Levrat V, Favre S, Richard-Lepouriel H. Current practices of psychoeducation interventions with persons with bipolar disorders: a literature review. Front Psychiatry 2024; 14:1320654. [PMID: 38250257 PMCID: PMC10797008 DOI: 10.3389/fpsyt.2023.1320654] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/12/2023] [Accepted: 12/06/2023] [Indexed: 01/23/2024] Open
Abstract
This review sought to summarize the literature on current practices and forms of psychoeducation in the management of patients with bipolar disorder (BD), including only randomized controlled trials to ensure the best level of evidence. An extensive review of the available literature was conducted using PubMed/MEDLINE, Embase, and PsychInfo databases from inception to April 28th, 2022. The search yielded 381 studies. Seventy articles were included after removing duplicates and applying the inclusion/exclusion criteria. A best-evidence synthesis was used to identify the key results of each study and summarize the outcomes. Eleven descriptive categories were made. They encompass different forms of psychoeducation compared or combined with other psychosocial interventions, varying in setting (individual or group), with or without family members, structured or unstructured, mediated or not by digital tools (smartphone, internet). Globally, these studies show that psychoeducation is important in the treatment of BD, as it leads to a decrease in relapses, mood episodes, hospitalizations, and improved functioning or quality of life. Some studies also showed the benefits of psychoeducation on the patient's level of knowledge of pharmacological treatment and the disorder or compliance with medication, as well as reduced self-stigma. The limitations of this review are linked to the selection of only RCTs and the reliance on their post-hoc analyses. This review confirms the benefit of psychoeducation and psychosocial interventions on the evolution of BD (in different outcomes, including quality of life, relapse, and rehospitalization rates, for example). More recent interventions, such as mindfulness or online psychoeducation, represent an interesting option but more evidence is needed.

Transcranial direct current stimulation for bipolar depression: systematic reviews of clinical evidence and biological underpinnings. Prog Neuropsychopharmacol Biol Psychiatry 2023; 121:110672. [PMID: 36332699 DOI: 10.1016/j.pnpbp.2022.110672] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/19/2022] [Revised: 10/09/2022] [Accepted: 10/26/2022] [Indexed: 11/08/2022]
Abstract
Despite multiple available treatments for bipolar depression (BD), many patients face sub-optimal responses. Transcranial direct current stimulation (tDCS) has been advocated in the management of different conditions, including BD, especially in treatment-resistant cases. The optimal dose and timing of tDCS, the mutual influence with other concurrently administered interventions, long-term efficacy, overall safety, and biological underpinnings nonetheless deserve additional assessment. The present study appraised the existing clinical evidence about tDCS for bipolar depression, delving into the putative biological underpinnings with a special emphasis on cellular and molecular levels, with the ultimate goal of providing a translational perspective on the matter. Two separate systematic reviews across the PubMed database since inception up to August 8th 2022 were performed, with fourteen clinical and nineteen neurobiological eligible studies. The included clinical studies encompass 207 bipolar depression patients overall and consistently document the efficacy of tDCS, with a reduction in depression scores after treatment ranging from 18% to 92%. The RCT with the largest sample clearly showed a significant superiority of active stimulation over sham. Mild-to-moderate and transient adverse effects are attributed to tDCS across these studies. The review of neurobiological literature indicates that several molecular mechanisms may account for the antidepressant effect of tDCS in BD patients, including the action on calcium homeostasis in glial cells, the enhancement of LTP, the regulation of neurotrophic factors and inflammatory mediators, and the modulation of the expression of plasticity-related genes. To the best of our knowledge, this is the first study on the matter to concurrently provide a synthesis of the clinical evidence and an in-depth appraisal of the putative biological underpinnings, providing consistent support for the efficacy, safety, and tolerability of tDCS.

Efficacy, Safety, and Retention Rate of Extended-Release Divalproex Versus Conventional Delayed-Release Divalproex: A Meta-Analysis of Controlled Clinical Trials. Front Pharmacol 2022; 13:811017. [PMID: 35479307 PMCID: PMC9037144 DOI: 10.3389/fphar.2022.811017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2021] [Accepted: 02/23/2022] [Indexed: 11/13/2022] Open
Abstract
Purpose: A novel once-daily divalproex-extended release (ER) dose formulation has been developed; this formulation prolongs the therapeutic serum levels of the drug, compared with the twice-daily conventional divalproex-delayed release (DR) formulation. This study aimed to systematically examine and compare the efficacy, safety, and retention rates of the ER divalproex (VPA-ER) and conventional DR divalproex (VPA-DR) formulations. Methods: Randomized control trials (RCTs) reporting the efficacy, adverse events (AEs), and medication compliance of ER and DR divalproex were searched in online databases, including PubMed, Embase, and Cochrane Library databases, by searching MeSH words and term words. Observational studies with potential biases were excluded. The meta-analysis was performed using Stata 16.0 software. Findings: Thirteen RCTs, involving 1,028 participants, were included in this meta-analysis. Efficacy, AEs, and drug retention rates were the main study outcomes. According to our study, VPA-ER presented clinically significant benefits compared with the placebo in the population with bipolar disorder (BD) (39.5% versus 27.2%, p < 0.001). A similar efficacy of VPA-ER and VPA-DR in controlling seizures was observed in epilepsy patients (87.4% versus 86.5%, p = 0.769). A significantly lower incidence of AEs was reported in the VPA-ER group than in the placebo group (26.8% versus 34.8%, p = 0.003). By contrast, there was no evidence of difference in safety between VPA-ER and VPA-DR (29.4% versus 30.5%, p = 0.750). In addition, the drug retention rate was significantly lower in the VPA-ER group than in the placebo group (76.0% versus 82.7%, p = 0.020), especially in migraine patients (p = 0.022) and in patients who were treated for fewer than 4 weeks (p = 0.018). Implications: The efficacy of VPA-ER was significantly superior to that of the placebo treatment, which provided efficacy similar to that of conventional VPA-DR. VPA-ER is well tolerated with a low rate of AEs compared to the placebo. In addition, the acceptable medicine compliance of VPA-ER was conducive to the long-term maintenance treatment of chronic diseases. Although we analyzed open labels and crossover design RCTs, large-scale multicenter studies on the efficacy and medicine compliance of new ER formulations with less AEs are required to validate our conclusion.

Designing and testing of a health-economic Markov model to assess the cost-effectiveness of treatments for Bipolar disorder: TiBipoMod. Front Psychiatry 2022; 13:1030989. [PMID: 36440423 PMCID: PMC9684337 DOI: 10.3389/fpsyt.2022.1030989] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/29/2022] [Accepted: 10/20/2022] [Indexed: 11/11/2022] Open
Abstract
BACKGROUND Bipolar disorder is an often recurrent mood disorder that is associated with a significant economic and health-related burden. Increasing the availability of health-economic evidence may aid in reducing this burden. The aim of this study is to describe the design of an open-source health-economic Markov model for assessing the cost-effectiveness of interventions in the treatment of Bipolar Disorders type I and II, TiBipoMod. METHODS TiBipoMod is a decision-analytic Markov model that allows for user-defined incorporation of both pharmacological and non-pharmacological interventions for the treatment of BD. TiBipoMod includes the health states remission, depression, (hypo)mania and death. Costs and effects are modeled over a lifetime horizon from a societal and healthcare perspective, and results are presented as the total costs, Quality-Adjusted Life Years (QALY), Life Years (LY), and incremental costs per QALYs and LYs gained. RESULTS Functionalities of TiBipoMod are demonstrated by performing a cost-utility analysis of mindfulness-based cognitive therapy (MBCT) compared to the standard of care. Treatment with MBCT resulted in an increase of 0.18 QALYs per patient, and a dominant incremental cost-effectiveness ratio per QALY gained for MBCT at a probability of being cost-effective of 71% when assuming a €50,000 willingness-to-pay threshold. CONCLUSION TiBipoMod can easily be adapted and used to determine the cost-effectiveness of interventions in the treatment in Bipolar Disorder type I and II, and is freely available for academic purposes upon request at the authors.

BACKGROUND A novel once-daily divalproex-extended release (VPA-ER) dose formulation has been developed, which prolongs therapeutic serum levels compared with that of twice-daily conventional divalproex-delayed release (VPA-DR). Currently, there is lack of meta-analysis focusing on drug retention rate between VPA-ER and VPA-DR. Thus, our study is the first one that aims to systematically examine and compare the efficacy, safety, and retention rate of VPA-ER and VPA-DR. METHODS Online databases including MEDLINE via PubMed, Cochrane Library, Embase (up to October 30, 2021) will be applied for literature screen.

