Predictive value of presepsin and acylcarnitines for severity and biliary drainage in acute cholangitis.

Background: Bacteremia, which is a major cause of mortality in patients with acute cholangitis, induces hyperactive immune response and mitochondrial dysfunction. Presepsin is responsible for pathogen recognition by innate immunity. Acylcarnitines are established mitochondrial biomarkers.

Optimal timing of biliary drainage based on the severity of acute cholangitis: A single-center retrospective cohort study.

Background: Biliary decompression is well known to greatly decrease the risks of mortality in acute cholangitis (AC). Although early biliary drainage is recommended by the treatment guidelines for AC, the best time for performing this procedure is yet to be established. Furthermore, since the clinical outcomes of patients with severe AC vary dramatically, screening for patients that could benefit the most from early drainage would be more beneficial than the drainage performed based on the severity grade criteria.

Presepsin as a biomarker for risk stratification for acute cholangitis in emergency department: A single-center study.

Background: Acute cholangitis is caused by bacterial infection and has high morbidity and mortality risk. The grade of cholangitis can guide clinical treatment from single antibiotic treatment to biliary drainage. With the introduction of white blood cell (WBC) count, C-reactive protein (CRP), and total bilirubin (T-Bil) into the diagnostic criteria and severity grading for acute cholangitis, the diagnosis rate and grading have significantly improved.
