Abstract

Cerebrospinal fluids (CSF) of 245 neurological and 194 psychiatric patients were tested for viral antibodies and interferon. Complement dependent neutralizing antibodies to Herpesvirus hominis 1 were found in the CSF of patients with encephalitis (50.6%), meningitis (35.4%), lesions of peripheral nerves (36.9%), sclerosis multiplex (41.2%), schizophrenia (31.9%), senile dementia (51.4%), mental retardation (11.1%), ethylism (43.5%). Neutralizing antibodies to tick-borne encephalitis virus were found in the CSF of 38% patients with encephalitis, in 14% meningitis, 11% lesions of peripheral nerves and also in 5.6--11.8% of psychiatric patients. In encephalitis, meningitis and in lesions of peripheral nerves were found in the CSF frequently plaque neutralizing antobidies to the tick-borne orbivirus Lipovník, complement-fixing antibodies to lymphocytic choriomeningitis virus and hemagglutination inhibiting antibodies to measles virus. In multiple sclerosis were detected CSF antibodies to measles virus (44%), Herpesvirus hominis 1 (41.2%) and Lipovník virus (52.6%). In neurological patients were observed CSF antibodies simultaneously to two or three viruses in 16.7 to 40.6%, while in psychiatric patients in zero to 4.6%. CSF interferon was found in psychiatric patients with an equal or even higher incidence (33.7 to 57.1%) than in the neurological patients (29.6--38.6%, in multiple sclerosis only 16.7%). Non-interferon virus inhibitors were excluded. The evaluation of the ratio of serum and CSF titers of viral antibodies and of interferon indicated local synthesis of both in the central nervous system -- with the exception of antibodies to Herpesvirus hominis 1 in CSF of some patients with very high titres in serum and probable lesions of the blood brain barrier.
