The Expression of Affective Temperaments in Cystic Fibrosis Patients: Psychopathological Associations and Possible Neurobiological Mechanisms. Brain Sci 2023; 13:brainsci13040619. [PMID: 37190584 DOI: 10.3390/brainsci13040619] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2023] [Revised: 04/03/2023] [Accepted: 04/03/2023] [Indexed: 04/09/2023] Open
Abstract
The aim of this study was to investigate the association between Cystic Fibrosis (CF) and affective temperaments, considering the relevance of ionic balances in neural excitability, as a possible neurobiological basis for temperamental expression. A cross-sectional study involving 55 adult CF patients was conducted. Sociodemographic, clinical and therapeutic characteristics, temperamental and personality dispositions and depressive and anxiety symptoms were evaluated through standardized semi-structured and structured interviews. The majority of the enrolled CF patients were receiving Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) therapy (72.7%), and most of them had hyperthymic temperament predominance (29.1%). Different TEMPS-A (Temperament Evaluation of Memphis, Pisa, Paris, and San Diego Autoquestionnaire) dimensions were not associated with the type of CF phenotype-related mutation or with the use of CFTR-modulator therapy. However, a tendency towards irritability was noted in patients not undergoing CFTR modulator therapy (6.7 ± 4.72 vs. 4.7 ± 4.33; p = 0.13). In light of the limitations imposed by the cross-sectional nature of the study, a hyperthymic temperament was found to be protective against current or lifetime psychopathologic events, whereas the other temperaments were associated with positive psychopathological anamnesis. Based on the measurement of temperament profiles and the study of their associations with clinically relevant variables, we argue that subjecting CF patients to such a temperament assessment could prove beneficial in the transition towards integrated and personalized care.

Abstract
OBJECTIVE Psychiatric disorders are very common in patients affected by Parkinson's disease (PD). However, comorbidity with Bipolar Spectrum disorders is understudied. The aim of this study is to explore the clinical correlates of PD associated with Bipolar Spectrum disorders. METHODS One hundred PD patients were screened for psychiatric comorbidities, cognitive profile, motor, and non-motor symptoms. The sample was divided into three groups: PD-patients with Bipolar Spectrum disorders (bipolar disorder type I, type II, and spontaneous or induced hypomania; N = 32), PD-patients with others psychiatric comorbidities (N = 39), PD-patients without psychiatric comorbidities (N = 29). Clinical features were compared among the groups using analysis of variance and chi-square test. A logistic regression was performed to evaluate the association between Bipolar Spectrum disorders and early onset of PD (≤50 years) controlling for lifetime antipsychotic use. RESULTS In comparison with PD patients with and without other psychiatric comorbidity, subjects affected by Bipolar Spectrum disorders were younger, showed more frequently an early onset PD, reported more involuntary movements and a higher rate of impulse control disorders and compulsive behaviors. No differences were observed in indexes of exposure to dopamine agonist treatments. The early onset of PD was predicted by Bipolar Spectrum comorbidity, independently from lifetime antipsychotic use. CONCLUSION Bipolar Spectrum disorders are common in early onset PD. The presence of bipolar comorbidity could identify a particular subtype of PD, showing higher rates of neurological and psychiatric complications and deserving further investigation.

Abstract
Mood and anxiety disorders are the most common neuropsychiatric syndromes associated with Parkinson's disease (PD). The aim of our study was to estimate the prevalence of lifetime and current anxiety disorders in patients with Parkinson's Disease (PD), to explore possible distinctive neurological and psychiatric features associated with such comorbidity. One hundred patients were consecutively recruited at the Movement Disorders Section of the Neurological Outpatient Clinic of the University of Pisa. According to the MINI-Plus 5.0.0, 41 subjects were diagnosed with lifetime anxiety disorder (22 with panic disorder) and 26 were diagnosed with current anxiety disorders. Patients with anxiety disorders were more frequently characterized by psychiatric symptoms preceding PD, lifetime major depression and antidepressant treatments. They showed more anxious temperamental traits and scored higher at Parkinson Anxiety Scale (PAS) and persistent anxiety subscale. Current anxiety disorders were associated with more severe psychopathology, depressive symptomatology, and avoidant behavior. Among anxiety subtypes, patients with lifetime panic disorder showed higher rates of psychiatric symptoms before PD, lifetime unipolar depression, current psychiatric treatment, and a more severe psychopathology. Given the overall high impact of anxiety on patients' quality of life, clinicians should not underestimate the extent of different anxiety dimensions in PD.

White matter microstructure alterations correlate with terminally differentiated CD8+ effector T cell depletion in the peripheral blood in mania: Combined DTI and immunological investigation in the different phases of bipolar disorder. Brain Behav Immun 2018; 73:192-204.

Abstract
BACKGROUND White matter (WM) microstructural abnormalities and, independently, signs of immunological activation were consistently demonstrated in bipolar disorder (BD). However, the relationship between WM and immunological alterations as well as their occurrence in the various phases of BD remain unclear. METHOD In 60 type I BD patients - 20 in manic, 20 in depressive, 20 in euthymic phases - and 20 controls we investigated: (i) diffusion tensor imaging (DTI)-derived fractional anisotropy (FA), radial diffusivity (RD) and axial diffusivity (AD) using a tract-based spatial statistics (TBSS) approach; (ii) circulating T cell subpopulations frequencies, as well as plasma levels of different cytokines; (iii) potential relationships between WM and immunological data. RESULTS We found: (i) a significant widespread combined FA-RD alteration mainly in mania, with involvement of the body of corpus callosum (BCC) and superior corona radiata (SCR); (ii) significant increase in CD4+ T cells as well as significant decrease in CD8+ T cells and their subpopulations effector memory (CD8+ CD28-CD45RA-), terminal effector memory (CD8+ CD28-CD45RA+) and CD8+ IFNγ+ in mania; (iii) a significant relationship between WM and immunological alterations in the whole cohort, and a significant correlation of FA-RD abnormalities in the BCC and SCR with reduced frequencies of CD8+ terminal effector memory and CD8+ IFNγ+ T cells in mania only. CONCLUSIONS Our data show a combined occurrence of WM and immunological alterations in mania. WM abnormalities highly correlated with reduction in circulating CD8+ T cell subpopulations that are terminally differentiated effector cells prone to tissue migration, suggesting that these T cells could play a role in WM alteration in BD.

Abstract
UNLABELLED Evaluation of pain perception in chronic pain patients with a concomitant mood-spectrum disorder. DESIGN The observational retrospective study is based on patient data collected in psychosomatic consultations held at the Gift Institute for Integrative Medicine in Pisa, Italy, from 2002 to 2014. Evoked pain stimulus threshold and tolerance were evaluated using the cold pressor test. Clinical pain intensity and Sensorial, Affective, and Evaluative dimensions were assessed using the Italian Pain Questionnaire, and Anxiety and Depressive symptoms using the Hospital Anxiety Depression Scale. Mood-spectrum disorders were diagnosed via the Mini-International Neuropsychiatric Interview, and affective temperament in accordance with Akiskal and Pinto's criteria (1999). Of a total of 627 chronic pain clinic patients, 381 were diagnosed with a concomitant mood-spectrum (MS) disorder, unipolar (US) in 61.41%. Pain threshold (t = 2.28; p < 0.05) was lower, and all clinical pain dimensions (t = 2.28; p < 0.05) increased, in MS patients compared to those without psychiatric disorders. Pain intensity (F = 3.5, p < 0.05) and cognitive pain component scores (F = 7.84; p < 0.0001) were higher in US and, to a lesser extent Bipolar Spectrum, than in subjects with other (n.112) or no psychiatric disorders (n. 134). Suicide ideation was highest in US (F = 37.20; p < 0.0001), although in BS major depressive episodes had more melancholic features (F = 46.73; P < 0.0001), and a longer history of psychiatric disorders before the pain onset than US (F = 20.31; p < 0.0001). Pain management should take into account pre-existing psychiatric disorders.

Abstract
INTRODUCTION The objective of this study was to investigate affective temperaments of parents of children with ADHD and the relationship between ADHD and affective temperaments. METHODS The children diagnosed with ADHD were evaluated with a structured interview and the Turgay DSM-IV-Based Child and Adolescent Disruptive Behavioral Disorders Screening and Rating Scale (T-DSM-IV-S) was filled by parents. Then parents were evaluated by a structured clinical interview for DSM-IV (SCID-I), and those with no diagnosis of psychiatric disorder (in the past and at the time of the study) were included to the study. The Turkish version of the Temperament Evaluation of Memphis, Pisa, Paris and San Diego Auto-questionnaire was used to evaluate affective temperaments of parents. A control group of parents who has no children with ADHD was applied the same evaluation protocol. RESULTS The study was conducted with 123 parents (66 mothers, 57 fathers) of 66 children with ADHD and 119 control parents (65 mothers, 54 fathers) of 71 children without ADHD. Affective temperament scores of parents of children with ADHD were significantly higher than those of the control group. When the scores of mothers and fathers were compared separately, mothers had higher scores in all temperaments except hyperthymic temperament, and fathers had higher scores in all temperaments except anxious temperament in the ADHD group. Additionally, the T-DSM-IV-S attention deficit and hyperactivity/impulsivity scores of children were moderately correlated with most of the affective temperaments scores of their parents. CONCLUSION There is a relationship between ADHD and affective temperaments. Further studies are needed to understand the etiology, strength, and nature of this relationship.

