Background: Primary sclerosing cholangitis (PSC) is a rare chronic inflammatory liver disease characterized by biliary strictures and cholestasis. Due to the lack of effective serological indicators for diagnosis and prognosis, in the present study, we examined the potentiality of the saliva proteome to comprehensively screen for novel biomarkers.
Methods: Saliva samples of PSC patients and healthy controls were processed and subsequently analyzed using a liquid chromatography-tandem mass spectrometry technique. A bioinformatic approach was applied to detect the differentially expressed proteins, their related biological functions and pathways, and the correlation with the clinical evidence in order to identify a possible marker for the PSC group.
Results: We identified 25 differentially expressed proteins in PSC patients when compared to the healthy control group. Among them, eight proteins exhibited area under the curve values up to 0.800, suggesting these saliva proteins as good discriminators between the two groups. Multiple positive correlations were also identified between the dysregulated salivary proteins and increased serum alkaline phosphatase levels and the presence of ulcerative colitis. Pathway analysis revealed significant enrichments in the immune system, neutrophil degranulation, and in the interleukine-17 signaling pathway.
Conclusion: We demonstrated the potentiality of saliva as a useful biofluid to obtain a fingerprint of the pathology, suggesting disulfide-isomerase A3 and peroxiredoxin-5 as the better discriminating proteins in PSC patients. Hence, analysis of saliva proteins could become, in future, a useful tool in the screening of patients with suspected PSC.

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.

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.
