目的 探讨联合荧光定量聚合酶链反应(PCR)与血清半乳甘露聚糖(GM)方法用于诊断血液恶性肿瘤/造血干细胞移植患者侵袭性曲霉病(IA)的价值.方法 对80例怀疑侵袭性真菌感染的血液恶性肿瘤/造血干细胞移植患者共计205份血清标本同时进行定量PCR和血清半乳甘露聚糖的检测,根据IA诊断标准,分析定量PCR方法与GM方法的符合率及两者联合用于IA诊断时的意义.结果 5例患者确诊IA,20例临床诊断IA,34例拟诊IA,21例除外IA.定量PCR方法与GM符合率为77.5%.当定量PCR和GM同时阴性时,诊断侵袭性曲霉感染阴性预测值可达90.9%;当二者同时阳性时,阳性预测值可达100%.结论 定量PCR方法与GM方法具有良好符合率,联合两种方法有助于提高IA诊断的准确性.
