Forester BP, Ajilore O, Spino C, Lehmann S. Clinical Characteristics of Patients with Late Life Bipolar Disorder in the Community: Data from the NNDC Registry. Am J Geriatr Psychiatry 2015; 23:977-84. [PMID: 25670662 PMCID: PMC4503521 DOI: 10.1016/j.jagp.2015.01.001] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/09/2014] [Revised: 01/05/2015] [Accepted: 01/06/2015] [Indexed: 02/07/2023]
Abstract
OBJECTIVE To compare clinical characteristics of older and younger patients with bipolar disorder enrolled in the United States' National Network of Depression Centers (NNDC) Clinical Care Registry (CCR). DESIGN Multicenter, de-identified naturalistic data from the National NNDC's CCR for all patients with a diagnosis of bipolar disorder who were enrolled in the registry as of April 25, 2013. PARTICIPANTS Community-dwelling patients (N = 218), ages 18 years or older, with bipolar disorder diagnosis recruited by NNDC-affiliated medical centers to participate in the NNDC CCR. Subjects aged 55 years or older were compared with subjects younger than age 55 years on clinical measures. MEASUREMENTS Patient Health Questionnaire; Quick Inventory of Depressive Symptomatology - Self-Report; Altman Self-Rating Mania Scale; Work and Social Adjustment Scale; Frequency and Intensity of Burden of Side Effects Rating; and the Self-Administered Comorbidity Questionnaire. RESULTS A greater percentage of older patients were prescribed antidepressant medications (71.9% versus 50.0%), and the younger cohort had significantly more psychostimulant use (16.7% versus 0%). Younger patients endorsed significantly more depressive symptoms compared with older patients. The mean number of psychotropic medications was not different in both older and younger patients with bipolar disorder. There was no statistically significant difference in frequency, intensity, or burden of psychotropic medication side effects as measured by the Frequency and Intensity of Burden of Side Effects Rating. CONCLUSION Findings of higher antidepressant use rates in the older cohort, combined with lower depression symptom severity and a similar degree of manic symptoms, suggests the possibility that older adults with bipolar disorder may have improved antidepressant efficacy and lower switch rates into manic or mixed states compared with younger cohorts. Ongoing data collection by the NNDC CCR will add to current knowledge to inform the care of older patients with bipolar disorder by providing multi-site data regarding phenomenology, treatment response, and longitudinal course of late life bipolar disorder in community settings.

Abstract
BACKGROUND Mixed depression (MxD) is narrowly defined in the DSM-IV and somewhat broader in the DSM-5, although both exclude psychomotor agitation as a diagnostic criterion. This article proposes a clinical description for defining MxD, which emphasizes psychomotor excitation. METHODS Two hundred and nineteen consecutive outpatients were diagnosed with an MxD episode using criteria proposed by Koukopoulos et al. [Acta Psychiatr Scand 2007;115(suppl 433):50-57]; we here report their clinical features and antidepressant-related effects. RESULTS The most frequent MxD symptoms were: psychic agitation or inner tension (97%), absence of retardation (82%), dramatic description of suffering or weeping spells (53%), talkativeness (49%), and racing or crowded thoughts (48%). MxD was associated with antidepressants in 50.7% of patients, with similar frequency for tricyclic antidepressants (45%) versus selective serotonin reuptake inhibitors (38.5%). Positive predictors of antidepressant-associated MxD were bipolar disorder type II diagnosis, higher index depression severity, and higher age at index episode. Antipsychotic or no treatment was protective against antidepressant-associated MxD. CONCLUSIONS MxD, defined as depression with excitatory symptoms, can be clinically identified, is common, occurs in both unipolar depression and bipolar disorder, and is frequently associated with antidepressant use. If replicated, this view of MxD could be considered a valid alternative to the DSM-5 criteria for depression with mixed features.

Abstract
Sleep deprivation (SD) is the most widely documented rapid-onset antidepressant therapy, targeting the broadly defined depressive syndrome. Although SD responses are transient, its effects can be sustained by concomitant medications (e.g., selective serotonin reuptake inhibitors and lithium) and circadian-related interventions (e.g., bright light and sleep phase advance). Thus, considering its safety, this technique can now be considered among the first-line antidepressant treatment strategies for patients affected by mood disorders. SD is a complex intervention and it should be considered multi-target in nature. Thus, the mechanisms explaining its antidepressant effect can be looked for on many levels, involving not only monoaminergic mechanisms but also sleep homeostatic and circadian mechanisms, glutamatergic mechanisms and synaptic plasticity.

Abstract
OBJECTIVE The purpose of this study was to assess the risk of manic switch associated with antidepressants in Medicaid-enrolled pediatric patients with bipolar depression. METHODS This retrospective cohort study involved 2003-2007 Medicaid Analytic eXtract (MAX) data from four geographically diverse states. The study sample included children and adolescents (ages 6-18 years) who had received a diagnosis of bipolar disorder on two or more separate occasions or during a hospital discharge, followed by a diagnosis of depression. According to the pharmacotherapy received by these patients in the 30 days around the index bipolar depression diagnosis, patients were categorized into five mutually exclusive groups. Manic switch was defined as having received a diagnosis of mania within 6 weeks after the initiation of bipolar depression treatment. Relative risks of manic switch between antidepressant monotherapy/polytherapy and their alternatives were assessed using Cox proportional hazards model. The robustness of the conventional Cox proportional hazards model toward possible bias caused by unobserved confounders was tested using instrumental variable analysis, and the uncertainty regarding manic switch definition was tested by altering the duration of follow-up. RESULTS After applying all the selection criteria, 179 antidepressant monotherapy, 1047 second-generation antipsychotic (SGA) monotherapy, 570 mood stabilizer monotherapy, 445 antidepressant polytherapy, and 1906 SGA-mood stabilizer polytherapy users were identified. In Cox proportional hazard analyses, both antidepressant monotherapy and polytherapy exhibited higher risk of manic switch than their alternatives (antidepressant monotherapy vs. SGA monotherapy, hazard ratio [HR]=2.87 [95% CI: 1.10-7.49]; antidepressant monotherapy vs. mood stabilizer monotherapy, HR=1.41 [95% CI: 0.52-3.80); antidepressant polytherapy vs. SGA-mood stabilizer polytherapy, HR=1.61 [95% CI: 0.90-2.89]). However, only the comparison between antidepressant monotherapy and SGA monotherapy was statistically significant. The instrumental variable analysis did not detect endogeneity of the treatment variables. Extending the follow-up period from 6 weeks to 8 and 12 weeks generated findings consistent with the main analysis. CONCLUSIONS Study findings indicated a higher risk of manic switch associated with antidepressant monotherapy than with SGA monotherapy in pediatric patients with bipolar depression. The finding supported the clinical practice of cautious prescribing of antidepressants for brief periods.

