Association of the infectious triggers with childhood Henoch–Schonlein purpura in Anhui province, China

IgA Vasculitis With Nephritis (Henoch−Schönlein Purpura) in a COVID-19 Patient

“…IgA vasculitis (Henoch-Schönlein purpura) is a small-vessel vasculitis mediated by immune-complexes deposits containing IgA. It is usually preceded by respiratory tract infections and its association with multiple microorganisms is known, including different viruses 8 . The main clinical manifestations are nonthrombocytopenic purpura, arthritis/arthralgia, and abdominal pain 8,9,S1,S2 .…”

Epstein–barr Virus‐associated Haemorrhagic Bullous Henoch–schonlein Purpura

“…Infections may be one of the several possible triggers participating in the pathogenesis; the most common infectious trigger detected was streptococcal infections. 2 Although there are a few reports of EBV infection in children with HSP, 3 to our knowledge, this is the first report of EBV-associated haemorrhagic bullous HSP. Deposition of IgA or C3 in skin biopsy materials is diagnostic for HSP.…”

A Case of Adult-onset Henoch-Schönlein Purpura Triggered by Fire Ants

“…The purpura are often palpable, erythematous and of varying sizes. Skin biopsy and subsequent histopathological analysis demonstrate areas of leukocytoclastic vasculitis, and immunofluorescence shows IgA deposition in vessel walls [4][5][6].…”

“…There have been several cases of HSP presenting with antecedent immunological insult, such as a bacterial or viral infection. One study by Albaramki showed that 41.9% of patients with HSP presented with a preceding upper respiratory tract infection [1,4]. Incidents of purpura following infection with streptococcus, Epstein-Barr virus (EBV) and varicella have also been documented.…”
