Sex Differences in the Relationship between PTSD Spectrum Symptoms and Autistic Traits in a Sample of University Students

Rumination and altered reactivity to sensory input as vulnerability factors for developing post-traumatic stress symptoms among adults with autistic traits

OBJECTIVE

Recent literature has suggested that individuals with autism spectrum disorder (ASD) or autistic traits (ATs) would be more likely to encounter traumatic events in their lifetime and to develop post-traumatic stress disorder (PTSD). However, the nature of this relationship has not yet been fully elucidated. The aims of this study were to evaluate the relationship between AT and PTSD and to investigate which specific autistic dimension was more associated with trauma and stress-related symptoms.

METHODS

A total of 68 subjects with ASD and 64 healthy controls (HCs) were assessed with the Adult Autism Subthreshold Spectrum (AdAS Spectrum) and the Trauma and Loss Spectrum (TALS) questionnaires. Statistical analyses included Mann-Whitney U test, chi-square test, calculation of Spearman's coefficients, and logistic regression analysis.

RESULTS

Patients with significant AT reported a 30% rate of PTSD and higher TALS total and domain scores than HCs, among whom no PTSD was found instead. Significant positive correlations were reported between AdAS Spectrum and TALS-SR scores in the whole sample. AdAS Spectrum total scores were statistically predictive of the presence of PTSD. High scores at AdAS Spectrum Inflexibility and adherence to routine and Restrictive interest and rumination domains were identified as positive predictors of a probable PTSD.

CONCLUSION

Compared to HCs, subjects with significant AT are more likely to present symptoms of PTSD. In particular, AT related to ruminative thinking, narrow interests, and sensorial reactivity would seem to predict the presence of post-traumatic stress symptomatology.

Emotional dysregulation as a part of the autism spectrum continuum: a literature review from late childhood to adulthood

The concept of emotional dysregulation (ED) has recently gained interest in the scientific literature and is commonly defined as the inability to use the modulatory mechanisms involved in emotion regulation, resulting in a functioning meaningfully below the baseline. Even though the data available are still limited, an increasing number of studies have hypothesized a promoting role for some of the core features of autism spectrum disorder (ASD) in the development of ED, in particular being repetitive behaviors, social difficulties and alexythimia. In this framework, the purpose of this study was to review the literature that is currently available about presence and correlates of ED in young adults with autism spectrum conditions as well as to offer some insights about possible implications for illness trajectories. The data reported seems to point to a shared etiology between ED and repetitive/restricted ASD symptoms, with perseveration features serving as the foundation for the inability to control one's emotions. In this context, a neurodevelopmental basis for ED could be consistent with the transnosographic conceptualization of ASD, which hypothesizes a potential neurodevelopmental basis for several psychiatric disorders, whose autistic traits would be the phenotypical presentation.

Autism Spectrum, Hikikomori Syndrome and Internet Gaming Disorder: Is There a Link?

The aim of this study is to review the available literature investigating the relationship between hikikomori, a pathological condition characterized by severe social withdrawal or isolation, autism spectrum disorder (ASD) and Internet gaming disorder (IGD). Studies on the relationship between ASD and IGD have found significant positive correlations between these two conditions. Individuals with ASD would appear to be at risk of developing a problematic use of the Internet, which, to the right extent, would represent a useful tool for social interaction and cognitive development. Even subjects with hikikomori, in whom rarefied interpersonal relationships and social isolation could be balanced by the use of online connections, appear to be at high risk of developing IGD. On the other hand, the finding of significant autistic traits in populations with hikikomori could lead to considering this psychopathological condition as a particular presentation of autism spectrum, a hypothesis that requires further investigation.