Abstract
BACKGROUND Temperament and personality traits have been suggested as endophenotypes for bipolar disorder based on several lines of evidence, including heritability. Previous work suggested an anxious-reactive factor identified across temperament and personality inventories that produced significant group discrimination and could potentially be useful in genetic analyses. We have attempted to further characterize this factor structure in a sample of bipolar patients. METHODS A sample of 1195 subjects with bipolar I disorder was evaluated, all with complete data available. Dimension reduction across two inventories identified 18 factors explaining 39% of the variance. RESULTS The two largest factors reflected affective instability and general anxiety/worry, respectively. Subsequent analyses of the clinical features associated with bipolar disorder revealed specificity for the factors in a predictable pattern. Cluster analysis of the factors identified a subgroup defined by a strong lack of general anxiety and low affective instability represented by the first two factors. The remaining subjects could be distinguished into two clusters by the presence of either more positive characteristics, including persistence/drive, spirituality, expressivity, and humor, or more negative characteristics of depression and anxiety. LIMITATIONS These analyses involved bipolar I subjects only and must be extended to other bipolar spectrum diagnoses, unaffected relatives, and individuals at risk. CONCLUSIONS These results suggest that temperament and personality measures access latent traits associated with important clinical features of bipolar disorder. By translating clinical variables into quantitative traits, we may identify subgroups of bipolar patients with distinct clinical profiles, thereby facilitating both individual treatment strategies and genetic analyses.

Abstract
BACKGROUND The inclusion of subsyndromal forms of bipolarity in the fifth edition of the DSM has major implications for the way in which we approach the diagnosis of individuals with depressive symptoms. The aim of the present study was to use methods based on item response theory (IRT) to examine whether, when equating for levels of depression severity, there are differences in the likelihood of reporting DSM-IV symptoms of major depressive episode (MDE) between subjects with and without a lifetime history of manic symptoms. METHODS We conducted these analyses using a large, nationally representative sample from the USA (n=34,653), the second wave of the National Epidemiologic Survey on Alcohol and Related Conditions. RESULTS The items sadness, appetite disturbance and psychomotor symptoms were better indicators of depression severity in participants without a lifetime history of manic symptoms, in a clinically meaningful way. DSM-IV symptoms of MDE were substantially less informative in participants with a lifetime history of manic symptoms than in those without such history. LIMITATIONS Clinical information on DSM-IV depressive and manic symptoms was based on retrospective self-report CONCLUSIONS The clinical presentation of depressive symptoms may substantially differ in individuals with and without a lifetime history of manic symptoms. These findings alert to the possibility of atypical symptomatic presentations among individuals with co-occurring symptoms or disorders and highlight the importance of continued research into specific pathophysiology differentiating unipolar and bipolar depression.

Abstract
BACKGROUND This study intended to determine whether certain traits of temperament are associated with former and current ADHD symptomatology in a non-clinical sample of 18 year old males. METHODS We performed a cross sectional descriptive study of 3280 men during the examination for military service. The investigation included a socio-demographic questionnaire, screening for substance abuse, temperament (TEMPS-M), past (WURS) and current (ADHD symptom checklist) ADHD symptomatology. RESULTS We found a correlation of cyclothymic (p<.001), irritable (p<.001) and anxious (p<.05) temperament with occurrence and severity of past and present ADHD symptomatology. No significant correlation has been detected for hyperthymic and depressive temperament. Judged retrospectively, ADHD symptoms were strongly consistent over time. LIMITATIONS The sample consists of men only. These had to be fit enough to be enlisted for military service; men with severe mental or physical disorders were thus excluded. Furthermore, the cross-sectional study design does not allow making conclusions about the temporal relationships between ADHD symptoms and substance misuse. CONCLUSIONS These results indicate that a temperament based approach towards those affected by ADHD might be useful. Subtyping ADHD by integrating temperament profiles in diagnosis and treatment of the disorder could help explain some of the heterogeneity of the disease.

J Psychiatr Res 2016; 76:94-100. [PMID: 26921874 DOI: 10.1016/j.jpsychires.2016.02.006] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/13/2015] [Revised: 12/18/2015] [Accepted: 02/11/2016] [Indexed: 11/18/2022]
Abstract
BACKGROUND Suicide attempts are common in patients with bipolar disorder (BD), and consistently associated with female gender and certain unfavorable BD illness characteristics. Findings vary, however, regarding effects of BD illness subtype and yet other illness characteristics upon prior suicide attempt rates. We explored the effects of demographics and BD illness characteristics upon prior suicide attempt rates in patients stratified by BD illness subtype (i.e., with bipolar I disorder (BDI) versus bipolar II disorder (BDII)). METHODS Outpatients referred to the Stanford BD Clinic during 2000-2011 were assessed with the Systematic Treatment Enhancement Program for BD Affective Disorders Evaluation. Rates of prior suicide attempt were compared in patients with and without diverse demographic and BD illness characteristics stratified by BD subtype. RESULTS Among 494 BD outpatients (mean ± SD age 35.6 ± 13.1 years; 58.3% female; 48.6% BDI, 51.4% BDII), overall prior suicide attempt rates in were similar in BDI versus BDII patients, but approximately twice as high in BDI (but not BDII) patients with compared to without lifetime eating disorder, and in BDII (but not BDI) patients with compared to without childhood BD onset. In contrast, current threshold-level suicidal ideation and lifetime alcohol use disorder robustly but less asymmetrically increased prior suicide attempt risk across BD subtypes. LIMITATIONS American tertiary bipolar disorder clinic referral sample, cross-sectional design. CONCLUSIONS Further studies are needed to assess the extent to which varying clinical characteristics of samples of patients with BDI and BDII could yield varying prior suicide attempt rates in patients with BDI versus BDII.

Abstract
BACKGROUND Lithium is a first line treatment option in bipolar disorder, but several alternative treatments have been introduced in recent years, such as antiepileptic and atypical antipsychotic drugs. Little is known about how this has changed the prescription patterns. We investigated possible changes in the use of mood stabilizers and antidepressants in Sweden during 2007-2013. METHODS Data was collected from Swedish registers: the National Quality Assurance Register for bipolar disorder (BipoläR), the Prescribed Drug Register, and the Patient Register. Logistic regression models with drug use as outcomes were used to adjust for confounding factors such as sex, age, year of registration, and subtypes of bipolar disorder. RESULTS In both bipolar subtypes, lithium use decreased steadily during the study period, while the use of lamotrigine and quetiapine increased. The use of valproate decreased in bipolar II disorder and the use of olanzapine decreased among women. The use of antidepressant remained principally unchanged but increased somewhat in bipolar I disorder. LIMITATIONS We only report data from 2007 as the coverage of BipoläR prior to 2007 was too low to allow for reliable analyses. CONCLUSION Significant changes in the prescription of drugs in the treatment of bipolar disorder have occurred in recent years in Sweden. Further studies are needed to clarify whether these changes alter the outcome in bipolar disorder.

Contrasting variability patterns in the default mode and sensorimotor networks balance in bipolar depression and mania. Proc Natl Acad Sci U S A 2016; 113:4824-9.

Abstract
Depressive and manic phases in bipolar disorder show opposite constellations of affective, cognitive, and psychomotor symptoms. At a neural level, these may be related to topographical disbalance between large-scale networks, such as the default mode network (DMN) and sensorimotor network (SMN). We investigated topographical patterns of variability in the resting-state signal-measured by fractional SD (fSD) of the BOLD signal-of the DMN and SMN (and other networks) in two frequency bands (Slow5 and Slow4) with their ratio and clinical correlations in depressed (n = 20), manic (n = 20), euthymic (n = 20) patients, and healthy controls (n = 40). After controlling for global signal changes, the topographical balance between the DMN and SMN, specifically in the lowest frequency band, as calculated by the Slow5 fSD DMN/SMN ratio, was significantly increased in depression, whereas the same ratio was significantly decreased in mania. Additionally, Slow5 variability was increased in the DMN and decreased in the SMN in depressed patients, whereas the opposite topographical pattern was observed in mania. Finally, the Slow5 fSD DMN/SMN ratio correlated positively with clinical scores of depressive symptoms and negatively with those of mania. Results were replicated in a smaller independent bipolar disorder sample. We demonstrated topographical abnormalities in frequency-specific resting-state variability in the balance between DMN and SMN with opposing patterns in depression and mania. The Slow5 DMN/SMN ratio was tilted toward the DMN in depression but was shifted toward the SMN in mania. The Slow5 fSD DMN/SMN pattern could constitute a state-biomarker in diagnosis and therapy.

