The safety and tolerability of duloxetine in depressed elderly patients with and without medical comorbidity

INTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 8 2007
T. N. Wise
Summary Aim and methods:, The impact of medical comorbidity on the efficacy and tolerability of duloxetine in elderly patients with major depressive disorder (MDD) was investigated in this study. Data were obtained from a multicentre, randomised, double-blind, placebo-controlled study in 311 patients with MDD aged 65,89. The primary outcome measure was a prespecified composite cognitive score based on four cognitive tests: (i) Verbal Learning and Recall Test; (ii) Symbol Digit Substitution Test; (iii) 2-Digit Cancellation Test and (iv) Letter-Number Sequencing Test. Secondary measures included the Geriatric Depression Scale (GDS), 17-Item Hamilton Depression Scale (HAMD17), Clinical Global Impression-Severity (CGI-S) Scale, Visual Analogue Scale (VAS) for pain and 36-Item Short Form Health Survey (SF-36). Tolerability measures included adverse events reported as the reason for discontinuation and treatment-emergent adverse events (TEAEs). The consistency of the effect of duloxetine vs. placebo comparing patients with and without medical comorbidity (vascular disease, diabetes, arthritis or any of these) was investigated. Results:, Overall, duloxetine 60 mg/day demonstrated significantly greater improvement compared with placebo for the composite cognitive score, GDS and HAMD17 total scores, CGI-Severity, HAMD17 response and remission rates, and some of the SF-36 and VAS measures. There were few significant treatment-by-comorbidity subgroup interactions for these efficacy variables, or for adverse events reported as the reason for discontinuation and common TEAEs. Conclusions:, The present analyses suggested that the efficacy of duloxetine on cognition and depression in elderly patients, and its tolerability, were not largely affected by the comorbidity status. These results further support the use of duloxetine in elderly patients with MDD. [source]


Problem solving therapy for the depression-executive dysfunction syndrome of late life

INTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 8 2008
George S. Alexopoulos
Abstract Background The ,depression executive dysfunction syndrome' afflicts a considerable number of depressed elderly patients and may be resistant to conventional pharmacotherapy. Non-pharmacological approaches addressing their behavioral deficits may reduce disability and experienced stress and improve depression. Methods This paper focuses on problem solving therapy (PST) because it targets concrete problems that can be understood by patients with executive dysfunction and trains patients to address them using an easy to comprehend structured approach. Results We suggest that PST is a suitable treatment for patients with the depression-executive dysfunction syndrome because it has been found effective in uncomplicated geriatric major depression and in other psychiatric disorders accompanied by severe executive dysfunction. Furthermore, PST can address specific clinical features of depressed patients with executive dysfunction, especially when modified to address difficulties with affect regulation, initiation and perseveration. Conclusions A preliminary study suggests that appropriately modified PST improves problem solving skills, depression and disability in elderly patients with the depression-executive dysfunction syndrome of late life. If these findings are confirmed, PST may become a therapeutic option for a large group of depressed elderly patients likely to be drug resistant. Copyright © 2008 John Wiley & Sons, Ltd. [source]


Anterior cingulate dysfunction in geriatric depression

INTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 4 2008
George S. Alexopoulos
Abstract Background Although several brain abnormalities have been identified in geriatric depression, their relationship to the pathophysiological mechanisms leading to the development and perpetuation of this syndrome remain unclear. Methods This paper reviews findings on the anterior cingulate cortex (ACC) function and on the relationship of ACC abnormalities to the clinical presentation and the course of geriatric depression in order to elucidate the pathophysiological role of ACC in this disorder. Results The ACC is responsible for conflict detection and emotional evaluation of error and is connected to brain structures that regulate mood, emotional valence of thought and autonomic and visceral responses, which are functions disturbed in depression. Geriatric depression often is accompanied by abnormalities in some executive functions and has a clinical presentation consistent with ACC abnormalities. Indices of ACC dysfunction are associated with adverse outcomes of geriatric depression. Conclusions Converging findings suggest that at least some ACC functions are abnormal in depression and these abnormalities are pathophysiologically meaningful. Indices of ACC dysfunction may be used to identify subgroups of depressed elderly patients with distinct illness course and treatment needs and serve as the theoretical background for novel treatment development.

Hippocampal volume and antidepressant response in geriatric depression

INTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 6 2002

Abstract Background Biological markers of treatment response may include structural brain changes seen on neuroimaging. While most imaging studies have focused on cerebrovascular disease, evidence is growing that the hippocampus may play a role in depression, particularly geriatric depression. Method We studied 60 depressed elderly patients enrolled in a longitudinal study who were treated with antidepressant medications using a treatment guideline-based approach. Baseline and 12-week Montgomery-Asberg Depression Rating Scale (MADRS) scores were obtained via interview with a geriatric psychiatrist. All subjects had a baseline magnetic resonance imaging (MRI) brain scan. MRI scans were processed using standard protocols to determine total cerebral volume and right and left hippocampal volumes. Hippocampal volumes were standardized for total cerebral volume. MADRS scores less than 10 were used to define remission. Results When the group with the lowest quartile of standardized hippocampal volumes was compared to those above the first quartile, those with small right and total hippocampal volumes were less likely to achieve remission. In a subsequent logistic regression model controlling for age small standardized right hippocampal volumes remained significantly associated with remission. Conclusion Further studies with larger sample are needed to determine if left-right hippocampal volume differences do exist in depression, and basic neuroscience studies will need to elucidate the role of the hippocampus in geriatric depression.

The systematic assessment of depressed elderly primary care patients

INTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 6 2001
Patrick J. Raue
Abstract Studies of the primary care treatment of depressed elderly patients are constrained by limited time and space and by subject burden. Research assessments must balance these constraints with the need for obtaining clinically meaningful information. Due to the wide-ranging impact of depression, assessments should also focus on suicidality, hopelessness, substance abuse, anxiety, cognitive functioning, medical comorbidity, functional disability, social support, personality, service use and satisfaction with services. This paper describes considerations concerning the assessment selection process for primary care studies, using the PROSPECT (Prevention of Suicide in Primary Care Elderly: Collaborative Trial) study as an example. Strategies are discussed for ensuring that data are complete, valid and reliable. Copyright © 2001 John Wiley & Sons, Ltd. [source]


Estimation and Inference for the Causal Effect of Receiving Treatment on a Multinomial Outcome

BIOMETRICS, Issue 1 2009
Jing Cheng
Summary This article considers the analysis of two-arm randomized trials with noncompliance, which have a multinomial outcome. We first define the causal effect in these trials as some function of outcome distributions of compliers with and without treatment (e.g., the complier average causal effect, the measure of stochastic superiority of treatment over control for compliers), then estimate the causal effect with the likelihood method. Next, based on the likelihood-ratio (LR) statistic, we test those functions of or the equality of the outcome distributions of compliers with and without treatment. Although the corresponding LR statistic follows a chi-squared (,2) distribution asymptotically when the true values of parameters are in the interior of the parameter space under the null, its asymptotic distribution is not ,2 when the true values of parameters are on the boundary of the parameter space under the null. Therefore, we propose a bootstrap/double bootstrap version of a LR test for the causal effect in these trials. The methods are illustrated by an analysis of data from a randomized trial of an encouragement intervention to improve adherence to prescribed depression treatments among depressed elderly patients in primary care practices.
