Up to 20% of unvaccinated, hospitalized patients infected with COVID\u201019 may die during the initial three weeks. Our research shows that COVID\u201019 infection results in rapid, remarkable change in the balance between essential fatty acid constituents of plasma phospholipids that are substrates for synthesis of signals that regulate immunity, inflammation, and thrombosis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We assessed if enteral feeding of EPA (eicosapentaenoic acid, 20:5n\u20103) and DHA (docosahexaenoic acid; 22:6n\u20103) normalizes remodeling of plasma phospholipid essential fatty acid content caused by COVID\u201019 viral infection and modifies immune response. Blood samples were taken on day 1 of hospital admission. From the patient record, patients were categorized into two groups based on enteral formula fed by day 5 after admission: enteral feeds that contained EPA\u2009+\u2009DHA or not. These two groups were compared at 1 week and 3 weeks postadmission for plasma phospholipid fatty acids, cytokines, and chemokines.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Feeding EPA\u2009+\u2009DHA increases plasma content of these fatty acids in specific species of plasma phosphatidylcholine. Change in essential fatty acid status was associated with downregulation of the inflammatory signal macrophage inflammatory protein\u20101\u03b2 and increase in interleukin\u201017, monocyte chemoattractant protein (MCP)\u20104, macrophage\u2010derived chemokine and thymus\u2010 and activation\u2010regulated chemokine signals.
