ASD concordance of twins across DSM-IV-TR and DSM-5 diagnostic criteria / Elizabeth P. MCKERNAN in Research in Autism Spectrum Disorders, 41-42 (September 2017)
[article]
Titre : ASD concordance of twins across DSM-IV-TR and DSM-5 diagnostic criteria Type de document : Texte imprimé et/ou numérique Auteurs : Elizabeth P. MCKERNAN, Auteur ; Natalie RUSSO, Auteur ; Courtney BURNETTE, Auteur ; Wendy R. KATES, Auteur Article en page(s) : p.51-56 Langues : Anglais (eng) Mots-clés : Concordance Monozygotic twins DSM-5 Index. décimale : PER Périodiques Résumé : Previous research has supported a high degree of concordance for ASD among monozygotic twins, but no studies have examined concordance rates using DSM-5 diagnostic criteria for ASD. This pilot study examines monozygotic concordance for ASD from the perspective of both DSM-IV-TR and DSM-5 diagnostic criteria. Method Items of the Autism Diagnostic Interview–Revised (ADI-R) and the Autism Diagnostic Observation Schedule (ADOS) were matched to diagnostic criteria (Huerta et al., 2012). Diagnoses were assigned to 14 pairs of monozygotic twins, among whom at least one twin had an autism diagnosis, using DSM-IV-TR and DSM-5 criteria. McNemar tests were performed to determine whether there was a significant difference in sample pairwise concordance rates between the two diagnostic systems. Results Using strict criteria, which required items endorsed from both the ADI-R and the ADOS, eight of the fourteen twin pairs were concordant using DSM-IV-TR criteria compared to five pairs using DSM-5 criteria, yielding pairwise concordance rates of 57.14% and 35.71%, respectively. The use of either the ADI-R or the ADOS (relaxed criteria) resulted in pairwise concordance rates of 85.71% for DSM-IV-TR criteria and 78.57% for DSM-5 criteria. Pairwise concordance rates were not different across DSM-IV-TR and DSM-5 diagnostic criteria using these two methods, but were significantly greater with the use of relaxed as compared to strict criteria for DSM-5. Conclusions In this pilot study, monozygotic pairwise concordance rates were higher for DSM-5 when using information from either the ADI-R or the ADOS, as opposed to both measures.

Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : BACKGROUND: Differences in responding to sensory stimuli, including sensory hyperreactivity (HYPER), hyporeactivity (HYPO), and sensory seeking (SEEK) have been observed in autistic individuals across sensory modalities, but few studies have examined the structure of these "supra-modal" traits in the autistic population. METHODS: Leveraging a combined sample of 3868 autistic youth drawn from 12 distinct data sources (ages 3-18 years and representing the full range of cognitive ability), the current study used modern psychometric and meta-analytic techniques to interrogate the latent structure and correlates of caregiver-reported HYPER, HYPO, and SEEK within and across sensory modalities. Bifactor statistical indices were used to both evaluate the strength of a "general response pattern" factor for each supra-modal construct and determine the added value of "modality-specific response pattern" scores (e.g., Visual HYPER). Bayesian random-effects integrative data analysis models were used to examine the clinical and demographic correlates of all interpretable HYPER, HYPO, and SEEK (sub)constructs. RESULTS: All modality-specific HYPER subconstructs could be reliably and validly measured, whereas certain modality-specific HYPO and SEEK subconstructs were psychometrically inadequate when measured using existing items. Bifactor analyses supported the validity of a supra-modal HYPER construct (?(H)=.800) but not a supra-modal HYPO construct (?(H)=.653), and supra-modal SEEK models suggested a more limited version of the construct that excluded some sensory modalities (?(H)=.800; 4/7 modalities). Modality-specific subscales demonstrated significant added value for all response patterns. Meta-analytic correlations varied by construct, although sensory features tended to correlate most with other domains of core autism features and co-occurring psychiatric symptoms (with general HYPER and speech HYPO demonstrating the largest numbers of practically significant correlations). LIMITATIONS: Conclusions may not be generalizable beyond the specific pool of items used in the current study, which was limited to caregiver report of observable behaviors and excluded multisensory items that reflect many "real-world" sensory experiences. CONCLUSION: Of the three sensory response patterns, only HYPER demonstrated sufficient evidence for valid interpretation at the supra-modal level, whereas supra-modal HYPO/SEEK constructs demonstrated substantial psychometric limitations. For clinicians and researchers seeking to characterize sensory reactivity in autism, modality-specific response pattern scores may represent viable alternatives that overcome many of these limitations.

WAGNER, Auteur ; Samantha DEVITA, Auteur ; Nicole SHEA, Auteur ; Elizabeth P. MCKERNAN, Auteur ; Justin KOPEC, Auteur ; Natalie RUSSO, Auteur ; Frank A. MIDDLETON, Auteur ; Steven D. HICKS, Auteur Article en page(s) : 101788 Langues : Anglais (eng) Mots-clés : Prognosis Biomarkers Saliva RNA microRNA Autism Index. décimale : PER Périodiques Résumé : Background Autism spectrum disorder (ASD) is a complex neurological condition with increasing prevalence. Few tools accurately predict the developmental trajectory of children with ASD. Such tools would allow clinicians to provide accurate prognoses and track the efficacy of therapeutic interventions. Salivary RNAs that reflect the genetic-environmental interactions underlying ASD may provide objective measures of symptom severity and developmental outcomes. This study investigated whether salivary RNAs previously identified in childhood ASD remain perturbed in older children. We also explored whether RNA candidates changed with therapeutic intervention. Method A case-control design was used to characterize levels of 78 saliva RNA candidates among 96 children (48 ASD, 48 non-ASD, mean age: 11 years). Thirty-one children (22 ASD, 9 non-ASD developmental delay, mean age: 4 years) were followed longitudinally to explore changes of RNA candidates during early intervention. Saliva RNA and standardized behavioral assessments were collected for each participant. Associations between candidate RNAs and behavioral scores were determined in both groups via Spearman Correlation. Changes in candidate RNAs across two time-points were assessed in the younger cohort via Wilcoxon rank-sum test. Results Seven RNAs were associated with VABS-II and BASC scores in the older group ([R] >0.25, FDR?0.15). Within the younger cohort, 12 RNAs displayed significant changes over time (FDR?0.05). Three microRNAs were associated with behavioral scores and changed over time (miR-182?5p, miR-146b-5p, miR-374a-5p). Conclusion Several salivary RNAs are strongly associated with autistic behaviors in older individuals with ASD and change as early as three months after therapy initiation in younger children. These molecules could be used to track treatment effectiveness and provide prognoses. Further validation is necessary.
