When these are subjected to immunofluorescence, three patterns can be observed: linear, granular and negative (pauci-immune). [1] The linear and granular patterns are examples of positive immunofluorescence that are associated as follows: Goodpasture syndrome (linear pattern), post-streptococcal glomerulonephritis (granular), and diffuse ...
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.
As the glomerulonephritis progresses, the tubules of the kidney become infected, leading to atrophy and hyalinisation. The kidney appears to shrink. Treatment with corticosteroids is attempted if the disease progresses. [citation needed] In extremely rare cases, the disease has been known to run in families, usually passed down through the females.
These presenting symptoms are relatively non-specific and are often seen in other glomerular disorders. Preceding upper respiratory tract infection or post-streptococcal glomerulonephritis may contribute to hematuria, as both have been identified in patients presenting with hematuria in the context of mesangial proliferative glomerulonephritis.

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). [4]
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.
Clinical features may include constitutional symptoms like fever, arthralgia, myalgia, loss of appetite, weight loss and fatigue.A variety of organs can be affected, which causes a wide range of symptoms such as cough, shortness of breath, hemoptysis (coughing up of blood), symptoms of kidney failure, skin manifestations (palpable purpura and livedo racemosa [1]), seizures or peripheral ...
The cause of diffuse proliferative glomerulonephritis (DPGN) depends on the severity of the disease. DPGN is a secondary disease, in that a disease that a patient already has causes DPGN to occur. The most common associated disease of DPGN is severe systemic lupus erythematosus(SLE). [4] Specifically, Lupus nephritis class IV. [5]
