Autoimmune Hepatitis and PSC Connection.

This article describes the connection between autoimmune hepatitis (AIH) and primary sclerosing cholangitis (PSC). The two conditions have chronicity, liver inflammation, and a positive autoimmune serology in common; they differ in terms of gender distribution and bile duct damage. There is evidence suggesting that AIH and PSC are immune-mediated diseases. PSC and AIH could lie within the spectrum of the same disease process. Future studies should determine how frequently AIH evolves to PSC.
