Titre : Clinical, developmental and serotonemia phenotyping of a sample of 70 Italian patients with Phelan-McDermid Syndrome Type de document : texte imprimé Auteurs : Lisa ASTA, Auteur ; Arianna RICCIARDELLO, Auteur ; Francesca CUCINOTTA, Auteur ; Laura TURRIZIANI, Auteur ; Maria BONCODDO, Auteur ; Fabiana BELLOMO, Auteur ; Jessica ANGELINI, Auteur ; Martina GNAZZO, Auteur ; Giulia SCANDOLO, Auteur ; Giulia PISANÃ’, Auteur ; Francesco PELAGATTI, Auteur ; Fethia CHEHBANI, Auteur ; Michela CAMIA, Auteur ; Antonio M. PERSICO, Auteur Langues : Anglais (eng) Mots-clés : Humans Male Female Italy Phenotype Child Chromosome Deletion Chromosomes, Human, Pair 22/genetics Adolescent Child, Preschool Adult Young Adult Chromosome Disorders/physiopathology/complications/blood Autism Spectrum Disorder/blood/physiopathology/complications Nerve Tissue Proteins/blood/genetics Intellectual Disability/etiology/blood Shank3 22q13 deletion syndrome Autism spectrum disorder Hyperserotonemia Intellectual disability Macrocephaly Neuroinflammation Phelan-McDermid syndrome Serotonin Index. décimale : PER Périodiques Résumé : BACKGROUND: Phelan-McDermid syndrome (PMS) is caused by monoallelic loss or inactivation at the SHANK3 gene, located in human chr 22q13.33, and is often associated with Autism Spectrum Disorder (ASD). OBJECTIVES: To assess the clinical and developmental phenotype in a novel sample of PMS patients, including for the first time auxometric trajectories and serotonin blood levels. METHODS: 70 Italian PMS patients were clinically characterized by parental report, direct medical observation, and a thorough medical and psychodiagnostic protocol. Serotonin levels were measured in platelet-rich plasma by HPLC. RESULTS: Our sample includes 59 (84.3%) cases with chr. 22q13 terminal deletion, 5 (7.1%) disruptive SHANK3 mutations, and 6 (8.6%) ring chromosome 22. Intellectual disability was present in 69 (98.6%) cases, motor coordination disorder in 65 (92.9%), ASD in 20 (28.6%), and lifetime bipolar disorder in 12 (17.1%). Prenatal and postnatal complications were frequent (22.9%-48.6%). Expressive and receptive language were absent in 49 (70.0%) and 19 (27.1%) cases, respectively. Decreased pain sensitivity was reported in 56 (80.0%), hyperactivity in 49 (80.3%), abnormal sleep in 45 (64.3%), congenital dysmorphisms in 35 (58.3%), chronic stool abnormalities and especially constipation in 29 (41.4%). Parents reported noticing behavioral abnormalities during early childhood immediately after an infective episode in 34 (48.6%) patients. Brain MRI anomalies were observed in 53 (79.1%), EEG abnormalities in 16 (23.5%), kidney and upper urinary tract malformations in 18 (28.1%). Two novel phenotypes emerged: (a) a subgroup of 12/44 (27.3%) PMS patients displays smaller head size at enrollment (mean age 11.8 yrs) compared to their first year of neonatal life, documenting a deceleration of head growth (p < 0.001); (b) serotonin blood levels are significantly lower in 21 PMS patients compared to their 21 unaffected siblings (P < 0.05), and to 432 idiopathic ASD cases (p < 0.001). CONCLUSIONS: We replicate and extend the description of many phenotypic characteristics present in PMS, and report two novel features: (1) growth trajectories are variable and head growth appears to slow down during childhood in some PMS patients; (2) serotonin blood levels are decreased in PMS, and not increased as frequently occurs in ASD. Further investigations of these novel features are under way.

