FARRIOL, M. et al. Ingestion of antioxidants and polyamines in patients with severe burns. Nutr. Hosp. [online]. 2004, vol.19, n.5, pp.300-304. ISSN 1699-5198.

Starting the first 24 hours after burn injury, energy supply, antioxidants and polyamines were assessed in 25 severe burn patients (20 men and 5 women) with a mean age of 45.6 ± 20.4 years. Nutritional assessment was performed at 7, 15 and 21 days and was compared with a control group (n = 30). In 21 patients the burned body surface area was 20%-50% and in four patients it was greater than 50%. A mean decrease in energy supply of ~40% versus the calculated theoretical value was found in the three periods: 1,186 ± 32; 1,117 ± 589 and 1,331 ± 578 kcal. In the first 15 days antioxidant ingestion was slightly lower than the recommended daily allowance for vitamin C: 60 mg versus 57 ± 32, 57 ± 53 and 75 ± 53 mg, and was lower during the entire period for vita-min E: 10 mg versus 5.0 ± 2.9; 4.5 ± 3.0 and 5.3 ± 3.4 mg; selenium: 40 µg versus 22.8 ± 13.7; 22.5 ± 9.8 and 25.7 ± 11.2 µg and zinc: 12 mg versus 7.3 ± 3.0, 6.8 ± 4.8 and 8.4 ± 5.3 mg. Taurine ingestion decreased on day 15 and significantly increased on day 21: 65.7 ± 30 mg, 50.9 ± 25 and 72.0 ± 29 mg (p < 0.05). Ingestion of total polyamines did not differ significantly from the values observed in the control group and were as follows: day 7, total 45.2 ± 23.0 umol, putrescine 16.7 ± 10.2, spermidine 13.5 ± 7.6 and spermine 13.6 ± 8.8; day 15: total 41.1 ± 38.5 and 14.9 ± 4.0, 11.7 ± 9.4 and 10.89 ± 9.0; day 21: total 39.1 ± 35.3 and 15.4 ± 16.9, 12.3 ± 11.4 and 17.3 ± 16.8 umol, respectively.