Comparative analysis of affective temperament in patients with difficult-to-treat and easy-to-treat major depression and bipolar disorder: Possible application in clinical settings. Compr Psychiatry 2016; 66:71-8. [PMID: 26995239 DOI: 10.1016/j.comppsych.2016.01.001] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/09/2015] [Revised: 12/18/2015] [Accepted: 01/08/2016] [Indexed: 12/28/2022] Open
Abstract
BACKGROUND Difficult-to-treat major depressive disorder (MDD-DT), which involves antidepressant refractoriness or antidepressant-related adverse psychiatric effects, is bipolar in nature; therefore, it may share common temperamental features with bipolar disorder. To examine this hypothesis, affective temperament was compared between MDD-DT, easy-to-treat major depressive disorder (MDD-ET), and bipolar disorder. METHODS Affective temperament was measured in 320 patients (69, 56, and 195 with MDD-ET, MDD-DT, and bipolar disorder, respectively) using the self-rated questionnaire version of the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego (TEMPS-A), with between-group differences examined using multiple logistic regression analysis controlling for confounders. Optimal cut-off points for TEMPS-A scores to discriminate between diagnostic groups were determined using receiver-operating characteristic analysis. RESULTS Of the five temperamental domains, the mode for cyclothymic temperament score was highest, followed by those of bipolar disorder, MDD-DT, and MDD-ET. The cyclothymic temperament score discriminated significantly between bipolar disorder and MDD-DT (odds ratio [OR]: 1.12, 95% confidence interval [CI]: 1.04-1.20, p=0.0022), MDD-DT and MDD-ET (OR: 1.15, 95% CI: 1.01-1.31, p=0.0334), and bipolar and major depressive disorders (OR: 1.17, 95% CI: 1.07-1.28, p=0.0003). Optimal cut-off points for the cyclothymic temperament scores to discriminate between bipolar disorder and major depressive disorder and MDD-DT and MDD-ET were 9 (sensitivity: 64.6%, specificity: 76.0%) and 6 (66.1%, 62.3%), respectively. CONCLUSIONS MDD-DT has a quantitatively stronger bipolar temperamental feature, cyclothymic temperament, relative to that of MDD-ET. Cut-off points determined in this study could be clinically helpful. Because of our study design, longitudinal changes in temperamental scores during treatment cannot be fully excluded.

Abstract
BACKGROUND In recent years, diffusion tensor imaging (DTI) studies have detected subtle microstructural abnormalities of white matter (WM) in type I bipolar disorder (BD). However, WM alterations in the different phases of BD remain to be explored. The aims of this study is to investigate the WM alterations in the various phases of illness and their correlations with clinical and neurocognitive features. METHODS We investigated the DTI-derived fractional anisotropy (FA), mean diffusivity (MD), radial diffusivity (RD) and axial diffusivity (AD) in patients with type I BD (n=61) subdivided in manic (n=21), depressive (n=20) and euthymic phases (n=20) vs. healthy controls (n=42), using a tract-based spatial statistics (TBSS) approach. Then, we investigated whether the subgroups of patients in the various phases of illness present different patterns of WM abnormalities. Finally we studied the correlations between WM alterations and clinical-cognitive parameters. RESULTS We found a widespread alteration in WM microstructure (decrease in FA and increase in MD and RD) in BD when compared to controls. The various subgroups of BD showed different spatial patterns of WM alterations. A gradient of increasing WM abnormalities from the euthymic (low degree and localized WM alterations mainly in the midline structures) to the manic (more diffuse WM alterations affecting both midline and lateral structures) and, finally, to the depressive phase (high degree and widespread WM alterations), was found. Furthermore, the WM diffuse alterations correlated with cognitive deficits in BD, such as decreased fluency prompted by letter and decreased hits and increased omission errors at the continuous performance test. LIMITATIONS Patients under treatment. CONCLUSIONS The WM alterations in type I BD showed different spatial patterns in the various phases of illness, mainly affecting the active phases, and correlated with some cognitive deficits. This suggests a complex trait- and state-dependent pathogenesis of WM abnormalities in BD.

Abstract
Bipolar disorder constitutes a challenge for clinicians in everyday clinical practice. Our knowledge concerning this clinical entity is incomplete, and contemporary classification systems are unable to reflect the complexity of this disorder. The concept of temperament, which was first described in antiquity, provides a helpful framework for synthesizing our knowledge on how the human body works and what determines human behavior. Although the concept of temperament originally included philosophical and sociocultural approaches, the biomedical model is dominant today. It is possible that specific temperaments might constitute vulnerability factors, determine the clinical picture, or modify the course of illness. Temperaments might even act as a bridge between genes and clinical manifestations, thus giving rise to the concept of the bipolar spectrum, with major implications for mental health research and treatment. More specifically, it has been reported that the hyperthymic and the depressive temperaments are related to the more "classic" bipolar disorder, whereas cyclothymic, anxious, and irritable temperaments are related to more complex manifestations and might predict poor response to treatment, violent or suicidal behavior, and high comorbidity. Incorporating of the concept of temperament and the bipolar spectrum into the standard training of psychiatric residents might well result in an improvement of everyday clinical practice.

Abstract
BACKGROUND Recent celebrity deaths have been widely reported in the media and turned the public attention to the coexistence of mood, psychiatric and substance-abuse disorders. These tragic and untimely deaths motivated us to examine the scientific and clinical data, including our own work in this area. The self-medication hypothesis states that individuals with psychiatric illness tend to use heroin to alleviate their symptoms. This study examined the correlations between heroin use, mood and psychiatric disorders, and their chronology in the context of dual diagnosis. METHODS Out of 506 dual diagnosed heroin addicts, 362 patients were implicated in heroin abuse with an onset of at least one year prior to the associated mental disorder (HER-PR), and 144 patients were diagnosed of mental illness at least one year prior to the associated onset of heroin use disorder (MI-PR). The retrospective cross-sectional analysis of the two groups compared their demographic, clinical and diagnostic characteristics at univariate and multivariate levels. RESULTS Dual diagnosis heroin addicts whose heroin dependences existed one year prior to their diagnoses (HER-PR) reported more frequent somatic comorbidity (p≤0.001), less major problems at work (p=0.003), more legal problems (p=0.004) and more failed treatment for their heroin dependence (p<0.001) in the past. More than 2/3 reached the third stage of heroin addiction (p=<0.001). Their length of dependence was longer (p=0.004). HER-PR patients were diagnosed more frequently as affected by mood disorders and less frequently as affected by psychosis (p=0.004). At the multivariate level, HER-PR patients were characterized by having reached stage 3 of heroin dependence (OR=2.45), diagnosis of mood disorder (OR=2.25), unsuccessful treatment (OR=2.07) and low education (OR=1.79). LIMITATIONS The main limitation is its retrospective nature. Nonetheless, it does shed light on what needs to be done from a clinical and public health perspective and especially prevention. CONCLUSIONS The data emerging from this study, does not allow us to determine a causal relation between heroin use and mental illness onset. However, this data, even if requiring longitudinal studies, suggest that self-medication theory, in these patients, can be applied only for chronic psychoses, but should not be applied to patients with mood disorders using heroin.

Abstract
AIMS To examine the prevalence of former heroin dependence (FHA) in Alcohol Use Disorder (AUD) patients; to compare the clinical characteristics of FHA-AUD patients versus AUD patients without any past use of heroin at alcohol treatment entry; to document the heroin dependence history of FHA-AUD patients, and review treatment strategies for this group. METHODS Retrospective case review of 448 consecutive AUD patients. RESULTS The annual entry of FHA-AUD showed stability over the study period of 3 years overall 60/448 (13.3%). FHA-AUD patients showed higher concomitant use of cocaine, benzodiazepines, cannabis and hallucinogens than other heroin addicts. They consumed higher amounts of alcohol at the beginning of their alcohol dependence history, and reached a high maximum level of alcohol consumption, than other AUD patients, and tended to have more physical disorders. The most important signals of FHA-AUD were polyabuse and older age at the time of presentation. FHA-AUD patients tended to have had a severe pattern of heroin dependence associated with inadequate agonist opiate treatment. CONCLUSIONS The prevalence of FHA-AUD patients is not negligible. This may relate to previous inadequate treatment of heroin addiction contributing to the development of severe AUD. For these patients we propose a reconsideration of 'soft' (low dose) agonist opiate treatment.

