative colitis (UC) patients compared with a placebo.

Investigators aimed at investigating the prediction ability of faecal calprotectin to predict mucosal healing and histological remission in ulcerative colitis patients receiving biological therapy Investigators aimed to evaluate the prediction ability of NLR, PLR and MLR to predict mucosal healing and histological remission in ulcerative colitis patients receiving biological therapy. Investigators evaluate the histological remission in ulcerative colitis patients receiving biological therapy in Assuit university hospital.

The purpose of this study is to gain insights in the pharmacokinetics of golimumab in moderate to severe Ulcerative Colitis after subcutaneous administration, during induction and maintenance treatment the investigators will collect blood and stool samples at different time points.

This study aims to characterize the Portuguese population of patients with moderate-to-severe UC receiving advanced therapies, by describing clinical and sociodemographic characteristics, and remission outcomes . The clinical, biochemical, endoscopic, and histological outcomes will also be described, as well as frequency of selected EIM, comorbidities and the uptake of preventive care measures and hospitalizations .
