[PMID: 34203943 PMCID: PMC8232811 DOI: 10.3390/medicina57060624] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/07/2021] [Revised: 06/09/2021] [Accepted: 06/11/2021] [Indexed: 02/05/2023]
Abstract
Background and Objectives: Unstable mixed episodes or rapid switching between opposite affective poles within the scope of short cycles was first characterized in 1967 by S. Mentzos as complex polymorphous states with chaotic overlap of manic and depressive symptoms. Well-known examples include antidepressant-induced mania/hypomania and rapid/ultra-rapid/ultradian cycling, when clinicians observe an almost continuous mixed state with a constant change of preponderance of manic or depressive symptoms. Achieving stable remission in these cases is challenging with almost no data on evidence-based treatment. When mood stabilizers are ineffective, electroconvulsive therapy (ECT) has been suggested. Objectives: After reviewing the evidence from available literature, this article presents our own clinical experience of ECT efficacy and tolerability in patients with ultra-rapid cycling bipolar disorder (BD) and unstable mixed states. Materials and Methods: We conducted an open, one-year observational prospective study with a "mirror image" design, including 30 patients with rapid and ultra-rapid cycling BD on long-term mood stabilizer treatment (18 received lithium carbonate, 6 on valproate and 6 on carbamazepine) with limited effectiveness. A bilateral ECT course (5-10 sessions) was prescribed for regaining mood stability. Results: ECT was very effective in 12 patients (40%) with a history of ineffective mood stabilizer treatment who achieved and maintained remission; all of them received lithium except for 1 patient who received carbamazepine and 2 with valproate. Nine patients (30%) showed partial response (one on carbamazepine and two on valproate) and nine patients (30%) had no improvement at all (four on carbamazepine and two on valproate). For the whole sample, the duration of affective episodes was significantly reduced from 36.05 ± 4.32 weeks in the year prior to ECT to 21.74 ± 12.14 weeks in the year post-ECT (p < 0.001). Depressive episodes with mixed and/or catatonic features according to DSM-5 specifiers were associated with a better acute ECT response and/or long-term mood stabilizer treatment outcome after ECT. Conclusions: ECT could be considered as a useful option for getting mood instability under control in rapid and ultra-rapid cycling bipolar patients. Further randomized trials are needed to confirm these results.

Abstract
OBJECTIVES The "Bipolar Disorders: Improving Diagnosis, Guidance, and Education" (BRIDGE-II-Mix) study aimed to estimate the frequency of mixed states in patients with a major depressive episode (MDE) according to different definitions and to compare their clinical validity, looking into specific features such as rapid cycling (RC). METHODS Psychiatric symptoms, socio-demographic, and clinical variables were collected from a sample of 2811 MDE patients, of which 726 (25.8%) were diagnosed with bipolar disorder (BD). The characteristics of bipolar patients with RC (BD-RC) and without (BD-NRC) RC were compared. RESULTS Of 726 BD patients, 159 (21.9%) met DSM-5 criteria for RC. BD-RC group presented a higher number of lifetime depressive episodes (p < 0.001) with shorter duration of depressive episodes, and more psychiatric comorbidities, as well as higher rates of atypical features (p = 0.016) and concomitant (hypo)manic symptoms (irritable mood (p = 0.001); risky behavior (p = 0.005); impulsivity (p = 0.006); and psychomotor agitation (p = 0.029)). Patients with RC had a worse functioning (p = 0.033), more obesity (p = 0.003), and were significantly more likely to be treated with three or more drugs (p = 0.007). CONCLUSIONS Important clinical differences between bipolar patients with and without a RC include more depressive morbidity, higher incidence of anxiety disorders, addiction, bulimia, and borderline personality disorder, as well as atypical features during depression and symptoms such as irritability, risky behavior, impulsivity, and agitation. RC patients had poorer functioning than patients without RC, more obesity, and had to be treated with more drugs.

Abstract
Background Depressive disorders are common among those with bipolar affective disorder (BAD) and may necessitate the use of antidepressants. This has been suggested to precipitate manic episodes in some patients. Objectives This study aims to determine the prevalence of and factors associated with manic switch in patients with BAD being treated with antidepressants. Methods Case notes of patients who were treated at a Nigerian neuropsychiatric hospital for a BAD from 2004 to 2015 were reviewed. BAD diagnosis was made using ICD-10 criteria. Treatment for bipolar depression included monotherapy (i.e. antidepressants, antipsychotics or mood stabilisers) or combination therapy (mood stabiliser with an antidepressant or a combination of mood stabilisers, antipsychotics and antidepressants). The primary outcome measure was a switch to mania or hypomania within 12 weeks of commencing an antidepressant. Results Manic or hypomanic switch (MS) was observed in 109 (44.3%) of the participants. Female gender, younger age, number of previous episodes and a past history of psychiatric hospitalisation were all significantly associated with a risk of MS. There was no significant difference in the rate of MS in either those treated with adjunct antidepressants therapy with a mood stabiliser or an antipsychotic or those placed on a combination of antidepressants, antipsychotics and mood-stabilising agents. Conclusion A large proportion of patients with BAD on antidepressants experience medication-induced manic or hypomanic switch.