Abstract
BACKGROUND Depression is the predominant pole of illness disability in bipolar disorder and, compared with acute mania, has less systematic research guiding treatment development. The aim of this review is to present the therapeutic options currently available for managing bipolar depression and to highlight areas of unmet need and future research. METHODS Literature search of PubMed, PsycINFO, and Cochrane databases and bibliographies from 2000 to August 2013 for treatments that have regulatory approval for bipolar depression or early controlled preliminary data on efficacy. RESULTS Treatment options for bipolar depression have increased over the last decade, most notably with regulatory approval for olanzapine/fluoxetine combination, quetiapine, and lurasidone. Conventional mood stabilizers lamotrigine and divalproex have meta-analyses suggesting acute antidepressant response. Manual-based psychotherapies also appear to be effective in treating bipolar depression. The therapeutic utility of unimodal antidepressants, as a class, for the treatment of patients with bipolar depression, as a group, remains to be confirmed. There is a substantially unmet need to develop new interventions that are efficacious, effective, and have low side effect burden. LIMITATIONS Additional compounds are currently being developed that may ultimately be applicable to the treatment of bipolar depression and early open-trial data encourage further studies, but both of these topics are beyond the scope of this review. CONCLUSION Future registrational trials will need to establish initial efficacy, but increasing interest for personalized or individualized medicine will encourage further studies on individual predictors or biomarkers of response.

Abstract
The DSM-5 definition of mixed features "specifier" of manic, hypomanic and major depressive episodes captures sub-syndromal non-overlapping symptoms of the opposite pole, experienced in bipolar (I, II, and not otherwise specified) and major depressive disorders. This combinatory model seems to be more appropriate for less severe forms of mixed state, in which mood symptoms are prominent and clearly identifiable. Sub-syndromal depressive symptoms have been frequently reported to co-occur during mania. Similarly, manic or hypomanic symptoms during depression resulted common, dimensionally distributed, and recurrent. The presence of mixed features has been associated with a worse clinical course and high rates of comorbidities including anxiety, personality, alcohol and substance use disorders and head trauma or other neurological problems. Finally, mixed states represent a major therapeutic challenge, especially when you consider that these forms tend to have a less favorable response to drug treatments and require a more complex approach than non-mixed forms.

Abstract
OBJECTIVES We reviewed the treatment of bipolar mixed states using efficacy data of licensed and non-licensed physical or pharmacological treatments. METHODS We conducted a literature search to identify published studies reporting data on mixed states. Grading was done using an in-house level of evidence and we compared the efficacy with treatment recommendations of mixed states in current bipolar disorder guidelines. RESULTS A total of 133 studies reported data on mixed states, and seven guidelines differentiate the acute treatment of mixed states from pure states. The strongest evidence in treating co-occurring manic and depressive symptoms was for monotherapy with aripiprazole, asenapine, extended release carbamazepine, valproate, olanzapine, and ziprasidone. Aripiprazole was recommended in three guidelines, asenapine in one, and carbamazepine and ziprasidone in two. As adjunctive treatment, the strongest evidence of efficacy was for olanzapine plus lithium or valproate. For maintenance, there is evidence for the efficacy of monotherapy with valproate, olanzapine, and quetiapine. In the six guidelines valproate or olanzapine are first line monotherapy options; one recommends quetiapine. Recommended add-on treatments are lithium or valproate plus quetiapine. CONCLUSIONS There is a lack of studies designed to address the efficacy of medications in mixed affective symptoms. Guidelines do not fully reflect the current evidences.

Abstract
First-line treatment of major depression includes administration of a selective serotonin reuptake inhibitor (SSRI), yet studies suggest that remission rates following two trials of an SSRI are <50%. The authors examine the putative biological substrates underlying "treatment resistant depression (TRD)" with the goal of elucidating novel rationales to treat TRD. We look at relevant articles from the preclinical and clinical literature combined with clinical exposure to TRD patients. A major focus was to outline pathophysiological mechanisms whereby the serotonin system becomes impervious to the desired enhancement of serotonin neurotransmission by SSRIs. A complementary focus was to dissect neurotransmitter systems, which serve to inhibit the dorsal raphe. We propose, based on a body of translational studies, TRD may not represent a simple serotonin deficit state but rather an excess of midbrain peri-raphe serotonin and subsequent deficit at key fronto-limbic projection sites, with ultimate compromise in serotonin-mediated neuroplasticity. Glutamate, serotonin, noradrenaline, and histamine are activated by stress and exert an inhibitory effect on serotonin outflow, in part by "flooding" 5-HT1A autoreceptors by serotonin itself. Certain factors putatively exacerbate this scenario - presence of the short arm of the serotonin transporter gene, early-life adversity and comorbid bipolar disorder - each of which has been associated with SSRI-treatment resistance. By utilizing an incremental approach, we provide a system for treating the TRD patient based on a strategy of rescuing serotonin neurotransmission from a state of SSRI-induced dorsal raphe stasis. This calls for "stacked" interventions, with an SSRI base, targeting, if necessary, the glutamatergic, serotonergic, noradrenergic, and histaminergic systems, thereby successively eliminating the inhibitory effects each are capable of exerting on serotonin neurons. Future studies are recommended to test this biologically based approach for treatment of TRD.

Abstract
BACKGROUND Racing thoughts, crowded thoughts and flight of ideas are frequent symptoms in mood disorders, but the underlying subjective experience of overactivation of thought processes remains poorly documented. METHODS Qualitative analysis of audiotaped interviews explored subjective experience of thought overactivation in patients with mood disorders (sample 1, n = 45). Quantitative analysis considered the properties of a newly developed rating scale in sample 1, in an additional sample of patients with mood disorders (sample 2, n = 37) and in healthy subjects (sample 3, n = 38). RESULTS Qualitative analysis of individual interviews revealed that 5 conceptual categories characterized thought overactivation: sequential thought flow, overstimulation, competition for resource allocation, unexpected/unexplained onset, and association with mood and emotions. A principal component analysis of the initial 16-item rating scale indicated that a single component explained 55.9% of the variance, with major and exclusive contributions from 9 items, which were retained in the final 9-item Subjective Thought Overactivation Questionnaire (STOQ; Cronbach's α = 0.95). Total score correlated significantly with activation, depression and perceived conflict subscales of the Internal State Scale (ISS; rs = 0.57-0.66, p < 0.001). It was associated with decreased well-being (ISS; rs = -0.48, p = 0.001) and increased state anxiety (State-Trait Anxiety Inventory; rs = 0.60, p < 0.001). The STOQ score was significantly higher in patients than in healthy subjects. It allowed distinguishing between ISS mood states, with the highest median score in mixed states. LIMITATIONS Sample size, representativeness, possible bias in qualitative analysis, and quality of expert consensus. CONCLUSIONS Qualitative analysis of clinical interviews, together with a new short rating scale, contributed to a documentation of subjective thought overactivation, an important but often undetected feature in mood disorders.

