Oxytocin plasma levels in psychiatric patients with and without recent suicide attempt

Abstract

Easily available biomarkers for suicidality would be valuable for the identification of individuals at risk. Oxytocin has been shown to be associated with mental illness. We assessed basal oxytocin plasma levels of patients with (SA, n=41) and without (NSA, n=40) a 1-year history of attempted suicide. SA and NSA groups did not differ with respect to oxytocin levels. Plasma oxytocin may not be a biological suicide marker candidate.
