Filter by:Explorative investigation to study the effect of the endogenous bacterium Lactobacillus reuteri ATCC PTA 4659 as a nutrient additive against relapse in ulcerative colitis. Forty patients will be studied with a randomized parallel design over one year. Patients with established treatment against relapse of ulcerative colitis with mesalazine ≤4 grams will be requested to participate in the study, allocated to 20 patients with placebo and 20 with active treatment L. reuteri as an "add-on". Inklusion: 18-80 years of age, ≥1 relapse with bleeding during previous 12 months with a disease activity Mayo Clinical Score ≤2, treatment with mesalazine ≤4,0 g daily. Exklusion: >80 years of age, no registered bleeding during recent 12 months, on-going steroid treatment, immunosuppressives, biologics or adhesion inhibitors, antibiotics or other clinical trial. behandling med probiotika. Disease monitoring will be done with: Time to disease relapse with macroscopic bleeding and Mayo score ≥5, blood chemistry and CRP, lipopolysaccharides and gut permeability, fecal calprotectin, and short health scale at 4 weeks, 26 weeks and 52 weeks.
The aim:1) To test the correlation of pCLE-obtained features with histological findings in UC; comparing the real-time conventional colonoscopy Baron score with CLE assessment. 2) To test the accuracy of the investigators previously proposed simplified four-grade classification system of crypt architecture in evaluating inflammation activity in UC by pCLE.
Muscle and physical activity play an important role in in growth, development and bone health in healthy children, especially during puberty. Children with inflammatory bowel disease (IBD) have lower level and intensity of physical compared to a control group. Several studies have shown that children with IBD have a lower bone mineral density (BMD) than general population, due to risk factors such as corticosteroid use, disease intensity, inflammation, malnutrition and a vitamin D deficiency. This low BMD is associated with an increased risk of fracture. A recent observational study found a positive and significant correlation between BMD in IBD patients and time spent in moderate to vigorous physical activity for one week (unpublished data).The present study aims to show a benefit of an adapted physical activity program on BMD in children and adolescents with IBD.
The cause of Inflammatory bowel disease (IBD) is unknown, but intestinal bacteria-involved in the production of molecules that impact health-are widely accepted to play a key role. A significant proportion of IBD patients with pouches (surgically created rectums after the diseased colon is removed) continue to have inflammation similar to their previous disease. Only a few microbes are known to have the capability to modify primary bile acids (PBAs) made by the liver to secondary bile acids (SBAs). SBAs are some of the most common metabolites in the colon and play key roles in several diseases. In this study the investigators will investigate if ursodeoxycholic acid (UDCA) may reduce inflammatory markers and improve quality of life (as assessed by validate survey) in those subjects with active antibiotic refractory or antibiotic dependent pouchitis.
Ulcerative colitis is a chronic idiopathic inflammatory disease of the colon that is characterized by abdominal pain and bloody diarrhea. The pathogenesis of UC involves a complex interplay of genetic factors, immune dysregulation and environmental triggers. Conventional therapies for UC (including 5-aminosalicylates, corticosteroids, azathioprine or 6-mercaptopurine and biologics) focus on altering the immune response by suppression of immune cells. However, the primary pathogenic mechanism underlying UC maybe gut microbiota dysbiosis and a dysfunctional intestinal barrier resulting in an aberrant host immune response. Several studies have shown reduced microbial diversity in UC patients with under representation of anti-inflammatory phyla (Bacteroides and Firmicutes), and a relative increase of pro-inflammatory phyla (Proteobacteria and Actinobacteria). Motivated by this, therapies targeting intestinal dysbiosis (prebiotics, probiotics, synbiotics and fecal microbiota transplant (FMT)) have thus been tried in patients with UC. Though several case series and subsequently four high quality randomized controlled trails have established the efficacy of FMT in induction of remission in active UC, all these studies have used it as an add-on therapy, along with the previously ongoing conventional therapies. The investigators aim to assess the safety and efficacy of FMT as the sole modality for induction of remission in patients with newly diagnosed active UC.
Mucosal healing or histological remission is an important target for the treatment of inflammatory bowel disease. In this study, patients with mucosal healing are defined as a control group, observing their clinical outcomes for 3 years, and describing the recurrence rate. The secondary objective is to study the operative rate, glucocorticoid utilization rate, treatment escalation rate, hospitalization rate and incidence of related complications.
The aim of this study is to assess the ability of miR-320a and other specific microRNAs to follow the disease course in patients with Crohn`s disease (CD) and ulcerative colitis (UC), and to distinguish both entities, infectious colitis and healthy controls. Furthermore, the accuracy of miRNA-320a to distinguish CD or UC from irritable bowel syndrome (IBS) should be evaluated . The study is designed as a single center non-randomised prospective trial.
Ulcerative colitis (UC) is a chronic inflammatory bowel disease (IBD) that results from immune dysregulation. Arguably, the development of Tumor Necrosis Factor (TNF) antagonists (including infliximab, adalimumab and golimumab) revolutionized the management of immune-mediated chronic diseases in the past two decades. However, about one third of patients will not respond to a first anti-TNF treatment and 10% to 30% will loose response to anti-TNF during the follow-up. Historically, a switch between anti-TNF was performed to recapture remission and response to anti-TNF. Recently, a new biologic therapy blocking another target has been approved and is now reimbursed during ulcerative colitis, namely vedolizumab. Vedolizumab is an anti-integrin agent avoiding the recruitment of lymphocytes specifically in inflamed gut tissue. Emerging data suggest that a switch of therapeutic class (meaning a change of biologic target with Non-TNF-targeted biologic) in case of clinical failure or insufficient response to anti-TNF may be the best choice. This idea of a switch out of the anti-TNF class is also supported by data on drug monitoring that may help physician decision making in case of loss of response. However, no trial is currently available and ongoing to assess the best therapeutic strategy. The aim of the proposed study is to assess the best biological based strategy in patient losing response to a first subcutaneous anti-TNF (golimumab and/or adalimumab).
Ulcerative colitis (UC) is a chronic, progressive immunologically mediated disease affecting nearly 1 million Americans. Up to one third of patients with UC will require hospitalization for severe disease (termed 'acute severe colitis (ASUC)'), often within the first year after diagnosis. Investigators will develop a large multi-center cohort of patients with ASUC with homogeneously collected detailed longitudinal clinical and laboratory data.
The purpose of this study is to see how a diet that mimics fasting effects inflammation in patients with mild to moderate Ulcerative Colitis (UC). The diet may allow users to receive the benefits of fasting while also being able to enjoy food (the ingredients of which are GRAS (generally recognized as safe) by the Food and Drug Administration (FDA). Research on dietary interventions and UC are very limited. Fasting mimicking diets (FMD) have been studied with support of the National Institute of Health and published in leading journals. This research investigates whether markers of inflammation decrease and/or quality of life increases after three cycles of a five-day period of the fasting mimicking diet, and may provide rationale for its use to treat UC.
