Uveitis and anti nuclear antibody positivity in children with juvenile idiopathic arthritis.
This study was conducted to determine the frequency of antinuclear antibodies (ANA) positivity and uveitis in our newly diagnosed juvenile idiopathic arthritis (JIA) patients classified according to International League Against Rheumatology (ILAR) classification criteria. Ninety-two girls and 106 boys, totally 198 children were enrolled in the study. of them 36 (18.2 percent) were found to be ANA positive. Chronic anterior uveitis was detected in 20 (10.1 percent) patients. ANA positivity was determined in 4 of the systemic JIA patients, in whom no uveitis had been detected. Twenty-five of 37 patients with oligoarticular JIA were ANA positive, in 10 of them uveitis was also diagnosed. ANA were positive in 3 of 34 patients with RF positive polyarticulat JIA, only one patient had positive ANA, and another one had uveitis. Nine patients were extended JIA and in none of them, ANA positivity or uveitis were present. Of 43 patients classified as enthesitis related arthritis (ERA), uveitis was diagnosed in 6 and there was no evidence of ANA positivity, but one had uveitis. We conclude that the incidence of ANA positivity and uveitis is low in Turkish children with JIA.
