[Monomeric igM in acute and chronic liver diseases (author's transl)].

Monomeric IgM could be found rather frequently in acute hepatitis and chronic aggressive hepatitis and occasionally also in chronic persistent hepatitis. Earlier it was reported in lympho-proliferative-, autoimmune diseases, some infectious diseases and in cirrhosis of the liver. The occurence of monomeric IgM in chronic aggressive hepatitis correlates with the detection of several autoantibodies (ANA, SMA, RF). The 7S-IgM-test may be used as an easily measurable additional criterium for diagnosis and course of chronic liver diseases.
