IgA nephropathy is the most common glomerulonephritis worldwide; the global incidence is 2.5/100,000 per year amongst adults. [1] Aggressive Berger's disease is on the NORD list of rare diseases. [2] Primary IgA nephropathy is characterized by deposition of the IgA antibody in the glomerulus.
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 ...
In IgA nephropathy, episodes of frank hematuria are more common, and a family history is less common. A kidney biopsy is the only way to diagnose thin basement membrane disease. It reveals thinning of the glomerular basement membrane from the normal 300 to 400 nanometers (nm) to 150 to 250 nm
IgA exists in two isotypes, IgA1 and IgA2.They are both heavily glycosylated proteins. [9] While IgA1 predominates in serum (~80%), IgA2 percentages are higher in secretions than in serum (~35% in secretions); [10] the ratio of IgA1 and IgA2 secreting cells varies in the different lymphoid tissues of the human body: [11]
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 ...
The symptoms at onset are very similar to IgA nephropathy and include abdominal pain, hematuria, edema, and oliguria. [ 18 ] Henoch–Schönlein purpura (HSP) - Often considered a systemic form of IgA nephropathy , Henoch–Schönlein purpura (HSP) is a systemic small-vessel vasculitis that is characterized by deposition of IgA antibody immune ...
English: What is IgA nephropathy? IgA nephropathy, sometimes called Berger disease, is a type of nephritic syndrome where abnormal IgA antibody is formed, which results in immune complex deposition in the glomerular mesangium, leading to kidney disease. This video covers the pathophysiology, signs and symptoms, and treatment of IgA nephropathy.
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.
