ABSTRACT The objective of this study was to determine the clinical and quality of life outcomes associated with adjunctive treatment of olanzapine added to either lithium or valproic acid/divalproex sodium in patients with bipolar disorder.
Patients with bipolar I disorder, were randomized to receive either olanzapine (5-20 mg) added to mood stabilizer therapy (n=224), or placebo added to mood stabilizer therapy (n=112) for 6 weeks. Changes in clinical outcomes over 6 weeks were measured by the Young Mania Rating Scale (Y-MRS) and the Hamilton Rating Scale for Depression (HAM-D). Quality of life was measured by the Lehman Brief Quality of Life Interview (QLI).
Patients treated with olanzapine added to mood stabilizers, experienced significantly greater mean clinical improvements from baseline on both the Y-MRS and the HAM-D compared to those treated with placebo added to mood stabilizers. Over 6 weeks, patients treated with olanzapine added to mood stabilizers had significantly greater mean improvements from baseline on five of the nine subjective scales on the QLI, compared to patients treated with placebo added to mood stabilizers. Changes in scores on the subjective scales of the QLI were more strongly correlated to changes in depressive symptomatology measured by the HAM-D, than to changes in symptoms of mania measured by the Y-MRS.
The results of this study demonstrate that patients receiving adjunctive treatment have significantly greater improvements in both clinical and quality of life outcomes compared to monotherapy with mood stabilizers.

    • "Also, Dias and colleagues found that depressive symptoms were strong predictors of physical, psychological, and environmental QOL [32]. In addition, it has been shown that eight of the nine QOL dimensions were significantly correlated with HDRS scores by using other instruments to measure QOL [33, 34]. The results of several studies suggest that persistent depressive symptoms are the primary determinant of impaired QOL in BD and these symptoms have been associated with more impairment in job, family, and social life [29, 35–38].

    ABSTRACT: Objectives. The aims of this study were (i) to compare Quality of Life (QOL) of patients with bipolar disorder (BD) type I to those with schizophrenia during a one-year period after hospitalization and (ii) to assess the association of different domains of QOL with severity of clinical symptoms and level of functioning in bipolar patients group. Method. A hundred and two participants were consecutively recruited before discharge from an acute hospitalization. To measure QOL as the main outcome variable, the Farsi (Persian) version of the World Health Organization's QOL Instrument Short Version (WHOQOL BREF) was used. Affective symptoms, overall functioning, and severity of mental illness were assessed as well. The assessment procedure was repeated four, eight, and 12 months after discharge. Results. No significant differences were found between patients with BD and schizophrenia on four domains of WHOQOL BREF at the baseline and the four, eight, and 12 month assessments. Within the subjects with bipolar I disorder, the most stable finding was negative association of depression severity with WHOQOL-BREF on the all four domains during repeated assessments. Conclusion. The findings suggest that persistent depressive symptoms might be the primary determinant of impaired QOL in patients with bipolar I disorder.

    • "A number of psychopharmacological approaches may have promise towards mitigating psychiatric symptoms experienced by this population. Lithium, lamotrigine, quetiapine, olanzapine, risperidone, and aripiprazole have been found to raise mental HRQOL in patients with bipolar disorder (Chand et al., 2004; Endicott et al., 2008; Hirschfeld et al., 2006; Keck et al., 2003; Namjoshi et al., 2004; Zarzar et al., 2007), while use of divalproic acid has not been shown to lead to such improvement (Revicki et al., 2003). None of these studies looked specifically at patients with comorbid PTSD. "

    ABSTRACT: BACKGROUND: Evidence suggests that patients with bipolar disorder have an elevated risk for comorbid posttraumatic stress disorder (PTSD) compared to those without a bipolar diagnosis. Although bipolar disorder is associated with decreased health-related quality of life (HRQOL), it is unclear whether comorbid PTSD interacts to affect HRQOL. METHOD: Baseline data from a multi-site study of patients with bipolar disorder were analyzed. Patient surveys ascertained clinical and demographic information, including physical and mental HRQOL based on the SF-12, mood symptoms (PHQ-9, Internal State Scale), and self-reported co-occurring conditions including PTSD. RESULTS: Overall (N=384), 44.9% of patients self-reported co-occurring PTSD. Patients with PTSD had lower physical and mental HRQOL scores compared to those without PTSD (mean (SD) for those with and without PTSD, respectively): Mental Component Scale score 30.51 (8.22) and 32.86 (8.35); Physical Component Scale score 35.56 (7.77) and 37.21 (7.20). After adjusting for demographic and clinical factors including mood symptoms, multiple linear regression analyses revealed that PTSD was no longer significantly associated with physical or mental HRQOL; however, depressive symptoms were independently associated with mental HRQOL (Beta -0.63, p<0.01). CONCLUSION: Depressive symptoms may explain the association between PTSD and mental HRQOL. Clinicians working with these patients will want to emphasize treatment of depression as important towards improving HRQOL for this group.

    • "Improvements in the Olanzapine cohort were significantly greater than the improvements recorded in the Other cohort on both measures. The improvement was consistent with changes recorded in the Hamilton Depression Rating Scale at six weeks in patients taking combined olanzapine and a mood stabilizer[4,20]. On the other hand, a review of six olanzapine trials[9] found olanzapine to be no more efficacious than divalproex in reducing depressive symptoms. "

    ABSTRACT: Bipolar illness is associated with significant psychosocial morbidity and health resource utilization. Second generation antipsychotics, used alone or in combination with mood stabilizers are effective in treating acute mania in community settings. This study was designed to compare the change in clinical parameters and resource utilization at one month in a group of patients who required treatment intervention for exacerbation of mania. The clinical response at one year was also evaluated. 496 patients were enrolled at 75 psychiatric practices across Canada. The Olanzapine cohort (n = 287) included patients who had olanzapine added to their medication regimen or the dose of olanzapine increased. The Other cohort (n = 209) had a medication other than olanzapine added or the dose adjusted. Changes from baseline in the Young Mania Rating Scale (YMRS), Montgomery Asberg Depression Rating Scale, Beck Anxiety Inventory and SF-12 Health Survey were compared at one month using ANCOVA. Categorical variables at one month for health resource utilization, employment status, abuse/dependency, and the number of suicide attempts were compared using Fisher's Exact test. Patients were followed for one year and a subgroup was evaluated. At one month, patients in the Olanzapine cohort recorded a mean reduction in the YMRS of 11.5, significantly greater than the mean reduction in the Other cohort of 9.7 (ANCOVA P = 0.002). The Olanzapine cohort was significantly improved compared to the Other cohort on the scales for depression and anxiety and did not experience the deterioration in physical functioning seen in the Other cohort. No significant differences were detected in health-related quality-of-life measures, employment status, drug abuse/dependency, number of suicide attempts, mental functioning, emergency room visits or inpatient psychiatric hospitalizations. In a subgroup treated for 12 months with a single second generation antipsychotic, improvements in illness severity measures were maintained with no evidence of significant differences among the antipsychotics. Patients with bipolar disorder requiring treatment intervention for exacerbation of mania in the community setting responded to olanzapine at one month. In a subset analysis, second generation antipsychotic treatment continued to be beneficial in reducing bipolar symptoms at one year.