Abstract
Background The current paper includes a systematic search of the literature, a detailed presentation of the results, and a grading of treatment options in terms of efficacy and tolerability/safety. Material and Methods The PRISMA method was used in the literature search with the combination of the words 'bipolar,' 'manic,' 'mania,' 'manic depression,' and 'manic depressive' with 'randomized,' and 'algorithms' with 'mania,' 'manic,' 'bipolar,' 'manic-depressive,' or 'manic depression.' Relevant web pages and review articles were also reviewed. Results The current report is based on the analysis of 57 guideline papers and 531 published papers related to RCTs, reviews, posthoc, or meta-analysis papers to March 25, 2016. The specific treatment options for acute mania, mixed episodes, acute bipolar depression, maintenance phase, psychotic and mixed features, anxiety, and rapid cycling were evaluated with regards to efficacy. Existing treatment guidelines were also reviewed. Finally, Tables reflecting efficacy and recommendation levels were created that led to the development of a precise algorithm that still has to prove its feasibility in everyday clinical practice. Conclusions A systematic literature search was conducted on the pharmacological treatment of bipolar disorder to identify all relevant random controlled trials pertaining to all aspects of bipolar disorder and graded the data according to a predetermined method to develop a precise treatment algorithm for management of various phases of bipolar disorder. It is important to note that the some of the recommendations in the treatment algorithm were based on the secondary outcome data from posthoc analyses.

Abstract
OBJECTIVES We examined differences in treatment outcome between Diagnostic and Statistical Manual Fourth Edition (DSM-IV)-defined rapid cycling and average lifetime-defined rapid cycling in subjects with bipolar II disorder. We hypothesized that, compared with the DSM-IV definition, the average lifetime definition of rapid cycling may better identify subjects with a history of more mood lability and a greater likelihood of hypomanic symptom induction during long-term treatment. METHODS Subjects ≥18 years old with a bipolar II major depressive episode (n=129) were categorized into DSM-IV- and average lifetime-defined rapid cycling and prospectively treated with either venlafaxine or lithium monotherapy for 12 weeks. Responders (n=59) received continuation monotherapy for six additional months. RESULTS These exploratory analyses found moderate agreement between the two rapid-cycling definitions (κ=0.56). The lifetime definition captured subjects with more chronic courses of bipolar II depression, whereas the DSM-IV definition captured subjects with more acute symptoms of hypomania. There was no difference between rapid-cycling definitions with respect to the response to acute venlafaxine or lithium monotherapy. However, the lifetime definition was slightly superior to the DSM-IV definition in identifying subjects who went on to experience hypomanic symptoms during continuation therapy. CONCLUSIONS Although sample sizes were limited, the findings suggest that the lifetime definition of rapid cycling may identify individuals with a chronic rapid-cycling course and may also be slightly superior to the DSM-IV definition in identifying individuals with hypomania during relapse-prevention therapy. These findings are preliminary in nature and need replication in larger, prospective, bipolar II studies.

The number of past manic episodes is the best predictor of antidepressant-emergent manic switch in a cohort of bipolar depressed patients. Psychiatry Res 2016; 240:288-294.

Abstract
The present study sought to identify factors associated with the onset of a manic or hypomanic episode during the month following a new antidepressant therapy in depressed bipolar patients. Patients receiving mood stabilizers for ≥3 months were screened from 400 French centers and were assessed for a 4-week period following prescription of a first or a new antidepressant. Of the 1242 included participants, 4.8% (n=60) experienced antidepressant-emergent manic switch (AEMS). AEMS was more frequently associated with lifetime manic, depressive, and total mood episodes, and with past AEMS. A higher score at two items of the Montgomery-Åsberg Depression Rating Scale (pessimistic and suicidal thoughts) were significantly associated with AEMS. Logistic regression analysis showed that the number of lifetime manic episodes and past AEMS were the two most factors associated with an AEMS. Having more than four past manic episodes was associated with a 2.84 fold increased risk of AEMS. Cumulative number of past mood episodes seems to be the most important factor for switching to a manic episode following antidepressants in patients with bipolar disorder. Longer-term studies are required to further delineate antidepressant causality from natural disease course.

