[Lupus-erythematosus-like syndromes].

Report on 3 patients with lupus-erythematosus-like syndromes, in which antinuclear antibodies in high titres and peripheral (or homogeneous) pattern--the characteristic leading immunologic phenomenon of SLE--could not be observed. The second patient suffered from the so-called pseudo-LE-syndrome described by Maas and Schubothe and characterized by antimitochondrial antibodies in high titres. The disease of the 3rd patient was explained as drug-induced LE-syndrome by Ovosiston. The variety of the antigens and antibodies directed against them, the improved diagnostics as well as the increased consumption of drugs were taken as reasons for the growing frequency of such LE-like syndromes. The coexistences, overlappings and transitional forms among the special autoimmune diseases render the diagnostics more difficult and explain the great variety of pictures of the SLE.
