title: Relation between psychoneuroendocrine profile in stressful conditions and antibodies to herpesvirus 6 and 7.
abstract: The aim of the present study is to evaluate whether the individual susceptibility to infectious disease is influenced by the psychological profile of cadets exposed to stressful events associated with military lifestyle in academy and if the neuroendocrine responses to stressful events is related with humoral immunity estimated by measuring antibody titres to human herpesvirus (HHV-6)7 (HHV-7) and to what extent it is influenced by personality traits. It has been observed that cadets with lower psychoaptitude scores (1-2) have a significant higher susceptibility to infectious disease (x2=7.95; p=0.019) compared to subjects with higher scores. A positive relationship between cortisol and antibody titers to HHV-6 (r=0.304; p=0.024) it has been found. It can be interesting to observe that antibody titers on HHV-6 are also related to psychoaptitude profile (r=0.239; p=0.044). The antibody titers to HHV-7 are negatively related to the 5 scales of BFQ and in particular with subdimension Co (cordiality) of BFQ (r=0.401; p=0.002). The survey carried out on over 1,500 cadets of the Military Academy of Modena shows that the susceptibility to infectious diseases during the first six months of admission to the Academy seem to be influenced by the psychoaptitudinal profile. The finding of a positive relationship between serum cortisol and antibody vs HHV-6 suggests that the impairment of the immune system linked to circulatory cortisol levels may induce a reactivation of a latent herpesvirus 6 with related increase of antibody titers.