Abstract
Valproic acid (VPA) is widely used antiepileptic agent which is associated with reproductive toxicity via impairment in oxidative redox. Zinc (Zn) and selenium (Se) are trace element with antioxidant effect that known to be essential for spermatogenesis. In the current study, the protective effect of co-administration of Zn and Se on VPA-induced reproductive toxicity in male rats was evaluated. Forty-eight male rats were divided into 8 groups of six (n=6): Control group (treated with normal saline); VPA only (250, 500, 1,000 mg/kg) group; VPA (500 mg/kg) plus Zn (2 mg/kg) group; VPA (500 mg/kg) plus Se (1.5 mg/kg) group; VPA (500 mg/kg) plus a combination of Zn and Se group; and VPA+vitamin E (20 mg/kg) group. The Animals were sacrificed after 28 days of treatment and sperm analysis was taken. Also, evaluation of oxidative stress markers including malondialdehyde (MDA), protein carbonyl (PC), glutathione (GSH) and histopathological changes were done on testis tissue. Morphological changes and a significant decrease in motility and sperm count in rats treated with VPA were observed. Also, an increase in oxidative stress marker, including MDA and PC and a decrease in GSH level was evident in VPA group. Zn and Se administration was able to protect against sperm abnormality, ameliorate the histological change in testis tissue, and suppressed the increase in oxidative stress markers induced by VPA. These results indicated that combination therapy with Zn and Se showed better an ameliorative effect than each one alone. Therefore, it can be suggested as an effective supplement for reproductive impairment in VPA-treated patient.

Abstract
The 2020 College guidelines for mood disorders banish bipolar II disorder - despite its formal status in Diagnostic and Statistical Manual of Mental Disorders and International Classification of Diseases manuals for more than two decades - and argue that there is no need to partition bipolar disorder into separate sub-types. Their single-entity model is seemingly based on opinion rather than any support from referenced scientific studies. The author challenges the Committee's model of there being only one bipolar disorder and argues that it presents several clinical management risks, particularly of 'over-treatment'.

Abstract
Background and Objectives: This review is dedicated to the use of carbamazepine and its derivatives oxcarbazepine and eslicarbazepine in bipolar disorder and their relative strengths in treating and preventing new depressive or manic episodes. This paper will discuss the evidence of their efficacy relative to the polarity of relapse from controlled acute and maintenance/relapse prevention studies in bipolar patients. Materials and Methods: A Medline search was conducted for controlled acute and maintenance studies with carbamazepine, oxcarbazepine, and eslicarbazepine in bipolar disorder. In addition, abstracts reporting on controlled studies with these medications from key conferences were taken into consideration. Results: Information was extracted from 84 articles on the acute and prophylactic efficacy of the medications under consideration. They all appear to have stronger efficacy in treating acute mania than depression, which also translates to better protection against manic than depressive relapses for carbamazepine. Still, there is a paucity of controlled acute studies on bipolar depression for all and, with the exception of carbamazepine, a lack of long-term monotherapy maintenance data. For eslicarbazepine, the efficacy in bipolar disorder remains largely unknown. Especially with carbamazepine, tolerability issues and drug-drug interactions need to be kept in mind. Conclusions: Two of the medications discussed in this review, carbamazepine and oxcarbazepine, match Class A criteria according to the criteria proposed by Ketter and Calabrese, meaning acute antimanic efficacy, prevention of manic relapses, and not causing or worsening depression.

Abstract
BACKGROUND Cognitive-behavioural therapy aims to increase quality of life by changing cognitive and behavioural factors that maintain problematic symptoms. A previous overview of cognitive-behavioural therapy systematic reviews suggested that cognitive-behavioural therapy was effective for many conditions. However, few of the included reviews synthesised randomised controlled trials. OBJECTIVES This project was undertaken to map the quality and gaps in the cognitive-behavioural therapy systematic review of randomised controlled trial evidence base. Panoramic meta-analyses were also conducted to identify any across-condition general effects of cognitive-behavioural therapy. DATA SOURCES The overview was designed with cognitive-behavioural therapy patients, clinicians and researchers. The Cochrane Library, MEDLINE, EMBASE, PsycINFO, Cumulative Index to Nursing and Allied Health Literature, Child Development & Adolescent Studies, Database of Abstracts of Reviews of Effects and OpenGrey databases were searched from 1992 to January 2019. REVIEW METHODS Study inclusion criteria were as follows: (1) fulfil the Centre for Reviews and Dissemination criteria; (2) intervention reported as cognitive-behavioural therapy or including one cognitive and one behavioural element; (3) include a synthesis of cognitive-behavioural therapy trials; (4) include either health-related quality of life, depression, anxiety or pain outcome; and (5) available in English. Review quality was assessed with A MeaSurement Tool to Assess systematic Reviews (AMSTAR)-2. Reviews were quality assessed and data were extracted in duplicate by two independent researchers, and then mapped according to condition, population, context and quality. The effects from high-quality reviews were pooled within condition groups, using a random-effect panoramic meta-analysis. If the across-condition heterogeneity was I2 < 75%, we pooled across conditions. Subgroup analyses were conducted for age, delivery format, comparator type and length of follow-up, and a sensitivity analysis was performed for quality. RESULTS A total of 494 reviews were mapped, representing 68% (27/40) of the categories of the International Classification of Diseases, Eleventh Revision, Mortality and Morbidity Statistics. Most reviews (71%, 351/494) were of lower quality. Research on older adults, using cognitive-behavioural therapy preventatively, ethnic minorities and people living outside Europe, North America or Australasia was limited. Out of 494 reviews, 71 were included in the primary panoramic meta-analyses. A modest effect was found in favour of cognitive-behavioural therapy for health-related quality of life (standardised mean difference 0.23, 95% confidence interval 0.05 to 0.41, prediction interval -0.05 to 0.50, I2 = 32%), anxiety (standardised mean difference 0.30, 95% confidence interval 0.18 to 0.43, prediction interval -0.28 to 0.88, I2 = 62%) and pain (standardised mean difference 0.23, 95% confidence interval 0.05 to 0.41, prediction interval -0.28 to 0.74, I2 = 64%) outcomes. All condition, subgroup and sensitivity effect estimates remained consistent with the general effect. A statistically significant interaction effect was evident between the active and non-active comparator groups for the health-related quality-of-life outcome. A general effect for depression outcomes was not produced as a result of considerable heterogeneity across reviews and conditions. LIMITATIONS Data extraction and analysis were conducted at the review level, rather than returning to the individual trial data. This meant that the risk of bias of the individual trials could not be accounted for, but only the quality of the systematic reviews that synthesised them. CONCLUSION Owing to the consistency and homogeneity of the highest-quality evidence, it is proposed that cognitive-behavioural therapy can produce a modest general, across-condition benefit in health-related quality-of-life, anxiety and pain outcomes. FUTURE WORK Future research should focus on how the modest effect sizes seen with cognitive-behavioural therapy can be increased, for example identifying alternative delivery formats to increase adherence and reduce dropout, and pursuing novel methods to assess intervention fidelity and quality.

Abstract
Purpose: To evaluate the incidence and risk of tremor in patients treated with valproic aid (VPA) monotherapy. Methods: We searched the PubMed, Embase, and Cochrane Library databases to gather relevant data on tremor in patients taking VPA and other drugs and performed a meta-analysis using Stata15.1 software. Results: Twenty-nine randomized controlled trials (RCTs) met the inclusion criteria and were included in the meta-analysis. The overall incidence of tremor in patients receiving VPA therapy was 14% [OR = 0.14, 95% CI (0.10–0.17)]. The pooled estimate risk of tremor showed a significant difference between patients treated with VPA and all other drugs [OR = 5.40, 95% CI (3.22–9.08)], other antiepileptic drugs (AEDs) [OR = 5.78, 95% CI (3.18–10.50)], and other non-AEDs [OR = 4.77, 95% CI (1.55–14.72)]. Both a dose of <1,500 mg/d of VPA [included 500 mg/d: OR = 3.57, 95% CI (1.24–10.26), 500–999 mg/d: OR = 3.99, 95% CI (1.95–8.20), 1,000–1,499 mg/d: OR = 8.82, 95% CI (3.25–23.94)] and a VPA treatment duration of <12 m [included ≤ 3 months: OR = 3.06, 95% CI (1.16–8.09), 3–6 months: OR = 16.98, 95% CI (9.14–31.57), and 6–12 months: OR = 4.15, 95% CI (2.74–6.29)] led to a higher risk of tremor than did other drugs, as did higher doses and longer treatment times. Conclusion: Compared with other drugs, VPA led to a higher risk of tremor, and the level of risk was associated with the dose and duration of treatment.

