摘要
目的为探讨抗ds—DNA抗体、抗ENA多肽抗体联合检测在系统性红斑狼疮(SLE)诊断中的应用。方法应用抗ds—DNA抗体(间接免疫荧光法IIF)、抗ENA多肽抗体试剂盒(免疫印迹法IBT)分别检测抗ds—DNA抗体及抗ENA多肽抗体谱。结果156例SLE患者中共检出抗ds—DNA抗体阳性98例(62.8%),抗ENA多肽抗体阳性112例(71.8%),SLE患者组抗ds—DNA抗体及抗ENA多肽抗体指标均高于正常对照组(P〈0.01)。结论抗ds—DNA抗体及抗ENA多肽抗体在SLE诊断中具有互补作用,并能提高对SLE诊断符合率,在观察治疗及预后中具有重要的临床价值。
Objective To investigate the application of collective determination of anti - ds - DNA and anti - ENA polypeptide antibody in diagnosis of SLE patients. Methods To test anti - ds DNA by indirect immunoflorescence while to test ENA polypeptide antibody by immunolabelling technique(IBT). Results In 156 cases SLE test. anti - ds - DNA postitive rate was 62. 8% (98 cases) and anti - ENA polypeptide antibody positive rate was 71.8% (112 cases). It was showed that positive rates of anti -ds -DNA and anti -ENA polypeptide antibody were significantly higher in SLE patients than those in normal controls. Conclusions In diagnosing SLE, collective determination of anti - ds DNA and anti - ENA polypetide antibody can complement each other upgrade the detectable rate and have the significant clinical value in diagnostic classification and prognosis of the diseases.
