Reports from Postgraduate Institute of Medical Education and Research add new data to research in membranous glomerulonephritis
2007 AUG 20 -- A report, "Glomerular morphometry in biopsy evaluation of minimal change disease, membranous glomerulonephritis, thin basement membrane disease and Alport's syndrome," is newly published data in Analytical and Quantitative Cytology and Histology. In this recent report published in the journal Analytical and Quantitative Cytology and Histology, researchers in Chandigarh, India conducted a study "To assess the role of glomerular morphometry in biopsy evaluation in renal disorders in addition to conventional diagnostic procedures. The study includes 10 cases each of minimal change disease (MCD), idiopathic membranous glomerulonephritis (idiopathic MGN), thin basement membrane disease (TBMD) and Alport's syndrome. Renal biopsies for normal study were obtained from age-and sex-matched autopsy cases without any renal disorder, confirmed histologically and ultrastructurally." "Glomerular morphometry was performed by semiautomatic procedure using Quantimet-600 image analysis system (Leica, Cambridge, United Kingdom). Morphometric findings revealed significant increase in glomerular "diameter and area" and "tuft diameter and area" in patients of idiopathic MGN, but no significant difference was found in patients of MCD, TBMD and Alport's syndrome. Evaluation of glomerular volume fractions revealed a decrease in capillary space volume fraction and an increase in "membranes and mesangial matrix" volume fraction in patients with idiopathic MGN. Significant decrease in capillary space volume fraction was also observed in patients of MCD," wrote C.S. Rayat and colleagues, Postgraduate Institute of Medical Education and Research. The researchers concluded: "Patients with Alport's syndrome showed variable changes. Glomerular morphometry could be considered as an adjunct to the diagnostic armamentarium of light microscopy, immunofluorescence and electron microscopy because it provides deep insight into quantitative parameters." Rayat and colleagues published their study in Analytical and Quantitative Cytology and Histology (Glomerular morphometry in biopsy evaluation of minimal change disease, membranous glomerulonephritis, thin basement membrane disease and Alport's syndrome. Analytical and Quantitative Cytology and Histology, 2007;29(3):173-82). For additional information, contact C.S.
