[Importance of immunoglobulins and nutrition in infections in neonates].
The purpose of the study was an estimation of the immunoglobulin serum and the way of nutrition of a new-born child at the beginning of bacterial infections during the first month of life. 120 new-born children (infantiles) of both sexes was prospectively studied, who were born in the Gynecology-obstetrician clinic in Tuzla, in the period from March-May 2000 year. On the base of mothers SES during the pregnancy, new-born children were separated in two groups. Group A was formed of 60 new-born children (32 female and 28 male), mothers had good SES during the pregnancy, and concentration of serum immunoglobulin G (IgG) examined from cords blood, from 10.02 to 17.58 g/L (X 14.48 g/L +/- 1.87). Group B was formed of 60 new-born children (27 female and 33 male), with bad mothers SES and with concentration of IgG from 6.80 to 13.01 g/L (X 10.62 g/L +/- 1.49). Immunoglobulins M and immunoglobulins A were negative in both groups of children. During the first month of life it was studied the way of nutrition and health condition of each new-born child. New-born children with bad mothers SES during the pregnancy, with low values of IgG and who were on the artificial food (nutrition), were showing with the significant difference (p < 0.001) in bacterial infections, comparing with the group who had good IgG. The new-born children with natural nutrition, despite the lower concentration of IgG, were protected from severe bacterial infections.
