摘要 目的:研究抗环瓜氨酸肽(cyclic citrullinated peptide,CCP)在类风湿性关节炎(rheumatoid arthritis,RA)诊断中的临床应用。方法:以确诊的类风湿关节炎(RA)患者50例为研究对象,其它结缔组织疾病(connec tivetissue disease,CTD)患者50例作为对照,测定血清抗CCP抗体及类风湿因子(rheumatoid factor,RF)水平,观察抗CCP抗体诊断RA的敏感度、特异度、阳性预测值、阴性预测值。结果:抗CCP抗体在RA组阳性率最高;诊断RA,抗CCP抗体的敏感度和特异度、阳性预测值、阴性预测值:为74.0%、97.0%、92.5%、88.2%;RF为86.0%、58.0%、50.6%、89.2%。结论:抗CCP抗体诊断RA有较高的特异度,可用于RA的诊断与鉴别诊断。
