J Rheumatol:增生性狼疮肾炎中新月体对肾脏结局的意义

2018-03-15 xiangting MedSci原创

新月体>25%的增生性狼疮肾炎的短期和长期肾脏预后更差。细胞和纤维细胞新月体比例是肾脏存活率差的独立危险因素。

这项研究旨在确定新月体与肾脏结局之间的关联,以及对治疗方案选择的影响。

将231例活检证实的增生性狼疮肾炎(PLN)患者分为4组:非新月体组(NC组)59例; 仅有节段性新月体59例,为节段性新月体组(SC); 周围新月体根据新月体比例分为2组(C1有64例≤25%,C2有49例> 25%)。比较了患者的基线实验室检查,组织病理学表现和预后。

NC组、SC组、C1组和C2组的缓解率分别为92.1%、85.4%、95.0%和76.1%。C2组患者达到完全缓解的患者较其他三组少。对于通过血清肌酐(SCr)加倍或终末期肾病(ESRD)评估的长期结局,C2组肾存活率最低(p = 0.003)。单独在Cox比例风险回归模型中包括临床和病理变量,多变量分析显示以下指标是SCr加倍或ESRD的独立危险因素:基线SCr(每增加1mg/dl:HR = 1.834,95%CI1.465- 2.296; p <0.001),血红蛋白(每增加1g /l:HR = 0.970,95%CI 0.947-0.992; p = 0.009),细胞新月体的比例(每增加1%:HR = 1.040,95%CI 1.015-1.066; p = 0.002),纤维细胞新月体(每增加1%:HR = 1.085,95%CI 1.013-1.163; p = 0.020)和重度肾小管萎缩(HR = 5.348,95%CI 1.278-22.373; p = 0.022)。

新月体>25%的增生性狼疮肾炎的短期和长期肾脏预后更差。细胞和纤维细胞新月体比例是肾脏存活率差的独立危险因素。
