Advancing the management of primary biliary cholangitis: From pathogenesis to emerging therapies.

Primary biliary cholangitis is a chronic cholestatic autoimmune liver disease that progressively damages the bile ducts, leading to cholestasis and, in advanced stages, cirrhosis. While it primarily affects middle-aged women, recent data indicate a rising incidence in men. The interplay between genetic susceptibility, environmental exposures, and gut microbiome alterations is thought to drive disease onset. Diagnosis relies on persistent cholestatic enzyme elevation, disease-specific autoantibodies, and, in select cases, liver biopsy. Ursodeoxycholic acid remains the cornerstone of treatment, but many patients show an incomplete response. The recent withdrawal of obeticholic acid from the market, due to insufficient evidence of long-term benefit, has highlighted the urgent need for effective second-line therapies. Agonists of peroxisome proliferator- activated receptors, such as elafibranor and seladelpar, have demonstrated promising biochemical improvements and may reshape the therapeutic landscape. Future research is focused on refining risk assessment, optimizing treatment combinations, and addressing symptoms such as fatigue and pruritus to enhance patient well-being. A shift toward early intervention and personalized treatment strategies may further improve long-term outcomes in primary biliary cholangitis.
