Filter by:Ulcerative colitis (UC) is one of the most common types of chronic and non-specific inflammatory bowel diseases (IBD). It is characterized by cytokine-induced continuous and diffuse inflammatory infiltrations into the rectum's mucosa and extends proximally to the colon. Patients with UC predominantly have bloody diarrhea, abdominal pain, fecal urgency, and tenesmus, which extremely alters their quality of life. Although the precise pathological mechanism of UC remains unclear, several studies have been outlined many factors that could involve in the pathogenesis of UC, including, but not limited to, initiation of the inflammatory response, disruption of oxidant/antioxidant status, dysregulation of the immune response, alteration of gut microbiota, and delaying epithelial barrier healing. Loss of intestinal barrier function and dysregulated immune response are the key events during colitis development
The role of intestinal ultrasound in treatment monitoring has recently gained increasing interest thanks to its non-invasiveness, cost-effectiveness and largely availability. Moreover, new ultrasonographic tools, particularly dynamic contrast-enhanced ultrasound (D-CEUS) and shear wave elastography (SWE) can provide further useful information, such as a quantitative estimation of bowel intramural microvacularization and tissue stiffness. Aim of this study is to evaluate the role of D-CEUS and SWE in predicting deep remission at 12 months from treatment induction in IBD.
HLA-DQA1*05 variant carriers are at risk of developing antibodies against infliximab and adalimumab with reduced TNF antagonist persistence. The impact of proactive therapeutic drug monitoring (PTDM) on this association has been barely assessed. Therefor, we propose a cohort study including adult patients with Crohn's disease and ulcerative colitis treated with TNF antagonists under proactive therapeutic drug monitoring. Our hypothesis is that, proactive therapeutic drug monitoring could be an alternative to combination treatment with immunomodulators to increase TNF-antagonists' persistence in HLA-DQA1*05 carriers.
The inflammatory bowel diseases (IBD) are described as complex, recurrent inflammatory conditions which are manifested as Crohn's disease (CD) and ulcerative colitis (UC). The common symptoms of IBD include debilitating/severe diarrhea, abdominal pain, weight loss, and chronic fatigue; events that may culminate in life-threatening complications. The pathogenesis of IBD has been characterized as complex/multi-factorial that includes disruption of intestinal epithelial barrier with consequent translocation of commensal microbial products as the prime event that instigates severe immune responses and intestinal inflammation.
The effects of diet on inflammatory bowel disease is an under-studied area of research. The investigators are interested in further investigating the role that diet contributes to inflammatory bowel disease severity. The investigators will collect blood and stool samples from patients with inflammatory bowel disease (IBD) before and after diet changes. The stool samples will be analyzed using metabolomics and microbiome analysis to determine changes after the new diet has been implemented. The investigators will then compare changes in the patient's overall disease state by measuring markers of inflammation including C-reactive protein (CRP) and fecal calprotectin to determine how this diet affects the disease state.
PSC is a liver disease that has no medical cure. Patients with PSC are at a greatly increased risk of cancer and infection. Additionally, many patients require a liver transplant. Progress towards a cure has been severely limited by an incomplete understanding of why patients develop PSC. The investigators aim to close this gap by conducting a pilot human study in patients with PSC, using statin therapy as a model
This study is examining fatigue in patients with Inflammatory Bowel Disease (IBD). IBD includes Ulcerative Colitis (UC) and Crohn's disease. These are inflammatory conditions of the gastrointestinal tract and are associated with symptoms including diarrhoea, rectal bleeding and abdominal pain. Fatigue is a common problem for patents with IBD, affecting 80% of patients with active disease.This study aims to identify all IBD patients with fatigue. Initially, the investigators will address all medical causes of fatigue in line with current practice, using a stepwise approach (e.g. assessing for and treating active inflammation, anaemia as well as electrolyte, hormone and vitamin imbalances). The aim is to treat fatigue using a detailed algorithm, as fatigue is often a consequence of multiple issues in IBD patients. The investigators will assess the role of physical activity, nutritional status and psychological wellbeing in fatigue persisting in medically-optimised IBD patients. In addition, the contribution of the microbiome to fatigue will be assessed. For those in whom these factors are identified alongside persistent fatigue, interventions have been designed to address these factors and the resulting fatigue.
Crohn's disease (CD) and ulcerative colitis (UC) are chronic inflammatory bowel diseases (IBD) with a heterogeneous disease course. Recurrent mucosal inflammation or chronic subclinical inflammation results in damage to the bowel and complications like stenosis, fistula and colorectal cancer. Therefore, tight control of mucosal inflammation is important to prevent complications. The goal of this multicenter observational cohort study is to determine the best remote monitoring tool for predicting mucosal inflammation in adult patients with inflammatory bowel disease, relative to the gold standard endoscopy. Participants will be asked to fill out questionnaires regarding disease activity (MIAH, mHI, IBD-control, Manitoba IBD Index, p-HBI/p-SCCAI), perform a FC home test and collect one stool sample for routine laboratory calprotectin measurement, before the start of the bowel preparation for the ileocolonoscopy. During this ileocolonoscopy, endoscopic disease activity will be determined. .
The purpose of this study was to evaluate the association between gallstone disease and the risk of inflammatory bowel disease.
Primary sclerosing cholangitis (PSC) is chronic fibroinflammatory disease of the liver. There is still no medical therapy proven to halt the progression of PSC or prevent its serious complications. This is a Phase 2 randomized, double bind, placebo-controlled, monocentric study evaluating the safety and efficacy of two doses of oral vancomycin (i.e. 750 mg and 1500 mg/day) in subject between 15 - 70 years old with PSC.