Unlocking the Secrets: Exploring the Biochemical Correlates of Suicidal Thoughts and Behaviors in Adults with Autism Spectrum Conditions

Involving 1 million people a year, suicide represents one of the major topics of psychiatric research. Despite the focus in recent years on neurobiological underpinnings, understanding and predicting suicide remains a challenge. Many sociodemographical risk factors and prognostic markers have been proposed but they have poor predictive accuracy. Biomarkers can provide essential information acting as predictive indicators, providing proof of treatment response and proposing potential targets while offering more assurance than psychological measures. In this framework, the aim of this study is to open the way in this field and evaluate the correlation between blood levels of serotonin, brain derived neurotrophic factor, tryptophan and its metabolites, IL-6 and homocysteine levels and suicidality. Blood samples were taken from 24 adults with autism, their first-degree relatives, and 24 controls. Biochemical parameters were measured with enzyme-linked immunosorbent assays. Suicidality was measured through selected items of the MOODS-SR. Here we confirm the link between suicidality and autism and provide more evidence regarding the association of suicidality with increased homocysteine (0.278) and IL-6 (0.487) levels and decreased tryptophan (-0.132) and kynurenic acid (-0.253) ones. Our results suggest a possible transnosographic association between these biochemical parameters and increased suicide risk.

Autistic traits distribution in different psychiatric conditions: A cluster analysis on the basis of the Adult Autism Subthreshold Spectrum (AdAS Spectrum) questionnaire

Increasing interest is being paid on full-threshold and sub-threshold autism spectrum conditions among adults. Sub-threshold autistic traits (AT) seem to be distributed in a continuum from the clinical to the general population, being particularly higher among subjects with other psychiatric disorders. The aim of the present study was to evaluate the distribution of AT in a sample of subjects with different psychiatric conditions by means of a cluster analysis on the basis of the score reported to the AdAS Spectrum instrument. A total of 738 subjects recruited by seven Italian Universities were divided in 5 groups depending on the clinical diagnosis: Autism spectrum disorder (ASD), subthreshold ASD symptoms (partial ASD), Bipolar disorder (BD), Feeding and eating disorders (FED), and controls (CTLs). All subjects were assessed with the AdAS Spectrum. The cluster analysis identified 3 clusters: the high, medium and low autism clusters. The Restricted interests and rumination domain reported the highest influence in forming the clusters. The high, medium and low autism clusters were respectively more represented in the ASD, partial ASD and CTL groups. The clusters were represented intermediately in the FED and BD groups, confirming the presence of intermediate levels of AT in these clinical populations.

A comprehensive perspective of autistic traits and catatonic symptoms in a patient with Fronto-Temporal Dementia and Bipolar Disorder: a case report

BACKGROUND

Fronto-Temporal Dementia (FTD) is a neurodegenerative disorder featuring frontotemporal lobe atrophy which leads to profound changes in behavior and cognition in the affected subjects. Considering that the onset of this type of dementia is typically characterized by the development of affective symptoms, differential diagnosis between FTD and Bipolar Disorder (BD) is particularly difficult. An important overlapping feature between BD and FTD is the presence of catatonic symptoms: Catatonia is extremely frequent in FTD, and, on the other hand, BD is the psychiatric disease with the highest frequency of association with catatonic states. In this framework, it should be noted that also Autism Spectrum conditions have been reported to show high rates of comorbidity and overlapping features with BD. In addition, subjects with autistic traits were reported to show an increased vulnerability towards the development of mood and anxiety disorders, as well as increase the risk of mood episodes with mixed features, suicidal thoughts and catatonic symptoms.

CASE PRESENTATION

We reported the case of a patient with a diagnosis of both BD and FTD who showed catatonic symptoms.

OBJECTIVES

The aim of this case report is to evaluate the possible role of autistic traits in the illness trajectory of BD and FTD.

CONCLUSION

This case confirms the presence of a continuum between psychiatric and neurological conditions, which should be considered as expressions of a same neurobiological system and further investigated in light of an integrative model.

Measuring Social Camouflaging in Individuals with High Functioning Autism: A Literature Review

In the recent years, growing attention has been paid to the use of camouflaging strategies by adult populations suffering from autism spectrum disorder (ASD) with milder manifestations and without intellectual impairment, which may lead to a delay in diagnosis or even a misdiagnosis. In fact, high-functioning ASD individuals were reported to be more aware of their communication difficulties and were more likely make considerable efforts to adjust their behavior to conventional rules of non-autistic individuals, learning to imitate other non-ASD individuals. Moreover, females reported a higher frequency of camouflaging strategies, suggesting a role of camouflaging in the gender gap of the ASD diagnosis. Although camouflaging strategies can sometimes grant a better level of adjustment, even resulting in a hyper-adaptive behavior, they are also often correlated with negative mental health consequences due to the long-term stress associated with continuous attempts to adapt in day-to-day life. In this framework, the aim of the present work was to review the available studies that assessed the presence and correlates of camouflaging strategies in individuals with ASD. Although the literature available on the topic is still scarce, some interesting correlations between camouflaging and anxious and depressive symptoms, as well as suicidality, were highlighted. In particular, the controversial and sometime opposite thoughts and results about camouflaging may be clarified and integrated in light of a dimensional approach to psychopathology.

