Clinical and demographic correlates of stigma in first-episode psychosis: the impact of duration of untreated psychosis.

OBJECTIVE: To evaluate the relationships between perceived stigma and duration of untreated psychosis (DUP), demographic characteristics, and clinical and psychosocial functioning in persons with a first episode of psychosis (FEP). METHOD: A total of 399 participants with FEP presenting for treatment at 34 sites in 21 states throughout the United States were evaluated using standardized instruments to assess diagnosis, symptoms, psychosocial functioning, perceived stigma, wellbeing, and subjective recovery. RESULTS: Perceived stigma was correlated with a range of demographic and clinical variables, including DUP, symptoms, psychosocial functioning, and subjective experience. After controlling for symptom severity, perceived stigma was related to longer DUP, schizoaffective disorder diagnosis, more severe depression, and lower wellbeing and recovery. The associations between stigma and depression, wellbeing, and recovery were stronger in individuals with long than short DUP, suggesting the effects of stigma on psychological functioning may be cumulative over the period of untreated psychosis. CONCLUSION: The findings suggest that independent of symptom severity, perceived stigma may contribute to delay in seeking treatment for FEP, and this delay may amplify the deleterious effects of stigma on psychological functioning. The results point to the importance of reducing DUP and validating interventions targeting the psychological effects of stigma in people with FEP.

A prospective longitudinal study of the impact of early postnatal vs. chronic maternal depressive symptoms on child development.

BACKGROUND: Few studies of the effects of postnatal depression on child development have considered the chronicity of depressive symptoms. We investigated whether early postnatal depressive symptoms (PNDS) predicted child developmental outcome independently of later maternal depressive symptoms. METHODS: In a prospective, longitudinal study, mothers and children were followed-up from birth to 2 years; repeated measures of PNDS were made using the Edinburgh Postnatal Depression Scale (EPDS); child development was assessed using the Bayley Scales II. Multilevel modelling techniques were used to examine the association between 6 week PNDS, and child development, taking subsequent depressive symptoms into account. RESULTS: Children of mothers with 6 week PNDS were significantly more likely than children of non-symptomatic mothers to have poor cognitive outcome; however, this association was reduced to trend level when adjusted for later maternal depressive symptoms. CONCLUSION: Effects of early PNDS on infant development may be partly explained by subsequent depressive symptoms.

Allergy to betalactam antibiotics in children: a prospective follow-up study in retreated children after negative responses in skin and challenge tests.

BACKGROUND: Up to 10% of the patients in whom suspected betalactam hypersensitivity (HS) has been excluded by skin and challenge tests report suspected allergic reactions during subsequent treatments with the same or very similar betalactams. It has been suggested that the reactions may result from a resensitization induced by the challenge performed at the time of the allergological work-up. However, most patients did not undergo a second allergological work-up, to determine if the reactions resulted from betalactam HS or not. OBJECTIVES: We aimed to determine if children diagnosed nonallergic to betalactams have tolerated subsequent treatments with the initially suspected and/or other betalactams, and, in case of a reaction, if the reaction resulted from betalactam HS. METHODS: We sent a questionnaire concerning the clinical history of their children to the parents of 256 children previously diagnosed nonallergic to betalactams. A second allergological work-up was performed in the children reporting suspected allergic reactions during subsequent treatments with the same and/or other betalactams. Skin tests were performed with the soluble form of the suspected (or very similar) betalactams and other betalactams from the same and other classes. Skin test responses were assessed at 15-20 min (immediate), 6-8 h (semi-late) and 48-72 h (late). Oral challenge (OC) was performed in children with negative skin tests, either at the hospital (immediate and accelerated reactions), or at home (delayed reactions). RESULTS: A response was obtained from 141 children (55.3%). Forty-eight (34%) of those children had not been treated with the betalactams for whom a diagnosis of allergy had been ruled out previously. Seven (7.5%) of the 93 children who had been treated again reported suspected allergic reactions. Skin tests and OC were performed in six of those children, and gave negative results in five children. In one child previously diagnosed nonallergic to amoxicillin associated with clavulanic acid, we diagnosed a delayed HS to clavulanic acid and a serum sickness-like disease to cefaclor. Thus, the frequency of reactions resulting from betalactam HS in children with negative skin and challenge tests is very low, and does not exceed 2.1% (2/93) if we consider that the child which refused a second allergological work-up is really allergic to betalactams. CONCLUSION: Our results in a very large number of children show that reactions presumed to result from betalactam HS are rare in children in whom the diagnosis of betalactam allergy has been ruled out previously. Moreover, they suggest that, as shown for the initial reactions, most of the reactions during subsequent treatments are rather a consequence of the infectious diseases for whom betalactams have been prescribed than a result of betalactam HS. Finally, they suggest that the risk of resensitization by OC is very low, and do not support the notion that skin testing should be repeated in children diagnosed nonallergic to betalactams.

