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.
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.
[1] 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 ...
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 ]
IgM nephropathy or immunoglobulin M nephropathy (IgMN) is a kind of idiopathic glomerulonephritis that is marked by IgM diffuse deposits in the glomerular mesangium. [1] IgM nephropathy was initially documented in 1978 by two separate teams of researchers.
Nephropathy can be associated with some therapies used to treat cancer. The most common form of kidney disease in cancer patients is acute kidney injury (AKI) which can usually be due to volume depletion from vomiting and diarrhea that occur following chemotherapy or occasionally due to kidney toxicities of chemotherapeutic agents.
The changes are indistinguishable from those observed in IgA nephropathy.