Abstract
BACKGROUND Currently, the evidence for lithium as a maintenance treatment for bipolar disorder type II (BD-II) remains limited. Guidelines commonly extrapolate recommendations for BD-II from available evidence for bipolar disorder type I (BD-I). Comparing the impact of lithium discontinuation is one way of assessing effectiveness in both groups. AIMS To compare the impact of lithium discontinuation on hospital admissions and self-harm in patients with BD-I or schizoaffective disorder (SZD) and patients with BD-II or other bipolar disorder. METHOD Mirror-image study, examining hospital admissions within 2 years before and after lithium discontinuation in both patient groups. This study was part of a retrospective cohort study (LiSIE) into effects and side-effects of lithium for maintenance treatment of bipolar disorder as compared with other mood stabilisers. RESULTS For the whole sample, the mean number of admissions/patient/review period doubled from 0.44 to 0.95 (P<0.001) after lithium discontinuation. The mean number of bed days/patient/review period doubled from 11 to 22 (P = 0.025). This increase in admissions and bed days was exclusively attributable to patients with BD-I/SZD. Not having consulted with a doctor prior to lithium discontinuation or no treatment with an alternative mood stabiliser at the time of lithium discontinuation led to more admissions. CONCLUSIONS The higher relapse risk in patients with BD-I/SZD suggests a higher threshold for discontinuing lithium than for patients with BD-II/other bipolar disorder. In patients with BD-II/other bipolar disorder, however, judged on the impact of discontinuation alone, lithium did not appear to prevent more severe depressive episodes requiring hospital admission.

Abstract
PURPOSE We systematically reviewed studies to provide current evidence about the incidence and risk of alopecia in patients undergoing valproic acid (VPA) therapy. METHODS We retrieved relevant publications and gathered data on alopecia in patients taking VPA and other drugs from prospective studies. RESULTS Twenty-five articles met the inclusion criteria, and the overall incidence of alopecia in patients receiving VPA therapy was 11% (95% confidence interval (CI): 0.08-0.13). The pooled risk of alopecia showed a significant difference between patients treated with VPA and all other drugs (odds ratio (OR) 5.02, 95% CI: 3.58-7.03), other epileptic drugs (AEDs) (OR 4.82, 95% CI: 3.32-7.00) and other non-AEDs (OR 5.84, 95% CI: 2.67-12.81). Compared to other drugs, VPA increased the risk of alopecia both in patients with migraine headaches (OR 6.05, 95% CI: 2.89-12.63) and patients with epilepsy (OR 5.29, 95% CI: 3.53-7.92), and the increase risk was reported more frequently in patients with migraine. Both lower doses (OR 4.38, 95% CI: 2.32-8.25) and shorter treatments (OR 4.98, 95% CI: 2.41-10.25) with VPA posed a high risk of alopecia compared to other drugs, as did higher doses and longer treatment times. CONCLUSIONS Based on our findings, VPA was significantly associated with a risk of alopecia compared to other drugs, and the risk did not depend on the dose and treatment time.

Abstract
OBJECTIVE The aim of the present study was to evaluate the effectiveness of psychoeducation for bipolar I inpatients following remission of a manic episode in a Chinese population. METHOD The study recruited currently medicated bipolar I patients, aged 18-60 years, who were in remission from a manic episode, as determined using the Diagnostic and Statistical Manual of Mental Disorders Fifth Edition (DSM-5). Patients were randomized (1:1) to either eight sessions of group-based psychoeducation (active treatment group) or regular free discussions (control group). The primary outcomes were the rates of any type of recurrence and rehospitalization following treatment. The secondary outcomes were changes in mood symptoms, medication adherence, global functioning, as well as treatment response (as measured using the Clinical Global Impression scale). Subjects were assessed at baseline and then at 2 weeks, and 1, 2, 3, 5, 7, 9, and 12 months following treatment. RESULTS At 1 year, patients receiving the psychoeducation treatment demonstrated significantly less recurrence. Those in the treatment group also showed a significant reduction in mania recurrence but not depressive recurrence, and psychoeducation increased time to remission. Notably, lower rates of rehospitalization were found in the active treatment group. Those receiving the psychoeducation treatment also revealed higher change from baseline on measures of depression (17-item Hamilton Rating Scale for Depression), mania (Young Mania Rating Scale), global functioning (Clinical Global Impression-severity scale and World Health Organization Disability Assessment Schedule) (P<.05). However, there were no significant group differences for the medication adherence scores. CONCLUSION This preliminary evidence suggests that short, group-based psychoeducation benefits currently medicated inpatients following the remission of mania in bipolar I disorder. This intervention warrants further investigation, especially in other Chinese populations. If future studies confirm its benefits, group-based psychoeducation could be incorporated into routine psychiatric inpatient care for bipolar patients in China.

Abstract
Aim: To evaluate the cost–effectiveness of aripiprazole once-monthly 400/300 mg (AOM 400) in maintenance monotherapy treatment of bipolar I disorder (BP-I). Methods: A de novo lifetime Markov model was developed for BP-I using available data for AOM 400 and relevant comparators. Base-case analysis considered costs and outcomes from the US payer perspective. Results: The cost per quality-adjusted life year gained with AOM 400 versus comparators ranged from US$2007 versus oral asenapine to dominance (i.e., lower cost with quality-adjusted life gain) versus long-acting injectable risperidone, paliperidone palmitate, oral cariprazine and best supportive care. Patients treated with AOM 400 were estimated to have fewer mood episodes and hospitalizations per patient (5.37) than comparators (6.33, asenapine or cariprazine; 6.54, risperidone long-acting injectable; 7.64, paliperidone palmitate; and 8.93, best supportive care). Sensitivity analyses showed results were robust to parameter uncertainty. Conclusion: AOM 400 may be considered cost effective in the maintenance monotherapy treatment of BP-I in adults.

Abstract
Valproic acid (VPA) is an antiepileptic drug, which its usage is limited due to its hepatotoxicity. The present study was conducted to investigate the efficacy of zinc (Zn) and selenium (Se), necessary trace elements, against VPA-induced hepatotoxicity in Wistar rats. The animals were divided into five groups: control, VPA 200 mg/kg, VPA + Zn (100 mg/kg), VPA + Se (100 mg/kg), and VPA + Zn + Se. The administration of VPA for four consecutive weeks resulted in decrease in serum level of Zn in rats. Also, an increase in liver marker enzymes (ALT and AST) and also histological changes in liver tissue were shown after VPA administration. Oxidative stress was evident in VPA group by increased lipid peroxidation (LPO), protein carbonyl (PCO), glutathione (GSH) oxidation, and reducing total antioxidant capacity. Zn and Se (100 mg/kg) administration was able to protect against deterioration in liver enzyme, abrogated the histological change in liver tissue, and suppressed the increase in oxidative stress markers. Zn and combination of Zn plus Se treatment showed more protective effects than Se alone. These results imply that Zn and Se should be suggested as effective supplement products for the prevention of VPA-induced hepatotoxicity.

Abstract
BACKGROUND Models incorporating long-term outcomes (LTOs) are not available to assess the health economic impact of attention-deficit/hyperactivity disorder (ADHD). OBJECTIVE Develop a conceptual modelling framework capable of assessing long-term economic impact of ADHD therapies. METHODS Literature was reviewed; a conceptual structure for the long-term model was outlined with attention to disease characteristics and potential impact of treatment strategies. RESULTS The proposed model has four layers: i) multi-state short-term framework to differentiate between ADHD treatments; ii) multiple states being merged into three core health states associated with LTOs; iii) series of sub-models in which particular LTOs are depicted; iv) outcomes collected to be either used directly for economic analyses or translated into other relevant measures. CONCLUSIONS This conceptual model provides a framework to assess relationships between short- and long-term outcomes of the disease and its treatment, and to estimate the economic impact of ADHD treatments throughout the course of the disease.

Abstract
OBJECTIVES Cytokine level alterations suggest a role for the immune system in the pathophysiology of bipolar disorder (BD). Pharmacotherapy is an important confounding factor in clinical research on cytokine levels. In this systematic review we collate the evidence on blood cytokine levels in medication-free BD and the effects of single mood-stabilizing drugs on these levels. METHODS A systematic review was conducted according to the PRISMA statement. We searched the Pubmed and Embase databases for clinical studies reporting either on cytokine levels in medication-free BD or on the effects of single mood-stabilizing drugs on cytokine levels in BD. RESULTS Of the 564 articles screened, 17 were included. Fourteen articles report on medication-free patients with BD and indicate state-related cytokine alterations. Six articles discuss the effect of lithium. Whereas no data on short-term effects of lithium were found, ≥2 months lithium use in euthymic populations is associated with normal cytokine levels. Two studies report no effect of valproate and no studies were found on carbamazepine, lamotrigine or antipsychotics. LIMITATIONS The available studies are characterized by a broad methodological heterogeneity and limited replication between studies. CONCLUSIONS This systematic review suggests the presence of state-related cytokine level alterations in medication-free BD with most evidence pointing to a proinflammatory cytokine response in mania. Euthymia and long-term lithium use are associated with normal cytokine levels. To improve our understanding of the impact of mood-stabilizing drugs on cytokine levels, longitudinal studies with medication-free baseline, randomized controlled single-drug treatment protocols and close mood state monitoring are needed.