Validating affective temperaments in their subaffective and socially positive attributes: psychometric, clinical and familial data from a French national study.

BACKGROUND: One of the major objectives of the French National EPIDEP Study was to show the feasibility of systematic assessment of bipolar II (BP-II) disorder and beyond. In this report we focus on the utility of the affective temperament scales (ATS) in delineating this spectrum in its clinical as well as socially desirable expressions. METHODS: Forty-two psychiatrists working in 15 sites in four regions of France made semi-structured diagnoses based on DSM IV criteria in a sample of 452 consecutive major depressive episode (MDE) patients (from which bipolar I had been removed). At least 1 month after entry into the study (when the acute depressive phase had abated), they assessed affective temperaments by using a French version of the precursor of the Temperament Evaluation of Memphis, Pisa, Paris and San Diego (TEMPS). Principal component analyses (PCA) were conducted on hyperthymic (HYP-T), depressive (DEP-T) and cyclothymic (CYC-T) temperament subscales as assessed by clinicians, and on a self-rated cyclothymic temperament (CYC-TSR). Scores on each of the temperament subscales were compared in unipolar (UP) major depressive disorder versus BP-II patients, and in the entire sample subdivided on the basis of family history of bipolarity. RESULTS: PCAs showed the presence of a global major factor for each clinician-rated subscale with respective eigenvalues of the correlation matrices as follows: 7.1 for HYP-T, 6.0 for DEP-T, and 4.7 for CYC-T. Likewise, on the self-rated CYC-TSR, the PCA revealed one global factor (with an eigenvalue of 6.6). Each of these factors represented a melange of both affect-laden and adaptive traits. The scores obtained on clinician and self-ratings of CYC-T were highly correlated (r=0.71). The scores of HYP-T and CYC-T were significantly higher in the BP-II group, and DEP-T in the UP group (P<0.001). Finally, CYC-T scores were significantly higher in patients with a family history of bipolarity. CONCLUSION: These data uphold the validity of the affective temperaments under investigation in terms of face, construct, clinical and family history validity. Despite uniformity of depressive severity at entry into the EPIDEP study, significant differences on ATS assessment were observed between UP and BP-II patients in this large national cohort. Self-rating of cyclothymia proved reliable. Adding the affective temperaments-in particular, the cyclothymic-to conventional assessment methods of depression, a more enriched portrait of mood disorders emerges. More provocatively, our data reveal socially positive traits in clinically recovering patients with mood disorders.

[Frequency and clinical aspects of bipolar II disorder in a French multicenter study: EPIDEP]. / Fréquence et aspects cliniques du trouble bipolaire II dans une étude multicentrique française: EPIDEP.

