ABSTRACT
Objective:
Analysis the relationship between antiribosomal antibodies with molecular weight 38 kD and/or 15/16.5 kD protein and SLE,then to discuss the positive standard of anti ribosomal antibodies and its prevalent rate in SLE patients.Methods:
262 sera from 115 SLE, 57 RA,20 SSc,39 MCTD and 31 other immune diseases were detected anti ENA antibodies by Western blot method.Results:
Respectively, use 38 kD and 15/16.5 kD protein bands appear simultaneously and 38 kD protein bands appear as anti ribosomal antibodies’ positive standard, the sensitivity and specificity of anti ribosomal antibodies to SLE were 17.4%,97.3% and 28.7%,96.6% respectively.The sensitivity had significant difference (P0 05).SLE patients were dramatically dominated in 14 anti ribosomal 38 kD antibody positive patients(71.4% vs. 28.6%,P0 05).Conclusion:
Anti ribosomal 38 kD antibody was closely associated with SLE but not with anti Sm antibody. Use 38 kD protein as the primary standard to verdict anti ribosomal antibody,not only can improve the positive rate of anti ribosomal antibody, but also do not depress its diagnostic specificity for SLE.So it’s worthy to spread this method.
