A pharmacogenetic study of escitalopram in autism spectrum disorders / Thomas OWLEY in Autism Research, 3-1 (February 2010)
[article]
Titre : A pharmacogenetic study of escitalopram in autism spectrum disorders Type de document : Texte imprimé et/ou numérique Auteurs : Thomas OWLEY, Auteur ; Edwin H. Jr COOK, Auteur ; Bennett L. LEVENTHAL, Auteur ; Camille W. BRUNE, Auteur ; Jeff SALT, Auteur ; Laura WALTON, Auteur ; Steve GUTER, Auteur ; Nelson AYUYAO, Auteur ; Robert D. GIBBONS, Auteur Année de publication : 2010 Article en page(s) : p.1-7 Langues : Anglais (eng) Mots-clés : autistic-disorder escitalopram pharmacogenetics open-label drug-treatment Index. décimale : PER Périodiques Résumé : Objective: To determine the effect of serotonin transporter polymorphism promoter region (5-HTTPLR) genotypic variation (low, intermediate, and high expression groups) on response to escitalopram treatment of children and adolescents with autism spectrum disorders (ASDs). Method: The study used a forced titration, open label design, with genotype blind until study completion. Participants were children and adolescents aged 4-17 years of age with a confirmed ASD (autistic disorder, Asperger's disorder, or pervasive developmental disorder, not otherwise specified). Results: There was an interaction between genotype group and time on the Aberrant Behavior Checklist (ABC) Irritability Subscale (primary outcome variable) (linear maximum marginal likelihood estimation=-4.84, Z=-2.89, SE=1.67, P=0.004). Examination of baseline to last visit revealed that a genotype grouping based on a previous study of platelet 5-HT uptake revealed less response in the genotype group that had S/S genotype for 5-HTTLPR and did not have a diplotype in intron 1 previously shown to be associated with increased platelet 5-HT uptake. Conclusion: This genotype-blind, prospective pharmacogenetic study found the group of subjects with associated with the lowest platelet 5-HT uptake from previous study had the smallest reduction in ABC-Irritability scores after open label treatment with escitalopram. Replication is necessary to confirm these findings. En ligne : http://dx.doi.org/10.1002/aur.109 Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=993
