Titre : No relationship between early postnatal testosterone concentrations and autistic traits in 18 to 30-month-old children Type de document : Texte imprimé et/ou numérique Auteurs : Karson T. F. KUNG, Auteur ; M. CONSTANTINESCU, Auteur ; W. V. BROWNE, Auteur ; R. M. NOORDERHAVEN, Auteur ; M. HINES, Auteur Article en page(s) : 15p. Langues : Anglais (eng) Mots-clés : Adult Autism Spectrum Disorder/metabolism/psychology Birth Weight Child Development Child, Preschool Female Humans Infant Male Maternal Age Parents/education Paternal Age Risk Factors Saliva/chemistry Siblings Surveys and Questionnaires Symptom Assessment Testosterone/analysis Autism Gender differences Postnatal development Sex differences Testosterone Index. décimale : PER Périodiques Résumé : BACKGROUND: Some previous research has suggested that testosterone prenatally contributes to gender differences in autistic traits, but little is known about the role of testosterone during early postnatal development (mini-puberty). Two prior studies found no sex difference in testosterone postnatally in saliva samples and detected little to no relationship between testosterone postnatally and autistic traits in toddlers. These findings may reflect late measurements of testosterone at 3 to 4 months of age, after the peak of mini-puberty at 1 to 3 months of age. The present study examined the relationship between testosterone at 1 to 3 months of age and autistic traits at 18 to 30 months of age. FINDINGS: Testosterone was measured in saliva samples collected from children at 1 to 3 months of age. When the children (40 boys, 47 girls) reached 18 to 30 months of age, parents completed the Quantitative Checklist for Autism in Toddlers (Q-CHAT). Boys had higher concentrations of testosterone postnatally and higher Q-CHAT scores than girls. However, testosterone did not correlate with Q-CHAT scores in boys, girls, or the entire sample. CONCLUSIONS: The current results suggest that testosterone during the early postnatal period does not contribute to later autistic traits. Given our relatively small samples and therefore limited power, however, further research could usefully examine if testosterone in saliva samples collected during the peak of mini-puberty in larger groups predicts autistic traits or other traits that show gender differences.

Sex hormones, including testosterone, exert modulatory effects on frontal-limbic brain networks and are associated with emotion dysregulation and depressive symptoms. Weekly changes in hormones predict affective symptoms in peripubertal female adolescents, particularly in the context of stress; however, the biobehavioral mechanisms underlying hormone change and mood relationships during the pubertal transition have yet to be determined and was the objective of the present study. Forty-three peripubertal female adolescents (ages 11-14) collected 8-weekly salivary hormone (estrone, testosterone) samples and mood assessments to evaluate hormone-mood relationships, followed by a biobehavioral testing session with psychosocial stress and EEG. Within-person correlations between weekly hormone changes and corresponding mood were performed to determine individual differences in mood sensitivity to weekly hormone change. Increased frontal theta activity indexing emotion reactivity, reduced cortisol reactivity, and reduced vagal efficiency predicted the strength of the relationship between testosterone and mood. Further, testosterone-sensitivity strength was associated with the enhancement of negative affect following stress testing. Results identify divergent frontal theta and stress responses as potential biobehavioral mechanisms underlying mood sensitivity to peripubertal testosterone fluctuation.

Titre : Developmental vitamin D deficiency increases foetal exposure to testosterone Type de document : Texte imprimé et/ou numérique Auteurs : Asad Amanat ALI, Auteur ; Xiaoying CUI, Auteur ; Renata Aparecida Nedel PERTILE, Auteur ; Xiang LI, Auteur ; Gregory MEDLEY, Auteur ; Suzanne Adele ALEXANDER, Auteur ; Andrew J. O. WHITEHOUSE, Auteur ; John Joseph MCGRATH, Auteur ; Darryl Walter EYLES, Auteur Langues : Anglais (eng) Mots-clés : Animal model Aromatase Autism Developmental vitamin D deficiency Methylation Testosterone Index. décimale : PER Périodiques Résumé : BACKGROUND: Autism spectrum disorder (ASD) is a group of neurodevelopmental disorders which are more common in males. The 'prenatal sex steroid' hypothesis links excessive sex-steroid exposure during foetal life with the behavioural differences observed in ASD. However, the reason why sex steroid exposure may be excessive remains unclear. Epidemiological studies have identified several environmental risk factors associated with ASD, including developmental vitamin D (DVD) deficiency. We have demonstrated in an animal model that DVD-deficiency is associated with a hyper-inflammatory response in placentas from male but not female foetuses. Vitamin D also regulates the expression of several steroidogenic enzymes in vitro. Therefore using this animal model, we have examined whether DVD-deficiency leads to increased sex-steroid levels in both the maternal and foetal compartments. METHODS: Female rats are fed a vitamin D deficient diet from 6 weeks before mating until tissue collection at embryonic day 18. We examined the levels of testosterone, androstenedione and corticosterone in maternal plasma, foetal brains and amniotic fluid. We further examined gene expressions of steroidogenic enzymes and DNA methylation of aromatase promoters in foetal brains as a potential molecular mechanism regulating testosterone expression. RESULTS: We show that DVD-deficiency increases testosterone levels in maternal blood. We also show elevated levels of testosterone and androstenedione in the amniotic fluid of female but not male DVD-deficient foetuses. Testosterone levels were also elevated in DVD-deficient male brains. Vitamin D, like other steroid-related hormones, regulates gene expression via methylation. Therefore we examined whether the significant elevation in testosterone in male brains was due to such a potential gene-silencing mechanism. We show that the promoter of aromatase was hyper-methylated compared to male controls. LIMITATIONS: A reduction in aromatase, in addition to causing excessive testosterone, could also lead to a reduction in estradiol which was not examined here. CONCLUSIONS: This study is the first to show how an epidemiologically established environmental risk factor for ASD may selectively elevate testosterone in male embryonic brains. These findings provide further mechanistic support for the prenatal sex steroid theory of ASD.

