EPSTEIN-BARR-VIRUS GENOMIC SEQUENCES AND SPECIFIC ANTIBODIES IN CEREBROSPINAL-FLUID IN CHILDREN WITH NEUROLOGIC COMPLICATIONS OF ACUTE AND REACTIVATED EBV INFECTIONS

Four children with infectious mononucleosis (IM) and one with reactivated Epstein-Barr virus (EBV) infection had concomitant central nervous system disorders. Cerebrospinal fluid (CSF) samples from all five patients contained EBV genomic sequences and EBV-specific antibodies in the neurologic stage, but not during convalescence. Cerebrospinal fluid from two non-neurologic IM patients had neither EBV DNA nor EBV antibodies. The EBV-positive CSF of the five with neurological disorders were aseptic in culture and all negative for other human herpesvirus DNAs and antibodies: herpes simplex virus types 1 and 2, cytomegalovirus, varicella-zoster virus, and human herpesvirus 6. Epstein-Barr virus DNA and EBV antibodies were not detected in the CSF of 17 EBV-seropositive patients with mumps meningitis, rubella encephalitis, unknown febrile convulsion, or partial epilepsy. It is suggested that EBV plays a causal role in neurologic manifestations in patients with acute and reactivated EBV infections, through direct viral invasion and immunopathological reactions.
