The 2002 American Psychiatric Association (APA) guidelines for the treatment of bipolar disorder recommended more conservative use of antidepressants. This change in comparison with previous APA guidelines has been criticized, especially from some groups in Europe. The Munich group in particular has published a critique of assumptions underlying the conservative recommendations of the recent APA treatment guidelines. In this paper, we re-examine the argument put forward by the Munich group, and we demonstrate that indeed, conceptually and empirically, there is a strong rationale for a cautious approach to antidepressant use in bipolar disorder, consistent with, and perhaps even more strongly than, the APA guidelines. This rationale is based on support for the following four propositions: (i) The risk of antidepressant induced mood-cycling is high, (ii) Antidepressants have not been shown to definitively prevent completed suicides and reduce mortality, whereas lithium has, (iii) Antidepressants have not been shown to be more effective than mood stabilizers in acute bipolar depression and have been shown to be less effective than mood stabilizers in preventing depressive relapse in bipolar disorder and (iv) Mood stabilizers, especially lithium and lamotrigine, have been shown to be effective in acute and prophylactic treatment of bipolar depressive episodes. We therefore draw three conclusions from this interpretation of the evidence: (i) There are significant risks of mania and long-term worsening of bipolar illness with antidepressants, (ii) Antidepressants should generally be reserved for severe cases of acute bipolar depression and not routinely used in mild to moderate cases and (iii) Antidepressants should be discontinued after recovery from the depressive episode, and maintained only in those who repeatedly relapse after antidepressant discontinuation (a minority we judge to represent only about 15-20% of bipolar depressed patients).

Antidepressants of all types showed limited efficacy in juvenile depression, but fluoxetine might be more effective, especially in adolescents. Studies in children and in severely depressed, hospitalised or suicidal juvenile patients are needed, and effective, safe and readily accessible treatments for juvenile depression are urgently required.

We evaluated the long-term antidepressant safety and response of adjunctive pramipexole, a D2-D3 dopamine agonist, in the course of drug-resistant depression. Twenty-three patients with treatment-resistant major depressive episode (MDE) were followed up after a 16-week pramipexole add-on trial. Pramipexole was added to current treatment with TCA or SSRI, at increasing doses from 0.375-1.500 mg/day. The LIFE scale was administered at baseline of the acute trial, at Weeks 16, 32, and 48. Patients were analyzed for sustained remission (score=<2 at LIFE for at least 8 weeks) and recurrence (after remission score > =3 at LIFE for at least 2 weeks) of depression. Of 23 patients, 12 had major depression and 11 had bipolar depression (16 women; mean age=52.8 years). Mean age of onset and median duration of current MDE were 35.1 years and 6 months, respectively; all subjects had at least two prior MDEs. Mean pramipexole dose was 0.990 mg/day. Median duration of follow-up was 28 weeks. Mean baseline MADRS and CGI-S scores were 33.7+/-8.4 (sd) and 4.6+/-0.8, respectively. Median time to sustained remission from baseline was 10 weeks and overall 60.9% (14/23) of subjects recovered within Week 22. Recurrence of depression occurred in 35.7% (5/14) of remitters after Week 24 and within Week 28 from remission. Although there were no sleep attacks, two cases of hypomania and one case of psychotic mania occurred at Weeks 22, 24, and 30, respectively. Pramipexole augmentation of antidepressant treatment was relatively safe and presumably effective in the long-term course of treatment resistant depression.
