IgA nephropathy, also known as Berger's disease, is the most common type of glomerulonephritis, and generally presents with isolated visible or occult hematuria, occasionally combined with low grade proteinuria, and rarely causes a nephritic syndrome characterised by proteinuria, and visible blood in the urine. IgA nephropathy is classically ...
Treatment Corticosteroids 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 ...
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.
IgA nephropathy (Note: Contrast time of onset with Post-streptococcal Glomerulonephritis) - Most commonly diagnosed in children who recently had an upper respiratory tract infection (URI). Symptoms typically present within 1–2 days of a non-specific URI with severe flank / abdominal pain, gross hematuria (characterized by dark brown or red ...
The other commonly associated disease is Immunoglobulin A (IgA) nephropathy. Post-infectious glomerulonephritis can also be caused by bacterial or viral infections. Streptococcal throat or skin infection is most commonly seen as the origin if glomerulonephritis is going to be caused by an infection. [ 6 ]
IgA nephropathy is the most common cause of MesPGN. [3] It is thought abnormally glycosylated IgA form polymers and deposit in the mesangium. [3] Subsequently, IgA immune complexes bind to IgA receptors on mesangial cells and induce injury to mesangial cells through release of cytokines and growth factors that promote infiltration of leukocytes ...
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).

The changes are indistinguishable from those observed in IgA nephropathy.

IgA deposits are found in the walls of small superficial capillaries (yellow ...
