Popis: JC virus (JCV) load was determined by using quantitative polymerase chain reaction in cerebrospinal fluid (CSF) of 12 patients with AIDS-associated progressive multifocal leukoencephalopathy (PML) and compared with clinical outcome. JCV loads varied widely (3‐7 log10 JCV equivalents/mL of CSF) and were apparently not related to absolute CD4 cell counts or CSF and plasma human immunodeficiency virus type 1 loads. A significant correlation was observed between JCV load and survival time (Spearman’s rank correlation, 20.83; ). Moreover, CSF JCV load decreased and then became undetectable in P ! .01 1 PML patient receiving cidofovir treatment, and this was associated with clinical improvement. These results show that CSF JCV load may be useful as a prognostic parameter and in monitoring the effectiveness of anti-JCV therapies in PML patients. The human polyomavirus JC virus (JCV) is the causative agent of progressive multifocal leukoencephalopathy (PML), a fatal demyelinating neurodegenerative disease associated with impaired cellular immunity [1]. The prevalence of PML in AIDS patients is »4% [1]. PML results from lytic infection of oligodendrocytes, leading to foci of demyelinization in the cerebral white matter [1]. JCV DNA detection in cerebrospinal fluid (CSF) is a reliable diagnostic marker of PML, particularly when combined with a typical magnetic resonance imaging pattern [1‐5]. However, most available JCV polymerase chain reaction (PCR) methods provide no information on virus load. Here, by using quantitative PCR, we investigated JCV load in CSF of AIDS-associated PML patients.
