[Variant syndromes in autoimmune hepatic diseases].
Some autoimmune hepatic diseases patterns can be of difficult classification, sometimes as overlap of autoimmune hepatitis, primary biliary cirrhosis, primary sclerosing cholangitis and chronic viral hepatitis. The recognition of these forms is not so easy, but it is necessary for an effective therapeutic approach. At present, the specificity in these cases of the score system done and revised by the International Autoimmune Hepatitis Group is being discussed. Patients showing such diseases have different modalities of presentation of their hepatic disease and different courses. The role of histology appears to be important, but often the overlap of more manifestations is not helpful to a correct diagnostic definition. The variant syndromes could be classified as intermediate patterns of cholestatic forms and of autoimmune hepatic diseases or cholestatic forms of autoimmune hepatitis or hepatitic forms of cholestatic syndromes.