Young autistic children with chronic constipation display higher urinary, and foecal concentrations of p-cresol, an aromatic compound produced by gut bacteria, known to negatively affect brain function. Acute p-cresol administration to BTBR mice enhances anxiety, hyperactivity and stereotypic behaviors, while blunting social interaction. This study was undertaken to prospectively assess the behavioral effects of gut mobilization in young autistic children with chronic constipation, and to verify their possible correlation with urinary p-cresol. To this aim, 21 chronically constipated autistic children 2-8 years old were evaluated before (T0), 1 month (T1), and 6 months (T2) after intestinal mobilization, recording Bristol stool scale scores, urinary p-cresol concentrations, and behavioral scores for social interaction deficits, stereotypic behaviors, anxiety, and hyperactivity. Gut mobilization yielded a progressive and highly significant decrease in all behavioral symptoms over the 6-month study period. Urinary p-cresol levels displayed variable trends not significantly correlated with changes in behavioral parameters, mainly increasing at T1 and decreasing at T2. These results support gut mobilization as a simple strategy to ameliorate ASD symptoms, as well as comorbid anxiety and hyperactivity, in chronically constipated children. Variation in p-cresol absorption seemingly provides limited contributions, if any, to these behavioral changes. Further research will be needed to address the relative role of reduced abdominal discomfort following mobilization, as compared to specific modifications in microbiome composition and in gut bacteria-derived neuroactive compounds.

Despite their widespread use, no evidence-based guidelines are currently available. The aim of this systematic review was to assess the impact of multisensory environment interventions in autism and to provide guidelines. We included all studies of multisensory environment interventions for autistic individuals retrieved from PubMed, Web of Science, and Science Direct up to 30 September 2024. Two researchers appraised the included literature and extracted the data. A total of 1247 unique records were screened for eligibility, and 10 studies were included. Data extraction included demographic characteristics, type of intervention, target symptoms, and outcome measures. Quality assessment tools included the Newcastle-Ottawa Scale and the Cochrane Risk of Bias for randomized controlled trials. The studies were synthesized narratively based on target symptoms. Four studies reported reductions in stereotypic behavior frequency in children and adults; while other studies suggest positive effects on sustained attention, and aggressive and sensory behaviors. Overall, there was insufficient evidence due to the paucity of literature, the significant variation between interventions, and the small sample sizes. Future research should aim to develop a structured intervention approach to address the common limitations of the included designs.Lay abstract Multisensory rooms, also known as multisensory environments, are widely used in clinical practice and schools for autistic people. Despite their widespread use, their usefulness or effectiveness in achieving specific improvements is still unclear. We carry out a comprehensive and systematic quality assessment of all available studies to test the effectiveness of multisensory environment interventions in autism spectrum disorder and to explore what type of targeted intervention is needed to improve both core symptoms and associated features. The results show that multisensory environment could be a useful tool to modulate aggressive and stereotyped behaviors in autistic individuals. Although there is insufficient evidence to conclude on the efficacy of multisensory environment for other types of targets, overall, the results may provide valuable insights for the development of future studies concerning the utility of multisensory environment in therapeutic intervention.

The pathophysiology of TW in ASD is not fully understood. In particular, it is debated whether it may represent a persistent primitive walking pattern or the result of abnormal processing of sensory input from the lower limbs and feet. The present study is aimed at assessing the association between TW and cognitive, sensory, motor and language functions, as well as autism severity. Method We enrolled 112 children and adolescents with ASD, 61 with TW and 51 without TW. A complete psychodiagnostic assessment was performed, including ADOS-2, ADI-R, PEP-3, IQ testing or Griffiths Mental Developmental Scales, and Short Sensory Profile. Results Children and adolescents with TW have significantly lower cognitive level, greater language and motor impairment, as well as greater autism severity. Instead, no difference in severity of sensory abnormalities or in sensory profile emerges between cases with and without TW. Conclusions the present data are most compatible with a model interpreting TW as a behavioral pattern resulting from the persistence of a primitive walking pattern (i.e. lack of heel strike, prior to the acquisition of plantar walking) or possibly of archaic tonic reflexes, rather than as a consequence primarily of abnormal sensory processing. Health practitioners should monitor the gait of autistic children and plan appropriate interventions, aimed at promoting the adoption of more mature plantar walking patterns.
