Autoimmune Liver Diseases (AILD)

• Autoimmune Hepatitis (AIH)

  Autoimmune Hepatitis (AIH) is a chronic liver disease characterised by increased serum transaminases and immunoglobulin G, circulating autoantibodies and infiltration of immune cells on liver histology. Its pathogenesis is largely unknown, but an autoimmune reaction directed against hepatocytes is assumed.…