Abstract
OBJECTIVE To examine the safety and effectiveness of antidepressant versus mood stabilizer monotherapy in rapid versus non-rapid cycling bipolar II disorder. METHOD Subjects ≥18 years old with bipolar II depression (n = 129) were randomized to double-blind venlafaxine or lithium carbonate monotherapy for 12 weeks. Responders (n = 59) received continuation monotherapy for six additional months. RESULTS Rapid cycling did not affect frequency of response or change over time in depressive symptoms. Rapid cycling status did not affect frequency of depressive relapse or sustained treatment response. Rapid cyclers were more likely to experience hypomanic symptoms (P = 0.005) during continuation monotherapy; however, rates were similar in venlafaxine (17.6%) and lithium (42.9%) (P = 0.31). CONCLUSION Rapid cycling status may not be associated with an increased risk of diminished response or greater depressive relapse during venlafaxine, relative to lithium monotherapy, in bipolar II subjects. Additional randomized studies are needed to confirm these findings.

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
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.

Superior chronic tolerability of adjunctive modafinil compared to pramipexole in treatment-resistant bipolar disorder. J Affect Disord 2013; 150:130-5. [PMID: 23261131 DOI: 10.1016/j.jad.2012.11.030] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/25/2012] [Accepted: 11/07/2012] [Indexed: 01/11/2023]
Abstract
BACKGROUND Suboptimal outcomes are common in bipolar disorder (BD) pharmacotherapy, and may be mitigated with novel adjunctive agents such as modafinil (a low-affinity dopamine transport inhibitor) and pramipexole (a dopamine D2/D3 receptor agonist). While uncontrolled long-term effectiveness data have been reported for these treatments, reports specifically assessing their comparative acute versus chronic tolerability in BD are lacking. Such information, particularly in relation to discontinuation causes, has substantial relevance, providing initial indications to clinicians which treatment may be better tolerated, and to researchers which agent ought to be assessed in longer-term controlled trials. METHODS BD outpatients assessed with the Systematic Treatment Enhancement Program for Bipolar Disorder (STEP-BD) Affective Disorders Evaluation, and followed with the STEP-BD Clinical Monitoring Form, were naturalistically prescribed adjunctive modafinil or pramipexole, and somatic/psychiatric intolerability discontinuation rates were compared. RESULTS Among 63 BD outpatients (mean ± SD age 43.5 ± 14.3 years, 60.3% female, 42.9% type I, 44.4% type II, 12.7% type not otherwise specified), taking 3.5 ± 1.5 (median 3) concurrent prescription psychotropics, adjunctive modafinil (n=24) for 626.9 ± 863.9 (286) days versus pramipexole (n=39) for 473.7 ± 613.4 (214; p=0.51) days yielded a 26.0% lower somatic/psychiatric intolerability discontinuation rate (12.5% vs. 38.5%; p<0.05), with most of the difference accounted for by more pramipexole somatic intolerability discontinuations, due to nausea and sedation, after the first 12 weeks of treatment. LIMITATIONS No placebo comparison group. Small sample of predominantly female Caucasian insured outpatients, taking complex concurrent medication regimens. CONCLUSIONS Further studies are warranted to assess our preliminary observation that modafinil, compared to pramipexole, may be better tolerated for longer-term BD treatment.

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 is considered the most difficult-to-treat phase of bipolar disorder, in relation to its pervasiveness and efficacy and/or tolerability limitations of available treatments. Indeed, most mood stabilizers and atypical antipsychotics are not as effective in ameliorating depressive compared with manic symptoms, and entail substantial tolerability limitations. However, the use of antidepressants is highly controversial, as their efficacy appears less robust in bipolar compared with unipolar depression. In addition, antidepressants, in spite of generally having adequate somatic tolerability, in BD may be associated with a higher risk of manic/hypomanic switch, suicidality and rapid cycling. Among alternative pharmacological strategies, compounds with stimulant and pro-dopaminergic effects, such as methylphenidate, modafinil, armodafinil and pramipexole, have showed potential antidepressant activity, even though their use in clinical practice has been limited by the paucity of controlled evidence. This article seeks to review available evidence about the use of the aforementioned compounds in the treatment of bipolar depression. Findings from reviewed studies suggested that pro-dopaminergic compounds, such as pramipexole and stimulants/stimulant-like agents, deserve consideration as adjunctive therapies in bipolar depressed patients, at least in some subgroups of patients. Nevertheless, caution regarding their use is recommended as further clinical trials with larger samples and longer follow-up periods are necessary to clarify the roles of these medications in bipolar depression.