This paper presents the definite data from a French multi-center study (EPIDEP). The aim of EPIDEP was to show the feasibility of validating the spectrum of soft bipolar disorders by practicing clinicians. In this report we focus on data concerning the frequency of BP-II disorder and the key characteristics of BP-II by systematic comparison versus Unipolar depression. EPIDEP involved training 48 french psychiatrists in 15 sites; it is based on a common protocol following the DSM IV criteria (Semi-Structured Interview for Hypomania and Major Depression), and Akiskal (Soft Bipolarity), as well as criteria modified from the work of Angst (Hypomania Checklist), the Ahearn-Carroll Bipolarity Scale, HAM-D and Rosenthal Atypical Depression Scale; Semi-Structured Interview for Affective Temperaments (based on Akiskal-Mallya), self-rated Cyclothymia Scale (Akiskal). Comorbidity and family history (Research Diagnostic Criteria) were also obtained; EPIDEP was globally scheduled in two phases: Phase 1 devoted to recruiting major depressives, and phase 2 involved in more sophisticated assessment of soft bipolarity and administrating related measures. Results are presented on the total of 537 patients included at "visit 1" and 493 assessed for soft bipolarity at "visit 2". The BP-II global rate which was 21.7% at initial evaluation, nearly doubled (39.8%) by systematic evaluation of hypomania. Intergroup comparison versus unipolar depressives showed the following key characteristics of BP-II disorder: 1) distinct clinical presentation at index depressive episode despite uniformity in global intensity of depression (overrepresentation in BP-II of "suicidal thoughts", "guilt feelings", "depersonalisation-derealisation", "hypersomnia" "and weight gain"; and of "psychic anxiety" and "initial insomnia" in UP); 2) different course of illness with younger age of onset of first depression, higher rate of suicidal attempts, recurrency and hospitalisations; 3) more difficulties for recognition of the correct diagnosis; 4) more complex temperamental dysregulations (mixture of cyclothymic, hyperthymic and irritable traits which are highly represented in BP-II group); 5) higher rate in family history of mental disorders, especially bipolar disorders. Finally, EPIDEP data confirmed the diagnostic reliability of self-rating of hypomania and cyclothymia. With a systematic search of hypomania, almost 40% of major depressive episodes seen in psychiatric settings were classified as BP-II, of which only half were recognized by the clinicians at study inclusion. The BP-II validity as a distinct disorder from Unipolars was confirmed. Moreover, EPIDEP emphasized the reliability of self-rating in assessing soft-bipolarity (hypomania and cyclothymia). In total, EPIDEP data indicated that recognition of BP-II is feasible in diverse practice settings and proposed for clinicians some adapted clinical tools for assessing soft bipolarity.

Toward a refined phenomenology of mania: combining clinician-assessment and self-report in the French EPIMAN study.

BACKGROUND: Because manic patients lack insight, they are generally considered unreliable observers of their own psychopathology. The present analyses sought to examine to what extent patient reports could improve formal diagnostic criteria for mania--and be validated against the Carroll-Klein (CK) psychobiological model of bipolarity. METHOD: 104 DSM-IV acutely manic (hospitalized) patients provided self-assessment on the Ahearn--Carroll scale, the Multiple Visual Analogue Scales of Bipolarity (MVAS-BP). A principal component analysis (PCA) was performed on MVAS-BP, and the data on factorial scores were then compared to dimensional scores according to the CK model and to factors on the Beigel-Murphy Manic State Rating Scale (MSRS) completed by psychiatrists. RESULTS: The PCA identified a general factor accounting for 33% of the total variance; after varimax rotation, seven independent factors emerged, essentially in coherence with the signs and symptoms of DSM-IV mania, except for the 'social disinhibition' factor, which does not figure out as a distinct criterion in DSM-IV. Strong correlations were obtained (r > or = 0.80) between the four major factors of MVAS-BP and the four dimensional categories of the CK model: 'Consummatory Reward' with F1 'Elation and Inflated Self-esteem' (r=0.93), 'Incentive Reward' with F2 'Activation' (r=0.84), 'Psychomotor Pressure' with F3 'Acceleration' (r=0.85), and 'Central Pain' with F4 'Anxiety-Depression' (r=0.84). The F2 'Activation' appeared to be strongly correlated (r > or = 0.70) to all categories of the CK model. Correlational analysis between the factor structure of MVAS-BP and the MSRS showed significant coefficients on the scores assessing the emotional factors of 'Elation' and 'Depression.' Among the MVAS-BP factors, only 'Activation' was correlated to the majority of clinician ratings as obtained by the MSRS. CONCLUSIONS: These findings provide overall construct validity to the DSM-IV criteria for mania. Self-assessment of this disorder appears feasible and potentially useful in practice; lack of insight, poor judgment, and distractibility obviously require assessment by a clinician. Although our data are correlational and require prospective validation, they nonetheless suggest that (1) activation should be raised to the status of the stem criterion for mania, (2) to specify mood as elated, depressive, anxious, or irritable, and (3) to give individual status to social disinhibition (indiscriminate gregariousness) as a core pathological behavior in mania. Combining clinician- and self-observation thus produces a more precise and complete phenomenology of mania. We finally submit that the foregoing reformulation provides a psychobiological basis to the manic construct as formulated in the Carroll-Klein model.