Abstract
BACKGROUND Mixed depression is a common, dimensional phenomenon that is increasingly recognized in unipolar and bipolar disorders. We piloted a modified version of the Hypomania Checklist (mHCL-32) to assess the prevalence and clinical correlates of concurrent manic (hypo) symptoms in depressed patients. METHODS The mHCL-32, Young Mania Rating Scale (YMRS) and Hamilton Rating Scale for Depression (HAMD-24) were utilized in the assessment of unipolar (UP=61) and bipolar (BP=44) patients with an index major depressive episode confirmed by the Structured Clinical Interview for DSM-IV (SCID). Differential mHLC-32 item endorsement was compared between UP and BP. Correlation analyses assessed the association of symptom dimensions measured by mHCL-32, YMRS and HAMD-24. RESULTS There was no significant difference between mood groups in the mean mHCL-32 and YMRS scores. Individual mHLC-32 items of increased libido, quarrels, and caffeine intake were endorsed more in BP vs. UP patients. The mHCL-32 active-elevated subscale score was positively correlated with the YMRS in BP patients and negatively correlated with HAMD-24 in UP patients. Conversely, the mHCL-32 irritable-risk taking subscale score was positively correlated with HAMD-24 in BP and with YMRS in UP patients. LIMITATIONS Small sample size and cross-sectional design. CONCLUSION Modifying the HCL to screen for (hypo) manic symptoms in major depression may have utility in identifying mixed symptoms in both bipolar vs. unipolar depression. Further research is encouraged to quantify mixed symptoms with standardized assessments.

Abstract
The definitions of bipolar-I (BP-I) and bipolar-II (BP-II) disorders are currently under revision by the APA and by the WHO. We provide evidence of a revised set of criteria for bipolar disorders and major depressive disorder (MDD) which could serve to strengthen the construct and predictive validity of both disorders and enable more incisive studies of treatments and courses of both disorders. In the diagnostic Bridge Study of 5,635 patients with major depressive episodes from 18 countries (Europe, North Africa, Near East and Far East) leading psychiatrists in each country assessed a pre-specified group of symptoms, illness course, family history and duration of episodes; these data allowed tests of several definitions of bipolarity. The primary revised specifier diagnosis of BP-I disorder included manic episodes based on an additional category A criterion (increased activity/energy) and did not apply any exclusion criteria. The revised BP-II disorders included hypomanic episodes of 1-3 days. Family history and illness course validators (history of mania/hypomania among first degree relatives, 2 or more lifetime episodes and first symptoms having occurred before age 30) discriminated clearly between patients with bipolar-I or bipolar-II disorders meeting bipolarity specifier criteria and those with MDD. Specifier definitions provided better discrimination between MDD and the two bipolar subgroups. Patterns of concurrent comorbidities also differed significantly between patients meeting criteria for MDD compared with those meeting bipolar specifier criteria. Comorbidity patterns differed between bipolar-I and bipolar-II patients. This study provides evidence for the validity of modified (specifier) BP-I and BP-II definitions that incorporate illness course and family history which reduce ambiguities of major depressive episodes between bipolar-I and bipolar-II disorders and MDD.

Abstract
The treatment of bipolar depression is still an important challenge for clinicians and the number of evidence based options is limited. Antidepressants are the most frequently prescribed drugs for bipolar depression in clinical practice, even though the relative risks and benefits of using this treatment strategy has been strongly debated over the past 25 years. One of the reasons is that several placebo-controlled studies have shown that antidepressants could induce manic or hypomanic episodes and accelerate the rate of cycling, worsening the course of the illness by increasing the number of mood episodes over time. Antidepressant-Induced Manias (AIM) have been reported in a subgroup of about 25 to 30% of bipolar patients. There is an increased risk of mood switch with tricyclic antidepressants (TCAs) and serotonin and noradrenaline reuptake inhibitors (SNRIs). The occurrence of mania during antidepressant treatment is a crucial issue in the clinical management of Bipolar Disorder (BD) since it greatly interferes with the establishment of an optimal treatment for bipolar depression. It can have substantial negative impact on overall mood and psychosocial stability in patients receiving treatment for bipolar depression, possibly leading to treatment resistance. Therefore, the identification of clinical correlates associated with AIM is essential to better identify at-risk subgroups of patients and propose specific individualized treatment strategies for bipolar depression. No risk factors has been replicated so far, mostly because studies are characterized by small sample sizes and by the absence of a consensus definition of AIM, showing conflicting results. In this study, patients were classified according to a restrictive definition, similar to that used by Rousseva et al. (2003). An AIM− group (n = 135) was compared to AIM+ patients (n = 75) for clinical and sociodemographic factors as well as for psychological dimensions.

Abstract
OBJECTIVE The risk-benefit profile of antidepressant medications in bipolar disorder is controversial. When conclusive evidence is lacking, expert consensus can guide treatment decisions. The International Society for Bipolar Disorders (ISBD) convened a task force to seek consensus recommendations on the use of antidepressants in bipolar disorders. METHOD An expert task force iteratively developed consensus through serial consensus-based revisions using the Delphi method. Initial survey items were based on systematic review of the literature. Subsequent surveys included new or reworded items and items that needed to be rerated. This process resulted in the final ISBD Task Force clinical recommendations on antidepressant use in bipolar disorder. RESULTS There is striking incongruity between the wide use of and the weak evidence base for the efficacy and safety of antidepressant drugs in bipolar disorder. Few well-designed, long-term trials of prophylactic benefits have been conducted, and there is insufficient evidence for treatment benefits with antidepressants combined with mood stabilizers. A major concern is the risk for mood switch to hypomania, mania, and mixed states. Integrating the evidence and the experience of the task force members, a consensus was reached on 12 statements on the use of antidepressants in bipolar disorder. CONCLUSIONS Because of limited data, the task force could not make broad statements endorsing antidepressant use but acknowledged that individual bipolar patients may benefit from antidepressants. Regarding safety, serotonin reuptake inhibitors and bupropion may have lower rates of manic switch than tricyclic and tetracyclic antidepressants and norepinephrine-serotonin reuptake inhibitors. The frequency and severity of antidepressant-associated mood elevations appear to be greater in bipolar I than bipolar II disorder. Hence, in bipolar I patients antidepressants should be prescribed only as an adjunct to mood-stabilizing medications.

Paterniti S, Bisserbe JC. Pharmacotherapy for bipolar disorder and concordance with treatment guidelines: survey of a general population sample referred to a tertiary care service. BMC Psychiatry 2013; 13:211.

Abstract
BACKGROUND Many new approaches have been adopted for the treatment of bipolar disorder (BD) in the past few years, which strived to produce more positive outcomes. To enhance the quality of care, several guideline recommendations have been developed. For study purposes, we monitored the prescription of psychotropic drugs administered to bipolar patients who had been referred to tertiary care services, and assessed the degree to which treatment met specific guidelines. METHODS Between December 2006 and February 2009, we assessed 113 individuals suffering from BD who had been referred to the Royal Ottawa Mental Health Centre (ROMHC) Mood Disorders Program by physicians within the community, mostly general practitioners. The Structured Clinical Interview for DSM-IV-TR was used to assess diagnosis. The prescribed treatment was compared with specific Canadian guidelines (CANMAT, 2009). Univariate analyses and logistic regression were used to assess the contribution of demographic and clinical factors for concordance of treatment with guidelines. RESULTS Thirty-two subjects had BD type I (BD-I), and 81 subjects had BD type II (BD-II). All subjects with BD-I, and 90% of the BD-II group were given at least one psychotropic treatment. Lithium was more often prescribed for subjects with BD-I (62%) than those with BD-II (19%). Antidepressants were the most frequently prescribed class of psychotropics. Sixty-eight percent of subjects received treatment concordant with guidelines by medication and dose. The presence of a current hypomanic episode was independently associated with poorer concordance to guidelines. In more than half the cases, the inappropriate use of antidepressants was at the origin of the non concordance of treatment with respect to guidelines. Absence of psychotropic treatment in bipolar II patients and inadequate dosage of mood stabilizers were the two other main causes of non concordance with guidelines. CONCLUSIONS The factors related to treatment not concordant with guidelines should be further explored to determine appropriate strategies in implementing the use of guidelines in clinical practice.

