Glomerulonephritis (GN) denotes glomerular injury and applies to a group of diseases that are generally, but not always, characterised by inflammatory changes in the glomerular capillaries and the glomerular basement membrane (GBM). The injury can involve a part or all of the glomeruli or the glomerular tuft. The inflammatory changes are mostly immune mediated.   Diseases include membranous GN, minimal change disease, focal and segmental glomerulosclerosis, immunoglobulin A nephropathy, forms of rapidly progressive GN (vasculitis and anti-GBM disease), and systemic lupus erythematosus nephritis as the more common forms; and glomerular damage in other systemic diseases such as diabetes, amyloidosis, myeloma, and a variety of infections.
