Ontology: Glomerulonephritis (C0017658)

Definition (NCI) 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.
Definition (CSP) glomerular disease characterized by an inflammatory reaction, with leukocyte infiltration and cellular proliferation of the glomeruli, or that appears to be the result of immune glomerular injury.
Definition (MSH) 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.
