We have conducted a double-blind study to assess the possible
involvement of the human herpesviruses (HHVs) HHV6, HHV7, Epstein-Barr virus (EBV), and cytomegalovirus in chronic fatigue syndrome (CFS) patients compared to age-, race-, and gender-matched controls. The CFS
patient population was composed of rigorously screened civilian and
Persian Gulf War veterans meeting the Centers for Disease Control
and Prevention's CFS case definition criteria. Healthy control
civilian and veteran populations had no evidence of CFS or any other
exclusionary medical or psychiatric condition. Patient peripheral blood
mononuclear cells were analyzed by PCR for the presence of these HHVs.
Using two-tailed Fisher's exact test analyses, we were unable to
ascertain any statistically significant differences between the CFS
patient and control populations in terms of the detection of one or
more of these viruses. This observation was upheld when the CFS
populations were further stratified with regard to the presence or
absence of major axis I psychopathology and patient
self-reported gradual versus acute onset of disease. In tandem,
we performed serological analyses of serum anti-EBV and anti-HHV6
antibody titers and found no significant differences between the CFS
and control patients.
