Patients with autoimmune urticaria show a higher rate of seropositivity for other autoantibodies and often have a history of autoimmune conditions. They also tend to have more severe symptoms and to have a poor response to conventional antihistamine treatment. Autoimmune hepatitis is a chronic inflammatory disorder in which progressive liver injury is thought to be the result of a T-cell-mediated immunologic attack against liver cells in genetically predisposed individuals. While the association between autoimmune urticaria and other autoimmune disorders such as thyroid disease is well known, there has been no reported case of autoimmune urticaria concomitant with autoimmune hepatitis. We report a case of autoimmune urticaria concurrent with autoimmune hepatitis, which was successfully treated with cyclosporine.
