Is there sexual dimorphism of hyperserotonemia in autism spectrum disorder? / Lauren C. SHUFFREY in Autism Research, 10-8 (August 2017)  

Public ISBD [article]  inAutism Research > 10-8 (August 2017) . - p.1417-1423 Titre : Is there sexual dimorphism of hyperserotonemia in autism spectrum disorder? Type de document : Texte imprimé et/ou numérique Auteurs : Lauren C. SHUFFREY, Auteur ; Stephen J. GUTER, Auteur ; Shannon DELANEY, Auteur ; Suma JACOB, Auteur ; George M. ANDERSON, Auteur ; James S. SUTCLIFFE, Auteur ; Edwin H. Jr COOK, Auteur ; Jeremy VEENSTRA-VANDERWEELE, Auteur Article en page(s) : p.1417-1423 Langues : Anglais (eng) Mots-clés : serotonin  5-HT  autism spectrum disorder  hyperserotonemia Index. décimale : PER Périodiques Résumé : Approximately 30% of individuals with autism spectrum disorder (ASD) have elevated whole blood serotonin (5-HT) levels. Genetic linkage and association studies of ASD and of whole blood 5-HT levels as a quantitative trait have revealed sexual dimorphism. Few studies have examined the presence of a sex difference on hyperserotonemia within ASD. To assess whether the rate of hyperserotonemia is different in males than in females with ASD, we measured whole blood 5-HT levels in 292 children and adolescents with ASD, the largest sample in which this biomarker has been assessed. Based upon previous work suggesting that hyperserotonemia is more common prior to puberty, we focused our analysis on the 182 pre-pubertal children with ASD. 42% of pre-pubertal participants were within the hyperserotonemia range. In this population, we found that males were significantly more likely to manifest hyperserotonemia than females (P?=?0.03). As expected, no significant difference was found in the post-pubertal population. Additional work will be needed to replicate this intriguing finding and to understand whether it could potentially explain differences in patterns of ASD risk between males and females.

Intestinal Predictors of Whole Blood Serotonin Levels in Children With or Without Autism / Miranda ZUNIGA-KENNEDY in Journal of Autism and Developmental Disorders, 52-9 (September 2022)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 52-9 (September 2022) . - p.3780-3789 Titre : Intestinal Predictors of Whole Blood Serotonin Levels in Children With or Without Autism Type de document : Texte imprimé et/ou numérique Auteurs : Miranda ZUNIGA-KENNEDY, Auteur ; Micah DAVOREN, Auteur ; Lauren C. SHUFFREY, Auteur ; Ruth Ann LUNA, Auteur ; Tor SAVIDGE, Auteur ; Vinay PRASAD, Auteur ; George M. ANDERSON, Auteur ; Jeremy VEENSTRA-VANDERWEELE, Auteur ; Kent C.

Despite numerous studies investigating the etiology of hyperserotonemia, results have been inconsistent. Recent findings suggest a relationship between the immune system and hyperserotonemia. The current study investigated whether intestinal 5-HT levels, 5-HT gene expression, or intestinal cell types predict WB5-HT. Participants included thirty-one males aged 3-18 who were classified into one of three groups: ASD and functional GI issues, typically developing with GI issues, and typically developing without GI issues. Samples from a lower endoscopy were analyzed to examine the pathways in predicting WB-5HT. Results demonstrated an association between T-Lymphocytes and WB5-HT.

Brief Report: Platelet-Poor Plasma Serotonin in Autism / George M. ANDERSON in Journal of Autism and Developmental Disorders, 42-7 (July 2012)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 42-7 (July 2012) . - p.1510-1514 Titre : Brief Report: Platelet-Poor Plasma Serotonin in Autism Type de document : Texte imprimé et/ou numérique Auteurs : George M. ANDERSON, Auteur ; Margaret E. HERTZIG, Auteur ; P.A. MCBRIDE, Auteur Année de publication : 2012 Article en page(s) : p.1510-1514 Langues : Anglais (eng) Mots-clés : Autism  Serotonin  Hyperserotonemia  Platelet  Platelet-poor plasma (PPP) Index. décimale : PER Périodiques Résumé : Possible explanations for the well-replicated platelet hyperserotonemia of autism include an alteration in the platelet’s handling of serotonin (5-hydroxyserotonin, 5-HT) or an increased exposure of the platelet to 5-HT. Measurement of platelet-poor plasma (PPP) levels of 5-HT appears to provide the best available index of in vivo exposure of the platelet to 5-HT. Mean (±SD) concentrations of PPP 5-HT observed in the autism (N = 18), hyperserotonemic subgroup (N = 5) and control (N = 24) groups were 0.86 ± 0.53, 0.87 ± 0.43 and 0.86 ± 0.36 nM, respectively. The results suggest that the hyperserotonemia of autism is not due to increased exposure of the platelet to 5-HT and make it more likely that the factor(s) contributing to the hyperserotonemia of autism have to do with the platelet’s handling of 5-HT.

Langues : Anglais (eng) Mots-clés : 5-ht  Autism  Hyperserotonemia  Platelet aggregation  Platelet count  Platelet functioning  Platelet release  Serotonin Index. décimale : PER Périodiques Résumé : We comment on the recent report entitled "Platelet Studies in Autism Spectrum Disorder Patients and First-Degree Relatives" [Molecular Autism 2015;6:57]. We find it commendable that the authors have investigated platelet factors potentially involved in the well-replicated observation of platelet hyperserotonemia in autism. However, we believe the results need a fuller discussion in the context of prior studies, think that certain aspects of the interpretation need to be reassessed, and attempt to provide a framework for further research in this area.
