Abstract:
Objective To assess the diagnostic value of anti-cyclic citrullinated peptide antibody(an- ti-CCP),rheumatoid factor,anti-perinuclear factor(APF)and anti-keratin antibody(AKA)for juvenile rheumatoid arthritis(JRA)and compare it with rheumatoid arthritis(RA).Methods Anti-CCP was determined by ELISA in 54 serum samples of JRA patients,31 from patients with other rheumatic diseases and 116 RA patients.RF was determined in the same samples by latex agglutination test.APF and AKA were determined by indirect immunofluorescent assay.Results The sensitivity of anti-CCP,RF,APF and AKA was 61.1%, 57.4%,37.0% and 18.5% and their specificity was 96.8%,93.6%,96.8% and 100%,respectively for the diag- nosis of JRA.The sensitivity of anti-CCP resembleed that of RF,Anti-CCP was more sensitivity than APF and AKA in JRA.The sensitivity of anti-CCP,RF,APF and AKA was 82.3%,78.3%,48.7% and 25.4% and their specificity was 95.7%,73.7%,91.6%,94.0% respectively,for the diagnosis of RA.Anti-CCP,RF,APF and AKA were less sensitive in JRA than in RA.There was no statistical significance in specificity of these anti- bodies for the diagnosis of JRA and RA.Conclusion The detection of anti-CCP,RF,APF and AKA are use- ful for the diagnosis of JRA,but are less sensitive than in adults RA.
