Therapy for depression in bipolar affective disorder
Abstract
Objective: to evaluate the efficiency and safety of different therapy regimens for depression in relation to the clinical type of bipolar affective disorders (BAD) and to choose optimal treatment regimens for depression in BAD type I (BADI) and BAD type II (BADII).Patients and methods. A total of 65 depressive patients, including 25 with BADI and 37 with BADII, were examined. 212 depressive episodes were analyzed in BAD patients, of them there were 74 with BADI and 138 with BADII. The patients with BADI took a combination of an antidepressant (AD) and a normothymic (NT), NT and a neuroleptic (NL), AD, NT and NL. Those with BADII received monotherapy with AD or NL, a combination of AD + NT, AD + NL. The patients' status was clinically evaluated using a specially designed questionnaire and the MADRS and CGI psychometric scales at baseline and then at the end of 1, 2, 4, and 8 weeks of therapy.Results. The AD-containing regimens used to treat patients with BADI proved to be more effective; this therapy led to a more marked reduction in depressive symptoms (55.73% in the AD + NT-treated patients; 54.07% in the AD + NT + NL group versus 33.64% in the NT + NL-treated patients), a higher response to therapy, and a larger number of remissions by the end of the investigation (80.0, 72.7, and 33.3%, respectively). Moreover, the incidence of transient hypomanic symptoms did not significantly differ in these groups (20.0, 27.3, and 8.3%, respectively). The depressive patients with BADII generally responded better to different therapy regimens (the reduction in depressive symptoms was 52.08, 58.82, 58.40, and 53.98% in the AD, NL, AD + NT, and AD + NL groups; the remission index by the end of the investigation was 60.6, 92.9, 77.8, and 69.2%, respectively); these patients were seen to have less frequently symptoms of an antipole during their treatment (18.2, 7.1, 0.0, and 15.4%, respectively).Conclusion. The incorporation of AD into a therapy regimen in BAD patients accelerates emergence from any depression severity and considerably enhances the efficiency of treatment. According to the clinical picture of depression, both AD monotherapy (BADII) and a combination of AD + NT and/or NL (BADI, BADII) may be used. The incorporation of AD into a therapy regimen does not significantly increase a risk for developing an inverse phase.
