[Quantitative alterations of the immunoglobuline classes and the presence of autoantibodies in liver diseases (author's transl)].

The AA., after the literature revision concerning the autoantibodies in the autoimmune diseases, have examined the cases of acute and chronic hepatitis happened in the period 1972-1976. After a short observation of used methodologies the AA. have connected the presence of autoantibodies (FN, SM, AM) with the rate of immunoglobulins in single groups of liver diseases, divided in acute hepatitis, chronic persistent hepatitis, chronic active hepatitis, liver cirrhosis (cryptogenetic and alcoholic). The results are that while the immunoglobulins fractions increase, although in different manner, in every pattern of liver disease studied, instead, there are no typical changes of single immunoglobulins rate in the groups with autoantibodies. Statistically it is not possible to assert that single antibodies belong to immunoglobulins determinate class. Finally it had been impossible to demonstrate sex and age influence on the immunoglobulins increase in the groups of liver disease with autoantibodies.
