And the objectives of this study were: 1) to assess changes in neuroendocrine hormones of HPA axis and HPT axis in patients with BD after psychotropic drug treatment; 2) to determine differences in the above neuroendocrine hormones between psychotropic drug monotherapy and polytherapy treated patients.Methods: This study was a retrospective study that included 188 subjects.Results: After psychotropic drugs treatment, TSH levels increased significantly from baseline (p< 0.001) and FT3, TT3, FT4, TT4, ACTH and CORT levels decreased significantly from baseline (p< 0.001, p< 0.001, p< 0.001, p=0.007, p=0.039, p=0.031). There was no significant difference in hormonal changes between the monotherapy group and the polytherapy group, even though the polytherapy group was further divided into 4 subgroups. And there was no correlation between changes in hormones and treatment duration.Conclusion: Although the incidence of significant HPT axis and HPA axis dysfunction after psychotropic drug treatment is low in patients with BD who have normal baseline neuroendocrine hormone levels, psychotropic drug treatment does suppress HPT axis and HPA axis function irrespective of the use of psychotropic drugs alone or in combination, and duration of psychotropic drug treatment. Therefore, even patients with BD who have normal baseline levels of neuroendocrine hormones should have their neuroendocrine hormone levels regularly monitored after psychotropic drug medication. But, the interval of monitoring can be slightly longer, which can be once every six months after taking psychotropic drugs.Keywords: bipolar disorder, psychotropic drugs, neuroendocrine hormones |
