The current study was designed to replicate and expand a recent report in this Journal (McDonnell et al. in J Autism Dev Disord 49:1391 1401, https://doi.org/10.1080/15374416.2020.1823850, 2019), in which only 60% of diagnoses were made with complete certainty by clinicians evaluating 478 toddlers and preschool children referred for possible ASD to specialized clinics. In this study, secondary analyses were performed on diagnostic, demographic and clinical data for 496 16 30-month-old children who were consecutive referrals to a 6-site clinical trial executed by specialized centers with experienced clinicians following best-practice procedures for the diagnosis of ASD. Overall, 70.2% of diagnoses were made with complete certainty. The most important factor associated with clinician uncertainty was mid-level autism-related symptomatology. Mid-level verbal age equivalents were also associated with clinician uncertainty, but measures of symptomatology were stronger predictors. None of the socio-demographic variables, including sex of the child, was significantly associated with clinician certainty. Close to one third of early diagnoses of ASD are made with a degree of uncertainty. The delineation of specific ranges on the ADOS-2 most likely to result in clinician uncertainty identified in this study may provide an opportunity to reduce random subjectivity in diagnostic decision-making via calibration of young-child diagnostic thresholds based on later-age longitudinal diagnostic outcome data, and via standardization of decision-making in regard to clinical scenarios frequently encountered by clinicians.

GREGORY, Auteur Article en page(s) : p.502-523 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Oxytocin (OT), the brain's most abundant neuropeptide, plays an important role in social salience and motivation. Clinical trials of the efficacy of OT in autism spectrum disorder (ASD) have reported mixed results due in part to ASD's complex etiology. We investigated whether genetic and epigenetic variation contribute to variable endogenous OT levels that modulate sensitivity to OT therapy. To carry out this analysis, we integrated genome-wide profiles of DNA-methylation, transcriptional activity, and genetic variation with plasma OT levels in 290 participants with ASD enrolled in a randomized controlled trial of OT. Our analysis identified genetic variants with novel association with plasma OT, several of which reside in known ASD risk genes. We also show subtle but statistically significant association of plasma OT levels with peripheral transcriptional activity and DNA-methylation profiles across several annotated gene sets. These findings broaden our understanding of the effects of the peripheral oxytocin system and provide novel genetic candidates for future studies to decode the complex etiology of ASD and its interaction with OT signaling and OT-based interventions. Lay Summary Oxytocin (OT) is an abundant chemical produced by neurons that plays an important role in social interaction and motivation. We investigated whether genetic and epigenetic factors contribute to variable OT levels in the blood. To this, we integrated genetic, gene expression, and non-DNA regulated (epigenetic) signatures with blood OT levels in 290 participants with autism enrolled in an OT clinical trial. We identified genetic association with plasma OT, several of which reside in known autism risk genes. We also show statistically significant association of plasma OT levels with gene expression and epigenetic across several gene pathways. These findings broaden our understanding of the factors that influence OT levels in the blood for future studies to decode the complex presentation of autism and its interaction with OT and OT-based treatment.

Pivotal Response Group Treatment Program for Parents of Children with Autism / Mendy B. MINJAREZ in Journal of Autism and Developmental Disorders, 41-1 (January 2011)

Research has demonstrated that parent-delivered behavioral interventions are a viable treatment model; however, little research has focused on teaching parents in groups. The aim of this study was to demonstrate that parents can learn Pivotal Response Training (PRT) in group therapy, resulting in correlated gains in children’s language. Baseline and post-treatment data were obtained and examined for changes in (a) parent fidelity of PRT implementation, and (b) child functional verbal utterances. Significant differences were observed for both variables. These findings suggest that parents can learn PRT in a group format, resulting in correlated child language gains, thus future controlled studies are warranted.

Families who completed the active treatment (N = 23) were followed for an additional 12 weeks to measure changes in language and cognitive skills. Results indicated a significant improvement in frequency of functional utterances, with maintenance at 3-month follow-up [F(2, 21): 5.9, p = .009]. Children also made significant gains on the Vineland Communication Domain Standard Score [F(2, 12):11.74, p = .001] and the Mullen Scales of Early Learning Composite score [F(1, 20) = 5.43, p = .03]. These results suggest that a brief PRT parent group intervention can lead to improvements in language and cognitive functioning that are maintained 12 weeks post treatment.
