title: Membranoproliferative glomerulonephritis with polyarteritis: a case report.
abstract: A case of membranoproliferative glomerulonephritis with polyarteritis is described. The patient was a 68 year old male who had the disease for about four months. A kidney biopsy specimen taken just before the patient died was studied by light, immunofluorescence, and electron microscopy. Splitting of the basement membrane, IgG, IgA, BlC, Clq, fibrinogen, and electron dense deposits were found in the glomeruli. It is considered that perhaps some cases of membranoproliferative glomerulonephritis are produced by circulating immune complexes.
