[The antinuclear antibody spectrum in circumscribed forms of XXXX ].

@entity1 @entity6016 @entity27301 @entity2631 @entity1413 @entity785
Sera from 56 @entity1 with @entity2631 ( @entity2631 ) were tested for the presence of antinuclear antibodies (ANA) by indirect immunofluorescence on HEp-2-cells. 16 @entity1 (28.6%) had ANA, mostly in low titers of 1: 40 and with uncharacteristic fluorescence patterns. Nucleolar antibodies as in progressive @entity785 were seen in a few cases only. Two female patients demonstrated antibodies with a centromere-like pattern. ANA were most frequently found in @entity1 with @entity27301 idiopathica progressiva (60%) and in linear @entity2631 (44%). Rheumatoid factor was present in 62% of @entity1 with linear @entity2631 ; it was less frequent in other forms of @entity2631 . Antibodies against double-stranded DNA were found only in one female @entity1 , but three @entity1 with systemic involvement had antibodies to single-stranded DNA. Antibodies to soluble nuclear Scl-70, Ul-RNP and @entity6016 antigens or to the cytoplasmatic Ro(SSA)-antigen, respectively, were not detected in the @entity1 with @entity2631 . These results demonstrate that humoral autoimmune phenomena may occur in @entity2631 , mainly in @entity1 with linear @entity2631 . These phenomena, however, are less frequent and specific than in progressive @entity785 or in other @entity1413 .
