Plasma cortisol in first episode drug-naïve mania: Differential levels in euphoric versus irritable mood

Abstract: Background Dysregulation of HPA axis has been widely described in subjects with bipolar disorder (BD), including changes in cortisol levels during mood episodes and euthymia. However, most of the studies were done with medicated BD patients with variable length of illness, which was shown to interfere on peripheral cortisol levels. Therefore, the present study aims to evaluate plasma cortisol levels in drug-naïve BD subjects during the first manic episode, as well as investigate the relationship between plasma… Show more

“…Multiple deleterious effects can occur when CRH is secreted excessively, including inhibited BDNF secretion, neuroplasticity, and subgenual prefrontal cortex function. Hypercortisolism also leads to behavioral hyperarousal, insomnia, and the desynchronization of critical biological rhythms; it also significantly interferes with sleep and sexual function [77]. In an attempt to limit the deleterious effects of hypercortisolism, a number of antiglucocorticoid agents have been studied in the treatment of mood disorders (reviewed in [78]).…”

“…Mas em estudo recente, pacientes em primeiro episódio maníaco sem tratamento apresentaram níveis de cortisol plasmático diminuídos em relação aos controles, sendo níveis elevados associados positivamente com a presença de irritabilidade (disforia), e elevação de humor (euforia) associada a níveis mais baixo de cortisol (VALIENGO et al, 2012).…”

“…Todas as pacientes do grupo TAB e a grande maioria do grupo TPB relataram uso de pelo menos uma medicação, estando a maioria em uso de associação de medicamentos das classes dos estabilizadores de humor, antipsicóticos e antidepressivos. Embora alguns desses medicamentos tenham sido relacionados a alterações dos níveis de cortisol (VENKATASUBRAMANIAN et al, 2010;WATSON et al, 2007;HEIM & NEMEROFF, 1999;EROGLU et al,1979), a maior parte dos estudos clínicos de avaliação do perfil hormonal do eixo HHA são realizados na vigência do uso de medicamentos habitualmente prescritos para a condição estudada (VALIENGO, 2012;CARVALHO-FERNANDO et al, 2012;KAMALI et al, 2008;JURUENA et al, 2006JURUENA et al, , 2009JURUENA et al, , 2010JURUENA et al, , 2013WATSON et al, 2007;DREVETS, et al 2002).…”
