摘要: 目的

比较血清及支气管肺泡灌洗液(bronchoalveolar lavage fluid, BALF)两种不同标本的 GM 试验在侵袭性肺曲霉病( invasive pulmonary aspergillosis, IPA)诊断中的价值。

方法

病例组为济南市第四人民医院呼吸与危重症医学科及其它临床科室诊断及拟诊为 IPA的 42 例患者,对照组为同期诊断为普通细菌性肺炎的30例患者,上述病例均行纤维支气管镜检查并行BALF的GM试验,同时行血清GM试验。观察病例组及对照组中血清及BALF GM试验 I 值的不同,分析在不同的诊断阈值下,两种标本的GM试验对诊断IPA的价值。通过ROC曲线分析确定血清及BALF两种标本GM试验的不同诊断阈值。

结果

血清和 BALF 这两种不同的标本组内比较,GM试验I 值差异有统计学意义(P< 0.05)。不同的诊断阈值下,BALF GM 试验诊断 IPA的敏感度均优于血清。通过绘制ROC曲线,结果显示病例组及对照组血清和 BALF的GM试验诊断阈值分别为 0.50、1.0,曲线下面积分别为 0.824 及 0.881。

结论

血清和 BALF 标本 GM 试验对 IPA 的诊断均有较好的临床价值,BALF GM 试验优于血清GM试验,两者联合应用可提高IPA的诊断率,并且两种标本诊断IPA时应选择合适的阈值。

Abstract: Objective

To compare the value of GM test of serum and bronchoalveolar lavage fluid (BALF) in the diagnosis of invasive pulmonary aspergillosis (IPA).

Methods

Forty-two patients diagnosed with IPA in the Department of Respiratory and Critical Care Medicine and other clinical departments of our hospital were included in the case group, and 30 patients diagnosed with common bacterial pneumonia were included in the control group. All of the above patients underwent fiberoptic bronchoscopy, BALF GM test and serum GM test. The difference of GM test Ⅰ values in serum and BALF between the case group and the control group was observed, and the value of GM test in the diagnosis of IPA of the two specimens under different diagnostic thresholds was analyzed. Different diagnostic thresholds for GM test of serum and BALF specimens were determined by ROC curve analysis.

Results

There were significant differences in GM test Ⅰ values between BALF and serum (P< 0.05). The sensitivity of BALF GM test to IPA was better than that of serum at different diagnostic thresholds. The ROC curve showed that the GM test diagnostic threshold of serum and BALF in the case group and the control group were 0.50 and 1.0, and the areas under the curve were 0.824 and 0.881, respectively.

Conclusion

Both serum GM test and BALF sample GM test have good clinical value for diagnosis of IPA, BALF GM test is superior to serum GM test, the combination of the two can improve the diagnosis of IPA, and the appropriate threshold should be selected for the diagnosis of IPA.
