This study aimed to investigate the gut metabolomic profiles of autistic children and to analyze potential interaction between gut metabolites with autistic symptoms and neurodevelopment levels. We involved 120 autistic and 60 neurotypical children. Autistic symptoms and neurodevelopment levels were assessed. Fecal samples were analyzed using untargeted liquid chromatography-tandem mass spectrometry methods. Our results showed the metabolic disturbances of autistic children involved in multiple vitamin and amino acid metabolism pathways, with the strongest enrichment identified for tryptophan metabolism, retinol metabolism, cysteine-methionine metabolism, and vitamin digestion and absorption. Differential gut metabolites were correlated to autistic symptoms and neurodevelopment levels. Our findings improved the understanding of the perturbations of metabolome networks in autism.

Causal Network Analysis Reveals Key Brain Regions Associated With Severity in Children With Autism Spectrum Disorder / Xiaofen SUN in Autism Research, 18-9 (September 2025)

We examined 113 ASD children aged 2 8 years (17 mild cases, 56 moderate cases, and 40 severe cases), as well as 110 age and sex-matched healthy controls (HC). Voxel-based morphometry (VBM) was used to compare GM density (GMD) changes between ASD and HC groups. Additionally, structural covariance network analysis quantified the cross-regional synchronous changes in GM among ASD children, and causal analysis described the pattern of changes in the GM network related to symptom severity in ASD children. The results indicated that ASD children exhibiting mild symptoms have an enlarged parahippocampal gyrus, and as the severity of ASD increases, the range of GMD changes expands (p=0.05, FDR correction). Granger causality (GC) analysis revealed that the parahippocampal gyrus may function as a central hub within ASD-related directional networks, exerting causal effects on other brain regions (p=0.05). These findings were validated by external datasets. Our results provide preliminary insights into the role of the parahippocampal gyrus in ASD and promote the application of dimensional models.

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 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.
