• A renal disorder characterized by damage in the glomeruli. It may be acute or chronic, focal or diffuse, and it may lead to renal failure. Causes include autoimmune disorders, infections, diabetes, and malignancies.

• Inflammation of the renal glomeruli (KIDNEY GLOMERULUS) that can be classified by the type of glomerular injuries including antibody deposition, complement activation, cellular proliferation, and glomerulosclerosis. These structural and functional abnormalities usually lead to HEMATURIA; PROTEINURIA; HYPERTENSION; and RENAL INSUFFICIENCY.

• Inflammatory changes in the renal glomeruli characterized by thickening of the glomerular basement membrane, mesangial cell proliferation and/or mononuclear inflammatory cell infiltration. In some forms, the glomerular epithelial cells may also proliferate and form adhesions.

• Glomerulonephritis is a disorder of glomeruli (clusters of microscopic blood vessels in the kidneys with small pores through which blood is filtered). It is characterized by body tissue swelling (edema), high blood pressure, and the presence of red blood cells in the urine.

• Glomerulonephritis (gloe-mer-u-low-nuh-FRY-tis) is inflammation of the tiny filters in your kidneys (glomeruli). Glomeruli remove excess fluid, electrolytes and waste from your bloodstream and pass them into your urine. Glomerulonephritis can come on suddenly (acute) or gradually (chronic).

• Glomerulonephritis is a type of kidney disease in which there is inflammation of the glomeruli, the tiny filters that remove excess waste and fluids from the blood. It may be acute or chronic (coming on gradually), and may occur on its own (primary) or be caused by another condition (secondary). Signs and symptoms may depend on the type...

• Glomerulonephritis (GN) denotes glomerular injury and applies to a group of diseases, which are generally, but not always, characterized by inflammatory changes in the glomerular capillaries and the glomerular basement membrane (GBM). The injury can involve a part or all of the glomeruli or the glomerular tuft. The inflammatory changes...
