Antecedents of manic versus other first psychotic episodes in 263 bipolar I disorder patients.

OBJECTIVE: As initial episode type can predict later morbidity in bipolar disorder, we tested the hypothesis that clinical antecedents might predict initial episode types. METHOD: We studied 263 first-episode, adult, DSM-IV-TR type I bipolar disorder (BD-I) subjects within the McLean-Harvard-International First-Episode Project. Based on blinded assessments of antecedents from SCID examinations and clinical records, we compared first lifetime manic vs. other (mixed, depressive, or non-affective) major psychotic episodes. RESULTS: We identified 32 antecedents arising at early, intermediate or later times, starting 12.3±10.7 years prior to first lifetime major psychotic episodes. Based on multivariate modeling, antecedents associated significantly and independently with other (n=113) more than manic (n=150) first lifetime major psychotic episodes ranked by odds ratio: more early attentional disturbances, more late depression, more early perplexity, more detoxification, more early unstable mixed affects, more antidepressants, more early dysphoria, more intermediate depression, more early impulsivity, more late anhedonia, longer early-to-intermediate intervals, more intermediate substance abuse, more family history of major depression, and younger at earliest antecedents. Antecedents selectively preceding manic more than other first psychotic episodes included more late behavioral problems and more risk of familial BD-I. CONCLUSION: Clinical antecedents in adult, BD-I patients, beginning a decade before first major episodes and progressing through sequential stages were dissimilar in manic vs. other first psychotic episodes.

Psychopathology factors in first-episode affective and non-affective psychotic disorders.

BACKGROUND: Since the onset, prevalence, and course of specific psychopathological features rarely have been analyzed simultaneously from the start of dissimilar psychotic illnesses, we compared symptom-clusters in first-episode DSM-IV affective and non-affective psychotic disorders. METHODS: Subjects (N=377) from the McLean-Harvard First Episode Project hospitalized for first-lifetime primary psychotic illnesses were followed prospectively for 2 years to verify stable DSM-IV diagnoses. We ascertained initial symptoms from baseline SCID and clinical assessments, applying AMDP and Bonn psychopathology schemes systematically to describe a broad range of features. Final consensus diagnoses were based on intake and follow-up SCID assessments, family interviews, and medical records. Factor-analytic methods defined first-episode symptom-clusters (Factors), and multiple-regression modeling related identified factors to initial DSM-IV diagnoses and to later categories (affective, non-affective, or schizoaffective disorders). RESULTS: Psychopathological features were accommodated by four factors: I represented mania with psychosis; II a mixed depressive-agitated state; III an excited-hallucinatory-delusional state; IV a disorganized-catatonic-autistic state. Each factor was associated with characteristic prodromal symptoms. Factors I and III associated with DSM-IV mania, II with major depression or bipolar mixed-state, III negatively with delusional disorder, IV with major depression and negatively with mania. Factors I and II predicted later affective diagnoses; absence of Factor I features predicted non-affective diagnoses, and no Factor predicted later schizoaffective diagnoses. CONCLUSION: The findings contribute to descriptive categorizations of psychopathology from onset of dissimilar psychotic illnesses. This approach was effective in identifying and subtyping affective psychotic disorders early in their clinical evolution, but non-affective and schizoaffective conditions appear to be more complex and unstable.

Psychopathology, personality, and marital relationship in patients undergoing in vitro fertilization procedures.

OBJECTIVE: To compare the psychopathology, personality features, and marital relationships of women undergoing in vitro fertilization (IVF) with those of control patients, and to compare IVF inductees with program veterans. DESIGN: Cross-sectional clinical study. SETTING: A university hospital. PATIENT(S): One hundred and one women undergoing IVF treatment. INTERVENTION(S): Psychometric tests were administered at first visit (baseline) of index treatment cycle. MAIN OUTCOME MEASURE(S): Achievement of pregnancy. RESULT(S): Women undergoing IVF show higher levels of anxiety and emotional tension than do controls. Although the infertile women showed no abnormal personality dimensions, the IVF group did have a particular psychological profile and a different marital relationship pattern when compared with the control participants. Between IVF veterans and inductees, there are significant differences with respect to psychopathology, psychological dimensions, and couple dynamics. The achievement of pregnancy is not associated with any special psychopathological, personality, or marital characteristics among the IVF women. CONCLUSION(S): The most crucial period in IVF procedures may immediately follow the end of the first cycle because of the high risk of patients dropping out of the program. To determine the most effective supporting therapies for women undergoing fertilization procedures it could be useful to consider the psychological and relational differences between veterans and inductees.

