2325例患者抗核抗体核型与抗核抗体谱检测结果分析

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%,P0.05),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。

Analysis of anti-nuclear antibody and anti-nuclear antibody spectrum in 2 325 patients

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.816 cases(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.
