[VIRTUAL] Serum bile acid species are associated with liver fibrosis and clinical disease progression in patients with primary sclerosing cholangitis (EASL-ILC-I 2020)
Levels of 15 BAs and the BA intermediate, 7α-hydroxy-4-cholesten-3-one (C4), were quantified by LC-MS/MS (Agilent 1290/Sciex, Metabolon) in fasting serum samples from patients with compensated large-duct PSC at baseline (BL) in a 96-week, phase 2 trial of simtuzumab (NCT01672879)... In patients with compensated PSC, total serum BAs, as well as conjugated primary BAs, are markers of liver fibrosis and predict clinical disease progression. These data support ongoing evaluation of therapies that reduce BA levels (e.g. FXR agonists) for the treatment of PSC.
