Predictors of good outcome in patients with refractory bipolar disorder after a drug or a drug and cognitive-behavioral treatment

Assessment Tool of Bipolar Disorder for Primary Health Care: The SAEBD

Mixed states are highly prevalent in patients with bipolar disorder and require comprehensive scales. Considering this, the current study aims to develop a measure to assess the full spectrum of clinical manifestations of bipolar disorder. A sample of 88 patients was evaluated; the Hamilton Depression Scale (HAM-D), Montgomery-Asberg Depression Scale (MADRS), and the Young Mania Rating Scale (YMRS) were applied, together with the preliminary version of the Scale for the Assessment of Episodes in Bipolar Disorder (SAEBD). After analyzing the appropriateness and statistical properties of the items, discriminant analysis and analysis of diagnostic capacity were performed. The discriminant functions correctly classified 100% of the cases in euthymia, predominant depressive symptoms or mixed symptoms, as well as 92.3% of the cases with predominant manic symptoms. Overall, the functions correctly classified 98.9% of the cases. The area under the curve (0.935) showed high capacity to discriminate between clinical and non-clinical cases (i.e., in euthymia). The SAEBD sensitivity was 0.95, specificity was 0.71, the Positive Predictive Value (PPV) was 0.88, the Negative Predictive Value (NPV) was 0.87, the Positive Likelihood Ratio (+LR) was 3.33, and the Negative Likelihood Ratio (−LR) was 0.07. In conclusion, the SAEBD is a promising scale that shows high reliability and validity, as well as diagnostic utility as a screening tool for use in diverse health care settings.

A narrative review of cross-sectional and prospective associations between self-schemas and bipolar disorder

The role of self-concept in bipolar disorder (BD) has not been well understood. The present review utilizes the notion of self-schema and interrogates existing research concerning evidence for cross-sectional and prospective associations between four schema-like constructs (i.e. trait self-esteem, dysfunctional beliefs concerning contingent self-worth, early maladaptive schemas and implicit self-esteem) and various facets of BD. Existing findings demonstrate various types of involvement of self-schemas in BD. Of particular clinical relevance, the present review suggests that low trait self-esteem and dysfunctional beliefs concerning contingent self-worth are risk factors for ongoing BD symptoms and mood episodes. The present review also yields important yet unaddressed questions with respect to the evaluative content of self-schemas associated with the hypo/manic phase of BD.

The Impact of Subsyndromal Bipolar Symptoms on Patient's Functionality and Quality of Life

Subsyndromal symptoms have rarely been in the focus of bipolar research. This may be, in part, due to the fact that there is neither a uniform definition nor do they constitute an indication of regulatory and commercial interest. Nevertheless, they do have a decisive impact on the long-term course of bipolar disorder (BD), and the degree of functionality and quality of life (QoL) is more likely determined by their presence or absence than by acute episodes. Summarizing the literature an estimated 20-50% of patients suffer inter-episodically or chronically from subsyndromal BD. The most prominent symptoms that interfere with functionality are subsyndromal depression, disturbances of sleep, and perceived cognitive impairment, whereas anxiety negatively impacts on QoL. In the absence of evidence-based pharmacological treatments for subsyndromal BD, clinical practice adopts guidelines designed for treatment-resistant full-blown episodes of BD, supplemented by cognitive-behavioral, family focused or social-rhythm-based psychotherapies.

The CINP Guidelines on the Definition and Evidence-Based Interventions for Treatment-Resistant Bipolar Disorder

BACKGROUND

Resistant bipolar disorder is a major mental health problem related to significant disability and overall cost. The aim of the current study was to perform a systematic review of the literature concerning (1) the definition of treatment resistance in bipolar disorder, (2) its clinical and (3) neurobiological correlates, and (4) the evidence-based treatment options for treatment-resistant bipolar disorder and for eventually developing guidelines for the treatment of this condition.

MATERIALS AND METHODS

The PRISMA method was used to identify all published papers relevant to the definition of treatment resistance in bipolar disorder and the associated evidence-based treatment options. The MEDLINE was searched to April 22, 2018.

