Evaluation and treatment of major depression (MDD) in elderly patients is frequently complicated by the presence of comorbid medical conditions, which can reduce the effect of depression treatment, leading to lower rates of depressive-symptom improvement and higher rates of relapse.
Objective
The authors investigated results of antidepressant concurrent with arthritis pain treatment in elderly patients.
Method
Patients age 65 and over with recurrent MDD were stratified by arthritis status and randomized to duloxetine (a dual reuptake-inhibitor of serotonin and norepinephrine) or placebo treatment for 8 weeks (duloxetine, N = 117; placebo, N = 55).
Results
Duloxetine significantly reduced MDD symptom severity in elderly patients with and without arthritis, and produced significant reduction in several pain measures in those patients with comorbid arthritis.
Discussion
The magnitude and time-course of depressive symptom improvement did not differ significantly between patients with and without arthritis. Some studies have suggested that the severity of pain in arthritis patients may be linked to depression severity.