Abstract
There is accruing clinical and empirical evidence supporting the efficacy of lamotrigine as a treatment for bipolar II disorder. However, the treatment response experienced by those with 'short duration' hypomania (or 'other specified' bipolar disorder) has been under-researched. We reviewed a clinical sample of 123 patients diagnosed with a bipolar II disorder three months following their initial assessment. A research interview evaluated treatment strategies implemented, depressive and hypomanic episode pattern and functional outcomes. Of patients who had achieved a minimum level of 75 mg of lamotrigine, n = 51 were assigned to the BP II disorder group (i.e., hypomanic episodes lasted four days or longer) and n = 28 to the short duration group (i.e., hypomanic episodes always lasted less than four days). There were no significant differences between the two groups at the three-month follow-up on self-report measures of changes in depressive and hypomanic episode pattern or functioning across six domains (i.e., intimate relationships, family relationships, friendships, work relationships, work performance, overall quality of life), and with the majority of patients reporting some level of improvement. Study limitations include being an observational, uncontrolled design with a relatively small sample size for detecting statistical differences. Nonetheless, lamotrigine appeared to be a suitable medication to be trialled in patients who alternate between depressive episodes and short periods of hypomania, (as for those with DSM-defined hypomanic episodes), and should prompt further investigation.

Abstract
OBJECTIVE To detail the disconnect between the quantified efficacy of the mood stabilizer lamotrigine in its registration controlled trials and its later judged clinical effectiveness and consider some determinants of disconnects between some efficacy trial findings and 'real-world' clinical effectiveness judgments. METHOD Published articles considering lamotrigine as a treatment for the bipolar I or II disorders were selected for review. While randomized controlled trials were weighted, we also consider open trials and effectiveness observations from clinician researchers and demonstrate that lamotrigine has been quite variably judged over time. RESULTS We suggest that the early trials evaluating lamotrigine for acute bipolar disorder depression focused on a suboptimal clinical target, and in so doing, ensured less lamotrigine efficacy compared with trials of bipolar disorder preventative treatment. Moreover, a number of additional methodological limitations compromised analyses. We also detail variable reporting of actual study results. The initial sharp disconnect (between efficacy and effectiveness judgments) has narrowed as lamotrigine has been evaluated and progressively taken up as a maintenance mood stabilizer. CONCLUSION The lamotrigine disconnect story provides a number of salutary lessons that are salient to evaluating the effectiveness and ecological niche of any psychotropic medication. The lamotrigine story presented here argues strongly for the wisdom of encouraging an iterative process between efficacy studies and clinical observation.

Lithium is associated with decrease in all-cause and suicide mortality in high-risk bipolar patients: A nationwide registry-based prospective cohort study. J Affect Disord 2015; 183:159-65. [PMID: 26005778 DOI: 10.1016/j.jad.2015.04.055] [Citation(s) in RCA: 38] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/03/2015] [Revised: 04/29/2015] [Accepted: 04/29/2015] [Indexed: 12/16/2022]
Abstract
BACKGROUND Mortality rates, in particular due to suicide, are especially high in bipolar patients. This nationwide, registry-based study analyses the associations of medication use with hospitalization due to attempted suicides, deaths from suicide, and overall mortality across different psychotropic agents in bipolar patients. METHOD Altogether 826 bipolar patients hospitalized in Finland between 1996-2003 because of a suicide attempt were followed-up for a mean of 3.5 years. The relative risk of suicide attempts leading to hospitalization, completed suicide, and overall mortality during lithium vs. no-lithium, antipsychotic vs. no-antipsychotic, valproic acid vs. no-valproic acid, antidepressant vs. no-antidepressant and benzodiazepine vs. no-benzodiazepine treatment was measured. RESULTS The use of valproic acid (RR=1.53, 95% CI: 1.26-1.85, p<0.001), antidepressants (RR=1.49, 95% CI: 1.23-1.8, p<0.001) and benzodiazepines (RR=1.49, 95% CI: 1.23-1.80, p<0.001) was associated with increased risk of attempted suicide. Lithium was associated with a (non-significantly) lower risk of suicide attempts, and with significantly decreased suicide mortality in univariate (RR=0.39, 95% CI: 0.17-0.93, p=0.03), Cox (HR=0.37, 95% CI: 0.16-0.88, p=0.02) and marginal structural models (HR=0.31, 95% CI: 0.12-0.79, p=0.02). Moreover, lithium was related to decreased all-cause mortality by 49% (marginal structural models). LIMITATIONS Only high-risk bipolar patients hospitalized after a suicide attempt were studied. Diagnosis was not based on standardized diagnostic interviews; treatment regimens were uncontrolled. CONCLUSIONS Maintenance therapy with lithium, but not with other medications, is linked to decreased suicide and all-cause mortality in high-risk bipolar patients. Lithium should be considered for suicide prevention in high-risk bipolar patients.

Abstract
Several reasons justify the need for nonpharmacological interventions for bipolar disorder (BD) in women. This review focuses on psychosocial therapies for BDs in women. The research evidence for a wide range of psychosocial interventions for the management of BDs in women has been presented. All the interventions have some common components like targeting disease management, information regarding illness, and coping skills. There also are distinctive features like cognitive restructuring and self-rated mood charts in cognitive behavior therapy, regulation of sleep/wake cycles and daily routines in interpersonal sleep regulation therapy, and communication skill training in family treatments. Many psychosocial interventions hold promise as adjunctive therapies for bipolar patients. In India, there is a considerable dearth of literature in this area due lack of skilled staff for psychosocial interventions. Future trials need to: Clarify which populations are most likely to benefit from which strategies; identify putative mechanisms of action; systematically evaluate costs, benefits, and generalizability of effects, and record adverse effects.

Abstract
BACKGROUND Lithium is the established standard in the long-term treatment of bipolar disorder, but several new drugs have been assessed for this indication. We did a network meta-analysis to investigate the comparative efficacy and tolerability of available pharmacological treatment strategies for bipolar disorder. METHODS We systematically searched Embase, Medline, PreMedline, PsycINFO, and the Cochrane Central Register of Controlled Trials for randomised controlled trials published before June 28, 2013, that compared active treatments for bipolar disorder (or placebo), either as monotherapy or as add-on treatment, for at least 12 weeks. The primary outcomes were the number of participants with recurrence of any mood episode, and the number of participants who discontinued the trial because of adverse events. We assessed efficacy and tolerability of bipolar treatments using a random-effects network meta-analysis within a Bayesian framework. FINDINGS We screened 114 potentially eligible studies and identified 33 randomised controlled trials, published between 1970 and 2012, that examined 17 treatments for bipolar disorder (or placebo) in 6846 participants. Participants assigned to all assessed treatments had a significantly lower risk of any mood relapse or recurrence compared with placebo, except for those assigned to aripiprazole (risk ratio [RR] 0·62, 95% credible interval [CrI] 0·38-1·03), carbamazepine (RR 0·68, 0·44-1·06), imipramine (RR 0·95, 0·66-1·36), and paliperidone (RR 0·84, 0·56-1·24). Lamotrigine and placebo were significantly better tolerated than carbamazepine (lamotrigine, RR 5·24, 1·07-26·32; placebo, RR 3·60, 1·04-12·94), lithium (RR 3·76, 1·13-12·66; RR 2·58, 1·33-5·39), or lithium plus valproate (RR 5·95, 1·02-33·33; RR 4·09, 1·01-16·96). INTERPRETATION Although most of the drugs analysed were more efficacious than placebo and generally well tolerated, differences in the quality of evidence and the side-effect profiles should be taken into consideration by clinicians and patients. In view of the efficacy in prevention of both manic episode and depressive episode relapse or recurrence and the better quality of the supporting evidence, lithium should remain the first-line treatment when prescribing a relapse-prevention drug in patients with bipolar disorder, notwithstanding its tolerability profile. FUNDING None.

