This study determined the value of (1,3)-β-d-glucan (BDG), Candida mannan (MN) and Candida species-specific DNA as surrogates for diagnosis of candidaemia. Thirty-nine patients yielding Candida species in blood cultures were investigated for presence of BDG, MN and Candida species-specific DNA in serum samples. The Candida spp. bloodstream isolates included C. albicans (n = 16), C. tropicalis (n = 10), C. parapsilosis (n = 7), C. glabrata (n = 3) and C. dubliniensis (n = 3). Positivity of the three markers was as follows: Candida DNA for corresponding Candida species, 100%; BDG, 87%; MN, 59%. Despite varying sensitivities of these biomarkers, they provided a useful adjunct to the diagnosis of candidaemia.
本研究旨在确定(1,3)-β-D-葡聚糖(BDG)、甘露聚糖(MN)和念珠菌种特异性 DNA 作为念珠菌血症诊断替代物的价值。对 39 例血液培养出念珠菌的患者进行了血清样本中 BDG、MN 和念珠菌种特异性 DNA 的检测。念珠菌 spp.血流分离株包括白念珠菌(n = 16)、热带念珠菌(n = 10)、近平滑念珠菌(n = 7)、光滑念珠菌(n = 3)和都柏林念珠菌(n = 3)。三种标志物的阳性率如下:与相应念珠菌属的念珠菌 DNA,100%;BDG,87%;MN,59%。尽管这些生物标志物的敏感性不同,但它们为念珠菌血症的诊断提供了有用的辅助手段。
