2325例患者抗核抗体核型与抗核抗体谱检测结果分析

Analysis of anti-nuclear antibody and anti-nuclear antibody spectrum in 2325 patients

目的探讨抗核抗体(ANA)核型与抗核抗体谱(ANAs)检测的临床应用价值。方法分别采用间接免疫荧光法(IIF)和线性免疫印迹法(LIA)对2 325例自身免疫性疾病(AID)确诊及疑似患者ANA和ANAs进行检测,分析ANA核型和ANAs检测结果。结果 2 325例患者中,检出ANA阳性896例,阳性率为38.54%,女性患者阳性率(45.46%)高于男性患者(18.46%,P<0.05),常见荧光核型为核颗粒型、核均质型、核仁型;检出ANAs阳性816例,阳性率为35.10%,阳性率较高的分别为抗干燥综合征(SS)-B抗体、抗Ro-52抗体、抗SS-A抗体等。两种方法检测结果一致率为91.66%。结论 IIF法ANA检测结果和LIA法ANAs检测结果具有一定的相关性,但并不完全一致;二者联合检测具有互补性,可提高检出率,避免漏诊。

Objective To investigate the clinical value of anti-nuclear antibody(ANA)and anti-nuclear antibody spectrum(ANAs)detection.Methods A total of 2 325 patients with or suspected with autoimmune diseases(AID)were enrolled and detected for ANA and ANAs by using indirect immunofluorescence assay(IIF)and linear immunoblot assay(LIA)respectively.All detected results were analyzed.Results Among 2 325 patients,896 cases(38.54%)were positive with ANA,with positive rate of 45.46% in female patients,which was higher than the 18.46% of male patients(P<0.05),and the common fluorescence patterns were nuclear particle pattern,nuclear homogeneous pattern and the nucleolus pattern.816cases(35.10%)were positive with ANAs,and the positive rates of anti-Sjogren′s syndrome(SS)-B antibody,anti Ro-52 antibody and anti SS-A antibody were relatively higher.The consistency rate of the two methods was 91.66%.Conclusion ANA and ANAs detection could be with certain correlation,but might be not completely consistent,detection could improve the detection rate and reduce the missed detection rate.
