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

BACKGROUND

While growing literature is stressing the link between Autistic Traits (AT) and trauma-/stress-related disorders, in both conditions significant differences have been separately reported.

OBJECTIVE

This study aims to evaluate the relationship between AT and trauma-/stress-related symptoms with respect to sex.

METHODS

178 university students were assessed with the Structured Clinical Interview for DSM-5, the Trauma and Loss Spectrum (TALS) and the Adult Autism Subthreshold Spectrum (AdAS). In order to evaluate sex differences in trauma-/stress-related symptoms among subjects with higher or lower AT, the sample was split in two groups with an equal number of subjects on the basis of the median score reported on AdAS Spectrum ("AdAS high scorers" and "AdAS low scorers").

RESULTS

Females reported significantly higher TALS total score, Loss events and Grief reaction domain scores than males in the whole sample, while AdAS high scorers reported significantly higher TALS total and domain scores than AdAS low scorers. A significant interaction between high/low AdAS score and sex emerged for TALS domains, with females scoring significantly higher than males only among AdAS low scorers, specifically on Loss events, Grief reaction, Re-experiencing and Personal characteristics/Risk factors domains. Finally, among AdAS high scorers a significantly higher rate of subjects fulfilled symptomatological criteria for PTSD than among AdAS low scorers, without sex differences.

CONCLUSION

Our results confirm a significant relationship between AT and trauma-/stress-related symptoms, which seems to prevail on sex differences among high-risk subjects.

Systematic Review of Sleep Disturbances and Circadian Sleep Desynchronization in Autism Spectrum Disorder: Toward an Integrative Model of a Self-Reinforcing Loop

Background: A compelling number of studies, conducted in both children and adults, have reported an association between sleep disturbances/circadian sleep alterations and autism spectrum disorder (ASD); however, the data are sparse and the nature of this link is still unclear. The present review aimed to systematically collect the literature data relevant on sleep disturbances and circadian sleep dysrhythmicity related to ASD across all ages and to provide an integrative theoretical framework of their association. Methods: A systematic review of the MEDLINE, PubMed, and Cochrane databases was conducted from November 2018 to February 2019. The search strategies used were MeSH headings and keywords for "sleep-wake circadian rhythms" OR "circadian sleep disorders" OR "sleep-wake pattern" OR "sleep disorders" OR "melatonin" AND "autism spectrum disorder" OR "autism". Results: One hundred and three studies were identified, 15 regarded circadian sleep dysrhythmicity, 74 regarded sleep disturbances, and 17 regarded melatonin alterations in children and adults with ASD. Our findings suggested that autistic subjects frequently present sleep disturbances in particular short sleep duration, low sleep quality/efficiency, and circadian sleep desynchronization such as delayed phases and/or eveningness. Sleep disturbances and circadian sleep alterations have been related to the severity of autistic symptoms. Genetic studies have shown polymorphisms in circadian CLOCK genes and in genes involved in melatonin pathways in subjects with ASD. Conclusions: Sleep disturbances and circadian sleep alterations are frequent in subjects with autistic symptoms. These subjects have shown polymorphisms in clock genes expression and in genes involved in melatonin production. The impairment of circadian sleep regulation may increase the individual's vulnerability to develop symptoms of ASD by altering the sleep regulation in toto, which plays a key role in normal brain development. Even though controversies and "research gaps" are present in literature at this point, we may hypothesize a bidirectional relation between circadian sleep dysfunction and ASD. In particular, circadian sleep dysrhythmicity may predispose to develop ASD symptoms and vice versa within a self-reinforcing feedback loop. By targeting sleep disturbances and circadian sleep dysrhythmicity, we may improve treatment strategies for both children and adults with ASD.

Potentially traumatic events, post-traumatic stress disorder and post-traumatic stress spectrum in patients with fibromyalgia

OBJECTIVES

Fibromyalgia (FM) is defined as a severe, chronic, non-articular rheumatic condition characterised by widespread musculoskeletal pain, hyperalgesia and generalised tender points, in the absence of inflammatory or structural musculoskeletal abnormalities. Pain is the predominant symptom, allodynia and hyperalgesia are common signs. Extreme fatigue, impaired cognition and non-restorative sleeping difficulties coexist in addition to other somatic symptoms. Several studies suggest there is a meaningful relationship between FM and the psychological symptoms of depression and post-traumatic stress disorder (PTSD). PTSD is a mental disorder that can develop after a person has been exposed to a traumatic event, characterised by a specific set of symptoms including re-experiencing of the event, avoidance and numbing and arousal. The present study investigates the impact of lifetime potentially traumatic events, including losses, and of post-traumatic stress symptoms on the severity of illness in patients with fibromyalgia (FM).

METHODS

Sixty-one patients with FM, diagnosed according to the American College of Rheumatology criteria, were consecutively enrolled at the Unit of Rheumatology, University of Pisa, Italy. Assessments included: the SCID-5 and the Trauma and Loss Spectrum Self-Report (TALS-SR) lifetime version.

RESULTS

21.3% of the subjects (n=13) met the criteria for "partial" PTSD: 57.4% criterion B, 42.6% criterion C, 31.1 criterion D and 44.3% criterion E. Fibromyalgia patients without PTSD reported significantly lower scores in all domains compared to the patients with partial PTSD, the latter ones reporting significantly lower scores in all domains compared to full PTSD with the exception of domain I. In particular, these differences were noticeable in Domain VI and Domain VIII.

CONCLUSIONS

The results of the study show that fibromyalgic patients with PTSD report more potentially traumatic events, avoidance symptoms, numbing, arousal, maladaptive coping and personality characteristics compared to patients with partial or without PTSD; these results could indicate that loss and/or trauma events represent a risk factor for the development of symptoms of FM in genetically predisposed individuals.

Frequent attenders in general medical practice in Italy: a preliminary report on clinical variables related to low functioning

BACKGROUND

Frequent attenders (FAs), defined as patients reporting a disproportionate number of visits to general practitioners (GPs), may represent up to one-third of GP patients responsible for a high burden of care not always justified by the severity of the medical condition. The aim of this study was to explore sociodemographic and clinical characteristics of FAs of GP in Italy with particular attention to functional impairment.

METHODS

A total sample of 75 FAs (defined as individuals who had consulted GPs 15 times or more during 2015) of GPs of three primary care centers (Pisa, Livorno, and Lucca) in Italy were enrolled and assessed by sociodemographic scale, Structured Clinical Interview for DSM-5 (SCID-5), global functioning (Global Assessment of Functioning [GAF]), illness behavior and perceived health (Illness Behavior Inventory), and somatic comorbidity (Cumulative Illness Rating Scale).

RESULTS

Most of the sample were females, middle aged, married, or cohabiting, with low levels of education. One-third of FAs was low functioning (LF; GAF score <70), with no differences in the sociodemographic variables. Approximately 70.3% of the patients reported a current SCID diagnosis, in particular, major depressive disorder, somatic symptom disorders, and panic disorder, all being more frequent in LF patients. Half of the patients were taking a psychopharmacological therapy, mostly benzodiazepines (BDZs).

CONCLUSION

Most FAs were female with current medical disorders, and LF. All claimed to be worried about their own health and perceived themselves as more impaired also regarding the health perception and social role. LF patients were, or had been more likely to be under psychopharmacological treatment. FAs seem to constitute a special population that should be carefully evaluated for mental disorders and appropriate treatment.

Rumination, posttraumatic stress disorder, and mood symptoms in borderline personality disorder

Background: The interrelationship between mood disorders and borderline personality disorder (BPD) has been long debated in the literature. Increasing attention has also been paid to the relationship between posttraumatic stress disorder (PTSD) and BPD, as well as to the role of rumination in the development and severity of BPD. This study aims to evaluate the association of rumination, PTSD, and mood spectrum among patients with BPD with or without comorbid mood disorders. Methods: Fifty patients with BPD and 69 healthy controls were assessed with the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders 5, Mood Spectrum Self-Report (MOODS-SR), and Ruminative Response Scale (RRS). Results: The BPD group was split into subjects with BPD+ mood disorder (MD) or BPD only) . PTSD-criteria fulfillment, MOODS, and RRS scores were significantly higher in both BPD subgroups than in controls, while BPD+MD patients scored significantly higher than the BPD-only group. RRS scores and PTSD-criteria fulfillment were significantly related to the presence of both BPD and BPD+MD, with no effect of MOODS-SR scores. Conclusion: Our findings confirm the presence of a relationship between BPD and the PTSD spectrum, highlighting also a possible role of rumination in BPD psychopathology. Rumination and PTSD symptoms seem to prevail in the effect of mood spectrum in predicting BPD.

