Abstract

Presence and titer of antinuclear antibodies (ANA) were determined in 217 juvenile rheumatoid arthritis (JRA) patients, by indirect immunofluorescence using HEp‐2 cells as substrate. Positive ANA titers (⩾1:40) were present in 131 (60%) of the JRA patients. All 3 JRA onset types demonstrated increased percentages of ANA positivity compared with healthy children. Sixty‐seven percent of the patients in the polyarticular onset group had positive titers; titers were positive in 62% of the pauciarticular onset group and in 32% of the systemic onset group. ANA were also found in 45% of control patients with other connective tissue diseases. In JRA patients, the speckled pattern occurred most commonly (72%). Fourteen patients (8 with pauciarticular onset and 6 with polyarticular onset) had iridocyclitis; all of them had high titers (⩾1:80) of ANA. The use of HEp‐2 cells provided a sensitive substrate for detecting ANA in JRA. It proved to be of value in differentiating JRA patients from healthy controls, but not from patients with other connective tissue diseases.
