| nephritis | <nephrology> Inflammation of the kidney, a focal or diffuse proliferative or destructive process which may involve the glomerulus, tubule or interstitial renal tissue. Origin: Gr. Nephros = kidney (18 Nov 1997) |
|---|---|
| nephritis gravidarum | Nephritis developing in pregnancy. (05 Mar 2000) |
| nephritis, hereditary | Hereditary disease characterised initially by haematuria and slowly progressing to renal insufficiency. It is sometimes associated with perceptual deafness and/or congenital ocular defects. (12 Dec 1998) |
| nephritis, interstitial | Primary or secondary disease of the renal interstitial tissue resulting from arterial, arteriolar, glomerular, or tubular disease which destroys individual nephrons, or from toxic involvement of interstitital cells and tubules due to systemic diseases such as gout, to drug exposure, or to mercury poisoning. Clinically it may be manifested primarily by loss of concentrating capacity, mineral wasting, proteinuria, and abnormal urine sediment. It may be seen in an acute form, particularly after specific bacterial infection, and may result in acute papillary necrosis. More commonly, the process is a chronic one with progressive renal atrophy and diminution of renal function. (12 Dec 1998) |
| acute interstitial nephritis | <nephrology> A relatively uncommon condition which is characterised by inflammation of the renal tubules, glomeruli and surrounding tissue. Interstitial nephritis is usually be temporary and often associated with the use of a particular medication. Chronic and progressive forms do exist. Drugs that have been associated with interstitial nephritis include penicillins, ampicillin, sulpha drugs, non-steroidal anti-inflammatory agents, furosemide and thiazide diuretics. May result in mild kidney dysfunction or acute renal failure. Treatment may be with corticosteroids. Incidence: 1 in 25,000. (29 Dec 1997) |
|---|---|
| acute nephritis | <nephrology> A disease of the kidneys that results in inflammation of the glomerulus (the portion of the kidney that filters the blood). Conditions which may cause glomerulonephritis include post-streptococcal disease (strep throat), lupus, syphilis, bacterial endocarditis, membranoproliferative glomerulonephritis, sepsis, vasculitis, Goodpasture's syndrome, typhoid fever, Henoch-Schonlein purpura, hepatitis or a viral infection (for example mumps, measles, mononucleosis). (27 Sep 1997) |
| analgesic nephritis | Chronic interstitial nephritis with renal papillary necrosis, occurring in patients with a long history of excessive consumption of analgesics, especially those containing phenacetin. Synonym: analgesic nephropathy. (05 Mar 2000) |
| anti-basement membrane nephritis | Glomerulonephritis produced by autologous or heterologous antibodies to the glomerular capillary basement membranes, the latter known as anti-kidney serum nephritis. (05 Mar 2000) |
| anti-kidney serum nephritis | Experimental glomerulonephritis produced by injection of antiserum to kidney. (05 Mar 2000) |
| Masugi's nephritis | Glomerulonephritis produced by injecting into rats a rabbit antiserum prepared against rat kidney tissue suspensions. (05 Mar 2000) |
| glomerular nephritis | <nephrology> A variety of nephritis characterised by inflammation of the capillary loops in the glomeruli of the kidney. It occurs in acute, subacute and chronic forms and may be secondary to haemolytic streptococcal infection. Evidence also supports possible immune or autoimmune mechanisms. (18 Nov 1997) |
| mesangial nephritis | Glomerulonephritis with an increase in glomerular mesangial cells or matrix, or mesangial deposits. (05 Mar 2000) |
| chronic nephritis | Glomerulonephritis that presents with persisting proteinuria, chronic renal failure, and hypertension, of insidious onset or as a late sequel of acute glomerulonephritis; the kidneys are symmetrically contracted and granular, with scarring and loss of glomeruli and the presence of tubular atrophy and interstitial fibrosis. Synonym: chronic nephritis. (05 Mar 2000) |
| haemorrhagic nephritis | Acute glomerulonephritis accompanied by haematuria. (05 Mar 2000) |
| salt-losing nephritis | A rare disorder resulting from renal tubular damage of a variety of aetiologies; mimics adrenocortical insufficiency in that abnormal renal loss of sodium chloride occurs, accompanied by hyponatraemia, azotemia, acidosis, dehydration, and vascular collapse. Synonym: salt-losing syndrome, Thorn's syndrome. (05 Mar 2000) |
| hereditary nephritis | <pathology> An inherited disorder involving damage to the kidneys, haematuria and hearing loss. In some individuals vision may also be affected. This genetic disease is uncommon. Symptoms include loss of hearing, abnormal colour to urine, swelling, cough and decline in vision. Inheritance: sex-linked autosomal dominant. Incidence: 1 in 50,000. (27 Sep 1997) |
| scarlatinal nephritis | Acute glomerulonephritis occurring as a complication of scarlet fever. (05 Mar 2000) |
| serum nephritis | Glomerulonephritis occurring in serum sickness or in animals injected with foreign serum protein. (05 Mar 2000) |
| subacute nephritis | 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) |
