Detection of varicella-zoster virus-specific DNA sequences in cerebrospinal fluid from patients with acute aseptic meningitis and no cutaneous lesions.
Acute aseptic meningitis (AAM) is considered as an uncommon manifestation of varicella-zoster virus (VZV) recrudescence and is usually regarded as a complication of the cutaneous infection in patients with impaired cellular immunity. Indirect evidence suggests, however, that VZV-associated AAM may also respond to direct spread of the virus to the leptomeninges from the cells supporting the latency. The polymerase chain reaction (PCR) was used to amplify VZV-specific DNA sequences in serial cerebrospinal fluid (CSF) samples from 21 patients with AAM, who presented laboratory evidence of intrathecal production of VZV-specific antibody on follow-up. Eleven of these patients never showed cutaneous zosteriform lesions. VZV-DNA sequences were detected in the CSF from all patients with cutaneous zoster, as well as from six patients (55%) lacking skin lesions. Viral DNA sequences were present in six cases before the rise in specific antibody was seen in CSF, disappearing during follow-up in the seven positive cases. These results support the proposed involvement of VZV in the etiology of AAM seen among normal young adults and strongly suggest that the virus can reach directly and infect the CNS from the latently infected spinal ganglia.