Abstract
BACKGROUND Patients with bipolar disorder (BD) suffer from greater physical morbidity and mortality than the general population. The aim of the present study is to explore the prevalence and clinical correlates of General Medical Conditions (GMC) in a large consecutive sample of patients with BD. METHOD The study sample comprised of 347 patients who met DSM-IV-TR criteria for BD I (n=207, 59.7%), BD II or Cyclothymic Disorder (n=140, 40.3). Diagnostic information was collected by means of the Structured Clinical Interview for DSM-IV Axis I Disorders- Clinical Version (SCID-I), and information about personal and family history were collected by the Semi-Structured Interview for Mood Disorder-Revised (SIMD-R). Standardized procedure was used to assess the diagnosis of GMC, which was considered present only if a specific therapy to treat the condition was prescribed by a specialist or a general practitioner. In order to explore possible relationships between physical comorbidity and clinical features of BD, we compared patients with (MD) and without (No-MD) Metabolic Diseases (MD) and patients with (AAD) and without (No-AAD) Autoimmune-Allergic Diseases (AAD). RESULTS The most commonly reported GMCs were: Headache, Hypercholesterolemia (>200mg/dl), Chronic Constipation, Obesity, Arterial Hypertension (BP >140/90 mmHg), Hypothyroidism, Allergic Rhino-Conjunctivitis, Irritable Bowel Syndrome, Hypertriglyceridemia (>150 mg/dl), Metabolic Syndrome, Hiatus Hernia, Dysmenorrhea, Urticaria, Atopic Dermatitis, Psoriasis, Seborrheic Dermatitis, Diabetes Mellitus, Bronchial Asthma, Cardiac Arrhythmias, Biliary Lithiasis, and COPD. In our sample, MD (n=148, 42.7%) and AAD (n=167, 48.1%) were the most common categories of GMCs. Interestingly, the lifetime prevalence of cancer and neoplastic diseases was very low: 1 patient (.3%) reported Lung Adenocarcinoma and 2 (.6%) patients Bowel Cancer. In the group comparisons, length of pharmacological treatment (OR=1.054; 95% CI=1.030-1.078), age at onset of first major episode (OR=1.043; 95% CI=1.019-1.067), length of the current episode (OR=1.025; 95% CI=1.020-1.533) and absence of lifetime comorbid substance abuse (OR=.373; 95% CI=.141-.989) were statistically associated with the presence of comorbid MD; while only AD-induced hypomania (OR=1.62; 95% CI=1.011-2.597), and cyclothymic temperament (OR=1.051; 95% CI=1.016-1.087) were statistically associated with the presence of comorbid AAD. LIMITATIONS Possible referral and selection bias; retrospective, non-blind, cross-sectional evaluation. CONCLUSION MD and AAD were highly represented in our sample, while cancer and neoplastic diseases were uncommon. The clinical correlates of different sub-groups of GMC suggest different interpretations. The presence of MD seems to be correlated with the progression of BD and the chronic medication exposure, while comorbid AAD seems to correlate with a specific clinical subtype of BD, characterized by mood reactivity and temperamental mood instability. If the link with autoimmune-allergic diathesis will be confirmed, it could provide an interesting new paradigm for the study of the "systemic" nature of mood disorders and a promising target for future treatment options.

In an effort to inquiry the "self-medication hypothesis" in heroin-dependent patients suffering from chronic psychosis and bipolar disorder, a naturalistic comparative cohort study was designed with the aim of comparing, according to the presence of dual diagnosis, the clinical characteristics of heroin-dependent patients presenting for their first agonist opioid treatment. The main finding was that addictive (heroin) illness was more severe in bipolar 1 patients and less severe in chronic psychotic patients when compared with heroin-dependent patients without dual diagnoses. In the case of chronic psychotic patients, these differences do not allow us to exclude a therapeutic heroin use, at least at the beginning of their toxicomanic career, with limited progression of their addictive disease. This occurrence seems to be excluded for bipolar 1 heroin-dependent patients, who come to their first agonist opioid treatment with a more severe addictive disease.

Functional connectivity and neuronal variability of resting state activity in bipolar disorder--reduction and decoupling in anterior cortical midline structures. Hum Brain Mapp 2014; 36:666-82. [PMID: 25307723 DOI: 10.1002/hbm.22655] [Citation(s) in RCA: 69] [Impact Index Per Article: 6.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2014] [Revised: 09/22/2014] [Accepted: 10/01/2014] [Indexed: 12/14/2022] Open
Abstract
INTRODUCTION The cortical midline structures seem to be involved in the modulation of different resting state networks, such as the default mode network (DMN) and salience network (SN). Alterations in these systems, in particular in the perigenual anterior cingulate cortex (PACC), seem to play a central role in bipolar disorder (BD). However, the exact role of the PACC, and its functional connections to other midline regions (within and outside DMN) still remains unclear in BD. METHODS We investigated functional connectivity (FC), standard deviation (SD, as a measure of neuronal variability) and their correlation in bipolar patients (n = 40) versus healthy controls (n = 40), in the PACC and in its connections in different frequency bands (standard: 0.01-0.10 Hz; Slow-5: 0.01-0.027 Hz; Slow-4: 0.027-0.073 Hz). Finally, we studied the correlations between FC alterations and clinical-neuropsychological parameters and we explored whether subgroups of patients in different phases of the illness present different patterns of FC abnormalities. RESULTS We found in BD decreased FC (especially in Slow-5) from the PACC to other regions located predominantly in the posterior DMN (such as the posterior cingulate cortex (PCC) and inferior temporal gyrus) and in the SN (such as the supragenual anterior cingulate cortex and ventrolateral prefrontal cortex). Second, we found in BD a decoupling between PACC-based FC and variability in the various target regions (without alteration in variability itself). Finally, in our subgroups explorative analysis, we found a decrease in FC between the PACC and supragenual ACC (in depressive phase) and between the PACC and PCC (in manic phase). CONCLUSIONS These findings suggest that in BD the communication, that is, information transfer, between the different cortical midline regions within the cingulate gyrus does not seem to work properly. This may result in dysbalance between different resting state networks like the DMN and SN. A deficit in the anterior DMN-SN connectivity could lead to an abnormal shifting toward the DMN, while a deficit in the anterior DMN-posterior DMN connectivity could lead to an abnormal shifting toward the SN, resulting in excessive focusing on internal contents and reduced transition from idea to action or in excessive focusing on external contents and increased transition from idea to action, respectively, which could represent central dimensions of depression and mania. If confirmed, they could represent diagnostic markers in BD.

Abstract
OBJECTIVE To examine attachment and affective temperament in patients who have been diagnosed with Bipolar Disorder and to investigate possible differences in both variables among Bipolar I Disorder (BD-I), Bipolar II Disorder (BD-II), and cyclothymic patients. METHODS Ninety (45 male and 45 female) outpatients with bipolar or cyclothymic disorder between the ages of 18 and 65years were recruited consecutively between September 2010 and December 2011 at the Bipolar Disorder Unit of the Psychiatry Day Hospital affiliated with the University General Hospital "A. Gemelli" in Rome, Italy. Patients were assessed using the Structured Clinical Interview for DSM-IV, the Hamilton Depression Rating Scale, the Young Mania Rating Scale, the Temperament Evaluation of Memphis, Pisa, and San Diego-auto-questionnaire version, and the Experiences in Close Relationships (ECR) questionnaire applied by trained interviewers. RESULTS The 3 groups of patients differed only on the ECR Anxiety scores with BD-I patients having the highest anxiety levels, followed by the BD-II patients, and the patients with cyclothymic disorder reporting the lowest level of anxiety. CONCLUSIONS This finding suggests that bipolar disorder (type I, type II) and cyclothymic/dysthymic temperament are more strongly associated with insecure attachment style as compared to the general population.

Abstract
BACKGROUND The many attempts to identify genes for bipolar disorder (BD) have met with limited success, which has generally been attributed to genetic heterogeneity and small gene effects. However, it is also possible that the categorical phenotypes used in genetic studies of BD are not the most informative or biologically relevant. We have explored aspects of temperament as quantitative phenotypes for BD through the use of the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego Auto-questionnaire (TEMPS-A), which is designed to assess lifelong, milder aspects of bipolar symptomatology and defines five temperaments: hyperthymic, dysthymic, cyclothymic, irritable, and anxious. METHODS We compared temperament scores between diagnostic groups and assessed heritability in a sample of 101 families collected for genetic studies of BD. A genome-wide SNP linkage study was then performed in the subset of 51 families for which genetic data was available. RESULTS Significant group differences were observed between BD subjects, their first-degree relatives, and independent controls, and all five temperaments were found to be significantly heritable, with heritabilities ranging from 21% for the hyperthymic to 52% for the irritable temperaments. Suggestive evidence for linkage was observed for the hyperthymic (chromosomes 1q44, 2p16, 6q16, and 14q23), dysthymic (chromosomes 3p21 and 13q34), and irritable (chromosome 6q24) temperaments. LIMITATIONS The relatively small size of our linkage sample likely limited our ability to reach genome-wide significance in this study. CONCLUSIONS While not genome-wide significant, these results suggest that aspects of temperament may prove useful in the identification of genes underlying BD susceptibility.

Abstract
The aims of the study were: (1) to study possible associations between temperament, personality dimensions, and psychopathological variables in a clinical sample of euthymic patients with bipolar disorder (BD) and cyclothymia; and (2) to assess how Cloninger's temperament and personality dimensions were associated with affective temperaments. Participants, consisting of 60 patients with BD (type I or II) and cyclothymia in the euthymic phase, completed Akiskal's Temperament Evaluation of Memphis, Pisa, Paris, and San Diego-Autoquestionnaire (TEMPS-A), and Cloninger's Temperament and Character Inventory-revised version (TCI-R). The diagnostic groups differed in past hospitalization, for age at onset of the disorder, and on two affective temperaments: the TEMPS-A Hyperthymia, and the TEMPS-A Irritability. There were six significant associations between affective temperaments and Cloninger's personality dimensions, ranging from 0.26 to 0.54. The measures of Akiskal and of Cloninger tap common behavioral features in patients with bipolar disorder and cyclothymia, yet the differences indicate that the two measures are not redundant. BD and cyclothymic patients differed significantly in temperament and personality, differences that may have important implications for treatment.

