Abstract

Background: This study aimed to evaluate the associations between genetic polymorphisms within target genes and clinical response to methotrexate (MTX) in Chinese rheumatoid arthritis (RA) patients.

Methods: One hundred and fifteen RA patients treated with MTX for approximately 3 months were enrolled, and clinical response was determined by European League Against Rheumatism (EULAR) response criteria and disease activity score in 28 joint counts - erythrocyte sedimentation rate (DAS28-ESR) low disease activity (LDA). Thirty genetic polymorphisms within DHFR, TYMS, ATIC, ADA, and AMPD1 were genotyped.

Results: The major allele of ATIC rs2372536 (RR = 0.85, 95% CI = 0.72 - 0.99, p = 0.04), ATIC rs4673991 (RR = 0.85, 95% CI = 0.73 - 0.99, p = 0.04), ATIC rs4673993 (RR = 0.85, 95% CI = 0.73 - 0.99, p = 0.04), ADA rs2057638 (RR = 0.86, 95% CI = 0.76 - 0.99, p = 0.03), and ADA rs6017375 (RR = 0.86, 95% CI = 0.76 - 0.99, p = 0.03) were found to be significantly associated with EULAR response under dominant model, while the major allele of ADA rs371927 (RR = 1.23, 95% CI = 1.04 - 1.46, p = 0.02) was shown to be significantly associated with EULAR re¬sponse under recessive model. Moreover, the major allele of ADA rs1799880 (RR = 0.60, 95% CI = 0.43 - 0.84, p = 0.003) and rs6031697 (RR = 0.61, 95% CI = 0.47 - 0.78, p < 0.001) were detected to be significantly associated with DAS28-ESR LDA.

Conclusions: Genetic polymorphisms within ATIC and ADA were significantly associated with clinical response to MTX in Chinese patients with RA.

中国类风湿关节炎患者靶基因多态性及甲氨蝶呤的临床反应

背景：本研究旨在评估中国类风湿关节炎（RA）患者靶基因遗传多态性与甲氨蝶呤（MTX）临床反应之间的关系。方法：纳入115例接受MTX治疗约3个月的RA患者，临床反应由欧洲抗风湿病联盟（EULAR）反应标准和28个关节计数-红细胞沉降率（DAS28-ESR）低疾病活动性（LDA）的疾病活动性评分来确定。对DHFR、TYMS、ATIC、ADA和AMPD1的30个遗传多态性进行基因分型。结果:ATIC的主要基因rs2372536 (RR = 0.85, 95% CI = 0.72 - 0.99, p = 0.04), ATIC rs4673991 (RR = 0.85, 95% CI = 0.73 - 0.99, p = 0.04), ATIC rs4673993 (RR = 0.85, 95% CI = 0.73 - 0.99, p = 0.04), ADA rs2057638 (RR = 0.86, 95% CI = 0.76 - 0.99, p = 0.03),和ADA rs6017375 (RR = 0.86, 95% CI = 0.76 - 0.99, p = 0.03)被发现与欧拉响应在主导模式显著相关,而主要的ADA rs371927等位基因(RR = 1.23, 95% CI = 1.04 - 1.46,p = 0.02)在隐性模型下与EULAR反应显著相关。此外，检测到ADA的主要等位基因rs1799880 （RR = 0.60, 95% CI = 0.43 ~ 0.84, p = 0.003）和rs6031697 （RR = 0.61, 95% CI = 0.47 ~ 0.78, p < 0.001）与DAS28-ESR LDA显著相关。结论：ATIC和ADA基因多态性与中国RA患者MTX的临床反应显著相关。
