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

2014-07-31 周泳 丁香园

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

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在内的强化治疗。

RA早期的疾病活动性指标并不能作为12个月时侵蚀损害的预测因子,因此需要在关节损害发生前的疾病早期发掘其他有预测价值的指标。在关节侵蚀出现前,RA最早的影像学改变是关节周围的骨质减少。既往研究表明,RA早期骨密度(BMD)降低与后续的关节损伤相关;尽管在研究中应用数字化x线片测量法(在数字化射线照片的基础上使用专业软件计算掌骨BMD)对BMD进行测量十分有效,但其临床应用尚未成熟。

此项研究使用双能x线吸收法(DXA)测量手BMD,探讨RA确诊后的头6个月内BMD降低能否作为侵蚀改变的早期预测指标。研究由澳大利亚阿德雷德皇家医院Black RJ等进行,结果于2014年4月在《关节炎护理与研究》(Arthritis Care Res (Hoboken))杂志上发布。

研究共纳入106名接受目标治疗的患者,均为早期RA患者,无DMARD治疗史。采用双能x线吸收法测量基线时间和6个月时的手BMD,分别在基线时间和12个月时行手、足射线检查,并使用Sharp/van der Heijde修正评分表进行评分。使用K-均值聚类算法将患者分为两组:根据患者从基线时间到6个月时BMD的绝对变化值,分为BMD降低组和骨密度无降低组。采用多元回归分析(障碍模型)对两组侵蚀性病变发生的风险及其侵蚀分数进行分析。

结果显示,6个月时手BMD降低与12个月时的侵蚀分数相关(P = 0.021)。多元回归分析显示,手BMD降低(P = 0.046)以及发病年龄大(≥50岁,P = 0.014)与侵蚀性病变的发生相关,此外,基线时间的侵蚀评分及抗环瓜氨酸肽水平均与侵蚀严重程度/进程相关。

接受目标治疗的RA患者中,早期手BMD降低提示12个月时侵蚀病变发生的风险更高,这为预防侵袭病变损害的强化治疗提供了研究基础。
