He recognised the role of allergy in the pathogenesis of Henoch-Schonlein purpura, hence the understanding of the allergic component in HSP. [34] William Osler is also the first to recognise the underlying allergic mechanism of HSP. [35] In 2012, the International Chapel Hill Consensus Conference Nomenclature of Vasculitides renamed HSP IgA ...

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 ...
Cryofibrinogenemia refers to a condition classified as a fibrinogen disorder in which a person's blood plasma is allowed to cool substantially (i.e. from its normal temperature of 37 °C to the near-freezing temperature of 4 °C), causing the (reversible) precipitation of a complex containing fibrinogen, fibrin, fibronectin, and, occasionally, small amounts of fibrin split products, albumin ...
IgA nephropathy (IgAN), also known as Berger's disease (/ b ɛər ˈ ʒ eɪ /) (and variations), or synpharyngitic glomerulonephritis, is a disease of the kidney (or nephropathy) and the immune system; specifically it is a form of glomerulonephritis or an inflammation of the glomeruli of the kidney.
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]
Purpura (/ ˈ p ɜːr p jʊər ə / [1]) is a condition of red or purple discolored spots on the skin that do not blanch on applying pressure. The spots are caused by bleeding underneath the skin secondary to platelet disorders, vascular disorders, coagulation disorders, or other causes. [ 2 ]
