Abstract:
Objective To evaluate the diagnostic value of anti-nucleosome antibody for juvenile systemic lupus erythematosus (JSLE).Methods Fifty-four patients with JSLE,28 patients with non-JSLE and 26 healthy children were chosen in this study.antinuclear antibody(ANA),anti-nucleosome antibody (AnuA),anti-dsDNA antibody,anti-histone antibody (AHA) and anti-Sm antibody were detected by ELISA or western-blot method.The relevant clinical data were collected and analyzed.Results For diagnosis of JSLE,the sensitivity and specificity of AnuA was 77.78％ and 96.30％.The sensitivity of AnuA combined with ANA,anti-dsDNA and antiSm was higher than that of single detection.AnuA usually associated with fever,oral/nasal pharyngeal ulcer,lung damage,lymphocyte absolute value,urine protein and C3 level.Conclusion AnuA can be used as a serum marker for JSLE diagnosis.The detection of AnuA combined with anti-dsDNA and anti-Sm should be more helpful for diagnosis of JSLE.