Abstract
Although the most distinctive clinical feature of bipolar disorder is the pathologically elevated mood, it does not usually constitute the prevalent mood state of bipolar illness. The majority of patients with bipolar disorder spend much more time in depressive episodes, including subsyndromal depressive symptoms, and bipolar depression accounts for the largest part of the morbidity and mortality of the illness. The pharmacological treatment of bipolar depression mostly consists of combinations of at least two drugs, including mood stabilizers (lithium and anticonvulsants), atypical antipsychotics, and antidepressants. Antidepressants are the most frequently prescribed drugs, but recommendations from evidence-based guidelines are not conclusive and do not overtly support their use. Among antidepressants, best evidence exists for fluoxetine, but in combination with olanzapine. Although some guidelines recommend the use of selective serotonin reuptake inhibitors or bupropion in combination with antimanic agents as first-choice treatment, others do not, based on the available evidence. Among anticonvulsants, the use of lamotrigine is overall recommended as a first-line choice, but acute monotherapy studies have failed. Valproate is generally mentioned as a second-line treatment. Lithium monotherapy is also suggested by most guidelines as a first-line treatment, but its efficacy in acute use is not totally clear. Amongst atypical antipsychotics, quetiapine, in monotherapy or as adjunctive treatment, is recommended by most guidelines as a first-line choice. Olanzapine monotherapy is also suggested by some guidelines and is approved in Japan. Armodafinil, pramipexole, ketamine, and lurasidone are recent proposals. Long-term treatment in bipolar disorder is strongly recommended, but guidelines do not recommend the use of antidepressants as a maintenance treatment. Lithium, lamotrigine, valproate, olanzapine, quetiapine, and aripiprazole are the recommended first-line maintenance options.

Abstract
BACKGROUND Olanzapine plus fluoxetine combination (OFC) is one of the current approaches for treating the depressive phase of bipolar disorder. Our objective was to synthesize the evidence on the efficacy of OFC therapy in bipolar depressed patients. METHODS We searched for randomized controlled trials (RCTs) on MEDLINE, Embase and other databases. Independent researchers selected the studies and extracted the data. The GRADE approach was used to assess the quality of the evidence. The Mantel-Haenszel random effect model was used to perform the meta-analyses. RESULTS From 627 unique records retrieved, four RCTs were included (1330 patients). OFC improved the response compared to olanzapine (relative risk [RR]=1.58; 95% confidence interval [95% CI]: 1.27, 1.97) and to placebo (RR=1.99; 95% CI: 1.49, 2.65) but not to lamotrigine (low-quality evidence). Similar results were found for remission and relapse rates. No differences were identified for levels of depression and mania symptoms (low-quality evidence) and incidence of mania (moderate-quality evidence). Adverse effects were more common in patients treated with OFC than in those treated with lamotrigine (RR=1.13; 95% CI: 1.04, 1.23), but no difference was found relative to the patients treated with olanzapine (low-quality evidence). LIMITATIONS Despite the totality of the evidence included, there are few RCTs available regarding the efficacy of OFC therapy for bipolar depression. The risk of attrition and reporting bias is also a concern. CONCLUSIONS OFC therapy improved the response, remission, and relapse rates among other outcomes. However, a worse profile of adverse reactions was observed in some comparisons. These data clarify the therapeutic use of OFC as an option to olanzapine in bipolar depression. The quality of the evidence could be improved by additional comparisons and higher rates of treatment adherence.

Abstract
BACKGROUND While factors associated with mixed states have been extensively studied, data are scant regarding the clinical heterogeneity of mixed states. The EMBLEM study was a prospective, observational study on patients with manic and mixed states. We describe and compare baseline characteristics and 24-month clinical course of mixed states with predominant depressive symptoms (MSDS) and mixed states with predominant manic symptoms (MSMS). METHODS Adult inpatients/outpatients with bipolar disorder were enrolled within the standard course of care if they initiated or changed oral medication for acute mania or mixed states. A logistic regression was used to identify the baseline factors associated with each polarity. Comparisons with mixed episode without symptom predominance (OMS) were performed for informational purpose only. RESULTS About 573 mixed patients were analyzed (23.7% of the cohort): 59.5% (n=341) had MSMS, 11.9% (n=68) had MSDS, and 28.6% (n=164) had OMS. At baseline, hallucinations/delusions during the index episode, inpatient status, high CGI-BP overall score, and low education level were more often associated with MSMS versus MSDS. Alcohol abuse or dependence and selective serotonin reuptake inhibitor (SSRI) or benzodiazepine use at inclusion were significantly more frequent with MSDS. MSDS had a significantly lower 24-month recurrence rate than MSMS; MSMS experienced more switches to mania whereas MSDS switched more to depression. LIMITATIONS The post hoc dimensional definitions in the study require caution in the interpretation of the results. CONCLUSION These results present evidence of clinical heterogeneity within mixed states. Predominant manic or depressive symptoms within mixed episode could influence clinicians' decisions in term of hospitalization, treatment, and perception of bipolar severity.

