Relation of clinical activity of rheumatoid arthritis to immune complexes, complement components and anti-immunoglobulins

Abstract

Circulating immune complexes by fluid phase Clq binding assay, complement components and anti-immunoglobulin levels were studied in sera of 35 patients with rheumatoid arthritis (RA). In 23 of the 35 sera (65.7%), circulating immune complexes were positive, and the mean±SD of Clq binding activity (ClqBA), 44.5±19.4%, was significantly high compared to that… (More)
