Correlation of inflammatory RA disease activity with laboratory parameters.
Fifty-one patients with rheumatoid arthritis were examined at 6-month intervals during a 2-3-year investigation period. Correlations of an inflammatory activity index calculated from nine criteria with several laboratory parameters were computed. ESR correlated most closely, followed by the IgM concentration of circulating immune complexes, hemoglobin, C3A, and fibrinogen.