Abstract
BACKGROUND Bipolar disorder (BD) is a chronic illness and is one of the worldwide leading causes of disability. It is often a lifelong illness and incurs a substantial economic burden on the health care system, the patients, and society as a whole. However, there are few studies evaluating the economic impact of alternative strategies in the management of BD. OBJECTIVES We reviewed and critically appraised the available published economic evidence on BD management. In addition, we explored advantages and disadvantages of different methods used in the economic evaluation of the management of BD. METHODS A systematic literature search was undertaken using seven electronic databases to identify all English language articles published between January 1980 and March 2012 that provided data on complete economic evaluations for any treatment strategy for BD. The quality of included studies was appraised according to recommendations from the Cochrane Collaboration. RESULTS A total of 7,284 citations were obtained. After initial screening, 20 eligible studies were identified, five of which were trial-based, and 15 of which were model-based economic evaluations. Given the variability in methods and the quality of the identified studies, no conclusive recommendation for the most cost-effective therapy for BD could be provided. CONCLUSIONS The cost-effectiveness of different treatment strategies varied between settings, and transferability of these results across settings remains questionable. Although additional research using a longer time horizon is required to validate the findings for trial-based economic evaluations, discrete event simulation appears to be the most natural and plausible technique for modeling the cost-effectiveness of alternative BD treatment strategies.

Abstract
OBJECTIVE The objective was to study the outcome of mood stabilizer discontinuation on recurrence in patients with bipolar disorder after at least 5 years of euthymia. METHODS Twenty-three patients diagnosed with bipolar affective disorder according to the International Classification of Diseases, 10th Revision Diagnostic Criteria for Research, receiving mood stabilizer prophylaxis for at least 5 years, had undergone planned discontinuation, and the rates and time to recurrence were studied. RESULTS Twenty (87%) of 23 patients had recurrence, and all of the episodes were manic. Kaplan-Meier survival analysis showed median time to recurrence following discontinuation of mood stabilizer prophylaxis was 10 months (SE, 6.06 months; 95% confidence interval, 0 to 21.89 months). CONCLUSION Four fifths of our patients had recurrence following discontinuation of mood stabilizer prophylaxis within 10 months.

Abstract
BACKGROUND Bipolar disorder (BD) is a chronic and relapsing mental illness with a considerable health-related and economic burden. The primary goal of pharmacotherapeutics for BD is to improve patients' well-being. The use of decision-analytic models is key in assessing the added value of the pharmacotherapeutics aimed at treating the illness, but concerns have been expressed about the appropriateness of different modelling techniques and about the transparency in the reporting of economic evaluations. OBJECTIVES This paper aimed to identify and critically appraise published model-based economic evaluations of pharmacotherapeutics in BD patients. METHODS A systematic review combining common terms for BD and economic evaluation was conducted in MEDLINE, EMBASE, PSYCINFO and ECONLIT. Studies identified were summarised and critically appraised in terms of the use of modelling technique, model structure and data sources. Considering the prognosis and management of BD, the possible benefits and limitations of each modelling technique are discussed. RESULTS Fourteen studies were identified using model-based economic evaluations of pharmacotherapeutics in BD patients. Of these 14 studies, nine used Markov, three used discrete-event simulation (DES) and two used decision-tree models. Most of the studies (n = 11) did not include the rationale for the choice of modelling technique undertaken. Half of the studies did not include the risk of mortality. Surprisingly, no study considered the risk of having a mixed bipolar episode. CONCLUSIONS This review identified various modelling issues that could potentially reduce the comparability of one pharmacotherapeutic intervention with another. Better use and reporting of the modelling techniques in the future studies are essential. DES modelling appears to be a flexible and comprehensive technique for evaluating the comparability of BD treatment options because of its greater flexibility of depicting the disease progression over time. However, depending on the research question, modelling techniques other than DES might also be appropriate in some cases.

Abstract
INTRODUCTION Bipolar disorder is a chronic disease characterized by periods of mania or hypomania, depression, or a combination of both (mixed state). Because bipolar disorder is one of the leading causes of disability, it represents an important economic burden on society. Asenapine (ASE) is a new second-generation antipsychotic developed and approved for the treatment of manic or mixed episodes associated with bipolar disorder. The objective of the present study was to assess the cost-effectiveness of ASE compared to olanzapine (OLA) in the treatment of patients experiencing mixed episodes associated with bipolar I disorder in the context of the Italian National Health Service (NHS). METHODS A pharmacoeconomic model was developed to simulate the management of Italian bipolar I patients with mixed episodes over a 5-year time horizon by combining clinical parameters with resource utilization. An expert panel of Italian psychiatrists and health economists was responsible for adapting a UK model to the Italian context. The primary outcome measure of the economic evaluation was the incremental cost effectiveness ratio, where effectiveness is measured in terms of quality adjusted life-years gained. Scenario analyses, sensitivity analyses, and a probabilistic sensitivity analysis were performed to test the robustness of the model. RESULTS This pharmacoeconomic model showed that ASE resulted to be dominant over OLA; in fact, ASE was associated with lower direct costs (derived largely by the savings from hospitalizations avoided) and also generated a better quality of life. Results were robust to changes in key parameters; both scenario analyses and sensitivity analyses demonstrated model reliability. CONCLUSIONS Results from this study suggest that the management of bipolar I patients with mixed episodes using ASE as alternative to OLA can lead to cost saving for the Italian NHS and improve patients quality of life.

Abstract
OBJECTIVE Around one-third of patients with bipolar I disorder (BD-I) experience mixed episodes, characterized by both mania and depression, which tend to be more difficult and costly to treat. Atypical antipsychotics are recommended for the treatment of mixed episodes, although evidence of their efficacy, tolerability, and cost in these patients is limited. This study evaluates, from a UK National Health Service perspective, the cost-effectiveness of asenapine vs olanzapine in BD-I patients with mixed episodes. METHODS Cost-effectiveness was assessed using a Markov model. Efficacy was informed by a post-hoc analysis of two short-term clinical trials, with response measured as a composite Young Mania Rating Score and Montgomery-Åsberg Depression Rating Scale end-point. Probabilities of discontinuation and relapse to manic, mixed, and depressive episodes were sourced from published meta-analyses. Direct costs (2012-2013 values) included drug acquisition, monitoring, and resource use related to bipolar disorder as well as selected adverse events. Benefits were measured as quality-adjusted life years (QALYs). RESULTS For treating mixed episodes, asenapine generated 0.0187 more QALYs for an additional cost of £24 compared to olanzapine over a 5-year period, corresponding to a £1302 incremental cost-effectiveness ratio. The higher acquisition cost of asenapine was roughly offset by the healthcare savings conferred through its greater efficacy in treating these patients. The model shows that benefits were driven by earlier response to asenapine during acute treatment and were maintained during longer-term follow-up. RESULTS were sensitive to changes in key parameters including short and longer-term efficacy, unit cost, and utilities, but conclusions remained relatively robust. CONCLUSIONS RESULTS suggest that asenapine is a cost-effective alternative to olanzapine in mixed episode BD-I patients, and may have specific advantages in this population, potentially leading to healthcare sector savings and improved outcomes. Limitations of the analysis stem from gaps in clinical and economic evidence for these patients and should be addressed by future clinical trials.

Abstract
BACKGROUND AND OBJECTIVE We recently showed that a pharmacist-led information technology-based intervention (PINCER) was significantly more effective in reducing medication errors in general practices than providing simple feedback on errors, with cost per error avoided at £79 (US$131). We aimed to estimate cost effectiveness of the PINCER intervention by combining effectiveness in error reduction and intervention costs with the effect of the individual errors on patient outcomes and healthcare costs, to estimate the effect on costs and QALYs. METHODS We developed Markov models for each of six medication errors targeted by PINCER. Clinical event probability, treatment pathway, resource use and costs were extracted from literature and costing tariffs. A composite probabilistic model combined patient-level error models with practice-level error rates and intervention costs from the trial. Cost per extra QALY and cost-effectiveness acceptability curves were generated from the perspective of NHS England, with a 5-year time horizon. RESULTS The PINCER intervention generated £2,679 less cost and 0.81 more QALYs per practice [incremental cost-effectiveness ratio (ICER): -£3,037 per QALY] in the deterministic analysis. In the probabilistic analysis, PINCER generated 0.001 extra QALYs per practice compared with simple feedback, at £4.20 less per practice. Despite this extremely small set of differences in costs and outcomes, PINCER dominated simple feedback with a mean ICER of -£3,936 (standard error £2,970). At a ceiling 'willingness-to-pay' of £20,000/QALY, PINCER reaches 59 % probability of being cost effective. CONCLUSIONS PINCER produced marginal health gain at slightly reduced overall cost. Results are uncertain due to the poor quality of data to inform the effect of avoiding errors.

Abstract
There is growing evidence that patients with bipolar affective disorder (BAD), who use medication, respond well to further psychotherapeutic interventions. Internet-based psychoeducation is typically centered on the interaction between a client and therapist via the Internet. Multiple methods were required to investigate existing psychoeducational and psychotherapeutic strategies used on patients suffering from BAD. Systematic reviews and original reports of all trials of psychoeducation in BAD patients were retrieved. Patients with BAD, who were hospitalized in a psychiatric department or attended a day hospital program, were exposed to the first version of the program during the treatment, and then questioned about understandability, comprehensibility, and usefulness of each lecture. Twelve modules of the Internet E-Program for BAD were developed and the intervention was a pilot tested with twelve patients. Internet psychoeducation program for BAD is an intervention designed for universal implementation that addresses heightened learning needs of patients suffering from BAD. It is designed to promote confidence and reduce the number of episodes of the disorder by providing skills in monitoring warning signs, planning daily activities and practicing communication skills.

