Primary sclerosing cholangitis (PSC) and Primary biliary cholangitis (PBC) are chronic inflammatory biliary diseases characterized by progressive damage of the bile ducts, resulting in hepatobiliary fibrosis and cirrhosis. Currently, specific biomarkers that allow to distinguish between PSC and PBC do not exist. In this study, we examined the salivary proteome by carrying out a comprehensive and non-invasive screening aimed at highlighting possible quali-quantitative protein deregulations that could be the starting point for the identification of effective biomarkers in future. Saliva samples collected from 6 PBC patients were analyzed using a liquid chromatography-tandem mass spectrometry technique, and the results were compared with those previously obtained in the PSC group. We identified 40 proteins as significantly deregulated in PSC patients compared to the PBC group. The Gene Ontology and pathway analyses highlighted that several proteins (e.g., small integral membrane protein 22, cofilin-1, macrophage-capping protein, plastin-2, and biliverdin reductase A) were linked to innate immune responses and actin cytoskeleton remodeling, which is a critical event in liver fibrosis and cancer progression. These findings provide new foundations for a deeper understanding of the pathophysiology of PSC and demonstrate that saliva is a suitable biological sample for obtaining proteomic fingerprints useful in the search for biomarkers capable of discriminating between the two cholestatic diseases.

Background And Aims: Primary sclerosing cholangitis (PSC) is a known risk factor for hepatobiliary malignancies. We conducted a systematic review and meta-analysis of published studies to determine the incidence and risk factors for hepatobiliary malignancies in people with PSC.
Methods: Pubmed and Embase databases were searched from inception to April 10, 2024 for cohort studies reporting data on the incidence of cholangiocarcinoma (CCA), hepatocellular carcinoma (HCC), or gallbladder cancer (GBC) in PSC.

Primary sclerosing cholangitis (PSC) is a risk factor for cholangiocarcinoma. When a child is diagnosed with both PSC and inflammatory bowel disease (IBD), evidence-based information on counseling families and risk management of developing cholangiocarcinoma is limited. In this case series (PubMed/collaborators), we included patients with PSC-IBD who developed cholangiocarcinoma and contacted authors to determine an event curve specifying the time between the second diagnosis (IBD or PSC) and a diagnosis of cholangiocarcinoma.

Introduction: Patients with a large vessel occlusion (LVO) stroke who are transferred to a comprehensive stroke center (CSC) for endovascular thrombectomy (EVT) often experience infarct growth. We aimed to investigate the clinical predictors of fast infarct growth and its effect on clinical outcomes.
Methods: We retrospectively collected EVT data of patients with LVO transferred to our center between March 14, 2019, and June 28, 2022.

Background And Aim: Prognosis in autoimmune hepatitis (AIH), primary biliary cholangitis (PBC), and primary sclerosing cholangitis (PSC) has historically been poor. This multicenter retrospective cohort study investigated the natural history and assessed the predictors of outcomes in patients with AIH, PBC, and PSC.
Methods: AIH, PBC, and PSC patients were identified from the state-wide Hepascore and Clinical Outcome cohort.