Autistic traits and camouflaging behaviors: a cross-sectional investigation in a University student population

BACKGROUND

Increasing research is stressing the importance of identifying autistic traits (ATs) in clinical and general populations. University students may be a group at higher risk for the presence of ATs. Recently, specific attention has been paid to camouflaging strategies used by subjects in the autism spectrum in order to cope with the social environment. The aim of this work was to evaluate the prevalence of ATs and camouflaging behaviors in a population of University students.

METHODS

Subjects were requested to anonymously fill out through an online form the Adult Autism Subthreshold Spectrum and the Camouflaging AT Questionnaire.

RESULTS

ATs were more represented among males and among students of specific fields of study. Camouflaging behaviors were significantly more frequent among subjects with more severe autism spectrum symptoms, without differences depending from sex.

CONCLUSIONS

Our study confirms the strong association between ATs and camouflaging behaviors and the relationship between ATs, sex, and specific fields of study.

Orthorexia and autism spectrum in University workers: relationship with gender, body mass index and dietary habits

OBJECTIVE

To date, few studies have investigated the relationship between autistic traits and emerging phenotypes of restrictive disorders, such as Orthorexia nervosa (ON). The aim of the present work was to investigate the relationship between ON symptoms and autistic traits in a population of University employees, focusing on the impact of gender, weight and type of diet.

METHODS

All academic and technical/administrative workers of University of Pisa were invited by mail to fulfil through an anonymous online form the Adult Autism Sub-threshold Spectrum (AdAS Spectrum) and the ORTO-R.

RESULTS

A total of 285 subjects filled out the questionnaires. Participants with significant autistic traits were included into the Broad autism phenotype (BAP) group, while others into the No BAP group. Subjects in the BAP group reported significantly higher ORTO-R scores than others, while no difference was reported for gender, work position, type of diet, age and BMI. Females showed significantly higher ORTO-R scores and lower BMI than males. Older subjects showed a higher BMI. No significant differences in ORTO-R scores were reported depending on type of diet and work position. A decision tree model, with ORTO-R score as dependent variable, revealed in the first step significantly higher ORTO-R scores in the BAP group than in the No BAP group, and in the second step significantly higher ORTO-R scores among females only in the No BAP group.

CONCLUSION

Our results further confirm the association between ON and autism spectrum, which seems to overcome the impact of gender in this population.

LEVEL OF EVIDENCE

Level V, descriptive study.

An attempted "suicide pact" in Covid-19 era - psychiatric perspectives

BACKGROUND

A "suicide pact" is a joint and actively induced death of two individuals with the essential and unavoidable characteristic of a mutual consent. One of the partners (dominant in the relationship, commonly male) usually induces the action and in most cases, it is the one who actively carries it out. Undiagnosed psychopathological dimension or pathological subthreshold traits are found in those who enter into suicide agreements, the presence of cluster B personality traits such as narcissistic or borderline is of particular relevance in the dominant partner, while in the submissive one dependent personality traits are more frequent. As in the case of other similar health emergencies, COVID-19 pandemic seems to lead to greater suicidality, including the "suicide pacts" of couples whose motivation varies including firstly financial problems, strictly followed by fear of infection and not being able to return home from abroad.

CASE PRESENTATION

We reported a case of a couple who entered a suicide agreement consequently to the economic difficulties caused by COVID-19 pandemic, hospitalized in our department. Both partners were assessed with Adult Autism Subthreshold Spectrum (AdAS Spectrum) and both crossed the threshold for clinically relevant autistic traits (M = 67; F = 49).

CONCLUSION

This case further confirms the link between COVID-19 pandemics and suicidality. The role of autism spectrum traits as a vulnerability factor towards the development of severe psychopathological consequences after traumatic events is also stressed.

