Summary: In this retrospective study of 82 patients who underwent liver transplantation for primary sclerosing cholangitis (PSC), the authors assessed morbidity, survival rates, PSC recurrence, and the impact of donor characteristics in long-term follow-up. The study showed that PSC patients had excellent 10-year survival rates and a lower lab-MELD score was associated with longer survival. Donor characteristics did not affect patient survival.

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: UDCA after LT reduces the odds of BC and bile stones and sludge in all-comer LT recipients and reduces or delays the incidence of rPBC in patients transplanted for PBC. UDCA use after LT could be considered in all LT recipients to reduce the odds of BC and may be particularly beneficial for patients transplanted for PBC by reducing the incidence of rPBC.

Summary: Comparative analysis of gut microbiome and metabolome in IgG4-SC and PSC patients revealed distinct host-microbe interactions that may contribute to disease pathogenesis, highlighting the uniqueness of IgG4-SC.

Summary: The number of liver transplantation for primary biliary cholangitis (PBC) has decreased over the years, but it remains an important and curative option for progressive PBC patients. Recent studies from the Global PBC Study Group have provided valuable insights into the changes in PBC before and after liver transplantation.

Summary: This retrospective trial used national data to examine the characteristics and outcomes of patients hospitalized with overlapping PBC and AIH. The study found that PBC/AIH patients had lower rates of Crohn's disease, higher rates of Sjogren's syndrome, higher rates of cirrhosis-related complications, and significantly increased risk of septic shock compared to PBC and AIH individually.

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 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: This retrospective study evaluated risk factors for rPSC in 140 children and found that patients with rPSC were younger at LT, had faster progression from PSC diagnosis to LT, and had a higher prevalence of inflammatory bowel disease. rPSC subjects experienced more episodes of acute rejection, complications of portal hypertension, and higher mortality rates post-LT.

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: Several studies have shown that patients with PBC have an increased risk of developing HCC. Risk factors for HCC in PBC include advanced age, male sex, comorbidities, and advanced liver fibrosis. The role of treatment response as a risk factor for HCC development in PBC patients should be further investigated. HCC in PBC has a poor prognosis compared to other chronic liver diseases with HCC, and liver transplantation offers the highest survival rate among available therapies.

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 compares the outcomes of living donor liver transplant (LDLT) and deceased donor liver transplant (DDLT) in patients with primary biliary cholangitis (PBC). The results show that LDLT has superior patient survival compared to DDLT, and there is no significant difference in graft survival between the two methods. The study also identifies predictors of poor post-transplant outcomes in PBC patients.
