Active clinical trials for "Cholangitis"

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.

The investigators hypothesize that PSC in children is associated with mutations and functional changes of the cystic fibrosis (CF) gene.

This study aim to prospectively evaluate the clinical utility of Spyglass in sclerosing cholangitis patients undergoing endoscopic retrograde cholangiopancreaticography (ERCP). Fifty patients with a definite diagnosis of sclerosing cholangitis and a clinical indication for ERCP from September 2008 and onwards will be investigated with peroral cholangioscopy using Spyglass direct visualization system. Clinical data on all patients will be collected at time of the ERCP including information on the Primary sclerosing cholangitis (PSC) and inflammatory bowel disease (IBD), serum liver function tests and indication for ERCP. A structured data collection form including information on Majoie Score, macroscopic features of the bile ducts at cholangioscopy, quality of the investigation, technical difficulties, and an overall judgment of whether any abnormalities observed were benign or malignant was completed by the endoscopist in conjunction with the procedure.

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.

To explore differences in patients, techniques and outcomes across the international cohort to identify areas of practice variability in the presentation and management of acute complicated calculous biliary disease.

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.

A randomized controlled trial to determine the optimal placement duration of pancreatic duct stents (PDS) inserted during ERCP: 2 vs 4 weeks

Retrospective study to analyze benign complications and malignancy risks after ERCP with sphincterotomy. All patients who received a ERCP with sphincterotomy for a benign disease will be included. Post-ERCP hepato-biliary complications in the follow-up will be registered.

The aging of the population goes along with an increased demand for intensive care among very elderly patients (above 75-80 years old). At the same time, there is a decline in the supply of intensive care units (ICU). The 1-year mortality of patients above 80 years old in ICU ranged from 40 to 70%. Moreover, many survivors suffer from long-term sequelae as poor quality of life, cognitive impairment and functional disability. It is unclear under what conditions older patients may benefit from ICU admission. Cholangitis frequently occured in older patient. Moreover, severe acute cholangitis is a potentially life threatening disease characterized by a biliary obstruction and an infection of the bile possibly evolving towards systemic infection, shock and death. Because of its potential rapid reversibility of symptom thanks to early intravenous antibiotics and biliary decompression with drainage, old patients suffering from acute cholangitis are easily admitted to intensive care unit. To date, there is a lack of data about the outcome in this population admitted to the intensive care unit with acute cholangitis. The aim of the current study is to describe the outcomes in elderly patients (> 75 years old) admitted to the ICU with acute cholangitis and to identify prognostics factors associated with long term mortality (6 months).

This observational study of a national cohort of 600 Swedish PSC patients include yearly MR/MRCP, biobanking of serum, plasma and blood, followup clinical data (interventions, symptoms, labs, colonoscopy). The aim is to collect a well characterized cohort of PSC patients and provide future possibilities to evaluate biomarkers for prognosis and early cancer detection.
