NCT01625845

Brief Summary

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.

Outcome Measures

Primary Outcomes (2)

  • Change in Brachial Flow-Mediated Dilation (FMD) From Pre- to Post- Treatment

    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

    0 and 12 weeks

  • Change in Depressive Symptoms Severity (Hopkins Symptom Checklist Depression Scale; SCL-20) From Pre- to Post- Treatment

    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.

    0 and 12 weeks

Secondary Outcomes (5)

  • Change in Circulating Tumor Necrosis Factor-Alpha (TNF-a) From Pre- to Post-Treatment

    0 and12 weeks

  • Change in Circulating Interleukin-6 (IL-6) From Pre- to Post-Treatment

    0 and 12 weeks

  • Change in Circulating Interleukin-10 (IL-10) From Pre- to Post-Treatment

    0 and 12 weeks

  • Change in Interleukin-1ra (IL-1ra) From Pre- to Post-Treatment

    0 and 12 weeks

  • Change in Circulating C-Reactive Protein (CRP) From Pre- to Post-Treatment

    0 and 12 weeks

Study Arms (2)

Pentoxifylline + Standard Treatment

EXPERIMENTAL

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.

Drug: PentoxifyllineBehavioral: Standard Treatment

Placebo + Standard Treatment

PLACEBO COMPARATOR

Placebos: Placebo pills will match the study drug for color, taste, texture, size, and smell. Participants will receive the same instructions as those randomized to pentoxifylline. 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.

Placebo + Standard Treatment

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. General topics covered include identifying and challenging automatic thoughts, cognitive errors, core beliefs, and attributional styles; activity scheduling; problem solving; graded exposure; task breakdown; sleep management; and relapse prevention. In addition to session work, patients are assigned homeworks that are customized to their needs and reviewed at the start of each session. A progress report, including whether the patient is experiencing suicidal ideation, is generated at the end of each session.

Limitations and Caveats

Missing data precluded analysis of two secondary outcome variables: IL-1α and IL-1β. Due to the very small sample of randomized patients, conclusions should not be drawn from the results of this pilot trial.
