Abstract:
Objective To determine the diagnostic value of antifilaggrin antibodies(AFA) in rheumatoid arthritis(RA) and to compare the correlation among AFA,anti-perinuclear factor(APF) and anti-keratin antibodies(AKA). Methods Filaggrin was extracted from human epidermis and then partially purified. AFA in 103 cases of RA and 140 cases of controls were detected by western blot. APF and AKA were detected using indirect immunofluorescence. Results AFA test resulted in diagnosis of 35.9% of 103 RA samples, with a specificity of 93.7%. The result was significantly higher than the controls (P