Eating disorders and autism spectrum: links and risks

In the last decades, increasing attention has been provided to socio-cultural and neurobiological factors involved in the psychopathology of feeding and eating disorders (FED), encouraging a multifactorial approach. In this framework, several authors stressed an association between FED and other kinds of psychiatric disorders from both a psychopathological and a neurobiological point of view. In particular, many promising contributions are focusing on the possible link between FED and autism spectrum disorder (ASD). Growing interest about this association rose from the frequently reported evidence of ASD-like traits amongst FED patients and abnormal eating behaviors amongst patients with ASD. This narrative review overview aims to summarize the most relevant findings about the overlap between different kinds of FED and the autism spectrum, taking into account the most recent hypotheses about the psychopathology of both these conditions. While most of the studies focused on anorexia nervosa, both ASD and autistic traits seem to be detectable also in other kinds of FED. In addition, the recently increased interest toward a dimensional approach to psychopathology led to progressively broadening the concept of ASD, focusing on its subthreshold and gender-specific manifestations and on its link with other psychiatric conditions, including FED. Globally the studies summarized here provide further support to theoretical models featuring a neurodevelopmental approach for mental disorders. In particular, FED have been conceptualized as a possible psychopathological trajectory of a neurodevelopmental alteration, toward which female gender would act as one of many predisposing factors.

Kynurenine pathway and autism spectrum phenotypes: an investigation among adults with autism spectrum disorder and their first-degree relatives

BACKGROUND

Increasing literature highlighted alterations of tryptophan (TRP) metabolism and kynurenine (KYN) pathway in children with autism spectrum disorder (ASD). However, no study specifically focused on adult samples. Meanwhile, several authors stressed the relevance of investigating neurobiological correlates of adult forms of ASD and of those subthreshold ASD manifestations frequently found in relatives of ASD probands, known as broad autism phenotype (BAP). This work aimed to evaluate circulating levels of TRP and metabolites of KYN pathway in a sample of ASD adults, their first-degree relatives and controls (CTLs), investigating also the correlations between biochemical variables' levels and ASD symptoms.

METHODS

A sample of ASD adults, together with a group of first-degree relatives (BAP group) and unrelated CTLs were assessed by means of psychometric scales. Circulating levels of TRP, KYN, quinolinic acid (QA), and kynurenic acid (KYNA) were assessed in all subjects.

RESULTS

ASD patients reported significantly higher total scores than the other groups on all psychometric scales. BAP subjects scored significantly higher than CTLs. ASD patients reported significantly lower TRP levels than BAP and CTL groups. Moreover, significantly lower levels of KYNA were reported in both ASD and BAP groups than in CTLs. Specific patterns of associations were found between autism symptoms and biochemical variables.

CONCLUSIONS

Our findings confirm in adult samples the presence of altered TRP metabolism through KYN pathway. The intermediate alterations reported among relatives of ASD patients further stress the presence of a continuum between subthreshold and full-threshold ASD phenotypes also from a biochemical perspective.

Biological correlates of altered circadian rhythms, autonomic functions and sleep problems in autism spectrum disorder

Autism spectrum disorder (ASD) is a neurodevelopmental condition characterized by a complex and multifaceted neurobehavioral syndrome. In the last decades, several studies highlighted an increased prevalence of sleep problems in ASD, which would be associated with autonomic system and circadian rhythm disruption. The present review aimed to summarize the available literature about sleep problems in ASD subjects and about the possible biological factors implicated in circadian rhythm and autonomic system deregulation in this population, as well as possible therapeutic approaches. Shared biological underpinnings between ASD symptoms and altered circadian rhythms/autonomic functions are also discussed. Studies on sleep showed how ASD subjects typically report more problems regarding insufficient sleep time, bedtime resistance and reduced sleep pressure. A link between sleep difficulties and irritability, deficits in social skills and behavioral problems was also highlighted. Among the mechanisms implicated, alteration in genes related to circadian rhythms, such as CLOCK genes, and in melatonin levels were reported. ASD subjects also showed altered hypothalamic pituitary adrenal (HPA) axis and autonomic functions, generally with a tendency towards hyperarousal and hyper sympathetic state. Intriguingly, some of these biological alterations in ASD individuals were not associated only with sleep problems but also with more autism-specific clusters of symptoms, such as communication impairment or repetitive behaviors Although among the available treatments melatonin showed promising results, pharmacological studies for sleep problems in ASD need to follow more standardized protocols to reach more repeatable and reliable results. Further research should investigate the issue of sleep problems in ASD in a broader perspective, taking into account shared pathophysiological mechanisms for core and associated symptoms of ASD.

