In een recente studie hebben Zhang en collega's vonden m.b.v. de PCR-techniek
genetisch materiaal (RNA) van het Borna-virus bij 12,7% van de CVS-patiënten.
Het Borna-virus werd eerder in verband gebracht met CVS
(klik hier, hier,
hier en hier), maar
Lipkin en collega's konden volgens een studie uit 1999 geen RNA van het Borna-virus vinden.
Het Borna-virus is een neurotropisch virus
dat zich volgens Horie
genesteld heeft in het DNA van de gastheer. Volgens anderen zijn ook nieuwe infecties (van buitenaf) ziekmakend,
bijv. in woelmuizen.

Abstract
Borna disease virus (BDV) is a non-cytolytic, neurotropic RNA virus
that can infect a wide variety of vertebrate species from birds and primates to humans.
Several studies have been carried out
to investigate whether BDV is associated with neuropsychiatric diseases.
However, this association is still inconclusive.
Two panels of subjects consisting of 1,679 various neuropsychiatric patients and
healthy people from three western China provinces were enrolled in this study.
BDV p24 or p40 RNA in peripheral blood mononuclear cells (PBMCs) were detected
in the first panel of 1,481 subjects
using reverse transcription quantitative polymerase chain reaction (RT-qPCR) and
cerebrospinal fluid (CSF) samples from the BDV RNA-positive individuals
were subjected to BDV p24 antibodies testing by enzyme-linked immunosorbent assay (ELISA).
BDV p24 or p40 RNA in PBMCs and p24 antibodies in plasma
were detected in the second panel of
198 subjects by RT-qPCR and Western blot.
A higher prevalence for BDV RNA was demonstrated in patients with
viral encephalitis (6.70 %), Guillain-Barré syndrome (6.70 %),
schizophrenia (9.90 %) and chronic fatigue syndrome (CFS) (12.70 %)
compared to healthy controls in the first panel.
CSF p24 antibodies were demonstrated in three viral encephalitis patients,
two schizophrenia patients and two major depressive disorder (MDD) patients.
The prevalences of p24 antibodies in plasma from patients with
viral encephalitis (13.24 %), multiple sclerosis (25.00 %) and Parkinson's disease (22.73 %)
were significantly higher than healthy controls.
This study demonstrates that
BDV infection also exists in humans from three western China provinces, and
suggests the involvement of the contribution of BDV in the aetiology of Chinese patients
with some neuropsychiatric disorders,
including viral encephalitis, schizophrenia, CFS, multiple sclerosis and Parkinson's disease.