Personality Traits in Fibromyalgia (FM): Does FM Personality Exists? A Systematic Review

Introduction:

Fibromyalgia (FM) is the second most common rheumatic disease with many effects on patient's quality of life. It has been described as a chronic condition characterized by widespread musculo-skeletal pain, sleep disorders and prominent fatigue. Regarding the role of personality factors in fibromyalgia, researchers have focused both on personality traits and psychopathological aspects showing inconsistent results. In particular, several studies have examined the role of alexithymia in FM patients, a trait of personality characterized by difficulty in identification, recognition and description of emotions and feelings, while others have focused on a specific type of personality, such as type D personality (distressed personality). Other studies investigated personality in FM patients referring to Cloninger’s model, a psychobiological model of personality that includes both temperamental and character dimensions of personality. Analyzing scientific literature on this subject seems well suited to provide a critical review of the latest studies and their results.

Methods:

The method used for this review satisfies the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA). We identified PsycInfo and PubMed as databases for our research.

Results:

Personality is studied under many aspects and a reference model is not always present. Many studies underline high levels of alexithymia and type D personality in FM patients but when depression is controlled, these results do not differ from those of healthy controls.

Conclusion:

Studies that use a comprehensive model of personality present a different theoretical approach and use alternatively the Big-Five model, Eysenck’s and Cloninger’s models. The use of a comprehensive model of personality and the control of psychopathological disorders, such as anxiety and depression, seem to be very relevant for a better understanding of a specific personality profile associated with fibromyalgia.

Adult Autism Subthreshold Spectrum (AdAS Spectrum) in parents of pediatric patients with epilepsy: Correlations with post-traumatic stress symptoms

Increasing literature has shown the usefulness of a dimensional approach to mental disorders, particularly when exploring subjects exposed to traumatic experiences such as a severe illness in one's child. Recent evidence suggests an increased vulnerability in subjects with autism spectrum symptoms to develop post-traumatic stress symptoms. The aim of the present study was to evaluate the presence of adult autism subthreshold spectrum in a sample of parents of children with epilepsy and its impact on post-traumatic stress spectrum symptoms in the same study sample. Results revealed noteworthy correlations between post-traumatic stress symptoms and adult autism subthreshold spectrum (AdAS Spectrum) only in the subgroup of the fathers. In particular, were evidenced correlations between AdAS Spectrum domain of rumination and narrow interests and some TALS-SR nuclear domains: reaction to traumatic events, reexperiencing and arousal. These findings corroborate the hypothesis that subthreshold autistic features may influence the possible psychopathological reaction to trauma.

Correlates of autistic traits among patients with borderline personality disorder

BACKGROUND

Despite discrete autism-related dimensions, such as deficits in communication, empathy and mentalizing are likely to affect the development of personality and despite they actually frequently occur in borderline patients, no research has so far investigated the relationship between autistic traits and Borderline Personality Disorder (BPD). The objective of this study is to investigate the clinical significance of autistic traits in subjects with BPD.

METHODS

The sample included 50 patients with a clinical diagnosis of BPD and 69 healthy controls. The Structured Clinical Interview for DSM-5 Clinician Version was used to establish the presence of comorbid mental disorders among BPD subjects and to confirm the absence of lifetime mental disorders in the control group. Participants were also asked to fill three self-report instruments: the Adult Autism Subthreshold Spectrum (AdAS Spectrum), the Autism Spectrum Quotient (AQ) and the Mood Spectrum Self-Report (MOODS-SR).

RESULTS

Patients with BPD reported higher autistic traits than healthy individuals. Moreover, autistic traits were shown to exert a significant impact on some clinical features and associated manifestation of BPD, such as suicidality and lifetime exposure to physical and/or sexual abuse.

CONCLUSIONS

Subthreshold autism spectrum may be relevant for subjects suffering from BPD and future research may further address clinical correlates of autistic traits among patients with this disorder.

Management of psychiatric patients before deinstitutionalization: an inquiry into the years 1907-1913 in Pisa

Aim

Asylums comprises the main focus of historical research on early 20th century psychiatry. To assess the characteristic of asylum transfers in a clinical population, we analyzed newly found clinical records from University of Pisa Clinic for Mental and Nervous Illness. We focused on the early years of this structure’s activities considering all admissions from 24th April 1907 to 31st January 1913.

Methods

We collected demographic and clinical data from 1,068 patients performing Chi-Square Tests to study correlation between asylum transfer and diagnosis and gender difference; independent sample Student’s t-tests were also performed to compare mean Age, mean number of Days of Hospitalization and mean number of Subsequent Admissions to the Clinic observed in patients transferred to an asylum versus those who had been discharged. Multiple logistic regression model was employed to identify the best predictors of asylum transfers.

Results

Most patient were discharged, and only a third of the hospitalization led to asylum confinement. Our data outlines a peculiar discharge rationale, suggesting that the Clinic acted like a “sieve-institution” to prevent asylum overcrowding from treatable, non-chronic conditions.

Discussion

These data suggest that our historical view of psychiatric care is probably not complete, and that a different approach to source materials could provide new research paradigms.

Prevalence and characteristics of orthorexia nervosa in a sample of university students in Italy

AIMS

Orthorexia nervosa (ON) has been recently defined as a pathological approach to feeding related to healthiness concerns and purity of food and/or feeding habits. This condition recently showed an increasing prevalence particularly among young adults. In order to investigate the prevalence of ON and its relationship with gender and nutritional style among young adults, we explored a sample of students from the University of Pisa, Italy.

METHODS

Assessments included the ORTO-15 questionnaire and a socio-demographic and eating habits form. Subjects were dichotomized for eating habits (i.e. standard vs vegetarian/vegan diet), gender, parents' educational level, type of high school attended, BMI (low vs high vs normal BMI). Chi square tests were performed to compare rates of subjects with overthreshold ORTO-15 scores, and Student's unpaired t test to compare mean scores between groups. Two Classification tree analyses with CHAID growing method were employed to identify the variables best predicting ON and ORTO-15 total score.

RESULTS

more than one-third of the sample showed ON symptoms (ORTO-15 ≥ 35), with higher rates among females. Tree analyses showed diet type to predict ON and ORTO-15 total score more than gender.

CONCLUSIONS

Our results seem to corroborate recent data highlighting similarities between ON and anorexia nervosa (AN). We propose an interpretation of ON as a phenotype of AN in the broader context of Feeding and eating disorders (FEDs) spectrum.

Subthreshold autism spectrum disorder in patients with eating disorders

AIM

Increasingly data suggest a possible overlap between psychopathological manifestations of eating disorders (EDs) and autism spectrum disorders (ASD). The aim of the present study was to assess the presence of subthreshold autism spectrum symptoms, by means of a recently validated instrument, in a sample of participants with EDs, particularly comparing participants with or without binge eating behaviours.

METHODS

138 participants meeting DSM-5 criteria for EDs and 160 healthy control participants (HCs), were recruited at 3 Italian University Departments of Psychiatry and assessed by the SCID-5, the Adult Autism Subthreshold Spectrum (AdAS Spectrum) and the Eating Disorders Inventory, version 2 (EDI-2). ED participants included: 46 with restrictive anorexia (AN-R); 24 with binge-purging type of Anorexia Nervosa (AN-BP); 34 with Bulimia Nervosa (BN) and 34 with Binge Eating Disorder (BED). The sample was split in two groups: participants with binge eating behaviours (BEB), in which were included participants with AN-BP, BN and BED, and participants with restrictive behaviours (AN-R).

