Summary: Cholangiopathies are various biliary diseases that affect the biliary epithelium and can lead to cholestasis and liver cirrhosis. Primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC) are the most important progressive cholangiopathies in adults, with research focusing on genetic risk, epigenetic changes, dysregulated mucosal immunity, and altered biliary epithelial cell function. Understanding the molecular pathogenesis of these diseases can help clinicians prevent and treat them more effectively.

Summary: This study determined the performance characteristics of transpapillary biopsy sampling and fluorescence in situ hybridization in combination with standard brush cytology for diagnosing malignant biliary strictures. The findings suggest that trimodality sampling improves the diagnostic sensitivity for malignancy, but it is not superior to BC+FISH in patients with primary sclerosing cholangitis.

Summary: CCL24 is involved in fibrosis and inflammation in liver and its inhibition can reduce liver injury. This study found that blocking CCL24 improves inflammation, fibrosis, and cholestasis in PSC, and reduces proliferation and senescence of cholangiocytes.

Summary: This study found that approximately 20% of patients with chronic liver disease (CLD) develop progressive cholestasis after COVID-19 infection. Patients with NAFLD/NASH and metabolic risk factors are at higher risk of developing cholestatic liver failure and/or secondary sclerosing cholangitis (SSC) after COVID-19.

Summary: Some critically ill COVID-19 patients may experience significant and persistent cholestatic injury, with radiographic and histologic evidence of secondary sclerosing cholangitis, which could be a long-term sequelae of COVID-19 acute illness.

Summary: This study found that the prevalence of mAChR3inh+ auto-antibodies is significantly higher in both PBC and PSC patients. PBC patients with mAChR3inh+ auto-antibodies have higher levels of certain parameters and tend to have lower response rates to UDCA treatment. However, there are no significant differences in laboratory findings between PSC patients with and without mAChR3inh+ auto-antibodies.

Summary: Differentiation of benign and malignant biliary tract strictures on brush material remains challenging. This study compared brush samples from PSC-CCA and PSC-control subjects using NGS and found that the gene panel detected mutations in 15 of 20 PSC-CCA samples and in 3 of 20 PSC-control samples. The sensitivity of NGS was 75% and the specificity was 85%.

Summary: This study investigated the mechanistic relationship between telomere damage and biliary fibrosis in primary sclerosing cholangitis (PSC). The results showed telomere attrition and reduced telomerase reverse transcriptase (TERT) expression in patients with PSC. Cellular models demonstrated that telomere dysfunction can lead to senescence and fibrosis, which can be rescued by modulating TERT levels.

Summary: PSC is an immune-related cholangiopathy associated with high progression rates to end-stage liver disease and risk of various cancers. Emerging evidence suggests a link between gut microbiota and disease pathogenesis, with studies showing differences in the gut microbiome of PSC patients compared to healthy individuals and those with IBD. Further research is needed to understand the role of gut microbiota in PSC and related malignancies.

Summary: The study found that cellular senescence marker expression exists in cholangiocytes of PSC patients, which is related to the severity of the disease and patient outcomes. CS may serve as a new prognostic tool and potential therapeutic target in PSC.

Summary: Adding NGS to BB cytology and FISH in the evaluation of biliary strictures for patients with PSC may provide additional information that could help to inform clinical management, as NGS was better than FISH and cytology in detecting high-risk strictures, showing multiple genetic mutations in all cases, with reproducible results in longitudinal samples.

Summary: This study investigates the potential environmental contributors to autoimmune liver diseases (AILD) such as primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC). Significant spatial clustering of PBC and PSC patients was observed, with distinct risk profiles and associations with different environmental factors and socio-economic statuses identified. This suggests different triggers and alternative pathways determine the phenotypic expression of autoimmunity in the affected population.

Summary: Primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC) are two major autoimmune liver diseases. PBC primarily affects intrahepatic small bile duct epithelial cells in women, while PSC mainly affects medium and big bile duct epithelial cells in men. Cholangiocarcinoma (CCA) is a malignancy arising from cholangiocytes and is more prevalent in PSC patients than in PBC patients. Understanding the immune surveillance mechanisms that differentiate between PBC and PSC patients is crucial for developing effective therapies and early diagnosis of CCA.

Summary: Primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC) are two significant autoimmune liver diseases. PBC primarily affects small bile duct epithelial cells in women, while PSC predominantly affects medium and large intrahepatic and extrahepatic bile duct epithelial cells in men. Cholangiocarcinoma (CCA) is a malignancy arising from cholangiocytes and its incidence is increasing worldwide. Although PBC patients rarely develop CCA compared to PSC patients, understanding the differences in immune surveillance mechanisms is crucial for effective diagnosis and treatment.

Summary: The study found that ANZROD and APACHE III performed better in predicting in-hospital mortality in major trauma patients admitted to ICU compared to traditional trauma scoring systems. Performance of scoring systems was higher in younger adults than older adults, while anatomical scoring systems performed poorly.

Summary: This study characterized the patterns of opioid prescription after cardiac surgery. The results showed that opioid prescriptions at hospital discharge were common and often at higher doses than recommended. More than half of the prescriptions were slow-release formulations. Furthermore, 14.0% of patients were still receiving opioids 3-12 months after surgery.

Summary: Hepatocellular carcinoma (HCC) is a highly aggressive primary liver cancer and the third leading cause of cancer-related death worldwide. Recent years have witnessed an increasing number of treatment options for HCC, including both curative and non-curative therapies. However, these advancements have also posed challenges in disease monitoring, particularly in the early detection of HCC recurrence. This review will discuss and evaluate the current serological and radiological strategies for post-treatment monitoring and prognostication, as well as their limitations.
