Background. Human milk contains considerable number of growth factors, including epidermal growth factor (EGF) and insulin-like growth factor-1 (IGF-1). There are no data comparing the EGF and IGF-1 levels in the serum and milk of breast-feeding women. Therefore, the aim of our study was to assess a possible relationship between the concentrations of these growth factors. Material and methods. Thirty-nine women in child-birth were included in the study. Ali women provided blood and milk samples during the first six hours after delivery. EGF (by immunoenzymatic method) and IGF-1 (by radioimmunossay method) concentrations were measured in both media. Results. EGF breast milk concentrations ranged from 3.18 to 4.51 ng/ml and on average were significantly higher (p < 0.0001) than those found in the women’s serum (front 0.02 to 0.13 ng/ml). The opposite distribution was found for IGF-1 levels. Its milk concentrations ranged from 8.8 to 61.9 ng/ml and on average were significantly lower (p < 0.0001) than the serum concentrations (from 192.6 to 595.3 ng/ml). No correlation was found between the serum and milk concentrations of both growth factors. Conclusion. EGF seems to be synthesized locally in mammary glands, whereas IGF-1 probably permeates into the milk from the vascular bed.

Background. In case of shortage of breast milk despite proper lactation care or the poor state of the mother’s health, breast milk from human milk bank is recommended for feeding preterm infants. Objective. This study retrospectively evaluated the first year of the operation of the Regional Human Milk Bank. Material and methods. Data concerning donors was collected in the human milk bank during the cooperation. The clinical characteristics of the recipients was made on the basis of medical documentation from the Holy Family Hospital in Warsaw, Poland. Analysis of nutritional value was performed with the human milk analyzer (MIRIS AB). Results. In the first year of activity, 45 voluntary donors established cooperation, donating from 650 to 32030 ml of human milk. The content of nutrients in milk provided by donors was variable - protein 0.4-1.5 g / 100 ml, fat 1.1-7.4 g / 100 ml, carbohydrates 6.3-7.9 g / 100 ml. The average length of using donated human milk was 4 days and the average volume of milk for one infant was 282 ml. Conclusions. The donor profiles have a significant impact on the milk composition form HMB. The nutritional value can be improved by recruitment donors from mothers that gave birth prematurely and by beginning donation at earlier stages of lactation as soon as lactation is stabilized. In case of shortage of mothers own milk the immediate implementation of donors milk as a short-term support can significantly reduce the food intolerance incidence in the group of prematurely born infants
