Answer

Epidemiologic data are limited. Among white adults, the prevalence is estimated to be 0.1-1.2 cases per 100,000 individuals. The frequency of autoimmune hepatitis among patients with chronic liver disease ranges from 11%-23%. The disease accounts for about 6% of liver transplantations in the United States. Autoimmune hepatitis type 2 (AIH-2) and AIH-3 are observed infrequently in the United States, although AIH-2 is well characterized in Europe.
