目的:探讨血浆(1,3)-β-D 葡聚糖检测(G 试验)用于侵袭性真菌感染(IFI)临床早期诊断的临床应用价值。方法选取住院治疗的 IFI 患者共180例,将其分为拟诊组(84例),确诊组(49例)以及临床诊断组(47例);另选取同期住院治疗的细菌感染患者(细菌组)44例以及身体健康者(正常组)53名;均使用MB-80微生物动态快速检测系统进行检测,同时进行血浆 G 试验,结果使用 ROC 曲线评价,分析 G 试验的最佳临界值。结果以白色假丝酵母菌为主的呼吸道感染为 IFI 的常见感染;与细菌组(9.4 pg/mL)及正常组(7.8 pg/mL)血浆葡聚糖含量中位数相比,IFI 组血浆 G 试验(29.3 pg/mL)明显较高,且差异存在统计学意义(Z =-2.41,P =0.015;Z =-2.19,P =0.028);与确诊组(105.8 pg/mL)及临床诊断组(46.3 pg/mL)血浆葡聚糖含量中位数相比,拟诊组(8.1 pg/mL)明显较低,且差异存在统计学意义(Z =-2.99,P =0.003;Z =-2.19,P =0.027);分析 ROC 曲线可知,当 cutoff 值为9.35 pg/mL 时,其特异性(67.2%)、敏感性(70.3%)以及阴/阳性预测值(69.3%/65.8%)均为最佳,且与培养法一致性较好,其 Kappa 值为0.603,差异有统计学意义(P =0.036)。结论于侵袭性真菌感染的早期临床诊断中,血浆 G 时间预警效果良好,可广泛使用。

Objective To discuss the clinical value of plasma (1,3)-β-D -glucan detection (G test) for early diagnosis of invasive fungal infections (IFI).Methods A total of 180 cases of IFI were divided into suspec-ted group (84 cases),diagnosed group (49 cases)and clinical diagnosis group (47 cases).At the same period,the other 44 hospitalization patients with bacterial infection and 53 healthy persons were selected.All personnel were par-ticipated in the experiment using the MB -80 system for rapid detection of microbial dynamic detection,simultaneous plasma G test was evaluated using ROC curve analysis G optimal threshold test.Results Candida albicans was a common respiratory infections of IFI.Compared with bacterial group (9.4pg/mL)and normal group (7.8pg/mL) plasma glucan content median,IFI group plasma G test (29.3pg/mL)was significantly higher,and the differences were statistically significant(Z =-2.41,P =0.015;Z =-2.19,P =0.028),Compared with the median plasma glu-can content of the diagnosis group (105.8pg/mL)and clinical diagnosis group (46.3pg/mL),to be diagnosed group (8.1pg/mL)was significantly lower,and the differences were statistically significant(Z =-2.99,P =0.003;Z =-2.19,P =0.027).ROC curve analysis showed that when the cutoff value was 9.35pg/mL,its specificity (67.2%), sensitivity (70.3%)and negative /positive predictive value (69.3% /65.8%)were the best,and more consistent with the culture method,the Kappa value was 0.603,the difference was statistically significant (P =0.036 ). Conclusion In the early diagnosis of IFI,plasma G test has good results and can be widely used.
