Abstract
BACKGROUND To identify demographic and clinical characteristics of bipolar depressed patients who require antidepressant (AD) augmentation, and to evaluate the short- and long-term effectiveness and safety of this therapeutic strategy. METHODS One hundred twenty-two bipolar depressed patients were consecutively recruited, 71.7% of them received mood stabilizers (MS)/second-generation antipsychotics (SGA) with AD-augmentation and 28.3% did not. Patients were evaluated at baseline, and after 12 weeks and 15 months of treatment. RESULTS The AD-augmentation was significantly higher in patients with bipolar II compared with bipolar I diagnosis. Patients with MS/SGA + AD had often a seasonal pattern, depressive polarity onset, depressive index episode with anxious features, a low number of previous psychotic and (hypo)manic episodes and of switch. They had a low irritable premorbid temperament, a low risk of suicide attempts, and a low number of manic symptoms at baseline. After 12 weeks of treatment, 82% of patients receiving ADs improved, 58% responded and 51% remitted, 3.8% had suicidal thoughts or projects, 6.1% had (hypo)manic switch, and 4.1% needed hospitalization. During the following 12 months, 92% of them remitted from index episode, 25.5% did not relapse, and 11% needed hospitalization. Although at the start advantaged, patients with AD-augmentation, compared with those without AD-augmentation, did not significantly differ on any outcome as well on adverse events in the short- and long-term treatment. CONCLUSION Our findings indicate that ADs, combined with MS and/or SGA, are short and long term effective and safe in a specific subgroup for bipolar depressed patients.

Response and remission rates during 24 weeks of mood-stabilizing treatment for bipolar depression depending on early non-response. Psychiatry Res 2021; 305:114194. [PMID: 34500184 DOI: 10.1016/j.psychres.2021.114194] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/27/2021] [Revised: 08/15/2021] [Accepted: 08/27/2021] [Indexed: 11/26/2022]
Abstract
BACKGROUND We aimed to study the probability of bipolar depression response at 24 weeks given initial non-response. METHODS We combined two multi-site, 24-week trials including similar populations following the same evidence-based guidelines randomizing patients to lithium or quetiapine. Additional mood-stabilizing treatment was possible if clinically indicated. We report cumulative proportions of response (>50% improvement in MADRS) and remission (MADRS<10). RESULTS We included 592 participants with bipolar depression (mean 39 years, 59% female, mean MADRS 25). Among 393 (66%) participants without response after 2 weeks, 46% responded by 24 weeks; for 291 (49%) without response at 4 weeks, 40% responded and 33% remitted by 24 weeks; for 222 (38%) without a response at 6 weeks, 36% responded and 29% remitted by 24 weeks; for 185 (31%) without a response at 8 weeks, 29% responded and 24% remitted by 24 weeks. Rates were similar for participants who had started an additional mood-stabilizing drug during the first 6 or 8 weeks. CONCLUSIONS Among patients with bipolar depression and non-response after 6 weeks treatment, representing an adequate bipolar depression trial, only one-third responded by 24 weeks. These results highlight the need for better treatment alternatives for non-responders to evidence-based treatments for bipolar depression.
