Influence of breast feeding on vitamin E concentration in plasma of infants with infection
Vitamin E together with selenium-dependent glutathione peroxidase and catalase form the main antioxidative system of human cells. Vitamin E is indispensable nourishment component, since it cannot be synthesized by human cells. Therefore appropriate diet is an important factor determining antioxidave abilities of the organism. The aim of the study was to estimate feeding type influence on vitamin E concentration in blood plasma of infants hosptalized in Infants' Department. Study group consisted of 42 children (18 girls and 24 boys) aged 1 - 12 months, hospitalized due to pneumonia, otitis media, urinary tract infection, diarrhoea or sepsis. Children were divided into three groups concerning the type of feeding: 1. children feed with modified milk-30 (71.43%), 2. children feed with mother's milk-7 (16.67%), 3. children feed in mixed way - 5 (11.9%). Vitamin E plasma concentration was estimated by fluorometric method modified by Hansen and Warnick. Results were given in μg/mL. Statistical analysis was performed using NIR post-hoc test. P<0.05 was considered as statistically significant. We found statistically higher vitamin E concentration in blood plasma of infants fed only with mother's milk (25.28±10.33, range: 11.4-40 μg/mL) compared to the children fed with modified milk (18.56±6.74, range: 7.6-30 μg/mL) and these fed in mixed way (16.15±5.14, range: 11.8-23.5 μg/mL). Vitamin E concentration was the highest in blood plasma of infants fed only with mother's milk, which showed beneficial influence of breast feeding on vitamin E plasma concentration in infants with infection.
