A lower thyroid-stimulating hormone (TSH) response to thyrotropin-releasing hormone (TRH) in depressed women has been associated with violent suicide attempts, suicidal intent, higher lethality and suicide risk. The cerebrospinal fluid (CSF) 5-hydroxyindoleacetic acid (5-HIAA) and homovanillic acid (HVA) levels are related to suicidal behaviour. We studied the HPT axis function in twelve male suicide attempters and eight healthy volunteers submitted to lumbar puncture and to TRH test. Suicidal behaviour and depression severity were assessed. There was no association between deltamaxTSH and violent suicidality or subsequent suicide. The deltarnaxTSH correlated with CSF HVA in suicide attempters. The plasma T3 showed a negative correlation with the Beck Suicide Intent Scale and the Montgomery Asberg Depression rating scale. Dopaminergic regulatory mechanisms on the thyroid hormone activity may be altered in male suicide attempters. (C) 2008 Elsevier B.V. All rights reserved.
