Developmental functioning and medical Co-morbidity profile of children with complex and essential autism / Jaimie FLOR in Autism Research, 10-8 (August 2017)  

Public ISBD [article]  inAutism Research > 10-8 (August 2017) . - p.1344-1352 Titre : Developmental functioning and medical Co-morbidity profile of children with complex and essential autism Type de document : texte imprimé Auteurs : Jaimie FLOR, Auteur ; Jayne BELLANDO, Auteur ; Maya LOPEZ, Auteur ; Amy SHUI, Auteur Article en page(s) : p.1344-1352 Langues : Anglais (eng) Mots-clés : autism  developmental  children  microcephaly  dysmorphology  essential autism complex autism Index. décimale : PER Périodiques Résumé : Children with Autism Spectrum Disorders (ASD) may be characterized as “complex” (those with microcephaly and/or dysmorphology) or “essential” (those with neither of these two). Previous studies found subjects in the complex group exhibited lower IQ scores, poorer response to behavioral intervention, more seizures and more abnormal EEGs and brain MRIs compared to the essential group. The objective of this study was to determine if there are differences in complex versus essential subjects based on several developmental/psychological measures as well as certain medical comorbidities. This study utilized data from 1,347 individuals (2–17 years old) well-characterized subjects enrolled in Autism Treatment Network (ATN) Registry. Head circumference measurement and the Autism Dysmorphology Measure (ADM) were used by trained physicians to classify subjects as complex or essential. Significantly lower scores were seen for complex subjects in cognitive level, adaptive behavior and quality of life. Complex subjects showed significantly increased physician-documented GI symptoms and were on a higher number of medications. No significant differences in autism severity scores, behavioral ratings and parent-reported sleep problems were found. After adjusting for multiple comparisons made, adaptive scores remained significantly lower for the complex group, and the complex group used a significantly higher number of medications and had increased GI symptoms. Complex and essential autism subtypes may have distinct developmental and medical correlates and thus underlines the importance of looking for microcephaly and dysmorphology, when evaluating a child with autism. Determining this distinction in autism may have implications in prognosis, identifying medical co-morbidities, directing diagnostic evaluations and treatment interventions.

Metabolic Imbalance Associated with Methylation Dysregulation and Oxidative Damage in Children with Autism / Stepan MELNYK in Journal of Autism and Developmental Disorders, 42-3 (March 2012)

Jill JAMES, Auteur Année de publication : 2012 Article en page(s) : p.367-377 Langues : Anglais (eng) Mots-clés : Autism  Oxidative stress  Metabolic  Epigenetics  Glutathione  DNA methylation Index. décimale : PER Périodiques Résumé : Oxidative stress and abnormal DNA methylation have been implicated in the pathophysiology of autism. We investigated the dynamics of an integrated metabolic pathway essential for cellular antioxidant and methylation capacity in 68 children with autism, 54 age-matched control children and 40 unaffected siblings. The metabolic profile of unaffected siblings differed significantly from case siblings but not from controls. Oxidative protein/DNA damage and DNA hypomethylation (epigenetic alteration) were found in autistic children but not paired siblings or controls. These data indicate that the deficit in antioxidant and methylation capacity is specific for autism and may promote cellular damage and altered epigenetic gene expression. Further, these results suggest a plausible mechanism by which pro-oxidant environmental stressors may modulate genetic predisposition to autism.

Retention of autism spectrum disorder diagnosis: The role of co-occurring conditions in males and females / Yen-Tzu WU in Research in Autism Spectrum Disorders, 25 (May 2016)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 25 (May 2016) . - p.76-86 Titre : Retention of autism spectrum disorder diagnosis: The role of co-occurring conditions in males and females Type de document : texte imprimé Auteurs : Yen-Tzu WU, Auteur ; Matthew J. MAENNER, Auteur ; Lisa D. WIGGINS, Auteur ; Catherine E. RICE, Auteur ; Catherine BRADLEY, Auteur ; Maya LOPEZ, Auteur ; Russell S. KIRBY, Auteur ; Li-Ching LEE, Auteur Article en page(s) : p.76-86 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Child sex  Diagnosis retention  Co-occurring conditions (CoCs) Index. décimale : PER Périodiques Résumé : This study examined associations between ASD diagnosis retention and non-ASD co-occurring conditions (CoCs) by child sex. The sample included 7077 males and 1487 females who had an ASD diagnosis documented in their school or health records in a population-based ASD surveillance system for 8-year-old children. ASD diagnosis retention status was determined when an initial ASD diagnosis was not later ruled out by a community professional. We found that ASD diagnosis remains fairly stable, with only 9% of children who had an initial documented ASD diagnosis later being ruled-out. Although most of the associations between the ASD diagnosis retention status and CoCs are similar in both sexes, the co-occurrence of developmental diagnoses (e.g., intellectual disability or sensory integration disorder) was predictive of ASD diagnostic changes in males, whereas the co-occurrence of specific developmental (e.g., personal/social delay) and neurological diagnosis (e.g., epilepsy) was associated with ASD diagnostic change in females. More ASD-related evaluations and less ASD-related impairment were associated with later ASD rule outs in both sexes. Our findings highlight that CoCs can complicate the diagnostic picture and lead to an increased likelihood of ambiguity in ASD diagnosis. Using sensitive and appropriate measures in clinical practice is necessary for differential diagnosis, particularly when there are co-occurring developmental conditions.