PTSD and Depression in Healthcare Workers in the Italian Epicenter of the COVID-19 Outbreak

Background:

Increasing evidence highlights the susceptibility of Healthcare Workers to develop psychopathological sequelae, including Post-Traumatic Stress Disorder (PTSD) and depression, in the current COronaVIrus Disease-19 (COVID-19) pandemic, but little data have been reported in the acute phase of the pandemic.

Objective:

To explore Healthcare Workers’ mental health reactions in the acute phase of the COVID-19 pandemic in the first European epicenter (Lodi/Codogno, Italy), with particular attention to post-traumatic stress and depressive symptoms and their interplay with other psychological outcomes.

Methods:

74 Healthcare Workers employed at the Azienda Socio Sanitaria Territoriale of Lodi (Lombardy, Italy) were recruited and assessed by means of the Impact of Event Scale- Revised, the Professional Quality of Life Scale-5, the Patient Health Questionnaire-9, the Generalized Anxiety Disorder-7 item, the Resilience Scale and the Work and Social Adjustment Scale. Socio-demographic and clinical variables were compared across three subgroups of the sample (No PTSD, PTSD only, PTSD and depression).

Results:

A total of 31% of subjects endorsed a diagnosis of PTSD and 28.4% reported PTSD comorbid with major depression. Females were more prone to develop post-traumatic stress and depressive symptoms. Subjects with PTSD and depression groups showed high levels of PTSD, depression, burnout and impairment in functioning. Anxiety symptoms were higher in both PTSD and depression and PTSD groups rather than in the No PTSD group.

Conclusion:

Our results showed high rates of PTSD and depression among Healthcare Workers and their comorbidity overall being associated with worse outcomes. Current findings suggest that interventions to prevent and treat psychological implications among Healthcare Workers facing infectious outbreaks are needed.

Validation of the Italian version of the Camouflaging Autistic Traits Questionnaire (CAT-Q) in a University population

The Camouflaging Autistic Traits Questionnaire (CAT-Q) is an instrument recently developed and validated in English for measuring social camouflaging. While increasing research is focusing on camouflaging behaviours often used for masking autistic traits in social contexts, the CAT-Q remains the only self-report instrument in this field. We aimed to validate the Italian version of the CAT-Q, further testing its validity and reliability in a large Italian University population (N = 2439). We employed the Adult Autism Subthreshold Spectrum (AdAS Spectrum) for assessing autism spectrum conditions. The CAT-Q demonstrated excellent internal consistency and test-retest reliability, as well as strong correlations with the AdAS Spectrum. Our results confirm that the CAT-Q is a valuable instrument for evaluating social camouflaging.

Investigating Orthorexia Nervosa With the ORTO-R in a Sample of University Students With or Without Subthreshold Autism Spectrum: Focus on Dietary Habits and Gender Differences

BACKGROUND

The aim of the present study was to investigate the presence of Orthorexia (ON) symptoms in a sample of University students with or without autistic traits (AT), specifically focusing on evaluating the role of gender and of dietary habits in the association between ON and autism spectrum.

METHODS

Subjects were requested to anonymously fill out the questionnaires through an online form.

RESULTS

Two thousand one hundred forty students participated in the study. Subjects with significant AT, measured by means of the Adult Autism Sub-threshold spectrum (AdAS Spectrum) reported significantly higher ON symptoms, as measured by ORTO-R scores, than subjects with low AT. Females and subjects following a vegetarian/vegan diet reported significantly higher ORTO-R scores than males and than subjects following an omnivorous diet, respectively. Significant positive correlations were found between ORTO-R and AdAS Spectrum scores. A decision tree model, with gender, type of diet and presence of high AT as independent variables and ORTO-R score as dependent variable, showed in the first step the presence of significantly higher ORTO-R scores among females than among males, and in the second step showed in both genders the presence of higher ORTO-R scores among subjects with high AT than in those with low AT. A significant interaction of gender and presence/absence of high AT was reported on ORTO-R score, with a higher increasing trend of ORTO-R score with the increase of AdAS Spectrum score among females than among males.

