摘要:

目的 探讨抗中性粒细胞胞浆抗体(ANCA)检测对系统性血管炎的临床意义。方法 应用间接免疫荧光法(IIF)检测13 866例患者血清ANCA,采用酶联免疫吸附试验(ELISA)检测抗髓过氧化物酶(MPO)抗体和抗蛋白酶3(PR3)抗体。结果 13 866例患者共检出ANCA阳性318例,阳性率为2.29%。其中男性患者检出135例(2.07%)、女性患者检出183例(2.50%),2个组差异无统计学意义(χ2=2.650,P>0.05)。不同年龄组患者间ANCA阳性率差异有统计学意义(χ2=28.978,P<0.01),且男、女性患者各自不同年龄组间ANCA阳性率差异亦有统计学意义(χ2=54.550,P<0.01;χ2=17.800,P<0.01)。p-ANCA和c-ANCA 2种荧光核型及靶抗原分布差异有统计学意义(χ2=86.524,P<0.01)。结论 ANCA的检测对血管炎及自身免疫性疾病的诊断和治疗极为重要,临床工作者应注重ANCA在系统性血管炎及自身免疫性疾病中的检测。

Abstract:

Objective To evaluate the role of anti-neutrophil cytoplasmic antibody(ANCA) determination for systemic vasculitis. Methods Indirect immunofluorescence(IIF) was performed to determine serum ANCA in 13 866 patients,and enzyme-linked immunosorbent assay(ELISA) was used to determine anti-myeloperoxidase(MPO) antibody and anti-protease 3(PR3) antibody. Results Among the 13 866 patients,there were 318 positive cases of ANCA,with the positive rate of 2.29%. There were 135(2.07%) males and 183(2.50%) females,and there was no statistical significance between the 2 groups(χ2=2.650,P>0.05). The difference of the ANCA positive rate with different ages had statistical significance(χ2=28.978,P<0.01). The positive rate of ANCA between males and females in different age groups had statistical significance(χ2=54.550,P<0.01;χ2=17.800,P<0.01). The p-ANCA and c-ANCA and target antigen distribution had statistical significance(χ2=86.524,P<0.01). Conclusions ANCA is potential in the diagnosis and treatment of vasculitis and autoimmune diseases,especially for ANCA-associated systemic vasculitis.
