Filter by:Aims:Prospectively observe the effects of Vitamin D drops supplementation on the chronic course of ulcerative colitis patients, analyze whether the effect of Vitamin D drops on UC patients is affected by factors such as disease site, disease activity, treatment, etc.Exploring the relationship between Fok I gene polymorphism and the efficacy of vitamin D supplementation. Provide a certain theoretical basis for "precision treatment" for UC patients in the future. Design：It is a prospective cohort study. Investigators include a total of 100 participants with UC according to the inclusion and exclusion criteria, and divide them into two groups to assess their initial disease activity and detect related indicators. At the same time，investigators detect the Fok I gene polymorphism in all participants.One group is given Vitamin D drops 400IU per day orally, and the control group do not intervene. Participants' disease activity is assessed at baseline and related indicators are determined. The disease activity is re-evaluated in the 3rd, 6th, 9th, and 12th months, and the serum indexes are re-evaluated.Investigators use statistical methods to analyze whether Vitamin D drops supplementation treatment can increase the serum 25 (OH) D level of UC participants, improve the condition of UC participants,relationship with Fok I gene polymorphism，and analyze the effects of Vitamin D drops on participants with UC is affected by factors such as disease site, disease activity, and treatment.
This is a Phase 2b, multi-centered, randomized, placebo-controlled trial with treatment phase over 24 weeks. Ulcerative Colitis (UC) is a condition that causes inflammation and ulceration of the inner lining of the rectum and colon (the large bowel). In UC, ulcers develop on the surface of the lining and these may bleed and produce mucus. Individuals with UC can become very unwell with disabling bloody diarrhoea, uncontrollable bowel habit and profound tiredness. In very severe cases, UC carry the risks of rupture of the inflamed bowel wall requiring an emergency operation to remove the colon. The MARVEL study investigates whether MitoQ is a beneficial drug treatment for UC. Earlier studies have shown that the inflamed UC gut lining releases 'danger signals' arising from the mitochondria. These 'danger signals' attract immune cells and make inflammation worse. Mitochondria are the 'batteries' or 'power stations' that reside within, and provide energy for living cells. In the gut lining of individuals with UC, the mitochondria are more prone to damage that increases the release of these danger signals. MitoQ protects the mitochondria and exerts an anti-inflammatory effect. The investigators hypothesise that MitoQ will improve UC and allow the bowels to heal properly following a disease flare. In the MARVEL study, individuals with an active flare of UC requiring standard oral Prednisolone will be given either MitoQ or placebo as a daily capsule for 24 weeks. The Investigators will carry out an assessment after 12 and 24 weeks to find out if MitoQ will result in higher rates of improvement in the participants' symptoms and gut lining inflammation. Furthermore, the investigators will investigate if their UC will be better controlled and that they are less likely to need further steroids or more potent forms of drugs. MitoQ has been shown to be safe in 2 large human clinical studies in Parkinson's disease and Hepatitis C, but the MARVEL study will be the first study in UC. At low doses, MitoQ is used as a nutritional supplement that has an anti-oxidant effect. Currently, many drug treatments in UC are very strong, expensive and aimed at suppressing the immune system. If the MARVEL study provides supportive data, MitoQ can be a safe and cost-effective new treatment that works at blocking the specific inflammatory signal found in the gut lining of individuals with UC.
The risk of colorectal cancer (CRC) is increased in patients having ulcerative colitis (UC). Patients with long-standing extensive colitis, concomitant primary sclerosing cholangitis, or previous history of dysplasia carry an exceptionally high risk of CRC and require regular and short-interval surveillance colonoscopy. Recent guidelines recommend surveillance colonoscopy based on target biopsy rather than random biopsy applying chromoendoscopy (CE) or narrow band image (NBI) technique in UC at risk for CRC. However, the diagnostic yield of NBI-based surveillance and CE-based surveillance is not extensively investigated in the high-risk UC population. The investigators aimed to compare the dysplasia detection rate of NBI with that of CE in UC patients with a high risk of CRC by performing a multicenter, randomized controlled trial.