The feasibility of self-assessment of dysphoric mania in the French national EPIMAN study.

BACKGROUND: There is presently considerable uncertainty on how to best assess mixed mania. The present contribution explores the feasibility of discriminating manic and dysphoric manic states on the basis of self-rating in the acute phase of the illness. METHODS: In the French four-site national EPIMAN study of 104 patients devoted to the clinical evaluation and subclassification of mania, we used the Multiple Visual Analog Scales of Bipolarity (MVAS-BP, 26 items) of Ahearn-Carroll in a self-assessment format. The study was conducted on consecutive patients hospitalized for an acute DSM-IV mania. The severity of mania was measured by the Beigel-Murphy scale (MSRS) assessed by psychiatrists. When mania abated, temperaments according to Akiskal and Mallya were administered in their French version. RESULTS: Principal component analysis revealed a general factor explaining 33% of the variance and, after rotation, seven factors defining different dimensions of the phenomenology of mania. The factorial scores, as well as the dimensional scores of the Carrol-Klein model significantly distinguished pure versus dysphoric mania made on clinical grounds. Gender seemed to influence two factors: high 'anxious-depressive' score in females (which is in line with female overrepresentation in mixed mania), vs. high score in males on the 'gregariousness' factor (which represents social disinhibition of the hyperthymic temperament known to be more prevalent in men). LIMITATION: Cross-sectional correlational study in need of longitudinal validation. CONCLUSIONS: EPIMAN data deriving from a national clinical population showed the feasiblity and face validity of self-assessment in acute mania, in particular its dysphoric subtype. Temperament in women seemed to contribute to the genesis of mixed (dysphoric) mania in accordance with Akiskal's hypothesis of opposition of temperament and polarity of bipolar episodes in mixed states. Self-assessment was capable of capturing accurately the subthreshold depressive symptomatology of mixed mania, which can be missed in hetero-evaluation by hasty clinical interview.

Re-evaluating the prevalence of and diagnostic composition within the broad clinical spectrum of bipolar disorders.