CONCLUSIONS

Our results further highlighted the association between AT and ON, in particular among females.

Gender and occupational role differences in work-related post-traumatic stress symptoms, burnout and global functioning in emergency healthcare workers

OBJECTIVES

To explore gender and occupational role impact on work-related Post-Traumatic Stress Symptoms, Post-Traumatic Stress Disorder, burnout and global functioning in a sample of emergency healthcare workers.

DESIGN

A cross-sectional study.

PARTICIPANTS/SETTING

126 healthcare workers of the Emergency Department, including Intensive Care Unit, Emergency Room and Emergency Medicine, of a major University Hospital in central Italy were recruited.

MAIN OUTCOME MEASURES

Participants were assessed by means of the: Trauma and Loss Spectrum-Self Report (TALS-SR) to explore Post-Traumatic Stress Spectrum Symptoms, Professional Quality of Life (ProQOL) Scale to assess Compassion Satisfaction, Burnout and Compassion Fatigue and Work and Social Adjustment Scale (WSAS) to measure global functioning.

RESULTS

The present findings showed females were more prone to develop Post-Traumatic Stress Symptoms, particularly re-experiencing (p = .010) and hyperarousal (p = .026) symptoms and medical doctors reporting higher Burnout (p < .001) and lower Compassion Satisfaction (p = .009) mean scores than nurses. Higher levels of functioning impairment emerged amongst medical doctors rather than nurses, in both social (p = .029) and private (p = .020) leisure activities. Linear correlations highlighted relationships between the TALS-SR, ProQOL and WSAS scores. Finally, medical doctor status was significantly associated with lower Compassion Satisfaction (p = .029) and higher Burnout (p = .015).

CONCLUSION

Our results highlight high post-traumatic stress symptoms and burnout levels in emergency healthcare workers with a relevant impact of female gender and occupational role, supporting the need for preventive strategies, also in light of the current COVID-19 pandemic.

After the Pandemic: The Future of Italian Medicine. The Psychological Impact of COVID-19 on Medical and Other Healthcare-Related Degrees Students

Objective: The study aimed to explore the psychological symptoms and the readiness to fight the pandemic of the new generation of healthcare professionals: medical and other healthcare degree students. Methods: We enrolled 509 medical and healthcare-related degree students during the second outbreak of COVID-19 in Italy. We have examined their psychological symptoms using the 12-item General Health Questionnaire (GHQ-12) and their readiness to fight the pandemic together with their academic career status, their relationship with the university, and their emotional reactions to the pandemic with Visual Analog Scales. Results: We retrieved a GHQ mean of 21.65 (SD = 40.63) and readiness to fight the pandemic mean of 53.58 (SD = 31.49). Perceived control affects variables: a negative effect on psychological symptoms and a positive effect on the willingness to fight the pandemic. The other variables with an impact were stress, loneliness, and anger that had a significant and positive impact on psychological symptoms. Age and concern for patients had a significant positive impact on readiness to fight for the pandemic, while years of attendance had a significant but negative impact. Conclusion: Universities and Institutions should consider the impact of the pandemic on students, in particular, for its effect on their mental health.

Autism spectrum in patients with schizophrenia: correlations with real-life functioning, resilience, and coping styles

BACKGROUND

Previous researches highlighted among patients with schizophrenia spectrum disorders (SSD) a significant presence of autistic traits, which seem to influence clinical and functional outcomes. The aim of this study was to further deepen the investigation, evaluating how patients with SSD with or without autistic traits may differ with respect to levels of functioning, self-esteem, resilience, and coping profiles.

METHODS

As part of the add-on autism spectrum study of the Italian Network for Research on Psychoses, 164 outpatients with schizophrenia (SCZ) were recruited at eight Italian University psychiatric clinics. Subjects were grouped depending on the presence of significant autistic traits according to the Adult Autism Subthreshold Spectrum (AdAS Spectrum) instrument ("AT group" vs "No AT group"). Other instruments employed were: Autism Spectrum Quotient (AQ), Specific Levels of Functioning (SLOF), Self-Esteem Rating scale (SERS), Resilience Scale for Adults (RSA), and brief-COPE.

