Arthritis Rheumatol:建立狼疮性肾炎临床试验的肾脏替代终点

2018-09-21 xiangting MedSci原创

来自短期肾脏治疗反应的HITs与长期肾脏预后相关。

目前狼疮性肾炎(LN)临床试验的终点缺乏统一性,并且反映的长期肾脏生存率不确定。这项调查目的是确定用于临床试验能够预测长期肾脏结局的短期终点。

从3个临床试验和12个纵向队列收集了944名LN患者的数据。将诊断为活动性LN(预测期)后头12个月治疗的变量作为36个月随访期长期预后的潜在预测因子进行评估。长期预后是新的或进展性慢性肾病(CKD)、严重肾损伤(SKI)和需要永久肾替代疗法(RRT)。使用Cox比例风险回归的多因素分析推导出用于预测每种预后风险的危险指数工具(HIT)。

550例符合条件的受试者中,有54例CKD、55例SKI和22例RRT事件。最终CKD HIT中的变量是预测期CKD状态、12个月蛋白尿和12个月血清肌酐(SCr)。SKI HIT包括预测期CKD状态、ISN分级、12个月蛋白尿、12个月SCr、种族以及ISN分级和12个月蛋白尿之间的相互作用。RRT HIT包括诊断年龄、12个月蛋白尿和12个月SCr。每个HIT在内部(c-指数0.84-0.92)和独立LN队列验证良好(c-指数0.83-0.92)。

来自短期肾脏治疗反应的HITs与长期肾脏预后相关,现在必须作为LN临床试验的替代终点进行验证。