Until recently it was believed that no more than 1% of the general population has bipolar disorder. Emerging transatlantic data are beginning to provide converging evidence for a higher prevalence of up to at least 5%. Manic states, even those with mood-incongruent features, as well as mixed (dysphoric) mania, are now formally included in both ICD-10 and DSM-IV. Mixed states occur in an average of 40% of bipolar patients over a lifetime; current evidence supports a broader definition of mixed states consisting of full-blown mania with two or more concomitant depressive symptoms. The largest increase in prevalence rates, however, is accounted for by 'softer' clinical expressions of bipolarity situated between the extremes of full-blown bipolar disorder where the person has at least one manic episode (bipolar I) and strictly defined unipolar major depressive disorder without personal or family history for excited periods. Bipolar II is the prototype for these intermediary conditions with major depressions and history of spontaneous hypomanic episodes; current evidence indicates that most hypomanias pursue a recurrent course and that their usual duration is 1-3 days, falling below the arbitrary 4-day cutoff required in DSM-IV. Depressions with antidepressant-associated hypomania (sometimes referred to as bipolar III) also appear, on the basis of extensive international research neglected by both ICD-10 and DSM-IV, to belong to the clinical spectrum of bipolar disorders. Broadly defined, the bipolar spectrum in studies conducted during the last decade accounts for 30-55% of all major depressions. Rapid-cycling, defined as alternation of depressive and excited (at least four per year), more often arise from a bipolar II than a bipolar I baseline; such cycling does not in the main appear to be a distinct clinical subtype - but rather a transient complication in 20% in the long-term course of bipolar disorder. Major depressions superimposed on cyclothymic oscillations represent a more severe variant of bipolar II, often mistaken for borderline or other personality disorders in the dramatic cluster. Moreover, atypical depressive features with reversed vegetative signs, anxiety states, as well as alcohol and substance abuse comorbidity, is common in these and other bipolar patients. The proper recognition of the entire clinical spectrum of bipolarity behind such 'masks' has important implications for psychiatric research and practice. Conditions which require further investigation include: (1) major depressive episodes where hyperthymic traits - lifelong hypomanic features without discrete hypomanic episodes - dominate the intermorbid or premorbid phases; and (2) depressive mixed states consisting of few hypomanic symptoms (i.e., racing thoughts, sexual arousal) during full-blown major depressive episodes - included in Kraepelin's schema of mixed states, but excluded by DSM-IV. These do not exhaust all potential diagnostic entities for possible inclusion in the clinical spectrum of bipolar disorders: the present review did not consider cyclic, seasonal, irritable-dysphoric or otherwise impulse-ridden, intermittently explosive or agitated psychiatric conditions for which the bipolar connection is less established. The concept of bipolar spectrum as used herein denotes overlapping clinical expressions, without necessarily implying underlying genetic homogeneity. In the course of the illness of the same patient, one often observes the varied manifestations described above - whether they be formal diagnostic categories or those which have remained outside the official nosology. Some form of life charting of illness with colored graphic representation of episodes, stressors, and treatments received can be used to document the uniquely varied course characteristic of each patient, thereby greatly enhancing clinical evaluation.

Diabetes as a result of atypical anti-psychotic drugs--a report of three cases.

AIMS: Atypical anti-psychotic drugs (APDs) are widely used in psychotic disorders refractory to conventional neuroleptic agents. RESULTS: Three cases of new-onset diabetes are reported in Caucasian men who were on clozapine (one) or olanzapine (two) for 3-6 months. They had a distinct presentation: weight loss, ketosis (one ketoacidosis), severe hyperglycaemia requiring insulin therapy, and relative insulin deficiency as reflected by glucagon stimulatory tests. In all cases, insulin was stopped within 1 month after the APD was discontinued. CONCLUSIONS: Novel APDs not only induce diabetes as a result of weight gain in predisposed patients, but can also lead to a reversible state of insulin deficiency, and sometimes ketoacidosis.

Increased occurrence of depression in psychosis-prone subjects: a follow-up study in primary care settings.

A follow-up survey was performed with a network of general practitioners (GPs) to examine whether a higher proneness for psychosis predicts a greater incidence of depression in subjects with no history of mood disorder. At the first stage of the survey (T1), a self-report questionnaire exploring delusional ideation (Peters et al. Delusional Inventory [PDI-21]) was administered to the patients of the GPs. Information on psychiatric status at the baseline and conclusion of the 12-month follow-up period was provided by the GPs. The present study was restricted to 425 subjects with no lifetime history of depression. An incident depression was diagnosed in 18 subjects. Most items exploring delusional beliefs and hallucinations were more frequently endorsed by subjects with incident depression. Subjects with a PDI-21 score above the 90th percentile at T1 were nine times more likely to present with an incident depression during the follow-up period than those with PDI-21 scores below the 10th percentile. Psychosis proneness is associated with a greater risk for depression, suggesting that a continuum of vulnerability may exist between affective disorder and nonaffective psychosis.

Temperament in bipolar illness: impact on prognosis.

