| Popis: | Pharmacogenetic approach to antidepressant (AD) response is a promising avenue toward individualizing AD treatment. This is particularly relevant in pediatric populations because of concerns about the suicide risk of serotonin selective reuptake inhibitors (SSRIs), resulting in a black-box warning. However, to date, no specific gene or polymorphism has been consistently implicated as a marker of AD side effect (SE) in the pediatric population. The aim of this study was to examine the association between polymorphisms in genes related to the serotonergic system and citalopram SE's in children and adolescents with major depressive disorder (MDD)/dysthymia and/or anxiety disorders. Outpatients (N = 87, 44 % males), aged 7-18 years with a DSM-IV-TR diagnosis of MDD/dysthymia and/or an anxiety disorder were treated in an 8-week open trial with 20-40 mg/day of citalopram. SE's were rated using a questionnaire devised specifically for this study. Association analysis between known/candidate genetic variants in three genes (5-HTR2A, 5-HTR1Dβ, 5-HTR2C) and SE's was conducted. Agitation was more common in boys than girls (male:female 42.1 vs. 18.7 %, χ 2 = 5.61, df = 1, p = 0.018). Subjects with 5-HTR1Dβ CC genotype showed more agitation vs. both CG and GG genotypes (CC:CG:GG 71.4 vs. 33.3 vs. 18.1 %, χ 2 = 8.99, df = 2, p = 0.011). The 5-HTR1Dβ CC genotype was associated with more reports of agitation. It has been suggested that agitation may be an intermediate phenotype to suicidal behavior. Thus, it seems that 5-HTR1Dβ polymorphism may be involved in citalopram-related agitation in children and adolescents treated for depression and/or anxiety. |