RESULTS

The "AT group" reported significantly higher scores than the "No AT group" on SLOF activities of community living but significantly lower scores on work skills subscale. The same group scored significantly lower also on SERS total score and RSA perception of the self subscale. Higher scores were reported on COPE self-blame, use of emotional support and humor domains in the AT group. Several correlations were found between specific dimensions of the instruments.

CONCLUSION

Our findings suggest the presence of specific patterns of functioning, resilience, and coping abilities among SSD patients with autistic traits.

Suicidality and Illness Course Worsening in a Male Patient with Bipolar Disorder during Tamoxifen Treatment for ER+/HER2+ Breast Cancer

PURPOSE

Tamoxifen is a selective estrogenic receptor modulator (SERM) drug. In addition to its common use in breast cancer ER+, Tamoxifen has been object of growing interest in psychiatry as antimanic drug. At the same time, clinical concerns about Tamoxifen's depressogenic effect have been repeatedly raised even without reaching univocal conclusions. We discuss the case of a 45-year-old-male with a diagnosis of Bipolar Disorder type II, treated with Tamoxifen as relapse prevention treatment after surgery for a ER+/HER2+ breast cancer. The patient required two psychiatric admissions in a few-month time span since he showed a progressive worsening of both depressive and anxiety symptoms, with the onset of delusional ideas of hopelessness and failure up to suicidal thoughts. The clinical picture showed poor response to treatment trials based on various associations of mood-stabilising, antidepressants, and antipsychotic drugs. During the second hospitalization, after a multidisciplinary evaluation, the oncologists agreed on Tamoxifen discontinuation upon the severity of the psychiatric condition. The patient underwent a close oncological and psychiatric follow-up during the following 12 months.

METHODS

Psychiatric assessments included the Montgomery-Asberg Depression Rating Scale (MADRS), the Hamilton Depression Scale (HAM-D), the Columbia Suicide Severity Rating Scale (C-SSRS), and the Quality of Life Enjoyment and Satisfaction Questionnaire Short Form (Q-LES-Q-SF). All questionnaires were administered at the time of the second hospitalization and in a one-year follow-up.

RESULTS

Suicidal ideation fully remitted and depressive symptoms markedly and rapidly improved in the aftermath of Tamoxifen discontinuation. The symptomatological improvement remained stable across one-year follow-up.

CONCLUSIONS

Male patients with a mood disorder history constitute a high-risk group as to Tamoxifen psychiatric side effects. The onset or worsening of depressive symptoms or suicidality should be carefully addressed and promptly treated, and clinicians should be encouraged to consider the possibility of discontinue or reduce Tamoxifen therapy after a multidisciplinary evaluation.

Post-Traumatic Stress Reactions in Caregivers of Children and Adolescents/Young Adults with Severe Diseases: A Systematic Review of Risk and Protective Factors

Severe illnesses in children and adolescents/young adults (AYAs) may represent a complex burden for patients and their caregivers, including a wide range of mental disorders, particularly post-traumatic stress disorder (PTSD). Few events are as potentially traumatizing as having a son or a daughter diagnosed with a severe, life-threatening, or disabling disease. The presence of PTSD symptoms in caregivers may compromise their efficacy as caregivers and negatively affect the child’s well-being. This systematic review aims at outlining potential risk and protective factors for the development of PTSD symptoms in caregivers of children and AYAs affected by severe acute or chronic illnesses. Thirty-one studies on caregivers of children and AYAs affected by severe, acute, or chronic diseases were included. Socio-demographic and socio-economic characteristics, illness-related distress, psychiatric symptoms, support, and coping styles were found as potential risk/protective factors across studies. It is crucial to consider risk factors affecting caregivers of severely ill young patients, in order to plan focused interventions aimed at preventing an adverse clinical outcome in caregivers and at enhancing caregivers’ coping skills, in order to ultimately improve their quality of life.

