Overlap syndromes in AIH are often suggested by the existence of markedly elevated alkaline phosphatase or positive AMA. There are no standardized criteria for the diagnosis of AIH-PBC overlap syndrome. The occurrence of this eye disorder provides additional support for an autoimmune pathogenesis for CAH. ALT = alanine aminotransferase; AMA = antimitochondrial antibodies; GGT = gamma-glutamyl transferase; IgG = immunoglobulin G; ASMA = antismooth-muscle antibody. Autoimmune hepatitis (AIH) is a female predominant condition characterized by immune-mediated destruction of liver parenchyma and presence of peripheral autoantibodies (1,2).Waldenström first described this disease in a group of young females with hypergammaglobulinemia over 60 years ago ().Despite forward progress in diagnosis and therapeutic … Autoimmune chronic active hepatitis associated with the presence of antiphospholipid antibodies.

Clinicians should be alert to … color: #00a5db; These antibodies are not readily available in many institutions, hence the diagnosis of AIH when typical antibodies are negative will most often rely on histologic features. Thus we conclude that anti-human asialoglycoprotein receptor antibodies can serve as diagnostic markers for inflammatory active cases of autoimmune chronic active hepatitis. The most common immunosuppression regimen used in patients after liver transplant is the combination of calcineurin inhibitor, usually tacrolimus, with prednisone. According to the European Association for the Study of the Liver, UDCA may be tried first in these patients, with prednisone and azathioprine added later if there is an inadequate response after 3 months.