Abstract
Chronotherapeutics refers to treatments based on the principles of circadian rhythm organization and sleep physiology, which control the exposure to environmental stimuli that act on biological rhythms, in order to achieve therapeutic effects in the treatment of psychiatric conditions. It includes manipulations of the sleep-wake cycle such as sleep deprivation and sleep phase advance, and controlled exposure to light and dark. The antidepressant effects of chronotherapeutics are evident in difficult-to-treat conditions such as bipolar depression, which has been associated with extremely low success rates of antidepressant drugs in naturalistic settings and with stable antidepressant response to chronotherapeutics in more than half of the patients. Recent advances in the study of the effects of chronotherapeutics on neurotransmitter systems, and on the biological clock machinery, allow us to pinpoint its mechanism of action and to transform it from a neglected or “orphan” treatment to a powerful clinical instrument in everyday psychiatric practice.

Abstract
Depressive symptoms and episodes dominate the long-term course of bipolar disorder and are associated with high levels of disability and an increased risk of suicide. However, the treatment of bipolar depression has been poorly investigated in comparison with that of manic episodes and unipolar major depressive disorder. The goal of treatment in bipolar depression is not only to achieve full remission of acute symptoms, but also to avoid long-term mood destabilization and to prevent relapses. A depressive presentation of bipolar disorder may often delay the appropriate management and, thus, worsen the long-term outcome. In these cases, an accurate screening for diagnostic indicators of a possible bipolar course of the illness should guide the therapeutic choices, and lead to prognostic improvement. Antidepressant use is still the most controversial issue in the treatment of bipolar depression. Despite inconclusive evidence of efficacy and tolerability, this class of agents is commonly prescribed in acute and long-term treatment, often in combination with mood stabilizers. In this article, we review available treatment options for bipolar depression, and we shall provide some suggestions for the management of the different presentations of depression in the course of bipolar disorder.

Abstract
Bipolar depression remains a major unresolved challenge for psychiatric therapeutics. It is associated with significant disability and mortality and represents the major proportion of the approximately half of follow-up time spent in morbid states despite use of available treatments. Evidence regarding effectiveness of standard treatments, particularly with antidepressants, remains limited and inconsistent. We reviewed available clinical and research literature concerning treatment with antidepressants in bipolar depression and its comparison with unipolar depression. Research evidence concerning efficacy and safety of commonly used antidepressant treatments for acute bipolar depression is very limited. Nevertheless, an updated meta-analysis indicated that overall efficacy was significantly greater with antidepressants than with placebo-treatment and not less than was found in trials for unipolar major depression. Moreover, risks of non-spontaneous mood-switching specifically associated with antidepressant treatment are less than appears to be widely believed. The findings encourage additional efforts to test antidepressants adequately in bipolar depression, and to consider options for depression in types I vs. II bipolar disorder, depression with subsyndromal hypomania and optimal treatment of mixed agitated-dysphoric states--both short- and long-term. Many therapeutic trials considered were small, varied in design, often involved co-treatments, or lacked adequate controls.

Abstract
OBJECTIVE The nature of mixed mood episodes is still a matter of controversy amongst experts. Currently, the approach to this syndrome is mainly categorical and very restrictive. The factor-structure of bipolar mood episodes has not been studied yet. We performed a dimensional analysis of the structure of bipolar episodes aimed at identifying a factor deconstructing mixed episodes; furthermore, we analyzed correlations of factors emerging from the factorial analysis of the Brief Psychiatric Rating Scale (BPRS) with Temperament Evaluation of Memphis-Pisa-Paris-San Diego (TEMPS-A) and predominant polarity. METHOD 187 consecutive bipolar I inpatients hospitalized for DSM-IV-TR acute mood episodes (depressive, manic or mixed) underwent a standardized assessment, including the 24-item Brief Psychiatric Rating Scale (BPRS 4.0), the 21-item Hamilton Depression Rating Scale (HDRS-21), the Young Mania Rating Scale (YMRS) and the TEMPS-A. Principal factor analysis was performed on BPRS-24 items. RESULTS This analysis revealed five factors corresponding to "psychosis", "euphoric mania", "mixity", "dysphoria" and "inhibited depression", capturing 71.89% of the rotated variance. The mixity factor was characterized by higher rates of suicidal ideation, more mixed episodes, higher frequencies of antidepressant (AD) use, depressive predominant polarity and anxious temperament. DISCUSSION The factor-structure of the BPRS in inpatients with bipolar I disorder with an acute episode of any type is pentafactorial; one factor identified is the mixity factor, which is independent from other factors and characterized by anxiety and motor hyperactivity and by the absence of motor retardation. Our results should prompt reconsideration of proposals for DSM-5 diagnostic criteria for the mixed features specifier. Limitations of the study include the relative small sample, the absence of drug-naïve patients and the use of rating scales no specific for mixed states.

Abstract
OBJECTIVES These guidelines are based on a first edition that was published in 2004, and have been edited and updated with the available scientific evidence up to October 2012. Their purpose is to supply a systematic overview of all scientific evidence pertaining to the long-term treatment of bipolar disorder in adults. METHODS Material used for these guidelines are based on a systematic literature search using various data bases. Their scientific rigor was categorised into six levels of evidence (A-F) and different grades of recommendation to ensure practicability were assigned. RESULTS Maintenance trial designs are complex and changed fundamentally over time; thus, it is not possible to give an overall recommendation for long-term treatment. Different scenarios have to be examined separately: Prevention of mania, depression, or an episode of any polarity, both in acute responders and in patients treated de novo. Treatment might differ in Bipolar II patients or Rapid cyclers, as well as in special subpopulations. We identified several medications preventive against new manic episodes, whereas the current state of research into the prevention of new depressive episodes is less satisfactory. Lithium continues to be the substance with the broadest base of evidence across treatment scenarios. CONCLUSIONS Although major advances have been made since the first edition of this guideline in 2004, there are still areas of uncertainty, especially the prevention of depressive episodes and optimal long-term treatment of Bipolar II patients.

