  1. Answer the question “What to do next?” when acute depression doesn’t respond to monotherapy with a mood stabilizer See if using an antidepressant or non-antidepressant treatment makes a difference in recovery Test the efficacy of psychosocial therapy as an adjunct Overall Goals of the STEP-BD Randomized Clinical Trials Pathway Sachs GS, et al. Biol Psychiatry. 2003;53:1028-1042.

  2. Overview—Randomized Clinical Trials Abbreviations: CBT, cognitive behavioral therapy; CC, Collaborative Care; FFT, family-focused psychoeducational treatment; IPSRT, Interpersonal Social Rhythm Therapy; MS, Mood Stabilizer; TEAS, treatment-emergent affective switch. 1. Sachs GS, et al. N Engl J Med. 2007;356:1711-1722. 2. Nierenberg AA, et al. Am J Psychiatry. 2006;163:210-216. 3. Miklowitz DJ, et al. Arch Gen Psychiatry. 2007;64:419-427.

  3. Advantages of Using Intensive Psychotherapy as an Adjunct • Patients were 1.6 times more likely to be well in any given study month if they received intensive psychotherapy • Patients became well an average of 110 days fasterthan those in collaborative care Miklowitz DJ, et al. Arch Gen Psychiatry. 2007;64:419-427.

  4. Risk Factors that Increase the Chance of Recurrence after Recovery If any of the following happened the year prior to recovery from an acute episode, the risk of recurrence increased: • Previous lifetime episodes >20 • Number of residual symptoms– For every depressive symptom remaining, risk increases by 14%– For every manic symptom remaining, risk increases by 20% • Length of time spent in prior episode (longer = worse) • Length of time with anxiety symptoms (longer = worse) Miklowitz DJ, et al. Arch Gen Psychiatry. 2007;64:419-427.

  5. Recovery and Recurrence in STEP-BD Entered STEP-BD symptomatic Only ~1/4 of the cohort in this study achieved recovery without a relapse in ≤2 years Achieved recovery Recurrence within 2 years 416 41% 858 58% 1469 Perlis RH, et al. Am J Psychiatry. 2006;163:217-224.

  6. Ancillary Anxiety Study in STEP-BD • ANY current anxiety disorder increases the risk of an earlier acute recurrence1 • Presence of anxiety disorder causes, on average, a loss of 39 days being well1 • As the number of anxiety disorders increase, it increases the loss of days being well1 • Anxiety disorders also increase suicide risk2 • In the 239 STEP-BD patients who were tracked for a year in follow-up, 41% of the patients with at least 1 anxiety disorder relapsed1 1. Otto MW, et al. Br J Psychiatry. 2006;189:20-25. 2. Simon NM, et al. J Psychiatr Res. 2007;41:255-264.

  7. Ancillary ADHD Study in STEP-BD • In bipolar children, ADHD co-occurs 60%–90% of the time • This comorbidity has not been studied at length in adults • STEP-BD showed that bipolar adults with ADHD – Have a poorer prognosis with bipolar disorders– Are more symptomatic– Are less likely to recover from mood episodes– Are more likely to have more mania episodes– Are more at risk for other psychiatric comorbidities Nierenberg AA, et al. Biol Psychiatry. 2005;57:1467-1473.

  8. Functional Impairment After Recovery • Followed 103 STEP-BD subjects who had been in remission at least 4 weeks • The Work and Social Adjustment Scale (WSAS) was used to assess overall functional status • Findings: bipolar patients still have substantial functional deficits even during periods of sustained remission (in this cohort, 4 weeks to 13 years) • Degree of functional impairment correlates with degree of residual depressive symptoms (but not panic/mania symptoms) • Patients may benefit from comprehensive psychosocial and rehabilitative interventions Nierenberg AA, et al. Biol Psychiatry. 2005;57:1467-1473.

  9. Take-Away Messages • Despite best efforts, recurring illness is still too common in bipolar disorders • The value of antidepressants as adjunctive therapy in acute bipolar depression has yet to be established • Nonantidepressant adjunctive therapy may have modest benefits in refractory bipolar depression • Intensive psychotherapy has value as perhaps the most useful adjunct to pharmacotherapy in treating bipolar depression • Careful evaluations tracking patient symptoms at recovery can help alter recurrences • The most important single independent predictor of risk was residual, subthreshold mood elevation symptoms Thase ME. Curr Psychiatry Rep. 2007;9:497-503.
