ABSTRACT

Objective To explore the significance of antinucleosome and anti-dsDNA antibodies on the disease flare and organ damage in patients with systemic lupus erythematosus(SLE).Methods Sixty-nine SLE patients were divided into disease flare group,stable group,lupus nephritis group and non-lupus nephritis group.Serum levels of anti-nucleosome antibody and anti-dsDNA antibody were measured with enzyme linked immunosorbent assay(ELISA) and indirect immunofluorescence(IIF),respectively.Results The positive rates of serum anti-nucleosome and anti-dsDNA antibodies were 55.10% and 47.82% respectively and the rates were significantly higher in disease flare group than those in disease stable group(P
