Efficacy and safety of antidepressant monotherapy in the treatment of bipolar-II depression.
ABSTRACT Sparse data exist regarding the risks and benefits of treating bipolar-II depression with antidepressants alone. On the basis of studies of bipolar-I patients, treatment guidelines suggest antidepressants should be augmented with mood stabilizers. Whether these recommendations apply to bipolar-II is unclear. A post-hoc analysis of a double-blind study, which compared the relative efficacy of placebo, imipramine and phenelzine in depressed outpatients. Patients rated 1 ('very much improved') or 2 ('much improved') on the Clinical Global Inventory Scale were considered responders. In an intent to treat analysis, no significant differences between bipolar patients (N=62) and unipolar patients (N=248) in response rates to placebo, imipramine and phenelzine were seen. No patient developed manic symptoms that required medication discontinuation or mood stabilizer augmentation. Antidepressant monotherapy was found to be a safe and effective treatment for bipolar-II depression.

ABSTRACT: Many new approaches have been adopted for the treatment of bipolar disorder (BD) in the past few years, which strived to produce more positive outcomes. To enhance the quality of care, several guideline recommendations have been developed. For study purposes, we monitored the prescription of psychotropic drugs administered to bipolar patients who had been referred to tertiary care services, and assessed the degree to which treatment met specific guidelines. Between December 2006 and February 2009, we assessed 113 individuals suffering from BD who had been referred to the Royal Ottawa Mental Health Centre (ROMHC) Mood Disorders Program by physicians within the community, mostly general practitioners. The Structured Clinical Interview for DSM-IV-TR was used to assess diagnosis. The prescribed treatment was compared with specific Canadian guidelines (CANMAT, 2009). Univariate analyses and logistic regression were used to assess the contribution of demographic and clinical factors for concordance of treatment with guidelines. Thirty-two subjects had BD type I (BD-I), and 81 subjects had BD type II (BD-II). All subjects with BD-I, and 90% of the BD-II group were given at least one psychotropic treatment. Lithium was more often prescribed for subjects with BD-I (62%) than those with BD-II (19%). Antidepressants were the most frequently prescribed class of psychotropics. Sixty-eight percent of subjects received treatment concordant with guidelines by medication and dose. The presence of a current hypomanic episode was independently associated with poorer concordance to guidelines. In more than half the cases, the inappropriate use of antidepressants was at the origin of the non concordance of treatment with respect to guidelines. Absence of psychotropic treatment in bipolar II patients and inadequate dosage of mood stabilizers were the two other main causes of non concordance with guidelines. The factors related to treatment not concordant with guidelines should be further explored to determine appropriate strategies in implementing the use of guidelines in clinical practice.BMC Psychiatry 08/2013; 13(1):211.