Abstract
OBJECTIVE To date, the affective temperamental characteristics of adults with attention-deficit hyperactivity disorder (ADHD) have not been studied. The aim of this study is to explore those temperamental characteristics for adults diagnosed with ADHD as measured by the TEMPS-A and then to compare those results with results for individuals diagnosed with bipolar disorder (BD) and with healthy controls. METHODS Forty adults with ADHD, 40 patients with BD, and 40 healthy controls were enrolled in this study. The groups were matched by age and gender. All patients were assessed using the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID I), the Hamilton Depression Rating Scale, the Hamilton Anxiety Rating Scale, the Young Mania Rating Scale and the Wender Utah Rating Scale. Subjects' temperamental characteristics were examined using the Turkish version of the Temperament Evaluation of Memphis, Pisa, Paris and San Diego-auto questionnaire (TEMPS-A). RESULTS Ten subjects (25%) in the ADHD group and 15 subjects (30%) in the bipolar group had at least one dominant temperament. There was no identifiable dominant temperament in the control group. Compared to the control group, the ADHD group scored higher than other groups on all domains of the TEMPS-A: depressive cyclothymic, irritable and anxious. However, the hyperthymic domain was not higher for this group. Adults with ADHD scored higher on the irritable temperament scale as compared to the BD group. The ADHD and BD groups had similar mean scores for each of the other four temperaments. CONCLUSION The adults diagnosed with ADHD in this study had different temperamental characteristics from the control group, and these temperamental characteristics were similar to those of the bipolar patients. Recognizing the role of temperamental characteristics in adults with ADHD may increase our understanding of ADHD.

Psychometric properties of the Chinese (Mandarin) TEMPS-A: a population study of 985 non-clinical subjects in China. J Affect Disord 2013; 147:29-33.

Abstract
BACKGROUND The TEMPS-A (Temperament Evaluation of Memphis, Pisa, Paris and San Diego) is a 110-item auto-questionnaire (self-rated) which consists of five temperament scales: depressive, cyclothymic, hyperthymic, irritable and anxious temperaments. It has been translated into over 25 languages and validated in at least 12, with broad cross-cultural cogency. This is a first attempt to validate the TEMPS-A in a very large Chinese population speaking Mandarin. METHODS The Chinese TEMPS-A was adapted from the original English version following a rigorous process of forward translation and backward translation (after the approval of the English back translation by H.S.A. and K.K.A.), it was administered to 985 non-clinical Chinese subjects aged between 18-60 years (53.8% female) in four communities in Guangzhou City, China. A subset of 105 subjects was retested approximately six weeks later. Standard psychometric tests of reliability and validation were performed. RESULTS The test-retest reliability for depressive (0.74), cyclothymic (0.71), hyperthymic (0.67), irritable (0.66) and anxious (0.83) were respectively as shown in the parentheses. For internal consistency, Chronbach alphas coefficients were 0.68, 0.85, 0.82, 0.83 and 0.87, respectively. Exploratory factor analysis revealed 2 super factors, Factor I loading on anxious, cyclothymic, irritable, and depressive temperaments; and Factor II loading on hyperthymic. Depressive, cyclothymic, irritable and anxious temperaments were correlated with each other. Males had significantly higher scores than females for the hyperthymic and irritable temperaments. The prevalence of the dominant depressive (2.9%), cyclothymic (5.6%), hyperthymic (1.3%), irritable (7.0%) and anxious (5.3%) temperaments were respectively as shown in the parentheses. LIMITATIONS Although it is likely that generalizability of our scale is good for the entire Mandarin-speaking ethnic composition of China today, future research is needed to establish this conclusively. CONCLUSION The Chinese TEMPS-A standardized on one of the largest non-clinical samples in any of the other national studies to date, has good internal consistency, coheres well with validated versions in other languages. The findings suggest that it is a psychometrically sound instrument to assess affective temperaments in clinical and biological studies in China.

Abstract
BACKGROUND The many attempts to identify genes for bipolar disorder (BD) have met with limited success, which has generally been attributed to genetic heterogeneity and small gene effects. However, it is also possible that the categorical phenotypes used in genetic studies of BD are not the most informative or biologically relevant. Although quantitative phenotypes provide an alternative to categorical phenotypes based on diagnosis, they have not been fully exploited in BD genetics due to the lack of accessible biological measures. We have explored aspects of temperament as quantitative phenotypes that might define subtypes of BD with different clinical features and courses of illness. Temperament is a heritable personality factor that establishes the baseline level of reactivity, mood, and energy of a person. METHODS We have performed a genome-wide association study with genotype data from the Bipolar Genome Study and 1263 bipolar subjects that had completed the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego Autoquestionnaire (TEMPS-A). The TEMPS-A is designed to assess lifelong, milder aspects of bipolar symptomatology and defines five temperaments: hyperthymic, dysthymic, cyclothymic, irritable, and anxious. RESULTS The irritable temperament produced the most significant result with a genome-wide significant p value of 1.7 × 10(-8) on chromosome 1. The hyperthymic temperament produced additional genome-wide significant p values of 4.1 × 10(-8) and 2.1 × 10(-8) on chromosomes 12 and 22, respectively. CONCLUSIONS These results suggest that aspects of temperament might define subtypes of BD that are more clinically and genetically homogenous, which might aid in the identification of predisposing genetic variants.

Abstract
In a group of 1066 heroin addicts, who were seeking treatment for opioid agonist treatment, we looked for differences in historical, demographic, and clinical characteristics, between patients with different levels of awareness of illness (insight). The results showed that, in the cohort studied, a majority of subjects lacked insight into their heroin-use behavior. Compared with the impaired-insight group, those who possessed insight into their illness showed significantly greater awareness of past social, somatic, and psychopathological impairments, and had a greater number of past treatment-seeking events for heroin addiction. In contrast with other psychiatric illnesses, the presence of awareness appears to be related to the passing of time and to the worsening of the illness. Methodologies to improve the insight of patients should, therefore, be targeted more directly on patients early in their history of heroin dependence, because the risk of lack of insight is greatest during this period.

Abstract
Recent literature demonstrates the relationship between psychopathology and medically unexplained pain, even if the results of several studies show a high degree of variability. The present study was planned with the aim of analysing both the possible relationship between the level (low/high) of organicity and the presence of psychopathology, and the degree to which these differences are related to methodological problems. Between 1998 and 2000, four hundred and thirty six consecutive patients seen at the Pisa Pain Therapy and Palliative Care Unit were requested to fill in a questionnaire, the GHQ-12, to screen the subjects probably with (GHQ-12>3) or without (GHQ-12</=3) psychopathology. All the patients scoring above the GHQ-12 threshold (score of 3), and a randomised sample of those scoring below the GHQ-12 threshold, were included in the study. These patients were then interviewed using three different instruments: the Mini International Neuropsychiatric Interview (MINI) for a standardised psychiatric diagnosis, the Semistructured Interview for Depression (SID) for the characterisation of temperament, and the Italian Pain Questionnaire (IPQ) for the evaluation of pain. Our results suggest that Somatisation Disorders are more frequent in the medically unexplained pain group than in the medically explained pain group, whereas the other psychiatric disorders have a similar prevalence in the two pain groups. Mood and anxiety disorders are correlated with high scores on GHQ-12 and medically explained pain has a higher prevalence of GHQ-12>3 than the medically unexplained pain group. These results confirm that methodology is an important factor that could modify results in psychiatric research. Both medically unexplained pain and the presence of psychopathology are significantly correlated with sex, and age: females and young patients have a higher prevalence of psychopathology and of medically unexplained pain. Our results suggest that in the correlation between the low organicity of pain and psychopathology, the age and sex play a relevant role.

