diffuse glomerulonephritis

glomerulonephritis

[glo-mer″u-lo-nĕ-fri´tis] a variety of nephritis characterized 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 an infection, especially with the hemolytic streptococcus.

Histologic appearance of acute glomerulonephritis. A, Normal glomerulus. B, Glomerulonephritis. The glomerulus appears hypercellular and the capillaries are narrowed or occluded. From Damjanov, 2000.diffuse glomerulonephritis a severe form of glomerulonephritis with proliferative changes in more than half the glomeruli, frequently with epithelial crescent formation and necrosis; it is often seen in cases of advanced systemic lupus erythematosus.IgA glomerulonephritis IgA nephropathy.lobular glomerulonephritis (membranoproliferative glomerulonephritis) a chronic glomerulonephritis characterized by mesangial cell proliferation and irregular thickening of the glomerular capillary wall. There are two subtypes: Type I is marked by subendothelial deposits and activation of the classic complement pathway. Type II is marked by heavy deposits in the glomerular basement membrane and activation of the alternative complement pathway. Both types occur in older children and young adults and follow a slowly progressing course with irregular remissions ultimately resulting in renal failure.membranous glomerulonephritis a form characterized by proteinaceous deposits on the glomerular capillary membrane" >basement membrane or by thickening of the membrane, with circulating complexes" >antigen-antibody complexes indicating immune complex disease; it may be secondary to any of numerous other conditions. In some cases it may develop into the nephrotic syndrome. Called also membranous nephropathy.mesangiocapillary glomerulonephritis membranoproliferative glomerulonephritis.rapidly progressive glomerulonephritis acute glomerulonephritis marked by a rapid progression to end-stage renal disease and histologically by profuse epithelial proliferation, often with epithelial crescents; principal signs are anuria, proteinuria, hematuria, and anemia. Plasmapheresis or high doses of corticosteroids may lead to recovery of renal function.

dif·fuse glo·mer·u·lo·ne·phri·tis

glomerulonephritis affecting most of the renal glomeruli; it may lead to azotemia.

dif·fuse glo·mer·u·lo·neph·ri·tis

(di-fyūs glō-meryū-lō-nef-rītis) Glomerulonephritis affecting most of the renal glomeruli; it may lead to azotemia.
