De novo autoimmune hepatitis after liver transplantation / 中华肝脏病杂志

ABSTRACT

Patients who transplanted for non-autoimmune indication may developed de novo autoimmune hepatitis after liver transplantation. It happens about 1.7%-6.6% in liver transplanted population. Most patients with de novo AIH had transplanted for HCV infection, biliary atresia and Cholestatic liver disease. The interval between transplantation and de novo AIH onset is from 3 month to 16 years, mostly more than 1 year. The disease can be seen at any age. More female patients are present in children, while there is no significant difference between male and female in adults. Clinical manifestations of de novo AIH are similar to those of AIH, namely characterized by elevated transaminase with or without bilirubin, as well as elevated serum gammaglobulin (IgG) and positive autoantibodies, while the histological features of an infiltrate rich in plasma cells with interface hepatitis and necro-inflammation and fibrosis. Treatment with corticosteroids and Azathioprine brings good outcomes, but it tends to fluctuate.
