摘要:

目的 通过系统评价分析支气管肺泡灌洗液(BALF)半乳甘露聚糖(GM)检测对侵袭性肺曲霉病(IPA)的诊断准确性并确定最佳诊断界值。方法 检索Pubmed、EMBASE、OVID、Cochrane Library、中国知网(CNKI)、万方、中国生物医学(CBM)等数据库,自建库至2018年10月31日的相关数据,不限制语言,纳入符合标准的26个研究(71组数据),对其进行质量评价、异质性分析,然后分析计算每个诊断界值的合并指标,绘制受试者工作特征曲线,最终确定最佳诊断界值。结果 BALF-GM(诊断界值为0.5时)诊断IPA(确诊和临床诊断IPA)的合并灵敏度为0.87(95% CI 0.84~0.89),合并特异度为0.79(95% CI 0.77~0.81),合并阳性似然比为4.60(95% CI 3.49~6.05),合并阴性似然比为0.19(95% CI 0.14~0.25),合并诊断比值比为38.84(95% CI 22.99~52.81),集成受试者工作特征(SROC)曲线下面积(AUC)为0.92(95% CI 0.90~0.95)。在BALF-GM诊断界值为1.0时,受试者工作特征(ROC)曲线下面积(AUC)最大为0.94(95% CI 0.93~0.97)。结论 BALF-GM易于检测,对IPA的诊断准确性高,可以对IPA进行早期诊断,早期治疗,降低病死率,目前建议BALF-GM最佳诊断界值为1.0。

Abstract:

Objective To evaluate the diagnostic accuracy of bronchoalveolar lavage fluid (BALF) galactomannan (GM) for invasive pulmonary aspergillosis (IPA) and determine the optimal cut-off value by meta-analysis. Methods The Pubmed, EMBASE, OVID, Cochrane Library, CNKI(China National Knowledge Infrastructure),WANFANG,CBM(China Biology Medicine) databases were searched for relevant studies published in all languages up until October 31, 2018. Twenty-six studies (71 sets of data) meeting the criteria were included in this meta-analysis, conducted quality evaluation and heterogeneity analysis. Then, the pooled indicators of each diagnostic cut-off value, drew the receiver operating characteristic (ROC) curve were analyzed and calculated, and finally the optimal diagnostic cut-off was determined. Results The summary estimates of pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio and diagnostic odds ratio of the BALF-GM (cut-off value 0.5) for the diagnosis of IPA (proven and probable IPA) were 0.87 (95% CI 0.84-0.89), 0.79 (95% CI 0.77-0.81), 4.60 (95% CI 3.49-6.05), 0.19 (95% CI 0.14-0.25), 38.84 (95% CI 22.99-52.81).The area under the curve (AUC) of the summary receiver operating characteristics (SROC) was 0.92 (95% CI 0.90-0.95). When the BALF-GM diagnostic cutoff value in 1.0, the area under curve(AUC) of the summary receiver operating characteristic (SROC) was a maximum of 0.94 (95% CI 0.93-0.97). Conclusions BALF GM was easy to detect and had high diagnostic accuracy for IPA. It could be used for diagnosis of IPA early, so as to implement early treatment and reduce mortality. At present, the recommended diagnostic cut-off was 1.0.