Abstract
BACKGROUND Bipolar disorder (BD) is a recurrent and disabling illness, characterized by periods of depression and mania. The history of the illness differs widely between patients, with episode frequency emerging as a strong predictor of poor illness outcome. Lithium salts are the first-choice long-term mood-stabilizing therapy, but not all patients respond equally to the treatment. Evidence suggests that alterations in glutamatergic systems may contribute to the pathophysiology of depression. Moreover, glutamate signaling is involved in brain development and synaptic plasticity, both of which are modified in individuals affected by BD, and has been implicated in the etiology of the disorder. The inactivation of glutamate is handled by a series of molecular glutamate transporters (excitatory amino acid transporters [EAATs]), among which EAAT2/SLC1A2 is responsible for up to 95% of extracellular glutamate clearance. A functional single-nucleotide polymorphism at -181 bp from the transcription start site of the SLC1A2 gene has been described. This T-to-G (DNA forward strand) polymorphism, commonly known as SLC1A2 -181A>C, affects transporter expression, with the variant G allele inducing a 30% reduction in promoter activity compared with the T allele. OBJECTIVE The aims of the study were to investigate if factors affecting glutamate function, such as SLC1A2 -181A>C (rs4354668), could affect recurrence of illness in BD, and if they interact with lithium salt treatment. METHODS We performed an observational study in our university hospital in Milan. We enrolled 110 subjects (76 females, 34 males) affected by BD type I. The exclusion criteria were other diagnoses on Axis I, mental retardation on Axis II, a history of epilepsy, and major medical and neurologic disorders. Fifty-four patients had been treated with lithium salts for more than 6 months. Patients were genotyped for SLC1A2 -181A>C by polymerase chain reaction-restriction fragment length polymorphism, and the influence of genotype on BD episode recurrence rates, and the interaction between the single nucleotide polymorphism and lithium treatment, were analyzed. RESULTS The SLC1A2 -181A>C genotype significantly influenced the total recurrence of episodes, with T/T homozygotes showing a significantly lower frequency of episodes (F = 3.26; p = 0.042), and an interaction between lithium treatment and genotype (F = 3.77; p = 0.026) was found to influence the history of the illness. CONCLUSION According to our results, the glutamatergic system could be hypothesized to exert some influence on the history of illness in BD. The SLC1A2 functional polymorphism was shown to significantly influence the total episode recurrence rate, with wild-type T homozygotes presenting the lowest number of episodes, G homozygotes reporting the highest number, and heterozygotes showing an intermediate phenotype. We confirmed the efficacy of lithium treatment in reducing the recurrence of illness in BD, and we found an interaction between lithium treatment and the SLC1A2 -181A>C genotype, confirming previous studies reporting an interaction between lithium salts and the glutamatergic system.

Abstract
INTRODUCTION The treatment of depressive episodes in bipolar disorder (BD) remains a challenge for clinicians and is a hot topic in current psychiatric practice. In the present review, we focused on efficacy and safety of fluoxetine monotherapy in order to identify published randomized double-blind trials and open-label trials, written in English, reporting the outcome of fluoxetine treatment in depressed bipolar patients. AREAS COVERED We searched Pubmed to identify published randomized double-blind trials and open-label trials, written in English, reporting the results of fluoxetine treatment in depressed bipolar patients. The following key words were used: fluoxetine AND bipolar AND depression AND treatment. A total number of seven prospective studies (four randomized clinical trials and three open-label trials) and one two-phase retrospective study were reviewed. EXPERT OPINION Fluoxetine showed to be efficacious in bipolar depression, confirming its well-known activity in major depressive episodes, with a low percentage of mood switch, despite the general view that antidepressants may increase the rate of manic/hypomanic episodes in BDs. More studies with larger sample sizes, comparing fluoxetine with other antidepressants, mood stabilizers and antipsychotics are needed.

Abstract
BACKGROUND Pattern analysis can aid understanding of trajectories of symptom evolution. However, most studies focus on relatively homogeneous disorders with a restricted range of outcomes, prescribed a limited number of classes of medication. We explored the utility of pattern analysis in defining short-term outcomes in a heterogeneous clinical sample with acute bipolar disorders. METHOD In a naturalistic observational study, we used Group-based trajectory modeling (GBTM) to define trajectories of symptom change in 118 bipolar cases recruited during an acute DSM IV episode: major depression (56%), (hypo)mania (26%), and mixed states (18%). Symptoms were assessed weekly for a month using the MATHYS, which measures symptoms independent of episode polarity. RESULTS Four trajectories of symptom change were identified: Persistent Inhibition, Transient Inhibition, Transient Activation and Over-activation. However, counter to traditional predictions, we observed that bipolar depression shows a heterogeneous response pattern with cases being distributed approximately equally across trajectories that commenced with inhibition and activation. LIMITATIONS The observational period focuses on acute outcomes and so we cannot use the findings to predict whether the trajectories lead to stable improvement or whether the clinical course for some clusters is cyclical. As in all GBTM, the terms used for each trajectory are subjective, also the modeling programme we used assumes dropouts are random, which is clearly not always the case. CONCLUSION This paper highlights the potential importance of techniques such as GBTM in distinguishing the different response trajectories for acutely ill bipolar cases. The use of the MATHYS provides further critical insights, demonstrating that clustering of cases with similar response patterns may be independent of episodes defined by mood state.

Abstract
INTRODUCTION Electronic self-monitoring of affective symptoms using cell phones is suggested as a practical and inexpensive way to monitor illness activity and identify early signs of affective symptoms. It has never been tested in a randomised clinical trial whether electronic self-monitoring improves outcomes in bipolar disorder. We are conducting a trial testing the effect of using a Smartphone for self-monitoring in bipolar disorder. METHODS We developed the MONARCA application for Android-based Smartphones, allowing patients suffering from bipolar disorder to do daily self-monitoring-including an interactive feedback loop between patients and clinicians through a web-based interface. The effect of the application was tested in a parallel-group, single-blind randomised controlled trial so far including 78 patients suffering from bipolar disorder in the age group 18-60 years who were given the use of a Smartphone with the MONARCA application (intervention group) or to the use of a cell phone without the application (placebo group) during a 6-month study period. The study was carried out from September 2011. The outcomes were changes in affective symptoms (primary), social functioning, perceived stress, self-rated depressive and manic symptoms, quality of life, adherence to medication, stress and cognitive functioning (secondary and tertiary). ANALYSIS Recruitment is ongoing. ETHICS Ethical permission has been obtained. DISSEMINATION Positive, neutral and negative findings of the study will be published. REGISTRATION DETAILS The trial is approved by the Regional Ethics Committee in The Capital Region of Denmark (H-2-2011-056) and The Danish Data Protection Agency (2013-41-1710). The trial is registered at ClinicalTrials.gov as NCT01446406.

Add-on Lamotrigine Treatment for Subsyndromal Depression after Manic or Mixed States in Bipolar Disorder Improved the Quality of Life. Case Rep Med 2012; 2012:736521.

Abstract
Two cases of patients experienced subsyndromal depression after manic or mixed hypomanic and depressive episodes due to bipolar I (case 1) and II (case 2) disorders prior to the use of lamotrigine. Case 1 showed episodes of mood switching induced by antidepressants and seasonal mood instability. Case 2 showed hippocampal atrophy and a persistent dull headache that preceded the use of lamotrigine. Both were successfully treated with add-on lamotrigine therapy, and the dull headache was effectively treated with olanzapine. Both patients improved in social activity and work performance after these add-on treatments. Thus, add-on treatment with lamotrigine alone or in combination with olanzapine was an effective strategy to improve the quality of life in bipolar depression. Subsyndromal depression that present after the disappearance of the manic or mixed state was suggested to be practical indication for the use of lamotrigine.

