(1-3)-Beta-D-Glucan (BG) reactivity was tested in serum samples from 28 patients with human immunodeficiency virus infection or a hematological malignancy and Pneumocystis jirovecii pneumonia (PCP) and 28 control patients. The sensitivity and specificity of BG detection with the Fungitell assay for PCP were 100 and 96.4%, respectively, using a cutoff value of 100 pg/ml. Serum BG testing looks promising for the noninvasive diagnosis of PCP. Our data suggest that a higher cutoff value for the diagnosis of PCP than for the diagnosis of invasive aspergillosis or candidiasis could be used safely and will improve the specificity of the test.
(1-3)-β-D-葡聚糖(BG)反应性在 28 例人类免疫缺陷病毒感染或血液系统恶性肿瘤合并肺孢子菌肺炎(PCP)患者和 28 例对照患者的血清样本中进行了检测。使用 100pg/ml 的截断值,Fungitell 检测 BG 对 PCP 的敏感性和特异性分别为 100%和 96.4%。血清 BG 检测似乎是一种很有前途的非侵入性诊断 PCP 的方法。我们的数据表明,用于诊断 PCP 的截断值高于用于诊断侵袭性曲霉病或念珠菌病的截断值,这样做是安全的,并且可以提高该检测的特异性。