Risk and Protective Factors for PTSD in Caregivers of Adult Patients with Severe Medical Illnesses: A Systematic Review

Caregivers of severely ill individuals often struggle to adjust to new responsibilities and roles while experiencing negative psychological outcomes that include depression, anxiety and Post-Traumatic Stress Disorder (PTSD). This systematic review aims to outline potential risk and protective factors for the development of PTSD in caregivers of adult subjects affected by severe somatic, potentially life-threatening illnesses. Twenty-nine studies on caregivers of adult patients affected by severe, acute, or chronic somatic diseases have been included. Eligibility criteria included: full-text publications reporting primary, empirical data; PTSD in caregivers of adult subjects affected by severe physical illnesses; risk and/or protective factors related to PTSD; and English language. Specific sociodemographic and socioeconomic characteristics, besides the illness-related distress, familiar relationships, exposure characteristics, coping style, and support, were identified as relevant risk/protective factors for PTSD. The review limitations are the small number of studies; studies on different types of diseases; studies with same samples. It is crucial to consider factors affecting caregivers of severely ill adult patients in order to plan effective intervention strategies aimed at reducing the risk of an adverse mental health outcome and at enhancing the psychological endurance of this population.

Subthreshold Autism Spectrum in a Patient with Anorexia Nervosa and Behçet's Syndrome

Recently, increasing research stressed the presence of subthreshold autistic traits in patients with other psychiatric conditions. In this framework, a significant relationship between anorexia nervosa (AN) and the autism spectrum has been frequently reported, in particular among female samples, to the point that AN has been hypothesized to be a female phenotype of autism spectrum disorder (ASD). On the other hand, among subjects with ASD has been reported a higher prevalence of immune diseases and altered immune functions. While these reports seem to support an association between neurodevelopmental and immune system alterations in ASD, the relationship between the immune system and the broader autism spectrum, including its subthreshold manifestations, remains poorly investigated. In this report, we described the presence of autistic traits in a male inpatient with AN and separation anxiety disorder, who also show a diagnosis of Behçet's syndrome (BS). This case seems to further stress the association between AN and the autism spectrum, which may not be limited to the female gender. Moreover, it further suggests a deeper link between neurodevelopmental and immune system alterations. Implications are discussed in light of the more recent neurobiological and psychopathological hypothesis about the autism spectrum.

Disrupted Rhythmicity and Vegetative Functions Relate to PTSD and Gender in Earthquake Survivors

Background: Increasing evidence indicates that survivors to traumatic events may show disruption of sleep pattern, eating and sexual behaviors, and somatic symptoms suggestive of alterations of biorhythmicity and vegetative functions. Therefore, the aim of this study was to investigate these possible alterations in a sample of survivors in the aftermath of earthquake exposure, with particular attention to gender differences and impact of post-traumatic stress disorder (PTSD). Methods: High school senior students, who had been exposed to the 2009 L'Aquila earthquake, were enrolled 21 months after the traumatic event and evaluated by the Trauma and Loss Spectrum Self-Report to investigate PTSD rates and by a domain of the Mood Spectrum Self-Report-Lifetime Version (MOODS-SR), to explore alterations in circadian/seasonal rhythms and vegetative functions. Results: The rates of endorsement of MOODS-SR rhythmicity and vegetative functions domain and subdomain scores were significantly higher in survivors with PTSD with respect to those without it. Among all earthquake survivors, women reported higher scores than men on the rhythmicity and vegetative functions domain and subdomain scores, except for the rhythmicity and sexual functions ones. Female survivors without PTSD showed significantly higher scores than men in the rhythmicity and vegetative functions total scores and the sleep and weight and appetite subdomains. Potentially traumatic events burden predicted rhythmicity and vegetative functions impairment, with a moderation effect of re-experiencing symptoms. Conclusions: We report impairments in rhythmicity, sleep, eating, and sexual and somatic health in survivors to a massive earthquake, particularly among subjects with PTSD and higher re-experiencing symptoms, with specific gender-related differences. Evaluating symptoms of impaired rhythmicity and vegetative functions seems essential for a more accurate assessment and clinical management of survivors to a mass trauma.

While these reports seem to support an association between neurodevelopmental and immune system alterations in ASD, the relationship between the immune system and the broader autism spectrum, including its subthreshold manifestations, remains poorly investigated. In this report, we described the presence of autistic traits in a male inpatient with AN and separation anxiety disorder, who also show a diagnosis of Behçet's syndrome (BS). This case seems to further stress the association between AN and the autism spectrum, which may not be limited to the female gender. Moreover, it further suggests a deeper link between neurodevelopmental and immune system alterations. Implications are discussed in light of the more recent neurobiological and psychopathological hypothesis about the autism spectrum.
