| 目的探讨在非免疫功能低下病人中，支气管肺泡灌洗液( BALF)及血清中半乳甘露聚糖检测( GM试验)对侵袭性肺曲霉病( IPA)的诊断价值，并确定 BALF-GM试验对 IPA的最优截断值。方法选择 2018年 9月至 2022年 10月徐州医科大学附属医院 173例疑为肺部真菌感染的非免疫功能低下病人，分级诊断结果为确诊、临床诊断的人群纳入 IPA组，结果为排除的纳入非 IPA组(对照组)，所有病人均进行血清及 BALF-GM试验，对试验结果进行统计分析，比较其对非免疫功能低下病人 IPA的诊断价值。结果在非免疫功能低下病人中， BALF-GM试验对 IPA的诊断最佳截断值为 0.55，灵敏度及特异度分别为 91.9%、59.5%，曲线下面积( AUC)及其 95%CI为 0.81(0.66，0.86)血清 GM试验对 IPA的诊断最佳截断值为 0.25，灵敏度及特异度分别为 43.2%、90.4%，AUC及其 95%CI为 0.66(0.56，0.77)。在非免疫功能低下病人中， BALF-GM试验对 IPA具有良好的辅结论，助诊断作用，血清 GM试验对非免疫功能低下病人 IPA诊断敏感性较低，诊断作用有限。 |

| Objective To investigate the diagnostic value of galactomannan (GM) test in bronchoalveolar lavage fluid (BALF) and se-rum for immunocompromised patients with invasive pulmonary aspergillosis (IPA), and to determine the best cut-off value of BALF-GM test for IPA.Methods A total of 173 non-immunocompromised patients, who were suspected of pulmonary fungal infection in The Affil-iated Hospital of Xuzhou Medical University from September 2018 to October 2022, were included in the study. Patients with confirmeddiagnostic results and clinical diagnosis were assigned to the IPA group, while the excluded patients were assigned to the non-IPA group. Serum and BALF-GM tests were performed in all patients, and the test results were statistically analyzed and compared for the di-agnostic value of BALF-GM test in non-immunocompromised patients.Results In immunocompromised patients, the best cut-off value of BALF-GM test for IPA was 0.55, the sensitivity and specificity were 91.9% and 59.5% respectively, and the area under the curve(AUC) was 0.81 [95%CI: (0.66, 0.86)]. The best cut-off value of serum GM test for IPA was 0.25, the sensitivity and specificity were sepa-rately 43.2% and 90.4%, and AUC was 0.66 [95%CI: (0.56, 0.77)].Conclusion In immunocompromised patients, BALF-GM test has a good diagnostic effect on IPA, while the diagnostic sensitivity of serum-GM test to IPA is low, whose diagnostic value for IPA is limited. |