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
Bipolar depression represents a high priority research field, due to its pervasiveness, and high economic and personal (suicidality, impaired function, quality of life) costs, and the limited evidence base to inform therapeutics. Mood stabilizers and second-generation antipsychotics for bipolar depression are commonly only partially effective, and their side-effects may overlap with depressive symptoms such as hypersomnia, daytime drowsiness, fatigue, psychomotor retardation, and weight gain. Moreover, the use of antidepressants in bipolar depression is controversial due to concerns regarding the risks of inefficacy or switching to mood elevation. Stimulants and related compounds such as modafinil and armodafinil have on occasion been used as adjuncts in bipolar depressed patients with encouraging results, but their use is limited by the paucity of systematic evidence of efficacy and safety. The present review aims to provide an updated perspective on the use of stimulants and stimulant-like medications in adult bipolar depression, considering not only recent randomized controlled trials, but also open naturalistic studies, in order to clarify the strengths and limitations of using these agents.

Abstract
BACKGROUND Studies on mixed depression have been conducted so far on the basis of DSM-IV manic symptoms, i.e., a list of 7 symptoms which may provide limited information on the subsyndromal features associated with a full depressive episode. METHODS As part of the EPIDEP National Multisite French Study of 493 consecutive DSM-IV major depressive patients evaluated in at least two semi-structured interviews 1 month apart, 102 (23.8%) were classified as mixed depressives (≥3 hypomanic symptoms), and 146 (34%) as pure depressives (0 hypomanic symptom), after exclusion of bipolar I patients; hypomanic symptoms were assessed with the Multiple Visual Analog Scales of Bipolarity (MVAS-BP, 26 items) of Ahearn-Carroll in a self assessment format. A narrower definition of mixed depression, resting on those MVAS-BP items referring to DSM-IV hypomanic symptoms was also tested, as a sensitivity analysis. RESULTS Compared to pure depressives, mixed depressive patients had more psychotic symptoms, atypical features and suicide attempts during their index episode; their illness course was characterized by early age at onset, frequent episodes, rapid cycling, and comorbidities. Mixed depressive patients were more frequently bipolar with a family history of bipolar disorder, alcohol abuse, and suicide. A dose-response relationship was found between intradepression hypomania and several clinical features, including temperament measures. The following independent variables were associated with mixed depression: hyperthymic temperament, cyclothymic temperament, irritable temperament, and alcohol abuse. Using the narrower definition of mixed depression missed risk factors such as suicidality and comorbidities. LIMITATIONS The following are the limitations of this study: retrospective design, recall bias, lack of sample homogeneity, no cross-validation of findings by hetero-evaluation of hypomanic symptoms. CONCLUSIONS EPIDEP data showed the feasibility and face validity of self-assessment of intradepressive hypomania. They replicated previous findings on the severity and high suicidal risk of mixed depression profile. They confirmed, for mixed depression, that mixed states occur when mood episodes are superimposed upon temperaments of opposite polarity. They finally suggested that a definition of mixed depression only based on DSM-IV-TR hypomanic symptoms may not allow to identify the most unstable subforms of the entity.

Abstract
INTRODUCTION The role of antidepressant drugs in acute and maintenance treatment of bipolar depression is a matter of debate that cannot be decided from the evidence available in the current literature. AREAS COVERED This review includes two sections: in the first, important contributions from the current literature, emphasizing randomized controlled trials (RCTs) and meta-analysis, highlight current controversies and methodological issues; in the second, the impact of mixed depressive features in bipolar depression is evaluated from a psychopathological perspective. EXPERT OPINION Methodological issues may complicate evaluation of the evidence from RCTs regarding antidepressants and mixed states. Moreover, nosological constructs may also contribute to the inconclusive findings, by introducing heterogeneity in patient selection and diagnosis. Acknowledging the impact of mixed features in the course of bipolar depression, essentially by the careful reading of classical Kraepelinian contributions, could enhance clinical management. This would in turn allow a more judicious use of antidepressants, ideally helping to shed some light on the much controversial 'antidepressant-related suicidality', and help to further clarify the reasons for the current literature discordance on this topic.

