SO J Infect Dis. 1994 May;169(5):1138-41. Unique Identifier : AIDSLINE MED/94223080 AB Using polymerase chain reaction (PCR), 34 cerebrospinal fluid (CSF) samples from 28 patients with progressive multifocal leukoencephalopathy (PML) were analyzed. As controls, 116 samples were evaluated from 82 human immunodeficiency virus type 1 (HIV-1)-infected patients and 1 HIV-1-negative patient. Of the HIV-1-positive patients, 23 had cerebral toxoplasmosis, 10 had HIV leukoencephalopathy, and 49 had other neurologic complications. Detection of JC virus (JCV) DNA in CSF was increased 10-fold by the addition of carrier DNA before phenol-chloroform-isoamyl alcohol extraction. The primer pair JC 26/29, from the VP1/large T region, had a limit of detection of 10(5) JCV DNA molecules/100 microL. The primer pair JC 36/39, located in the large T gene region, had a 100-fold lower limit of detection. With JC 26/29, the sensitivity was 43% (12/28) and specificity was 100%. Using JC 36/39, sensitivity increased to 82% (23/28), and false-positive results were not observed. Diagnosis of PML is greatly aided by PCR analysis of CSF.
