RESUMO
Cognitive symptoms in major depressive disorder (MDD) contribute to impaired functional abilities and work productivity, particularly presenteeism. We investigated the association between baseline cognitive symptoms and subsequent presenteeism, and global functional impairment in Japanese patients with MDD from PERFORM-J (Prospective Epidemiological Research on Functioning Outcomes Related to Major Depressive Disorder in Japan) - a 6-month, multicenter, epidemiological study data. A total of 518 patients initiating antidepressant monotherapy (first-line or switched from another drug) were enrolled. Assessments include Perceived Deficits Questionnaire - Depression (PDQ-D) for cognitive complaints, Sheehan Disability Scale (SDS) for global function (analysed n = 318), and Work Productivity and Activity Impairment Questionnaire for presenteeism (analysed n = 122). A strong association between changes in presenteeism and changes in SDS scores (r: total = 0.636; work/school = 0.686) was observed. After adjusting for sociodemographic and MDD-related factors, patients without cognitive complaints at baseline showed lower odds of impaired presenteeism at 6 months versus patients with cognitive complaints (0.243, 95% CI: 0.079 to 0.747, p = 0.014) and also in patients with first episode of MDD against with recurrent MDD (0.327 (95% CI: 0.136 to 0.787). Similarly, patients without cognitive complaints had healthier global functioning (lower mean SDS total score) than patients with cognitive complaints (8.3 vs 11.2; 95% CI, -5.189 to -0.578; p = 0.014). First depressive episode (lower risk of presenteeism), being male, and low baseline SDS total score (better global functioning) were also associated with improved outcomes. These results highlight the potential value of baseline PDQ-D scores in predicting subsequent workplace and global functioning in patients undergoing treatment for MDD.

BACKGROUND: Patients with major depressive disorder (MDD) frequently retain cognitive disturbances after recovery from mood symptoms. We investigated the relationship between early response of mood symptoms and/or remission, and residual cognitive disturbances after 6 months of antidepressant treatment. METHODS: 518 patients with MDD were followed up for 6 months after antidepressant treatment initiation (first-line or switch from a previous drug). Subjective and objective cognitive disturbances were assessed by the Perceived Deficits Questionnaire - Depression (PDQ-D) and digit symbol substitution test (DSST), respectively. Depressive symptoms, as well as remission and early response to treatment, were assessed using the Montgomery-Asberg Depression Rating Scale (MADRS). Multivariable linear and logistic regression models were used to adjust for confounders. RESULTS: Early response of depressive mood (≥50% reduction in MADRS score at month 1) was related with fewer residual subjective cognitive symptoms, as evaluated by the PDQ-D at month 6 (p<0.001). Likewise, early remission status at month 2 was inversely associated with PDQ-D scores at month 6 (p<0.001). Among patients with baseline DSST scores of ≥1 standard deviation below the norm, early response/remission was associated with better performance on the DSST at month 6 (p<0.05). LIMITATIONS: The cohort may not be representative of the general MDD patient population, and the possible influence of concomitant medications was not evaluated. CONCLUSIONS: These findings suggest that early improvements in depressive symptoms predict better cognitive outcomes in patients with MDD. Grouping of patients by mood and cognition status in early stages of antidepressant treatments may facilitate efforts to improve long-term functional outcomes.

BACKGROUND: Anxiety symptoms are common in patients with major depressive disorder (MDD) and usually confer worse treatment outcomes. The long-term, open-label AtWoRC study in working patients with MDD treated with vortioxetine demonstrated a significant correlation between severity of anxiety symptoms and impaired work productivity. This analysis was undertaken to further explore clinical characteristics and treatment outcomes in patients with different levels of severity of anxiety symptoms at baseline. METHODS: Post hoc analysis in 199 working patients with MDD treated with vortioxetine (10-20 mg/day), stratified by Generalized Anxiety Disorder 7-item (GAD-7) score at baseline [mild/moderate anxiety (GAD-7 ⩽14), n = 83; severe anxiety (GAD-7 ⩾15), n = 116]. Associations were examined between GAD-7 and other outcome assessment scores at baseline. Observed mean changes from baseline to week 52 were compared between groups. RESULTS: Patients with severe anxiety had significantly worse depressive and cognitive symptoms, functioning, and work productivity at baseline than those with mild/moderate anxiety, but similar cognitive performance. Statistically significant improvements from baseline were seen for all outcomes after 52 weeks of vortioxetine treatment, with no significant differences observed between the two groups after adjustment for baseline anxiety scores. CONCLUSION: Treatment with vortioxetine was associated with long-term improvement in clinical symptoms and measures of work productivity in patients with MDD in a real-world setting, irrespective of severity of anxiety symptoms at the start of treatment.
