Filter by: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.
This study assesses the long-term safety and efficacy of adalimumab in pediatric subjects with ulcerative colitis.
The main aim of the study is to check for long-term side effects of Vedolizumab Subcutaneous (also known as Vedolizumab SC) in people with ulcerative colitis and Crohn's disease. Vedolizumab SC will be given as an injection just under the skin. This type of injection is called a subcutaneous injection or SC for short. Another aim of the study is to collect information on whether the participant's condition remains under control or improves during and after treatment with Vedolizumab SC. Participants who previously took part in studies MLN0002SC-3027 or MLN0002SC-3031 will be invited to visit the study clinic. At this visit, the study doctor will check if each participant can take part in this study. For those who can take part, participants will receive a subcutaneous injection of vedolizumab SC either once a week or once every 2 weeks. How often each participant receives vedolizumab SC will depend on their results from the previous study and on how active their condition is. Participants might be able to self-inject vedolizumab SC after being trained by the study doctors. During this study, the dose of vedolizumab SC might be increased for participants whose condition worsens. Participants will continue treatment with vedolizumab SC until it is approved in their particular country, the participant decides to stop treatment, or the sponsor stops the study. If the sponsor stops the study before vedolizumab SC is approved in all countries, the sponsor will make sure all affected participants will have access to vedolizumab SC outside of the study. After their final dose of vedolizumab SC, participants will visit the clinic 18 weeks later for a final check-up. Then, the clinic will telephone the participants 6 months after their final dose of vedolizumab SC to check if they have any health problems.
The purpose of this study is to evaluate the long-term safety and efficacy of RPC1063 in participants with moderately to severely active ulcerative colitis. Only those participants who have previously participated in a trial of RPC1063, being either RPC01-3101 or completed at least 1 year of the open-label period of RPC01-202 will be eligible.
This study aims to test, if a two-week integrative therapy in an internal medicine ward will improve symptoms, disability and quality of life in patients with inflammatory bowel disease or irritable bowel syndrome.a It shall further be tested, if those changes are associated with attitudes and experiences towards complementary and alternative medicine, anxiety, depression and stress perception as well as body awareness and responsiveness.
The purpose of this study is to evaluate the effectiveness of Fecal Microbiota Transplant (FMT) for treating patients with mild to moderate Ulcerative Colitis (UC). Even with the expanding choices of medication for UC, physicians and patients are still in search of highly effective and safe medications with minimal side effects. FMT has been approved for the treatment of a bacterial infection called Clostridium difficile. In this setting, FMT has been proven to be an effective and safe alternative therapy with zero reported serious adverse events from patients that have had this treatment. The providers that are conducting this study hypothesize that delivering microbes from a healthy human gut can help treat the damages caused by UC. This is done by "transplanting" fecal material, which contains a highly complex and dense community of healthy microbes, including bacteria, fungi and viruses. This collection of microbes is referred to as a microbiome. Preliminary studies suggest that alteration of the microbiome can help treat UC.
This study aims to investigate the role of non-genetic factors in the pathogenesis of inflammatory bowel disease.An exploratory study to investigate differences between the epigenome, microbiota and functional immunology in twins discordant for inflammatory bowel disease.
The investigators will test the hypothesis that that greater efficacy of anti-tumor necrosis factor (antiTNF) therapy results in reduced need for bowel resection surgery, fewer serious infections, and reduced short term mortality risks, and therefore has a more favorable benefit to harm profile than corticosteroids for inflammatory bowel disease.
Ninety Six patients with mild to moderate ulcerative colitis will be randomized to double blind, placebo controlled study. The safety and efficacy of the intervention will be closely monitored.
The detrimental effects of catabolism, insuline resistance and muscle wasting on surgical outcome is wellknown. This catabolism is especially pronounced in patients with acute or chronic inflammation (IBD, cancer) and for those undergoing major surgery. Patients with ulcerative colitis operated with an ileal pouch-anal anastomosis (j-pouch) fall well into both these categories. To prevent this undesirable catabolism, we will investigate the effects of intravenous administration of predominantly anabolic amino acids (with an amino acid content equal to breast milk) on whole body metabolism, with special emphasis on muscle and fat metabolism and intracellular signalling pathways. Twenty-four patients will be block-randomized by gender in this parallel-group, randomized, assessor-blinded, placebo-controlled trial to receive either Vaminolac® (Fresenius Kabi) or saline. Metabolism before and after the intervention will be assessed by palmitate- and amino acid kinetics of radioactively labelled tracers, while muscle and fat biopsies will be analyzed for differences in intracellular signaling pathways (PI3 kinase, Akt, etc.) as a measure of cellular activity. With this study we hope to find evidence for anabolic effects of intravenous amino acids in j-pouch surgery for ulcerative colitis. The perspective is a potential for primary prophylaxis of surgical complications, reduction in the length of hospitalization, and subsequently optimized long-term functional outcome of the pouch.