Abstract
OBJECTIVE The integration of new treatments into the market and routine clinical practice should be dependent on robustness of evidence from randomised controlled trials (RCTs). We assessed study designs of long-term studies for bipolar disorder of all second-generation antipsychotics (SGAs) submitted to the Food and Drug Administration (FDA) and the completeness of evidence submitted to the regulatory agency. METHOD Systematic review of double-blind RCTs comparing SGAs with placebo or active drugs in adults. FDA website and electronic databases were searched until July 2013. RESULTS Six placebo-controlled trials comparing aripiprazole, olanzapine, quetiapine and ziprasidone were found in the FDA website. Electronic searches found four additional RCTs about aripiprazole, olanzapine or quetiapine. All RCTs (either submitted to FDA or not) selected patients who responded to acute treatment to increase the treatment effect observed in the long-term phase (enrichment design). By contrast, in the prescribing information sheets for all SGAs, the reported indication was 'maintenance treatment of bipolar disorder'. CONCLUSION Extrapolation of results from enrichment studies to the more general population of patients should be carried out cautiously because average treatment benefits are likely to be less in unselected patients. Clear guidance for regulatory submission of RCTs is needed.

Abstract
Aims. To determine the prevalence of women of childbearing age with schizophrenia and bipolar disorder exposed to antipsychotic (AP) drugs and mood stabilizers (MS) in Lombardy, a European region of 10 million inhabitants and 1 752 285 women of childbearing age. Methods. The data concerning psychiatric care, drug treatments and pregnancy outcomes were retrieved from local administrative databases during a 12-month census period. Results. During a 12-month census period, 2893 women of childbearing age with schizophrenia (74.8% of all women of childbearing age with schizophrenia) and 918 with bipolar disorder (80.1% of all women of childbearing age with bipolar disorder) were exposed to AP drugs or MS, yielding a prevalence of exposure for women with schizophrenia of 1.65 (95% confidence interval (CI) 1.59-1.71) per 1000 female inhabitants, and for women with bipolar disorder of 0.52 (95% CI 0.49-0.55) per 1000 female inhabitants. Persistent exposure to potentially teratogenic medications accounted for one in every 1000 women of childbearing age. Of the 57 pregnancies in women with schizophrenia, normal delivery was recorded in 23 (40%) cases; of the 26 pregnancies in women with bipolar disorder, normal delivery was recorded in 10 (38%) cases. Conclusions. In women of childbearing age with severe mental disorders, exposure to psychotropic drugs is substantial, which suggests that the issue of reproductive health is epidemiologically relevant and a major public health concern.

Abstract
BACKGROUND Bipolar disorder is a recurrent illness that is amongst the top 30 causes of disability worldwide and is associated with significant healthcare costs. In the past, emphasis was placed solely on the treatment of acute episodes of bipolar disorder; recently, the importance of episode prevention and of minimisation of iatrogenicity has been recognised. For many years, lithium was the only mood stabiliser in common use, and it remains an agent of first choice in the preventative treatment of bipolar disorder. However, an estimated 20% to 40% of patients may not respond adequately to lithium. Valproate is an anticonvulsant drug that has been shown to be effective in acute mania and is frequently used in maintenance treatment of bipolar disorder. When the acceptability of long-term treatment is considered, together with efficacy, the adverse event profile of a medication is also important. This is an update of a Cochrane review first published in 2001 and last updated in 2009. OBJECTIVES 1. To determine the efficacy of valproate continuation and maintenance treatment:a) in preventing or attenuating manic, depressive and mixed episodes of bipolar disorder;b) in preventing or attenuating episodes of bipolar disorder in patients with rapid cycling disorder; and; c) in improving patients' general health and social functioning, as measured by global clinical impression, employment and marital stability.2. To review the acceptability to patients of long-term valproate treatment, as measured by numbers of dropouts and reasons for dropping out, by compliance and by reference to patients' expressed views regarding treatment.3. To investigate the adverse effects of valproate treatment (including general prevalence of side effects) and overall mortality rates. SEARCH METHODS Search of the Cochrane Register of Controlled Trials and the Cochrane Depression, Anxiety and Neurosis Group Register (CCDANCTR) (to January 2013), which includes relevant randomised controlled trials from the following bibliographic databases: The Cochrane Library (all years), EMBASE, (1974 to date), MEDLINE (1950 to date) and PsycINFO (1967 to date). No language restrictions were applied. Reference lists of relevant papers and previous systematic reviews were handsearched. Pharmaceutical companies marketing valproate and experts in this field were contacted for supplemental data. SELECTION CRITERIA Randomised controlled trials allocating participants with bipolar disorder to long-term treatment with valproate or any other mood stabiliser, or antipsychotic drugs, or placebo. Maintenance treatment was defined as treatment instituted specifically or mainly to prevent further episodes of illness. DATA COLLECTION AND ANALYSIS Three review authors independently extracted data. A double-entry procedure was employed by two review authors. Information extracted included study characteristics, participant characteristics, intervention details and outcome measures in terms of efficacy, acceptability and tolerability. For dichotomous data, risk ratios were calculated with 95% confidence intervals (CIs). For statistically significant results, we calculated the number needed to treat for an additional beneficial outcome (NNTB) and the number needed to treat for an additional harmful outcome (NNTH). For continuous data, mean differences (MDs) or standardised mean differences (SMDs) were calculated along with 95% CIs. MDs were used when the same scale was used to measure an outcome; SMDs were employed when different scales were used to measure the same outcome. The primary analysis used a fixed-effect model. Binary outcomes were calculated on a strict intention-to-treat (ITT) basis; dropouts were included in this analysis. When data were missing and the method of "last observation carried forward" (LOCF) had been used to do an ITT analysis, then the LOCF data were used. MAIN RESULTS Six randomised controlled trials (overall 876 participants) lasting 6 to 24 months were included. Two studies (overall 312 participants) compared valproate with placebo, four studies (overall 618 participants) valproate with lithium, one study (overall 23 participants) valproate with olanzapine and one study (overall 220 participants) valproate with the combination of valproate plus lithium. In terms of study quality, most studies reported the methods used to generate random sequence; however, only one study reported enough details on allocation concealment. Four of six included studies described their design as "double blind", but only two trials reported full details about blinding. Valproate was more effective than placebo in preventing study withdrawal due to any mood episode (RR 0.68, 95% CI 0.49 to 0.93; NNTB 8), but no difference in efficacy was found between valproate and lithium (RR 1.02, 95% CI 0.87 to 1.20). Valproate was associated with fewer participants dropping out of treatment for any cause when compared with placebo or lithium (RR 0.82, 95% CI 0.71 to 0.95 and RR 0.87, 95% CI 0.77 to 0.98, respectively). However, combination therapy with lithium plus valproate was more likely to prevent relapse than was monotherapy with valproate (RR 0.78, 95% CI 0.63 to 0.96). Significant differences in adverse event frequencies were found, and lithium was associated with more frequent diarrhoea, polyuria, increased thirst and enuresis, whereas valproate was associated with increased sedation and infection. AUTHORS' CONCLUSIONS Limited evidence supports the efficacy of valproate in the long-term treatment of bipolar disorder. Clinicians and patients should consider acceptability and tolerability profile when choosing between lithium and valproate-their combination or other agents-as long-term treatment for bipolar disorder.

Abstract
BACKGROUND The assumption of consistency, defined as agreement between direct and indirect sources of evidence, underlies the increasingly popular method of network meta-analysis. No evidence exists so far regarding the extent of inconsistency in full networks of interventions or the factors that control its statistical detection. METHODS In this paper we assess the prevalence of inconsistency from data of 40 published networks of interventions involving 303 loops of evidence. Inconsistency is evaluated in each loop by contrasting direct and indirect estimates and by employing an omnibus test of consistency for the entire network. We explore whether different effect measures for dichotomous outcomes are associated with differences in inconsistency, and evaluate whether different ways to estimate heterogeneity affect the magnitude and detection of inconsistency. RESULTS Inconsistency was detected in from 2% to 9% of the tested loops, depending on the effect measure and heterogeneity estimation method. Loops that included comparisons informed by a single study were more likely to show inconsistency. About one-eighth of the networks were found to be inconsistent. The proportions of inconsistent loops do not materially change when different effect measures are used. Important heterogeneity or the overestimation of heterogeneity was associated with a small decrease in the prevalence of statistical inconsistency. CONCLUSIONS The study suggests that changing the effect measure might improve statistical consistency, and that an analysis of sensitivity to the assumptions and an estimator of heterogeneity might be needed before reaching a conclusion about the absence of statistical inconsistency, particularly in networks with few studies.

