JC virus DNA was detected by PCR in the cerebrospinal fluid of 17 of 23 (73.9%) patients with confirmed cases of progressive multifocal leukoencephalopathy and 2 of 48 (4.2%) controls without progressive multifocal leukoencephalopathy. The sensitivity and specificity of this PCR were 74 and 95.8%, respectively, while the positive and negative predictive values were 89.5 and 88.5%, respectively.
在23例确诊为进行性多灶性白质脑病的患者中,有17例(73.9%)的脑脊液通过聚合酶链反应(PCR)检测到JC病毒DNA;在48例无进行性多灶性白质脑病的对照者中,有2例(4.2%)检测到该病毒DNA。此PCR检测的敏感性和特异性分别为74%和95.8%,阳性预测值和阴性预测值分别为89.5%和88.5%。
