C3 nephritic factor and C4 nephritic factor in the serum of two patients with hypocomplementaemic membranoproliferative glomerulonephritis.

Abstract

Both C3 nephritic factor (C3NeF) and C4 nephritic factor (C4NeF) were found in the serum of two patients with hypocomplementaemic membranoproliferative glomerulonephritis type 1 (H-MPGN type 1). Both stabilizing activities were associated with the IgG fraction. The serum levels of C3 and C5 were quite low, whereas the levels of early components and control proteins were in the normal range.
