Mannan antigen (MA) in neonates as a marker of invasive candidemia is not well studied, although 4% of all neonatal intensive care unit admissions are attributed to Candida spp. infections. The aim of this case-control study was to evaluate the performance of MA (Platelia™ Candida AgPluskit, Bio-Rad) in neonates who had rectal Candida colonization or in non-colonized controls. We cultured 340 rectal swabs of neonates and MA was negative in 24/25 C. albicans colonized (96% specificity) and in 30/30 non-colonized neonates (100% specificity). The results indicate a high specificity of the assay, which could be useful in neonates with possible candidemia.
尽管新生儿重症监护病房中4%的入院病例归因于念珠菌属感染，但作为侵袭性念珠菌血症标志物的新生儿甘露聚糖抗原（MA）尚未得到充分研究。本病例对照研究的目的是评估MA（Bio-Rad公司的Platelia™念珠菌AgPlus试剂盒）在直肠念珠菌定植的新生儿或未定植的对照新生儿中的表现。我们培养了340份新生儿直肠拭子，在24/25例白色念珠菌定植的新生儿中MA呈阴性（特异性96%），在30/30例未定植的新生儿中MA也呈阴性（特异性100%）。结果表明该检测方法具有高特异性，这可能对疑似念珠菌血症的新生儿有用。