Abstract
UNLABELLED Affective temperament and psychopathological traits such as separation anxiety (SA) and interpersonal sensitivity (IPS) are supposed to impact on the clinical manifestation and on the course of Bipolar Disorder (BD); in the present study we investigated their influence on the definition of BD subtypes. METHOD : Among 106 BD-I patients with DSM-IV depressive, manic or mixed episode included in a multi-centric Italian study and treated according to the routine clinical practice, 89 (84.0%) were in remission after a follow-up period ranging from 3 to 6 months (Clinical Global Impression-BP [CGI-BP] <2). Remitting patients underwent a comprehensive evaluation including self-report questionnaires such as the Temperament Evaluation of Memphis, Pisa, Paris and San Diego (TEMPS-A) scale, Separation Anxiety Symptom Inventory (SASI), Interpersonal Sensitivity Measure (IPSM) and the Semi-structured interview for Mood Disorder (SIMD-R) administered by experienced clinicians. Correlation and factorial analyses were conducted on temperamental and psychopathological measures. Comparative analyses were conducted on different temperamental subtypes based on the TEMPS-A, SASI and IPSM profile. RESULTS : Depressive, cyclothymic and irritable TEMPS-A score and SASI and IPSM total scores were positively and statistically correlated with each other. On the contrary, hyperthymic temperament score was negatively correlated with depressive temperament and not significantly correlated with the other temperamental and psychopathological dimensions. The factorial analysis of the TEMPS-A subscales and SASI and IPSM total scores allowed the extraction of 2 factors: the cyclothymic-sensitive (explaining 46% of the variance) that included, as positive components, depressive, cyclothymic, irritable temperaments and SASI and IPSM scores; the hyperthymic (explaining the 19% of the variance) included hyperthymic temperament as the only positive component and depressive temperament and IPSM, as negative components. Dominant cyclothymic-sensitive patients (n=49) were more frequently females and reported higher number of depressive, hypomanic and suicide attempts when compared to the dominant hyperthymic patients (n=40). On the contrary, these latter showed a higher number of manic episodes and hospitalizations than cyclothymic-sensitive patients. The rates of first-degree family history for both mood and anxiety disorders were higher in cyclothymic-sensitive than in hyperthymic patients. Cyclothymic sensitive patients also reported more axis I lifetime co-morbidities with Panic Disorder/Agoraphobia and Social Anxiety Disorder in comparison with hyperthymics. As concerns axis II co-morbidity the cyclothymic-sensitive patients met more frequently DSM-IV criteria 1, 5 and 7 for borderline personality disorder than the hyperthymics. On the contrary, antisocial personality disorder was more represented among hyperthymic than cyclothymic patients, in particular for DSM-IV criteria 1 and 6. LIMITATION : No blind evaluation and uncertain validity of personality inventory. CONCLUSION : Our results support the view that affective temperaments influence the clinical features of BD in terms of both clinical and course characteristics, family history and axis I and II co-morbidities. Hypothetical temperamental subtypes as measured by TEMPS-A presented important interrelationships that permit to reliably isolate two fundamental temperamental disposition: the first characterized by rapid fluctuations of mood and emotional instability, and the second by hyperactivity, high level of energy and emotional intensity. Dominant cyclothymic and hyperthymic bipolar I patients reported important differences in terms of gender distribution, number and polarity of previous episodes, hospitalizations, suicidality, rates of co-morbid anxiety and personality traits and disorders. Our data are consistent with the hypothesis that affective temperaments, and in particular cyclothymia, could be utilized as quantitative, intermediate phenotypes in order to identify BD susceptibility genes.

Woodruff E, Genaro LT, Landeira-Fernandez J, Cheniaux E, Laks J, Jean-Louis G, Nardi AE, Versiani MC, Akiskal HS, Mendlowicz MV. Validation of the Brazilian brief version of the temperament auto-questionnaire TEMPS-A: the brief TEMPS-Rio de Janeiro. J Affect Disord 2011; 134:65-76. [PMID: 21782248 DOI: 10.1016/j.jad.2011.02.005] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/07/2010] [Revised: 01/19/2011] [Accepted: 02/01/2011] [Indexed: 11/26/2022]
Abstract
BACKGROUND Over the last thirty years, Akiskal and collaborators have described and developed operationalized diagnostic criteria for five types of affective temperaments - cyclothymic, irritable, hyperthymic, depressive, and anxious. A 110-item, yes-or-no questionnaire, the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego (TEMPS-A), was specifically developed for measuring temperamental variation. The TEMPS-A was translated into more than 25 languages and cross-culturally valid versions are now available in Italian, French, German, Japanese, Turkish, Arabic, Polish, Hungarian, Spanish and Portuguese. Recent studies in the US and in Europe, however, have suggested that shorter versions of TEMPS-A can be just as efficient as the full ones while potentially enhancing the compliance of respondents. The main objective of the present study was to validate a brief Brazilian Portuguese version of TEMPS-A (brief TEMPS-Rio de Janeiro). METHODS Our main sample consisted of 997 undergraduate students (female = 72.6%) from seven different universities located in the city of Rio de Janeiro, Brazil. An additional group of 167 healthy senior citizens (women = 83.8%) was recruited in senior community centers in the city of Rio de Janeiro, Brazil. All participants were asked to complete the 110-item, Brazilian translation of the full version of the TEMPS-A. RESULTS An exploratory factor analysis (PCA type 2, Varimax rotation) vying for a five-factor solution yielded mixed results, with cyclothymic traits, physical symptoms of anxiety and preoccupation with the well-being of a family member loading together on the first factor. When a forced six-factor solution was attempted, cyclothymic, irritable, hyperthymic, and depressive were delineated as predicted by the theory. The original generalized anxious temperament was split into two sharply delimited components, a "worrying" subscale and an abbreviated anxious subscale, which included physical symptoms of anxiety and concerns with the well-being of relatives. Based on the tripartite model of anxiety and depression, we proposed that the abridged anxious subscale, which includes physical symptoms of anxiety, represents the "true" generalized anxious temperament, while the "worrying" subscale corresponds to the "general distress factor". The internal consistency of the six subscales thus identified was generally good, ranging from 0.67 (anxious subscale) to 0.81 (worrying subscale), with cyclothymic, irritable, depressive, and hyperthymic subscales exhibiting intermediate values (0.74, 0.74, 0.72, and 0.7, respectively). LIMITATIONS The present study was based on a non-clinical sample that does not reflect accurately the characteristics of the Brazilian population. The relative uniformity of the sample in terms of age and education precluded a more in-depth analysis of the influence of these highly relevant factors. Further, we did not assess convergent, divergent or test-retest validity. CONCLUSIONS We believe that the brief Brazilian version of the TEMPS-A auto-questionnaire will provide Brazilian researchers and clinicians with a psychometrically sound instrument and thus contribute toward the creation of a worldwide research network dedicated to the investigation of affective temperaments.

Abstract
The constructs of atypical depression, bipolar II disorder and borderline personality disorder (BPD) overlap. We explored the relationships between these constructs and their temperamental underpinnings. We examined 107 consecutive patients who met DSM-IV criteria for major depressive episode with atypical features. Those who also met the DSM-IV criteria for BPD (BPD+), compared with those who did not (BPD-), had a significantly higher lifetime comorbidity for body dysmorphic disorder, bulimia nervosa, narcissistic, dependent and avoidant personality disorders, and cyclothymia. BPD+ also scored higher on the Atypical Depression Diagnostic Scale items of mood reactivity, interpersonal sensitivity, functional impairment, avoidance of relationships, other rejection avoidance, and on the Hopkins Symptoms Check List obsessive-compulsive, interpersonal sensitivity, anxiety, anger-hostility, paranoid ideation and psychoticism factors. Logistic regression revealed that cyclothymic temperament accounted for much of the relationship between atypical depression and BPD, predicting 6 of 9 of the defining DSM-IV attributes of the latter. Trait mood lability (among BPD patients) and interpersonal sensitivity (among atypical depressive patients) appear to be related as part of an underlying cyclothymic temperamental matrix.

Abstract
Although twin, family, and adoption studies demonstrate that bipolar disorder (BPD) is substantially heritable, the molecular genetic basis for this illness remains elusive. Given evidence that genes predisposing to BPD may be transmitted without expression of the clinical phenotype, interest has arisen in developing endophenotypes - indicators of processes mediating between genotype and phenotype. Patients with BPD have subtle neuropsychological abnormalities, even during periods of symptom remission. Some of these neurocognitive deficits are present in unaffected family members of probands with BPD, suggesting that these measures may be quantitative endophenotypes for the disorder. Similarly, BPD is associated with specific personality traits (e.g., reduced inhibition, increased risk-taking) that have been observed in both affected individuals and their family members. In this chapter, we review the evidence for candidate neurocognitive and personality endophenotypes for BPD. We conclude that neurocognitive and personality traits appear to be appropriate endophenotypes for BPD, suggesting that these measures share some genetic factors with the illness.

Abstract
OBJECTIVE The prevalence of suicide attempts (SA) in bipolar II disorder (BPII), particularly in comparison to the prevalence in bipolar I disorder (BPI), is an understudied and controversial issue with mixed results. To date, there has been no comprehensive review of the published prevalence data for attempted suicide in BPII. METHODS We conducted a literature review and meta-analysis of published reports that specified the proportion of individuals with BPII in their presentation of SA data. Systematic searching yielded 24 reports providing rates of SA in BPII and 21 reports including rates of SA in both BPI and BPII. We estimated the prevalence of SA in BPII by combining data across reports of similar designs. To compare rates of SA in BPII and BPI, we calculated a pooled odds ratio (OR) and 95% confidence interval (CI) with random-effect meta-analytic techniques with retrospective data from 15 reports that detailed rates of SA in both BPI and BPII. RESULTS Among the 24 reports with any BPII data, 32.4% (356/1099) of individuals retrospectively reported a lifetime history of SA, 19.8% (93/469) prospectively reported attempted suicide, and 20.5% (55/268) of index attempters were diagnosed with BPII. In 15 retrospective studies suitable for meta-analysis, the prevalence of attempted suicide in BPII and BPI was not significantly different: 32.4% and 36.3%, respectively (OR = 1.21, 95% CI: 0.98-1.48, p = 0.07). CONCLUSION The contribution of BPII to suicidal behavior is considerable. Our findings suggest that there is no significant effect of bipolar subtype on rate of SA. Our findings are particularly alarming in concert with other evidence, including (i) the well-documented predictive role of SA for completed suicide and (ii) the evidence suggesting that individuals with BPII use significantly more violent and lethal methods than do individuals with BPI. To reduce suicide-related morbidity and mortality, routine clinical care for BPII must include ongoing risk assessment and interventions targeted at risk factors.

