nutritional status and symptoms in preschool children with autism spectrum disorder a two center comparative study in chongqing and hainan province china
Frontiers in Pediatrics, 2020Co-Authors: Jiang Zhu, Min Guo, Ting Yang, Xi Lai, Ting Tang, Jie ChenAbstract:Objective: The study aimed to compare the nutritional status and symptoms of preschool children with autism spectrum disorder (ASD) from two regions of China, and to analyze the association between nutritional status and symptoms of ASD. Methods: In this cross-sectional study, 738 ASD children and 302 typically developing children (TD) were recruited from Chongqing and Hainan of China. Symptoms of ASD children were evaluated with the Autism Behavior Checklist (ABC), Social Responsiveness Scale (SRS), and Childhood Autism Rating Scale (CARS). Neurodevelopment of ASD children was assessed with the Gesell Developmental Scale (GDS). Nutritional status was evaluated by anthropometric measures, biochemical detection of micronutrients, and providing questionnaire and food frequency questionnaire (FFQ) to caregivers. Results: Comparing ASD children with local TD children, ASD children consumed fewer whole grains, milk and dairy products, beans and soy products, vegetables, and fruits than local TD children in both regions. The serum concentrations of folate, vitamin B12 (VB12), and vitamin D (VD) were consistently lower in ASD children in both regions. Comparing the ASD children between the two regions, the ASD children in Chongqing had significantly higher mean scores of CARS, SRS, and ABC than those in Hainan. The ASD children in Chongqing consumed fewer whole grains, seafood, and fruits than those in Hainan. The serum concentrations of ferritin, vitamin A (VA), VB12, and VD were reduced in the ASD children of Chongqing than those in Hainan, and the ASD children in Chongqing had higher deficiency rates of zinc, ferritin, VA, and VD than those in Hainan. The serum levels of VA, VD, and folate showed a negative association with symptom scores of ASD children. VD and zinc levels had a positive association with the GDS scores of ASD children. Conclusions: ASD children exhibit a higher risk of nutrient deficiencies than neurotypical children, and there are regional differences in the nutritional status of ASD children. Micronutrients VA, VD, folate, and zinc levels were correlated with symptoms and development of ASD children. Therefore, it is essential to provide detailed nutrition evaluation and individualized nutrition interventions for ASD children from different backgrounds.

vitamin a and vitamin d deficiencies exacerbate symptoms in children with autism spectrum disorders
Nutritional Neuroscience, 2019Co-Authors: Min Guo, Jiang Zhu, Ting Yang, Xi Lai, Yuxi Lei, Jie ChenAbstract:Objectives: This study was designed to investigate the vitamin A (VA) and vitamin D (VD) levels in children with autism spectrum disorders (ASD) and to determine whether co-deficiency of VA and VD exacerbates clinical symptoms in autistic children. Methods: The Autism Behavior Checklist, Childhood Autism Rating Scale (CARS), and Social Responsiveness Scale (SRS) were used to assess the symptoms of 332 children diagnosed as ASD. And the Gesell Developmental Scale (GDS) was used to evaluate neurodevelopment in children with ASD. Anthropometric measurement and questionnaire results were compared for all autistic children and 197 age- and gender-matched control children. Serum retinol levels were detected with high-performance liquid chromatography, and serum levels of 25-OH vitamin D were measured with an immunoassay method in the two groups. Results: The ZHA, ZWA, and ZBMIA of the children with ASD were significantly lower than those of the control children. Furthermore, higher proportions of children with picky eating, resistance to new foods, and eating problems were observed in the ASD group when compared with the control group. Serum retinol and 25-OH vitamin D levels in autistic children were significantly lower than those in the control children. Additionally, VA and VD co-deficiency impacts more on the symptoms and development in autistic children. Conclusions: We found that children with autism have more VA and VD deficiencies than control children, and VA and VD co-deficiency may exacerbate the symptoms of children with ASD.

The Italian autism network (ITAN): A resource for molecular genetics and biomarker investigations
'Springer Science and Business Media LLC', 2018Co-Authors: Muglia Pierandrea, Filosi Michele, Da Ros Lucio, Kam-thong Tony, Nardocci Franco, Trabetti Elisabetta, Ratti Emiliangelo, Rizzini Paolo, Zuddas Alessandro, Bernardina, Bernardo DallaAbstract:Background: A substantial genetic component accounts for Autism Spectrum Disorders (ASD) aetiology, with some rare and common genetic risk factors recently identified. Large collections of DNAs from thoroughly characterized ASD families are an essential step to confirm genetic risk factors, identify new variants and investigate genotype-phenotype correlations. The Italian Autism Network aimed at constituting a clinical database and a biorepository of samples derived from ASD subjects and first-degree relatives extensively and consistently characterized by child psychiatry centers in Italy. Methods: The study was approved by the ethical committee of the University of Verona, the coordinating site, and by the local ethical committees of each recruiting site. Certified staff was specifically trained at each site for the overall study conduct, for clinical protocol administration and handling of biological material. A centralized database was developed to collect clinical assessment and medical records from each recruiting site. Children were eligible for recruitment based on the following inclusion criteria: age 4-18 years, at least one parent or legal guardian giving voluntary written consent, meeting DSM-IV criteria for Autistic Disorder or Asperger's Disorder or Pervasive Developmental Disorder NOS. Affected individuals were assessed by full psychiatric, neurological and physical examination, evaluation with ADI-R and ADOS Scales, cognitive assessment with Wechsler Intelligence Scale for Children or Preschool and Primary, Leiter International Performance Scale or Griffiths Mental Developmental Scale. Additional evaluations included language assessment, the Krug Asperger's Disorder Index, and instrumental examination such as EEG and structural MRI. DNA, RNA and plasma were collected from eligible individuals and relatives. A central laboratory was established to host the biorepository, perform DNA and RNA extraction and lymphocytes immortalisation. Discussion: The study has led to an extensive collection of biological samples associated with standardised clinical assessments from a network of expert clinicians and psychologists. Eighteen sites have received ADI/ADOS training, thirteen of which have been actively recruiting. The clinical database currently includes information on 812 individuals from 249 families, and the biorepository has samples for 98% of the subjects. This effort has generated a highly valuable resource for conducting clinical and genetic research of ASD, amenable to further expansion.
