Background & aims: To assess the effect of an enteral diet enriched with eicosapentaenoic acid (EPA), gamma-linolenic acid (GLA), and anti-oxidants on the incidence of organ dysfunction and nosocomial infections in septic patients with acute lung injury or acute respiratory distress syndrome CARDS) compared with a standard enteral diet.Methods: This prospective, randomized, open-label study was performed in 11 Spanish intensive care units (ICU). Adult patients with sepsis and acute lung injury or ARDS were randomly allocated to receive either an EPA-GLA diet or a control diet.Results: Of the 198 patients that were eligible, 160 were randomized and 132 were studied. Patient demographics, APACHE II and SOFA scores, and nutritional variables on admission were similar between the EPA-GLA diet and control diet groups. The EPA-GLA diet group showed a trend toward a decreased SOFA score, but it was not significant. No differences were observed in the PaO2/FiO(2) ratio or the days on mechanical ventilation between the groups. Incidence of infections was similar in the groups. The control group stayed longer in the ICU than the EPA-GLA diet group (16 vs. 18: p = 0.02).Conclusions: A diet enriched with EPA, GLA, and anti-oxidants does not improve gas exchange or decrease the incidence of novel organ failures in critically ill septic patients with acute lung injury or ARDS. Patients treated with the EPA-GLA diet stayed in the ICU for less time, but we did not find any differences in infectious complications.
