| 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. (27 Sep 1997) |

| Ellis type 1 nephritis | 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 nephritis | 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) |
| transfusion nephritis | Renal failure and tubular damage resulting from the transfusion of incompatible blood; the haemoglobin of the haemolyzed red cells is deposited as casts in the renal tubules. (05 Mar 2000) |
| trench nephritis | An obsolete term for glomerulonephritis occurring in soldiers subjected to cold and damp conditions in trenches. (05 Mar 2000) |
| tuberculous nephritis | Nephritis, mainly interstitial, due to the tubercle bacillus. (05 Mar 2000) |
| tubulointerstitial nephritis | Nephritis affecting renal tubules and interstitial tissue, with infiltration by plasma cells and mononuclear cells; seen in lupus nephritis, allograft rejection, and methicillin sensitization. (05 Mar 2000) |
| uranium nephritis | An experimental nephritis produced by the administration of uranium nitrate. (05 Mar 2000) |
| focal nephritis | Glomerulonephritis affecting a small proportion of renal glomeruli which commonly presents with haematuria and may be associated with acute upper respiratory infection in young males, not usually due to streptococci; associated with IgA deposits in the glomerular mesangium and may also be associated with systemic disease, as in Henoch-Schonlein purpura. Synonym: Berger's disease, Berger's focal glomerulonephritis, focal nephritis, IgA nephropathy. (05 Mar 2000) |
| lupus nephritis | Glomerulonephritis associated with systemic lupus erythematosus. It is classified into four histologic types: mesangial, focal, diffuse, and membranous. (12 Dec 1998) |