Temperament and personality features in patients with major depression, panic disorder and mixed conditions.

METHOD: Forty-two patients with Panic Disorder (P), 18 with Major Depression (MD), 35 with both conditions (MIX) and 45 healthy subjects (C) were tested with the Tridimensional Personality Questionnaire and the Structured Interview for DSM-III-R Personality Disorders. RESULTS: A different prevalence of Dependent (P = 16.7%, MD = 5.6%, MIX = 41.4%, C = 2.1%) (P < 0.001), Obsessive-Compulsive (P = 4.8%, MD = 27.8%, MIX = 3.4%, C = 0%) (P < 0.001) and Histrionic (P =23.8%, MD = 0%, MIX = 31%, C = 4.2%) (P = 0.001) personality disorders (PD) was found among groups. Harm Avoidance (HA) (P < 0.001) and Reward Dependence (RD) (P <0.001) were higher in patients than in controls. As expected the patients with comorbid conditions (MIX) showed higher HA levels (P < 0.01) and a greater prevalence of PDs, particularly of Cluster C compared to patients with pure disorders. CONCLUSIONS: This study suggests that high HA and RD scores are associated with P, MD and MIX, and the former dimension is even higher in MIX patients.

Are alexithymia, depression, and anxiety distinct constructs in affective disorders?

OBJECTIVE: the present study was undertaken to gain a better insight into the relationship between alexithymia, anxiety, and depression. Two hypotheses were tested: (1) whether a depressive or anxiety disorder is associated with an elevation of one or more dimensions of alexithymia; and (2) whether alexithymia is an independent construct from depression and anxiety in patients with depressive or anxiety disorders. METHOD: a total of 113 patients with depressive or anxiety disorders (DSM-IV) and 113 control subjects completed the 20-item version of the Toronto alexithymia scale (TAS-20) and the hospital anxiety and depression scale (HADS). RESULTS: the TAS-20 total score was higher in depressed and anxious patients than in controls. This finding mainly depended on an increased score for "difficulty identifying feelings"(DIF), and (only in depressed patients) on an increased score for "difficulty communicating feelings" (DCF). The factor analysis of the TAS-20 and HADS items showed that depression is a construct different from alexithymia, whereas some overlap exists between anxiety and DIF dimension. CONCLUSION: our results suggest that in depressive and anxiety disorders, alexithymia and depression are separate constructs that may be closely related; in contrast, there are some overlaps between the DIF dimension and anxiety.

Psychobiology of boredom.

The study of the psychobiological bases of boredom has been limited by the vagueness of its clinical constructs and the difficulties in applying adequate experimental models. The theoretical background of previous research mainly has been based upon cognitive and behavioral psychology by using neuropsychological constructs, such as arousal, attention, motivation, sensation-seeking, and the reward system. Recently acquired data depict a complex and fragmentary picture. In this article, the author presents a review of the literature as well as some personal considerations on this intriguing topic.

Anxiety and depressive disorders in an emergency department ward of a general hospital: a control study.

OBJECTIVE: In this study anxiety and depressive disorders were evaluated in patients admitted to an emergency department (ED) or to a medical department (MD). METHODS: The General Health Questionnaire-30 (GHQ-30) was administered to screen all patients (n = 719) consecutively admitted to an ED (n = 556) and to MD (n = 163) in a 120 day period. All GHQ-30 positive (score>4) underwent the Mini International Neuropsychiatric Interview, a structured interview to diagnose mental disorders according to DSM-IV criteria. RESULTS: Subjects positive to GHQ-30 were 264 (47%) in ED and 88 (54%) in MD. A mental disorder was diagnosed in 233 ED patients (42%) and in 77 MD patients (47%) (p = 0.70). The most frequent disorders were anxiety disorders in ED patients (18.1%) and depressive disorders in MD patients (21%) (p = 0.04). CONCLUSIONS: Anxious patients more frequently seek attention at ED, whereas patients with depressive disorders are more often observed in medical units. The improvement of quality of care, the waste of healthcare resources through unnecessary medical care, and the well known efficacy of appropriate treatments in patients with anxiety and depressive disorders make the diagnosis of these patients particularly important.

[Chronic depressions (author's transl)]. / Les dépressions chroniques.

