A form of autoimmune hepatitis characterized by clinical presentation as cryptogenic hepatitis, interface hepatitis on histological examination, elevated serum aminotransferase levels, hypergammaglobulinemia/elevated immunoglobulin G, and presence of circulating autoantibodies, specifically antinuclear antibodies (ANA), anti-smooth muscle antibodies (anti-SMA), and/or anti-soluble liver antigen/liver pancreas antigen antibodies (anti-SLA/LP). The disease predominantly develops at a post-pubertal age and most commonly takes a chronic course, although acute or acute severe presentation may also be observed. Typical concurrent autoimmune diseases are autoimmune thyroiditis and rheumatic diseases.
