简要总结
The objective of this clinical trial is to evaluate whether an anti-inflammatory medication, pentoxifylline, reduces depressive symptoms and improves artery function. Participants in this trial will be older primary care patients (60 years and up) who are depressed but do not have a history of cardiovascular disease. Half of these patients will receive pentoxifylline, and half will receive placebo. In addition, participants in both arms will receive an evidence-based psychological treatment called Beating the Blues®, which is a computerized, cognitive behavioral treatment program for depression. The investigators will use questionnaires to assess change in depressive symptoms and an ultrasound test to measure change in artery function from pre- to post-treatment. It is hypothesized that patients who receive pentoxifylline will show greater improvements in both depression and artery function than patients who receive placebo.
详细描述
Cardiovascular disease is the leading cause of death, and depression is the leading cause of disability in the United States. Previous research suggests that systemic inflammation may play an important role in the development of both depression and cardiovascular disease. Therefore, Aim #1 of this study is to examine whether adding an anti-inflammatory medication (pentoxifylline) to standard depression treatment (cognitive-behavioral therapy) improves both depressive symptoms and endothelial dysfunction, a sign of early cardiovascular disease. Aim #2 is to evaluate candidate mediators of treatment effects by examining whether reductions in multiple markers of systemic inflammation account for treatment-related improvements in depressive symptoms and endothelial dysfunction. To achieve these aims, a clinical trial of older depressed primary care patients free of cardiovascular disease is being conducted. Patients will be randomized to one of two groups: a standard depression treatment (a cognitive-behavioral treatment program) plus pentoxifylline or standard depression treatment plus placebo. The treatment phase of the study will be 12 weeks. At baseline, 6 weeks, and 12 weeks, patients will undergo assessments of depressive symptoms, various inflammatory markers, and endothelial function. Our index of endothelial function is brachial artery flow-mediated dilation, a noninvasive measure of endothelial function. Demonstrating that medications targeting systemic inflammation are effective for concurrently treating late-life depression and reducing CAD risk would place anti-inflammatory approaches in the collection of depression treatment strategies, as well as CAD prevention strategies, of the primary care provider. This change to clinical practice should result in improved management of both late-life depression and cardiovascular risk, which in turn would reduce disability, CAD morbidity, and mortality among older adults.

研究组 & 干预措施
Pentoxifylline + Standard Treatment
Pentoxifylline: Pentoxifylline is phosphodiesterase inhibitor that interferes with proinflammatory cytokine signaling and synthesis. Participants will be instructed to take pentoxifylline 400 mg p.o. t.i.d. for 12 weeks.
Standard Treatment: Beating the Blues (BtB) is a widely used, empirically supported, computer-based, CBT program for depression designed for use in primary care clinics. BtB utilizes an interactive, multimedia format to deliver and eight 50-minute, weekly therapy sessions.

结局指标
主要结局
Change in Brachial Flow-Mediated Dilation (FMD) From Pre- to Post- Treatment
时间窗: 0 and 12 weeks
Patients underwent ultrasound assessment of brachial FMD in accordance with established guidelines at pre- (0 weeks) and post- (12 weeks) treatment. After a 10-minute supine rest, high-resolution baseline images of the brachial artery were obtained from 3 consecutive cardiac cycles. Next, the forearm cuff was inflated to 250 mmHg for 5 minutes and then was rapidly deflated. At 60 and 90 seconds post-deflation, images from 3 consecutive cardiac cycles were acquired. FMD values were computed as the % change in brachial diameter at either 60 or 90 seconds after cuff deflation
Change in Depressive Symptoms Severity (Hopkins Symptom Checklist Depression Scale; SCL-20) From Pre- to Post- Treatment
时间窗: 0 and 12 weeks
Self-reported depressive symptom severity was measured at pre- (0 weeks) and post- (12 weeks) treatment visits by the 20 depression items from the Symptom Checklist 90 (Hopkins Symptom Checklist depression scale; SCL-20). Each item on the scale ranges from 0 (not at all) to 4 (extremely). Total scores are the average across all response items and range from 0 to 4 with higher scores indicating greater levels of depressive symptoms.
