Stopa depresivnih poremećaja u pandemijskom je porastu. Većinu samoubojstava i pokušaja samoubojstva počine depresivne osobe. Zbog navedenog, neophodni su pouzdani biomarkeri individualizirane procjene rizika suicidalnog ponašanja. Mjerenje koncentracije elemenata u pojedinim biološkim uzorcima omogućuje uvid u promjenu stanja dinamike metabolizma normalnih i patoloških procesa. Metabolički status bioelemenata (BE) te razina hormona i aminokiselina koje sudjeluju u regulaciji metabolizma mogu biti potencijalni biomarkeri suicidalnog ponašanja. Glavni cilj istraživanja bio je ispitati povezanost i međuodnos elektrolita i elemenata u tragovima, aminokiselina i vazopresina u plazmi ispitanika oboljelih od depresije koji su pokušali samoubojstvo (n=38) u odnosu na kontrolnu skupinu (n=47). Istraživanjem nije potvrđena povezanost koncentracije natrija sa suicidalnošću, a rizik za suicid raste sa sniženom ili prosječnom koncentracijom joda (I), litija (Li), povišenom ili prosječnom koncentracijom barija (Ba) kao i s dobi iznad 43,5 godina. Utvrđena je statistički značajno niža koncentracija asparagina kod suicidalne skupine. Potvrđena je obrnuto proporcionalna povezanost vazopresina i suicidalnosti (p<0,001). Dobiveni rezultati mogli bi biti temelj za pronalazak neurospecifičnih biomarkera za depresiju u sklopu personalizirane medicine. Most of the suicides and suicide attempts are result of depressive disorders. Due to a pandemic increase of such disorders, most suicides and suicide attempts are committed by depressive persons, reliable biomarkers of the suicide risk are needed. Measurement of elements concentration in specific biological samples gives us an insight into metabolic dynamic change in normal and pathological processes. Metabolic status of bioelements as well as hormones and amino acids levels could be the biomarkers of suicidal behavior.The aim of research was to analyze concentracions of electrolytes and trace elements, plasma amino acids and vasopressin in depressed hospitalized suicide attempters (n=38) and to correlate the results with those in control subjects (n=47). The main hypothesis of this research was that there is a significant difference in above mentioned parameters between suicide attempters with major depression disorder and healthy control subjects. Significantly higher concentration of sodium (Na) has not been observed in suicide attempter group. Suicide risk increases with decreased or average concentration of iodine (I) and lithium (Li), increased or average concentration of barium (Ba) as well as the age > 43.5 years. We determined significantly decreased concentration of asparagine in suicide attempters. Negative correlation between arginine vasopressin and suicidal behaviour was found (p<0,001). This study could be the basis for potential development of neuro-specific biomarkers in personalized medicine.
