Abstract

目的 了解儿童系统性红斑狼疮(systemic lupus erythematosus,SLE)临床特点,探讨抗核小体抗体(anti-nucleosome antibodies,AnuA)与SLE临床特点的关系。 方法 回顾性分析2011年4月至2017年4月在江西省儿童医院住院确诊的SLE患儿病历资料。 结果 58例SLE患儿中,29例AnuA阳性与29例AnuA阴性SLE患儿比较,两组间水肿、贫血、肾功能、狼疮性肾炎的病理活动性指数、慢性指数、抗dsDNA抗体阳性率、抗组蛋白抗体阳性率、抗心磷脂抗体阳性率和补体C4下降程度等指标差异均有统计学意义。AnuA阳性SLE患儿肾脏损害程度更重,且病理损害活动度更高,抗dsDNA抗体阳性率、抗组蛋白抗体阳性率、抗心磷脂抗体阳性率更高,补体C4下降程度和贫血程度更重。 结论 AnuA对SLE的诊断具有一定指导意义,并可作为SLE患儿进行肾活检的参考指标之一。
