抗环瓜氨酸肽抗体和类风湿因子联合检测对类风湿关节炎的临床价值

目的探讨抗环瓜氨酸肽(CCP)抗体和类风湿因子(RF)联合检测对类风湿关节炎(RA)诊治的临床价值。方法收集2013年11月至2014年12月该院182例风湿性疾病患者血清,采用ELISA方法检测CCP抗体,使用免疫透射比浊终点法检测RF。结果 (1)182例患者中RA 99例,CCP中位数是4.20,RF是392,非类风湿疾病患者83例,CCP中位数是2.30,RF是20.1,健康对照者106例,CCP中位数是1.23,RF是12.3。健康对照者与非风湿性疾病患者比较,差异无统计学意义(P0.05);与RA患者比较,差异有统计学意义(P0.01)。(2)CCP抗体诊断RA的特异度是90.5%,RF是79.2%,CCP抗体高于RF,差异有统计学意义(P0.05);CCP抗体和RF联合检测诊断RA的灵敏度是71.4%,特异度是96.2%,高于单项检测(P0.01)。CCP抗体和RF的灵敏度比较,差异无统计学意义(P0.05)。CCP抗体特异度高于RF。结论 CCP抗体和RF联合检测有助于RA的诊断和疗效监测,具有较高的临床意义。

Clinical value of combined detection of anti-cyclic citrullinated peptide antibody and rheumatoid factor for rhenmatoid arthritis

Objective To estimate the clinical value of combined detection of anti‐cyclic citrullinated peptide (anti‐ccp)antibody and rheumatoid factor(RF) for the rhenmatoid arthritis .Methods Having collected the serum of 182 patients with rheumatic diseases in our hospital from November 2013 to December 2014 .With ELISA method measuring CCP and use immunity transmission turbidity to measurement RF ,the results were compared and ana‐lyzed .Results (1)Among the serum of 182 cases of patients ,99 cases were with rheumatoid arthritis ,with median of CCP 4 .20 and RF 392 .83 cases were with non‐rheumatoid diseases ,that with median of CCP 2 .30 and RF 20 .1 .106 cases of healthy control were ,with median of CCP 1 .23 and RF 12 .3 .Compared with non‐rheumatoid diseases ,P>0 .05 and the difference was of no statistical significance ;Compared with rheumatic diseases ,P< 0 .01 and the differ‐ence was of statistical significance ;The level of CCP was obviously higher than ordinary patients .(2)The specificity of RA diagnosed by CCP was 90 .5% ,the specificity of RA diagnosed by RF was 79 .2% ,CCP was higher than RF (P< 0 .05) .The sensitivity of RA detected and diagnosed by the combination of CCP and RF was 71 .4% and the specificity was 96 .2% ,which were higher than respective detection and diagnosis(P< 0 .01) .The sensitivity between CCP and RF was of no statistical significance(P> 0 .05) .The specificity of CCP was higher than that of RF .Conclu‐sion The combined detection of anti‐cyclic citrullinated peptide antibody and rhenmatoid factor was conducive to di‐agnosis and monitoring therapy of the RA .
