New Treatment Approaches

• New Treatment Approaches

2
Treating Acute Bipolar Depression

• Great need still exists for evidence-based
  approaches to this common clinical problem
• Limited data support traditional antidepressants
  as monotherapy
• Positive data in clinical trials for OFC and
  quetiapine
• Clinicians need effectiveness trials to explore
  the common practice of polypharmacy for acute
  bipolar depression

3
Evidence Based Therapies

• Impact relapse and rehospitalization rates
• Group psychoeducation
• 25 hospitalized vs 35 in unstructured group1
• Cognitive behavioral therapy (CBT)
• 1 year relapse 44 vs 75 usual care2
• Family focused treatment (FFT)
• 2 year relapse 28 with FFT vs 60 unsupportive3
• Perceived criticism may be an indicator4

Interpersonal Social Rhythm Therapy

• RCT, IPSRT vs ICM, n 175 BP1, 2 years
• Effect size of .58
• After controlling marital status, index polarity,
  anxiety, medical burden
• Mediated by improved social rhythms
• Not adherence
• Better if married
• Best initiated in early maintenance
• ICM better if medically ill and anxious
• Intensive clinical management

Lithium Meta-analysis

• Five RCTs, Li vs placebo, n 770
• One relapse prevented for every 14 patients
  treated 12 years
• One mania for every 10 patients
• One depression for every 14 patients

Treatment of Bipolar Depression

• Fewer studies than for mania
• Limited approved treatments
• Traditional antidepressants lack evidence and may
  cause mood destabilization

Bipolar Depression and Antidepressants General
Guidelines and Risks

• Always use mood stabilizer in bipolar I patients,
  even while depressed
• Promptly wean the antidepressant if evidence of
  hypomania or mania emerges
• Antidepressants may trigger mania (mood
  destabilization) or accelerate mood cycle
• Up to 33 of patients with bipolar disorder may
  be susceptible to antidepressant-induced manias
• Possibly less efficacious in BP than UP
  depression
• Few standard antidepressants have been studied in
  bipolar depression

General Principles

• Maintenance
• Continue effective acute phase treatment(s) or
  
• Switch to one with evidence of maintenance
• efficacy
• Varies by polarity of most recent episode
• Simplify medication regimen
• Improve tolerability and adherence
• Little data on combinations in maintenance

Summary

• Evidence-based treatment for bipolar depression
  includes lithium and lamotrigine
• Quetiapine and OFC are emerging as viable
  alternatives for bipolar depression
• Monotherapy standard antidepressants may cause
  problems in terms of mood destabilization in
  bipolar depression
• Using antidepressants in bipolar depression is
  better than nothing, but not better than using
  lithium or a mood stabilizer
• Some novel antipsychotics may have a role in
  treating bipolar depression as monotherapy while
  stabilizing mania
• Goal is to stabilize depression without causing
  mania and minimizing side effects
