title: Is antioxidant and n-3 supplementation able to improve functional status in poststroke patients? Results from the Nutristroke Trial.
abstract: BACKGROUND
  To test whether supplementary antioxidants and n-3 fatty acids, alone or in combination, could improve functional status in stroke survivors.
  
  
  METHODS
  We performed a randomized, double-blind, placebo-controlled clinical trial in 72 stroke patients (47 males; age 65.3 +/- 12.9 years) admitted to a rehabilitation hospital for sequelae of first-ever ischemic stroke, and divided them into 4 subgroups. Group 1 patients received daily oral antioxidants, group 2 received n-3 polyunsaturated fatty acids, group 3 both supplements, and group 4 placebo, all for 12 months. No difference at baseline was observed among groups in neurological severity or in disability. All measures were repeated after 6 and 12 months of treatment. All major clinical events were recorded.
  
  
  RESULTS
  At baseline, 25% of the patients had a low plasma vitamin status, and 48.5% was at risk of undernutrition. At the 1-year follow-up, we observed a trend for lower mortality (p = 0.060) in subgroups treated with n-3 fatty acids, but without significant differences in rehabilitation result status among groups.
  
  
  CONCLUSIONS
  Malnutrition is widely observed in patients admitted to a rehabilitative hospital for stroke rehabilitation, and dietary supplementation, even if not able to improve rehabilitation results, is likely to reduce mortality at the 1-year follow-up.
