We used an indirect enzyme immunoassay to describe the evolution of serum levels and the intrathecal production of IgG, IgA, and IgM antibodies to varicella-zoster virus (VZV) in eight patients with a syndrome of acute aseptic meningitis (AAM) and evidence of intrathecal production of VZV-specific IgG antibodies. Four of the eight patients showed no cutaneous zoster while hospitalized. Our results suggested an etiologic relation between VZV and AAM in all cases. Furthermore, we observed some differences in the pattern of evolution of antibodies in serum and cerebrospinal fluid in relation to the presence or absence of cutaneous lesions in our patients. These differences could reflect different pathogenic mechanisms in the spread of VZV to the central nervous system and in the production of the AAM syndrome.
IgG antibodies to varicella-zoster virus (VZV) were detected by indirect enzyme-immunoassay (EIA) in CSF of two patients with acute aseptic meningitis syndrome (AAMS) not associated with evident cutaneous lesion or recent history of zoster infection. Their characteristic features and serological data are compared with those observed in two patients with AAMS and zoster cutaneous lesions, and in 13 patients with AAMS of unknown or other etiology. According to several indexes applied to assess the origin of the detected antibodies, it is concluded that VZV IgG antibodies are of intrathecal production. The possible etiologic relationship between the neurological syndrome and the detection of VZV antibodies in CSF is discussed. Routine serological procedures are proposed for the diagnosis of CNS acute infections of probable viral etiology that should provide additional data on these rarely described cases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
