Epstein-barr virus DNA in the cerebrospinal fluid of patients with human immunodeficiency virus infection and central nervous system disorders.
Routine search for herpesvirus types 1-5 by nested polymerase chain reaction revealed Epstein-Barr virus (EBV) DNA in the cerebrospinal fluid (CSF) of ten out of seventy-nine patients with human immunodeficiency virus (HIV) infection and central nervous system (CNS) disorders not associated with the presence of primary CNS lymphomas. One out of the ten CSF samples was positive for EBV DNA only, six were also positive for microbial agents of recognised neurological pathogenicity while the remaining three samples had a high content of HIV p24 Ag. When six available CSF samples out of the ten EBV DNA positive specimens were investigated for an intrathecal EBV antibody response, all six samples proved EBV antibody-free. The concurrent detection of neurotropic infectious agents and the absence of EBV antibodies in the CSF contribute to the uncertainty on the role of EBV in the neurological illness of the patients studied. One hypothesis considered is that the presence of EBV DNA in the CSF of a large fraction of the ten patients under study is an incidental event associated with EBV reactivation in the host's peripheral blood monocytes, but not related to the genesis of neurological disorders.
