Affective disorders are a medical condition with a complex biological pattern of etiology, involving genetic and epigenetic factors, along with different environmental stressors. Increasing numbers of studies indicate that induction of oxidative and nitrosative stress (O&NS) pathways, which is accompanied by immune-inflammatory response, might play an(More)
Depression is considered as a chronic and recurring illness with functional impairment, significant disability, morbidity and mortality. Despite the extensive research carried out on depression, its pathophysiology is still poorly understood. An important problem concerning research into depressive disorder is the lack of biological markers which could(More)
AIM The growing body of evidence suggests that magnesium levels can serve as a marker of major depressive disorder (MDD), but findings from clinical trials remain inconclusive. The aim of the presented study was to determine the magnesium concentration in serum of patients with MDD (in the active stage of the disease or in remission) and to analyze the role(More)
OBJECTIVES Zinc may be involved in the pathophysiology and treatment of depressive disorder. However, data on this issue in bipolar disorder (BD) are limited. The aim of the study was to assess zinc concentrations in the blood serum of patients at various phases and stages of bipolar disorder. METHODS The study included 129 patients with a diagnosis of(More)
BACKGROUND Lowered antioxidant defense systems and increased oxidative stress are implicated in bipolar disorders (BD). Early and late stages of BD may present different biological features (including the level of oxidative stress) and may therefore require different treatment strategies. The aim of this study was to analyze serum levels of lipid(More)
AIM Few scientific reports indicate changes in the concentration of magnesium in the blood of patients with bipolar disorder (BD). So far very little studies concerning these issues have been conducted. Therefore, the aim of this study was to evaluate the serum magnesium level in patients with bipolar disorder (in different phases of the disease) in(More)
Copyright © Polskie Towarzystwo Kardiologiczne INTRODUCTION Depression raises significant public health concerns. According to the National Comorbidity Survey Replication Study, the lifetime prevalence of major depressive disorder (MDD) in the U.S. population is 16.6% [1]. While not included in the MDD’s diagnostic criteria, anxiety is among the three most(More)
The aim of this paper was to review the up-to-date evidence base on pharmacology and clinical properties of lurasidone. Lurasidone is an atypical antipsychotic, approved by the US Food and Drug Administration (FDA) for the treatment of schizophrenia and bipolar depression. Lurasidone exhibits both an antipsychotic and antidepressant action. Based on its(More)
The aim of this paper was to review the up-to-date evidence base on pharmacology and clinical properties of vortioxetine. Vortioxetine is a novel antidepressant, approved by the US Food and Drug Administration (FDA) for the treatment of major depressive disorder (MDD). Because vortioxetine exhibits both an antidepressant and anxiolytic effect, it may be(More)
To examine cytokine receptor biomarkers in bipolar disorder (BD), we recruited 133 well-phenotyped BD patients and 50 normal controls and measured serum levels of soluble interleukin 1 receptor antagonist (sIL-1RA), soluble interleukin-2 receptor (sIL-2R), sIL-6R, and tumor necrosis factor receptor 60 and 80 kDa (sTNFR60/80). sIL-1RA and sTNFR80 are(More)
