title: Immune complexes in children with different forms of glomerulonephritis.
abstract: The occurrence of circulating immune complexes was tested in 43 children with different forms of glomerulonephritis (GN). The presence of immune complexes was demonstrated in sera of 6 out of 10 patients with GN of hepatitis B etiology, in 6 out of 11 patients with GN of bacterial etiology, and in 3 out of 10 patients with GN of unknown etiology. Immune complexes were not found in sera of 3 patients with Schönlein-Henoch disease, in 6 patients with lipoid nephrosis, and in 3 patients with GN and hepatitis B as a coexisting infection. In a patient with membrane-capillary GN which appeared after infection with hepatitis B virus we demonstrated immune complexes of M.W. 4.0 X 10(6) and 7.5 X 10(5).
