Abstract:

Objective To evaluate the detection of （1,3）-beta-D-glucosan（BDG）（G test） in hematological patients with invasive fungal disease （IFD）. Methods A retrospective study was performed for 399 hematological malignancy patients,plasma G tests were performed for 2-3 times a week. The Principle and Diagnostic Criteria of the Disease of Hematopoietic System/Tumor in Patients with Invasive Fungal Infection（Revised Edition） was used as criteria. The diagnostic significance was evaluated by SPSS 11.5 software. Results The sensitivity of G test was 78.5% for the diagnosis of IFD,the specificity was 79.8%,the positive predictive value was 75.0%, and the negative predictive value was 82.7%. Conclusions Plasma BDG is correlated with IFD. Plasma G test should be taken 2-3 times per week. Combined with medical imaging,G test could improve the diagnosis of IFD and treatment efficiency and reduce the medical burden of patients.
