Area of Science:

  • Hepatology
  • Immunology
  • Gastroenterology

Background:

  • Primary biliary cirrhosis (PBC) and autoimmune hepatitis (AIH) are distinct chronic liver diseases.
  • Overlap syndromes present with mixed features of both PBC and AIH, posing diagnostic and therapeutic challenges.

Observation:

  • Two female patients, aged 54 and 58, presented with clinical and biochemical evidence of cholestasis.
  • One patient had co-existing autoimmune phenomena, including rheumatoid arthritis and Sjögren syndrome.
  • Liver biopsies revealed cirrhosis with significant bile duct lesions.

Findings:

  • Both patients exhibited laboratory values indicative of cholestasis.
  • Histopathology confirmed liver cirrhosis with specific bile duct damage.
  • Treatment with prednisolone led to rapid normalization of liver function tests.

Implications:

  • These cases underscore the existence and recognition of overlap syndromes, also termed autoimmune cholangitis.
  • Prompt diagnosis and treatment with corticosteroids can effectively manage these mixed autoimmune liver conditions.
  • Further research into the pathogenesis and optimal management of PBC/AIH overlap is warranted.
