| crescentic glomerulonephritis | <nephrology, pathology> A relatively uncommon (affecting 1 out of 10,000 people) form of acute glomerulonephritis that results in damage within the glomerulus of the kidney. There is rapid loss of kidney function with the formation of crescents on microscopic analysis (kidney biopsy). This disorder may result in acute glomerulonephritis or nephrotic syndrome, but ultimately results in renal failure and end-stage renal disease. Symptoms include smoky coloured urine (pyuria), decreased urine output, swelling and hypertension. Any conditions which can cause a vasculitis increase the risk of this disorder. Some examples include lupus, Goodpasture's syndrome, Henoch-Schonlein purpura, IgA nephropathy, membranoproliferative glomerulonephritis, anti-glomerular basement membrane antibody disease, history for malignant tumours and exposure to hydrocarbon solvents.

| segmental glomerulonephritis | Glomerulonephritis affecting only part of a glomerulus or glomeruli. Synonym: local glomerulonephritis. (05 Mar 2000) |
| hypocomplementemic glomerulonephritis | <pathology> A kidney disorder which results in kidney dysfunction. Inflammation of the glomeruli result from an abnormal immune response and the deposition of antibodies within the kidney (glomerulus) ultrastructure. Membranoproliferative glomerulonephritis has been divided into two different types in the basis of where the antibodies are deposited in the glomerulus. MPGN type I, the more common type, deposits antibodies in the subendothelial layer of the basement membrane, whereas type II deposits antibodies in the bottom layer of the basement membrane. Symptoms include cloudy urine (pyuria), decreased urine output, swelling and hypertension. This disorder often results in end-stage renal disease. Acronym: MPGN (26 Mar 1998) |

| subacute glomerulonephritis | Undesirable term for glomerulonephritis with proteinuria, haematuria and azotemia persisting for many weeks; renal changes are variable, including those of rapidly progressive and membranoproliferative glomerulonephritis. Synonym: subacute nephritis. (05 Mar 2000) |
| diffuse glomerulonephritis | Glomerulonephritis affecting most of the renal glomeruli; it may lead to azotemia. (05 Mar 2000) |
| immune complex glomerulonephritis | Immune complexes are deposited in the renal glomerulus where they bind complement and initiate an inflammatory process attracting neutrophils and macrophages resulting in an alteration of the basement layer of the kidney. The disease state can lead to ultimate destruction of the glomerulus and renal failure. (05 Mar 2000) |
| Ellis type 1 glomerulonephritis | An obsolete designation for glomerulonephritis presenting as acute glomerulonephritis, followed by complete recovery in most cases, or the development of rapidly progressive glomerulonephritis, or incomplete remission with persistent proteinuria and subsequent development of chronic glomerulonephritis. Synonym: Ellis type 1 nephritis. (05 Mar 2000) |
| Ellis type 2 glomerulonephritis | An obsolete designation for glomerulonephritis which is usually not related to preceding bacterial infection; characterised by an insidious onset of the nephrotic syndrome, failure of complete remission, and eventual development of chronic renal failure. The kidneys usually show membranous glomerulonephritis. Synonym: Ellis type 2 nephritis. (05 Mar 2000) |
| extramembranous glomerulonephritis | <pathology> A kidney disease that occurs due to inflammation of the kidney glomerulus and its basement membrane. The exact cause is unknown but it appears to be related to the deposition of immune complexes in the basement membrane leading to thickening of the capillary walls. This disorder is a common cause of nephrotic syndrome an is usually how the disease manifests. Risk factors include primary renal disease, malaria, hepatitis B, lupus, syphilis, cancers and non-Hodgkin's lymphomas. Risks also include exposure to some medications such as gold compounds and penicillamine. Mercury, trimethadione and some skin-lightening creams have also been implicated. Treatment includes systemic corticosteroids and immunosuppressive agents. (27 Sep 1997) |
| exudative glomerulonephritis | Glomerulonephritis with infiltration of glomeruli by polymorphonuclear leukocytes, occurring in acute glomerulonephritis. (05 Mar 2000) |
| lobular glomerulonephritis | <pathology> A kidney disorder which results in kidney dysfunction. Inflammation of the glomeruli result from an abnormal immune response and the deposition of antibodies within the kidney (glomerulus) ultrastructure. Membranoproliferative glomerulonephritis has been divided into two different types in the basis of where the antibodies are deposited in the glomerulus. MPGN type I, the more common type, deposits antibodies in the subendothelial layer of the basement membrane, whereas type II deposits antibodies in the bottom layer of the basement membrane.

| lupus glomerulonephritis-pathology | Patient survival and preservation of renal function are predictable from renal pathology as demonstrated by biopsy and defined by the histological classification of the International Study of Kidney Disease in Children/World Health Organization (ISKDC/WHO). Semi-quantitative indices of nephron loss (chronicity index) and activity of acute potentially reversible inflammation (activity index) are not predictive of individual outcome, renal failure or death in patients with aggressively treated SLE GN.
