摘要
目的 探讨支气管肺泡灌洗液(bronchoalveolar lavage fluid,BALF)半乳甘露聚糖(galactomannan,GM)检测在非中性粒细胞缺乏患者侵袭性肺曲霉病(invasive pulmonary aspergillosis,IPA)诊断中的价值.方法 回顾性分析2014年1月至2021年12月住院并符合纳入标准的788例患者,根据EORTC/MSG诊断标准和专家共识,分为确诊IPA、临床诊断IPA、拟诊IPA和非IPA组,用统计学方法对BALF GM检测结果进行分析,比较不同阈值时BALF GM检测的灵敏度、特异性、约登指数.结果 4例确诊IPA、156例临床诊断IPA为病例组,非IPA 160例为对照组.对于BALF GM检测,ROC曲线分析当cut-off≥0.935时,约登指数为0.969,是最佳的界值点,灵敏度为98.8％,特异性为98.1％.当cut-off≥1.51时,灵敏度为78.8％,特异性为100.0％.结论 BALF GM检测在非中性粒细胞缺乏患者IPA诊断中具有重要意义.
Abstract
Objective To explore the value of galactomannan testing of bronchoalveolar lavage fluid for the diagnosis of invasive pulmonary aspergillosis in non-neutropenic patients.Methods A retrospective analysis was conducted in 788 patients admitted to the hospital between January,2014 and December,2021.We then determined an optimal BALF galactomannan OD cut-off value for IPA in at-risk patients.Results There were a total of 160 cases (4 proven and 156 probable IPA)and 160 controls in this study.ROC curve demonstrated an optimum OD index cut-off of 0.935,with a high specificity(98.1％)and sensitivity (98.8％)for diagnosing IPA.With a cut-off ≥1.51,BALF galactomannan sensitivity and specificity for diagnosing IPA were 78.8％ and 100.0％,respectively.Conclusion Our study demonstrates that BALF galactomannan testing can be a safe and useful adjunct for the diagnosis of IPA in non-neutropenic patients.
