Clinica Chimica Acta:14-3-3η和抗碳胺化蛋白抗体在北方汉族类风湿关节炎中的诊断价值如何?

2020-04-12 MedSci原创 MedSci原创

当类风湿因子(RF)或抗环瓜氨酸肽抗体(anti-CCP)为阴性时,不能排除类风湿关节炎(RA)。

当类风湿因子(RF)或抗环瓜氨酸肽抗体(anti-CCP)为阴性时,不能排除类风湿关节炎(RA)。在此,我们确定了14-3-3η蛋白,抗碳酰化蛋白抗体(anti-CarP)的应用价值,以及它们与RF或抗CCP一起诊断RA的潜在作用。

研究人员检测291例RA患者223例除RA外的自身免疫性疾病,156例从中国北方汉族人群中招募的健康受试者的血清抗CCP、RF、14-3-3η和抗CarP抗体水平。 我们检查了各组之间这些指标水平的差异,并比较了其中任何两个指标之间的相关性。 同时,共建立了12种检测策略进行比较,以最大限度地提高诊断价值。

研究结果显示RA患者的RF、抗CCP、抗CARP和14-3-3-3η的水平明显高于干扰对照组(分别为12.5;[9.36-15.7]、30.7;[25.7-35.6]、1.90;[1.70-2.01]、15.8;[10.8-20.8]),而干扰对照组(1. 24;[1.07-1.41],0.64;[0.42-0.86],0.51;[0.46-0.57],0.33;[0.23-0.44],分别)(P<0.0001)或健康对照组(1. 03;[0.99-1.08],0.49;[0.38-0.59],0.28;[0.21-0.35],0.55;[0.27-0.85],分别为0.33;[0.27-0.85])(P<0.0001)。) 在所有12种检测策略中,任意2种标志物双阳性或抗CCP单阳性均可诊断为RA的新型策略的YI值和κ值最高。

研究结果表明,在中国北方汉族人群中,抗CarP抗体和14-3-3-3η蛋白可作为RA的有价值的指标,尤其是与RF和抗CCP联合使用时,检测价值最大化。