Abstract
Valproic acid is a widely-used first-generation antiepileptic drug, prescribed predominantly in epilepsy and psychiatric disorders. VPA has good efficacy and pharmacoeconomic profiles, as well as a relatively favorable safety profile. However, adverse drug reactions have been reported in relation with valproic acid use, either as monotherapy or polytherapy with other antiepileptic drugs or antipsychotic drugs. This systematic review discusses valproic acid adverse drug reactions, in terms of hepatotoxicity, mitochondrial toxicity, hyperammonemic encephalopathy, hypersensitivity syndrome reactions, neurological toxicity, metabolic and endocrine adverse events, and teratogenicity.

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 Generalized anxiety disorder (GAD) is one of the most prevalent anxiety disorders, with important implications for patients and healthcare resources. However, few economic evaluations of pharmacological treatments for GAD have been published to date, and those available have assessed only a limited number of drugs. OBJECTIVE To assess the cost effectiveness of pharmacological interventions for patients with GAD in the UK. METHODS A decision-analytic model in the form of a decision tree was constructed to compare the costs and QALYs of six drugs used as first-line pharmacological treatments in people with GAD (duloxetine, escitalopram, paroxetine, pregabalin, sertraline and venlafaxine extended release [XL]) and 'no pharmacological treatment'. The analysis adopted the perspective of the NHS and Personal Social Services (PSS) in the UK. Efficacy data were derived from a systematic literature review of double-blind, randomized controlled trials and were synthesized using network meta-analytic techniques. Two network meta-analyses were undertaken to assess the comparative efficacy (expressed by response rates) and tolerability (expressed by rates of discontinuation due to intolerable side effects) of the six drugs and no treatment in the study population. Cost data were derived from published literature and national sources, supplemented by expert opinion. The price year was 2011. Probabilistic sensitivity analysis was conducted to evaluate the underlying uncertainty of the model input parameters. RESULTS Sertraline was the best drug in limiting discontinuation due to side effects and the second best drug in achieving response in patients not discontinuing treatment due to side effects. It also resulted in the lowest costs and highest number of QALYs among all treatment options assessed. Its probability of being the most cost-effective drug reached 75 % at a willingness-to-pay threshold of £20,000 per extra QALY gained. CONCLUSION Sertraline appears to be the most cost-effective drug in the treatment of patients with GAD. However, this finding is based on limited evidence for sertraline (two published trials). Sertraline is not licensed for the treatment of GAD in the UK, but is commonly used by primary care practitioners for the treatment of depression and mixed depression and anxiety.

Abstract
BACKGROUND This study develops an economic model to evaluate the cost-effectiveness of ethyl-eicosapentaenoic acid (ethyl-EPA) as an adjunct treatment of bipolar I disorder. METHODS A 1-year Markov model is used incorporating three health states: euthymic, manic and depressive. The model was populated using outcomes from a clinical trial on clinical efficacy and other published literature. RESULTS The incremental cost-effectiveness ratio (ICER) per quality-adjusted life year (QALY) of ethyl-EPA in comparison with placebo was estimated to be -£2,782 in 2008/09 prices, the negative ICER indicating ethyl-EPA to be a more effective and less costly treatment option than placebo in terms of cost savings of other resource use. CONCLUSIONS The sensitivity analysis indicated that the results were robust. Future research covering a longer time period using broader costs of the disease will be required to consolidate these findings.

Abstract
There is ample experimental evidence supporting the hypothesis that the brain serotonergic system is involved in the control of chronic social defeat stress (CSDS), depression, and anxiety. The study aimed to analyze mRNA levels of the serotonergic genes in the raphe nuclei of midbrain that may be associated with chronic social defeats consistently shown by male mice in special experimental settings. The serotonergic genes were the Tph2, Sert, Maoa, and Htr1a. The Bdnf and Creb genes were also studied. The experimental groups were composed of male mice with experience of defeats in 21 daily encounters and male mice with the same track record of defeats followed by a no-defeat period without agonistic interactions (relative rest for 14 days). It has been shown that mRNA levels of the Tph2, Maoa, Sert, Htr1a, Bdnf, and Creb genes in the raphe nuclei of defeated mice are decreased as compared with the controls. The expression of the serotonergic genes as well as the Creb gene is not restored to the control level after the 2 weeks of relative rest. mRNA levels of Bdnf gene are not recovered to the control levels, although some upregulation was observed in rested losers. CSDS experience inducing the development of mixed anxiety/depression-like state in male mice downregulates the expression of serotonergic genes associated with the synthesis, inactivation, and reception of serotonin. The Bdnf and Creb genes in the midbrain raphe nuclei are also downregulated under CSDS. Period of relative rest is not enough for most serotonergic genes to recover expression to the control levels.

Abstract
While indicated for schizophrenia and acute mania, ziprasidone's evidence base and use in clinical practice extends beyond these regulatory approvals. We, an invited panel of experts led by a working group of 3, critically examined the evidence and our collective experience regarding the effectiveness, tolerability and safety of ziprasidone across its clinical uses. There was no opportunity for manufacturer input into the content of the review. As anticipated, ziprasidone was found to be effective for its indicated uses, although its utility in mania and mixed states lacked comparative data. Beyond these uses, the available data were either unimpressive or were lacking. An attractive characteristic is its neutral effect on weight thereby providing patients with a non-obesogenic long-term treatment option. Key challenges in practice include the need for dosing on a full stomach and managing its early onset adverse effect of restlessness. Addressing these issues are critical to its long-term success.

Abstract
OBJECTIVE To establish whether lithium or anticonvulsant should be used for maintenance treatment for bipolar affective disorder (BPAD) if the risks of suicide and relapse were traded off against the risk of end-stage renal disease (ESRD). METHOD Decision analysis based on a systematic literature review with two main decisions: (1) use of lithium or at treatment initiation and (2) the potential discontinuation of lithium in patients with chronic kidney disease (CKD) after 20 years of lithium treatment. The final endpoint was 30 years of treatment with five outcomes to consider: death from suicide, alive with stable or unstable BPAD, alive with or without ESRD. RESULTS At the start of treatment, the model identified lithium as the treatment of choice. The risks of developing CKD or ESRD were not relevant at the starting point. Twenty years into treatment, lithium still remained treatment of choice. If CKD had occurred at this point, stopping lithium would only be an option if the likelihood of progression to ESRD exceeded 41.3% or if anticonvulsants always outperformed lithium regarding relapse prevention. CONCLUSION At the current state of knowledge, lithium initiation and continuation even in the presence of long-term adverse renal effects should be recommended in most cases.

Abstract
BACKGROUND Bipolar disorder has a significant impact upon a patient's quality of life, imposing a considerable economic burden on the individual, family members and society as a whole. Several medications are indicated for the acute treatment of mania and depression associated with bipolar disorder as well as for maintenance therapy; however, these have varying efficacy, tolerability and costs. OBJECTIVE The objective of this study was to develop a new discrete-event simulation model to analyse the long-term consequences of pharmacological therapy for the management of bipolar I and II disorders (acute treatment of episodes of mania and depression as well as maintenance therapy). METHODS Probabilities of remission and relapse were obtained from clinical trial data and meta-analyses. Costs (year 2011 values) were assessed from a UK healthcare payer's perspective, and included pharmacological therapy and resource use associated with the treatment of mood events and selected adverse events. The health effects were measured in terms of QALYs. RESULTS For a patient starting with acute depression or in remission at 40 years of age (which was the average age in the clinical trials), quetiapine 300 mg/day was a cost-effective strategy compared with olanzapine 15 mg/day over a 5-year time frame. With acute bipolar depression as a starting episode, the 5-year medical costs were £323 higher and QALYs were 0.038 higher for quetiapine compared with olanzapine, corresponding to a cost-effectiveness ratio of £8600 per QALY gained. CONCLUSION Compared with olanzapine, the results suggest that quetiapine is cost effective as a maintenance treatment for bipolar depression.