RESULTS

participants with EDs showed significantly higher AdAS Spectrum total scores than HCs. Moreover, EDs participants showed significantly higher scores on all AdAS Spectrum domains with the exception of Non verbal communication and Hyper-Hypo reactivity to sensory input for AN-BP participants, and Childhood/Adolescence domain for AN-BP and BED participants. Participants with AN-R scored significantly higher than participants with BEB on the AdAS Spectrum total score, and on the Inflexibility and adherence to routine and Restricted interest/rumination AdAS Spectrum domain scores. Significant correlations emerged between the Interpersonal distrust EDI-2 sub-scale and the Non verbal communication and the Restricted interest and rumination AdAS Spectrum domains; as well as between the Social insecurity EDI-2 sub-scale and the Inflexibility and adherence to routine and Restricted interest and rumination domains in participants with EDs.

CONCLUSIONS

Our data corroborate the presence of higher subthreshold autism spectrum symptoms among ED participants with respect to HCs, with particularly higher levels among restrictive participants. Relevant correlations between subthreshold autism spectrum symptoms and EDI-2 Subscale also emerged.

Exploring PTSD in emergency operators of a major University Hospital in Italy: a preliminary report on the role of gender, age, and education

BACKGROUND

Emergency services personnel face frequent exposure to potentially traumatic events, with the potential for chronic symptomatic distress. The DSM-5 recently recognized a particular risk for post-traumatic stress disorder (PTSD) among first responders (criterion A4) but data are still scarce on prevalence rates and correlates.

OBJECTIVE

The aim of the present study was to explore the possible role of age, gender, and education training in a sample of emergency personnel diagnosed with DSM-5 PTSD.

METHODS

The Trauma and Loss Spectrum-Self-Report (TALS-SR) and the Work and Social Adjustment Scale (WSAS) were administered to 42 between nurses and health care assistants, employed at the emergency room of a major University Hospital (Pisa) in Italy.

RESULTS

21.4% of the sample reported DSM-5 PTSD with significantly higher scores in the TALS-SR domain exploring the acute reaction to trauma and losses among health care assistants, older, and non-graduated subjects. A significant correlation between the number of the TALS-SR symptoms endorsed, corresponding to DSM-5 PTSD diagnostic criteria emerged in health care assistants.

CONCLUSIONS

Despite further studies are needed in larger samples, our data suggest a high risk for PTSD and post-traumatic stress spectrum symptoms in nurses and health care workers operating in an emergency department, particularly among health care assistants, women, older, and non-graduated operators.

Mothers and fathers of children with epilepsy: gender differences in post-traumatic stress symptoms and correlations with mood spectrum symptoms

BACKGROUND

Post-traumatic stress disorder (PTSD) and post-traumatic stress spectrum have been recently applied to understand the impact of life-threatening disease or injury in one's child; nevertheless, scant data are available on a particular chronic illness such as epilepsy whose phenotypic expression is seizures, which are acute, sudden, and unpredictable manifestations. Subjects with bipolar disorders or with mood spectrum symptoms demonstrated to be more vulnerable to develop PTSD in the aftermath of a trauma.

OBJECTIVES

The main aim of this study was to evaluate post-traumatic symptoms among 134 parents of children with a diagnosis of epilepsy, followed at the outpatient neurologic unit of Department of Pediatrics in Santa Chiara Hospital in Pisa, as well as gender differences. The second aim of this study was to estimate the impact of lifetime mood spectrum on post-traumatic stress symptoms in the same study sample after fulfillment of the Trauma and Loss Spectrum-Self Report (TALS-SR) and the Mood Spectrum-Self Report (MOODS-SR) lifetime version.

RESULTS

Results showed 10.4% and 37.3% of PTSD full and partial, respectively. Demographic characteristics and clinical features of the study sample did not show any impact on stress symptomatology. Mothers presented higher rates at all Diagnostic and Statistical Manual of Mental Disorders (DSM)-5 PTSD symptoms' clusters except avoidance. Nevertheless, noteworthy correlations between post-traumatic symptomatology and mood spectrum symptoms detected with the self-report tools, emerged only in the subgroup of the fathers.

CONCLUSION

These findings corroborate the need to provide assistance to caregivers of pediatric patients and confirm the hypothesis that lifetime mood spectrum may have an impact on reaction to traumas.

[Complicated Grief in DSM-5 era]

An increasing number of data has been recently focused on recognizing pathological grief reactions and on the distinction from physiological processes. Particularly, several studies have supported Complicated Grief (CG) as an independent disorder, in order to define the failure of spontaneous physiological mourning resolution. Upon these studies, the latest edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) with the name of "Persistent Complex Bereavement Disorder". This article aims at retracing the history of clinical research about the physiological and psychopathological processes related to grief and aims at presenting the main scientific studies that have described the features of the CG defining it as a distinct disorder. Similarities and distinctions among CG and Depression, Posttraumatic Stress Disorder and Adjustment Disorder were also reported.

Orthorexia nervosa in a sample of Italian university population

AIM

To investigate frequency and characteristics of orthorexic behaviours in a large university population.

METHODS

A total of 2826 individuals volunteered to complete an on-line anonymous form of ORTO-15 questionnaire, a self-administered questionnaire designed and validated to evaluate orthorexic symptomatology. As made in previous studies, an ORTO-15 total score lower than 35 has been used as an optimal threshold to detect a tendency to orthorexia nervosa. A specifically designed form was also used to collect socio-demographic variables.

RESULTS

Overall, 2130 students and 696 university employees belonging to University of Pisa (Italy) were assessed. Orthorexic features had a frequency of 32.7%. Females showed a significantly higher rate of over-threshold scores on ORTO-15, a lower BMI, a higher rate of underweight condition and of vegan/vegetarian nutrition style than males.

DISCUSSION

Orthorexia nervosa defined as a “fixation on healthy food”, is not formally present in DSM-5. The emergence of this condition as a new, possible prodromal of a psychological syndrome, has been recently emphasized by an increasing number of scientific articles. From our sample of university population emerged that being vegetarian or vegan, under-weight, female, student and being interested in the present study were significantly predictive of orthorexic tendency.

CONCLUSIONS

Our data contribute to define the new conceptualization of orthorexia nervosa. Further studies are warranted in order to explore the diagnostic boundaries of this syndrome, its course and outcome, and possible clinical implications.

Post-traumatic Stress Disorder in patients with ovarian cancer

Ovarian cancer (OC) is one of the deadliest malignancies. The impact of this diagnosis is, therefore, highly traumatic, and affected women are prone to significant distress during the whole course of the disease. The present paper is aimed to review extant literature about the relationship between OC and Post-traumatic Stress Disorder (PTSD).

The management of fibromyalgia from a psychosomatic perspective: an overview

Fibromyalgia (FM) is a central sensitization syndrome characterized by chronic widespread pain. FM is often comorbid with psychiatric disorders, as well as psychological distress that worsens the quality-of-life of people affected. The aim was to collect current evidence about the management of FM from a psychosomatic perspective. The literature was synthesized and summarized in a narrative format. The literature search was carried out in PubMed; review articles, meta-analysis, overview, and guidelines published in the last 10 years written in English were included. Five main topics (Diagnostic criteria of FM; Pathogenesis of chronic widespread pain in FM; Early stress and trauma as predisposing factors for central sensitization; FM and Psychiatric comorbidity; Implications for treatment) were pointed out and discussed. Much evidence underlies the importance of considering and treating the comorbidity of FM with psychiatric disorders and psychological factors that affect pain management. Validation of FM as a central sensitization syndrome by a clinician facilitates therapeutic strategies that involve patients as active participants in the pain management process, likely leading to improved outcomes.

New DSM-5 PTSD guilt and shame symptoms among Italian earthquake survivors: Impact on maladaptive behaviors

Important changes were introduced concerning posttraumatic-stress disorder (PTSD) by the DSM-5 recognizing the role of negative emotions such as guilt and shame, but little evidence is yet available on their prevalence in population assessed by means of DSM-5 criteria. In this study we explored the rates of guilt and shame DSM-5 PTSD diagnostic symptoms among Italian survivors to a massive earthquake and their possible correlation with PTSD and maladaptive behaviors. 869 residents of the town of L'Aquila exposed to the earthquake of April 6th, 2009 were investigated by the Trauma and Loss Spectrum-Self Report (TALS-SR) with particular attention to guilt and shame feelings. DSM-5 symptomatological PTSD was reported by 41.7% of survivors, further 11.6% endorsed at least one guilt/shame symptoms, with significantly higher rates of endorsement were in PTSD respect to No-PTSD subjects, and in the subgroup with at least one maladaptive behavior respect to those with none. There was a significant main effects of PTSD and at least one guilt/shame symptom on TALS-SR symptomatological domains. Mean TALS-SR Maladaptive coping domain score appeared significantly higher in the subgroup with at least one guilt/shame symptom. Further study are needed to investigate guilt and shame feelings in survivors to a natural disaster.

