Progressing MoodSwings. The upgrade and evaluation of MoodSwings 2.0: An online intervention for bipolar disorder.

MoodSwings 2.0 is a self-guided online intervention for bipolar disorder. The intervention incorporates technological improvements on an earlier validated version of the intervention (MoodSwings 1.0). The previous MoodSwings trial provides this study with a unique opportunity to progress previous work, whilst being able to take into consideration lesson learnt, and technological enhancements. The structure and technology of MoodSwings 2.0 are described and the relevance to other online health interventions is highlighted. An international team from Australia and the US updated and improved the programs content pursuant to changes in DSM-5, added multimedia components and included larger numbers of participants in the group discussion boards. Greater methodological rigour in this trial includes an attention control condition, quarterly telephone assessments, and red flag alerts for significant clinical change. This paper outlines these improvements, including additional security and safety measures. A 3 arm RCT is currently evaluating the enhanced program to assess the efficacy of MS 2.0; the primary outcome is change in depressive and manic symptoms. To our knowledge this is the first randomized controlled online bipolar study with a discussion board attention control and meets the key methodological criteria for online interventions.

More pernicious course of bipolar disorder in the United States than in many European countries: implications for policy and treatment.

BACKGROUND: There is some controversy but growing evidence that childhood onset bipolar disorder may be more prevalent and run a more difficult course in the United States than some European countries. METHODS: We update and synthesize course of illness data from more than 960 outpatients with bipolar disorder (average age 40) from 4 sites in the U.S. and 3 sites in Netherlands and Germany. After giving informed consent, patients reported on parental history, childhood and lifetime stressors, comorbidities, and illness characteristics. RESULTS: Almost all aspects of bipolar disorder were more adverse in patients from the US compared with Europe, including a significantly higher prevalence of: bipolar disorder in one parent and a mood disorder in both parents; childhood verbal, physical, or sexual abuse; stressors in the year prior to illness onset and the last episode; childhood onsets of bipolar illness; delay to first treatment; anxiety disorder, substance abuse, and medical comorbidity; mood episodes and rapid cycling; and nonresponse to prospective naturalistic treatment. LIMITATIONS: Selection bias in the recruit of patients cannot be ruled out, but convergent data in the literature suggest that this does not account for the findings. Potential mechanisms for the early onset and more adverse course in the U.S. have not been adequately delineated and require further investigation. CONCLUSIONS: The data suggest the need for earlier and more effective long-term treatment intervention in an attempt to ameliorate this adverse course and its associated heavy burden of psychiatric and medical morbidity.

Increased parental history of bipolar disorder in the United States: association with early age of onset.

OBJECTIVE: Early-onset bipolar (BP) disorder and other poor prognosis characteristics are more prevalent in patients from the United States than from the Netherlands and Germany (abbreviated as Europe). We explored the impact of parental loading for affective illness on onset and other characteristics of BP disorder. METHOD: Parental history for unipolar (UP) and bipolar (BP) depression and course of illness characteristics were obtained from self-report in adults (average age 42) with BP disorder. Illness characteristics were examined by χ2 and multinomial logistic regression in relationship to the degree of parental loading: i) both parents negative; ii) one UP disorder; iii) one with BP disorder; and iv) both affected. RESULTS: After controlling for many poor prognosis factors, compared with those from Europe, patients from the United States had more iii) one parent with BP disorder and iv) both parents affected. An early age of onset of BP disorder was independently associated with this increased parental loading for affective disorder. CONCLUSION: Parental history of BP disorder and both parents with a mood disorder were more common in the United States than Europe and were associated with an early onset of bipolar disorder and other poor prognosis characteristics. These findings deserve replication and exploration of the potential mechanisms involved and their therapeutic implications.

Comparison of objective and subjective assessments of sleep time in subjects with bipolar disorder.

