目的探讨高凝状态与IgA血管炎肾炎(immunoglobulin A vasculitis with nephritis,IgAVN)患儿尿蛋白和肾脏病理损伤之间的关系。方法根据凝血功能结果,将349例IgAV患儿分为高凝组(52例)和非高凝组(297例),比较两组间尿蛋白和肾脏病理特征...目的探讨高凝状态与IgA血管炎肾炎(immunoglobulin A vasculitis with nephritis,IgAVN)患儿尿蛋白和肾脏病理损伤之间的关系。方法根据凝血功能结果,将349例IgAV患儿分为高凝组(52例)和非高凝组(297例),比较两组间尿蛋白和肾脏病理特征,并分析IgAVN患儿高凝状态形成的影响因素。结果高凝组患儿尿红细胞计数、24 h尿蛋白定量、尿蛋白/肌酐、尿免疫球蛋白G/肌酐、尿N-乙酰β-D-氨基葡萄糖苷酶水平高于非高凝组(P<0.05);高凝组患儿肾脏病理分级为Ⅲ~Ⅳ级、弥漫性系膜增生、毛细血管内皮细胞增生、肾小球新月体形成>25%比例高于非高凝组(P<0.05)。多因素logistic回归分析结果显示,毛细血管内皮细胞增生、肾小球新月体形成>25%是IgAVN患儿高凝状态形成的影响因素(P<0.05)。结论伴高凝状态IgAVN患儿的肾损伤更为严重,肾小球新月体形成>25%和毛细血管内皮细胞增生是进一步加重IgAVN高凝状态的重要因素。展开更多
免疫球蛋白A血管炎(IgAV)是一种白细胞碎裂性免疫复合体介导的小血管炎,可导致多脏器受累。急性期可能出现严重的胃肠道出血、肠套叠或穿孔等并发症甚至危及生命。现就IgAV的病因、机制、危险因素、治疗的研究进展进行综述,旨在早期识别...免疫球蛋白A血管炎(IgAV)是一种白细胞碎裂性免疫复合体介导的小血管炎,可导致多脏器受累。急性期可能出现严重的胃肠道出血、肠套叠或穿孔等并发症甚至危及生命。现就IgAV的病因、机制、危险因素、治疗的研究进展进行综述,旨在早期识别IgAV患儿,避免进展为重症病例,有利于临床有针对性的早期预防和治疗。Immunoglobulin A vasculitis (IgAV) is a small vasculitis mediated by leukocyte fragmentation immune complex, which can lead to multiple organ involvement. Severe gastrointestinal bleeding, intussusception, perforation and other complications may occur in the acute stage, even life-threatening. This article reviews the etiology, mechanism, risk factors and treatment of IgAV, aiming at early identification of children with IgAV and avoiding progression to severe cases, which is conducive to targeted early prevention and treatment.展开更多
