OBJECTIVES: Enteral diets enriched with eicosapentaenoic acid (EPA), gamma-linolenic acid (GLA), and antioxidants have previously been shown to improve outcomes in patients with acute respiratory distress syndrome. Several studies using animal models of sepsis demonstrate that enteral nutrition enriched with omega-3 fatty acids reduces mortality rate. This study investigated whether an enteral diet enriched with EPA, GLA, and antioxidant vitamins can improve outcomes and reduce 28-day all-cause mortality in patients with severe sepsis or septic shock requiring mechanical ventilation. DESIGN: Prospective, double-blind, placebo-controlled, randomized trial. SETTING:Three different intensive care units of a tertiary hospital in Brazil. PATIENTS: The study enrolled 165 patients. INTERVENTIONS: Patients were randomized to be continuously tube-fed with either a diet enriched with EPA, GLA, and elevated antioxidants or an isonitrogenous and isocaloric control diet, delivered at a constant rate to achieve a minimum of 75% of basal energy expenditure x 1.3 during a minimum of 4 days. MEASUREMENTS AND MAIN RESULTS: Patients were monitored for 28 days. Patients who were fed with the study diet experienced a significant reduction in mortality rate compared with patients fed with the control diet, the absolute mortality reduction amounting to 19.4% (p = .037). The group who received the study diet also experienced significant improvements in oxygenation status, more ventilator-free days (13.4 +/- 1.2 vs. 5.8 +/- 1.0, p < .001), more intensive care unit (ICU)-free days (10.8 +/- 1.1 vs. 4.6 +/- 0.9, p < .001), and a lesser development of new organ dysfunctions (p < .001). CONCLUSIONS: In patients with severe sepsis or septic shock and requiring mechanical ventilation and tolerating enteral nutrition, a diet enriched with EPA, GLA, and elevated antioxidants contributed to better ICU and hospital outcomes and was associated with lower mortality rates.