INTRODUCTION: Sleep disturbance is a core feature of bipolar disorder. To date there are a limited number of studies that compare subjective and objective measures of sleep in populations of subjects with mood disorders. This study evaluated the relationship between subjective and objective measurements of total sleep time (TST) in a bipolar type I disorder (BD I) population. METHODS: Thirty-nine subjects diagnosed with BD I participated in the study. Mood symptoms were assessed via YMRS and IDS-30-C. Subjects wore an actigraph device and maintained a sleep diary for seven consecutive days. Differences between TST as estimated via sleep diaries and actigraphy were calculated. RESULTS: Objective and subjective measures of TST were significantly correlated (r=0.5151, p=0.0008). Secondary analysis revealed that the severity of depressive symptoms did correlate to this discrepancy (t=2.65, p=0.01). LIMITATIONS: The impact that medications have on the accuracy of TST reported was not investigated. Also, sleep diaries may have acted to prompt subjects to pay closer attention to their sleep habits and therefore more accurately report TST than in the average clinical setting. CONCLUSION: The results of the current study demonstrate a significant correlation between the estimation of TST as measured objectively via actigraphy and subjectively via sleep diaries in BD patients. Mood symptomotology might impact the accuracy of TST reported. Further study is warranted.

Characteristics of responders and non-responders to risperidone monotherapy or placebo in co-occurring bipolar disorder and anxiety disorder.

Clinical characteristics predicting response and remission to psychopharmacological treatment of bipolar disorder (BD) and co-occurring anxiety disorders have been understudied. We hypothesized that non-response to risperidone or placebo in individuals with co-occurring BD and anxiety symptoms would be associated with a more severe clinical course of BD, and certain demographic variables. This study was a secondary analysis of a randomized, double-blind, parallel, 8-week study comparing risperidone monotherapy and placebo in individuals with BD plus current panic disorder, current generalized anxiety disorder (GAD), or lifetime panic disorder (n=111) [31]. We compared clinical characteristics of responders (50% improvement on the Hamilton Anxiety Scale [HAM-A]) and non-responders as well as remitters (HAM-A<7) and non-remitters in risperidone treatment (n=54) and placebo (n=57) groups. For non-responders in the risperidone group, co-occurring lifetime panic disorder was significantly more common than for non-responders in the placebo group. Apart from this, no significant differences in course of illness or demographics were found either between or across groups for patients with BD and co-occurring anxiety symptoms receiving risperidone or placebo in this acute phase study.

Depressive relapse during lithium treatment associated with increased serum thyroid-stimulating hormone: results from two placebo-controlled bipolar I maintenance studies.

OBJECTIVE: To assess the relationship between depressive relapse and change in thyroid function in an exploratory post hoc analysis from a controlled maintenance evaluation of bipolar I disorder. METHOD: Mean thyroid-stimulating hormone (TSH) and outcome data were pooled from two 18-month, double-blind, placebo-controlled, maintenance studies of lamotrigine and lithium monotherapy. A post hoc analysis of 109 subjects (n = 55 lamotrigine, n = 32 lithium, n = 22 placebo) with serum TSH values at screening and either week 52 (+/-14 days) or study drop-out was conducted. RESULTS: Lithium-treated subjects who required an intervention for a depressive episode had a significantly higher adjusted mean TSH level (4.4 microIU/ml) compared with lithium-treated subjects who did not require intervention for a depressive episode (2.4 microIU/ml). CONCLUSION: Lithium-related changes in thyroid function are clinically relevant and should be carefully monitored in the maintenance phase of bipolar disorder to maximize mood stability and minimize the risk of subsyndromal or syndromal depressive relapse.

Tranylcypromine vs. lamotrigine in the treatment of refractory bipolar depression: a failed but clinically useful study.

