AARC score and urine NGAL predict terlipressin non-response and mortality in patients with acute-on-chronic liver failure.

Background And Aim: Acute-on-chronic liver failure (ACLF) patients with hepatorenal syndrome (HRS-AKI) have limited response to vasoconstrictors and worse outcomes, requiring biomarkers for early detection.

Methods: In a prospective cohort of ACLF patients (n = 240), urine NGAL was performed in patients with the clinical diagnosis of HRS-AKI, while in a subset of patients (n = 30), a complete panel of 17 urinary biomarkers was assessed for identifying terlipressin non-response (T-NR).

Results: ACLF patients with HRS-AKI, aged 45.