Abstract
The current statement is a systematic review of the available data concerning the efficacy of medication treatment of bipolar disorder (BP). A systematic MEDLINE search was made concerning the treatment of BP (RCTs) with the names of treatment options as keywords. The search was updated on 10 March 2012. The literature suggests that lithium, first and second generation antipsychotics and valproate and carbamazepine are efficacious in the treatment of acute mania. Quetiapine and the olanzapine-fluoxetine combination are also efficacious for treating bipolar depression. Antidepressants should only be used in combination with an antimanic agent, because they can induce switching to mania/hypomania/mixed states/rapid cycling when utilized as monotherapy. Lithium, olanzapine, quetiapine and aripiprazole are efficacious during the maintenance phase. Lamotrigine is efficacious in the prevention of depression, and it remains to be clarified whether it is also efficacious for mania. There is some evidence on the efficacy of psychosocial interventions as an adjunctive treatment to medication. Electroconvulsive therapy is an option for refractory patients. In acute manic patients who are partial responders to lithium/valproate/carbamazepine, adding an antipsychotic is a reasonable choice. The combination with best data in acute bipolar depression is lithium plus lamotrigine. Patients stabilized on combination treatment might do worse if shifted to monotherapy during maintenance, and patients could benefit with add-on treatment with olanzapine, valproate, an antidepressant, or lamotrigine, depending on the index acute phase. A variety of treatment options for BP are available today, but still unmet needs are huge. Combination therapy may improve the treatment outcome but it also carries more side-effect burden. Further research is necessary as well as the development of better guidelines and algorithms for the step-by-step rational treatment.

Abstract
Bipolar Disorder (BD) is a common psychiatric illness that has a recurring course and 17% - 24% lifetime prevalence of suicide attempts. Difficulty in diagnosis and individual variation in response point to a great need for personalized medicine. Studies to date have focused largely on lithium and suggest the idea that different medication responses may reflect different disease mechanisms. An overview of current pharmacogenomic studies will be presented and needs and future directions discussed.

Abstract
Bipolar disorder is a disease which causes major disability. The disease has both a manic and depressive component. Current standard of care consists of atypical antipsychotics for the treatment of mania, antidepressants for the treatment of depression, and mood stabilizers for the maintenance of euthymia. The molecular mechanisms which cause the disease are not well understood. Genome wide association studies have provided a set of genes which are linked to the disease. These genes show linkage to physiological and neuroanatomical alterations which are also seen in bipolar disorder.

Abstract
Bipolar disorder (BD) is a prevalent and disabling condition, often comorbid with other medical and psychiatric conditions and frequently misdiagnosed. International treatment guidelines for BD recommend the use of mood stabilizers - either in monotherapy or in association - as the gold standard in both acute and long-term therapy. Commonly used in the clinical practice of BD, mood stabilizers have represented an evolving field over the last few years. The concept of stabilization, in fact, has been stressed as the ultimate objective of the treatment of BD, given the chronic and recurrent nature of the illness, which accounts for its significant levels of impairment and disability. To date, different compounds are included within the broad class of mood stabilizers, with lithium, anticonvulsants and, more recently, atypical antipsychotics being the most representative agents. This article is aimed at providing an updated review of the available literature in relation to the role of mood stabilizers in BD, with particular emphasis on their mechanism of action, main clinical aspects and specific use in the different phases of BD treatment, according to the most recently published international treatment guidelines.

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
INTRODUCTION Bipolar depression poses a great burden on patients and their families due to its duration, associated functional impairment, and limited treatment options. Given the complexity of the disorder and the advances in treatment, a number of clinical guidelines, consensus statements and expert opinions were developed with the aim to standardize treatment and provide clinicians with treatment algorithms for every-day clinical practice. Unfortunately, they often led to conflicting conclusions and recommendations due to limitations of the available literature. As findings emerge from research literature, guidelines quickly become obsolete and need to be updated or revised. Many guidelines have been updated in the last 5 years, after the last review of bipolar disorder (BD) treatment guidelines. OBJECTIVE The purpose of this work is to systematically review guidelines, consensus meetings and treatment algorithms on the acute treatment of bipolar depression updated or published since 2005, to critically underline common and critical points, highlight limits and strengths, and provide a starting point for future research MATERIALS AND METHODS The MEDLINe/PubMed/Index Medicus, PsycINFO/PsycLIT, Excerpta Medica/EMBASE, databases were searched using "depression", "bipolar", "manic-depression", "manic-depressive" and "treatment guidelines" as key words RESULTS The search returned 204 articles. Amongst them, there were 28 papers concerning structured treatment algorithms and/or guidelines suggested by official panels. After excluding those guidelines that were not performed by scientific societies or international groups and those published before 2005, the final selection yielded 7 papers When looking into guidelines content, the results indicate a trend to the gradual acceptance of the use of the atypical antipsychotic quetiapine as monotherapy as first-line treatment. Antidepressant monotherapy is discouraged in most of them, although some support the use of antidepressants in combination with antimanic agents for a limited period of time. Lamotrigine has become a highly controversial option. CONCLUSION The management of bipolar depression is complex and should be differentiated from management of unipolar depression. Guidelines may be useful instruments for helping clinicians to choose and plan bipolar depression treatment by integrating the more updated scientific knowledge with every-day clinical practice and patient-specific factors; however, a further effort is needed in order to improve guidelines implementation in clinical practice. The latest updates on treatment guidelines for bipolar depression give priority to novel treatment approaches, such as quetiapine, over more traditional ones, such as lithium or antidepressants. Lamotrigine is a controversial option.

