Liver Failure in Autoimmune Hepatitis Overlap Syndrome With Primary Biliary Cholangitis: A Case Report

Area of Science:

• Hepatology
• Immunology
• Internal Medicine

Background:

• Autoimmune hepatitis (AIH) is a chronic liver disease characterized by autoantibodies and inflammation, often co-occurring with other autoimmune conditions.
• Primary biliary cholangitis (PBC) is another autoimmune liver disease that can overlap with AIH, complicating diagnosis and treatment.
• Limited research and lack of standardized protocols hinder effective management of AIH and its overlap syndromes.

Observation:

• A 54-year-old female presented with acute hepatitis rapidly progressing to liver failure.
• Differential diagnoses were excluded, and a presumptive diagnosis of AIH was made.
• Corticosteroid therapy was initiated for suspected AIH.

Findings:

• Liver biopsy confirmed an overlap syndrome of AIH and PBC.
• The patient's presentation underscores the potential severity of AIH and overlap syndromes.
• Successful corticosteroid treatment initiated based on clinical suspicion and biopsy confirmation.

Implications:

• This case highlights the diagnostic challenges and critical need for timely intervention in AIH-PBC overlap syndromes.
• Further research into standardized treatment protocols for AIH and its variants is crucial.
• Early diagnosis and immunosuppressive therapy are vital for preventing advanced liver disease, including cirrhosis and failure.
