glomerular basement membrane thickening

Membranous glomerulonephritis Causes, symptoms, and

May 10, 2017Membranous glomerulonephritis causes continue to be researched, but what we can tell you is that nephropathy is caused by thickening of part of the kidney that filters waste and extra fluid from the blood. This part is called the glomerular basement membrane and unfortunately, the exact reason for the thickening of this membrane is still unknown.

The Glomerular Basement Membrane Abnormality In Alport's

The characteristic electron microscopic abnormality in Alport's syndrome is thickening of the glomerular basement membrane with splitting and lamellation of the lamina densa. It is commonly accompanied by severe attenuation of the basement membrane and sometimes by disruption of capillary walls. The ultrastructural abnormality is secondary to a more basic defect in the chemical structure of

Pathology. Nephrotic syndrome is a change in the structure of the glomerular filtration mechanism usually in the glomerular basement membrane. Some symptoms include proteinuria, hypoalbuminaemia, oedema, and hyperlipidemia. Diabetic glomerulosclerosis is a thickening of the basement membrane, which can become up to 4 5 times thicker

Glomerular basement membrane

The glomerular basement membrane (GBM) of the kidney is the basal lamina layer of the glomerulus. The glomerular endothelial cells, the GBM and the filtration slits between the podocytes perform the filtration function of the glomerulus, separating the blood in the capillaries from the filtrate that forms in Bowman's capsule.
