-
摘要:
目的 分析类风湿关节炎(rheumatoid arthritis, RA)中干扰素诱导蛋白10(interferon-inducible protein 10, IP-10)表达水平的变化,评估其在RA中的诊断价值及与疾病活动的相关性。 方法 通过电子文献检索,在Cochrane图书馆、Scopus和PubMed数据库(截至2020年9月16日)搜索相关的文献,采用诊断准确性研究的质量评估工具2(quality assessment of diagnostic accuracy studies-2, QUADAS-2)对文献进行评价,并进行定量、综合分析。 结果 最终纳入文献17篇,RA患者IP-10表达水平高于健康对照(healthy control, HC)[标准化均数差(standard mean difference, SMD)=0.93, 95% CI : 0.51~1.35]。此外,IP-10表达水平在RA与骨关节炎(osteoarthritis, OA)中也存在差异(SMD=3.84, 95% CI: 0.76~6.92),但在RA和系统性红斑狼疮(systemic lupus erythematosus, SLE)之间差异无统计学意义。IP-10用于RA诊断的合并诊断比值比(diagnostic odds ratio, DOR)为65.70(95% CI: 1.52~2 844.43),曲线下面积(area under the curve, AUC)为0.889 6。 结论 IP-10表达水平在RA患者与HC和OA患者之间存在差异,可作为潜在的诊断性生物标志物。 Abstract:Objective We aimed to analyze the changes of interferon-inducible protein 10 (IP-10) in rheumatoid arthritis (RA) and evaluate the diagnostic value of IP-10 in RA and its correlation with disease activity. Methods We collected articles related to our research topic through an electronic literature search from the Cochrane Library, Scopus, and Pubmed (up to Sep16th, 2020). Quality assessment of diagnostic accuracy studies (QUADAS-2) tool was used to assess the quality of collected articles, and quantitative and comprehensive analysis was conducted. Results 17 studies were finally included in this study. IP-10 level in RA patients was higher than health controls [pooled standard mean difference (SMD) = 0.93, 95% CI= 0.51-1.35]. Besides, IP-10 levels in RA patients differed from osteoarthritis (OA) controls, with a pooled SMD and 95% CI being 3.84 (0.76-6.92). We found no significant difference in IP-10 levels between RA patients and systemic lupus erythematosus (SLE) controls. The pooled diagnostic odds ratio (DOR) value for IP-10 to diagnose RA was 65.70 (1.52-2 844.43) and AUC value was 0.899 6. Conclusion IP-10 levels differ from RA patients to HC and OA controls, it may be a potential diagnostic biomarker. -
