The aims of this study were to assess the prevalence of US-detected residual synovitis in patients with RA in clinical remission (CR) and evaluate its predictive value for relapse and structural progression.
We performed a systematic literature search of Medline, Embase and rheumatology meeting databases from 1 January 2001 to 28 May 2012. The prevalence of US grey-scale (USGS) signals (synovial hypertrophy or joint effusion) and power Doppler (PD) signals were collected, taking into account CR definitions [44-joint DAS (DAS44), 28-joint DAS (DAS28), SDAI, ACR 1981 or ACR/European League Against Rheumatism 2011], stage of RA (early or long-standing) and US examination (from 5 to 44 joints assessed). A meta-analysis assessing the risk of relapse or structural progression in patients with synovitis involved the Mantel-Haenszel method.
We included 19 studies of 1618 patients, 1369 in remission. The prevalence of USGS positive (USGS+), USGS+/PD negative (PD-), USGS+/PD positive (PD+) and USGS negative (USGS-/PD- was 84%, 41%, 44% and 15%, respectively. The prevalence of USGS+ or USGS+/PD+ was comparable among CR definitions and US methods. The prevalence of USGS+ and USGS+/PD+ was greater for long-standing than early RA (P < 0.001). Meta-analyses of five studies (271 patients), three studies (173 patients) and two studies (798 joints) revealed an association of USGS+/PD+ and risk of relapse [odds ratio (OR) 3.2 (95% CI 1.8, 5.9), P = 0.0001, I(2) = 0%] and structural progression in individual patients [OR 9.13 (95% CI 1.1, 74.3), P = 0.04, I(2) = 43%] and joints [OR 6.95 (95% CI 3.4, 13.9), P < 0.0001, I(2) = 6%] over 1-2 years.
US-detected residual synovitis is frequent and predicts the risk of relapse and structural progression in RA patients with CR.
本研究旨在评估临床缓解（CR）的类风湿关节炎（RA）患者中超声检测到的残余滑膜炎的患病率，并评估其对复发和结构进展的预测价值。
我们对2001年1月1日至2012年5月28日期间的Medline、Embase和风湿病会议数据库进行了系统的文献检索。收集了超声灰阶（USGS）信号（滑膜肥厚或关节积液）和能量多普勒（PD）信号的患病率，同时考虑了CR的定义[44关节疾病活动评分（DAS44）、28关节疾病活动评分（DAS28）、简化疾病活动指数（SDAI）、美国风湿病学会1981年标准或美国风湿病学会/欧洲抗风湿病联盟2011年标准]、RA的病程阶段（早期或病程较长）以及超声检查（评估5至44个关节）。一项评估滑膜炎患者复发或结构进展风险的荟萃分析采用了Mantel-Haenszel方法。
我们纳入了19项研究，共1618例患者，其中1369例处于缓解期。USGS阳性（USGS+）、USGS+/PD阴性（PD-）、USGS+/PD阳性（PD+）和USGS阴性（USGS-/PD-）的患病率分别为84%、41%、44%和15%。USGS+或USGS+/PD+的患病率在CR定义和超声检查方法之间具有可比性。病程较长的RA患者中USGS+和USGS+/PD+的患病率高于早期患者（P<0.001）。对五项研究（271例患者）、三项研究（173例患者）和两项研究（798个关节）的荟萃分析显示，USGS+/PD+与1至2年内个体患者的复发风险[比值比（OR）3.2（95%可信区间1.8，5.9），P=0.0001，I²=0%]以及结构进展相关[OR 9.13（95%可信区间1.1，74.3），P=0.04，I²=43%]，在关节层面也与结构进展相关[OR 6.95（95%可信区间3.4，13.9），P<0.0001，I²=6%]。
超声检测到的残余滑膜炎很常见，并可预测临床缓解的RA患者的复发风险和结构进展。
