Glomerulonephritis is a type of nephritis which is accompanied by in flammation of the capillary loops in the glomeruli of the kidney. It occurs in acute, subacute, and chronic forms and may be secondary to hemoytic streptococcal infection. Evidence also supports possible autoimmune mechanisms. (Epidemiology »)
Pauci-immune crescentic glomerulonephritis (also called pauci-immune rapidly progressive gromerulonephritis) is a rapidly progressive form characterized by the presence of epithelial crescents and antineutrophil cytoplasmic antibodies, but few, if any, immune deposits.
Rapidly progressive glomerulonephritis (also called crescentic glomerulonephritis) is an acute form marked by a rapid progression to end-stage renal failure and, histologically, by profuse epithelial proliferation, often with epithelial crescents. Principal signs are anuria, proteinuria, hematuria, and anemia.
Other forms of glomerulonephritis exist but are not listed here (see specialist literature).