The definition of chronic depression necessarily calls for a review of the concept of recovery which in psychopathology is not clearly and univocally defined. The percentage of chronic evolution among depressive patients either as a persistence of depressive symptoms or as an impairment of social and professional role, ranges from 12 to 15%. Chronic depression raises psychopathologic and nosographic problems as well as clinical ones. In fact chronic depressives are often not correctly diagnosed, inadequately treated and destined to be affected by an over increasing inability. The chronic evolution of depression may result as a concurrence of several factors: a neurotic personality, an inadequate antidepressant maintenance treatment, an inappropriated use of minor tranquillizers as the only treatment. The occurrence of physical impairement, the continuous nature of depression and the resistance of antidepressant treatment may be also considered. Moreover the psychodynamic mechanisms aroused by the depressive experience and the secondary advantages of the illness may plan an effective role maintaining depressive symptomatology.

Is alexithymia a personality trait increasing the risk of depression? A prospective study evaluating alexithymia before, during and after a depressive episode.

BACKGROUND: Whether alexithymia is a personality trait that increases the risk of major depression (MD) is still debated. In this prospective study, alexithymic levels were evaluated before, during and after a depressive episode. METHOD: The alexithymic levels, the presence of MD and the severity of anxious-depressive symptoms were evaluated at intervals of about 1 month in pregnant women attending the Centers for Prenatal Care, using the Toronto Alexithymia Scale (TAS), the Primary Care Evaluation of Mental Disorders (PRIME-MD) and the Hospital Anxiety and Depression Scale (HADS). RESULTS: Sixteen women affected by MD, 21 affected by subthreshold depression and 112 non-depressed women were included in the study. Women who developed depression, compared to non-depressed women, showed similar TAS and HADS scores during the pre-morbid phase, a significant increase in the scores during depression and a significant decrease after remission, whereas no change was observed in non-depressed women. CONCLUSIONS: Our data suggest that in pregnant women alexithymia does not represent a personality trait that increases the risk of developing a depressive episode, and they support the hypothesis that alexithymia is a state-dependent phenomenon in depressed pregnant women.

The effect of temperament and character on response to selective serotonin reuptake inhibitors in panic disorder.

OBJECTIVE: In this prospective study, temperament and character were evaluated in patients with panic disorder (PD), before 1 year of medication therapy, to verify whether these factors influenced the outcome of treatment. METHOD: Seventy-one PD patients were evaluated with the SCID-IV, the Temperament and Character Inventory (TCI), the SCL-90, the Ham-A and the Ham-D. Patients were treated with pharmacotherapy and were evaluated monthly over 1 year. RESULTS: Before treatment, non-remitted patients showed higher levels of harm avoidance (HA) and lower levels of persistence (P), self-directedness (SD) and cooperativeness (C), whereas remitted patients showed only higher levels of HA. After controlling the effect of the confounding variables, the likelihood to achieve remission was positively related to SD score (OR = 1.12; P = 0.002), particularly 'self-acceptance' SD dimension (OR = 1.30; P = 0.02). CONCLUSIONS: Our data suggest that in PD: i) the evaluation of personality, using the Cloninger's model, confirms the presence of personality pathology as one predictor of non-response to treatment; ii) in patients with low SD a combination of medication and cognitive-behaviour therapy should be the most effective treatment.

Predictors of symptom resolution in panic disorder after one year of pharmacological treatment: a naturalistic study.

OBJECTIVE: In this naturalistic and prospective study, patients with panic disorder (PD) were treated for one year 1) to verify the rate of patients achieving the resolution of full-symptom attacks, limited-symptom attacks, anticipatory anxiety, phobic avoidance and depression; and 2) to identify the predictors of symptom resolution for each domain. METHOD: One hundred patients with PD, according to DSM-IV criteria, participated in the study. In all patients, a baseline and a follow-up with monthly evaluations of SCL-90, Ham-A, Ham-D and panic diaries were carried out over a one-year period. All patients were treated with paroxetine or citalopram. RESULTS: Seventy-one patients completed the study, whereas the remaining 29 dropped out. Among completers, remission of full- and limited-symptom panic attacks was observed in 76 % of patients, whereas complete remission (resolution of panic attacks, anticipatory anxiety, phobic anxiety, and depression) was achieved by only 46 % of patients. Predictors of absence of symptom remissions were obsessive-compulsive disorder (OCD) and recurrent major depression (MD) comorbidity (for panic attacks), pre-treatment severity of anxious symptoms (for anticipatory anxiety), phobic anxiety (for phobic avoidance), and depressive symptoms (for depression). CONCLUSION: This naturalistic study shows that the high comorbidity of OCD and MD and the greater pre-treatment severity of anxious, phobic and depressive symptoms reduced the likelihood of achieving complete remission of symptoms in PD patients who completed the protocol, even though they were adequately treated with SSRI medication.