RESULTS

Criteria were developed for the identification of resistance in bipolar disorder concerning all phases. The search of the literature identified all published studies concerning treatment options. The data were classified according to strength, and separate guidelines regarding resistant acute mania, acute bipolar depression, and the maintenance phase were developed.

DISCUSSION

The definition of resistance in bipolar disorder is by itself difficult due to the complexity of the clinical picture, course, and treatment options. The current guidelines are the first, to our knowledge, developed specifically for the treatment of resistant bipolar disorder patients, and they also include an operationalized definition of treatment resistance. They were based on a thorough and deep search of the literature and utilize as much as possible an evidence-based approach.

Psychoeducation and cognitive-behavioral therapy for patients with refractory bipolar disorder: A 5-year controlled clinical trial

Objective:

The aim of this research, which represents an additional and longer follow-up to a previous trial, was to evaluate a 5-year follow-up study of a combined treatment (pharmacological + psychoeducational and cognitive-behavioral therapy) as compared with a standard pharmacological treatment in patients with refractory bipolar disorder.

Method:

Forty patients were randomly assigned to either an Experimental group–under combined treatment — or a Control group — under pharmacological treatment. Data were analyzed by analysis of variance (ANOVA), with repeated measures at different evaluation time points.

Results:

Between-group differences were significant at all evaluation time points after treatment. Experimental group had less hospitalization events than Control group in the 12-month evaluation (P = 0.015). The Experimental group showed lower depression and anxiety in the 6-month (P = 0.006; P = 0.019), 12-month (P = 0.001; P < 0.001) and 5-year (P < 0.001, P < 0.001) evaluation time points. Significant differences emerged in mania and misadjustment already in the post-treatment evaluation (P = 0.009; P < 0.001) and were sustained throughout the study (6-month: P = 0.006, P < 0.001; 12-month: P < 0.001, P < 0.001; 5-year: P = 0.004, P < 0.001). After 5-year follow-up, 88.9% of patients in the Control group and 20% of patients in the Experimental group showed persistent affective symptoms and/or difficulties in social-occupational functioning.

Conclusions:

A combined therapy is long-term effective for patients with refractory bipolar disorder. Suggestions for future research are commented.

[Influence of a therapeutic patient education (TPE) program on quality of life in bipolar disorder: Preliminary results]

INTRODUCTION

Bipolar disorder is a mental illness that is associated with a long-term impairment in psychosocial functioning and quality of life. The objective of this study was to evaluate the influence of a therapeutic education program on the quality of life of patients with bipolar disorder (type 1 or 2).

METHOD

This study included 18 patients with bipolar disorder (type 1 or 2) following the therapeutic education program on bipolar disorder which includes 8 sessions of 2hours each. The assessment of quality of life and mood, self-esteem, insight and global functioning was performed before and after the program using the following tools: World Health Organization Quality Of Life questionnaire in short version (WHOQOL-Bref), Hamilton Depression Rating Scale, Young Mania Rating Scale, Rosenberg Self-Esteem Scale, Birchwood Insight Scale and Global Assessment of Functioning Scale. The total score of WHOQOL-Bref constitutes the primary study outcome. The under-scores of WHOQOL-Bref as insight, self-esteem, functioning, depression and mania scores constitute secondary outcomes.

RESULTS

Our results show an improvement in quality of life, regarding global and main dimension scores of WHOQOL-Bref. The mean total scores for quality of life at the beginning and the end of the program were respectively 55.47/100 (standard deviation=14.11) and 60.03/100 (standard deviation=12.62). However, the difference was still not significant even after statistical adjustment with depression, mania and functioning scores. Self-esteem was significantly improved (P=0.0469). Quality of life and self-esteem evolutions were strongly related (correlation coefficient=0.80, P=0.0006). At the end of the program, the less depressed the patients were, the better their quality of life was (correlation coefficient=0.67, P=0.0090). We did not find any correlation between quality of life and mania intensity or global functioning level at the end of the program.

CONCLUSION

This study suggests a need to focus on self-esteem perception in order to understand and ameliorate the quality of life of patients with bipolar disorders. Going further, the use of bipolar disorder specific scales to assess quality of life would be more relevant.

