AI Article Synopsis

  • The study focuses on early-stage primary biliary cholangitis (PBC) with a rare condition known as ductopenia, which involves significant bile duct loss without major liver damage.
  • Researchers analyzed data from 141 PBC patients over 4.5 years, finding that those with ductopenia had notably higher levels of liver enzymes and cholesterol but a poorer response to standard treatments compared to those without ductopenia.
  • High baseline cholesterol levels were identified as a key predictor for ductopenia in early-stage PBC patients, indicating a potential risk factor for adverse health outcomes.

Article Abstract

Primary biliary cholangitis (PBC) with early cholestasis and extensive bile duct loss but no significant fibrosis or cirrhosis is rare and underrecognized. We aimed to clarify the clinicopathology features and prognosis of these variants of patients with early-stage PBC with ductopenia. From January 2009 to January 2023, we retrospectively collected the laboratory and pathologic data of patients with early-stage PBC and recorded their liver-related events with a median follow-up of 4.5 years. Finally, a total of 141 patients with PBC in the early stage were included and divided into 2 groups: one with ductopenia (n = 36) and the other without ductopenia (n = 105). The median age of the participants was 50 years, with 90.8% being female. The ductopenia group exhibited significantly elevated alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, gamma-glutamyl transpeptidase, total bilirubin, total bile acid, and total cholesterol (CHOL). Conversely, they showed a reduced biochemical response to ursodeoxycholic acid according to the Paris II, Barcelona, and Rotterdam criteria. A relatively poorer prognosis was observed in patients with early-stage PBC with ductopenia but with no statistical difference (11.8% vs 4.9%, P = 0.352). Baseline total CHOL levels were identified as an independent factor for the presence of ductopenia in early-stage PBC (odds ratio = 1.771, 95% CI: 1.264-2.479, P = 0.001). In conclusion, ductopenia was a significant risk factor for worse biochemical profiles and poor treatment response in patients with early-stage PBC. High levels of total CHOL at baseline are associated with the presence of ductopenia in early-stage PBC.