Abstract
BACKGROUND Conventional meta-analyses have shown inconsistent results for efficacy of pharmacological treatments for acute mania. We did a multiple-treatments meta-analysis, which accounted for both direct and indirect comparisons, to assess the effects of all antimanic drugs. METHODS We systematically reviewed 68 randomised controlled trials (16,073 participants) from Jan 1, 1980, to Nov 25, 2010, which compared any of the following pharmacological drugs at therapeutic dose range for the treatment of acute mania in adults: aripiprazole, asenapine, carbamazepine, valproate, gabapentin, haloperidol, lamotrigine, lithium, olanzapine, quetiapine, risperidone, topiramate, and ziprasidone. The main outcomes were the mean change on mania rating scales and the number of patients who dropped out of the allocated treatment at 3 weeks. Analysis was done by intention to treat. FINDINGS Haloperidol (standardised mean difference [SMD] -0·56 [95% CI -0·69 to -0·43]), risperidone (-0·50 [-0·63 to -0·38), olanzapine (-0·43 [-0·54 to -0·32], lithium (-0·37 [-0·63 to -0·11]), quetiapine (-0·37 [-0·51 to -0·23]), aripiprazole (-0·37 [-0·51 to -0·23]), carbamazepine (-0·36 [-0·60 to -0·11], asenapine (-0·30 [-0·53 to -0·07]), valproate (-0·20 [-0·37 to -0·04]), and ziprasidone (-0·20 [-0·37 to -0·03]) were significantly more effective than placebo, whereas gabapentin, lamotrigine, and topiramate were not. Haloperidol had the highest number of significant differences and was significantly more effective than lithium (SMD -0·19 [95% CI -0·36 to -0·01]), quetiapine (-0·19 [-0·37 to 0·01]), aripiprazole (-0·19 [-0·36 to -0·02]), carbamazepine (-0·20 [-0·36 to -0·01]), asenapine (-0·26 [-0·52 to 0·01]), valproate (-0·36 [-0·56 to -0·15]), ziprasidone -0·36 [-0·56 to -0·15]), lamotrigine (-0·48 [-0·77 to -0·19]), topiramate (-0·63 [-0·84 to -0·43]), and gabapentin (-0·88 [-1·40 to -0·36]). Risperidone and olanzapine had a very similar profile of comparative efficacy, being more effective than valproate, ziprasidone, lamotrigine, topiramate, and gabapentin. Olanzapine, risperidone, and quetiapine led to significantly fewer discontinuations than did lithium, lamotrigine, placebo, topiramate, and gabapentin. INTERPRETATION Overall, antipsychotic drugs were significantly more effective than mood stabilisers. Risperidone, olanzapine, and haloperidol should be considered as among the best of the available options for the treatment of manic episodes. These results should be considered in the development of clinical practice guidelines. FUNDING None.

Effectiveness of olanzapine monotherapy and olanzapine combination treatment in the long term following acute mania--results of a two year observational study in bipolar disorder (EMBLEM). J Affect Disord 2011; 131:320-9. [PMID: 21195486 DOI: 10.1016/j.jad.2010.11.037] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/17/2009] [Revised: 11/30/2010] [Accepted: 11/30/2010] [Indexed: 11/23/2022]
Abstract
BACKGROUND This study compared the 2-year outcomes of patients with a manic/mixed episode of bipolar disorder taking olanzapine monotherapy or olanzapine in combination with other agents. METHODS EMBLEM (European Mania in Bipolar Longitudinal Evaluation of Medication) is a 2-year, prospective, observational study of clinical and functional outcomes of bipolar patients with an index manic/mixed episode. The study consisted of two phases: acute (12 weeks) and maintenance (follow-up over 2 years). The longitudinal outcome measure was the Clinical Global Impression-Bipolar Disorder scale. Cox regression models compared outcomes of both therapy groups using intention-to-treat and switching medication analysis. Treatment-emergent adverse events were also assessed. RESULTS 1076 patients were included in this analysis. 29% took olanzapine as monotherapy (n = 313) and 71% as combination (n = 763) at 12-weeks post-baseline (end of study acute phase). After adjusting for patient characteristics using switching medication analysis, only relapse rates differed (p = 0.01) in favour of monotherapy-treated patients. There was no significant difference in rates of improvement, remission, and recovery. Patients treated with combination therapy reported more tremor (OR 2.37, 95%CI 1.44-3.89) and polyuria (OR 3.08, 95%CI 1.45-6.54) treatment-emergent events than monotherapy, although weight change was greater in the monotherapy group. LIMITATIONS Unknown confounding and potential selection bias may differentially impact treatment outcomes. CONCLUSIONS EMBLEM patients benefitted from the selected therapy to a similar extent. Differences in patient characteristics between those prescribed monotherapy and combination therapy appear to be clinically relevant in the treatment decision. Physicians must balance the benefits and risks when determining appropriate treatment for individual patients.

Abstract
Transcranial direct current stimulation (tDCS) is a non-invasive method for brain stimulation. Although pilot trials have shown that tDCS yields promising results for major depressive disorder (MDD), its efficacy for bipolar depressive disorder (BDD), a condition with high prevalence and poor treatment outcomes, is unknown. In a previous study we explored the effectiveness of tDCS for MDD. Here, we expanded our research, recruiting patients with MDD and BDD. We enrolled 31 hospitalized patients (24 women) aged 30-70 years 17 with MDD and 14 with BDD (n = 14). All patients received stable drug regimens for at least two weeks before enrollment and drug dosages remained unchanged throughout the study. We applied tDCS over the dorsolateral prefrontal cortex (anodal electrode on the left and cathodal on the right) using a 2 mA-current for 20 min, twice-daily, for 5 consecutive days. Depression was measured at baseline, after 5 tDCS sessions, one week later, and one month after treatment onset. We used the scales of Beck (BDI) and Hamilton-21 items (HDRS). All patients tolerated treatment well without adverse effects. After the fifth tDCS session, depressive symptoms in both study groups diminished, and the beneficial effect persisted at one week and one month. In conclusion, our preliminary study suggests that tDCS is a promising treatment for patients with MDD and BDD.2.

Abstract
BACKGROUND Biennial faecal occult blood testing (FOBT) for individuals aged 60-69 years is the primary screening tool for colorectal cancer (CRC) in the UK NHS, despite a large number of patients undergoing an unnecessary optical colonoscopy (OC) and evidence from modelling studies to suggest that more cost-effective technologies exist. CT colonography (CTC) is an emerging CRC screening technology with the potential to prevent CRC by detecting pre-cancerous polyps and to detect cancer at an earlier stage. OBJECTIVE to assess the impact of introducing CTC into the UK NHS screening programme for CRC on key health outcomes as well as the NHS budget and healthcare resource capacity. METHODS a discrete Markov model was used to reflect the natural history of CRC and the impact of three screening scenarios (biennial FOBT with and without CTC triage of patients referred to OC, and CTC every 5 years) on a range of health outcomes, including the incidence and prevalence of CRC, in a hypothetical cohort of individuals. The yearly costs, health outcomes and healthcare resource capacity requirements were estimated over a 10-year period (2009-18). RESULTS using CTC to follow up FOBT-positive patients (scenario 2) was less costly than directing all FOBT-positive patients to OC (scenario 1); saving £776 283 over 10 years for 100 000 individuals invited for screening (year 2007 values), primarily by avoiding approximately 1700 OCs, but was estimated to require 2200 additional CT scans. Implementing a programme of 5-yearly CTC as a primary screen is expected to be more expensive than FOBT screening over the short term (driven by high screening and diagnosis costs), despite substantial savings in treatment costs for CRC over the 10-year time horizon of the model and improved health outcomes. CONCLUSIONS adding CTC into the existing NHS Bowel Cancer Screening Programme as part of a preventive screening strategy could be less costly to the NHS over the longer term when used to triage FOBT-positive patients to appropriate follow-up. Increased demand for radiology services may be compensated for by reduced demand in endoscopy units.

Abstract
Olanzapine was licensed in the USA by the Food and Drug Administration in 2003 for the prevention of relapse in patients with bipolar disorder when the acute manic episode had responded to treatment with olanzapine. However, olanzapine is commonly used in clinical practice for preventing relapse in patients with bipolar disorder even when acute response has not been demonstrated. The aim of this systematic review and meta-analysis is to determine the effectiveness and acceptability of olanzapine in preventing recurrent mood episodes in bipolar disorder. MEDLINE, EMBASE, the Cochrane Collaboration Depression, Anxiety and Neurosis Controlled Trials Register and the Cochrane Central Register of Controlled up to July 2008 were accessed. Only randomised controlled trials comparing olanzapine with placebo or other active drugs for long-term treatment were included. Two reviewers independently extracted data. Authors were contacted to provide additional data. Of the five trials included in this review, four were conducted by Eli Lilly, the manufacturer of olanzapine. Olanzapine was more effective than placebo at preventing manic relapse, but there was no difference between olanzapine (alone or in combination with lithium or valproate) and placebo (alone or in combination with lithium or valproate) in terms of relapse into any mood episode, as defined as primary outcome by authors in each of the primary studies. We conclude that olanzapine may prevent further manic episodes only in patients who have responded to olanzapine in an acute manic or mixed episode and who have not previously had a satisfactory response to lithium or valproate.
