1 causes of infection caused by Henoch Schonlein purpura nephritis:
Including bacteria, viruses and parasites or Schistosoma infection. About 1/3 of patients before the onset of infection, the most common respiratory tract infection.

Food, Yao, bacteria, viruses, toxins caused by immune complex formation and deposition in the kidney, inducing immune injury and vascular inflammation. A large number of researches indicate allergic purpura nephritis is a complex disease: immune serum in patients with HSP can be detected in circulating immune complexes; skin microvascular and mesenteric vascular lesions showed glomerular, allergic vasculitis, vascular lesions and glomerular IgA positive, C3 granule calm; HSP patients transplanted kidney and normal kidney transplanted the same lesions. IgA plays an important role in its pathogenesis.
