Depression has been associated with various cardiovascular risk factors such as hypertension, obesity, atherogenic dyslipidemia and hyperglycemia. In depressive disorder, hyperactivity of the hypothalamic-pituitary-adrenal (HP A) axis and changes in the immune system have been observed. On the other hand, somatic diseases such as obesity, hyperlipidemia, hypertension and diabetes mellitus type 2 are now perceived as important comorbid conditions in patients
with depression. The pathogenesis of the metabolic syndrome and depression is complex and poorly researched; however, it is considered that the interaction of chronic stress, psychotrauma, hypercotisolism and disturbed immune functions contribute to the development of these disorders. The aim of the study was to investigate the relationship between depression and metabolic syndrome regarding the HP A axis dysfunction and altered inflammatory processes. Literature search in Medline and other databases included articles written in English published between 1985 and 2012. Analysis of the literature was conducted using a systematic approach with the search terms such as depression, metabolic syndrome, inflammation, cytokines, glucocorticoids, cortisol, and HP A axis. In conclusion, the relationship between depression and metabolic syndrome is still a subject of controversy. Further prospective studies are required to clarify the possible causal relationship between depression and metabolic syndrome and its components. Furthermore, it is important to explore the possibility of a common biologic mechanism in the pathogenesis of these two disorders, in which special attention should be paid to the immune system function, especially the possible specific mechanisms by which cytokines can induce and maintain depressive symptoms and metabolic disorders. The data presented here emphasize the importance of recognition and treatment of depressive disorders with consequent reduction in the incidence of metabolic syndrome, but also the need of regular search for metabolic disorders and their treatment to avoid all of these adverse effects and maybe reduce the incidence of depressive disorders.
