J Rheumatol:狼疮性肾炎的晚期慢性肾脏病

2020-04-12 xiangting MedSci原创

LN相关性晚期CKD并非必须要进行透析,因为平均10年的随访中62%的患者没有进展。

晚期慢性肾脏病(CKD)使患者进展为终末期肾病(ESRD)的风险升高。这项研究旨在确定狼疮性肾炎(LN)进展为ESRD的比例和主导肾功能下降的因素。

从一个长期纵向队列中确定晚期LN相关性CKD患者。晚期CKD定义为3b期(eGFR=30-44ml/min/1.73m2)和4期(eGFR=15-29ml/min/1.73m2)。对所有个体进行随访,直到进展为ESRD或最后一次问诊,将患者分为“进展者”和“非进展者”。在基线时比较人口学、临床、免疫学和治疗指标。进行了多因素Cox回归分析(时间依赖性和非依赖性)以确定进展的预测因子。

共纳入118名患者(74 名CKD 3b和44 名CKD 4)。平均6年后,有45名患者进展(29名进展为ESRD,16名从CKD 3b进展为CKD 4)。平均10年后,73名患者(“非进展者”)未观察到肾功能明显下降。CKD诊断时的血清学活跃(抗dsDNA滴度高和补体C3/C4低)和基线后每日泼尼松剂量的增加均与进展密切相关。肾素血管紧张素系统(RAS)阻滞剂治疗与进展风险降低相关。

LN相关性晚期CKD并非必须要进行透析,因为平均10年的随访中62%的患者没有进展。确定了某些影响进展为ESRD的预测因素。
