Autism and Phthalate Metabolite Glucuronidation / T. Peter STEIN in Journal of Autism and Developmental Disorders, 43-11 (November 2013)

[article]
Titre : Autism and Phthalate Metabolite Glucuronidation Type de document : Texte imprimé et/ou numérique Auteurs : T. Peter STEIN, Auteur ; Margaret D. SCHLUTER, Auteur ; Robert A. STEER, Auteur ; Xue MING, Auteur Article en page(s) : p.2677-2685 Langues : Anglais (eng) Mots-clés : Diethylhexyl phthalate Phthalates Autism Glucuronidation Index. décimale : PER Périodiques Résumé : Exposure to environmental chemicals may precipitate autism spectrum disorders (ASD) in genetically susceptible children. Differences in the efficiency of the glucuronidation process may substantially modulate substrate concentrations and effects. To determine whether the efficiency of this pathway is compromised in children with ASD, we measured the efficiency of glucuronidation for a series of metabolites derived from the commonly used plasticizer, diethylhexyl phthalate. Spot urines were collected and analyzed for the fraction of each metabolite conjugated by isotope dilution-liquid chromatography mass spectrometry-mass spectrometry. The degree of glucuronidation was lower with the ASD group. The glucuronidation pathway may differ in some children with ASD.

Titre : BDI-2 - Inventaire de dépression de Beck Type de document : Texte imprimé et/ou numérique Auteurs : Aaron T. BECK, Auteur ; Robert A. STEER, Auteur ; Gregory K. BROWN, Auteur Mention d'édition : 2ème édition Editeur : Paris [France] : ECPA - Editions du Centre de Psychologie Appliquée Année de publication : 1998 ISBN/ISSN/EAN : 978-2-902656-45-5 Langues : Français (fre) Index. décimale : OUT-A OUT-A - Outils d‘Evaluation - Tests Résumé : L'auteur du questionnaire d’auto-évaluation de la dépression (BDI), A.T. Beck, est connu pour ses travaux de pionnier sur le modèle cognitif de la dépression et sur l’application de ce modèle à la psychothérapie.
Construit sur la base des critères diagnostiques des troubles dépressifs du DSM-IV, cet inventaire permet de mesurer la sévérité de la dépression et de préciser la nature des troubles. Ce test propose deux étalonnages : "population tout-venant" et "population psychiatrique". D'une grande rapidité de passation et de correction, le BDI II est une référence internationale en matière d'évaluation de la dépression.

Titre : Bisphenol A Exposure in Children With Autism Spectrum Disorders Type de document : Texte imprimé et/ou numérique Auteurs : T. Peter STEIN, Auteur ; Margaret D. SCHLUTER, Auteur ; Robert A. STEER, Auteur ; Lining GUO, Auteur ; Xue MING, Auteur Article en page(s) : p.272-283 Langues : Anglais (eng) Mots-clés : bisphenol A (BPA) autism spectrum disorders glucuronidation phthalates plasticizers Index. décimale : PER Périodiques Résumé : The etiology of autism spectrum disorders (ASD) is believed to involve genetic and environmental components. This study focused on the plasticizer, Bisphenol-A (BPA). The major pathway for BPA metabolism and excretion is via glucuronidation. To determine whether there was a relationship between BPA exposure and ASD, urine specimens were collected from 46 children with ASD and 52 controls. Free and total BPA concentrations were determined by mass spectrometry. The fraction glucuronidated was calculated from the difference. A metabolomics study was done to investigate metabolite distribution in the urine. (i) Most of the BPA excreted in the urine was as the glucuronide; (ii) about 20% of the ASD children had BPA levels beyond the 90th percentile (>50 ng/mL) of the frequency distribution for the total sample of 98 children; (iii) Mann–Whitney U tests and multiple regression analyses found significant differences (P?0.05) between the groups in total and % bound BPA; and (iv) the metabolomics analyses showed the number of absolute partial correlations >|0.30| between metabolite concentrations and total BPA was ?3 times greater with the ASD group than the controls (P?0.001), and the number of absolute partial correlations?>?|0.30| for % bound BPA was ?15 times higher with ASD (P?0.001). The results suggest there is an association between BPA and ASD.
