摘要
目的调查原发性干燥综合征患者抗环瓜氨酸肽[anti-cyclic citrullinated peptide(anti—CCP),抗CCP]抗体阳性率。方法134例原发性干燥综合征患者入选,符合2002年修订的干燥综合征国际分类标准。抗CCP抗体和类风湿因子(RF)分别采用酶联免疫吸附试验(ELISA)和散射速率比浊法测定。结果134例原发性干燥综合征患者,病程(11.1±6.6)年。80例类风湿因子(RF)阳性(59.7%),10例抗CCP抗体阳性,阳性率为7.46%(3.01%~11.91%)。抗CCP抗体阳性和抗CCP抗体阴性患者在临床和实验室指标方面差异无显著性。结论大多数原发性干燥综合征患者抗CCP抗体阴性,但是阳性检测结果不能排除原发性干燥综合征的诊断。抗CCP抗体阳性患者有可能发展为类风湿关节炎,需要密切的临床和放射学随访。
Objectives To investigate the prevalence of anti-cyclic eitrullinated peptide (anti-CCP) antibodies in patients with primary Sjogren's syndrome Methods 134 patients with primary Sjogren's syndrome were recruited. Anti-CCP antibody and rheumatoid factor (RF) were evaluated with enzyme linked immunosorbent assay kits and standard nephelometry methods, respectively. Results Of 134 patients, 80 eases(59%) were positive for rheumatoid factor (RF) and 10 cases (7.5 %) for anti-CCP. There was no difference in clinical and biological features between anti- CCP positive and negative patients. Conclusions Most patients with primary Sjogren's syndrome are negative in anti- CCP, but patients with positive results should not be rule out diagnosis for primary Sjogren's syndrome.
