The severity of acute respiratory infections in children during the first 3–6 months of life and the development of complications may be due to the peculiarities of the immune system, its development after birth. Of particular influence on these processes, have particular power, in particular the presence and duration of breastfeeding. The objective was to study the features of the immune response of peripheral blood in conjunction with the duration of breast-feeding.
The study involved 60 children aged 1 to 3 years, who was being treated in the infectious department of children's hospital with a diagnosis of acute respiratory disease. They were divided according to age into 3 groups: 1 group included 20 children aged up to one year, 2 group – 20 children from year to 2 years and 3 group – 20 children aged 2 to 3 years. We analyzed the basic changes of the blood and the relationship between the absence / presence of breast-feeding for at least the first 6 months of life and gave the characteristics of the analysis of the deviations.
The results of blood tests showed some of basic changes of hematological indicators. It was found that the incidence of inflammatory changes and increases of toxicity grow with the age of the child and connected with a decrease in the frequency of breastfeeding. Feeding breast milk to the age of a year increases the probability of the improvements of the immune response in the form of higher levels mainly of neutrophils.
