Abstract

The diagnostic reliabilities of three cytomegalovirus (CMV) nucleic acid amplification assays of cerebrospinal fluid (CSF) were compared by using CSF samples from human immunodeficiency virus-infected patients with a postmortem histopathological diagnosis of CMV encephalitis (n = 15) or other central nervous system conditions (n = 16). By using a nested PCR assay, the quantitative COBAS AMPLICOR CMV MONITOR PCR, and the NucliSens CMV pp67 nucleic acid sequence-based amplification assay, sensitivities were 93.3, 86.6, and 93.3%, respectively, and specificities were 93.7, 93.7, and 87.5%, respectively. The COBAS AMPLICOR assay revealed significantly higher CMV DNA levels in patients with diffuse ventriculoencephalitis than in patients with focal periventricular lesions.

摘要

通过使用来自人类免疫缺陷病毒感染患者的脑脊液(CSF)样本,比较了三种脑脊液巨细胞病毒(CMV)核酸扩增检测方法的诊断可靠性,这些患者经尸检组织病理学诊断为CMV脑炎(n = 15)或其他中枢神经系统疾病(n = 16)。使用巢式PCR检测、定量COBAS AMPLICOR CMV MONITOR PCR和基于核酸序列扩增的NucliSens CMV pp67检测,敏感性分别为93.3%、86.6%和93.3%,特异性分别为93.7%、93.7%和87.5%。COBAS AMPLICOR检测显示,弥漫性脑室脑炎患者的CMV DNA水平显著高于局灶性脑室周围病变患者。