Abstract
Poor adherence to pharmacotherapy during maintenance-phase treatment of bipolar disorder is a common occurrence, exposing patients to a high risk of illness relapses, rehospitalization and other negative outcomes. In view of this, there has been a reawakening of interest in the potential of long-acting injectable antipsychotic medications to improve treatment outcome during bipolar maintenance therapy. Indeed, long-acting injectable medications have practical advantages of assuring delivery of medication at a prescribed dose, and perhaps also making it easier to monitor adherence, at least to the long-acting drug. However, there are important limitations to the long-term use of depot typical neuroleptics in patients with bipolar disorder, including risk of extrapyramidal side effects and tardive dyskinesia, which may exceed that of patients with schizophrenia, and the potential for treatment-emergent exacerbation of depressive symptoms. Long-acting injectable risperidone (RLAI) has recently been approved for maintenance treatment in patients with bipolar I disorder. Evidence supporting the use of RLAI for this indication consists of several nonrandomized, open-label studies; one randomized, open-label trial; and two adequately powered randomized, double-blind trials. In general, these studies have shown RLAI to be effective for the prevention of relapse or hospitalization during bipolar maintenance treatment. In the double-blind studies, RLAI was associated with reduced relapse rates, increased time to relapse and greater control of clinical symptoms during maintenance treatment following initial stabilization, compared with oral medication treatment or placebo injection. RLAI appeared to be more effective for preventing manic/mixed episodes than depressive episodes. RLAI showed good tolerability across studies; however, dose-related extrapyramidal effects, sedation, weight gain and prolactin elevation may occur during long-term treatment. Responder-enriched designs and exclusion of important clinical subgroups in the double-blind trials may limit translation of these results to routine care settings.

Prog Neuropsychopharmacol Biol Psychiatry 2010; 34:1402-11.

Abstract
Ginseng has been used for mood adjustment in traditional Chinese medicine for thousands of years. Our previous study has shown that, total ginsenosides, the major pharmacologically functional ingredients of ginseng, possess antidepressant activity. In the present study, we hypothesized that an intestinal metabolite of ginseng, 20(S)-protopanaxadiol (code name S111), as a post metabolism compound (PMC) of ingested ginsenosides, may be responsible for the antidepressant activity of ginseng. To test this hypothesis, antidepressant-like activity of orally given S111 was measured in animal tests including tail suspension test, forced swimming test and rat olfactory bulbectomy depression model. In all those tests, S111 demonstrated antidepressant-like activity as potent as fluoxetine. S111 treated bulbectomy animals had higher levels of monoamine neurotransmitters in the brain and in vitro reuptake assay showed that S111 had a mild inhibitory effect. Furthermore, S111 but not fluoxetine significantly reduced brain oxidative stress and down-regulated serum corticosterone concentration in bulbectomy animals. No disturbance to central nervous system (CNS) normal functions were found in S111 treated animals. These results suggest that the ginseng active metabolite S111 is a potential antidepressant. Since the monoamine reuptake activity of this compound is rather weak, it remains to be investigated whether its antidepressant-like effect is by mechanisms that are different from current antidepressants. Furthermore, this study has demonstrated that post metabolism compounds (PMCs) of herb medicines such as S111 may be a novel source for drug discovery from medicinal herbs.

