Antibodies to varicella-zoster virus and three other herpesviruses and survival in adults with glioma

Abstract
Background
Lifetime exposure to the varicella-zoster virus (VZV) has been consistently inversely associated with glioma risk, however the relationship of VZV with survival in adults with glioma has not been investigated. In this study, we analyzed survival of adults with glioma in relation to their antibody measurements to 4 common herpes viral infections, including VZV, measured post-diagnosis.
Materials and Methods
We analyzed IgG antibody measurements to VZV, cytomegalovirus (CMV), herpes simplex virus 1/2 (HSV), and Epstein-Barr virus (EBV) collected from 1378 adults with glioma diagnosed between 1991 and 2010. Blood was obtained a median of 3 months after surgery. Associations of patient IgG levels with overall survival were estimated using Cox models adjusted for age, sex, self-reported race, surgery type, dexamethasone usage at blood draw, and tumor grade. Models were stratified by recruitment series and meta-analyzed to account for time-dependent treatment effects.
Results
VZV antibody seropositivity was associated with improved survival outcomes in adults with glioma (Hazard ratio, HR=0.70, 95% Confidence Interval 0.54-0.90, p=0.006). Amongst cases who were seropositive for VZV antibodies, survival was significantly improved for those above the 25th percentile of continuous reactivity measurements versus those below (HR=0.76, 0.66-0.88, p=0.0003). Antibody seropositivity to EBV was separately associated with improved survival (HR=0.71, 0.53-0.96, p=0.028). Antibody positivity to two other common viruses (CMV, HSV) was not associated with altered survival.
Conclusions
Low levels of VZV or EBV antibodies are associated with poorer survival outcomes for adults with glioma. Differential immune response rather than viral exposure may explain these findings.
