    The changes are indistinguishable from those observed in IgA nephropathy. [12] Microphotograph of a histological section of human skin prepared for direct immunofluorescence using an anti-IgA antibody, the skin is a biopsy of a patient with Henoch–Schönlein purpura. IgA deposits are found in the walls of small superficial capillaries (yellow ...

    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.

  4. Nephritic syndrome - Wikipedia

    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 ...

  5. Glomerulonephritis - Wikipedia

    en.wikipedia.org/wiki/Glomerulonephritis

    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 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 ...

    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.

  8. Thin basement membrane disease - Wikipedia

    en.wikipedia.org/wiki/Thin_basement_membrane_disease

    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.

  9. Type III hypersensitivity - Wikipedia

    en.wikipedia.org/wiki/Type_III_hypersensitivity

    Immune complex glomerulonephritis, as seen in Henoch-Schönlein purpura; this is an example of IgA involvement in a nephropathy. The reaction can take hours, days, or even weeks to develop, depending on whether or not there is immunological memory of the precipitating antigen. Typically, clinical features emerge a week following initial antigen ...