A Systematized Review of Atypical Antipsychotics in Pregnant Women: Balancing Between Risks of Untreated Illness and Risks of Drug-Related Adverse Effects

OBJECTIVE

To summarize risks related to (1) illness and (2) second-generation antipsychotic (SGA) treatment in pregnant women and their offspring. Concerning illness-related risks, we focused on bipolar disorder and schizophrenia, psychiatric disorders for which SGAs are preferentially prescribed.

DATA SOURCES

PubMed, Ovid, Scopus, PsycINFO, and Cochrane Library were searched from the date of the first available article to October 2015 using the following key terms: pregnancy OR gestation OR bipolar disorder OR schizophrenia. We also included cross-references from identified articles.

STUDY SELECTION

We included 49 English-language articles regarding illness-related and SGA-related risks in bipolar disorder and schizophrenia. First, searches were done for epidemiologic or experimental studies (from January 2000 to October 2015), then for systematic reviews and meta-analyses.

DATA EXTRACTION

Data were extracted independently, after removing duplicates and studies that were not relevant or not pertinent.

RESULTS

Abrupt discontinuation of treatment-exposed mothers with bipolar disorder or schizophrenia led to a high risk of relapses during pregnancy. Both bipolar disorder and schizophrenia were linked to a slightly increased risk of obstetric complications for mothers (schizophrenia) and the newborn (bipolar disorder and schizophrenia), although data on drug exposure during pregnancy were not given in the majority of studies. Maternal morbidity (schizophrenia but not bipolar disorder) may be associated with the worst neonatal outcomes (stillbirth, neonatal or infant deaths, and intellectual disability). Untreated bipolar disorder and schizophrenia may be considered independent risk factors for congenital malformations, while SGAs were not associated with increased recurring defects in fetuses. Evidence regarding the potential effects of SGAs on child neurodevelopment remains reassuring.

CONCLUSION

After taking into account the parents' will and after they provide informed consent, the most reasonable and less harmful choice for treating future mothers with bipolar disorder or schizophrenia appears to be maintaining them at the safest minimum dosage.

Autistic Traits in Patients with Anorexia Nervosa, Bulimia Nervosa or Binge Eating Disorder: A Pilot Study

Introduction

Previous data showed higher autistic traits in individuals with anorexia nervosa (AN) compared to healthy controls (CTL). It is not known, however, whether this characteristic is shared by other feeding and eating disorders (FEDs) or it is uniquely associated to AN.

Objectives

To compare autistic traits among individuals with AN, bulimia nervosa (BN), binge eating disorder (BED) and CTL and to investigate which specific dimensions differentiate one group from another.

Methods

A total of 241 FED patients (53 AN, 41 BN, 42 BED) and 105 CTL were administered the autism-spectrum quotient (AQ), the adult autism subthreshold spectrum (AdAS Spectrum), the Ritvo autism and Asperger diagnostic scale 14-item (RAADS-14 Screen).

Results

FED subjects reported higher AQ, AdAS spectrum and RAADS-14 total and subscales scores compared to CTL (all P < .001). No differences were found amongst AN, BN and BED subjects in questionnaires’ total scores. BN group scored higher than AN in the hyper-/hyporeactivity to sensory input domain of the AdAS spectrum (P < .001); AN group scored higher than BED in the attention switching domain of the AQ (P < .001), and BED group scored lower than both AN and BN in the mentalizing deficit domain of the RAADS-14 (all P < .001).

Conclusions

We reported for the first time that not only AN but also BN and BED patients show greater autistic traits compared to CTL. Longitudinal studies are needed to confirm this preliminary report and to elucidate whether autistic traits either precede, co-occur or follow FEDs.

Full and Partial DSM-5 PTSD in Parents of Children with Epilepsy: Exploring Gender Differences

Introduction

Increasing literature suggests the need to explore PTSD and post-traumatic stress symptoms among parents and caregivers of children with acute and chronic illnesses but scant data are available on epilepsy.

Objectives

The aim of this study was to estimate full and partial PTSD rates among parents of children with epilepsy according to DSM-5 criteria. Further, aim of this study was to examine eventual gender differences between mothers and fathers.

Methods

One hundred and thirty-eight parents, 91 mothers (65.9%) and 47 (34.1%) fathers, of children diagnosed with epilepsy were interviewed using the SCID-5.

Results

Full and partial DSM-5 PTSD were reported by 10.4% and 37.3% of patients, respectively. Significant gender differences, with the mother more affected, emerged in the rates of partial A PTSD rates (P = 0.048) and in the endorsement rates of criterion B (intrusion symptoms) (P = 0.047), criterion D (negative alterations in cognitions and mood) (P = 0.010) and criterion E (alterations in arousal and reactivity) (P < 0.001) too.

Conclusions

This is the first study to identify post-traumatic symptoms in caregivers of pediatric patients with epilepsy with the use of current diagnostic criteria and the relevance of the results suggests the need for further studies on this risk population.

Adult Autism Subthreshold Spectrum (AdAS Spectrum): Validation of a questionnaire investigating subthreshold autism spectrum

AIM

Increasing literature has shown the usefulness of a dimensional approach to autism. The present study aimed to determine the psychometric properties of the Adult Autism Subthreshold Spectrum (AdAS Spectrum), a new questionnaire specifically tailored to assess subthreshold forms of autism spectrum disorder (ASD) in adulthood.

METHODS

102 adults endorsing at least one DSM-5 symptom criterion for ASD (ASDc), 143 adults diagnosed with a feeding and eating disorder (FED), and 160 subjects with no mental disorders (CTL), were recruited from 7 Italian University Departments of Psychiatry and administered the following: SCID-5, Autism-Spectrum Quotient (AQ), Ritvo Autism and Asperger Diagnostic Scale 14-item version (RAADS-14), and AdAS Spectrum.

RESULTS

The AdAS Spectrum demonstrated excellent internal consistency for the total score (Kuder-Richardson's coefficient=.964) as well as for five out of seven domains (all coefficients>.80) and sound test-retest reliability (ICC=.976). The total and domain AdAS Spectrum scores showed a moderate to strong (>.50) positive correlation with one another and with the AQ and RAADS-14 total scores. ASDc subjects reported significantly higher AdAS Spectrum total scores than both FED (p<.001) and CTL (p<.001), and significantly higher scores on the Childhood/adolescence, Verbal communication, Empathy, Inflexibility and adherence to routine, and Restricted interests and rumination domains (all p<.001) than FED, while on all domains compared to CTL. CTL displayed significantly lower total and domain scores than FED (all p<.001). A significant effect of gender emerged for the Hyper- and hyporeactivity to sensory input domain, with women showing higher scores than men (p=.003). A Diagnosis* Gender interaction was also found for the Verbal communication (p=.019) and Empathy (p=.023) domains. When splitting the ASDc in subjects with one symptom criterion (ASD₁) and those with a ASD, and the FED in subjects with no ASD symptom criteria (FED₀) and those with one ASD symptom criterion (FED₁)_, a gradient of severity in AdAS Spectrum scores from CTL subjects to ASD patients, across FED₀, ASD₁, FED₁ was shown.

CONCLUSIONS

The AdAS Spectrum showed excellent internal consistency and test-retest reliability and strong convergent validity with alternative dimensional measures of ASD. The questionnaire performed differently among the three diagnostic groups and enlightened some significant effects of gender in the expression of autistic traits.

Adult separation anxiety disorder in complicated grief: an exploratory study on frequency and correlates

INTRODUCTION

Complicated grief (CG) has been the subject of increasing attention in the past decades but its relationship with separation anxiety disorder (SEPAD) is still controversial. The aim of the current study was to explore the prevalence and clinical significance of adult SEPAD in a sample of help-seeking individuals with CG.

