摘要 目的:分析狼疮肾炎(lupusnephritis,LN)患者肾脏免疫物质沉积强度与病理分型及临床指标的关系。方法:回顾性分析41例狼疮性肾炎患者(均行肾活检)的临床表现、实验室指标和病理资料。结果:41例LN患者均有蛋白尿,临床分型以肾病综合征型最为常见(20/41,48.7%),其次为肾功能不全型12例(29.2%),肾炎综合征型7例(17%),隐匿性肾炎型2例(4.8%)。各免疫物质(IgA,IgG,IgM,C3,C4,C1q)基本呈"满堂亮"沉积,以Ⅴ型(合并Ⅳ型、Ⅲ型)LN的IgG沉积明显,但差异无统计学意义。抗ds-DNA滴度与肾脏穿刺组织中C3的沉积强度呈正相关关系(P<0.05);但SLEDAI评分、24h尿蛋白定量、血肌酐与肾脏免疫物质沉积未见明显相关性。结论:LN患者的临床表现与肾脏病理改变复杂多样,两者有一定的相关性;不同病理类型的LN,其发病机制可能存在差异;肾组织补体C3荧光沉积强度可以作为病情严重及活动的参考指标。
