glomerulonephritis /glo·mer·u·lo·ne·phri·tis/ (glo-mer″u-lo-nĕ-fri´tis) nephritis with inflammation of the capillary loops in the renal glomeruli.

---

acute glomerulonephritis  an acute form characterized by proteinuria, edema, hematuria, renal failure, and hypertension, sometimes preceded by tonsillitis or febrile pharyngitis.

chronic glomerulonephritis  a slowly progressive glomerulonephritis generally leading to irreversible renal failure.

diffuse glomerulonephritis  a severe form with proliferative changes in more than half the glomeruli, often with epithelial crescent formation and necrosis; often seen in advanced systemic lupus erythematosus.

IgA glomerulonephritis  IgA nephropathy; a chronic form marked by a hematuria and proteinuria and by deposits of immunoglobulin A in the mesangial areas of the renal glomeruli, with subsequent reactive hyperplasia of mesangial cells.

lobular glomerulonephritis , membranoproliferative glomerulonephritis a chronic, slowly progressive glomerulonephritis in which the glomeruli are enlarged as a result of proliferation of mesangial cells and irregular thickening of the capillary walls, which narrows the capillary lumina.

membranous glomerulonephritis  a form characterized histologically by proteinaceous deposits on the glomerular capillary basement membrane or by thickening of the membrane; clinically resembling chronic glomerulonephritis, occasionally with transient nephrotic syndrome.

mesangiocapillary glomerulonephritis  membranoproliferative g.
