Autoimmune hepatitis is a chronic, inflammatory disease of the liver that is characterized by circulating autoantibodies and elevated serum. UpToDate, electronic clinical resource tool for physicians and patients that provides information on Adult Primary Care and Internal Medicine, Allergy and. AIH is a complex diagnosis partly because there is no anatomic criterion (i.e. ‘ gold’) standard. AIH scoring neatly solves this problem by defining the diagnosis.

Post-liver transplantation de novo hepatitis with overlap features. Clin Exp Gastroenterol Review. Apart from the virtuous effect on viral clearance, the recognition of viral antigens at the same time may lead to the expression of self-antigens, which can result in an alloimmune reaction sustained by memory T-cells[ 24265 ].
Expert opinion has been summarized by the International Autoimmune Hepatitis Group, which has published criteria which utilize clinical, laboratory, and histological data that can be used to help determine if a patient has autoimmune hepatitis.

About the Creator Dr. Rapid withdrawal of immunosuppression is associated with high risk of disease relapse in many patients. Other autoimmune disease s in patient or 1st degree relatives 2. Still, the overall features of de novo autoimmune hepatitis appear not to be attributable to a univocal patho-physiological pathway because they can develop in the patients who have undergone liver transplantation due to different etiologies.
The mechanisms that are thought to contribute to the genesis of liver graft autoimmunity are at least in part induced by immunosuppressive agents[ 8 ]. Effects of immunosuppression and organ transplantation on the natural history and immunopathogenesis of hepatitis C virus infection.
