Circulating immune complexes (CIC), mainly IgA-CIC have been frequently detected in IgA nephropathy and recently increased levels of C3 fragments which indicate C3 activation have been reported. However, little is known about the relationship between CIC and complement activation. We determined CIC by the solid-phase anti-C3 Facb enzyme immunoassay in 37 children with IgA nephropathy to investigate the relationship between CIC and clinical and/or histological findings, and also determined C3 fragments whether CIC correlate with complement activation. IgA-CIC were detected in 78% (27/37) with a mean level of 11.9 +/- 3.9 micrograms/ml, which was significantly higher than other glomerular diseases (P less than 0.05). IgA-CIC levels were also found significantly higher in 27 cases with proteinuria than in 10 cases without proteinuria (P less than 0.05). IgG-CIC were detected in 67% (12/18) with a mean level of 4.1 +/- 2.6 micrograms/ml, which was not significantly different from other glomerular diseases. No striking correlation was noted to exist between CIC levels at renal biopsy and the histological severity, because CIC are often present intermittently. C3d was quantitated by the rocket immunoelectrophoresis and C3 by the single radial immunodiffusion to determine the C3d/C3 ratio. The mean value of C3d/C3 was 0.63 +/- 0.19 which was significantly higher than a corresponding value for 15 healthy controls of 0.27 +/- 0.06 (P less than 0.05). Levels of IgA-CIC were found to have a significant positive correlation between C3d/C3 determined simultaneously in 33 cases (r = 0.43, P less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)