Chlorpromazine, clozapine and olanzapine inhibit anionic amino acid transport in cultured human fibroblasts.

We report here that chlorpromazine, a first generation antipsychotic drug, inhibits anionic amino acid transport mediated by system X(-) (AG) (EAAT transporters) in cultured human fibroblasts. With 30 microM chlorpromazine, transport inhibition is detectable after 3 h of treatment, maximal after 48 h (>60%), and referable to a decrease in V(max). Chlorpromazine effect is not dependent upon changes of membrane potential and is selective for system X(-) (AG) since transport systems A and y(+) are not affected. Among antipsychotic drugs, the inhibitory effect of chlorpromazine is shared by two dibenzodiazepines, clozapine and olanzapine, while other compounds, such as risperidon, zuclopentixol, sertindol and haloperidol, are not effective. Transport inhibition by clozapine and olanzapine, but not by chlorpromazine, is reversible, suggesting that the mechanisms involved are distinct. These results indicate that a subset of antipsychotic drugs inhibits EAAT transporters in non-nervous tissues and prompt further investigation on possible alterations of glutamate transport in peripheral tissues of schizophrenic patients.

Homicide in Capgras' syndrome.

A case of Capgras' syndrome associated with homicidal behavior is reported. The psychodynamic implications are discussed. Capgras' syndrome could lie at the base of aggressive and homicidal acts directed towards family members during psychotic breakdown. Capgras' syndrome should always be evaluated in order to prevent violent acts, understand the psychologic characteristics of the patient and undertake the corresponding treatment.

Temperament and personality features in panic disorder with or without comorbid mood disorders.

Personality and temperament features, assessed with the Structured Interview for DSM-III-R Personality Disorders-Revised (SIDP-R) and the Tridimensional Personality Questionnaire (TPQ), respectively, were evaluated in 62 patients affected by panic disorder with (PD + MD) (n = 22) or without comorbid mood disorder (PD) (n = 40). A significant difference in the prevalence of personality disorders (PD + MD, 86% vs. PD, 62%; P < 0.05), particularly dependent (PD + DM, 50% vs. PD, 17%; P < 0.01) and borderline (PD + DM, 9% vs. PD, 0%; P = 0.05) personality disorders, was observed between the groups. Moreover, patients in the PD + MD group had higher scores for harm avoidance (PD + MD, 22.2 +/- 5.6 vs. PD, 26.9 +/- 5.1; P < 0.05) than patients in the PD group. The harm avoidance score in PD patients was significantly related to personality disorder and not to MD, suggesting that harm avoidance is not associated with greater severity of the illness. Our data confirm the hypothesis that subjects with higher harm avoidance scores have a greater probability of being affected by cluster C personality disorders and comorbid mood and anxiety disorders.

The treatment of panic disorder in a clinical setting: a 12-month naturalistic study.

In the treatment of panic disorder double-blind controlled studies have demonstrated that imipramine (IMI) was effective at doses higher than 125 mg/day. However a high rate of dropouts because of side effects has been reported in these subjects. In clinical settings, the administration of benzodiazepines (BDZ) in combination with IMI has been proposed to reduce the frequency and severity of side effects. In this naturalistic study, 49 patients affected by panic disorder with agoraphobia (n = 36) or without agoraphobia (n = 13) were treated with IMI plus lorazepam (LRZ) and followed for 12 months. The mean effective doses were 63.5 +/- 35.5 mg/day for IMI and 2.4 +/- 1.3 mg/day for LRZ. During the follow-up period, panic attacks disappeared in 75.5% of patients and 69.5% of agoraphobics were free of phobic avoidance. The patients with comorbid mood disorders and longer duration of illness required higher doses of both drugs. The combined treatment of IMI and LRZ allowed the use of low doses of the drugs, reduced the frequency and severity of the side effects and improved patient compliance. In fact, only 1 patient (2%) dropped out because of the severity of side effects. Furthermore, the patients who tapered LRZ treatment did not show BDZ withdrawal syndrome.