OBJECTIVE: The present study was designed to investigate the relations between temperament and outcome in bipolar illness. METHODS: Seventy-two patients presenting with bipolar type I disorder were recruited from consecutive admissions and evaluated when euthymic. The criteria developed by Akiskal and Mallya (Criteria for the 'soft' bipolar spectrum: treatment implications. Psychopharmacol. Bull. 1987;23:68-73) were used to assess both depressive (DT) and hyperthymic temperaments (HT) in a dimensional approach. RESULTS: Multiple regression analysis showed that a higher DT score or a lower HT score were significantly associated with a greater number of episodes. Furthermore, a higher DT score was strongly associated with a higher percentage of major depressive episodes. Conversely, a higher HT score was associated with a trend to manic rather than depressive episodes. Suicide attempts appeared more frequent in the history of patients presenting with higher DT scores. CONCLUSIONS: Our findings strengthen the hypothesis that temperament is one of the main variables accounting for some features in the clinical evolution of bipolar disorder such as polarity of episodes. Furthermore, these findings are consistent with the hypothesis of a trait-state continuum between personality and affective episodes.

Gender, temperament, and the clinical picture in dysphoric mixed mania: findings from a French national study (EPIMAN).

BACKGROUND: This research derives from the French national multisite collaborative study on the clinical epidemiology of mania (EPIMAN). Our aim is to establish the validity of dysphoric mania along a "spectrum of mixity" extending into mixed mania with subthreshold depressive manifestations; to demonstrate the feasibility of obtaining clinically meaningful data on this entity on a national level; and to characterize the contribution of temperamental attributes and gender in its origin. METHODS: EPIMAN involves training 23 French psychiatrists in four different sites, representing four regions of France; to rigorously apply a common protocol deriving from the criteria of DSM-IV and McElroy et al.; the use of such instruments as the Beigel-Murphy, Ahearn-Carroll, modified HAM-D; and measures of affective temperaments based on the Akiskal-Mallya criteria; obtaining data on comorbidity, and family history (according to Winokur's approach as incorporated into the FH-RDC); and prospective follow-up for at least 12 months. The present report concerns the clinical and temperamental features of 104 manic patients during the acute hospital phase. RESULTS: Dysphoric mania (DM defined conservatively with fullblown depressive admixtures of five or more symptoms) occurred in 6.7%; the rate of dysphoric mania defined broadly (DM, presence of > or = 2 depressive symptoms) was 37%. Depressed mood and suicidal thoughts had the best positive predictive values for mixed mania. In comparison to pure mania (0-1 depressive symptoms), DM was characterized by female over-representation; lower frequency of such typical manic symptomatology as elation, grandiosity, and excessive involvement; higher prevalence of associated psychotic features; higher rate of mixed states in first episodes; and complex temperamental dysregulation along primarily depressive, but also cyclothymic, and irritable dimensions; such irritability was particularly apparent in mixed mania at the lowest threshold of depressive admixtures of two symptoms only. LIMITATION: In a study involving hospitalized affectively unstable psychotic patients, it was difficult to assure that psychiatrists making the clinical diagnoses would be blind to the temperamental measures. However, bias was minimized by the systematic and/or semi-structured nature of all evaluations. CONCLUSIONS: Mixed mania, defined cross-sectionally by the simultaneous presence of at least two depressive symptoms, represents a prevalent and clinically distinct form of mania. Subthreshold depressive admixtures with mania actually appear to represent the more common expression of dysphoric mania. Moreover, an irritable dimension appears to be relevant to the definition of the expression of mixed mania with the lowest threshold of depressive symptoms. Neither an extreme, nor an endstage of mania, "mixity" is best conceptualized as intrusion of mania into its "opposite" temperament - especially that defined by lifelong depressive traits - and favored by female gender. These data suggest that reversal from a temperament to an episode of "opposite" polarity represents a fundamental aspect of the dysregulation that characterizes bipolar disorder. In both men and women with hyperthymic temperament, there appears "protection" against depressive symptom formation during a manic episode which, accordingly, remains relatively "pure". Because men have higher rates of this temperament, pure mania is overrepresented in men; on the other hand, the depressive temperament in manic women seems to be a clinical marker for the well-known female tendency for depression, hence the higher prevalence of mixed mania in women.
