摘要:

目的 比较研究间接免疫荧光试验(IFA)、酶联免疫吸附试验(ELISA)和蛋白免疫印迹试验(WB)3种检测方法对莱姆病血清学的诊断效果。方法 收集临床疑似莱姆病患者血清标本及其流行病学和临床资料,分别采用IFA、ELISA和WB进行血清抗伯氏疏螺旋体抗体(IgM和IgG)检测,结合流行病学和临床资料进行综合分析。结果 实验共检测莱姆病疑似患者血清398份,ELISA阳性86例,阳性率21.61%,其中IgM阳性27例,IgG阳性59例;IFA阳性82例,阳性率20.60%,其中IgM阳性26例,IgG阳性56例;WB阳性83例,阳性率20.85%,其中IgM阳性31例,IgG阳性52例;并且实验表明,在对于游走性红斑病例的诊断上,WB法阳性率明显高于ELISA和IFA(χ2=6.34,P<0.05)。结论 在莱姆病的实验室诊断中,IFA、ELISA和WB 3种方法结合运用,可提高诊断的灵敏性和特异性; WB在排除ELISA和IFA的假阳性结果中有着重要作用。

Abstract:

Objective  To compare the effectiveness of indirect immunfluorescence assay (IFA), enzyme-linked immunosorbent assay (ELISA) and western blot (WB) in serologic diagnosis of Lyme disease. Methods Serum samples, epidemiological data and clinical information of potential Lyme disease patients were collected. Serum antibodies (IgM, IgG) against Borrelia burgdorferi were detected by IFA, ELISA and WB. Results were interpreted based on clinical manifestations and epidemiological data. Results Of the 398 serum samples collected from suspected patients, 86 were ELISA-positive (21.61%), including 27 IgM positives and 59 IgG positives; 82 were IFA-positive (20.60%), including 26 IgM positives and 56 IgG positives; and 83 were WB-positive (20.85%), including 31 IgM positives and 52 IgG positives. The positive rate of WB for the diagnosis of patients with erythema migrans (EM) was significantly higher than that of ELISA and IFA (χ2=6.34, P<0.05). Conclusion The combination of IFA, ELISA and WB may improve the sensitivity and specificity of the laboratory diagnosis of Lyme disease. WB has a lower false positive rate than ELISA and IFA.
