[I-123] ADAM and SPECT in patients with borderline personality disorder and healthy control subjects
Abstract
Objective: Serotonergic dysfunction is considered to be involved in the pathophysiology of borderline personality disorder (BPD). The aim of this study was to investigate serotonin transporter availability in patients with BPD as a marker of the central serotonergic system.
Methods: Eight unmedicated patients with BPD and 9 healthy control subjects received single photon emission computed tomography (SPECT) 4 hours after injection of 185 MBq [I-123] ADAM (2-([2-([dimethylamino]methyl)phenyl]thio)). As a measure of brain serotonin transporter (SERT) availability, ratios of specific-to-nonspecific [I-123] ADAM binding for the brainstem and hypothalamus were calculated with an occipital reference. Levels of impulsiveness and depressive symptoms were assessed with the Barratt Impulsiveness Scale and the Beck Depression Inventory.
Results: Mean specific-to-nonspecific ratios showed a 43% higher brainstem and a 12% higher hypothalamus ADAM binding in patients, compared with control subjects. We found significant correlations of ADAM binding with both age and impulsiveness but not depression. Associations of BIS scores with ADAM binding remained significant after controlling for age and depression (r = 0.69, p < 0.01).
Conclusion: The study provides evidence of a serotonergic dysfunction in patients with BPD and suggests a serotonergic component in the pathophysiology of the disorder. SERT binding reflected the level of impulsiveness as a common feature in BPD.
Objectif: On considère que le dysfonctionnement sérotoninergique joue un rôle dans la pathophysiologie du trouble de personnalité limite (TPL). Cette étude visait à étudier, chez les patients atteints d'un TPL, la disponibilité du transporteur de la sérotonine comme marqueur du système sérotoninergique central.
Méthodes: Huit patients atteints d'un TPL qui ne prenaient pas de médicament et neuf sujets témoins en bonne santé ont été soumis à une tomographie d'émission monophotonique (TEM) 4 heures après avoir reçu par injection 185 MBq [I-123] d'ADAM (2-([2-([dimethylamino]methyl)phenyl]thio)). Pour mesurer la disponibilité du transporteur de la sérotonine dans le cerveau (SERT), on a calculé des ratios de fixation spécifique:non spécifique [I-123] d'ADAM dans le tronc cérébral et l'hypothalamus en utilisant un point de référence occipital. On a évalué les niveaux d'impulsivité et de symptômes dépressifs au moyen de l'échelle d'impulsivité de Barratt (EIB) et du questionnaire de dépression de Beck.
Résultats: Les ratios de fixation spécifique:non spécifique moyens ont montré que la fixation de l'ADAM était plus élevée de 43 % dans le tronc cérébral et de 12 % dans l'hypothalamus chez les patients comparativement aux sujets témoins. Nous avons constaté des liens importants entre la fixation de l'ADAM et à la fois l'âge et l'impulsivité, mais non la dépression. Les liens entre les résultats de l'EIB et la fixation de l'ADAM sont demeurés importants compte tenu de l'âge et de la dépression (r = 0,69, p < 0,01).
Conclusion: L'étude présente des preuves de dysfonctionnement sérotoninergique chez les patients atteints de TPL et indique la présence d'un élément sérotoninergique dans la pathophysiologie du trouble. La fixation du SERT reflète le niveau d'impulsivité, caractéristique très commune dans les cas de TPL.
