Patients With Primary Biliary Cholangitis(PBC)

Overview

Primary Biliary Cholangitis (PBC) is a chronic autoimmune cholestatic liver disease characterized by the progressive destruction of small intrahepatic bile ducts, leading to chronic cholestasis, hepatic fibrosis, and, in advanced stages, cirrhosis. Recent advances in the understanding of PBC pathophysiology have highlighted the central role of immune, inflammatory, and metabolic alterations in disease onset and progression.

The study will enroll patients with Primary Biliary Cholangitis (PBC) for whom treatment with PPAR agonists has been prescribed in routine clinical practice, either as first-line or second-line therapy according to current clinical indications. The study procedures include: * Collection of demographic, clinical, laboratory, and treatment-related data. All information will be retrospectively and prospectively collected from patients' medical records and routinely available clinical documentation. * Collection of additional peripheral blood samples (10 mL) at baseline (T0) and after 3 months of therapy (T3). Blood sampling will be performed concurrently with routine blood draws already scheduled as part of standard clinical monitoring and follow-up of PBC patients, without requiring additional clinical visits or invasive procedures beyond standard care.
