HOLBROOK, Auteur Article en page(s) : p.137-150 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Early life environments interact with genotype to determine stable phenotypic outcomes. Here we examined the influence of a variant in the brain-derived neurotropic factor (BDNF) gene (Val66Met), which underlies synaptic plasticity throughout the central nervous system, on the degree to which antenatal maternal anxiety associated with neonatal DNA methylation. We also examined the association between neonatal DNA methylation and brain substructure volume, as a function of BDNF genotype. Infant, but not maternal, BDNF genotype dramatically influences the association of antenatal anxiety on the epigenome at birth as well as that between the epigenome and neonatal brain structure. There was a greater impact of antenatal maternal anxiety on the DNA methylation of infants with the methionine (Met)/Met compared to both Met/valine (Val) and Val/Val genotypes. There were significantly more cytosine–phosphate–guanine sites where methylation levels covaried with right amygdala volume among Met/Met compared with both Met/Val and Val/Val carriers. In contrast, more cytosine–phosphate–guanine sites covaried with left hippocampus volume in Val/Val infants compared with infants of the Met/Val or Met/Met genotype. Thus, antenatal Maternal Anxiety × BDNF Val66Met Polymorphism interactions at the level of the epigenome are reflected differently in the structure of the amygdala and the hippocampus. These findings suggest that BDNF genotype regulates the sensitivity of the methylome to early environment and that differential susceptibility to specific environmental conditions may be both tissue and function specific.

Head circumference, body growth and development quotient in autism spectrum disorders are related in Chongqing, China / Hua WEI in Research in Autism Spectrum Disorders, 54 (October 2018)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 54 (October 2018) . - p.83-89 Titre : Head circumference, body growth and development quotient in autism spectrum disorders are related in Chongqing, China Type de document : Texte imprimé et/ou numérique Auteurs : Hua WEI, Auteur ; Qian CHENG, Auteur ; Qixia MEI, Auteur ; Xuan ZHANG, Auteur ; Li CHEN, Auteur ; Xiao LIU, Auteur ; Ying DAI, Auteur ; Ting YU, Auteur ; Yan LI, Auteur ; Yu ZHANG, Auteur ; Jie CHEN, Auteur ; Yongjie MIAO, Auteur ; Tingyu LI, Auteur Article en page(s) : p.83-89 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Head circumference  Body height  Body weight  Development quotient Index. décimale : PER Périodiques Résumé : Background It is unclear whether increased head circumference (HC) is actually an artifact of an overall overgrowth phenomenon or specific to the brain at all in autism spectrum disorders. This study compared the head circumferences, body weight and height of ASD children with a control group. We also discuss whether HC, body weight and height are correlated with development quotients in ASD children. Method We recruited 83 children with ASD (aged 2–5 years); they were gender and age matched to typically developing children in Chongqing (China) from 2013 to 2015. Their head circumference, body weight and height were collected. The ASD group was tested for the developmental quotient (DQ), which includes gross motor, fine motor, linguistic, personal-social and adaptive functioning. Results Our results showed that head circumference in the ASD group is significantly different from HC in the control group. The rate of macrocephaly was higher in the children with ASD compared with the control group. Some domains of DQ have statistically significant negative correlation with head circumference, weight and height. After adjusting for confounding factors, the fine motor was associated negatively with HC. Personal-social ability was associated negatively with weight. Gross motor was correlated negatively with the height. Conclusions Based on our results, we found significant HC differences in ASD group while lack of effect of either height or weight at the age of 2–5. HC, weight and height were separately negative correlated with some domains of development quotients. Further research is needed to understand the relationship between physical indicators and development level in autism.

Intestinal Symptoms Among Children aged 2-7 Years with Autism Spectrum Disorder in 13 Cities of China / Ting YANG in Journal of Autism and Developmental Disorders, 54-11 (November)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 54-11 (November) . - p.4302-4310 Titre : Intestinal Symptoms Among Children aged 2-7 Years with Autism Spectrum Disorder in 13 Cities of China Type de document : Texte imprimé et/ou numérique Auteurs : Ting YANG, Auteur ; Qian ZHANG, Auteur ; Li CHEN, Auteur ; Ying DAI, Auteur ; Fei-Yong JIA, Auteur ; Yan HAO, Auteur ; Ling LI, Auteur ; Jie ZHANG, Auteur ; Li-Jie WU, Auteur ; Xiao-Yan KE, Auteur ; Ming-Ji YI, Auteur ; Qi HONG, Auteur ; Jin-Jin CHEN, Auteur ; Shuan-Feng FANG, Auteur ; Yi-Chao WANG, Auteur ; Qi WANG, Auteur ; Chun-Hua JIN, Auteur ; Jie CHEN, Auteur ; Ting-Yu LI, Auteur Article en page(s) : p.4302-4310 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Background: Autism spectrum disorder (ASD) is a multifactorial, pervasive, neurodevelopmental disorder, of which intestinal symptoms collectively represent one of the most common comorbidities. Methods: In this study, 1,222 children with ASD and 1,206 typically developing (TD) children aged 2-7 years were enrolled from 13 cities in China. Physical measurement and basic information questionnaires were conducted in ASD and TD children. The Childhood Autism Rating Scale (CARS), Social Responsiveness Scale (SRS), and Autism Behavior Checklist (ABC) were used to evaluate the clinical symptoms of children with ASD. The six-item Gastrointestinal Severity Index (6-GSI) was used to evaluate the prevalence of intestinal symptoms in two groups. Results: The detection rates of constipation, stool odor, and total intestinal symptoms in ASD children were significantly higher than those in TD children (40.098% vs. 25.622%, 17.021% vs. 9.287%, and 53.601% vs. 41.294%, respectively). Autistic children presenting with intestinal comorbidity had significantly higher scores on the ABC, SRS, CARS, and multiple subscales than autistic children without intestinal symptoms, suggesting that intestinal comorbidity may exacerbates the core symptoms of ASD children. Conclusion: Intestinal dysfunction was significantly more common in autistic than in TD children. This dysfunction may aggravate the core symptoms of children with ASD.

Methods This study enrolled 1321 children with ASD and 1200 typically developing (TD) children under 7 years old in China. Maternal vitamin supplements were classified for vitamin D, multivitamin (with or without vitamin D), and none (no use of vitamin D or multivitamin). For children with ASD, symptoms were assessed with the Autism Behavior Checklist (ABC), Social Responsiveness Scale (SRS) and Childhood Autism Rating Scale (CARS), and neurodevelopmental levels were evaluated with the Children Neuropsychological and Behavior Scale-Revision 2016 (CNBS-R2016). Results Maternal vitamin D and multivitamin supplementation during pregnancy were both significantly associated with a decreased risk of ASD in offspring (P = 0.024 and P < 0.001). The ASD children born to mothers with gestational multivitamin supplementation had lower CARS [? = ?1.342 (?2.275, ?0.409), P = 0.005] and communication warning behavior [? = ?6.631 (?9.899, ?3.363), P < 0.001] scores and higher personal-social quotient [? = 3.347 (0.190, 6.504), P = 0.038] than children born to mothers without supplementation. Maternal vitamin D supplementation was not associated with symptoms and development quotients in ASD children (P > 0.05). Conclusions This study supports a protective association between maternal vitamin D and multivitamin supplementation during pregnancy and the risk of ASD in offspring. Maternal multivitamin supplementation may potentially moderate the symptoms and personal-social ability in ASD children. Further studies are needed on the role of maternal nutrition in the etiology and autistic symptoms and the underlying molecular mechanisms.
