The study of Anti-cyclic citrullinated peptide antibodies and rheumatoid factors with the disease activity of rheumatoid arthritis / 中华风湿病学杂志

ABSTRACT

Objective To compare the correlation between ACCP, IgA-RF, IgG-RF, IgM-RF and disease activity, bone erosion of rheumatoid arthritis. Method The correlation analysis between ACCP, IgA-RF, IgG-RF, IgM-RF and disease activity score (DAS), Ritchie′s articular index (RAI) were made SPSS software. ACCP, IgA-RF, IgG-RF, IgM-RF were compared between patients with erosive disease and with non-erosive disease. Results IgM-RF was associated with RAI, but ACCP, IgA-RF and IgG-RF were not associated with RAI. The above parameters were not associated with DAS by Spearman correlation analysis. The association between above parameters and bone erosion was not detected, however. Conclusion IgM-RF is associated with disease activity. ACCP and IgA-RF, IgG-RF are not associated with disease activity. No association is found between above parameters and bone erosion.
