摘要:

目的 用聚类法分析不同类别抗核抗体(ANA)斑点型阳性者间的差异。方法 收集164例ANA斑点型阳性者的血清标本,采用间接免疫荧光法(IIF)和免疫印迹法检测ANA和ANA谱,同时检测其抗环瓜氨酸肽(CCP)抗体、肝功能、肾功能、类风湿因子(RF)、免疫球蛋白、补体和血常规指标。结果 164例ANA斑点型阳性者用聚类法分类并检验后最终分为3类:A类(120例)以抗SS-A、抗Ro-52、抗SS-B的高阳性率为特性,B类(21例)以抗U1-RNP的高阳性率为特征,C类(23例)以抗Sm、抗核糖体P蛋白、抗双链DNA(ds-DNA)、抗核小体、抗组蛋白的高阳性率为特征。B类患者的抗CCP抗体阳性率高于A类和C类患者(P<0.01)。C类患者的肌酐(Cr)、免疫球蛋白(IgG)、球蛋白(GLB)高于A类和B类患者,而白细胞(WBC)则低于A类和B类患者(P<0.01)。结论 对ANA斑点型阳性者进行血清ANA谱聚类分析有助于临床提高自身免疫性疾病(AID)的检出率并及时给予对症治疗。

Abstract:

Objective To analyze the difference of anti-nuclear antibody (ANA) in subjects with nuclear speckled pattern by cluster analysis. Methods Serum samples were collected from 164 subjects with nuclear speckled pattern. Indirect immunofluorescence (IIF) and immunoblotting were used to determine ANA and ANA profile. Anti-cyclic citrullinated peptide (CCP)antibody,liver function,renal function,rheumatoid factor (RF),immunoglobulin,complement and routine blood test indicators were determined. Results The 164 subjects with nuclear speckled pattern were classified,and 3 clusters were identified by cluster analysis. Cluster A (120 cases) was characterized by high positive rates of antibodies against SS-A,Ro-52 and SS-B. Cluster B (21 cases) was characterized by a high positive rate of antibody against U1-RNP. Cluster C (23 cases) was characterized by high positive rates of antibodies against Sm,ribosome P protein, double-stranded DNA(ds-DNA), nucleosome and histone. The positive rate of anti-CCP antibody of Cluster B was higher than those of Cluster A and Cluster C (P<0.01). Cluster C had higher levels of creatinine(Cr),immunoglobulin G (IgG) and globulin (GLB),and Cluster C had lower level of white blood cell (WBC) than those of Cluster A and Cluster B (P<0.01). Conclusions The study on cluster patterns of serum ANA profile in nuclear speckled pattern positive subjects is helpful for improving the determination rate of autoimmune diseases(AID) and timely-symptomatic treatment.
