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 ...
Primary IgA nephropathy is characterized by deposition of the IgA antibody in the glomerulus. There are other diseases associated with glomerular IgA deposits, the most common being IgA vasculitis (formerly known as Henoch–Schönlein purpura [HSP]), which is considered by many to be a systemic form of IgA nephropathy. [ 3 ]
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 ...
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 complexes in different key areas throughout the body.
In cases where a cause can be determined, medications and infectious pathogens are most common in adults, while IgA vasculitis (Henoch–Schönlein purpura) frequently affects children. [6] Other etiologies include autoimmune conditions and malignancies, usually hematologic (related to the blood). [5] [6]
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 ...
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 ...
Henoch-Schönlein purpura (HSP, also known as allergic purpura) is a systemic vasculitis (inflammation of blood vessels) characterized by deposition of immune complexes containing the antibody IgA especially in the skin and kidney. Could try to make a bit smoother like:
