ELISA检测抗PLA2R抗体对IMN诊断价值的meta分析

摘要

目的 探讨酶联免疫吸附法(ELISA)检测抗磷脂酶A2受体抗体(anti-PLA2R)在特发性膜性肾病的中的诊断价值.方法 检索Medline、PubMed、中国学术期刊全文数据库(CNKI)、万方及维普数据库中2012年1月至2017年4月国内及国外公开发表的ELISA法测anti-PLA2R在特发性膜性肾病的中的诊断价值的相关文献.使用质量评估方法(QUADAS)评价文献质量.根据纳入标准和排除标准选取研究对象并提取数据,通过M eta-Disc1.4软件进行分析.最后得出总的敏感度、特异度及受试者工作曲线(ROC)综合评价ELISA法测anti-PLA2R对IM N的诊断价值.结果 共筛选出10篇文献.累计病例1517例.合并敏感度为0.68[95% CI(0.64,0.70)];合并特异度为0.92[95% CI(0.90,0.95)],ROC曲线显示曲线下面积(AUC)为0.8074.结论 ELISA法检测anti-PLA2R对特发性膜性肾病诊断效能良好,可作为特发性膜性肾病诊断的有效补充指标.%Objective To investigate the diagnostic value of Enzymes linked immunosorbent assay(ELISA)detection of anti phospholipase A2 receptor antibody(anti-PLA2R)in idiopathic membranous nephropathy patients.Methods All articles published from January 2012 to April 2017 about ELISA test on anti phospholipase A2 recepeor antibody as a maker for IMN were collected, and the quality of the studies was evaluated by using the guidelines of the updated Quality Assessment of Diagnostic Accuracy Stud-ies(QUADAS-2)tool.According to the inclusion criteria and exclusion criteria,the research objects were selected and the data were extracted,and the analysis was carried out by Meta-Disc1.4 software.The results are summarized on the basis of sensitivity,speci-ficity,and summary receiver operating characteristic curve(ROC curve).Results Ten articles were selected according to inclusion criteria and 1517 cases were included in the study.The combined sensitivity was 0.68[95% CI(0.64,0.70)];the merge specificity was 0.92[95% CI(0.90,0.95)],and the subjects'working curve showed AUC 0.807 4.Conclusion The detection of anti-PLA2R by ELISA is effective in the diagnosis of idiopathic membranous nephropathy,which can be used as an effective supplement for the diagnosis of idiopathic membranous nephropathy.
