Active clinical trials for "Liver Cirrhosis, Biliary"

Fatigue is a clinical symptom that has been described as the most disturbing by around 50% of patients with PBC. It has an important impact on patients' quality of life and is associated with an increased mortality risk. To treat fatigue in PBC, only medical treatments have been tested with limited efficacy or serious sides' effects. In other diseases, mostly cancer, psychological interventions showed efficacy on fatigue decrease. Most interventions consist in psychoeducation with: education about fatigue, development of self-care or coping techniques, activity management and learning to balance between activities and rest. Hypnosis, which consists in a body work for psycho-therapeutic use (e.g., through imagination), has also shown promising results. Moreover, psychological intervention efficacy seems to be influenced by patients' characteristics, such as personality. Therefore, the first aim of the present single-center randomized controlled phase 2 trial is to assess the efficacy of a psycho educational intervention and a hypnosis intervention on PBC patients' fatigue to demonstrate that both psychoeducational and hypnosis interventions decrease patient fatigue.

This is an observational, retrospective cohort study, using the UK PBC registry, comparing patients with primary biliary cholangitis (PBC) who failed ursodeoxycholic acid (UDCA) treatment and were treated with obeticholic acid (OCA) to patients with PBC who failed UDCA treatment and were not treated with second-line therapy. The study is designed to evaluate the effectiveness of OCA. All patients who meet diagnostic criteria for PBC in the database between 01 Jun 2015 and 31 Dec 2021 and who meet all eligibility criteria will be considered for this study.

This case control study aims to determine whether spontaneous coronary artery dissection (SCAD) is associated with autoimmune diseases and to update the incidence of SCAD in a population-based cohort.

This study evaluates the different response of Ursodeoxycholic Acid in primary biliary cholangitis only and primary biliary cholangitis with high immune globulin G or aminotransferase at West China Hospital from 2008-2017.

Retrospective study of all patients diagnosed with primary biliary cholangitis during January 2001 to July 2016 at West China Hospital by review of medical records. The following variables will be retrospectively studied: age, sex, first symptoms, clinical characteristics, pathology, treatment, stage, complications of cirrhosis, other autoimmune diseases and long-term outcome.

This study aims to determine the repeatability and reproducibility of Quantitative Magnetic Resonance Cholangiopancreatography (MRCP). Imaging scientists at Perspectum Diagnostics have developed a hessian-based mathematical model to enhance conventional MRCP to a 3D geometric model of the biliary tree, 'Quantitative MRCP'. This enables advanced quantitative measurement of bile duct width, orientation, branching point and curvative metrics. The technology has been validated against 3D printed phantoms for accuracy, and early clinical research has demonstrated the technology has potential for clinical impact, with improvement in radiologist performance versus conventional non-enhanced MRCP imaging (Vikal et al 2017). Quantitative MRCP aims to act as a tool to not only improve assessment of the current status of the biliary tree, but also act as a mechanism to track change within the ducts. Thus, it must be established that any change between scans is due to change in the physiology of the individual and not due to a quirk or fault of the technology. In order to achieve this a series of scans will be performed on an individual over a short period of time, for which the condition of the biliary tree within that individual can be assumed to be constant. Between each scan, subject and coil repositioning will occur. The study will recruit a group of adult volunteers, from both diseased groups and healthy groups in order to achieve a range of physiological biliary metrics.

Primary biliary cholangitis (PBC) is a chronic inflammatory liver disease leading to cirrhosis. Researches reported patients with PBC may involve abnormalities on skeleton, thyroid and exocrine glands. However, whether this autoimmune disease would cause cardiac impairment is scarcely investigated. Cardiovascular Magnetic Resonance(CMR) is recently developed as a reliable modality to evaluate the cardiac tissue characteristics and functions. This study aims to investigate the cardiac status in PBC patients based on CMR.

To compare intestinal flora diversity in different PBC patients with UDCA responses, and further study the differences of bile acid metabolism and short chain fatty acid metabolism in feces and serum of two groups of PBC patients.

Primary biliary cirrhosis (PBC) is a progressive autoimmune disease of biliary epithelial cells resulting in biliary cirrhosis. PBC is characterized by a 90% female predominance, high titers of serum anti-mitochondrial autoantibodies (AMA) directed against the pyruvate dehydrogenase complex E2 subunit and evidence from both human and murine models suggests that T-cells, particularly cluster of differentiation (CD) 8+ T cells, are key to the destruction of bile ducts. However, clinical trials of classic immunosuppressive drugs including corticosteroids, azathioprine, methotrexate, and tacrolimus have been largely unsuccessful in altering the disease course. This is a single center, prospective, non-treatment study of the role of immune responses in PBC patients. Non-alcoholic fatty liver disease (NAFLD) and its more severe form, non-alcoholic steatohepatitis (NASH) are common, often "silent" liver diseases. NASH resembles alcoholic liver disease, but occurs in people who drink little or no alcohol. The major feature in NASH is fat in the liver, along with inflammation and fibrosis. NASH can be severe and can lead to cirrhosis and hepatocellular carcinoma. Ten to 20 percent of American have NAFLD with NASH affecting 2 to 5 percent of Americans.

PBC is a rare, autoimmune, cholestatic liver disease with genetic and environmental pathogenetic factors. Data about epidemiology of PBC in Switzerland are completely lacking. Epidemiology can be a powerful tool in yielding important clues as to burden and etiology of diseases. In addition, the investigators study will be the first one carried out in the country on PBC, and therefore will raise disease awareness and create a network.
