[Connective tissue diseases and HEp-2 antinuclear antibodies].
Some characteristics of antinuclear antibodies that might be of use for diagnostic and/or prognostic purposed were studied using indirect immunofluorescence on HEp-2 cells in 55 cases of various types of connective tissue disease. For each nuclear (homogeneous, speckled, granular, dotted, pulverulent and centromeric) and nucleolar fluorescence pattern (homogeneous, conglutinated and dotted), the following parameters were observed; C3 fixing capacity, degree of antibody affinity and sensitivity to RNAse, DNAse and trypsin. The results were very interesting, especially in relation to the diagnosis of progressive systemic sclerosis and of the related subsets, but were insufficient for reliable, conclusive prognostic evaluation.
