[Membrano proliferative glomerulonephritis (author's transl)].

128 cases of Membrano proliferative glomerulonephritis have been divided in two groups, the first one (84 cases), with subendothelial deposits, the second one (44 cases) "with dense intramembranous deposits". Streptococcal infections more frequently precede the membranoproliferative glomerulonephritis with dense intramembranous deposits (20% and 11%). In this group there is a rapid onset and macroematuria is more frequent (36% and 18%). Nephrotic syndrome has the same frequency in the two groups (more than 80%). Because of the more frequent association "dense deposits" and crescents this group show a more frequent evolution toward renal failure (43% and 35%).