METHODS

151 adults with CG, enrolled in a randomized controlled trial comparing the effectiveness of (CG) treatment to that of interpersonal therapy, were assessed by means of the Inventory of Complicated Grief (ICG), the Structured Clinical Interview for DSM-IV, the Hamilton Rating Scale for Depression (HAM-D), the Work and Social Adjustment Scale (WSAS), the Adult Separation Anxiety Questionnaire (ASA-27), the Grief Related Avoidance Questionnaire (GRAQ), the Peritraumatic Dissociative Experiences Questionnaire (PDEQ), and the Impact of Events Scale (IES).

RESULTS

104 (68.9%) individuals with CG were considered to have SEPAD (ASA-27 score ≥22). Individuals with SEPAD were more likely to have reported a CG related to the loss of another close relative or friend (than a parent, spouse/partner or a child) (p=.02), as well as greater scores on the ICG (p=<.001), PDEQ (p=.004), GRAQ (p<.001), intrusion (p<.001) and avoidance (p=<.001) IES subscales, HAM-D (p<.001) and WSAS (p=.006). ASA-27 total scores correlated with ICG (p<.0001), PDEQ (p<.001) GRAQ (p<.0001) scores and both the IES intrusion (p<.0001) and IES avoidance (p<.0001) subscale scores. People with SEPAD had higher rates of lifetime post-traumatic stress disorder (PTSD) (p=.04) and panic disorder (PD) (p=.01).

CONCLUSIONS

SEPAD is highly prevalent among patients with CG and is associated with greater symptom severity and impairment and greater comorbidity with PTSD and PD. Further studies will help to confirm and generalize our results and to determine whether adult SEPAD responds to CG treatment and/or moderates CG treatment response.

Depression, Serotonin and Tryptophan

Depression is a major cause of worldwide disability. Although its etiology is unclear, for over sixty years the study of its pathophysiology has focused mainly on serotonin (5-HT) and serotonergic neurotransmission. Generally, the study of the pathophysiological processes underpinning depression have led to the appreciation of its complexity, although such study continues to support the role of 5-HT in this disorder. The aim of this review is to briefly summarize the available findings on 5-HT and depression, with a special focus on alterations in tryptophan (TRP) metabolism that can shift from 5-HT synthesis towards other, potentially neurotoxic, compounds, such as the tryptophan catabolite, quinolinic acid. The evidence that the TRP shunt may be promoted by stress hormones and proinflammatory cytokines strongly supports the notion that depression should now be considered a systemic disorder that can be triggered by different factors that ultimately target the 5-HT system in vulnerable individuals. In addition, such intriguing findings suggest biochemical targets for novel treatment options in depression.

From Asperger's Autistischen Psychopathen to DSM-5 Autism Spectrum Disorder and Beyond: A Subthreshold Autism Spectrum Model

Growing interest has recently been devoted to partial forms of autism, lying at the diagnostic boundaries of those conditions previously diagnosed as Asperger's Disorder. This latter includes an important retrieval of the European classical psychopathological concepts of adult autism to which Hans Asperger referred in his work. Based on the review of Asperger's Autistische Psychopathie, from first descriptions through the DSM-IV Asperger's Disorder and up to the recent DSM-5 Autism Spectrum Disorder, the paper aims to propose a Subthreshold Autism Spectrum Model that encompasses not only threshold-level manifestations but also mild/atypical symptoms, gender-specific features, behavioral manifestations and personality traits associated with Autism Spectrum Disorder. This model includes, but is not limited to, the so-called broad autism phenotype spanning across the general population that does not fully meet Autism Spectrum Disorder criteria. From this perspective, we propose a subthreshold autism as a unique psychological/behavioral model for research that could help to understand the neurodevelopmental trajectories leading from autistic traits to a broad range of mental disorders.

Clinical correlates of plasma brain-derived neurotrophic factor in post-traumatic stress disorder spectrum after a natural disaster

Clinical correlates of plasma Brain-Derived Neurotrophic Factor (BDNF) have been investigated in a clinical population with Post Traumatic Stress Disorder (PTSD) symptoms and healthy control subjects who survived to the L'Aquila 2009 earthquake. Twenty-six outpatients and 14 control subjects were recruited. Assessments included: Structured Clinical Interview for DSM-IV Axis-I disorders Patient Version, Trauma and Loss Spectrum-Self Report (TALS-SR) for post-traumatic spectrum symptoms. Thirteen patients were diagnosed as Full PTSD and 13 as Partial PTSD. The subjects with full-blown PTSD showed lower BDNF level than subjects with partial PTSD and controls. Different relationship patterns of BDNF with post-traumatic stress spectrum symptoms have been reported in the three samples. Our findings add more insight on the mechanisms regulating BDNF levels in response to stress and further proofs of the utility of the distinction of PTSD into full and partial categories.

The Broad Autism (Endo)Phenotype: Neurostructural and Neurofunctional Correlates in Parents of Individuals with Autism Spectrum Disorders

Autism Spectrum Disorders (ASD) are a set of neurodevelopmental disorders with an early-onset and a strong genetic component in their pathogenesis. According to genetic and epidemiological data, ASD relatives present personality traits similar to, but not as severe as the defining features of ASD, which have been indicated as the "Broader Autism Phenotype" (BAP). BAP features seem to be more prevalent in first-degree relatives of individuals with ASD than in the general population. Characterizing brain profiles of relatives of autistic probands may help to understand ASD endophenotype. The aim of this review was to provide an up-to-date overview of research findings on the neurostructural and neurofunctional substrates in parents of individuals with ASD (pASD). The primary hypothesis was that, like for the behavioral profile, the pASD express an intermediate neurobiological pattern between ASD individuals and healthy controls. The 13 reviewed studies evaluated structural magnetic resonance imaging (MRI) brain volumes, chemical signals using magnetic resonance spectroscopy (MRS), task-related functional activation by functional magnetic resonance imaging (fMRI), electroencephalography (EEG), or magnetoencephalography (MEG) in pASD.The studies showed that pASD are generally different from healthy controls at a structural and functional level despite often not behaviorally impaired. More atypicalities in neural patterns of pASD seem to be associated with higher scores at BAP assessment. Some of the observed atypicalities are the same of the ASD probands. In addition, the pattern of neural correlates in pASD resembles that of adult individuals with ASD, or it is specific, possibly due to a compensatory mechanism. Future studies should ideally include a group of pASD and HC with their ASD and non-ASD probands respectively. They should subgrouping the pASD according to the BAP scores, considering gender as a possible confounding factor, and correlating these scores to underlying brain structure and function. These types of studies may help to understand the genetic mechanisms involved in the various clinical dimension of ASD.

Historical evolution of the concept of anorexia nervosa and relationships with orthorexia nervosa, autism, and obsessive-compulsive spectrum

Eating disorders have been defined as "characterized by persistence disturbance of eating or eating-related behavior that results in the altered consumption or absorption of food and that significantly impairs health or psychosocial functioning". The psychopathology of eating disorders changed across time under the influence of environmental factors, determining the emergence of new phenotypes. Some of these conditions are still under investigation and are not clearly identified as independent diagnostic entities. In this review, the historic evolution of the eating disorder concept up to the recent Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, has been evaluated. We also examined literature supporting the inclusion of new emergent eating behaviors within the eating disorder spectrum, and their relationship with anorexia, autism, and obsessive-compulsive disorder. In particular, we focused on what is known about the symptoms, epidemiology, assessment, and diagnostic boundaries of a new problematic eating pattern called orthorexia nervosa that could be accepted as a new psychological syndrome, as emphasized by an increasing number of scientific articles in the last few years.

Impact of Mood Spectrum Spirituality and Mysticism Symptoms on Suicidality in Earthquake Survivors with PTSD

The aim of the present study was to explore the correlations between Spirituality/Mysticism/Psychoticism symptoms and suicidality in young adult survivors of the L'Aquila earthquake. The sample included 475 subjects recruited among high school seniors who had experienced the April 6, 2009, earthquake. Assessments included: Trauma and Loss Spectrum-Self Report and Mood Spectrum-Self Report (MOODS-SR). Mysticism/Spirituality dimension and suicidality were evaluated by means of some specific items of the MOOD-SR. The Spirituality/Mysticism/Psychoticism MOODS-SR factor score was significantly higher among subjects with PTSD diagnosis with respect to those without. Similarly, subjects with suicidal ideation, as well as those who committed a suicide attempt, reported significantly higher scores than those without.

