  • Title: An ultrastructural morphometric study of membranous glomerulonephritis.
    Author: Aparicio SR, Woolgar AE, Aparicio SA, Watkins A, Davison AM.
    Journal: Nephrol Dial Transplant; 1986; 1(1):22-30. PubMed ID: 3110660.
    Abstract:
    Sixteen cases of membranous glomerulonephritis and 17 controls were studied using electron microscopy and morphometry of whole glomerular cross-sections. It was found that, in relation to controls, in membranous glomerulonephritis the following parameters are increased: total area, total number of cells, all basement membrane parameters, visceral epithelium compartment area and visceral epithelial cell area, area of parietal epithelium, mesangium and urinary space, number of endothelial and mesangial cells; by contrast, the following are decreased: number of visceral epithelial cells, capillary and endothelial volume fractions. Correlation analysis between morphometric and clinical parameters demonstrated significant correlations between capillary basement membrane thickening and duration of disease, proteinuria and renal function; the changes in visceral epithelial cells correlated with serum albumin, proteinuria and inverse of creatinine; changes in relative area of capillary lumina correlated with blood pressure. It is concluded that the ultrastructural morphometric study of renal biopsies will lead to better understanding of glomerular disease.
