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.
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 ...
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.
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 (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 ...
MesPGN often occurs as a result of glomerular injury, though can be idiopathic. MesPGN has been associated with disease processes such as: IgA nephropathy, IgM nephropathy, systemic lupus erythematous, Alport's syndrome, resolving post-infectious glomerulonephritis, and complement nephropathy, such as C1Q nephropathy. [1] IgA nephropathy is the ...
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.
When the glomeruli of the kidney from a patient with symptoms of proliferative nephritis are examined under the microscope, crescents will be normally observed. When these are subjected to immunofluorescence, three patterns can be observed: linear, granular and negative (pauci-immune). [ 1 ]
