<unk>  <unk>  is a disease of kidney which occurs following severe damage to the kidneys and it can lead to rapid deterioration of kidney function in a few days. It is characterized by the presence of crescents in the glomeruli and hence is also called crescentic glomerulonephritis. Patients with<unk>  present with nephritic syndrome, but some may also have proteinuria.<unk>  progresses to end stage renal disease if it is not treated in time.<unk>  is classified into three types, all of which involve immune-mediated damage to the glomeruli. In type I<unk> , injury is caused by antibodies directed against the glomerular basement membrane. Type II<unk>  is characterized by the deposition of immune complexes in the glomerulus.  Type III, or pauci-immune<unk> , features antibodies directed against neutrophils (anti-neutrophil cytoplasmic antibodies, ANCA). Treatment depends on the underlying disease process. For example, plasmapheresis, corticosteroids, and cytotoxic drugs may promote recovery in Goodpasture syndrome, a cause of type I<unk> . Despite even early treatment, however, many patients with<unk>  may ultimately require dialysis and possibly renal transplant.