Online psycho-education to the treatment of bipolar disorder: protocol of a randomized controlled trial

BACKGROUND

Bipolar disorder patients frequently present recurrent episodes and often experience subsyndromal symptoms, cognitive impairment and difficulties in functioning, with a low quality of life, illness relapses and recurrent hospitalization. Early diagnosis and appropriate intervention may play a role in preventing neuroprogression in this disorder. New technologies represent an opportunity to develop standardized psychological treatments using internet-based tools that overcome some of the limitations of face-to-face treatments, in that they are readily accessible and the timing of therapy can be tailored to user needs and availability. However, although many psychological programs are offered through the web and mobile devices for bipolar disorder, there is a lack of high quality evidence concerning their efficacy and effectiveness due to the great variability in measures and methodology used.

METHODS

This clinical trial is a simple-blind randomized trial within a European project to compare an internet-based intervention with treatment as usual. Bipolar disorder patients are to be included and randomly assigned to one of two groups: 1) the experimental group (tele-care support) and 2) the control group. Participants in both groups will be evaluated at baseline (pre-treatment) and post-treatment.

DISCUSSION

This study describes the design of a clinical trial based on psychoeducation intervention that may have a significant impact on both prognosis and treatment in bipolar disorder. Specifically, bringing different services together (service aggregation), it is hoped that the approach proposed will significantly increase the impact of information and communication technologies on access and adherence to treatment, quality of the service, patient safety, patient and professional satisfaction, and quality of life of patients.

Empirically supported psychosocial interventions for bipolar disorder: Current state of the research

OBJECTIVES

Bipolar disorder requires psychiatric medications, but even guideline-concordant treatment fails to bring many patients to remission or keep them euthymic. To address this gap, researchers have developed adjunctive psychotherapies. The purpose of this paper is to critically review the evidence for the efficacy of manualized psychosocial interventions for bipolar disorder.

METHODS

We conducted a search of the literature to examine recent (2007-present), randomized controlled studies of the following psychotherapy interventions for bipolar disorder: psychoeducation (PE), cognitive behavioral therapy (CBT), interpersonal and social rhythm therapy (IPSRT), dialectical behavior therapy (DBT), mindfulness-based cognitive therapy (MBCT), and family therapies such as family focused therapy (FFT).

RESULTS

All of the psychotherapy interventions appear to be effective in reducing depressive symptoms. Psychoeducation and CBT are associated with increased time to mood episode relapse or recurrence. MBCT has demonstrated a particular effectiveness in improving depressive and anxiety symptoms. Online psychotherapy interventions, programs combining one or more psychotherapy interventions, and targeted interventions centering on particular symptoms have been the focus of recent, randomized controlled studies in bipolar disorder.

CONCLUSIONS

Psychotherapy interventions for the treatment of bipolar disorder have substantial evidence for efficacy. The next challenge will to disseminate these psychotherapies into the community.

Efficacité d’une démarche de psychoéducation sur l’insight de patients bipolaires I résistants

Le trouble bipolaire est une maladie chronique gravement invalidante pour laquelle le traitement médicamenteux, qui repose sur la prescription de thymorégulateurs, est indispensable. L’objectif principal de tout soignant est d’augmenter l’adhésion aux traitements et que l’observance aux thymorégulateurs soit la meilleure possible. Le temps nécessaire à l’acceptation du trouble est très individuel et peut demander plusieurs années. Les démarches psychoéducatives, apparues il y a tout juste 30 ans visent à augmenter les connaissances sur la maladie, les traitements pharmacologiques et psychologiques et permet l’identification des conséquences du trouble ainsi que l’apprentissage de moyens pour y faire face. Des travaux récents suggèrent que le niveau d’insight de la maladie permettrait de prédire le profit que tire le patient d’une démarche psychoéducative sur la maladie, dans le sens où les patients qui ont un meilleur insight augmenteraient davantage leurs connaissances sur leur maladie et les traitements que les autres. Mieux connaître sa maladie permettrait de mieux gérer ses traitements médicamenteux et psychologiques et aiderait à réduire le taux de rechutes et les conséquences psychosociales. Il s’agit d’évaluer l’efficacité d’une démarche de psychoéducation sur l’acceptation du trouble de 32 patients bipolaires de type I résistants. Tous ont participé à 8 séances de psychoéducation issues d’un programme TCC long en 20 séances selon le programme de Lam, qui constitue l’une des références internationales pour le trouble bipolaire. Chaque patient a été évalué avant et après les 8 séances de psychoéducation à l’aide des questionnaires suivants : la Mood Disorder Insight Scale (MDIS) (Sturman et Sproule, 2003), « Tester ses connaissances du trouble bipolaire » (Basco, 2008), « Évaluation des connaissances de base sur les troubles bipolaires » (Bauer et Mc Bride, 1996). Notre hypothèse est que la psychoéducation permettrait aux patients bipolaires d’accéder à une meilleure acceptation du trouble. Les résultats seront présentés et discutés.

