  • The Clinical Value of Anti-Ro52 and Anti-Ro60

    ObjectiveTo study the diagnosis value of anti-SSa (including anti-Ro52 and anti-Ro60). MethodsAntibodies of ENA (including Sm, Ro52, Ro60, SSb, RNP, Scl-70, Jo-1 and Rib-P) from 23145 patients with positive antinuclear antibody (ANA) were retrospected from January 2009 to December 2013. The relationship between anti-Ro52, anti-Ro60 and other test results and the diagnosis or symptomatic information of patients was also analyzed. ResultsThe anti-Ro60 positive rate was 35.19% (8 145/23 145), and the anti-Ro52 was 13.16% (3 046/23 145) in 23145 ANA positive cases (P<0.05). The positive percentage of anti-Ro60 was higher in anti-SSb, anti-RNP, anti-Sm and anti-Rib-P positive cases than anti-Ro52 (P<0.05); the results of anti-Ro52 negative and anti-Ro60 positive (Ro52-Ro60+) had a higher percentage in autoimmune diseases, non-autoimmune disease and symptoms groups than anti-Ro52 positive and anti-Ro60 negative (Ro52+Ro60-) results (P<0.05). ConclusionThe anti-Ro60 has higher positive rate than anti-Ro52, and the sensitivity and prediction value of autoimmune diseases of anti-Ro60 are better than anti-Ro52. But both anti-Ro60 and anti-Ro52 have poor specificity for disease diagnosis.
