Background & Aims: Autoimmune hepatitis (AIH) is characterized by the presence of circulating autoantibodies, hypergammaglobulinemia, necroinflammatory histology, and a response to immunosuppressive drugs. The goal of this retrospective study was to determine whether the presence of antinuclear antibodies (ANAs) or anti-smooth muscle antibodies (ASMAs) in patients with AIH correlated with clinical presentation, histologic findings, or response to immunosuppressive therapy.
Methods: Fifty-two patients diagnosed with AIH, on the basis of the revised scoring system of International Autoimmune Hepatitis group, were reviewed.