Abstract
The short (s) variant of the serotonin transporter gene linked functional polymorphic region (5-HTTLPR) is associated with depression. Stressful life events, gender, and race have been shown to moderate this association. Because features of mania/hypomania seem to constitute an indicator of higher severity of depression, we examined the relationship between 5-HTTLPR genotype and symptoms of mania-hypomania spectrum occurring over the lifetime in patients with major depression. The possible moderating role of gender in this relationship was taken into account. Two hundred twenty-two patients with unipolar major depression were genotyped for 5-HTTLPR and nine other representative polymorphisms, and were administered the Mood Spectrum Questionnaire, Lifetime Version (MOODS-SR). The manic-hypomanic (MH) component score was used for analysis. Using a linear model of the MH score as a function of genotypes and gender, controlling for age, severity of depression, and site, we found significant effects of gender (F = 8.003, df = 1, P = 0.005), of the interaction gender x genotype (F = 4.505, df = 2, P = 0.012), and of the baseline Hamilton score (F = 5.404, df = 1, P = 0.021), non-significant effects of genotype (F = 1.298, df = 2, P = 0.275), age (F = 0.310, df = 1, P = 0.578) site (F = 0.504, df = 1, P = 0.479). Significant associations were also detected at three other SNPs. The association between the manic/hypomanic component of the MOODS-SR and the polymorphisms of the 5-HTTLPR is moderated by gender. This finding is intriguing from a clinical point of view because women with unipolar disorder and the "ss" genotype seem to constitute a sub-group with higher severity of depression. These results should be considered tentative pending replication in other samples.

Abstract
BACKGROUND While previous attempts to elucidate the factor structure of depression tended to agree on a central focus on depressed mood, other factors were not replicated across studies. By examining data from a large number of items covering the range of depressive symptoms, the aim of the present study is to contribute to the identification of the structure of depression on a lifetime perspective. METHODS The study sample consisted of 598 patients with unipolar depression who were administered the Mood Spectrum Self-Report (lifetime version) in Italian (N=415) or English (N=183). In addition to classical exploratory factor analysis using tetrachoric correlation coefficients, an IRT-based factor analysis approach was adopted to analyze the data on 74 items of the instrument that explore cognitive, mood and energy/activity features associated with depression. RESULTS Six factors were identified, including 'Depressive Mood', 'Psychomotor Retardation', 'Suicidality', 'Drug/Illness related depression', 'Psychotic Features' and 'Neurovegetative Symptoms', accounting overall for 48.3% of the variance of items. LIMITATIONS Clinical information on onset of depression and duration of illness is available only for 350 subjects. Therefore, differences between sites can only be partially accounted using available data. CONCLUSIONS Our study confirms the central role of depressed mood, psychomotor retardation and suicidality and identifies the factors 'Drug/Illness related depression', 'Psychotic features' and the neurovegetative dysregulation not captured by the instruments most frequently used in previous studies. The identification of patients with specific profiles on multiple factors may be useful in achieving greater precision in neuroimaging studies and in informing treatment selection.

Abstract
OBJECTIVES Although major depression is characteristic of both bipolar disorder and major depressive disorder, there is disagreement as to whether there are distinct features of depression that differentiate these two conditions. The primary aim of this study was to use methods based in item response theory to evaluate differences in DSM-IV depression symptom endorsement in an epidemiological sample of individuals with a history of mania (i.e., bipolar depression) versus those without (i.e., unipolar depression). METHODS Clinical interview data were drawn from a subsample (n = 13,058) of individuals with bipolar or unipolar depression who had participated in the National Epidemiologic Survey on Alcohol and Related Conditions. Using these data, a two-parameter item response model was used to estimate differential item functioning of DSM-IV depressive symptoms between these two groups. RESULTS Differences in severity parameter estimates revealed that suicidal ideation and psychomotor disturbance were more likely to be endorsed across most levels of depression severity in bipolar versus unipolar depression. Differences in discrimination parameter estimates revealed that fatigue was significantly less discriminating in bipolar versus unipolar depression. CONCLUSIONS Equating for level of depression symptom severity, study results revealed that suicidal ideation and psychomotor disturbance are endorsed more frequently in bipolar versus unipolar depression. Study data also suggested that fatigue may be endorsed more frequently in unipolar relative to bipolar samples at moderate (versus low or high) levels of depression symptom severity.

Abstract
OBJECTIVE The aim of this study was to estimate the incidence of treatment-emergent mania/hypomania (TEMH) and to describe the clinical characteristics of patients with major depression experiencing this event during treatment with a selective serotonin reuptake inhibitor (SSRI) and/or interpersonal psychotherapy (IPT). METHODS Following an algorithm-based protocol, 344 patients with major depression confirmed with the Structured Clinical Interview for DSM-IV disorders were treated with an SSRI, interpersonal psychotherapy, or their combination for nine months. The emergence of mania/hypomania was carefully monitored throughout the study using the Young Mania Rating Scale and clinical assessment. RESULTS Overall, eight patients experienced TEMH. The incidence of this event was 3.0% in patients treated with an SSRI and 0.9% in patients treated with IPT alone. Among patients treated with an SSRI, the difference between sites was higher than expected by chance alone (6.8% at Pisa and 0% at Pittsburgh, p = 0.002). Despite the adoption of an identical protocol at the two sites, some demographic and clinical characteristics of participants may account for this unexpected result. Alternatively, the greater number of episodes and earlier age of onset at the Pittsburgh site suggests that the unipolar course of illness was more clearly established prior to study entry. CONCLUSIONS TEMH is an infrequent event, occurring in 2.3% of patients treated for major depression. Nevertheless, its consequences are clinically relevant and require prompt and appropriate therapeutic interventions. For this reason, recognising those patients at risk for such an event is of paramount clinical significance. The observed difference in the incidence of TEMH between the two sites requires further investigation.

Abstract
BACKGROUND Our aim was to study the psychometrics and factor structure replicability of the Temperament Evaluation of Memphis, Pisa, Paris and San Diego Autoquestionnaire (TEMPS-A) in its Italian (Rome) Version. The questionnaire is a self-report 110-item measure that postulates five affective temperaments-the depressive, cyclothymic, irritable, hyperthymic, and anxious-which embody both strengths and liabilities along affective reactivity. In Italian, the TEMPS has previously been validated in its original 32-item version, the TEMPS-I (Pisa), one which did not yet include an anxious subscale. METHODS The present sample consisted of 948 nonclinical subjects (27.39 years+/-8.22 S.D.). There were 476 men (50.2%: 28.56 years+/-8.63 S.D.) and 472 women (49.8%: 26.21 years+/-7.61 S.D.). Reliability and validity were assessed by standard psychometric tests. RESULTS Principal Components Analysis with Varimax rotation resulted in a 3-factor solution: the first with highest explained variance (8.84%) represents Dysthymic, Cyclothymic and Anxious (Dys-Cyc-Anx) temperaments combined; the second identifies Irritable temperament (5.65% of variance); and the third Hyperthymic temperament (5.16% of variance). Cronbach Alpha coefficients for the three subscales were respectively .89, .77 and .74. The rates for the Dys-Cyc-Anx were 2.7%, and for the Irritable 3.1%. Despite the low rate of the Hyperthymic temperament (.2%), nonetheless 16% were between 1st and 2nd SD. Exploratory factor analysis revealed a positive loading combining Dys-Cyc-Anx with the Irritable; the Hyperthymic loaded negatively on this factor. In terms of dominant temperaments, based on z-scores, 2.7% were dysthymic, 1.7% cyclothymic, .7% hyperthymic, 3.5% irritable and 3% anxious. LIMITATION Although developed for self-rated use, the Italian authors nonetheless administered the TEMPS-A in an interview format. It is uncertain in what ways this procedure could have influenced our results, if any. Another limitation is that we did not assess test-retest reliability. CONCLUSIONS These data identify at least 3-factors, Dys-Cyc-Anx and Irritable (which are correlated), and Hyperthymic, which is uncorrelated with the others. Though our data are reminiscent of the neuroticism-extraversion distinction, importantly traits are operationalized in affective terms. Beyond the well-known relationship between the Dysthymic and Cyclothymic subscales and that between the Dysthymic and Anxious, the present data reveal a strong relationship between the Cyclothymic and Anxious as well, which is of great relevance for bipolar II. It is also provocative that much of hyperthymia (16%) in the +SD is between the 1st and 2nd SD, thereby "normalizing" this temperament in Italy, as previously reported by TEMPS-I (Pisa) from Northern Italy (and TEMPS-A from Lebanon and Argentina).