Transdiagnostic factors across fibromyalgia and mental disorders: sleep disturbances may play a key role. A clinical review

Sleep disturbances, affective disorders, pain and fatigue are often present in individuals affected by fibromyalgia (FM). The pathophysiology of FM is not yet well understood and, to date, no treatment has been proven to be fully effective in alleviating all symptoms. Adopting a transdiagnostic perspective could thus be useful for clinicians: treatment would target a transdiagnostic process across a range of disturbances, not just a single disorder. The aim of this review is to revise the available literature about the potential role of sleep disturbances as a transdiagnostic process in FM symptomatology and mood or anxiety disorders comorbidity. We are proposing a model under which sleep disturbances can play a central role. Because conditions of sleep loss are related to the activation of the stress system, including the activation of the inflammation system, we propose this mechanism as a key one: it can be shared by mental, sleep disturbances and pain in FM and it may explain, in part, the high levels of comorbidity between them. In this frame-work sleep disturbances may play a key role and be the target of therapeutic strategies across FM symptomatology and mental disorders.

DSM-5 PTSD and posttraumatic stress spectrum in Italian emergency personnel: correlations with work and social adjustment

The Diagnostic and Statistical Manual of Mental Disorders Fifth Edition (DSM-5) has recently recognized a particular risk for posttraumatic stress disorder (PTSD) among first responders (criterion A4), acknowledging emergency units as stressful places of employment. Little data is yet available on DSM-5 among emergency health operators. The aim of this study was to assess DSM-5 symptomatological PTSD and posttraumatic stress spectrum, as well as their impact on work and social functioning, in the emergency staff of a major university hospital in Italy. One hundred and ten subjects (doctors, nurses, and health-care assistants) were recruited at the Emergency Unit of the Azienda Ospedaliero-Universitaria Pisana (Italy) and assessed by the Trauma and Loss Spectrum-Self Report (TALS-SR) and Work and Social Adjustment Scale (WSAS). A 15.7% DSM-5 symptomatological PTSD prevalence rate was found. Nongraduated persons reported significantly higher TALS-SR Domain IV (reaction to loss or traumatic events) scores and a significantly higher proportion of individuals presenting at least one maladaptive behavior (TALS-SR Domain VII), with respect to graduate ones. Women reported significantly higher WSAS scores. Significant correlations emerged between PTSD symptoms and WSAS total scores among health-care assistants, nongraduates and women. Our results showed emergency workers to be at risk for posttraumatic stress spectrum and related work and social impairment, particularly among women and nongraduated subjects.

Psychotic spectrum symptoms across the lifespan are related to lifetime suicidality among 147 patients with bipolar I or major depressive disorder

BACKGROUND

Conflicting evidence exists about the relationship between psychotic symptoms and suicidality in mood disorders. We aimed to investigate the lifetime suicidality and its relationship with dimensions of the psychotic spectrum over the lifespan among subjects with bipolar I (BD I) or major depressive disorder (MDD).

METHODS

147 Consecutive out- and inpatients with BD I or MDD presenting for treatment at 11 Italian Departments of Psychiatry were administered the Structured Clinical Interview for DSM-IV Axis I Disorders, the Structured Clinical Interview for the Psychotic Spectrum (SCI-PSY, lifetime version) and the Mood Spectrum Self-Report (MOODS-SR, lifetime version).

RESULTS

Subjects with psychotic features did not differ from those without for MOODS-SR suicidality score. Controlling for age, gender and diagnosis (MDD/BD I), the SCI-PSY total score (p = .007) and Paranoid (p = .042), Schizoid (p = .007) and Interpersonal Sensitivity (p < .001) domain scores independently predicted lifetime MOODS-SR suicidality score in the overall sample.

CONCLUSIONS

Psychotic features, as evaluated upon the presence of delusions or hallucinations, are not associated with suicidality among subjects with BD I or MDD. However, more subtle dimensions of the psychotic spectrum, such as Interpersonal Sensitivity, Paranoid and Schizoid symptoms, show a significant relationship with lifetime suicidality. Our findings highlight the potential usefulness of a spectrum approach in the assessment of psychotic symptoms and suicide risk among subjects with BD I or MDD.

A new look at an old drug: neuroprotective effects and therapeutic potentials of lithium salts

Increasing evidence highlights bipolar disorder as being associated with impaired neurogenesis, cellular plasticity, and resiliency, as well as with cell atrophy or loss in specific brain regions. This has led most recent research to focus on the possible neuroprotective effects of medications, and particularly interesting findings have emerged for lithium. A growing body of evidence from preclinical in vitro and in vivo studies has in fact documented its neuroprotective effects from different insults acting on cellular signaling pathways, both preventing apoptosis and increasing neurotrophins and cell-survival molecules. Furthermore, positive effects of lithium on neurogenesis, brain remodeling, angiogenesis, mesenchymal stem cells functioning, and inflammation have been revealed, with a key role played through the inhibition of the glycogen synthase kinase-3, a serine/threonine kinase implicated in the pathogenesis of many neuropsychiatric disorders. These recent evidences suggest the potential utility of lithium in the treatment of neurodegenerative diseases, neurodevelopmental disorders, and hypoxic-ischemic/traumatic brain injury, with positive results at even lower lithium doses than those traditionally considered to be antimanic. The aim of this review is to briefly summarize the potential benefits of lithium salts on neuroprotection and neuroregeneration, emphasizing preclinical and clinical evidence suggesting new therapeutic potentials of this drug beyond its mood stabilizing properties.

Unexpected subthreshold autism spectrum in a 25-year-old male stalker hospitalized for delusional disorder: a case report

This paper highlights the clinical challenges faced when assessing patients with stalking behaviors with psychotic disorders, suggesting the need for an accurate assessment of adult autism spectrum symptoms. A 25-year-old man with a diagnosis of delusional disorder, erotomanic type, was hospitalized for acute psychotic symptoms occurred in the framework of a repeated stalking behavior towards his ex girlfriend. When assessed for adult autism spectrum symptoms upon an accurate clinical evaluation, he reported elevated scores in the mentalizing deficit and social anxiety domains by means of the 14 item Ritvo Autism and Asperger Diagnostic Scale (RAADS-14). Authors discuss a possible role of adult (subthreshold) autism spectrum symptoms, generally disregarded in adult psychiatry, on the type of psychotic features and stalking behavior developed that may help for appropriate diagnosis and treatment.

Adult separation anxiety differentiates patients with complicated grief and/or major depression and is related to lifetime mood spectrum symptoms

BACKGROUND

Increasing literature has been focused on complicated grief (CG) and its distinctiveness from other potentially loss related mental disorders such as major depression (MD). In this regard, symptoms of separation distress seem to play a key role. The aim of this study was to compare the clinical features of CG to those of MD and of CG+MD, with particular attention to separation anxiety.

METHODS

Fifty patients with CG (26 with and 24 without MD) and 40 with MD were consecutively recruited. Assessments included: SCID-I/P, Inventory of Complicated Grief (ICG), Adult Separation Anxiety Symptom Questionnaire (ASA-27), Work and Social Adjustment Scale (WSAS), Mood Spectrum-Self Report (MOODS-SR)-lifetime version.

RESULTS

Patients with MD reported significantly higher ASA-27 scores than patients with CG either alone or with MD. In all groups, ASA-27 total scores were significantly correlated with the MOODS-SR total scores and with those of its depressive component and rhythmicity domain. No significant differences were reported in the WSAS scores.

LIMITATIONS

Major limitations are the small sample size and the use of lifetime instruments.

CONCLUSIONS

Our results suggest a correlation between adult separation anxiety symptoms and lifetime mood spectrum symptoms both in patients with CG and MD. Further studies are needed to better understand the role of adult separation anxiety in the development of these disorders and for their nosographic autonomy as well.

