Titre : Oxytocin levels tend to be lower in autistic children: A meta-analysis of 31 studies Type de document : Texte imprimé et/ou numérique Auteurs : S. JOHN, Auteur ; A. V. JAEGGI, Auteur Article en page(s) : p.2152-2161 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder Autistic Disorder Child Humans Interpersonal Relations Oxytocin/blood autism blood meta-analysis oxytocin oxytocin levels plasma saliva serum Index. décimale : PER Périodiques Résumé : Oxytocin is a hormone that mediates interpersonal relationships through enhancing social recognition, social memory, and reducing stress. It is released centrally into the cerebrospinal fluid, as well as peripherally into the blood, where it can easily be measured. Some studies indicate that the oxytocin system with its social implications might be different in people with autism spectrum disorder. With summarizing evidence of 31 studies, this meta-analysis suggests that children with autism spectrum disorder have lower blood oxytocin levels compared to neurotypical individuals. This might not be the case for adults with autism spectrum disorder, where we could not find a difference. Our findings motivate further exploration of the oxytocin system in children with autism spectrum disorder. This could lead to therapeutic options in treating autism spectrum disorder in childhood.

Titre : Oxytocin impacts top-down and bottom-up social perception in adolescents with ASD: a MEG study of neural connectivity Type de document : Texte imprimé et/ou numérique Auteurs : Adi KORISKY, Auteur ; Ilanit GORDON, Auteur ; Abraham GOLDSTEIN, Auteur Article en page(s) : 36 p. Langues : Anglais (eng) Mots-clés : Administration, Intranasal Animals Autistic Disorder/diagnostic imaging/drug therapy Double-Blind Method Facial Recognition/physiology Magnetic Resonance Imaging/methods Oxytocin/pharmacology Social Perception Autism Connectivity Face perception Gamma Meg Oxytocin personal or financial interests that could influence the study in this paper. Index. décimale : PER Périodiques Résumé : BACKGROUND: In the last decade, accumulative evidence has shown that oxytocin can modulate social perception in typically developed individuals and individuals diagnosed with autism. While several studies show that oxytocin (OT) modulates neural activation in social-related neural regions, the mechanism that underlies OT effects in ASD is not fully known yet. Despite evidence from animal studies on connections between the oxytocinergic system and excitation/inhibition neural balance, the influence of OT on oscillatory responses among individuals with ASD has been rarely examined. To bridge these gaps in knowledge, we investigated the effects of OT on both social and non-social stimuli while focusing on its specific influence on the neural connectivity between three socially related neural regions-the left and right fusiform and the medial frontal cortex. METHODS: Twenty-five adolescents with ASD participated in a wall-established social task during a randomized, double-blind placebo-controlled MEG and OT administration study. Our main task was a social-related task that required the identification of social and non-social-related pictures. We hypothesized that OT would modulate the oscillatory connectivity between three pre-selected regions of interest to be more adaptive to social processing. Specifically, we focused on alpha and gamma bands which are known to play an important role in face processing and top-down/bottom-up balance. RESULTS: Compared to placebo, OT reduced the connectivity between the medial frontal cortex and the fusiform in the low gamma more for social stimuli than for non-social ones, a reduction that was correlated with individuals' performance in the task. Additionally, for both social and non-social stimuli, OT increased the connectivity in the alpha and beta bands. LIMITATIONS: Sample size was determined based on sample sizes previously reported in MEG in clinical populations, especially OT administration studies in combination with neuroimaging in ASD. We were limited in our capability to recruit for such a study, and as such, the sample size was not based on a priori power analysis. Additionally, we limited our analyses to specific neural bands and regions. To validate the current results, future studies may be needed to explore other parameters using whole-brain approaches in larger samples. CONCLUSION: These results suggest that OT influenced social perception by modifying the communication between frontal and posterior regions, an attenuation that potentially impacts both social and non-social early perception. We also show that OT influences differ between top-down and bottom-up processes, depending on the social context. Overall, by showing that OT influences both social-related perception and overall attention during early processing stages, we add new information to the existing understanding of the impact of OT on neural processing in ASD. Furthermore, by highlighting the influence of OT on early perception, we provide new directions for treatments for difficulties in early attentional phases in this population.

