“…More recently, proof that VZV can cause serious neurological disease, often in the absence of rash, has been based on serologic analyses to detect VZV-specific antibodies (Shoji et al, 1976), as well as intracellular antigen in patients with zoster meningoencephalitis, cranial and spinal radiculoneuritis (Peters et al, 1979), and intrathecal production of anti-VZV antibodies (Martinez-Martin et al, 1985; Echevarria et al, 1987). Most recently, combined PCR and antibody testing revealed that VZV causes 5% to 27% of all aseptic meningitis (Koskiniemi et al, 2001; Hausfater et al, 2004; Kupila et al, 2006; Frantzidou et al, 2008), which is not altogether surprising because PCR has already shown that VZV causes zoster sine herpete (Gilden et al, 1994), vasculopathy (Gilden et al, 1996), acute (Gilden, 1994) and recurrent (Gilden et al, 2009) myelopathy, acute cerebellar ataxia (Moses et al, 2006; Ratzka et al, 2006), and retinal necrosis (el Azazi et al, 1991; Galindez et al, 1996), all without rash.…”
