Although ADHD comorbidity has been widely studied, some issues remain unsolved. This multicenter observational study aims to examine comorbid psychiatric disorders in a clinical sample of newly diagnosed, treatment naïve children and adolescents with and without ADHD and, to compare treatment efficacy based on the type of comorbidity. We performed an analysis of the medical records of patients identified from the Regional ADHD Registry database, enrolled in 18 ADHD centers in the 2011-2016 period. 1919 of 2861 subjects evaluated (67%) met the diagnostic criteria for ADHD: 650 (34%) had only ADHD, while 1269 (66%) had at least one comorbid psychiatric disorder (learning disorders, 56%; sleep disorders, 23%; oppositional defiant disorder, 20%; anxiety disorders, 12%). Patients with ADHD of combined type and with severe impairment (CGI-S ≥5) were more likely to present comorbidity. 382 of 724 (53%) followed up patients improved after 1 year of treatment. ADHD with comorbidity showed greater improvement when treated with combined interventions or methylphenidate alone. Specifically, combined treatment showed significant superiority for ADHD with learning disorders (ES 0.66) and ODD (ES 0.98), lower for ADHD with sleep or anxiety disorders. Training intervention alone showed only medium efficacy (ES 0.50) for ADHD and learning disorders. This study was the first describing comorbidity patterns of ADHD in Italy, confirming, in a multicenter clinical setting, that ADHD is more often a complex disorder. Findings highlight important diagnostic, therapeutic, and service organization aspects that should be broadly extended to ensure an appropriate and homogenous ADHD management.

Several psychiatric conditions, both internalizing and externalizing, have been documented in comorbidity with Asperger Syndrome (AS) and High Functioning Autism (HFA). In this review we examine the interplay between psychiatric comorbidities and AS/HFA. In particular, we will focus our attention on three main issues. First, we examine which psychiatric disorders are more frequently associated with AS/HFA. Second, we review which diagnostic tools are currently available for clinicians to investigate and diagnose the associated psychiatric disorders in individuals with AS/HFA. Third, we discuss the challenges that clinicians and researchers face in trying to determine whether the psychiatric symptoms are phenotypic manifestations of AS/HFA or rather they are the expression of a distinct, though comorbid, disorder. We will also consider the role played by the environment in the manifestation and interpretation of these symptoms. Finally, we will propose some strategies to try to address these issues, and we will discuss therapeutic implications.

BackgroundChildren with chronic illnesses are known to have increased risks for emotional and behavioral problems. In the present study, children and adolescent suffering from celiac disease (CD) were compared with healthy controls to assess differences in the psychological profile.MethodsA total of 100 well-treated and compliant CD patients (65 females/35 males; age mean ± SD: 10.38 ± 2.71) were compared to 100 normal controls (58 females/42 males; age mean ± SD: 11.47 ± 2.61). Emotional and behavioral problems were assessed by the Child Behavior Checklist (CBCL), the Children's Depression Inventory (CDI) and the Multidimensional Anxiety Scale for Children (MASC).ResultsSubjects with CD self-reported an increased rate of anxiety and depression symptoms and showed higher scores in "harm avoidance" and "somatic complaints", in the CBCL parent-report questionnaire, as compared to healthy control subjects. Furthermore, gender differences could be observed in the group of CD patients, with males displaying significantly higher CBCL externalizing scores, in social, thought and attention problems, as compared to female, who in turns showed more prominent internalizing symptoms such as depression.ConclusionsThe increased rate of emotional and behavioral problems in children and adolescent with CD emphasizes the importance of an early detection of mental health problems in these children.

Care continuity in mental healthcare remains a need to be prioritized and better defined also for ADHD patients (and their parents). Parents' and clinicians' experiences are more likely to be positive if transition management is characterized by a gradual preparation, a period of parallel care, and commonly acknowledged, clear information on available services and how to access them. Identifying the needs and barriers of the people representing the different roles (clinicians, parents, and users) involved in the transition to adult mental health services is of particular importance in designing effective, shared transfer planning procedures.

