No immune deposits can be seen on staining, however blood tests may be positive for the ANCA antibody. [4]: 558–559 Histopathologically, the majority of glomeruli present "crescents". Formation of crescents is initiated by passage of fibrin into the Bowman space as a result of increased permeability of glomerular basement membrane.
Glomerulonephrosis is a non-inflammatory disease of the kidney presenting primarily in the glomerulus (a glomerulopathy) as nephrotic syndrome.The nephron is the functional unit of the kidney and it contains the glomerulus, which acts as a filter for blood to retain proteins and blood lipids.
Acute proliferative glomerulonephritis is a disorder of the small blood vessels of the kidney.It is a common complication of bacterial infections, typically skin infection by Streptococcus bacteria types 12, 4 and 1 but also after streptococcal pharyngitis, for which it is also known as postinfectious glomerulonephritis (PIGN) or poststreptococcal glomerulonephritis (PSGN).

Kidney disease results from kidney damage and subsequent decline in kidney function. ... Budhiraja says that other forms of kidney disease and inflammatory disorders such as glomerulonephritis can ...
IgA nephropathy (IgAN), also known as Berger's disease (/ b ɛər ˈ ʒ eɪ /) (and variations), or synpharyngitic glomerulonephritis, is a disease of the kidney (or nephropathy) and the immune system; specifically it is a form of glomerulonephritis or an inflammation of the glomeruli of the kidney.
Glomerulonephritis is characterized by inflammation and thinning of the glomerular basement membrane and the occurrence of small pores in the podocytes of the glomerulus. These pores become large enough to permit both proteins and red blood cells to pass into the urine (yielding proteinuria and hematuria, respectively).
Rapidly progressive glomerulonephritis (RPGN) is a syndrome of the kidney that is characterized by a rapid loss of kidney function, [4] [5] (usually a 50% decline in the glomerular filtration rate (GFR) within 3 months) [5] with glomerular crescent formation seen in at least 50% [5] or 75% [4] of glomeruli seen on kidney biopsies.
Since it is a result of SLE, this type of glomerulonephritis is said to be secondary, and has a different pattern and outcome from conditions with a primary cause originating in the kidney. [5] [2] The diagnosis of lupus nephritis depends on blood tests, urinalysis, X-rays, ultrasound scans of the kidneys, and a kidney biopsy.
