Abstract:
Objective To investigate the effects of anti-cell membrane associated DNA (mDNA) antibodies in the diagnosis of systemic lupus erythematosus (SLE) lacking of specific autoantibodies including anti Sm,anti ds-DNA,and anti-nucleosome antibodies.Methods Indirect immunofluorescence assay was used to measure anti-mDNA antibodies in serum of 145 SLE patients,and indirect immunofluorescence,Western-blot and ELISA were used to detect the anti-dsDNA ,anti-Sm and anti- nueleosome antibodies respectively to analysis the value of anti-mDNA antibodies on the specific autoantibodies negative patients with SLE.Results The sensitivity for anti-mDNA antibodies (69.7%) in SLE was significantly higher than anti-Sm (19.7%),anti-dsDNA ( 31.9% ) and anti-nucleosome (45.8% ).The incidences of anti-mDNA antibodies in SLE lacking of anti-dsDNA,Sm and anti-nueleosome antibodies (AnuA) were 64.3% ,70.2% and 60.3% respectively.Conclusion Anti-mDNA antibodies are serologic marker of SLE and important in diagnosis of SLE lacking of anti-dsDNA,Sm and nucleosome antibodies.
