SLA autoantibodies are associated with autoimmune hepatitis (AIH), type 2. AIH patients are generally divided into 2 groups based on the presence of specific autoantibodies. AIH type 1 (also referred to as classic, active chronic, lupoid, plasma cell, or autoimmune chronic active hepatitis) is the more common type of AIH. AIH-1 is characterized by antinuclear, anti-smooth muscle (directed against both anti-actin and non-actin components), and perinuclear anti-neutrophil cytoplasmic antibodies. AIH type 2 is characterized by antibodies directed primarily against soluble liver antigen (SLA) and anti-liver cytosol antigen (LC-1), whereas AIH-1 patients are negative for SLA and LC1 antibodies. Although only about 12-30% of AIH patients have SLA antibodies, the presence of SLA antibodies has almost 100% specificity for AIH.
