Filter by:Primary sclerosing cholangitis (PSC) a rare, chronic fibroinflammatory disease of the liver. No data about the disease epidemiology exist in Italy. Therefore this study aims to develop a national PSC patient database linked to a biological sample storage.
This phase 2 trial will evaluate the effects of EP547 in subjects with cholestatic pruritus due to Primary Biliary Cholangitis (PBC) or Primary Sclerosing Cholangitis (PSC)
The investigators aimed to collect demographic features and clinical outcomes in patients diagnosed with PSC and IgG4-SC by utilizing participants database from multiple medical centers across Mainland China. Cross-sectional studies will focus on characterizing clinical presentations and validating diagnostic and prognostic models on Chinese PSC and IgG4-SC patients.
Primary sclerosing cholangitis (PSC) is a chronic progressive biliary disease that affects approximately 1200 patients in the Netherlands and around 80,000 in the Western world. It is often accompanied by ulcerative colitis (UC) or Crohn's disease affecting the large bowel. The cause of PSC is unknown, there is no medical therapy available that has proven to halt disease progression and the median time until death or liver transplantation is 13-21 years. Diagnosis is made by magnetic resonance cholangiography (MRC), or in the case of so called small duct disease by liver biopsy. Due to the heterogeneous disease course and the relatively low clinical event rate of 5% per year it is difficult to predict prognosis of individual patients or to recommend any surveillance strategy for malignancies. Also, the lack of surrogate endpoints impedes performing clinical research. Recently, two new post-processing tools have been developed to characterize and quantify abnormalities in the biliary tree as well as excretory function captured by MRC. These tools called MRCP+ (quantitative magnetic resonance cholangiopancreatography +) and LiverMultiscan (LMS) hold the prospect of adequately depicting and quantifying lesions of the biliary tree as well as capturing functional derailment. However, several features must be tested before the utility of this tools in clinical patient care can be concluded. Therefore, the aim of this study is to investigate the utility of these novel techniques in monitoring disease activity by performing consecutive annual MRI's.
This is a randomized, open-label, controlled, parallel group, multicenter clinical trial. Patients with confirmed secondary sclerosing cholangitis (SSC-CIP) will be randomized either in the intervention group undergoing scheduled invasive evaluation of the biliary tract or in the control group treated with non-interventional standard of care to demonstrate that programmed endoscopic therapy compared to a conservative strategy reduces the occurrence of treatment failures.
Primary sclerosing cholangitis (PSC) is the classical hepatobiliary manifestation of inflammatory bowel disease (IBD). Although rare, PSC is associated with significant and disproportionate unmet needs; with heightened risks of colorectal cancer and colectomy, and greater all-cause mortality rates compared to matched IBD patients. Unfortunately, no medical therapy has been proven to slow disease progression in PSC-IBD, and liver transplantation is the only lifesaving intervention for patients. The strong association between PSC and IBD has led to several pathogenic hypotheses, in which dysregulated mucosal immune responses are proposed to contribute. Of note, the investigators recently identified distinct mucosal transcriptomic profiles in PSC-IBD; with regards bile acid metabolism, bile acid signalling, and a central role of enteric dysbiosis. In parallel, pilot data from other groups have shown that treatment with oral vancomycin (a non-absorbable, gut-specific antibiotic) attenuates colonic inflammation and improves biochemical markers of cholestasis in PSC. However, there is no mechanistic data exploring the host-microbial alterations under vancomycin treatment in PSC-IBD, neither the impact of vancomycin on bile acid circulation. The investigators of this study hypothesize that oral vancomycin attenuates colonic mucosal inflammation in PSC-IBD, by restoring gut microbiota mediated bile acid homeostatic pathways. Through these means the study aims to identify druggable gut microbial and host molecular pathways associated with bile acid mediated colonic mucosal inflammation in PSC-IBD.
Primary sclerosing cholangitis (PSC) is a chronic progressive biliary disease. Due to the heterogeneous disease course and the relatively low clinical event rate of 5% per year it is difficult to predict prognosis of individual patients. Novel imaging techniques called MRCP+ and Liver Multiscan (LMS) hold the prospect of adequate depicting and quantifying lesions of the biliary tree as well as capturing functional derailment. However, these features must be tested first. The purpose of this study is to assess the (i) ability of MRCP+ to detect change in biliary volume, (ii) reproducibility of MRCP+ and LMS, and (iii) correlation of MRCP+ with ERC findings as gold standard.
Primary objective: To evaluate the efficacy of hymecromone plus standard of care compared with standard of care alone in the treatment of adolescents and adults with primary sclerosing cholangitis (PSC). Secondary objectives: To evaluate the change in Alkaline Phosphatase (ALP) from baseline to 6 months post-treatment following treatment with hymecromone plus standard of care compared with standard of care. To evaluate changes in biomarkers of PSC disease during hymecromone treatment, namely: (a) fibrotic effect (FibroScan); (b) inflammatory biomarkers (serum Hyaluronan (HA)); and, (c) T-cell count.
