J Rheumatol:幼年皮肌炎改良疾病活动评分与经验证原始疾病活动评分的相关性

2020-03-30 xiangting MedSci原创

如果来自该数据集的回归方程在将来的数据集中得到成功验证,那么将促进收集儿童JDM疾病活动性相关不同数据中心间的进一步合作。

幼年皮肌炎(JDM)是一种可以治疗的儿童罕见病,但患者可能会受到该病的长期影响。需要进行临床试验以找到更好的治疗方法。临床上用于评估疾病活动性的经验证工具是疾病活动评分(DAS),但并非所有诊所都常规收集该指标。这里开发了一种改良的DAS(DAS mod),该指标可以使用临床工作人员常规收集的数据进行评分,并且已被用于既往研究中。这项研究目的是确定在JDM患者中,DASmod是否与经验证的DAS相关。

在这项研究中,对JDM患者使用DASmod(得分0-12)和DAS评分(得分0-20)。分析了DASmod与经验证的DAS之间的相关性。

在作者JDM诊所就诊的51例患者中,DASmod评分的中位数(IQR)为2.0(0,4.0),DAS评分中位数(IQR)为3.0(0,5.5)。两种工具的评分呈高度正相关(r=0.94,p<0.001,95%CI [0.89,0.96])。线性回归显著(R2=0.88,F(1,49)=357.60,p<0.001),在此数据集中,该工具可与回归方程式互换使用:DAS得分=-0.26+1.5*DAS mod。

如果来自该数据集的回归方程在将来的数据集中得到成功验证,那么将促进收集儿童JDM疾病活动性相关不同数据中心间的进一步合作。

JASN:供体特异性抗体对肾移植结果有负面影响

     目前关于敏感固相试验(SPAs)检测到的低定量供体特异性抗体(DSAs)对肾移植结果的影响仍然不清楚。来自哥伦比亚大学的研究者进行系统回顾和meta分析后发现,移植排异患者SPA显现出了阳性结果,而补体依赖性细胞毒和流式细胞术试验却是阴性结果。   研究者运用了7个回顾性队列研究,包括1119名患者,其中145位具有独立的DSA-SPA。尽管流式细胞术试验
