BACKGROUND Treatment with the atypical antipsychotic risperidone can result in elevated prolactin levels. To date, the relationships between plasma concentrations of prolactin, risperidone and its active 9-hydroxy-metabolite have been little investigated in adolescents with psychosis. METHODS Prolactin levels were determined at baseline in 16 hospitalized(More)
Evidence suggests that individuals with posttraumatic stress disorder (PTSD) have an enhanced sensitization of the hypothalamic--pituitary--adrenocortical (HPA) axis. However, few studies in adolescents have been performed. Fourteen sexually abused adolescent inpatients with DSM-IV PTSD (12 female, two male; mean +/- SD age, 16.2 +/- 1.9 years) were(More)
Recent studies suggest that altered serotonergic (5-HT) function, as assessed by lower prolactin (PRL) response to fenfluramine (FEN), a specific 5-HT releaser and uptake inhibitor, is associated with suicidal behavior in either depressed and personality disordered patients. The purpose of this study was to investigate, in schizophrenic patients, the(More)
This study examined the prolactin (PRL), adrenocorticotropin (ACTH) and cortisol responses to the direct DA receptor agonist apomorphine (APO) and the selective 5HT-releasing agent d-fenfluramine (d-FEN) in 20 untreated inpatients with DSM-IV schizophrenia and without a history of suicide attempt, compared to 23 hospitalized healthy controls. We(More)
Depression is both clinically and biologically a heterogeneous entity. Despite advances in psychopharmacology, a significant proportion of depressed patients either continue to have residual symptoms or do not respond to antidepressants. It has therefore become essential to determine parameters (or predictors) that would rationalize the therapeutic choice,(More)
The present study was conducted in order to investigate the relationships between central noradrenergic (NA) and serotonergic (5-HT) function and clinical characteristics of a major depressive episode according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. We measured growth hormone response (ΔGH) to clonidine (CLO) (an α2 NA(More)
BACKGROUND We previously demonstrated that the difference between 2300h and 0800h TSH response to protirelin (TRH) tests on the same day (ΔΔTSH test) is an improved measure in detecting hypothalamic-pituitary-thyroid (HPT) axis dysregulation in depression. This chronobiological index (1) is reduced in about three quarters of major depressed inpatients, and(More)
