Summary

Chronic obstructive pulmonary disease (COPD) is currently the fourth leading cause of death in the United States. Unlike the other leading causes of death, no medical therapies currently available improve the course of disease or affect survival in COPD. Recent investigations suggest that endothelial dysfunction and chronic inflammation is fundamental to COPD. Fish oil intake improves endothelial dysfunction and lowers levels of inflammatory intermediaries which may be important in the development of COPD.

The Chronic Obstructive Pulmonary Disease Fish Oil (COD-Fish) Pilot Trial will enroll 40-45 participants with COPD. These participants will be randomized to receive omega-3 polyunsaturated fatty acid supplementation (PUFA) or placebo (containing corn oil). All participants will perform a number of noninvasive tests (including flow-mediated dilation (FMD) and pulmonary function testing) at study entry as well as every two months for a total of six months. Thirty participants who agree to it will undergo a separate procedure to collect cells from inside a forearm vein for analysis to be compared to 30 controls. The main purpose of this trial is to examine the effect of PUFA on endothelial function as measured by change in FMD in patients with COPD. We hypothesize that in subjects with COPD, treatment with PUFA will increase FMD.

DIETARY_SUPPLEMENT

n-3 polyunsaturated fatty acids

Omax3\[TM\] (Cenestra Health \[TM\]) is a 1 g softgel capsule containing 94.5% omega-3 fatty acids. Each serving size is a 1 gram capsule, which contains 690 mg of eicosapentanoic acid (EPA) and 182 mg of docosahexanoic acid (DHA). Inactive ingredients include: Vitamin E/Tocopherol 2294 ppm (in a carrier of partially hydrogenated vegetable oils including soybean oil), gelatin, glycerol, and purified water (components of the capsule shell). The study participants will be randomized to 3 softgel capsules a day for 6 months.

OTHER

Placebo

3 capsules of matching corn oil placebo