Predictors of functional outcome after a manic episode

BACKGROUND

The identification of functional outcome predictors after acute episodes of bipolar disorders (BD) may allow designing appropriate treatment aiming at restoring psychosocial functioning. Our objective was to identify the best functional outcome predictors at a 6-month follow-up after an index manic episode.

METHODS

We conducted a naturalistic trial (MANACOR) focusing on the global burden of BD, with special emphasis on manic episode-associated costs. We observed patients with BD seen in services of four hospitals in Catalonia (Spain).The total sample included 169 patients with chronic DSM-IV-TR BD I suffering from an acute manic episode who were followed-up for 6 months. In this subanalysis we report the results of a stepwise multiple regression conducted by entering in the model those clinical and sociodemographic variables that were identified through preliminary bivariate Pearson correlations and using total scores on the Functioning Assessment Short Test (FAST) at the 6-month follow-up as the dependent variable.

RESULTS

Number of previous depressive episodes (Beta=3.25; t=3.23; p=0.002), presence of psychotic symptoms during the manic index episode (Beta=7.007; t=2.2; p=0.031) and the Body Mass Index (BMI) at baseline (Beta=0.62; t=2.09; p=0.041) were best predictors of functional outcome after a manic episode.

LIMITATIONS

The main limitations of this study include the retrospective assessment of the episodes, which can be a source of bias, and the 6-month follow-up might have been too short for assessing the course of a chronic illness.

CONCLUSIONS

Psychotic symptoms at index episode, number of past depressive episodes, and BMI predict worse outcome after 6 months follow-up after a manic episode, and may constitute the target of specific treatment strategies.

Assessment of implicit self-esteem in bipolar manic and euthymic patients using the implicit association test

OBJECTIVE

Although self-esteem is thought to be an important psychological factor in bipolar disorder, little is known about implicit and explicit self-esteem in manic patients. In this study, we investigated differences in implicit and explicit self-esteem among bipolar manic patients, bipolar euthymic patients, and healthy controls using the Implicit Association Test (IAT).

METHODS

Participants included 19 manic patients, 27 euthymic patients, and 27 healthy controls. Participants completed a self-esteem scale to evaluate explicit self-esteem and performed the self-esteem IAT to evaluate implicit self-esteem.

RESULTS

There were no differences among groups in explicit self-esteem. However, there were significant differences among groups in implicit self-esteem. Manic patients had higher IAT scores than euthymic patients and a trend toward higher IAT scores than healthy controls.

CONCLUSIONS

Our findings suggest that, on the latent level, a manic state is not simply the opposite of a depressed state. Furthermore, there may be a discontinuity of implicit self-esteem between manic and euthymic states. These unexpected results may be due to characteristics of the study participants or the methods used to assess implicit self-esteem. Nevertheless, they provide greater insights on the psychological status of manic patients.

The progression of 102 Brazilian patients with bipolar disorder: outcome of first 12 months of prospective follow-up

INTRODUCTION

Prospective studies have shown that the course of bipolar disorder (BD) is characterized by the persistence of symptoms, predominantly depression, along most of the time. However, to our knowledge, no studies in Latin America have investigated it.

OBJECTIVES

To replicate international studies using a Brazilian sample to prospectively analyze treatment outcomes in the first year and to determine potential chronicity factors.