Titre : Oxytocin in the Developing Brain: Relevance as Disease-Modifying Treatment in Autism Spectrum Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Bice CHINI, Auteur ; Marianna LEONZINO, Auteur ; Valentina GIGLIUCCI, Auteur Année de publication : 2016 Importance : p.253-266 Langues : Anglais (eng) Mots-clés : Autism Monoamines Neurodevelopment Opioid Oxytocin Oxytocin receptor Perinatal treatment Social behavior Index. décimale : SCI-D SCI-D - Neurosciences Résumé : Among the several neurobiological systems implicated in shaping social behavior, oxytocin (OXT) has been firmly established as a master regulator of the social brain. This has led OXT to be proposed as a drug to ameliorate social deficits in a number of neurodevelopmental and neuropsychiatric conditions including autism spectrum disorders (ASDs). OXT administration has indeed been shown to improve social symptoms in adult ASD patients; even more interestingly, OXT has been shown to regulate key neurodevelopmental events, which suggests that the peptide can modify the onset and progression of ASD symptoms in childhood. We will review here the anatomical and neurochemical basis of these actions, with a special emphasis on the interactions of OXT with other key neurotransmitter systems involved in the regulation of social behavior at the early postnatal developmental stages.

There are no conflicts of interest. Index. décimale : PER Périodiques Résumé : BACKGROUND: Oxytocin is expected as a novel therapeutic agent for autism spectrum disorder (ASD) core symptoms. However, previous results on the efficacy of repeated administrations of oxytocin are controversial. Recently, we reported time-course changes in the efficacy of the neuropeptide underlying the controversial effects of repeated administration; however, the underlying mechanisms remained unknown. METHODS: The current study explored metabolites representing the molecular mechanisms of oxytocin's efficacy using high-throughput metabolomics analysis on plasma collected before and after 6-week repeated intranasal administration of oxytocin (48 IU/day) or placebo in adult males with ASD (N?=?106) who participated in a multi-center, parallel-group, double-blind, placebo-controlled, randomized controlled trial. RESULTS: Among the 35 metabolites measured, a significant increase in N,N-dimethylglycine was detected in the subjects administered oxytocin compared with those given placebo at a medium effect size (false discovery rate (FDR) corrected P?=?0.043, d?=?0.74, N?=?83). Furthermore, subgroup analyses of the participants displaying a prominent time-course change in oxytocin efficacy revealed a significant effect of oxytocin on N,N-dimethylglycine levels with a large effect size (P(FDR)?=?0.004, d?=?1.13, N?=?60). The increase in N,N-dimethylglycine was significantly correlated with oxytocin-induced clinical changes, assessed as changes in quantifiable characteristics of autistic facial expression, including both of improvements between baseline and 2 weeks (P(FDR)?=?0.006, r?=?-?0.485, N?=?43) and deteriorations between 2 and 4 weeks (P(FDR)?=?0.032, r?=?0.415, N?=?37). LIMITATIONS: The metabolites changes caused by oxytocin administration were quantified using peripheral blood and therefore may not directly reflect central nervous system changes. CONCLUSION: Our findings demonstrate an association of N,N-dimethylglycine upregulation with the time-course change in the efficacy of oxytocin on autistic social deficits. Furthermore, the current findings support the involvement of the N-methyl-D-aspartate receptor and neural plasticity to the time-course change in oxytocin's efficacy.

In the current study, gene-environment interaction between OXTR and prenatal exposure to either OT or OXTR antagonist (OXTRA) in predicting early social communication development was examined. One hundred and fifty-three children (age: M = 4.32, SD = 1.07) were assigned to four groups based on prenatal history: children whose mothers prenatally received OXTRA and Nifedipine to delay preterm labor (n = 27); children whose mothers received Nifedipine only to delay preterm labor (n = 35); children whose mothers received OT for labor augmentation (n = 56), and a no intervention group (n = 35). Participants completed a developmental assessment of intelligence quotient (IQ), adaptive behavior, and social communication abilities. DNA was extracted via buccal swab. A genetic risk score was calculated based on four OXTR single nucleotide polymorphisms (rs53576, rs237887, rs1042778, and rs2254298) previously reported to be associated with ASD symptomatology. OXTRrisk-allele dosage was associated with more severe autism diagnostics observation schedule (ADOS) scores only in the OXTRA group. In contrast, in the Nifedipine, OT, and no intervention groups, OXTRrisk-allele dosage was not associated with children's ADOS scores. These findings highlight the importance of both genetic and environmental pathways of OT in signaling early social development and raise the need for further research in this field. Autism Res 2019, 12: 1087-1100. (c) 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: In the current study, we examined if the association between prenatal exposure to an oxytocin receptor antagonist (OXTRA) and autism spectrum disorder (ASD) related impairments are dependent on an individual's genetic background for the oxytocin receptor gene (OXTR). Children who carried a greater number of risk alleles for the OXTR gene and whose mothers received OXTRA to delay preterm labor showed more ASD-related impairments. The results highlight the importance of both genetic and environmental pathways of oxytocin in shaping early social development.