The aim of this study is to evaluate the evolution and possible factors associated with the persistence of fatigue in patients with quiescent IBD and fatigue included in two previous studies.
Partial response or loss of response to golimumab is observed in a significant proportion of patients started on golimumab for active ulcerative colitis. The current dosing regimen in European Union is based on patients' body weight as maintenance treatment for patients with ≥ 80 kg is 100 mg q4 weeks and for patients with <80 kg 50 mg q4 weeks. The investigators recent observations in a golimumab pharmacokinetics study of 24 patients however, show large interindividual variations in golimumab trough concentrations. Furthermore, it seems that patients with continuous response have higher golimumab trough levels at several time points during treatment compared to patients who lose response. Higher induction/maintenance dose of golimumab increases golimumab trough levels, therefore it is likely that higher induction/maintenance dose of golimumab would increase efficacy of golimumab treatment.
This study aims to assess the safety and efficacy of heterologous fecal microbiota transplantation (FMT) by Standardized Quantitative multi-donor Intestinal Microbiota Capsule (SQIMC-md) in mild-moderate ulcerative colitis patients who fail to achieve clinical remission over 4 weeks after full dose 5-Aminosalicylic acid(5-ASA). Intestinal microbiota transplant for FMT will be prepared from multiple healthy donors and prepared by standardized procedure with fixed quantitative dosage. This strategy might offer a novel and safe therapeutic approach for these patients before step up to corticosteroid, immunosuppressant or biologics therapy.
By capturing possible or known risk factors, it will be possible to recognize connections between these risk factors and the disease, thus obtaining valuable insights into the cause of the disease. This in turn facilitates an improved evaluation of the treatment situation as well as influencing future framework conditions for preventive measures and planning treatments. Disease registries are thus crucial for the planning and structuring of health policies. The present registry protocol serves as a basis for the proper implementation of a registry for patients with chronic inflammatory bowel diseases. It describes the study rationale, objectives, design, participant groups, procedures and evaluation methods. Furthermore, it defines the responsibilities of each person involved in maintaining the registry and also forms the basis for decisions regarding evaluation by the Ethics Committee.
The aim of this study is to determine the efficacy and safety of Beta-1,3/1,6-D-Glucan from mycelium extract of Ganoderma lucidum on ulcerative colitis
This pilot study aims to evaluate the effect of a 16-week duration of multistrain probiotic product (De Simone Fomulation (DSF), previously known as VSL#3 and now available as Vivomixx in EU and Visbiome in USA to reduce anxiety and depression scores in mild to moderate active UC. It has been known that gut microbiota is associated with IBD and mental health. In addition, IBD patients complicated with psychiatric disorders are rising more and more attention. Further, a recent study "Probiotic Bifidobacterium longum NCC3001 Reduces Depression Scores and Alters Brain Activity: A Pilot Study in Patients With Irritable Bowel Syndrome" was published in Gastroenterology in 2017, thus we wonder if DSF have an effect on the depression/anxiety in patients with UC）A total of 60 patients will be randomly allocated into two groups, group A will receive standard medical therapy plus placebo (4 sachets/day,), and group B will receive standard medical therapy plus DSF (each sachet containing 450 billion CFU, eight bacterial strains 4 sachets/day) for 16 weeks. The primary endpoint is the reduction of anxiety and depression scores after treatment (at 8 weeks and 16 weeks) using hospital anxiety and depression scale (HADS). The secondary endpoints including clinical response after 8-week and 16-week treatment (measured by a ≥3-point reduction in a Simple Clinical Colitis Activity Index (SCCAI) score at 16 weeks), and clinical remission (defined as SCCAI score ≤5 at 8 weeks and 16 weeks). Changes in fecal-associated microbiota by 16S ribosomal RNA sequencing and metabolomics using company service following probiotics therapy (at 16 weeks) were also assessed, stratified by both change in SCCAI score following probiotics therapy and randomization. Adverse events were evaluated at week 8 and 16 weeks by patient survey
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.
