The diagnosis of autoimmune hepatitis (AIH) is based on a combination of clinical, laboratory and histological findings in patients with unexplained acute or chronic hepatitis [1–3]. The disease is considered rare but recent population-based studies from England and New Zealand have shown that AIH incidence is on the rise [4,5]. As in most autoimmune diseases, AIH is characterized by female predominance while every subject can be affected irrespective of age, gender, and ethnicity [6,7]. Differential diagnosis includes viral, toxic, genetic, and metabolic liver diseases [1–3,6].
