Ann Rheum Dis:RA患者心血管疾病风险预测:改良算法并无优势

2015-02-21 梁怀彬 译 MedSci原创

目前对于类风湿关节炎(RA)患者的心血管疾病(CVD)风险预测计算方法仍很不完善,对这类人群的风险评估需要采取特异性的心血管疾病风险预测方法。研究者根据RA患者的特异性心血管风险决定因素对“冠脉疾病风险系统评估方法”(the Systematic COronary Risk Evaluation ,SCORE)进行改良,并评估改良后的SCORE评分对CVD预测的准确性。 主要观察终点是首次CVD发

目前对于类风湿关节炎(RA)患者的心血管疾病(CVD)风险预测计算方法仍很不完善,对这类人群的风险评估需要采取特异性的心血管疾病风险预测方法。研究者根据RA患者的特异性心血管风险决定因素对“冠脉疾病风险系统评估方法”(the Systematic COronary Risk Evaluation ,SCORE)进行改良,并评估改良后的SCORE评分对CVD预测的准确性。 主要观察终点是首次CVD发生,重新校准后的SCORE算法通过对传统的CVD风险因素进行重新加权得到,改良后的SCORE算法的改良之处在于添加进了一些新的潜在预测因素,研究者对经过校准后SCORE算法和改良后SCORE算法效能进行了评估。 收集的1016名RA患者中103人随后发生了CVD,重新校准后SCORE算法和改良后的SCORE算法和原算法相比对CVD的预测识别率相当。Hosmer–Lemeshow 测试结果显示三种算法都对Nijmegen队列和其他RA队列有着较差的一致性。改良后的SCORE算法提高了无CVD事件发生人群中的CVD风险估计值,但是在将来会发生CVD事件的人群中未显示出预测和相应的识别能力。 本研究

Arthritis Care Res:RA早期手骨密度下降可预测侵蚀风险增高

尽管改变病情抗风湿药(DMARDs)的联用使类风湿性关节炎(RA)得到了更好的控制,但仍有一些患者出现进展性侵蚀性病变。早期治疗对患者预后有着积极的意义,研究表明,在“窗口”期对RA进行早期强化治疗可获得良好结局,能减少患者侵蚀性病变及继发残疾的发生。此外,在极早期(前12周)进行RA治疗是12个月时无侵蚀性进展的最好预测指标。对有进展性关节损伤风险的患者做到早期诊断,可让他们提前接受包括生物制剂
