Background Autism spectrum disorders (ASD) are neurodevelopmental disorders characterised by deficits in social communication or interaction and repetitive behaviours. Maternal immune activation (MIA) during the mid-pregnancy is a known risk factor for ASD. Although reported in 15% of affected individuals, little is known about the specificity of their clinical profiles. Adaptive skills represent a holistic approach to a person's competencies and reflect specifically in autism, their strengths and difficulties. Methods In this study, we hypothesised that individual with ASD with a history of MIA (MIA+) could be more severely socio-adaptively impaired than those without MIA during pregnancy (MIA−). To answer this question, we considered two independent cohorts of individuals with ASD (PARIS study and FACE ASD) screened for pregnancy history, and used a supervised and unsupervised statistical approach. Results We included 295 mother-child dyads with 14% of them with MIA+. We found that ASD-MIA+ individuals displayed more severe maladaptive behaviors, specifically in their socialization abilities. MIA+ directly influenced individual's socio-adaptive skills, independent of other covariates, including ASD severity. Interestingly, MIA+ may affected persistently the socio-adaptive behavioral trajectories of individuals with ASD. Limitations : The current study has a retrospective design with possible recall bias regarding the MIA event and, even if pooled from two cohorts, has a relatively small population. In addition, we were limited by the number of covariables available potentially impacted socio-adaptive behaviors. Larger prospective study with additional dimensions related to ASD is needed to confirm our results Conclusions Specific pathophysiological pathways may explain these clinical peculiarities of ASD- MIA+ individuals, and may open the way to new perspectives in deciphering the phenotypic complexity of autism and for the development of specific immunomodulatory strategies.

Introduction: Tramadol* is a synthetic opioid agonist used as an analgesic. Despite its minor potential of addiction, it created recently a lot of concern. Its misuse may be motivated by a need to control the pain or by looking for her euphoric character. The aim of our study was to proceed a psychopathological reading of a case of addiction to Tramadol in a sickle cell patient with histrionic personality traits. Methods: We report the case’s management of a patient with addiction to Tramadol in a sickle cell patient with histrionic personality traits. The diagnosis was based on the DSM IV criteria. The review was done in the model of semi-structured interviews. Observation: Miss DP is 23 years old, sickle cell patient (AS profile). It is addressed to us for the management of an excessive consumption of Tramadol* started 4 years ago. Because of the difficulties of care in outpatient, we conducted hospitalization. The interviews highlight the histrionic personality traits and disruption of family dynamics. Discussion: Painful chronic diseases require a long analgesic treatment. It is a factor of dependence specially when the patient has a personality disorder. Multidisciplinary treatment between psychiatrist and addiction specialist and medical doctor is a guarantee of success.

Autism spectrum disorder (ASD) is a very heterogeneous disorder. Obsessive compulsive disorder (OCD) comorbidity, frequent in ASD, could be useful to define a specific ASD subtype. Our objective was to explore if adults with ASD and comorbid OCD could present a specific clinical profile of ASD in 89 high functioning-adult ASD patients. We found that adults with ASD and comorbid OCD showed a lower verbal IQ and a more severe impairments in social cognition. ASD with comorbid OCD present a specific clinical profile which could constitute a possible subtype of ASD.
