Primary sclerosing cholangitis is one of the most challenging conditions in hepatology, and due to our limited understanding of its pathogenesis, no causal therapies are currently available. While it was long assumed that a minority of people with IBD also develop PSC, which is sometimes labeled an extraintestinal manifestation of IBD, the clinical phenotype, genetic and intestinal microbiota associations strongly argue for PSC-IBD being a distinct form of IBD, existing alongside ulcerative colitis and Crohn's disease. In fact, the liver itself could contribute to intestinal pathology, clinically overt in 60 - 80 % of patients.

Background: We conducted a single-arm interventional study, to explore mucosal changes associated with clinical remission under oral vancomycin (OV) treatment, in primary sclerosing cholangitis associated inflammatory bowel disease (PSC-IBD); NCT05376228.

Method: Fifteen patients with PSC and active colitis (median faecal calprotectin 459µg/g; median total Mayo score 5) were treated with OV (125mg QID) for 4 weeks and followed-up for a further 4 weeks of treatment withdrawal (8 weeks, end-of-study). Colonic biopsies were obtained at baseline and week 4.

Specialized or secondary metabolites are small molecules of biological origin, often showing potent biological activities with applications in agriculture, engineering and medicine. Usually, the biosynthesis of these natural products is governed by sets of co-regulated and physically clustered genes known as biosynthetic gene clusters (BGCs). To share information about BGCs in a standardized and machine-readable way, the Minimum Information about a Biosynthetic Gene cluster (MIBiG) data standard and repository was initiated in 2015.

Article Synopsis
  • Primary sclerosing cholangitis (PSC) is a progressive liver disease without effective medical treatments, but new clinical trials are exploring innovative therapies despite varying outcomes and measurement inconsistencies.
  • There is a shift in treatment goals towards assessing liver fibrosis and patient-reported outcomes, indicating a need for a standardized approach to measure treatment effects across trials.
  • The development of a core outcome set (COS) will involve a systematic literature review, stakeholder interviews, a Delphi survey for prioritizing outcomes, and a consensus meeting to establish effective measures for future PSC clinical studies.

Background And Aims: The UK low-risk drinking guidelines (LRDG) recommend not regularly drinking more than 14 units of alcohol per week. We tested the effect of different pictorial representations of alcohol content, some with a health warning, on knowledge of the LRDG and understanding of how many drinks it equates to.

Design: Parallel randomized controlled trial.

Introduction: The impact of living with Primary Sclerosing Cholangitis (PSC) on psychological wellbeing is not well-known. A recent scoping review by the authors found that both depression and anxiety frequently featured in the accounts of those living with the illness. However, less clear were the factors that led to such psychological distress, the impact that the illness had on families and how to best support those living or supporting someone living with the illness.

Introduction: Primary sclerosing cholangitis (PSC) is a rare and chronic disease characterised by inflammation and fibrosis of the liver's bile ducts. There is no known cause or cure for the illness, which often progresses to end-stage liver disease requiring liver transplantation. Symptoms of PSC can be very burdensome on those living with the illness, leading to restrictions in daily living, as well as a greater risk of colorectal and biliary tract cancers.

Article Synopsis
  • * We identified key clinical variables, such as serum alkaline phosphatase levels and extrahepatic biliary disease, that strongly predict 10-year outcomes, leading to the creation of two effective risk scoring systems.
  • * Our new UK-PSC risk scores successfully predicted outcomes better than existing models, and while a specific genetic risk allele was associated with worse outcomes, it didn’t enhance the accuracy of our scores.

Primary sclerosing cholangitis (PSC) is a chronic liver disease resulting from the inflammation and scarring of an individual's hepatic bile ducts. With no curative treatment available and a risk of potentially severe complications and death, it is likely that those diagnosed with the illness may experience impairments in their psychological wellbeing. The aim of this scoping review is to locate, chart, and summarize all available literature on how PSC affects mental health and psychological wellbeing, as well as the factors that may or may not impact on the psychological wellbeing of those who have this diagnosis.

Key Points: Tenascin-X (TNX) is an extracellular matrix glycoprotein with anti-adhesive properties in skin and joints. Here we report the novel finding that TNX is expressed in human and mouse gut tissue where it is exclusive to specific subpopulations of neurones. Our studies with TNX-deficient mice show impaired defecation and neural control of distal colonic motility that can be rescued with a 5-HT receptor agonist.

Primary biliary cholangitis (formerly known as primary biliary cirrhosis, PBC) is an autoimmune liver disease in which a cycle of immune mediated biliary epithelial cell injury, cholestasis and progressive fibrosis can culminate over time in an end-stage biliary cirrhosis. Both genetic and environmental influences are presumed relevant to disease initiation. PBC is most prevalent in women and those over the age of 50, but a spectrum of disease is recognised in adult patients globally; male sex, younger age at onset (<45) and advanced disease at presentation are baseline predictors of poorer outcome.
