distinct activation of the sympathetic adreno medullar system and hypothalamus pituitary adrenal axis following the Caloric Vestibular Test in healthy subjects
PLOS ONE, 2018Co-Authors: Sebastian Cozma, Cristina Mihaela Ghiciuc, Lisandra Damian, Vittorio Pasquali, Angelo Saponaro, Elena Catalina Lupusoru, Francesca Romana Patacchioli, Lucia Corina DimacozmaAbstract:Introduction The Vestibular acute stress induces reversible alert-like reactions that involve the sympathetic adrenal-medullar system and hypothalamic-pituitary-adrenal axis responses. The present study aimed to evaluate salivary α-amylase and salivary cortisol production in relation with cardiovascular reactivity induced by acute stress in healthy subjects. Material and methods Forty-eight young healthy male volunteers were examined under basal conditions and at various times after reaching the maximal nystagmic reaction following air Caloric Vestibular Test. Heart rate, systolic blood pressure, diastolic blood pressure and mean arterial pressure were recorded at the same time as measurement of the salivary α-amylase and salivary cortisol. At the end of the Caloric Vestibular Test session, perceived stress scale questionnaires were administered to measure the self-perceived stress impact induced by the task, and individual scores were compared with those measured on the enrollment day. Results Following Caloric Vestibular Test-evoked vertigo, salivary α-amylase and cortisol showed distinct trends in their production after acute stress: Student’s t-Test was used to compare the α-amylase vs cortisol slopes of the respective interpolated regression lines, and the difference was significant (t = -3.283; p<0.001); an increase in salivary cortisol production corresponded with a decrease in the salivary α-amylase concentration. In addition, salivary biomarker modifications were associated with consistent changes in the heart rate, systolic blood pressure and mean arterial pressure. Conclusions Using the air Caloric Vestibular Test task as a stressor, the present study demonstrated a connection between the acute hormonal stress response to Vestibular stimulation and cardiovascular output. However, further research is needed before we can define the potential importance of the consistent cardiovascular activity changes evoked by Vestibular stimulation and the possible functional consequences for cardiovascular regulation and orthostatic tolerance in humans.
