Most studies on autism spectrum disorder (ASD) risk factors have been conducted in developed countries where ethnicity and environment are different than in developing countries. We compared nutritional status, immune response and microbiota composition in mestizo children with ASD with matched controls in Ecuador. Twenty-five cases and 35 controls were matched by age, sex and school location. The prevalence of under- and overweight was higher in children with ASD. Nutritional differences were accompanied by abnormal food habits and more frequent gastrointestinal symptoms in children with ASD. Also, greater serum concentrations of TGF-β1 were observed in children with ASD. Finally, there was greater alpha diversity and abundance of (2 OTUs), and different species of in ASD children.

Neurodevelopmental disorders (NDDs) encompass a group of conditions that impact brain development and function, exhibiting significant genetic and clinical heterogeneity. NAA15, the auxiliary subunit of the N-terminal acetyltransferase complex, has garnered attention due to its association with NDDs. However, the precise role of NAA15 in cortical development and its contribution to NDDs remain elusive.

Objective: Autism spectrum disorder (ASD) is a complex neurodevelopmental condition characterized by social communication differences and restricted interests. One proposed biologic mechanism underlying ASD is oxidative stress, leading to the clinical use of glutathione based on anecdotal reports of improved behavior in autistic children. In this pilot study, we tested this observation using a randomized clinical trial format to collect preliminary data on glutathione safety and efficacy.

Many children with ASD exhibit difficulties with emotion regulation that greatly impair functioning. Certain intrinsic correlates of dysregulation have been identified in this population, but the search for potential environmental influences has been less fruitful. The current study examined several aspects of parenting as correlates of observed regulation in Autistic children, as measured in both parent-child and independent regulatory contexts.
