Abstract:ObjectiveTo determine the clinical value of plasma 13βD glucan assay for diagnosis of fungal rhinosinusitis.MethodsClinical data of 87 patients underwent surgical treatment for nasal diseases in our department was analyzed retrospectively. According to the postoperative pathological results, all the patients were divided into two groups, experimental group (fungal rhinosinusitis group,n=41) and control group(n=46). The plasma levels of 13βD glucan in all the patients of both groups were detected and compared. The specificity and sensitivity of plasma 13βD glucan assay for the diagnosis of fungal rhinosinusitis were calculated.ResultsThe average preoperative plasma level of 13βD glucan in the experimental group (18.3±3.2 pg/ml) was higher than that of the control group (2.5±3.4 pg/ml) with statistically significant difference (t=22.24,P<0.05). In the experimental group, the postoperative plasma level of 13βD glucan (2.8±2.6 pg/ml) was significantly lower than the preoperative level (18.3±3.2 pg/ml)with statistically significant difference (t=24.07,P<0.05). For the diagnosis of fungal rhinosinusitis via detection of plasma 13βD glucan, the sensitivity was 95.1% and specificity was 84.8%.ConclusionsPlasma 13βD glucan assay for diagnosis of fungal rhinosinusitis is reliable and convenient with high sensitivity. Meanwhile, this assay can be used for monitoring the surgical efficacy. Therefore, the detection of plasma 13βD glucan is worthy of being widely applied to clinical medicine.