OBJECTIVE: To compare the efficacy and tolerability of tranylcypromine vs. lamotrigine in bipolar depression not responding to conventional antidepressants. METHOD: Bipolar depressed patients received open randomized treatment with tranylcypromine or lamotrigine as add-on to a mood stabilizer during 10 weeks. In a second treatment phase, non-responding patients could receive the opposite drug. Outcome criteria were response (measured with CGI-BP and IDS-C), switch into mania, and completion of the study. RESULTS: Only 20 of 70 planned patients were randomized, due to problems with recruitment, and 19 patients received any medication. During the first treatment phase 5/8 patients (62.5%) responded to tranylcypromine without switch into mania, compared with 4/11 patients (36.4%) on lamotrigine with two switches (statistically not significant). Over both treatment phases, 8/10 patients (80%) receiving tranylcypromine completed the study vs. 5/13 (38.5%) on lamotrigine (likelihood 0.02). CONCLUSION: There still appears to be a role for tranylcypromine in the treatment of refractory bipolar depression. Larger controlled studies are demanded.

Mood switch in bipolar depression: comparison of adjunctive venlafaxine, bupropion and sertraline.

BACKGROUND: Few studies have examined the relative risks of switching into hypomania or mania associated with second-generation antidepressant drugs in bipolar depression. AIMS: To examine the relative acute effects of bupropion, sertraline and venlafaxine as adjuncts to mood stabilisers. METHOD: In a 10-week trial, participants receiving out-patient treatment for bipolar disorder (stratified for rapid cycling) were randomly treated with a flexible dose of one of the antidepressants, or their respective matching placebos, as adjuncts to mood stabilisers. RESULTS: A total of 174 adults with bipolar disorder I, II or not otherwise specified, currently in the depressed phase, were included. All three antidepressants were associated with a similar range of acute response (49-53%) and remission (34-41%). There was a significantly increased risk of switches into hypomania or mania in participants treated with venlafaxine compared with bupropion or sertraline. CONCLUSIONS: More caution appears indicated in the use of venlafaxine rather than bupropion or sertraline in the adjunctive treatment of bipolar depression, especially if there is a prior history of rapid cycling.

Quetiapine with lithium or divalproex for the treatment of bipolar mania: a randomized, double-blind, placebo-controlled study.

OBJECTIVE: Evaluate the efficacy and tolerability of quetiapine (QTP) combined with lithium (Li) or divalproex (DVP) in the treatment of acute mania. METHODS: Patients were randomized to 21 days of double-blind treatment with QTP plus Li/DVP, or placebo (PBO) plus Li/DVP. QTP was rapidly dosed up to a maximum of 800 mg/day; Li was dosed to 0.7-1.0 mEq/L; or DVP to 50-100 microg/mL. RESULTS: Fifty-six of 91 (61.5%) individuals in the QTP + Li/DVP group compared with 49 of 100 (49%) taking PBO + Li/DVP completed the study. A significantly greater mean reduction in total Young Mania Rating Scale (YMRS) score was observed at end-point in patients receiving QTP + Li/DVP compared with those in the PBO + Li/DVP group (-13.76 versus -9.93; p = 0.021). The response rate (> or =50% YMRS improvement) was significantly higher in the QTP + Li/DVP group than in PBO + Li/DVP-treated patients (54.3% versus 32.6%; p = 0.005), as was the proportion of patients achieving clinical remission (YMRS < 12) (45.7% versus 25.8%; p = 0.007). Patients receiving QTP + Li/DVP also had a significantly greater improvement in Clinical Global Impressions-Bipolar (CGI-BP) Severity of Illness scores (-1.38 versus -0.78; p = 0.001). The mean last-week dose of QTP was 584 mg/day in patients meeting response criteria. Common adverse events (at least 10% and twice the rate of Li/DVP) in the QTP + Li/DVP group included somnolence, dry mouth, asthenia, and postural hypotension. CONCLUSIONS: Quetiapine combined with either Li or DVP has superior efficacy compared with Li or DVP monotherapy for treating patients with bipolar mania. Combination therapy was well-tolerated and most adverse events were mild, withdrawal because of adverse events being only 5% compared with 6% on Li or DVP monotherapy.

