Rapidly progressive glomerulonephritis (RPGN) is one of the few nephrological emergency. However, it fortunately only affects 1-4% of all cases of glomerulonephritis. It is a clinical syndrome that includes signs and symptoms of glomerulonephritis, including hematuria, proteinuria, and edema with signs of renal failure and diffuse crescent formation on histopathology. Without appropriate treatment, RPGN progresses into end-stage renal disease within several days to only a few months yielding a very poor prognosis and renal outcome. RPGN is classified based on the presence of absence of anti-neutrophil cytoplasmic antibody (ANCA) and anti-GBM antibodies. Due to its rarity, the pathogenesis of RPGN is poorly understood and most probably is related to the type of RPGN and the circulating antibodies associated with each type. Evidence on treatment options for RPGN is poor; but the use of glucocorticoids and cyclophosphamide is currently recommended. Basic research and clinical data are currently emerging to better understand the disease pathogenesis and optimal therapeutic options.

==[[Rapidly progressive glomerulonephritis classification|Classification]]==
===Old Classification===
Following its initial description in 1914, crescenteric glomerulonephritis was first classified by Couser in 1988 based on features of immunofluorescence.<ref name="pmid3287904">{{cite journal| author=Couser WG|title=Rapidly progressive glomerulonephritis: classification, pathogenetic mechanisms, and therapy. |journal=Am J Kidney Dis | year= 1988 | volume= 11 | issue= 6 | pages= 449-64 | pmid=3287904 | doi= | pmc=| url=http://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=3287904 }} </ref>
====Type I: Anti-GBM glomerulonephritis: 20% of patients====
Presence of linear staining of glomerular basement membrane (GBM)
====Type II: Pauci-immune glomerulonephritis: 50% of patients====
Absent or minimal immune deposits
====Type III: Immune complex-mediated glomerulonephritis: 30% of patients====
Presence of granular patterns of immune deposits within the glomerulus. Immune deposition may be associated with any of the following conditions:
*Infections
*Systemic illnesses
*Other primary glomerular diseases
====New Classification====
Upon the detection of new serological markers such as anti-GBM antibodies and anti-neutrophil cytoplasmic antibodies (ANCA)<ref name="pmid9744974">{{cite journal| author=Hricik DE, Chung-Park M, Sedor JR| title=Glomerulonephritis. | journal=N Engl J Med | year= 1998 | volume= 339 | issue= 13 | pages= 888-99 | pmid=9744974 | doi=10.1056/NEJM199809243391306 | pmc= | url=http://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=9744974 }} </ref>, the classification of RPGN has changed to involve several types of primary glomerulonephritis that correspond to the quantity and quality of such findings in patients’ sera. ANCA and anti-GBM may co-exist in approximately 20% of the patients.<ref name="pmid7544065">{{cite journal| author=Short AK, Esnault VL, Lockwood CM| title=Anti-neutrophil cytoplasm antibodies and anti-glomerular basement membrane antibodies: two coexisting distinct autoreactivities detectable in patients with rapidly progressive glomerulonephritis. | journal=Am J Kidney Dis | year= 1995 | volume= 26 | issue= 3 | pages= 439-45 | pmid=7544065 | doi= | pmc= | url=http://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=7544065 }} </ref>
====Type I====
Anti-GBM disease
*Anti-GBM antibody-mediated without pulmonary involvement
*Goodpasture’s disease: Anti-GBM antibody-mediated with pulmonary hemorrhage
====Type II====
Immune complex-mediated disease
====Type III====
Pauci-immune disease (ANCA positive)
*Idiopathic renal-limited vasculitis / renal-limited necrotizing crescenteric glomerulonephritis (NCGN)
*Granulomatosis with polyangitis (formerly “Wegener’s granulomatosis")
*Microscopic polyangiitis
*Churg-Strauss syndrome
====Type IV====
Mixed anti-GBM and ANCA associated disease 
====Type V====
Pauci-immune (ANCA negative)
