[摘要] 目的 探究分析抗环瓜氨酸肽(CCP)抗体检测及类风湿因子(RF)定量检测对类风湿关节炎(RA)的诊断特异性和敏感度,以期为类风湿关节炎的临床早期诊断提供借鉴价值。方法 随机选取吉林省公安边防总队医院2015年5月―2017年5月期间收治的57例类风湿关节炎患者以及55例非类风湿性自身免疫性疾病患者作为研究对象,同期选择到院进行健康体检的健康者55名作为对照组,采用ELISA法检测各组患者血清抗CCP抗体,同时采用免疫比浊法检测RA,对比分析各组抗CCP与RA检测结果差异。结果 RA组患者血清抗CCP抗体检测阳性率(87.72%)明显高于非RA组(9.09%)和对照组(0.00%),RA组患者血清RF检测阳性率(80.70%)显著高于非RA组(30.90%)和对照组(7.27%),血清抗CCP抗体联合血清RF检测的敏感度为72.35%,血清抗CCP抗体联合血清RF检测的特异度98.05%明显高于其他两组检测方案,组间比较差异有统计学意义(P /6/view-10743210.htm

[Abstract] Objective This paper tries to explore the anti cyclic citrullinated peptide (CCP) antibody and rheumatoid factor (RF) quantitative detection of rheumatoid arthritis (RA) diagnostic sensitivity and specificity, so as to provide reference for the clinical value of early diagnosis of rheumatoid arthritis. Methods 57 cases of rheumatoid arthritis patients treated from May 2015 to May 2017 in this hospital and 55 cases of non rheumatoid autoimmune disease patients were selected as the research objects, and 55 cases of health examination during the same period in the hospital were selected as the control group, the serum anti CCP antibody was detected by ELISA method, at the same time RA was detected by immune turbidity method, the anti-CCP and RA were compared between the groups. Results The positive rate of serum anti-CCP antibody in RA group was 87.72%, significantly higher than that in non RA group of 9.09% and the control group of 0.00%, the positive rate of serum RF in RA group was 80.70%, significantly higher than that in non RA group of 30.90% and the control group of 7.27%, serum anti CCP antibody combined with serum RF detection sensitivity was 72.35%, serum anti CCP antibody combined detection of serum RF specificity was 98.05%, significantly higher than that of the other two groups of detection scheme, and the difference between groups was statistically significant(P 1 资料与方法
1.1 一般资料
随机选取57例RA患者为到院接收治疗的类风湿关节炎患者,均符合1987年美国风湿病学会修订的RA分类标准[4],疾病活动性采用DAS28评分系统,评分>2.4分为活动性RA[5],并排除使用糖皮质激素和吸烟及其他心血管病危险因素者。RA组患者中女性32例,男性25例,年龄25~76岁,平均(54.7±11.8)岁。非类风湿自身免疫性疾病患者55例作为非RA组,其中男性患者30例,女性患者25例,年龄27~74岁,平均年龄(55.2±10.3)岁,包括强直性脊柱炎27例、系统性红斑狼疮16例、银屑病关节炎7例以及骨关节炎5例。同期选取来院进行健康体检55名作为对照组,其中男性22名,女性患者23名,年龄25~70岁,平均年龄(53.4±10.5)岁。各组基本资料比较差异无统计学意义(P>0.05),具有可比性。
1.2 方法
于第2天抽取患者晨起空腹静脉血各3 mL,放置于洁净试管中,采用离心机分离处理后留取血清备用。采用ELISA法检测患者的抗CCP抗体,检测仪器及配套试剂盒均由德国欧盟公司提供,检测步骤严格按照试剂盒说明书进行。采用免疫比浊法检测RF,检测仪器及配套试剂盒由美国贝克曼库尔特公司提供,检测步骤严格按照试剂盒进行,其中抗CCP>25 RU/ml为阳性,RF>20 IU/mL为阳性。
1.3 统计方法
采用SPSS 18.0统计学软件处理数据,血清抗CCP抗体和血清RF检测阳性率采用(%)表示,行χ2检验,P参考文献]