Use of quetiapine in bipolar disorder: a case series with prospective evaluation.

Quetiapine, a new atypical antipsychotic, was added to ongoing treatment of bipolar I outpatients (n=15) for symptoms of illness (mood lability, irritability, psychosis and/or difficulty sleeping). All evaluations were prospectively obtained, with the majority of patients (n=9) showing much or very much improvement on the Clinical Global Impression for Bipolar Disorder (CGI-BP). Somatic complaints were limited. Mean (SD) duration before changes in medication regimens was 134 (100) days. Studies of the use of quetiapine in maintenance treatment of bipolar disorder are warranted.

The Inventory of Depressive Symptomatology, Clinician Rating (IDS-C) and Self-Report (IDS-SR), and the Quick Inventory of Depressive Symptomatology, Clinician Rating (QIDS-C) and Self-Report (QIDS-SR) in public sector patients with mood disorders: a psychometric evaluation.

BACKGROUND: The present study provides additional data on the psychometric properties of the 30-item Inventory of Depressive Symptomatology (IDS) and of the recently developed Quick Inventory of Depressive Symptomatology (QIDS), a brief 16-item symptom severity rating scale that was derived from the longer form. Both the IDS and QIDS are available in matched clinician-rated (IDS-C30; QIDS-C16) and self-report (IDS-SR30; QIDS-SR16) formats. METHOD: The patient samples included 544 out-patients with major depressive disorder (MDD) and 402 out-patients with bipolar disorder (BD) drawn from 19 regionally and ethnicically diverse clinics as part of the Texas Medication Algorithm Project (TMAP). Psychometric analyses including sensitivity to change with treatment were conducted. RESULTS: Internal consistencies (Cronbach's alpha) ranged from 0.81 to 0.94 for all four scales (QIDS-C16, QIDS-SR16, IDS-C30 and IDS-SR30) in both MDD and BD patients. Sad mood, involvement, energy, concentration and self-outlook had the highest item-total correlations among patients with MDD and BD across all four scales. QIDS-SR16 and IDS-SR30 total scores were highly correlated among patients with MDD at exit (c = 0.83). QIDS-C16 and IDS-C30 total scores were also highly correlated among patients with MDD (c = 0.82) and patients with BD (c = 0.81). The IDS-SR30, IDS-C30, QIDS-SR16, and QIDS-C16 were equivalently sensitive to symptom change, indicating high concurrent validity for all four scales. High concurrent validity was also documented based on the SF-12 Mental Health Summary score for the population divided in quintiles based on their IDS or QIDS score. CONCLUSION: The QIDS-SR16 and QIDS-C16, as well as the longer 30-item versions, have highly acceptable psychometric properties and are treatment sensitive measures of symptom severity in depression.

The Stanley Foundation Bipolar Network. I. Rationale and methods.

BACKGROUND: The Stanley Foundation Bipolar Network (SFBN) was created to address the paucity of help studies in bipolar illness. AIMS: To describe the rationale and methods of the SFBN. METHOD: The SFBN includes five core sites and a number of affiliated sites that have adopted consistent methodology for continuous longitudinal monitoring of patients. Open and controlled studies are performed as patients' symptomatology dictates. RESULTS: The reliability of SFBN raters and the validity of the rating instruments have been established. More than 500 patients are in continuous daily longitudinal follow-up. More than 125 have been randomised to one of three of the newer antidepressants (bupropion, sertraline and venlafaxine) as adjuncts in a study of mood stabilizers and 93 to omega-3 fatty acids. A number of open clinical case series have been published. CONCLUSIONS: Well-characterised patients are followed in a detailed continuous longitudinal fashion in both opportunistic case series and double-blind, randomised controlled trials with reliable and validated measures.

The Stanley Foundation Bipolar Network. 2. Preliminary summary of demographics, course of illness and response to novel treatments.

