ABSTRACT

Objective To study the clinical characteristics of Henoch-Sch(o)nlein purpura (HSP) in children.Methods We retrospectively analyzed the clinical data of 124 children with HSP.Results Among these 124 children,54.84% of the children presented upper respiratory tract infection before the onset of HSP.The purpura recurred in 30 of 47 children with Henoch-Sch(o)nlein purpura nephritis and in 22 of 77 children without Henoch-Schonlein purpura nephritis,respectively (P＜0.05).The incidence of Henoch-Sch(o)nlein purpura nephritis was significantly higher in children who had purpura,gastrointestinal symptoms,and joint symptoms simultaneously than in those only with purpura (P＜0.05).The elevated levels of IgA and C reactive protein were found in 67.35% and 39.39% of the children,respectively.Conclusion The most important predisposing factor of HSP is upper respiratory tract infection.The children with recurrence of purpura or those who have purpura,gastrointestinal symptoms,and joint symptoms simultaneously are more likely to present renal damage.
