Henoch-Schönlein purpura (HSP) is a common systemic vasculitis in children. Animal models of HSP are needed to better understand the mechanism of HSP. Here, we investigated hematologic and immunologic profiles in HSP rat and rabbit models. Models were established with ovalbumin (OVA) based on type III hypersensitivity. During the acute phase, the models exhibited varying degrees of cutaneous purpura, joint inflammatory response, gastrointestinal bleeding, glomerular capsule protein exudation, vascular dilatation, and increased IgA expression and immune complex deposition. Twenty four hours after antigen challenge, compared with the controls, the models showed a significantly increased white blood cell count and granulocytes count and percentage, decreased number and percentage of lymphocytes, no change in platelet concentration, significantly increased serum IL-4 and TNF-α levels, and decreased CD4+ T cell, CD4/CD8 ratio, and C3 and C4 levels. Compared with the hematologic and immunologic profiles in pediatric HSP patients, the rat and rabbit HSP models can mimic pediatric HSP characteristics. Our studies provide two useful animal models for further investigations of the pathogenesis, diagnosis, drug screening and treatment of HSP. [ABSTRACT FROM AUTHOR] |
