Autoimmune liver disease is the second commonest cause of chronic liver disease in teenagers. There are several forms including autoimmune hepatitis, autoimmune sclerosing cholangitis, primary sclerosing cholangitis and various overlap syndromes, classified on the basis of different serum antibody profiles, histological features and appearances on cholangiography. Treatment with immunosupressants is usually effective, but often required medium to long-term, raising concerns about side effects and adherence to therapy. For a minority of children presenting in acute liver failure or with difficult-to-treat disease liver transplantation is a possible option, although risk of recurrence in the grafted liver remains lifelong.
