J Rheumatol:抗CCP3.1和抗CCP-IgA与无类风湿性关节炎个体的年龄增加相关

2019-04-26 xiangting MedSci原创

在解释抗CCP3.1阳性时,应考虑到无RA个体年龄的增加。

这项研究探讨了在无类风湿性关节炎(RA)的受试者中,年龄与抗环瓜氨酸肽(CCP)抗体的相关性。

研究人员检测了678名RA患者直系亲属(FDRs)和330名骨关节炎(OA)患者血清中的抗CCP3.1(IgG/IgA)。还检测了所有FDRs的同种型(抗CCP-IgA和抗CCP-IgG)。

在FDRs中,年龄增加与抗CCP3.1(每1年,OR=1.03)和抗CCP-IgA阳性(每1年,OR=1.05)显著相关,但与抗CCP-IgG无关。在FDRs和OA受试者中,抗CCP3.1的患病率在50岁后明显增高。

在解释抗CCP3.1阳性时,应考虑到无RA个体年龄的增加。