Abstract
OBJECTIVE Several treatment guidelines are available for clinicians working with patients with bipolar disorder (BD), but some of the more nuanced aspects of lithium therapy go beyond the scope of such guidelines. Therefore, in this perspective, our objective was to focus on specific practical issues of lithium treatment, including the selection and initiation of long-term treatment, and management and discontinuation (if indicated) of lithium prophylaxis. METHOD We conducted a focused review of the relevant literature on the treatment of BD. RESULTS Consultation requests to a BD specialty service often relate to issues for which there is limited evidence, including when to initiate long-term treatment, whether choice of mood stabilizer is specific, how long to treat acute episodes, whether to switch or add on medication when treatment fails, how long to continue effective treatment, and what medication to use when a lithium-responsive patient must discontinue lithium. CONCLUSION Optimal long-term treatment of BD will require more research as well as better alignment of clinical and training programs.

Abstract
BACKGROUND Assessment of emotional reactivity, defined as rapid emotional responses to salient environmental events, has been neglected in mood disorders. This article reviews data showing the relevance of using emotional reactivity to better characterize bipolar mood episodes. METHOD We reviewed clinical data on emotional reactivity during all phases of bipolar disorders (euthymic, manic, mixed and depressive states) and brain-imaging, neurochemical, genetic studies related to emotional reactivity disturbances. RESULT Euthymic bipolar patients show mild abnormalities (hypersensitivity to emotional stimuli and higher arousability) in comparison to controls. Both manic and mixed states are characterized by a significant increase in emotional reactivity. Furthermore, emotional reactivity may discriminate between two types of bipolar depression, the first being characterized by emotional hypo-reactivity and global behavioral inhibition, the second by emotional hyper-reactivity. Brain-imaging studies can help to identify the underlying mechanisms involved in disturbances of emotional reactivity. CONCLUSION Emotional reactivity can be used to refine more homogeneous pathophysiological subtypes of mood episodes. Future research should explore possible correlations between biomarkers, response to treatments and these clinical phenotypes.

Abstract
BACKGROUND There is increasing evidence that subsyndromal manic symptoms occur frequently during bipolar major depressive episodes (MDEs) and may be a subtle form of 'depressive mixed state.' This paper examines the prevalence and clinical characteristics of MDEs with subsyndromal manic symptoms. The specific effects of overt irritability and psychomotor agitation are examined. METHODS Bipolar (type I or II) patients with an MDE at intake (N=142) were compared based on the presence or absence of concurrent subsyndromal manic symptoms. The groups were further subdivided by the presence of symptoms of overt irritability and/or psychomotor agitation. RESULTS Subsyndromal manic symptoms during bipolar MDEs were highly prevalent (76.1%), and were associated with significantly increased severity of depression/dysphoria in the intake episode, longer episode duration, and more suicidal ideation and behavior (past, current, and during long-term follow-up). Overt irritability and psychomotor agitation were the most prevalent subsyndromal manic symptoms (co-occurring in 57% and 39% of MDEs, respectively), and accounted for most of the negative effects associated with subsyndromal manic symptoms. LIMITATIONS The findings need to be confirmed in larger samples, which also examine the relationship to adequate antidepressant and/or mood stabilizing treatment. CONCLUSIONS The presence of one or more subsyndromal manic symptoms appears to be the modal presentation of bipolar MDEs and a marker for a subtle form of bipolar mixed depressive state. In particular, patients with symptoms of overt irritability and/or psychomotor agitation should be monitored closely to avoid serious clinical outcomes such as longer affective episodes, exacerbation of manic symptoms syndromal mania, and heightened suicidality.

Abstract
OBJECTIVE To review the efficacy of pharmacological agents in bipolar mixed states. METHODS We conducted a PubMed search of all English-language articles involving Food and Drug Administration (FDA)-approved agents for manic/mixed states in adults with bipolar I disorder. We also included names of agents established as efficacious in acute mania/mixed states that have not received FDA approval for bipolar disorder. Bibliographies from relevant articles were also searched. The efficacy of each agent in the mixed state subpopulation was reviewed, as evidenced by change from baseline on total scores of mania [e.g., Young Mania Rating Scale (YMRS)] and depression [e.g., Montgomery-Åsberg Depression Rating Scale (MADRS)] measures. RESULTS No available study is dedicated exclusively to the evaluation of mixed state populations. Although key inclusion and exclusion criteria are similar across treatment studies, mixed states have been variably defined and measured. The use of conventional manic and depressive metrics in bipolar mixed states perpetuates the unproven notion that mixed states are the consequence of coexisting depression and mania. Notwithstanding the methodological limitations, there are numerically more studies that exist for atypical antipsychotic agents than for any other class. On the basis of symptomatic improvement, recommendations for and/or strong admonishments against any established antimanic agents (e.g., lithium) cannot be made. An emergent signal supports combination treatment strategies (e.g., atypical antipsychotic plus divalproex) over mood stabilizer monotherapy (e.g., divalproex). Available evidence does not empirically support the hypothesis that conventional antipsychotics engender and/or amplify depressive symptoms in bipolar mixed states. CONCLUSIONS All proven antimanic agents (including lithium), can be recommended in the treatment of mixed/dysphoric states. The totality of evidence with attention paid to the therapeutic index of each agent would suggest that atypical antipsychotics and divalproex be considered as first-line treatment, with lithium and carbamazepine as second-line. Most individuals will require combination therapy for the treatment of mixed states; variable combinations of atypical antipsychotics and conventional mood stabilizers have the most replicated evidence.

Abstract
Treatment of bipolar disorder often results in patients taking several drugs in an attempt to alleviate residual depressive symptoms, which can lead to an accumulation of side effects. New treatments for bipolar depression that do not increase the side effect burden are needed. One nonpharmacological treatment with few side effects, bright light therapy, has been shown to be an effective therapy for seasonal affective disorder, yet has not been extensively studied for other forms of depression. Forty-four adults with bipolar disorder, depressed phase were randomized to treatment with bright light therapy, low-density or high-density negative ion generator for 8 weeks. The primary measure of efficacy was the Structured Interview Guide for the Hamilton Depression Rating Scale with Atypical Depression Supplement (SIGH-ADS). Adverse events were assessed using the Young Mania Rating Scale (YMRS) and Systematic Assessment for Treatment Emergent effects (SAFTEE). All outcome variables were statistically analyzed using a mixed model repeated measure analysis of variance (ANOVA). The results showed no statistically significant differences between groups in any outcome measures at study end point; adverse events, including switches into hypomania, were rare. Further research is needed to determine the efficacy of bright light therapy in this population.