METHODS

We followed up 102 patients with BD for 12 months and evaluated the number of months with affective episodes and the intensity of manic and depressive symptoms using the Young Mania Rating Scale (YMRS) and the Hamilton Depression Scale (HAM-D17). Sociodemographic and retrospective clinical data were examined to determine possible predictors of outcome.

RESULTS

Almost 50% of the patients had symptoms about half of the time, and there was a predominance of depressive episodes. Disease duration and number of depressive episodes were predictors of chronicity. Depressive polarity of the first episode and a higher number of depressive episodes predicted the occurrence of new depressive episodes.

CONCLUSION

In general, BD outcome seems to be poor in the first year of monitoring, despite adequate treatment. There is a predominance of depressive symptoms, and previous depressive episodes are a predictor of new depressive episodes and worse outcome.

Pilot study of the efficacy of double-blind, placebo-controlled one-week olanzapine stabilization therapy in heterogeneous symptomatic bipolar disorder patients

BACKGROUND

Olanzapine has demonstrated efficacy in acute mania and bipolar I disorder (BDI) maintenance, but efficacy in brief therapy in more diverse populations, including patients with bipolar II disorder (BDII)/bipolar disorder not otherwise specified (BDNOS) with syndromal/subsyndromal depressive/mood elevation symptoms and taking/not taking concurrent medications remains to be established.

METHODS

Fifty adult outpatients (24 BD1, 22 BDII, 4 BDNOS, mean ± SD age 40.8 ± 11.5 years, 28.1% female, already taking 1.1 ± 1.2 [median 1] prescription psychotropics) with 17-item Hamilton Depression Rating Scale (HDRS) ≥10 and/or Young Mania Rating Scale (YMRS) ≥10 and ≤24, were randomized to double-blind olanzapine (2.5-20 mg/day) versus placebo for one week.

RESULTS

Among 45 patients with post-baseline ratings, olanzapine (9.0 ± 5.8 mg/day, n = 23) compared to placebo (n = 22) tended to yield greater Clinical Global Impressions-Bipolar Version-Overall Severity of Illness (-1.4 ± 0.9 versus -0.8 ± 1.1, p = 0.08) and Hamilton Anxiety Scale (-7.9 ± 6.3 versus -3.8 ± 6.1, p = 0.07) improvements, and YMRS/HDRS remission rate (47.8% versus 22.7%, p = 0.08), but significantly increased median weight (+2 versus -1 lbs, p = 0.001), and rates of excessive appetite (54.2% versus 22.7%, p = 0.04) and tremor (50.0% versus 9.1% p = 0.004). Number Needed to Treat and 95% Confidence Interval for YMRS/HDRS remission were 4 (1-∞). Numbers Needed to Harm for excessive appetite and tremor were 4 (1-21) and 3 (1-6), respectively.

CONCLUSIONS

Olanzapine tended to yield affective improvement and significantly increased weight, appetite, and tremor. Larger controlled studies appear feasible and warranted to assess brief olanzapine therapy in heterogeneous symptomatic bipolar disorder patients.

Self-referential thinking, suicide, and function of the cortical midline structures and striatum in mood disorders: possible implications for treatment studies of mindfulness-based interventions for bipolar depression

Bipolar depression is often refractory to treatment and is frequently associated with anxiety symptoms and elevated suicide risk. There is a great need for adjunctive psychotherapeutic interventions. Treatments with effectiveness for depressive and anxiety symptoms as well as suicide-related thoughts and behaviors would be particularly beneficial. Mindfulness-based interventions hold promise, and studies of these approaches for bipolar disorder are warranted. The aim of this paper is to provide a conceptual background for such studies by reviewing key findings from diverse lines of investigation. Results of that review indicate that cortical midline structures (CMS) appear to link abnormal self-referential thinking to emotional dysregulation in mood disorders. Furthermore, CMS and striatal dysfunction may play a role in the neuropathology underlying suicide-related thoughts and behaviors. Thus, combining studies of mindfulness interventions targeting abnormal self-referential thinking with functional imaging of CMS and striatal function may help delineate the neurobiological mechanisms of action of these treatments.
