In order to investigate the possible involvement of viruses in Multiple Sclerosis (MS), the study evaluated
the presence of viral genomic sequences in cerebrospinal fluid (CSF), as markers of viral replication within the
central nervous system (CNS). A total of 85 CSF samples were collected from 38 MS patients, 28 patients with other
neurological diseases and 19 subjects without neurological diseases. Using nested-PCR, the investigation focused
on the presence of human herpes virus DNA, including herpes simplex virus 1 (HSV-1) and 2 (HSV-2), the Epstein-Barr
virus (EBV), varicella zoster virus (VZV), human cytomegalovirus (HCMV), human herpes virus 6 (HHV-6) and JC virus
(JCV). All the CSF samples from the individuals without neurological diseases were negative for viral DNA.
Genomic sequences of HSV-1, HCMV, EBV, HHV6, and JCV were found in patients with MS and other neurological diseases
without significant differences between the two groups. VZV DNA was detected more frequently (P < 0.05) in the MS
group (31.6%), particularly among the relapsing-remitting MS patients (43.5%), compared with patients with other
neurological diseases (10.7%). In addition, the results indicated that JCV and HHV-6 were replicating actively
in the CNS of a small, but significant number of patients with MS and other neurological diseases. Most importantly,
the study revealed a high frequency of VZV DNA in the CSF of patients with MS, suggesting a possible role of this
virus in the pathogenesis of MS.
