Biomarkers of Chronic Uveitis in Juvenile Idiopathic Arthritis: Predictive Value of Antihistone Antibodies and Antinuclear Antibodies

Abstract

No association was found between E-ANA and uveitis, and most IF-ANA-positive sera were E-ANA-negative. E-ANA is not clinically relevant in this setting and should never be used to determine frequencies of eye examinations to detect new uveitis in JIA. AHA >/= 8 U/ml, IF-ANA titer >/= 320, and young age at onset of arthritis were significant predictors for development of chronic uveitis. The diagnostic value of AHA >/= 8 U/ml as a biomarker of chronic uveitis in JIA is very similar to IF-ANA >/= 80.
