Brief summary

The goal of this open-administration treatment study of citalopram (or duloxetine) is to evaluate the effect of antidepressant medication on treating the syndrome of frailty in older adults with depressive symptoms. Patients with significant depressive symptoms (defined as CES-D (Center for Epidemiological Studies - Depression scale) \> 10) and 1 or more symptoms of the frailty syndrome (exhaustion, decreased energy, weight loss, decreased grip strength, and slow/unsteady gait) will be evaluated and treated with citalopram (or duloxetine) for 8 weeks to test whether antidepressant medication improves both the syndrome of frailty and depressive symptoms. Patients evaluated at the Adult and Late Life Depression clinic and eligible to participate in the study will be treated with an antidepressant medication and assessed on the primary outcome variables (characteristics of frailty, depressive symptoms) as well as on secondary variables which include cognition (global cognition, episodic memory, executive function), and function (physical mobility, instrumental activities of daily living, and social functioning) prior to treatment initiation and following 8-weeks of treatment. The hypotheses for this protocol predict that we will discover a significant improvement on both frailty characteristics and depressive symptoms in this clinical population when treated with antidepressant medication (citalopram or duloxetine).

Detailed description

Frailty, a syndrome of decreased resiliency and reserves, is defined by five characteristics: 1)shrinking (definition: unintentional weight loss of \> 10 lbs in prior year, or \> 5% loss of body weight in prior year at follow-up), 2) weakness (definition: grip strength in lowest 20% at baseline, adjusted for gender and BMI), 3) poor endurance/energy (definition: self-report of exhaustion on 2 items on the CES-D), 4) slowness (definition: slowest 20% on timed 4 meter or 15 foot walk, adjusted for gender and standing height), and 5) low physical activity (definition: weighted score of kilocalories expended per week as calculated from the Minnesota Leisure Time Activity questionnaire). Frailty is associated with poor prognosis including hospitalization, falls, worsening disability and mobility, and death. Data from the Cardiovascular Health Study document the rate of comorbid depressive symptoms in frail older adults (16.2% of older adults with at least 1 frailty characteristic had a CES-D \> 10, including 31% of older adults with 3 or more frailty characteristics, compared to 2.6% of nonfrail older adults) despite study exclusion of individuals who were taking an antidepressant (this is in part why we chose to include patients with a CES-D of \> 10, rather than requiring a diagnosis of a depressive disorder such as major depression or dysthymia for this study). The relationship between frailty and depression however goes beyond this association; the five defining characteristics of frailty (exhaustion, decreased energy, weight loss, decreased grip strength, and slow/unsteady gait) overlap significantly with symptoms of geriatric depression (decreased energy and motivation, psychomotor slowing, weight loss, decreased participation in leisure activities). The proposed study is innovative in that it is focuses on a group of older adults who have been unrepresented (via exclusion criteria) in previous clinical studies (frail older adults with comorbid depressive symptoms), and it treats the comorbid depressive symptoms and targets characteristics of the frailty syndrome in the hopes of altering the prognostic trajectory of this clinical sample. This protocol serves two purposes: 1. It tests the feasibility of recruiting and retaining frail older adults with depressive symptoms in a treatment trial, and 2. It provides pilot data for the effectiveness of an antidepressant medication on treating the characteristics of frailty and the comorbid depressive symptoms.

Interventions

If patient has a history of non-response or cannot tolerate escitalopram and/or duloxetine, then they will be treated openly with an approved antidepressant.

The scores assigned to each of the items: none (0), mild (1) moderate (2), severe (3), and extreme (4) - are summed. Each of the items is simply added up without recoding or collapsing of response categories; thus, there is no weighting of individual items. As a result, the simple sum of the scores of the items across all domains constitutes a statistic that is sufficient to describe the degree of functional limitations. Step 1 - Summing of recoded item scores within each domain. Step 2 - Summing of all six domain scores. Step 3 - Converting the summary score into a metric ranging from 0 to 100 (where 0 = no disability; 100 = full disability).

Time frame: 12 Months

Population: Of the 71 who continued with treatment past 8-weeks, 11 dropped out between the 6- and 12-month assessment points. As such, 60 patients underwent 12-month assessments and were analyzable at 12-months.

Time frame: Month 6

Population: Of the initial 100 patients assessed at baseline, 29 participants chose to not continue treatment past 8-weeks. As such, only 71 continued into the 10-month continuation phase of the project. Although these 29 were slightly older than the 71 who continued, they did not differ from those who continued in any other way including depression severity at baseline or 8-week treatment response. Because these 29 opted out of treatment after 8-weeks, only 71 were able to be analyzed at 6-months.

World Health Organization Disability Assessment 2.0 (36-item)

Assesses the level of functioning of patients, a component of the frailty evaluation. Simple: the scores assigned to each of the items - none (0), mild (1) moderate (2), severe (3), and extreme (4) - are summed. This method is referred to as simple scoring because the scores from each of the items are simply added up without recoding or collapsing of response categories; thus, there is no weighting of individual items. This approach is practical to use as a hand-scoring approach and may be the method of choice in busy clinical settings or in paper-pencil interview situations. As a result, the simple sum of the scores of the items across all domains constitutes a statistic that is sufficient to describe the degree of functional limitations. Step 1 - Summing of recoded item scores within each domain. Step 2 - Summing of all six domain scores.
