PRIMARY BILIARY CHOLANGITIS

Primary biliary cholangitis (formerly primary biliary cirrhosis) is a chronic, progressive, autoimmune, cholestatic liver disease more common in middle-aged women. It is characterized by destruction of small to medium bile ducts leading to cholestasis and frequently, end-stage liver disease.
Diagnostic features are chronic biochemical cholestasis, presence of antimitochondrial antibodies and the characteristic liver biopsy findings.


 

Introduction

  • Primary biliary cholangitis (PBC) is an autoimmune disease of a chronic and progressive nature, characterized by destruction of small to medium bile ducts, leading to cholestasis and frequently, end-stage liver disease
    • Diagnostic features of PBC are the chronic biochemical cholestasis, presence of antimitochondrial antibodies (AMA) and the characteristic liver biopsy findings
  • Suggested to have environmental and/or genetic factors affecting its development
