title: TSH-response patterns to TRH stimulation may indicate therapeutic mechanisms of antidepressant and neuroleptic drugs.
abstract: The study was designed to investigate, by weekly thyrotropin-releasing hormone tests, possible patterns of thyroid-stimulating hormone (TSH) responses which may indicate therapeutic mechanisms of antidepressant and neuroleptic drugs in patients with depressive and paranoid-hallucinatory syndrome during their process of recovery (3-9 weeks). 65 depressed women and 33 paranoid-hallucinatory women have been studied while on antidepressant (clomipramine) or neuroleptic (haloperidol) treatment, respectively. Four patterns of TSH response were observed. Patients with a pattern of a 'disblunting TSH response' (normalization of an abnormal low response) during drug treatment had a significantly higher chance to recover compared to patients with other TSH response patterns. This finding was independent of psychopathological features and drugs used for treatment. A hypothesis of 'malactivation' as a pathogenetic indicator of various psychotic states is being presented.