Abstract
The Systematic Treatment Enhancement Program for Bipolar Disorder (STEP-BD) was funded as part of a National Institute of Mental Health initiative to develop effectiveness information about treatments, illness course, and assessment strategies for severe mental disorders. STEP-BD studies were planned to be generalizable both to the research knowledge base for bipolar disorder and to clinical care of bipolar patients. Several novel methodologies were developed to aid in illness characterization, and were combined with existing scales on function, quality of life, illness burden, adherence, adverse effects, and temperament to yield a comprehensive data set. The methods integrated naturalistic treatment and randomized clinical trials, which a portion of STEP-BD participants participated. All investigators and other researchers in this multisite program were trained in a collaborative care model with the objective of retaining a high percentage of enrollees for several years. Articles from STEP-BD have yielded evidence on risk factors impacting outcomes, suicidality, functional status, recovery, relapse, and caretaker burden. The findings from these studies brought into question the widely practiced use of antidepressants in bipolar depression as well as substantiated the poorly responsive course of bipolar depression despite use of combination strategies. In particular, large studies on the characteristics and course of bipolar depression (the more pervasive pole of the illness), and the outcomes of treatments concluded that adjunctive psychosocial treatments but not adjunctive antidepressants yielded outcomes superior to those achieved with mood stabilizers alone. The majority of patients with bipolar depression concurrently had clinically significant manic symptoms. Anxiety, smoking, and early age of bipolar onset were each associated with increased illness burden. STEP-BD has established procedures that are relevant to future collaborative research programs aimed at the systematic study of the complex, intrinsically important elements of bipolar disorders.

Abstract
After a series of serendipitous discoveries of pharmacological treatments for mania and depression several decades ago, relatively little progress has been made for novel hypothesis-driven drug development in mood disorders. Multifactorial etiologies of, and lack of a full understanding of, the core neurobiology of these conditions clearly have contributed to these development challenges. There are, however, relatively novel targets that have raised opportunities for progress in the field, such as glutamate and cholinergic receptor modulators, circadian regulators, and enzyme inhibitors, for alternative treatment. This review will discuss these promising new treatments in mood disorders, the underlying mechanisms of action, and critical issues of their clinical application. For these new treatments to be successful in clinical practice, it is also important to design innovative clinical trials that identify the specific actions of new drugs, and, ideally, to develop biomarkers for monitoring individualized treatment response. It is predicted that future drug development will identify new agents targeting the molecular mechanisms involved in the pathophysiology of mood disorders.

Abstract
BACKGROUND Subsyndromal symptoms have been recognized as relevant in the course and outcome of bipolar disorder (BD) patients. Nevertheless, their definition and cutoff points on current depression and mania scales are uncertain. The recently defined International Society for Bipolar Disorders (ISBD) operational criteria for the assessment of the course and outcome of bipolar illness have never been tested until now. METHODS A naturalistic longitudinal follow-up study of up to 5 years included a cohort of 317 DSM-IV-TR BD outpatients. For the first time, we assessed the proportion of visits in different affective states using the ISBD criteria. Secondarily, we compared the results with those obtained applying other cutoff points. RESULTS Patients were symptomatic in 39.1% (95% CI 35.3-42.9) of the visits. Subsyndromal symptoms, primarily subsyndromal depression, were present in 15.9% of patients (95% CI 13.4-18.4). No significant differences were found between bipolar I patients and bipolar II patients. There were differences in the total percentage of visits in euthymia depending on the cutoff points (p < 0.05). CONCLUSIONS Applying ISBD criteria, bipolar patients have significant clinical morbidity and are often symptomatic, both with threshold symptoms and with subthreshold symptoms, especially with depression. The chosen cutoff points modify the apparent results. LIMITATIONS The cutoff points used have not been validated. Psychopharmacologic treatments were naturalistic.

Abstract
BACKGROUND Antidepressants can trigger a rapid mood switch from depression to mania. Identifying genetic risk factors associated with antidepressant induced mania (AIM) may enable individualized treatment strategies for bipolar depression. This review and meta-analysis evaluates the evidence for association between the serotonin transporter gene promoter polymorphism (5HTTLPR) and AIM. METHODS Medline up to November 2009 was searched for key words bipolar, antidepressant, serotonin transporter, SLC6A4, switch, and mania. RESULTS Five studies have evaluated the SLC6A4 promoter polymorphism and AIM in adults (total N=340 AIM+ cases, N=543 AIM- controls). Although a random effects meta-analysis showed weak evidence of association of the S allele with AIM+ status, a test of heterogeneity indicated significant differences in estimated genetic effects between studies. A similar weak association was observed in a meta-analysis based on a subset of three studies that excluded patients on mood stabilizers; however the result was again not statistically significant. LIMITATIONS Few pharmacogenomic studies of antidepressant treatment of bipolar disorder have been published. The completed studies were underpowered and often lacked important phenotypic information regarding potential confounders such as concurrent use of mood stabilizers or rapid cycling. CONCLUSIONS There is insufficient published data to confirm an association between 5HTTLPR and antidepressant induced mania. Pharmacogenomic studies of antidepressant induced mania have high potential clinical impact provided future studies are of adequate sample size and include rigorously assessed patient characteristics (e.g. ancestry, rapid cycling, concurrent mood stabilization, and length of antidepressant exposure).

Abstract
Growing clinical evidence in support of the efficacy and safety of sleep deprivation (SD), and its biological mechanisms of action suggest that this technique can now be included among the first-line antidepressant treatment strategies for mood disorders. SD targets the broadly defined depressive syndrome, and can be administered according to several different treatment schedules: total versus partial, single versus repeated, alone or combined with antidepressant drugs, mood stabilizers, or other chronotherapeutic techniques, such as light therapy and sleep phase advance. The present review focuses on clinical evidence about the place of SD in therapy, its indications, dosage and timing of the therapeutic wake, interactions with other treatments, precautions and contraindications, adverse reactions, mechanism of action, and comparative efficacy, with the aim of providing the clinical psychiatrist with an updated, concise guide to its application.

Abstract
OBJECTIVE To examine the longitudinal course of pediatric bipolar (BP)-I disorder in youth transitioning from childhood into adolescence. METHODS We conducted a four year prospective follow-up study of 78 youth with BP-I disorder 6-17 years old at ascertainment followed up into adolescent years (13.4 ± 3.9 years). All subjects were comprehensively assessed with structured diagnostic interviews, neuropsychological testing, psychosocial, educational and treatment history assessments. BP disorder was considered persistent if subjects met full criteria for DSM-IV BP-I disorder at follow-up. RESULTS Of 78 BP-I participating youth subjects, 57 (73.1%), continued to meet full diagnostic criteria for BP-I Disorder. Of those with a non-persistent course, only 6.4% (n = 5) were euthymic (i.e., syndromatic and symptomatic remission) at the 4-year follow-up and were not receiving pharmacotherapy for the disorder. The other non-persistent cases either continued to have subthreshold BP-I disorder (n = 5, 6.4%), met full (n = 3, 3.8%) or subthreshold (n = 1, 1.3%) criteria for major depression, or were euthymic but were treated for the disorder (n = 7, 9.0%). Full persistence was associated with higher rates of major depression and disruptive behavior disorders at the follow-up assessment and higher use of stimulant medicines at the baseline assessment. Non-Peristent BP-I was also characterized by high levels of dysfunction and morbidity. CONCLUSIONS This four year follow-up shows that the majority of BP-I disorder youth continue to experience persistent disorder into their mid and late adolescent years and its persistence is associated with high levels of morbidity and disability. Persistence of subsyndromal forms of bipolar disorder was also associated with dysfunction and morbidity.

