A randomized trial of glutamine and antioxidants in critically ill patients.
Study answer
What this study found
Early supplementation did not improve outcomes overall, and glutamine was associated with worse survival. For 28-day mortality, glutamine increased death versus no glutamine (32.4% vs 27.2%; adjusted odds ratio 1.28, 95% CI 1.00 to 1.64; P = 0.05), while antioxidants had no significant effect (30.8% vs 28.8%; adjusted odds ratio 1.09, 95% CI 0.86 to 1.40; P = 0.48). In-hospital mortality and 6-month mortality were also significantly higher among patients who received glutamine. Serious adverse events occurred in 52 cases among 46 patients, with 4 considered potentially related to study…
- Study & population
- Randomized, multicenter, factorial trial in critically ill adults with multiorgan failure requiring mechanical ventilation.
- Intervention
- This 2x2 factorial trial tested early nutritional supplementation with glutamine, antioxidants, or both, compared with matched placebo.
- Key limitation
- Complex factorial design with multiple active regimens makes isolated attribution less straightforward, and the excerpt provides limited arm-specific detail for secondary outcomes.

BACKGROUND Critically ill patients have considerable oxidative stress. Glutamine and antioxidant supplementation may offer therapeutic benefit, although current data are conflicting. METHODS In this blinded 2-by-2 factorial trial, we randomly assigne…
