J Rheumatol:狼疮性肾炎患者的肾脏缓解状况和长期肾脏存活情况

2018-03-04 xiangting MedSci原创

LN诊断后24个月的肾脏缓解状态是长期肾脏存活的重要预测指标。

这项观察性研究是对前瞻性收集的Hopkins狼疮队列数据进行回顾性分析,以比较标准诱导治疗后狼疮肾炎(LN)达到完全缓解(CR)、部分缓解(PR)或无缓解的LN患者的长期存活情况。

查找对经活检证实的LN患者(修订的美国风湿病学会或系统性狼疮协作诊断标准),并在诊断后24个月将其分为按顺序的(CR,PR,或无缓解)或二分类(缓解或无缓解)的肾缓解类别 [改良的Aspreva狼疮管理研究(mALMS)和修订贝利木单抗国际狼疮肾炎研究(mBLISS-LN)标准]。主要终点是长期肾脏存活情况[无终末期肾病(ESRD)或死亡]。

共有176名患者符合纳入标准。在24个月活检时,符合mALMS缓解标准(CR = 59.1%,PR = 30.1%)的患者比mBLISS-LN标准的更多(CR = 40.9%,PR = 16.5%)。在随后的随访中,18名患者出现ESRD或死亡。Kaplan-Meier曲线提示,使用mALMS(p = 0.0038)和mBLISS-LN(p=0.0097)缓解标准,24个月时无缓解的患者比PR或CR患者出现这种结果的可能性更大。基于调整主要混杂因素的Cox回归模型, mBLISS-LN(HR 0.254,95%CI 0.082-0.787; p = 0.0176)和mALMS标准(HR 0.228,95%CI 0.063-0.828; p = 0.0246)的CR患者发生ESRD /死亡的可能性显著低于未缓解患者。

LN诊断后24个月的肾脏缓解状态是长期肾脏存活的重要预测指标,也是临床相关的终点指标。
