Antinuclear Ab, HEp-2 substrate

J M Corres González, C Rodríguez Hernández, A C Zea Mendoza, J Sequí Navarro, I Sanchidrián Fernández
OBJECTIVES: To compare indirect immunofluorescence (IIF) with immunoblotting (IB) in the detection of antiribosomal antibodies (anti-P Ab) in patients with systemic lupus erythematosus (SLE) and to investigate the possible association between anti-P Ab with serological and clinical findings in SLE, particularly with neurological manifestations. METHODS: Serum specimens from 44 SLE patients and 10 healthy subjects were investigated for anti-P Ab using IB and IIF in rat triple substrate and HEp-2 cells...

Fifty-seven sera from 53 patients were assayed simultaneously on KB and HEp-2 cells and compared with regard to pattern and titer. Additionally, KB cell fluorescent antinuclear antibody (FANA) titer and pattern in 310 sera from 194 patients were compared with regard to the presence of antinative DNA antibodies (anti-nDNA ab) as determined by the Crithidia luciliae assay. Sixty-five percent (37/57) of the sera had the same titer on both KB and HEp-2 cells; the remainder had higher titers using KB cells. Regression analysis yielded a highly significant, unbiased correlation between the substrates...

We detected anticellular antibodies (Ab) in 867 sera from patients with inflammatory rheumatic disorders by indirect immunofluorescence technique on HEp-2 cells and searched for clinically relevance of the rare fluorescence staining pattern (n = 133). We could find associations of 1. spekled nuclear pattern and Ab to U1-nRNP and La, 2. nucleolar pattern and scleroderma, 3. peripheral nuclear membrane pattern, Ab to dsDNA and SLE, 4. centromere staining and CRST syndrome, 5. intermediär filament pattern and permanent cellular destructions in erosive arthritis, 6...
