Filter by:Ulcerative colitis (UC) is a chronic relapsing inflammatory bowel disease. UC pathogenesis remains poorly understood but involves an inappropriate immune response toward an unbalanced gut microbiota (called dysbiosis) in predisposed hosts. The purpose of this study is to determine the effect of the fecal microbiota transplantation on UC.
This is a prospective observational cohort study, over 52 weeks, evaluating the the use of faecal microbiota transplantation amongst patients with Inflammatory Bowel Disease and Microscopic Colitis
Ulcerative colitis (UC) belongs to the group of inflammatory bowel disease (IBD) and is characterized by a chronic relapsing disease course. As uncontrolled intestinal inflammation can lead to severe disease complications, treatment of UC has evolved from sole treatment of symptoms up to histological remission which is marked by the absence of histological inflammation. To correctly assess and quantify the degree of histological inflammation in IBD patients remains difficult. Digital holographic microscopy (DHM) is a new imaging technique belonging to quantitative phase contrast imaging. It is based on the detection of optical path-length delays in a stain-free manner, thereby providing a refractive index which directly correlates to tissue density. This study aims to evaluate the role of DHM for quantifying the degree of histological inflammation in endoscopically acquired biopsies of UC patients in a prospective clinical trial. From 28 UC patients, the investigators will obtain endoscopically acquired colonic biopsies. The investigators will assess the degree of inflammation in these biopsies using DHM and in addition to this an experienced histopathologist will determine the degree of inflammation in these biopsies using a histological scoring system (Nancy-Score = goldstandard). Finally, the investigators will directly correlate the results from DHM analysis to the histological analysis using the Nancy-Score.
Epidemiological studies suggest that daily intake of fruits and vegetables high in polyphenols or the addition of olive oil containing many polyphenols is associated with a reduced risk of chronic diseases including cardiovascular, metabolic, neurodegenerative, and inflammatory bowel conditions. In vivo experiments demonstrated that the administration of a diet associated with daily intake of extra virgin olive oil (EVOO) reduces histological lesions and symptomatology in rats with a dextran sulfate sodium (DDS) induced colitis. A diet supplemented with hydroxytyrosol (a component of olive oil) showed a reduction of the inflammatory process at the inflamed colon of the rats.
TNF inhibitors have improved treatment options for patients with inflammatory bowel disease (IBD) and three TNF inhibitors, infliximab, adalimumab and golimumab are available for treatment of ulcerative colitis in Switzerland. However, these drugs have been tested under ideal conditions in randomized controlled trials. Real-world data are needed to complement this information. It is the aim of our study to test, whether patients with ulcerative colitis can be effectively treated with golimumab in a real world setting in Switzerland. The investigators will use data from the Swiss IBD cohort study (SIBDC) in Switzerland. They will identify all SIBDC patients with UC treated with Golimumab and perform a retrospective chart review. The investigators will acquire patient reported outcomes and objective measures for inflammation at baseline, at 6-10 weeks and at 6 and 12 months after golimumab treatment. Primary endpoint will be clinical response (i.e. meaningful improvement) at 6-10 weeks. Secondary endpoints will be clinical response at 6 and 12 months and clinical remission (i.e. free of symptoms of disease).
Fecal Microbiota Transplantation(FMT) - reconstitution of normal flora by a stool transplant from a healthy individual, is increasingly being recognized as a therapeutic modality for diseases that are associated with gut dysbiosis. This is a placebo-controlled, double blinded interventional study evaluating multiple, oral, fecal microbiota transplantation, administered in newly diagnosed adult patients with mild-moderate UC. The primary objective is to assess the safety and feasibility of multiple, oral, fecal microbiota transplantation,in newly diagnosed adult patients with mild-moderate UC. All processing will occur at the Center for Microbiome Research at Assaf Harofeh Medical Center, under GMP conditions.
TARGET-IBD is a 5-year, longitudinal, observational study of adult and pediatric patients (age 2 and above) being managed for Inflammatory Bowel Disease (IBD) in usual clinical practice. TARGET-IBD will create a research registry of patients with IBD within academic and community real-world practices in order to assess the safety and effectiveness of current and future therapies.
The purpose of this study is to assess the effect of vedolizumab intravenous IV as induction and maintenance treatment in Chinese participants with moderately to severely active ulcerative colitis (UC).
Helicobacter pylori (H. pylori) infection is one of the most common infectious diseases in humans.
We analyzed the diversity of the fungal and bacterial within colon mucosa between patients with different degree of inflammation of Ulcerative Colitis.