BACKGROUND: The Stanley Foundation Bipolar Network (SFBN) evaluates treatments, course and clinical and neurobiological markers of response in bipolar illness. AIMS: To give a preliminary summary of emerging findings in these areas. METHOD: Studies with established and potentially antimanic, antidepressant and mood-stabilising agents range from open case series to double-blind randomised clinical trials, and use the same core assessment methodology, thereby optimising the comparability of the outcomes. The National Institute of Mental Health Life Chart Method is the core instrument for retrospective and prospective longitudinal illness description. RESULTS: The first groups of patients enrolled show a considerable degree of past and present symptomatology, psychiatric comorbidity and functional impairment. There are associations of both genetic and early environmental factors with more severe courses of illness. Open case series with add-on olanzapine, lamotrigine, gabapentin or topiramate show a differential spectrum of effectiveness in refractory patients. CONCLUSIONS: The SFBN provides important new data for the understanding and treatment of bipolar disorder.

Texas Medication Algorithm Project: development and feasibility testing of a treatment algorithm for patients with bipolar disorder.

BACKGROUND: Use of treatment guidelines for treatment of major psychiatric illnesses has increased in recent years. The Texas Medication Algorithm Project (TMAP) was developed to study the feasibility and process of developing and implementing guidelines for bipolar disorder, major depressive disorder, and schizophrenia in the public mental health system of Texas. This article describes the consensus process used to develop the first set of TMAP algorithms for the Bipolar Disorder Module (Phase 1) and the trial testing the feasibility of their implementation in inpatient and outpatient psychiatric settings across Texas (Phase 2). METHOD: The feasibility trial answered core questions regarding implementation of treatment guidelines for bipolar disorder. A total of 69 patients were treated with the original algorithms for bipolar disorder developed in Phase 1 of TMAP. RESULTS: Results support that physicians accepted the guidelines, followed recommendations to see patients at certain intervals, and utilized sequenced treatment steps differentially over the course of treatment. While improvements in clinical symptoms (24-item Brief Psychiatric Rating Scale) were observed over the course of enrollment in the trial, these conclusions are limited by the fact that physician volunteers were utilized for both treatment and ratings. and there was no control group. CONCLUSION: Results from Phases 1 and 2 indicate that it is possible to develop and implement a treatment guideline for patients with a history of mania in public mental health clinics in Texas. TMAP Phase 3, a recently completed larger and controlled trial assessing the clinical and economic impact of treatment guidelines and patient and family education in the public mental health system of Texas, improves upon this methodology.

Bipolar rapid cycling: focus on depression as its hallmark.

The phenomenon of frequent cycling in bipolar disorder was first recognized by Emil Kraepelin in 1913. More recently, rapid cycling has been reported to be a predictor of nonresponse to treatment. At the time of presentation, most patients with DSM-IV-defined rapid cycling appear to be in the depressed phase of their illness. Frequent and more severe episodes of depression appear to be the hallmark of rapid cycling. Reported in this article are recent preliminary data suggesting that the combination of lithium and divalproex sodium administered continuously over 6 months appears to result in marked acute and continuation antimanic efficacy in 85% of patients and marked antidepressant efficacy in 60%. However, only one half of patients experienced bimodal stabilization. Comorbid alcohol, cannabis, and/or cocaine abuse and/or dependence did not appear to directly affect the spectrum of efficacy of lithium and divalproex or response rates in compliant patients. Comorbidity appeared to alter prognosis by increasing the prevalence of poor compliance. The majority of patients receiving lithium and divalproex who required additional treatment were depressed, suggesting that the frequent recurrence of depression is the primary unmet need in patients with rapid cycling. The use of antidepressants in this population has been discouraged because of concerns about the possibility of cycle acceleration. There exists a need for a pharmacotherapy that not only possesses marked acute antidepressant properties, but that does so without inducing switching or cycle acceleration. A double-blind, placebo-controlled trial of lamotrigine monotherapy in bipolar I depression has demonstrated efficacy without causing switching at a rate exceeding placebo; however, this initial study excluded patients with rapid cycling. To explore the efficacy of lamotrigine in rapid cycling, a recent multicenter study has examined lamotrigine as a maintenance therapy for this population. The results indicate that lamotrigine may be a useful treatment for patients with rapid-cycling bipolar II disorder and that this drug has begun to address this unmet need.

