[Clinical and serological aspects of the pseudo-LE syndrome (author's transl)].

Fifteen women with pseudo-LE syndrome were studied. The dissease is characterized by recurrent attacks of fever, myalgia, arthralgia, visceral manifestations (pericarditis, myocarditis, pleurisy, pleural effusion and lung involvement). A prominent feature was an abnormal liver function with elevated GOT and GPT levels in serum, and impaired bromsuophalein elimination. The incidence of varicosities and thrombophlebitis was markedly increased. There was a correlation between complement-fixing antimitochondrial antibody (AMA) titres and the degree of activity of the disease. A reverse correlation was observed between antimitochondrial antibody titres and the absolute lymphocyte count in peripheral blood. In all instances the antimitochondrial antibodies were of polyclonal origin, belonging mainly to immunoglobulin class IgG and, in a few patients, IgM, IgA, or IgD. AMA titres, lymphocyte counts in peripheral blood, sedimentation rate, serum iron level and alpha1- and alpha2-globulins proved to be valuable in following the course of the disease. Other values (C-reactive protein, alpha1-acid glycoprotein, immunoglobulin and beta1c-globulin in serum) were not helpful.