Interferon α Therapy in Patients with Chronic Hepatitis C Infection: Quality of Life and Depression

Health-related quality of life was examined in 49 patients with hepatitis C virus with no psychiatric history who received interferon (IFN)-α treatment. Quality of life was assessed at baseline, at 3-time points during IFN-α therapy and at 1-6 month follow-up, using SF-36. Hepatitis C virus patients showed poorer physical functioning and better social and mental functioning than a normal population. Significant decreases from baseline SF-36 scores were observed at an early phase of treatment. Six patients developed major depression during IFN-α treatment. At baseline, they had reported more bodily pain than patients who did not develop depression during treatment. Planned contrasts revealed that worsening in some dimensions of quality of life at 2 months was greater in depressed than in non-depressed patients. Results suggest that depressive symptoms should be accurately monitored during IFN-α therapy even in patients with no psychiatric history, especially if they present with bodily pain.

Bridging the gap between education and appropriate use of benzodiazepines in psychiatric clinical practice

More than half a century after their discovery, benzodiazepines (BDZs) still represent one of the largest and most widely prescribed groups of psychotropic compounds, not only in clinical psychiatry but also in the entire medical field. Over the last two decades, however, there has been an increased focus on the development of antidepressants and antipsychotics on the part of the pharmaceutical industry, clinicians, and researchers, with a reduced interest in BDZs, in spite of their widespread clinical use. As a consequence, many psychiatric residents, medical students, nurses, and other mental health professionals might receive poor academic teaching and training regarding these agents, and have the false impression that BDZs represent an outdated chapter in clinical psychopharmacology. However, recent advances in the field, including findings concerning epidemiology, addiction risk, and drug interactions, as well as the introduction of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition with related diagnostic changes, strongly encourage an updated appraisal of the use of BDZs in clinical practice. During a recent thematic event convened with the aim of approaching this topic in a critical manner, a group of young Italian psychiatrists attempted to highlight possible flaws in current teaching pathways, identify the main clinical pros and cons regarding current use of BDZs in clinical practice, and provide an updated overview of their use across specific clinical areas and patient populations. The main results are presented and discussed in this review.

The inflammatory hypothesis of mood spectrum broadened to fibromyalgia and chronic fatigue syndrome

OBJECTIVES

The present paper aimed at reviewing literature data on the inflammatory hypothesis of mood spectrum, as well as the overlapping features with some chronic rheumatologic disorders, in particular fibromyalgia and chronic fatigue syndrome.

METHODS

A literature search was carried out for English papers published in the years 2000-2014, while using the following words: mood spectrum, depression, bipolar disorders, fibromyalgia, chronic fatigue syndrome, neurotransmitters, inflammation, neuroinflammation, cytokines.

RESULTS

Overlapping features were highlighted between mood spectrum, fibromyalgia and chronic fatigue syndrome suggesting common underlying mechanisms at pathophysiological level involving both central nervous and the immune systems.

CONCLUSIONS

Taken together, the literature would suggest that the borders between different medical domains should be reconsidered in the light of common processes linking them.

Frequency of trauma exposure and Post-Traumatic Stress Disorder in Italy: analysis from the World Mental Health Survey Initiative

Epidemiological studies have examined the relative importance of Traumatic Events (TEs) in accounting for the societal burden of post-traumatic stress disorder (PTSD). However, most studies used the worst trauma experienced, which can lead to an overestimation of the conditional risk of PTSD. Although a number of epidemiological surveys on PTSD have been carried out in the United States, only a few studies in limited sample have been conducted in Italy. This study, carried out in the framework of the World Mental Health Survey Initiative, is a cross-sectional household survey of a representative sample of the Italian adult population. Lifetime prevalence of TEs and 12-month prevalence of PTSD were evaluated using the Composite International Diagnostic Interview (CIDI). Reports of PTSD associated with randomly selected TEs were weighted by the individual-level probabilities of TE selection to generate estimates of population-level PTSD risk associated with each TE. Network events was the most commonly reported class of TEs (29.4%). War events had the highest conditional risk of PTSD (12.2%). The TEs that contributed most to societal PTSD burden were unexpected death of a loved one (24.1%) and having seen atrocities (18.2%). Being female was related to high risk of PTSD after experiencing a TE. Exposure to network events is commonly reported among Italian adults, but two TEs are responsible for the highest burden associated with PTSD: the unexpected death of someone close and sexual assault. These results can help designing public health interventions to reduce the societal PTSD burden.

The adolescent emotional coping after an earthquake: a risk factor for suicidal ideation

The study aims to investigate the relationship of suicidal ideation with coping and resilience in a sample of adolescents who survived an earthquake. Three hundred forty-three adolescents who had experienced the L'Aquila earthquake were investigated for a screening distinguishing Suicidal Screen-Negative (SSN) from the Positive (SSP) subjects. Resilience Scale for Adolescents (READ) and Brief Cope were administered. Emotion-focused coping score was significantly higher in SSP subjects. In the SSN but not in the SSP sample the READ total score correlated with problem-focused total score. A positive correlation was seen between emotion-focused and problem-focused scores in both samples, with a higher coefficient in SSP sample. Externalising problems and maladaptive behaviours can arise in adolescents exposed to traumatic events. Attention should be paid in reducing risk factors and in the development of psychological abilities, improving the coping strategies that can protect from emotional despair and suicidal ideation.

Gender differences in DSM-5 versus DSM-IV-TR PTSD prevalence and criteria comparison among 512 survivors to the L'Aquila earthquake

BACKGROUND

Post-traumatic Stress Disorder (PTSD) has demonstrated gender-specific prevalence and expressions across the different DSM definitions, since its first introduction in DSM-III. The DSM-5 recently introduced important revisions to PTSD symptomatological criteria. Aim of the present study is to explore whether gender moderates rates of DSM-5 PTSD expression in a non-clinical sample of survivors to a massive earthquake in Italy.

METHODS

512 survivors of the L'Aquila 2009 earthquake, previously investigated for the presence DSM-IV-TR PTSD, were reassessed according to DSM-5 criteria in order to explore gender differences. All subjects completed the Trauma and Loss Spectrum-Self Report (TALS-SR).

RESULTS

Females showed significantly higher DSM-5 PTSD rates and rates of endorsement of almost all DSM-5 PTSD criteria. Significant gender differences emerged in almost half of PTSD symptomatological criteria with women reporting higher rates in 8 of them, while men in only one (a new symptom in DSM-5: reckless or self-destructive behavior). Considering the impact of the three new DSM-5 symptoms on the diagnosis, significant gender differences emerged with these being crucial in almost half of the PTSD diagnoses in males but in about one-fourth in females. By using ROC curves, DSM-5 criteria E and D showed the highest AUC values in males (.876) and females (.837), respectively.

LIMITATIONS

The use of self-report instrument; no information on comorbidity; homogeneity of study sample; lack of assessment on functional impairment.

CONCLUSIONS

This study provides a contribution to the ongoing need for reassessment on how gender moderates rates of expression of particular disorders such as PTSD.

Lifetime mania is related to post-traumatic stress symptoms in high school students exposed to the 2009 L'Aquila earthquake

BACKGROUND

Bipolar patients seem to be at high risk of trauma exposure and, when exposed, of PTSD. When comorbid, PTSD has shown a negative impact on the course of the bipolar illness. Conversely, a correlation between even manic symptoms and an increased risk for suicide has also been reported in PTSD patients. The aim of this study was to investigate the relationships between lifetime mood spectrum symptoms and PTSD in a sample of earthquake survivors.

METHODS

A total of 475 young adults who survived the L'Aquila 2009 earthquake, 21months earlier, were assessed by the Moods Spectrum-Self Report (MOODS-SR) and the Trauma and Loss Spectrum Self Report (TALS-SR).

RESULTS

Significantly higher MOODS-SR and TALS-SR domain scores were found in PTSD survivors compared to those without. The mood depressive (O.R.=1.17, 95% CI: 1.10-1.25), cognition depressive (O.R.=1.07, 95% CI: 1.01-1.14) and energy manic (O.R.=1.13, 95% CI: 1.02-1.25) MOODS-SR domains were significantly associated with an increased likelihood of PTSD.

