  2. Pauci-immune - Wikipedia

    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 ...

    en.wikipedia.org/wiki/Microscopic_polyangiitis

    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 ...

  4. Glomerulonephritis - Wikipedia

    en.wikipedia.org/wiki/Glomerulonephritis

    Type 3 rapidly progressive glomerulonephritis, also called pauciimmune type, is associated with causes of vascular inflammation including granulomatosis with polyangiitis (GPA) and microscopic polyangiitis. No immune deposits can be seen on staining, however blood tests may be positive for the ANCA antibody. [4]: 558–559

  5. Rapidly progressive glomerulonephritis - Wikipedia

    en.wikipedia.org/wiki/Rapidly_progressive...

    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.

    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. [2]

  7. Diffuse proliferative nephritis - Wikipedia

    en.wikipedia.org/wiki/Diffuse_proliferative...

    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]

  8. Acute proliferative glomerulonephritis - Wikipedia

    en.wikipedia.org/wiki/Acute_proliferative...

    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]

  9. Nephritic syndrome - Wikipedia

    en.wikipedia.org/wiki/Nephritic_syndrome

    Nephritic syndrome is a syndrome comprising signs of nephritis, which is kidney disease involving inflammation. It often occurs in the glomerulus, where it is called glomerulonephritis. Glomerulonephritis is characterized by inflammation and thinning of the glomerular basement membrane and the occurrence of small pores in the podocytes of the ...