Drug abuse and bipolar disorder: comorbidity or misdiagnosis?

Bipolar disorder is a common, severe and cyclic psychiatric illness. A strong association between alcohol dependence and bipolar disorder has been reported in numerous studies. The abuse of other drugs including cocaine, amphetamines, opiates, cannabis, and prescription medications in bipolar patients is also an important public health concern and has been less extensively investigated. This review examines the abuse of drugs other than alcohol or nicotine in people with bipolar disorder. The high rates of milder affective symptoms but not mania observed in patients in drug abuse treatment settings suggests the symptoms may in many cases be associated with the drug use. However, such patients presenting in psychiatric settings might be suffering from cyclothymic and related attenuated bipolar disorders (type II). Substance abuse may be associated with medication non-compliance, more mixed or dysphoric mania and possibly an earlier onset of affective symptoms and more hospitalizations. The pharmacotherapy of patients with bipolar disorder and drug abuse is examined, including evidence on the use of mood stabilizers, neuroleptics and the newer atypical antipsychotics in this population.

Axis I psychiatric comorbidity and its relationship to historical illness variables in 288 patients with bipolar disorder.

OBJECTIVE: Bipolar disorder often co-occurs with other axis I disorders, but little is known about the relationships between the clinical features of bipolar illness and these comorbid conditions. Therefore, the authors assessed comorbid lifetime and current axis I disorders in 288 patients with bipolar disorder and the relationships of these comorbid disorders to selected demographic and historical illness variables. METHOD: They evaluated 288 outpatients with bipolar I or II disorder, using structured diagnostic interviews and clinician-administered and self-rated questionnaires to determine the diagnosis of bipolar disorder, comorbid axis I disorder diagnoses, and demographic and historical illness characteristics. RESULTS: One hundred eighty-seven (65%) of the patients with bipolar disorder also met DSM-IV criteria for at least one comorbid lifetime axis I disorder. More patients had comorbid anxiety disorders (N=78, 42%) and substance use disorders (N=78, 42%) than had eating disorders (N=9, 5%). There were no differences in comorbidity between patients with bipolar I and bipolar II disorder. Both lifetime axis I comorbidity and current axis I comorbidity were associated with earlier age at onset of affective symptoms and syndromal bipolar disorder. Current axis I comorbidity was associated with a history of development of both cycle acceleration and more severe episodes over time. CONCLUSIONS: Patients with bipolar disorder often have comorbid anxiety, substance use, and, to a lesser extent, eating disorders. Moreover, axis I comorbidity, especially current comorbidity, may be associated with an earlier age at onset and worsening course of bipolar illness. Further research into the prognostic and treatment response implications of axis I comorbidity in bipolar disorder is important and is in progress.

Psychopharmacologic treatment strategies for depression, bipolar disorder, and schizophrenia.

Patients with serious psychiatric disorders are frequently treated by primary care physicians, who may have difficulty keeping up with recent advances in psychiatry. This paper presents an updated synopsis for three major psychiatric illnesses: major depression, bipolar disorder, and schizophrenia. Current definitions, updated diagnostic criteria, short- and long-term treatment strategies with algorithms, and special challenges for the clinician are discussed for each of these illnesses. On the basis of each illness's distinct characteristics, five treatment principles are emphasized: 1) Treatment strategies should be long-term and should emphasize adherence, 2) treatment choice should be empirical, 3) combinations of medications may be helpful, 4) a combination of psychosocial and pharmacologic treatments may be more useful than either alone, and 5) the family or "significant others" as well as a consumer organization need to be involved. Some of the new directions in dinical research to refine these strategies and meet these challenges are also described.
