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.

[Psychology and psychotherapy in bipolar disorder].

This essay presents recent insights and theories relating to the various psychological mechanisms underlying bipolar disorder and describes a number of the psychotherapies that are based on these mechanisms. Each type of psychotherapy derives from the assumption that bipolar disorder has a neurobiological origin and all the psychotherapies involve long-term pharmacotherapy and comprise many psychoeducational elements. The psychotherapies complement each other and the best and most useful parts of one therapy can be combined with those of others in everyday practice. Patients participating in these psychotherapies can obtain additional support from self help manuals.

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.

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.

Open-label adjunctive topiramate in the treatment of bipolar disorders.

BACKGROUND: To preliminarily explore the spectrum of effectiveness and tolerability of the new antiepileptic drug topiramate in bipolar disorder, we evaluated the response of 56 bipolar outpatients in the Stanley Foundation Bipolar Outcome Network (SFBN) who had been treated with adjunctive topiramate in an open-label, naturalistic fashion. METHODS: In this case series, response to topiramate was assessed every 2 weeks for the first 3 months according to standard ratings in the SFBN, and monthly thereafter while patients remained on topiramate. Patients' weights, body mass indices (BMIs), and side effects were also assessed. RESULTS: Of the 54 patients who completed at least 2 weeks of open-label, add-on topiramate treatment, 30 had manic, mixed, or cycling symptoms, 11 had depressed symptoms, and 13 were relatively euthymic at the time topiramate was begun. Patients who had been initially treated for manic symptoms displayed significant reductions in standard ratings scores after 4 weeks, after 10 weeks, and at the last evaluation. Those patients who were initially depressed or treated while euthymic showed no significant changes. Patients as a group displayed significant decreases in weight and BMI from topiramate initiation to week 4, to week 10, and to the last evaluation. The most common adverse side effects were neurologic and gastrointestinal. CONCLUSIONS: These preliminary open observations of adjunctive topiramate treatment suggest that it may have antimanic or anticycling effects in some patients with bipolar disorder, and may be associated with appetite suppression and weight loss that is often viewed as beneficial by the patient and clinician. Controlled studies of topiramate's acute and long-term efficacy and side effects in bipolar disorder appear warranted.

[Risk of inducing resistance upon stopping and restarting lithium after long-term usage].

Three man, aged 66, 60 and 26 years with bipolar disorder and long periods (20-5 years) of effective lithium prophylaxis had relapses on lithium discontinuation. Once the drug was reinstituted, it was no longer effective. Combinations of lithium with a classical MAO inhibitor or a second mood stabilizer (valproic acid and carbamazepine, respectively) ultimately proved to be successful. The risk of refractoriness should be kept in mind before considering to stop lithium therapy. A better compliance can be achieved by informing patients about the risks of discontinuing lithium, by maintaining a minimal maintenance dose and by adequately coping with possible side effects.
