A most unusual case of chronic membranoproliferative glomerulonephritis with nodule formation is reported in an elderly man in whom it was possible to document many episodes of acute oilguric and hemorrhagic glomerulonephritis and a syndrome resembling acute rheumatic fever. Severe renal failure necessitating peritoneal dialysis occurred on three occasions. Renal function returned to near preexacerbation levels in each episode. Although there was strong clinical evidence for streptococcal hypersensitivity, convincing laboratory documentation was lacking. The histologic and immunopathologic findings changed comparatively little during the several exacerbations. Impairment in fibrinolytic and coagulation activities by circulating macromolecular complexes is postulated for the induction and perpetuation of the glomerular injury.
