Characterized by deposition of immune complexes in glomerular tissues, type II RPGN accounts for 40 [11] % of cases. Any immune complex disease—including systemic lupus erythematosus, acute proliferative glomerulonephritis, Henoch–Schönlein purpura, and IgA nephropathy—that involves the glomerulus may progress to RPGN if severe enough.

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 ...
Glomerulonephritis (GN) is a term used to refer to several kidney diseases (usually affecting both kidneys). Many of the diseases are characterised by inflammation either of the glomeruli or of the small blood vessels in the kidneys, hence the name, [ 1 ] but not all diseases necessarily have an inflammatory component.
In 2014 a study was completed to diagnose glomerulonephritis based on etiology. Using immunofluorescence and light microscopy, the investigators were determining the classification for the disease based on if the disease was immune complex mediated, pauci- immune, or complement mediated.
Microscopic polyangiitis is an autoimmune disease characterized by a systemic, pauci-immune, necrotizing, small-vessel vasculitis without clinical or pathological evidence of granulomatous inflammation.
Over the ensuing decade, Falk and his colleagues have more fully documented the pathogenicity of ANCA. In 2002, they demonstrated in a mouse model that passively transferred anti-myeloperoxidase antibodies were capable of inducing pauci-immune necrotizing and crescentic glomerulonephritis. [9]
More than 1 million Americans live with human immunodeficiency virus, or HIV, with tens of thousands of new diagnoses each year. But with earlier diagnoses and advances in treatment, HIV, the ...
English: What is rapidly progressive glomerulonephritis (RPGN; crescentic glomerulonephritis)? RPGN's a syndrome of the kidney that's characterized by proliferation of epithelial cells that form a crescent shape, and these changes can ultimately lead to acute renal failure.
