Severity of ASD symptoms and their correlation with the presence of copy number variations and exposure to first trimester ultrasound / Sara Jane WEBB in Autism Research, 10-3 (March 2017)
[article]
Titre : Severity of ASD symptoms and their correlation with the presence of copy number variations and exposure to first trimester ultrasound Type de document : Texte imprimé et/ou numérique Auteurs : Sara Jane WEBB, Auteur ; Michelle M. GARRISON, Auteur ; Raphael BERNIER, Auteur ; Abbi M. MCCLINTIC, Auteur ; Bryan H. KING, Auteur ; Pierre D. MOURAD, Auteur Article en page(s) : p.472-484 Langues : Anglais (eng) Mots-clés : epidemiology genetics environmental influences ASD severity ultrasound Index. décimale : PER Périodiques Résumé : Current research suggests that incidence and heterogeneity of autism spectrum disorder (ASD) symptoms may arise through a variety of exogenous and/or endogenous factors. While subject to routine clinical practice and generally considered safe, there exists speculation, though no human data, that diagnostic ultrasound may also contribute to ASD severity, supported by experimental evidence that exposure to ultrasound early in gestation could perturb brain development and alter behavior. Here we explored a modified triple hit hypothesis [Williams & Casanova, ] to assay for a possible relationship between the severity of ASD symptoms and (1) ultrasound exposure (2) during the first trimester of pregnancy in fetuses with a (3) genetic predisposition to ASD. We did so using retrospective analysis of data from the SSC (Simon's Simplex Collection) autism genetic repository funded by the Simons Foundation Autism Research Initiative. We found that male children with ASD, copy number variations (CNVs), and exposure to first trimester ultrasound had significantly decreased non-verbal IQ and increased repetitive behaviors relative to male children with ASD, with CNVs, and no ultrasound. These data suggest that heterogeneity in ASD symptoms may result, at least in part, from exposure to diagnostic ultrasound during early prenatal development of children with specific genetic vulnerabilities. These results also add weight to on-going concerns expressed by the FDA about non-medical use of diagnostic ultrasound during pregnancy.

Titre : Maternal beliefs about autism: A link between intervention services and autism severity in White and Latino mothers Type de document : Texte imprimé et/ou numérique Auteurs : Nuri M. REYES, Auteur ; Olivia J. LINDLY, Auteur ; Alison E. CHAVEZ, Auteur ; Ann FOLAN, Auteur ; Kristy MACIAS, Auteur ; Kathryn A. SMITH, Auteur ; Ann REYNOLDS, Auteur ; Katharine E. ZUCKERMAN, Auteur Article en page(s) : p.38-48 Langues : Anglais (eng) Mots-clés : Autism Maternal beliefs about ASD Children ASD severity Intervention services use Index. décimale : PER Périodiques Résumé : Variation in parental beliefs about Autism Spectrum Disorder (ASD) may impact subsequent service use profiles. This study aimed to examine (1) variation in beliefs about ASD among English language proficient White (EP-W) mothers, English language proficient Latino (EPL) mothers, and limited English language proficient Latino (LEP-L) mothers of children with ASD; (2) variation in beliefs about ASD in the context of the child's ASD severity, among EP White mothers, EP Latino others, and LEP Latino mothers; and (3) potential links between maternal beliefs about ASD and children's current ASD treatment. This multi-site study included 305 English or Spanish-speaking parents of children with ASD, ages 2–10 years, who completed a survey about their beliefs about their child's ASD, their child's ASD severity, and treatments used by their children. Results showed that mothers in the EP-W, EP-L, and LEP-L groups differed in their beliefs about viewing ASD as a mystery. Only maternal views of ASD severity in the EP-W group were linked to their beliefs about ASD. Finally, maternal beliefs about ASD having major consequences on their child's life, and ASD being a mystery were strongly associated with a child's use of ASD intervention services. These findings provide new knowledge of how maternal beliefs about ASD vary in linguistically diverse groups, how a child's ASD severity may influence such beliefs, and how maternal beliefs correlate with the amount of therapy children with ASD receive. Future research should address how these beliefs or views are formed, what factors influence them, or whether they are malleable. Understanding parents' beliefs or views of having a child with ASD can potentially help us increase use of ASD intervention services in families of children with ASD.

Titre : Are Urinary Porphyrins a Valid Diagnostic Biomarker of Autism Spectrum Disorder? Type de document : Texte imprimé et/ou numérique Auteurs : Kerrie SHANDLEY, Auteur ; David W. AUSTIN, Auteur ; Jahar L. BHOWMIK, Auteur Article en page(s) : p.535-542 Langues : Anglais (eng) Mots-clés : porphyrins biomarker ASD diagnosis ASD severity heavy metals mercury Index. décimale : PER Périodiques Résumé : A fundamental challenge to the timely diagnosis of Autism Spectrum Disorder (ASD) is the reliance on the observation of a set of aberrant behavior. Consequently, the diagnostic process requires that the child reach an age where the behaviors would typically be exhibited. The identification of a reliable biological marker (biomarker) could be of considerable benefit to the diagnostic process. As a diagnostic biomarker, porphyrins present an attractive prospect as previous studies have reported consistent findings of children with ASD showing significant elevations in porphyrin levels in contrast to controls. Furthermore, there is some evidence that ASD severity may be associated with porphyrins, which would be a valuable characteristic of any ASD biomarker. Importantly, for practical use, porphyrins can be tested non-invasively via a sample of urine. The present study sought to investigate whether porphyrin profiles can reliably be used to (a) differentiate ASD cases from healthy controls; and (b) predict ASD severity. The study compared the porphyrin levels of three groups of children aged 2–6 years: Group 1—children diagnosed with ASD (n?=?70); Group 2—healthy, normally developing siblings of children diagnosed with ASD (n?=?36); and Group 3—healthy, normally developing children with no known blood relative diagnosed with ASD (n?=?54). The results of logistic regression analyses failed to find support for the hypotheses that porphyrin levels could be used as a valid tool to detect ASD cases or predict severity.
