Core Tip

Core tip: IgG4-associated autoimmune hepatitis (IgG4-AIH) is a new disease entity characterized by the accumulation of IgG4-expressing plasma cells in the liver. Recent studies diagnosed IgG4-AIH based on hepatic accumulation of IgG4+ cells alone or in combination with elevated serum concentrations of IgG4. Further studies are required to determine whether IgG4-AIH is a subtype of AIH or a hepatic manifestation of IgG4-related disease.