CONCLUSIONS

Our data corroborate the strong relationship between mood disorder and PTSD highlighting a relationship between lifetime depressive and manic symptoms and PTSD, with a particular impact of the latter on the number of traumatic exposures and maladaptive behaviors.

Post-traumatic stress disorder in DSM-5: estimates of prevalence and criteria comparison versus DSM-IV-TR in a non-clinical sample of earthquake survivors

BACKGROUND

The latest edition of DSM (DSM-5) introduced important revisions to PTSD symptomatological criteria, such as a four-factor model and the inclusion of new symptoms. To date, only a few studies have investigated the impact that the proposed DSM-5 criteria will have on prevalence rates of PTSD.

METHODS

An overall sample of 512 adolescents who survived the L'Aquila 2009 earthquake and were previously investigated for the presence of full and partial PTSD, using DSM-IV-TR criteria, were reassessed according to DSM-5 criteria. All subjects completed the Trauma and Loss Spectrum-Self Report (TALS-SR).

RESULTS

A DSM-5 PTSD diagnosis emerged in 39.8% of subjects, with a significant difference between the two sexes (p<0.001), and an overall 87.1% consistency with DSM-IV-TR. Most of the inconsistent diagnoses that fulfilled DSM-IV-TR criteria but not DSM-5 criteria can be attributed to the subjects not fulfilling the new criterion C (active avoidance). Each DSM-5 symptom was more highly correlated with its corresponding symptom cluster than with other symptom clusters, but two of the new symptoms showed moderate to weak item-cluster correlations. Among DSM-5 PTSD cases: 7 (3.4%) endorsed symptom D3; 151 (74%) D4; 28 (13.7%) both D3 and D4; 75 (36.8%) E2.

LIMITATIONS

The use of a self-report instrument; no information on comorbidity; homogeneity of study sample; lack of assessment on functional impairment; the rates of DSM-IV-TR qualified PTSD in the sample was only 37.5%.

CONCLUSIONS

This study provides an inside look at the empirical performance of the DSM-5 PTSD criteria in a population exposed to a natural disaster, which suggests the need for replication in larger epidemiological samples.

Cyclic adenosine monophosphate responsive element binding protein in post-traumatic stress disorder

OBJECTIVES

The cyclic adenosine monophosphate responsive element binding (CREB) protein is a transcription factor involved in different neural processes, such as learning, neuroplasticity and the modulation of stress response. Alterations in the CREB pathway have been observed in the brains and lymphocytes of patients affected by depression and alcohol abuse. Given the lack of information, our study aimed at investigating the levels of total and activated CREB protein in lympho-monocytes of 20 drug-free patients suffering from post-traumatic stress disorders (PTSD), as compared with 20 healthy control subjects.

METHODS

Blood samples were collected from patients and healthy control subjects on the same time and lympho-monocytes were isolated according to standardized methods. CREB protein levels and activation were measured by means of immunoenzymatic techniques.

RESULTS

The results showed that PTSD patients had statistically lower levels of total CREB protein in lympho-monocytes than healthy control subjects. On the contrary, no difference in the activated CREB protein was detected.

CONCLUSIONS

These findings, albeit preliminary, would suggest that the CREB pathway might be involved in the pathophysiology of PTSD. Future studies should clarify if specific PTSD symptom clusters might be related to the CREB pathway.

Sexual obsessions and suicidal behaviors in patients with mood disorders, panic disorder and schizophrenia

BACKGROUND

The topic of sexual obsessions as a psychiatric symptom has not been well investigated. The aim of this study was twofold: 1) to explore the presence of sexual obsessions in patients with mood disorders (n=156), panic disorder (n=54) and schizophrenia (n=79), with respect to non-psychiatric subjects (n=100); 2) to investigate the relationship between sexual obsessions and suicidal behaviors, taking into account socio-demographic variables ad mental disorders.

METHODS

289 psychiatric patients with mood disorders, panic disorder or schizophrenia, were recruited at the Italian University departments of psychiatry along with 100 non-psychiatric subjects, who presented for a routine eye exam at the ophthalmology department of the same Universities. The assessments included: the Structured Clinical Interview for DSM-IV-TR, the Brief Psychiatric Rating Scale (BPRS), the Obsessive-Compulsive Spectrum Self-Report (OBS-SR), for sexual obsession, and the Mood Spectrum-Self Report lifetime version (MOODS-SR). Suicidality was assessed by means of 6 items of the MOODS-SR.

RESULTS

Sexual obsessions were more frequent in schizophrenia (54.4%), followed by mood disorders (35.9%). Among schizophrenia patients, males reported more sexual obsessions than females (P<0.01). Subjects who were more likely to report suicidal behaviors (suicidal ideation, plans and attempts) were female (adjusted OR=1.99), patients with mental disorders, specifically mood disorders (adjusted OR=11.5), schizophrenia (adjusted OR=3.7) or panic disorder (adjusted OR=2.9), and subjects who reported lifetime sexual obsessions (adjusted OR= 3.6). Sexual obsessions remained independently associated with all aspects of suicidal behaviors. Age, education, marital and employment status were not related to suicidal behaviors.

CONCLUSIONS

Special attention should be given to investigate and establish effective strategies of treatment for sexual obsessions, especially those with comorbid mood disorders or schizophrenia.

Lifetime mood symptoms and adult separation anxiety in patients with complicated grief and/or post-traumatic stress disorder: a preliminary report

A minority of bereaved individuals experiences symptoms of complicated grief (CG) that are associated with significant distress and impairment. CG is currently under consideration for inclusion in the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-V) and a major issue is whether or not it can be differentiated from major depressive disorder (MDD) and post-traumatic stress disorder (PTSD). The purpose of this study is to compare the clinical features of CG with those of PTSD and CG+PTSD. A total sample of 116 patients (66 PTSD, 22 CG and 28 CG+PTSD) was recruited. Assessments included: Structured Clinical Interview for DSM-IV Axis-I disorders (SCID-I/P), Inventory of Complicated Grief (ICG), Adult Separation Anxiety Questionnaire (ASA-27), Work and Social Adjustment Scale (WSAS), and Mood Spectrum-Self Report (MOODS-SR) lifetime version. CG was strongly associated with female gender. MDD comorbidity was more common among patients with CG while bipolar disorder was highest among those with PTSD+CG. Patients with CG+PTSD reported significantly higher ASA-27 scores compared to patients with either CG or PTSD alone. Patients with CG+PTSD or PTSD alone reported significantly higher scores on the manic component of the MOODS-SR. No significant differences were reported in the WSAS scores. Our results support differences between CG and PTSD that are important for the consideration of including CG as a new disorder in the DSM-V.

A link between oxytocin and serotonin in humans: supporting evidence from peripheral markers

Pharmacological studies indicate a functional interaction between the serotonergic and oxytocinergic systems. In particular, some selective serotonin (5-HT) reuptake inhibitors, such as citalopram and fluvoxamine, seem to exert part of their antidepressant effects through oxytocin (OT) release. Further, the administration of fenfluramine, a serotonergic agonist, to healthy subjects increases plasma OT levels. Interestingly, immunocytochemical and double-immunofluorescent techniques revealed a high degree of overlap between 5-HT transporter (SERT)-labeled fibers and OT-containing cells in the paraventricular and supraoptic nuclei of primate hypothalamus. These findings suggest that the influence of 5-HT on OT system might be mediated by SERT. In this study, we explored the possible existence of a link between OT and SERT in human subjects, by means of two peripheral markers, the platelet SERT, as measured by [³H]-paroxetine ([³H]-Par) binding, and plasma OT levels. As far as [³H]-Par binding parameters are concerned, the Bmax (mean ± SD, fmol/mg protein) was 1155 + 130 and the Kd (mean ± SD, nM) was 1.31 ± 0.61. The OT plasma levels (mean ± SD, pg/ml) were 1.14 ± 1.07. A significant and positive correlation was found between plasma OT levels and Kd values (correlation coefficient: r: 0.466, p = .038). This result represents the first evidence of an interaction between OT and SERT, as measured by [³H]-Par binding, at peripheral levels in humans. Given the several activities mediated by both OT and 5-HT, such a relationship might provide new perspectives and insights into psychiatric disorders and/or social relationship disturbances, as well as novel treatment strategies overcoming and/or integrating the serotonergic paradigm.