Grounded on the dualhormone hypothesis (DHH), which proposes that testosterone (T) is associated with aggressive behavior only when cortisol (C) is low, this study assessed whether the combination of T and C moderated adolescents' aggressive responses to peer victimization. The study involved 577 adolescents (50.4% girls, aged 12-17 years), who completed measures of online and offline victimization and perpetration of aggressive behavior in three waves over the course of one year. Moreover, they provided salivary samples to measure T and C levels. Multilevel analyses showed a three-way interaction between T, C, and victimization levels for both online and offline aggressive behaviors. In both cases, the adolescents with high T and high C or low T and low C responded with more aggressive behaviors when victimized or provoked by peers. The T/C ratio was only associated with aggressive behavior in the girls' sample. The results are opposite to those predicted by the DHH, but they are consistent with the findings of other studies that examined aggressive behaviors as reactions to provocations. These results suggest that some combinations of T and C predict higher aggressive reactions to peer victimization.

Titre : Salivary testosterone in male and female youth with and without autism spectrum disorder: considerations of development, sex, and diagnosis Type de document : Texte imprimé et/ou numérique Auteurs : Rachael A. MUSCATELLO, Auteur ; Emma RAFATJOO, Auteur ; Karan K. MIRPURI, Auteur ; Ahra KIM, Auteur ; Simon VANDEKAR, Auteur ; Blythe A. CORBETT, Auteur Article en page(s) : 37 p. Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder/diagnosis Autistic Disorder Female Humans Longitudinal Studies Male Sexual Development Testosterone Adolescence Androgen Autism Pubertal development Index. décimale : PER Périodiques Résumé : BACKGROUND: Puberty is characterized by significant physical, hormonal, and psychological changes, which may be especially challenging for individuals with autism spectrum disorder (ASD). Although the etiology of ASD remains uncertain, studies suggest imbalances in hormones, such as testosterone, may modulate the autism phenotype. While differences in fetal and postnatal testosterone have been reported, there is limited literature regarding testosterone variations during adolescence in ASD. We investigated morning salivary testosterone levels in youth with ASD and typical development (TD) to explore hypothesized differences, expecting elevated hormonal levels in ASD compared to TD. METHODS: Youth with ASD (n=140) and TD (n=104), ages 10 to 13Â years, were enrolled as part of a longitudinal study on pubertal development. Pubertal stage was determined by gold standard physical examination, and salivary testosterone was collected in the morning immediately upon waking and 30 min after waking and averaged across 3 days. Diagnostic (ASD/TD) and sex (male/female) differences, as well as interactions with age and puberty, were examined using robust linear mixed effect models. RESULTS: Youth with ASD showed significantly elevated testosterone concentrations compared to same-age TD peers. After the inclusion of natural cubic splines to account for nonlinearity in age, a significant age-by-sex interaction emerged with distinct developmental slopes for males and females. At younger ages, females had higher testosterone, until about 11.5Â years of age, when levels began to plateau, while male testosterone concentrations continued to rapidly increase and surpass females. As expected, more advanced pubertal development was associated with elevated testosterone. In contrast, no significant effect of parent-reported social communication symptoms was observed. LIMITATIONS: Limitations include an unequal sex distribution, non-representative sample (e.g., cognition and race/ethnicity), and inability to examine afternoon/evening testosterone due to detection limits. CONCLUSIONS: Testosterone may play a unique role in the presentation of ASD, especially during periods of dynamic hormonal changes including puberty. Inherent developmental (age, puberty) and sex-based (male, female) factors play a more prominent role in changes in testosterone levels during adolescence. Even so, future research is warranted to determine the differential expression and impact of exposure to excess testosterone during the pubertal transition for youth with ASD.
