It mostly affects children aged 2–10 years, and boys are affected more often than girls. Rarely, it can affect the lungs and central nervous system. IgA nephropathy (or ‘IgA’ for short) is a kidney disorder that occurs when IgA – a protein that normally helps the body fight infection – settles in the kidneys. The is thought to start with defective glycosylation of IgA subclass IgA1 that results in overproduction of galactose-deficient IgA1 (Gd-IgA1), occurrence of anti-Gd-IgA1 autoantibodies, and mesangial deposition of nephritogenic immune complexes. IgA vasculitis most commonly occurs in children 10 years of age and affects multiple organ systems (palpable purpura, abdominal pain, arthralgia).

Typically, proteinuria (protein in the urine) and/or hematuria (blood in the urine) are the first symptoms seen in patients with IgA nephropathy. It is characterized by the deposition of IgA1 (in particular, galactose-deficient IgA1) in the mesangial area of the glomeruli. IgA nephropathy (or Berger's Disease) is a condition in which a protein can cause damage to the kidneys. What is IgA nephropathy? IgA nephropathy (or ‘IgA’ for short) is a kidney disorder that occurs when IgA – a protein that normally helps the body fight infection – settles in the kidneys. In IgA nephropathy, the antibodies do not attack tissue directly, but they do cause inflammation that can inhibit the kidneys’ ability to filter wastes from the blood over time.

LAS VEGAS – IgA vasculitis has a reputation as an illness of childhood, but rheumatologist Alexandra Villa-Forte, MD, MPH, cautioned colleagues that it can strike adults, too, often in a much more severe form.

IgA vasculitis and IgA nephropathy probably share a similar immunopathogenic mechanism that involves abnormally glycosylated IgA1. 59–62 Patients with IgA vasculitis and IgA nephropathy have increased serum levels of IgA1 with galactose-deficient hinge regions, and the vascular immune complexes contain this abnormal IgA1 but little or no IgA2. IgA nephropathy (IgAN) is defined by the presence of dominant or co-dominant mesangial IgA immune deposits, often accompanied by C3 and IgG in association with a mesangial proliferative glomerulonephritis of varying severity.
