Treatment With a Marine Oil Supplement Alters Lipid Mediators and Leukocyte Phenotype in Healthy Patients and Those With Peripheral Artery Disease

What Is New? This is the first study to elucidate the omega‐3 and omega‐6 polyunsaturated fatty acid lipid mediator profile in peripheral artery disease. We have shown that a short‐course, oral marine oil supplement can remodel these lipid mediator pathways to induce a less inflammatory and pro‐resolution phenotype. What Are the Clinical Implications? This study provides a foundation for characterizing biochemical and cellular biomarkers of inflammation and resolution in peripheral artery disease to allow for future work correlating upstream nutritional or pharmacologic interventions, immune cell function, and downstream clinical events.
