| A rare hepatic disease characterized by the overlap of primary biliary cholangitis and/or primary sclerosing cholangitis with autoimmune hepatitis, defined by the presence of at least two of the three recognized biochemical, serological and histological criteria of each disease. The onset of the overlapping diseases can be simultaneous or sequential with a variable interval of up to several years. Age of onset, gender predisposition and clinical phenotype vary between each of the diseases. The clinical presentation ranges from asymptomatic disease or unspecific symptoms such as fatigue, arthralgia and pruritus to established cirrhosis and decompensation or also acute fulminant hepatitis and liver failure. Association with extrahepatic autoimmune diseases is common. |