Abstract
OBJECTIVE The singular phenomenon of switching from depression to its opposite state of mania or hypomania, and vice versa, distinguishes bipolar disorder from all other psychiatric disorders. Despite the fact that it is a core aspect of the clinical presentation of bipolar disorder, the neurobiology of the switch process is still poorly understood. In this review, we summarize the clinical evidence regarding somatic interventions associated with switching, with a particular focus on the biologic underpinnings presumably involved in the switch process. DATA SOURCES Literature for this review was obtained through a search of the MEDLINE database (1966-2008) using the following keywords and phrases: switch, bipolar disorder, bipolar depression, antidepressant, SSRIs, tricyclic antidepressants, norepinephrine, serotonin, treatment emergent affective switch, mania, hypomania, HPA-axis, glucocorticoids, amphetamine, dopamine, and sleep deprivation. STUDY SELECTION All English-language, peer-reviewed, published literature, including randomized controlled studies, naturalistic and open-label studies, and case reports, were eligible for inclusion. DATA SYNTHESIS Converging evidence suggests that certain pharmacologic and nonpharmacologic interventions with very different mechanisms of action, such as sleep deprivation, exogenous corticosteroids, and dopaminergic agonists, can trigger mood episode switches in patients with bipolar disorder. The switch-inducing potential of antidepressants is unclear, although tricyclic antidepressants, which confer higher risk of switching than other classes of antidepressants, are a possible exception. Several neurobiological factors appear to be associated with both spontaneous and treatment-emergent mood episode switches; these include abnormalities in catecholamine levels, up-regulation of neurotrophic and neuroplastic factors, hypothalamic-pituitary-adrenal axis hyperactivity, and circadian rhythms. CONCLUSIONS There is a clear need to improve our understanding of the neurobiology of the switch process; research in this field would benefit from the systematic and integrated assessment of variables associated with switching.

Abstract
Evidence suggests that antidepressant treatment may in some cases result in worsening depression and increased risk of suicidality in pediatric and adolescent patients. The United States Food and Drug Administration requires that antidepressants carry a black box warning regarding such a risk in patients up to age 24. Many studies of antidepressant-induced suicidality among adults have also reported an increased risk, while several other investigations involving that population have not supported such a finding. This article provides an update of the controversy surrounding antidepressants as a potential cause of suicidal ideations or behavior. Antidepressant-induced suicidality appears to be an uncommon occurrence but also a legitimate phenomenon. Close monitoring and a follow-up care should be provided for patients after initiation of a new antidepressant.

Abstract
OBJECTIVES These guidelines are based on a first edition that was published in 2002, and have been edited and updated with the available scientific evidence until September 2009. Their purpose is to supply a systematic overview of all scientific evidence pertaining to the treatment of acute bipolar depression in adults. METHODS The data used for these guidelines have been extracted from a MEDLINE and EMBASE search, from the clinical trial database clinicaltrials.gov, from recent proceedings of key conferences, and from various national and international treatment guidelines. Their scientific rigor was categorised into six levels of evidence (A-F). As these guidelines are intended for clinical use, the scientific evidence was finally assigned different grades of recommendation to ensure practicability. RESULTS We identified 10 pharmacological monotherapies or combination treatments with at least limited positive evidence for efficacy in bipolar depression, several of them still experimental and backed up only by a single study. Only one medication was considered to be sufficiently studied to merit full positive evidence. CONCLUSIONS Although major advances have been made since the first edition of this guideline in 2002, there are many areas which still need more intense research to optimize treatment. The majority of treatment recommendations is still based on limited data and leaves considerable areas of uncertainty.

Abstract
The risk of suicidal behavior associated with antidepressant treatment is an issue of debate and concern. The US FDA has required that antidepressants carry a black box warning that there may be a risk of suicidal ideations in depressed pediatric patients treated with these medications, and recently extended the warning to include individuals up age 24. However studies of antidepressant-induced suicidality in adults have yielded contradictory findings and conclusions. This article discusses investigations of this poorly understood phenomenon and the clinical implications of research findings and FDA warnings for clinicians treating adults with depression. Although antidepressant-induced suicidality apparently occurs only rarely, close monitoring and follow up care after the initiation of a new antidepressant is indicated.

Abstract
BACKGROUND Although depression accounts for a large part of the burden associated with bipolar disorder, its drug treatment has been under-studied. OBJECTIVE To provide the best available evidence supporting the pharmacotherapy of bipolar depression. METHODS A systematic review was conducted, focusing on randomized, controlled trials (RCTs) and meta-analyses. RESULTS/CONCLUSIONS Despite FDA approval of both the olanzapine-fluoxetine combination and quetiapine for the treatment of acute bipolar depression, independent RCTs (i.e., not trials conducted 'under the umbrella' of a drug company) have not found any drug to have antidepressant effects similar to those seen in unipolar depression. A practice-based suggestion, valuable for both short- and long-term treatment, might be to have a background of mood stabilizers and to add drugs, following one of several treatment options, trusting to find a drug with a degree of effectiveness by trial and error. The list of drugs that could be used would include all the current antidepressants, the olanzapine-fluoxetine combination and probably quetiapine too. Special features and situations might also influence treatment options.
