Active clinical trials for "Inflammatory Bowel Diseases"

Ulcerative colitis (UC) is a chronic inflammatory bowel disease that is marked by increased intestinal motility and bloody diarrhea. The clinical value of existing therapeutic strategies of UC, including glucocorticoids, anti-tumor necrosis factor α (TNF-α), mesalamine, and thiopurines is still limited. Therefore, the discovery of new therapeutic approaches is essential to improve the effectiveness of the treatment.Adenosine monophosphate (AMP)-activated protein kinase (AMPK) is a conserved fuel-sensing enzyme that plays an important role in the regulation of cellular metabolism where it increases glucose and fatty acids uptake and activates the oxidation process to improve the cellular energy utilization

The investigators propose the use of a 20 week physician-derived exercise programme will lead to an improvement in physical fitness which will in turn lead to an increase in muscle mass, a reduction in visceral obesity resulting in an improvement in biologic response, disease biomarkers (including a reduction in circulating pro-inflammatory cytokines), fatigue scores and quality of life.

The study will examine the efficacy of an internet-based cognitive behavioural therapy (iCBT) for Inflammatory Bowel Disease (IBD) intervention to reduce stress, anxiety, and depression in individuals with IBD and comorbid clinically elevated t anxiety and/or depressive symptoms. The investigators will conduct a two-arm RCT comparing participants receiving the iCBT intervention (intervention group) and those receiving Treatment As Usual (TAU).

In this research project, the investigators want to find out whether the additional intake of vitamin D further reduces the inflammatory events in the intestines of IBD patients. There are three groups of subjects: the 1st group takes a capsule of 24,000 IU per week, the 2nd group takes 24,000 IU per month, the 3rd group is the control group. The intake extends over 6 months during the autumn and winter period.

This study is a single-centre, interventional implementation and feasibility study. Patients in the IBD service will be able to access COMPASS, an online cognitive-behavioural therapy (CBT) programme, as part of standard care at Guy's and St Thomas's NHS Foundation Trust. COMPASS is an online program. It will consist of 11 online modules which target challenges associated with living with IBD (and other long-term conditions) and includes, amongst other things, psycho-education, patient examples, interactive tasks and goal setting. Participants are linked to a therapist; 'guide', who will provide 5-6 x 30 minute support sessions delivered fortnightly in the format preferred by the client (phone and/or in-site message).

The gut microbiota is considered to constitute a "microbial organ" which has pivotal roles in the intestinal diseases and body's metabolism. Evidence from animal and human studies strongly supports the link between intestinal bacteria and inflammatory bowel diseases (IBD). Dozens of studies reported its efficacy in treatment of severe Clostridium difficile colitis. Preliminary studies using FMT for Ulcerative Colitis (UC), Crohn's diseases (CD), irritable bowel syndrome (IBS) and constipation have also met with some success. However, the results on CD is very limited. This is an initial step into investigating the potential efficacy of fecal bacteriotherapy for CD, the investigators propose to determine the efficiency, durability and safety of FMT in a series of 500 patients with CD in ten years.

Crohn's disease (CD) is a chronic disease with a heterogeneous clinical presentation, relapse rate and treatment response. Insufficient control of mucosal inflammation results in irreversible bowel damage and complications and at present no markers are available to predict such a complicated disease course at diagnosis. Therefore, to prevent overtreatment of low risk patients, step-up treatment with subsequent introduction of corticosteroids, thiopurines maintenance and TNF-blockers if a previous category fails is standard care. Combination treatment with thiopurines and a TNF-blocker is more effective than monotherapy but associated with a higher risk for infectious complications. Landmark studies convincingly showed an improved long-term outcome if the TNF-blocker infliximab is introduced early after diagnosis. The standard step-care approach thus prolongs steroid exposure and delays start of disease modifying biologicals in high risks patients. Given the higher efficacy of combination therapy with a thiopurine of infliximab and potential allergic reactions and lower response rates after re-initiation of this chimeric biological, temporary monotherapy with this TNF-blocker has not been studied as first line treatment before. Adalimumab is a humanised monoclonal antibody and subsequently, combination therapy of adalimumab + thiopurines has only a marginal effect on anti-drug anti-body formation. Furthermore, combination therapy with adalimumab does not enhance the clinical response. Therefore, periodic treatment with adalimumab in combination with close monitoring after drug-discontinuation, in newly diagnosed CD might improve outcome, reduce drug-related side effects while still preventing overtreatment. The aim of this study is to compare the long-term efficacy and safety of periodic adalimumab as initial treatment in newly diagnosed CD patients compared to standard step-care with corticosteroid/budesonide as the initial treatment

This study evaluates the safety of the probiotic compound IDOFORM TRAVEL® in patients with ulcerative colitis undergoing anti-TNF treatment with insufficient clinical response. Furthermore, the study aims to explore the composition of the bacteria of the gut as well as the immunological activity in patients with ulcerative colitis undergoing anti-TNF treatment, aiming to identify differences between groups of patients responding and not responding adequately to treatment. The project will explore whether probiotics have beneficial effects as adjuvant therapy in ulcerative colitis patients with insufficient response to anti-TNF treatment.

Apart from its use to provide insight in IBS disease courses and in clinical research, ESM can provide patients with feedback about individual triggers of their symptoms, and thereby function as part of a personalized therapeutic strategy. This is also true for IBD-IBS. Treatment strategies in IBS and IBD-IBS are largely based on reassurance, identification and elimination of triggering factors, and in more severe cases pharmaco- and psychotherapy. The ESM approach has the potential to increase therapeutic efficacy in IBS and IBD-IBS and will assist patients in disease self-management. The Traqq application can provide more detailed information about the dietary pattern of IBS and IBD-IBS patients. Traqq in combination with ESM will give an overview of abdominal pain and associated symptoms and psychosocial factors are exposed to during the day. The insight provided using ESM and Traqq may improve patient understanding of their personal symptom dynamics and triggers, as well as the physician's insight into the symptom patters of the specific patients, which may aid treatment choice and eventually improve the outcome of any treatment provided in daily clinical care.

The main purpose of this study is to evaluate the long-term efficacy of mirikizumab in pediatric participants with ulcerative colitis (UC) or Crohn's disease (CD). The study will last about 172 weeks and may include up to 44 visits.
