Soluble Interleukin 2 Receptor Levels, Temperament and Character in Formerly Depressed Suicide Attempters Compared With Normal Controls

Soluble interleukin-2 receptor concentrations in plasma were measured & temperament & character profiles & their potential correlation were investigated in formerly depressed patients with a history of suicide attempt. There were no significant differences in soluble interleukin-2 receptor concentrations in plasma between the patient group & age- & gender-matched controls. When compared to controls, suicide attempt patients had a sginificantly higher score on the temperament dimension “harm avoidance” & a lower score on the character dimension “self-directedness”. No significant correlation was found between interleukin values & dimensions on Cloninger’s Temperament & Character Inventory. (47 refs.)