Abstract
The results of the thyrotropin-releasing hormone (TRH) stimulation test and the combined dexamethasone/corticotropin-releasing hormone (DEX/CRH) test are believed to correlate with social support status in patients with major depressive disorder. We studied 41 consecutive patients hospitalized for major depressive disorder and tested their responses to DEX/CRH and TRH on hospital days 4-7. DeltaMAX TSH and DeltaMAX cortisol were measured. Multiple regression analysis found that social support questionnaire (SSQ-A) and SSQ-B scores were significantly related to DeltaMAX cortisol and DeltaMAX TSH, respectively, at the time of admission. Social support might contribute partially to the TRH and DEX/CRH test results in patients with major depressive disorder.

Abstract
OBJECTIVE As a commitment to the International Society for Bipolar Disorders (ISBD), a Task Force was developed to investigate the diagnostic value of bipolar II disorder. METHODS Task Force members worked jointly reviewing all relevant literature (original articles, reviews, letters, book chapters and congress presentations) that included 'bipolar II disorder' and/or 'hypomania' as key words. RESULTS Bipolar II disorder appears to be a reasonably valid and reliable diagnostic category yet often underdiagnosed or misdiagnosed as unipolar disorder or personality disorder. Moreover, it is officially recognized as a mental disorder in DSM-IV-TR but not in ICD-10, and many clinicians still regard it as a milder form of manic-depressive illness, despite data supporting high morbidity and mortality rates. In fact, bipolar II may be the most prevalent bipolar phenotype, although current diagnostic boundaries are seen as quite restrictive concerning the required duration for hypomania (4 days), the exclusion of hypomanic episodes potentially triggered by antidepressants and other substances, and the negligence of hypomanic mixed states. The course of bipolar II disorder is characterized by depressive predominant polarity, and its treatment is still controversial and poorly evidence-based. CONCLUSIONS Bipolar II disorder is supported as a distinct category within mood disorders, but the definition and boundaries deserve a greater clarification in the DSM-V and ICD-11.

J Affect Disord 2008; 106:55-61. [PMID: 17669508 DOI: 10.1016/j.jad.2007.03.015] [Citation(s) in RCA: 26] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/17/2006] [Accepted: 03/05/2007] [Indexed: 11/22/2022]
Abstract
BACKGROUND Several studies indicate a specific relationship between bipolar disorder and stimulant use and abuse. It has generally been assumed that cocaine use represents self-enhancement or attempts to optimize one's level of hypomania, cyclothymia or hyperthymia. This topic required further examination among heroin abusers because cocaine abuse is commonly comorbid with heroin abuse. METHODS Cocaine abuse by bipolar subjects was investigated in a group of 1090 treatment-seeking heroin addicts enrolled between 1994 and 2005. We collected data with 1) the Drug Addiction History Rating Scale; and 2) the Semi-structured Interview for Depression, which inquires systematically among others, about hypomania, cyclothymia, hyperthymia and depressive temperament. Subjects were aged 29+/-6 years, and predominantly male (76.2%). RESULTS Univariate and multivariate analyses provided correlations in favour of a link between current cocaine abuse and double diagnosis, with special relevance to the bipolar spectrum, as well as psychotic disorders (p<0.0001). LIMITATION The modality of access to cocaine in different communities and the difficulty to distinguish cocaine use from abuse by the rating scale administered may have limited the interpretation of results. CONCLUSIONS If cocaine abuse precedes that of heroin or is concomitant, heroin may hypothetically serve as a "mood balancer" which transiently dampens subthreshold excitatory states and mood swings. Our data further suggest the need for a more complex model linking cocaine and bipolarity: subthreshold bipolarity, including hyperthymic and cyclothymic temperaments, seems to predispose to heroin addiction, but craving for the suppressed hypomania in turn could lead to cocaine abuse, which eventually unmasks a frank bipolar disorder - in some cases leading to mixed state, severe mania, as well as psychosis beyond mania. Prospective observations would shed further insight on this complex interface of major clinical and public health importance.

Ann Gen Psychiatry 2007; 6:31.

Abstract
BACKGROUND Mental symptoms are common in heroin addiction and may arise from issues of addiction and withdrawal, raising doubts about the patients truly having co-morbid psychiatric diagnoses. METHODS We studied the mental status of 1090 heroin addicts (831 males and 259 females aged between 16 and 51 years) at the beginning of treatment, and its relationship to relevant demographic and clinical data through the use of standardised instruments. RESULTS A total of 506 (46.42%) heroin addicts showed depressive-anxious symptomatology, 421 (38.62%) had psychomotor excitement and 163 (14.95%) demonstrated a psychotic state. Patients with depressive-anxious symptomatology on the whole had a less severe addictive illness compared to those demonstrating excited and psychotic symptoms. The presence of depressive-anxious features was felt to not necessarily be indicative of the presence of a dual diagnosis. CONCLUSION The presence of depressive-anxious symptomatology in the clinical presentation in heroin addicts appears to be unrelated to 'dual diagnosis'.

Enhanced suppression of adrenocorticotropic hormone and cortisol responses to hypothalamic-pituitary-adrenal function and thyrotropin-releasing hormone tests after stressful life events in patients with major depressive disorder. Neuropsychobiology 2007; 55:21-7.

Abstract
BACKGROUND It is commonly believed that there exists a relationship between the outcome of thyrotropin-releasing hormone (TRH) test, the combined dexamethasone/corticotropin-releasing hormone (DEX/CRH) test and stressful life events (SLEs) in major depressive disorder. OBJECTIVE SLEs influence the TRH and DEX/CRH tests in major depressive disorder when administered at the time of admission and improvement. METHODS The TRH and DEX/CRH tests were administered to patients hospitalized for major depressive disorders - on the 4th through the 7th hospital day and at the time of improvement. We measured DeltaMAX TSH, DeltaMAX ACTH, ACTH AUC, DeltaMAX cortisol, cortisol AUC, DeltaMAX ACTH/DeltaMAX TSH and DeltaMAX cortisol/DeltaMAX TSH. RESULTS SLEs were significantly negatively associated with DeltaMAX ACTH, ACTH AUC and cortisol AUC at the time of admission. However, these relationships lost significance at the time of improvement. The sample (41 patients at the time of admission, 18 patients at the time of improvement) was relatively small, which may have contributed to false-negative results. CONCLUSION SLEs may be negatively associated with the outcome of the DEX/CRH tests in major depressive disorder. The hypothalamic-pituitary-adrenal axis in the DEX/CRH test was modulated by SLEs.

Abstract
BACKGROUND Some recent reports raised the question whether unipolar mania, without severe or mild depression, really exists and whether it defines a distinct disorder. Literature on this topic is still scarce, although this was a matter of debate since several decades. METHOD Eighty-seven inpatients with Diagnostic and Statistical Manual of Mental Disorder, Revised Third Edition, manic episode and at least 3 major affective episodes, in 10 years of illness duration, were systematically evaluated to collect demographic and clinical information. The symptomatological evaluation was conducted by means of the Comprehensive Psychopathological Rating Scale. Clinical features, social disability, first-degree family history, and temperaments were compared between unipolar and bipolar manics. RESULTS Nineteen (21.8%) of 87 patients presented a course of illness characterized by recurrent unipolar manic episodes without history of major or mild depression (MAN). When this group was compared with 68 (78.2%) manic patients with a previous history of depressive episodes (BIP), we found substantial similarities in most demographic, familial, and clinical characteristics. MAN group reported more congruent psychotic symptoms and more frequent chronic course of the current episode in comparison to BIP group. In the MAN patients, we also observed a high percentage of hyperthymic temperament and a complete absence of depressive temperament. This latter difference was statistically significant. MAN patients compared with BIP ones also reported lower severity scores in social, familial, and work disability, and they showed less depressive features, hostility, and anxiety. CONCLUSION The numerous demographic, clinical, and psychopathological overlapping characteristics in unipolar and bipolar mania raise questions about the general nosographic utility of this categorization. Nonetheless, our data suggest a clinical and prognostic validity of keeping unipolar manic patients as a separate subgroup, in particular, as social adjustment and disability are concerned.

Psychopathology 2007; 40:269-77.

Abstract
BACKGROUND To describe the prevalence and the risk factors of suicidal ideation in a cohort of Italian opioid addicts presenting for treatment. METHOD Systematic cross-sectional clinical data on suicidal ideation, socio-demographic variables, psychiatric status, social adjustment, status and history of addiction in 616 patients were gathered. RESULTS Suicidal thoughts during the past week were reported by 29.1%. Suicidal thoughts were more frequent in patients with bipolar spectrum diagnoses (OR = 1.42) and in patients with depressive and aggressive symptoms (multiple R = 0.47). The odds of having suicidal thoughts were also higher for subjects receiving public welfare benefits (OR = 1.69), unemployed patients (OR = 1.37), those with early onset of heroin dependence (OR = 1.36), living alone (OR = 1.33), and experiencing problems in organizing social contacts and leisure time (OR = 1.28). CONCLUSION Current suicidal ideation was a common feature of patients with opioid addiction. Depression and hostility as part of the bipolar spectrum - in the context of early-onset drug dependence, work and social/leisure problems - appear independently associated with suicidal ideation. Given the elevated rates of completed suicide in heroin addiction, these data have implications for preventing suicide in patients with this type of addiction. Prospective data are needed to further address this important clinical and public health agenda.