Asperger Syndrome (AS) and High Functioning Autism (HFA) are psychiatric conditions belonging to the Autistic Spectrum Disorders (ASDs), characterized by social dysfunction and focused interest, in the absence of mental retardation. Previous reports suggest that AS/HFA may be associated with important psychiatric comorbidities. Among the psychiatric internalizing disorders, depression and anxiety are probably the most common disorders. The aim of this study is to evaluate the prevalence of mood disorders and identifying peculiar clinical features in subjects suffering from AS and HFA. 30 male patients with AS/HFA, 30 male patients affected by Major Depression (MD) and 35 male Typically Developing (TD) comparison were assessed with the CDI and the CDRS-R. Participants' parents were invited to complete the CBCL and the P-YMRS. Moreover, the CGAS was rated by the clinicians. The evaluation of depressive symptoms showed that AS/HFA group reported higher depressive symptoms, as showed by CDI total, CBCL internalizing and CDRS-R total, compared to the TD group. No significant difference of depressive symptoms was found between the AS/HFA and the MD group, with the exception of CDRS-R total score. Moreover, linear regression analysis in the AS/HFA group between CGAS and depressive symptoms revealed that a higher level of depressive symptoms increased the risk of poorer global functioning. These results suggest that the depressive symptoms in AS/HFA patients may be associated with poorer global functioning, with a consequent impairment in their psychological profile and social adjustment, and should alert clinicians to the importance of assessing mood disorders in order to choose the appropriate treatment.

The innate response to a pathogen is critical in determining the outcome of the infection. However, the interplay of different cellular responses that are activated following viral infection and their contribution to innate antiviral signalling has not been clearly established. This work shows that flaviviruses, including Dengue, Zika, West Nile and Tick-borne encephalitis viruses, activate the unfolded protein response before transcription of interferon regulatory factor 3 induced genes. Infection in conditions of unfolded protein response priming leads to early activation of innate antiviral responses and cell intrinsic inhibition of viral replication, which is interferon regulatory factor 3 dependent. These results demonstrate that the unfolded protein response is not only a physiological reaction of the cell to viral infection, but also synergizes with pattern recognition sensing to mount a potent antiviral response.

BackgroundAttention deficit hyperactivity disorder (ADHD) is recognized as the most common, and most studied, developmental age disorder. Basic information, such as the most appropriate case definition and the best way to evaluate the disorder’s prevalence rate, however, remains an open issue.MethodsA comprehensive meta-analysis on the epidemiology of ADHD in Italy, which was lacking from the literature, was therefore performed to attempt to estimate the actual prevalence rate of ADHD, highlighting conceptual and quantitative differences between clinical-diagnosis and survey-based symptoms studies. The Medline, Embase, and PsycINFO databases, and the grey literature, were searched up to January 2018. The review was laid out in three main sections: an overall prevalence estimate, an epidemiological profile of ADHD symptoms, and an attempt to define the actual rate of ADHD diagnosis, as emerged from Italian studies.ResultsA total of 15 unique studies were included. These contributed to estimating the prevalence of ADHD in 67,838 subjects aged 5–17, representing 9 of the 20 regions (45%) of Italy. Overall, the pooled prevalence of ADHD was 2.9% (range: 1.1–16.7%). When distinguishing studies based on case definition, however, we found an average prevalence estimate, based on symptoms criteria, of 5.9% (range: 1.4 to 16.7%) and a best-estimate prevalence rate of 1.4% (range: 1.1 to 3.1%).ConclusionsFollowing the case definition for epidemiological studies of ADHD, counting only subjects with an ADHD diagnosis performed and confirmed by clinical assessment would reduce the wide variability in prevalence estimates, and, above all, would both describe the real rate of subjects suffering from ADHD disorder and avoid misdiagnosis.