Abstract
OBJECTIVE Current criteria for mixed bipolar episode do not allow an adequate understanding of a vast majority of bipolar patients with mixed (hypo) manic-depressive features, keeping the qualification of "mixed episodes" for bipolar type I only. This study was aimed to test the existence of a bipolar-mixed continuum by comparing the characteristics of three groups classified according to patterns of past and current manic or mixed episodes. METHOD 134 bipolar I inpatients were divided according to their pattern of excitatory "mixed-like" episodes in three groups: 1) lifetime history of purely manic episodes without mixed features (PMA); 2) lifetime history of both manic and mixed episodes (MIX) and 3) lifetime history exclusively of mixed, but not manic, episodes (PMIX). Differences in clinical and demographic characteristics were analyzed by using chi-square head-to-head for categorical data, one-way ANOVA for continuous variables and Tukey's post-hoc comparison. Logistic regression was used to control for data validity. RESULTS PMIX had higher rates of depressive predominant polarity and less lifetime history of psychotic symptoms, and had received more antidepressants both lifetime and during 6 months prior to index episode. PMIX had more suicide attempts and Axis I comorbidity than PMA. DISCUSSION PMIX is likely to have a higher risk for suicide and higher rates of comorbidities; current DSM-IV-TR criteria are not fit for correctly classifying these patients and this may affect treatment appropriateness. The concept of "mixicity" should be extended beyond bipolar I disorder to other bipolar disorder subtypes.

Abstract
BACKGROUND Catechol-O-methyltransferase (COMT) inactivates catecholamines, and a G-A transition in the COMT gene (rs4680) influences the enzyme activity and the interaction between cortical and subcortical dopaminergic neurotransmission. In patients affected by bipolar disorder rs4680 can influence antidepressant response and the propensity to develop psychotic symptoms, with the Met/Met genotype exerting a protective role. The same genotype could influence other dopamine-associated psychopathological features, such as mania. METHODS We genotyped rs4680 in a sample of 163 patients affected by bipolar disorder type I, and assessed the personal history of recurrence of the illness. RESULTS We observed a significant association between homozygosis for the rs4680 COMT low-activity variant and a reduced recurrence of manic, but not depressive, episodes during the course of the illness. CONCLUSIONS We suggest that rs4680 could be an inheritable aspect of the mechanisms of dopamine regulation that influence the individual susceptibility of patients with bipolar disorder to develop manic episodes of illness.

Abstract
OBJECTIVE Although depressive symptoms are preponderant in the course of bipolar (BP) disorders, the treatment of BP depression remains a controversial issue with different clinical approaches available. This review addresses the issues of whether antidepressants (ADs) are effective in treating acute and long-term BP depression, risks linked to ADs and what alternatives to ADs are available. METHODS We searched the MEDLINE databases using the following syntax: [bipolar depression AND unipolar depression AND (antidepressants OR anticonvulsants OR lithium OR antipsychotics OR dopamine-agonists OR psychoeducation OR psychotherapy OR electroconvulsive therapy OR transcranial magnetic stimulation)]. The search included studies published up to 31 May 2009 and conducted on adults. RESULTS In the acute treatment of BP depression ADs are effective with no differences among drug classes. However, neither the switch into (hypo)mania induction rate nor the suicide risk linked to AD use are definitely established. The effectiveness of long-term AD use is limited to highly selected samples of patients with positive acute response. The risk of long-term ADs causing cycle acceleration and rapid cycling induction concerns a subpopulation of patients. Valid alternatives to ADs in treating acute BP depression are quetiapine, an olanzapine-fluoxetine combination, and electroconvulsive therapy for more severe patients. Lamotrigine is effective and safe in preventing depressive relapses. Psychotherapy and psychoeducation represent effective adjunctive treatments. CONCLUSION In the treatment of BP depression there is not a specific effective treatment for all the patients. Interventions should therefore be personalised and the scientific evidence should be adapted to each patient's clinical features.

Abstract
The complex relationship between the use of antidepressants and suicidal behaviour is one of the hottest topics of our contemporary psychiatry. Based on the literature, this paper summarizes the author's view on antidepressant-resistant depression and antidepressant-associated suicidal behaviour. Antidepressant-resistance, antidepressant-induced worsening of depression, antidepressant-associated (hypo)manic switches, mixed depressive episode, and antidepressant-associated suicidality among depressed patients are relatively most frequent in bipolar/bipolar spectrum depression and in children and adolescents. As early age at onset of major depressive episode and mixed depression are powerful clinical markers of bipolarity and the manic component of bipolar disorder (and possible its biological background) shows a declining tendency with age antidepressant-resistance/worsening, antidepressant-induced (hypo)manic switches and "suicide-inducing" potential of antidepressants seem to be related to the underlying bipolarity.

Abstract
OBJECTIVES Mood state heterogeneity in bipolar disorder leads to confusion in diagnosis and therapeutic strategies. Recently, the Systematic Treatment Enhancement Program for Bipolar Disorder (STEP-BD) showed that two-thirds of bipolar-depressed patients had concomitant manic symptoms, these characteristics being linked to a more severe form of bipolar disorder. Moreover, manic symptoms occurring during bipolar depression are associated with mood switches induced by antidepressant. It is thus important to best characterize mood episodes with mixed features in order to improve our understanding of the etiopathology and to choose the most appropriate treatment. As dimensional approach can better describe phenomena that are distributed continuously without clear boundaries, we used the MATHYS scale, constructed on a dimensional approach. The aim of the study is to determine whether two dimensions (activation/inhibition and emotional reactivity) improve assessment of bipolar states in which both manic and depressive symptoms are associated. METHODS We included 189 bipolar patients and 90 controls. Bipolar patients were distinguished between those with a major depressive episode without manic symptoms, a major depressive episode with manic symptoms, a mixed state and a manic state. The MATHYS scale provides a total score, quantifying an inhibition/activation process, and a score for emotional reactivity (intensity of emotions). RESULTS We demonstrated that there is a continuum ranging from inhibition to activation (respectively from major depressive episodes without manic symptoms to manic states), with a gradual increase in the severity of the activation. Regarding emotional reactivity, results are quiet different since only major depressive episodes without manic symptoms are characterized by emotional hypo-reactivity while major depressive episodes with manic symptoms, manic and mixed states exhibited emotional hyper-reactivity. CONCLUSIONS The MATHYS scale, providing a score for inhibition/activation process and a score for emotional reactivity, is clearly useful to distinguish bipolar depressive episodes without manic symptoms from those with manic symptoms. This last type of depression appears to belong to a broad spectrum of mixed state. To go further we need to explore if these two types of depression are underlined by different mechanisms and what is the most appropriate treatment for each of them.
