【摘要】目的: 研究类风湿关节炎(rheumatoid arthritis, RA)患者血清抗环瓜氨酸肽(cyclic citrullinated peptide, CCP)抗体、类风湿因子(rheumatoid factor,RF)和白介素17(interleukin17,IL17)水平变化及临床应用价值。方法: 收集80例RA患者血清,以80例健康体检者血清作对照。P抗体,IL17含量,特种蛋白仪检测RF含量,并进行统计分析。结果: RA患者活动期上述指标的含量均显著高于稳定期和健康对照组(P<0. 01)。RA患者组三项指标的阳性率明显高于正常对照组(P<0. 01)。P抗体及IL17,P抗体对RA的特异性显著高于RF及IL17。两两联合检测及三者联合检测敏感性较单独检测都有所减低,而特异性增高明显,三者联合检测,特异性达到100%。结论: P抗体、RF和IL17有助于观察RA病情变化,提高RA诊断率。

[Abstract] Objective: To explore the clinical significance and the clinical value of changes of serum P antibody, rheumatoid factor(RF) and IL17 levels in patients with rheumatoid arthritis(RA). Methods: Serum P antibody and IL17 was detected in 80 case of RA and 80 case of healthy physical examines by enzyme linked immunosorbent assay(ELISA), Beckman automated protein analysis system was used to detect serum RF. Following, some statistical analysis for these data were done. Results: P antibody, RF and IL17 levels in the acute phase of RA group were significantly higher than those in the stable phase of RA group and the healthy physical examines group (P<0. 01). Three detection items positive rate were apparently higher in RA group than in the healthy physical examines group (P<0. 01). Comparative analysis showed that RF sensitivity was higher than
