Abstract
Objective. The aim of the work is to investigate the relationship between the indices of the cellular and humoral components of immunity, the absolute and relative quantity of immunocompetent blood cells in children infected in utero. Material and methods. 17 children aged 3 months to one year were divided into two groups: 1) control (n = 7); 2) in utero infected (n = 10). The study of blood counts and immune homeostasis was carried out from a single portion of heparinized venous blood taken from the ulnar vein of children with the permission of mothers. The determination was made by conventional methods [8-10]. Statistical processing of the results of the studies was carried out using standard methods for the program Statistica-6.0. To determine the statistical significance, the t-test of the Student was used. Results. In children with intrauterine infection, the absolute number of lymphocytes decreases 15.3%, the relative amount 14.3%, the relative amount of monocytes 83.9%, the ESR 65.0%, the index of nonspecific resistance - 50.0%. The latter testifies that the VUI is formed against a background of the reduction of factors and mechanisms of nonspecific anti-infectious protection. At the same time, the number of hemoglobin in children with UTI increases 15.7%, the relative number of stab neutrophils 25.9%, segmented leukocytes 34.1%, eosinophils 54.5%. The values of most immunohematological indices and coefficients are increasing: the leukocyte index increased by 2.4 times, the neutrophilic lymphocyte coefficient 52.9%, the leukocyte shift index 63.8%, and the index of immune reactivity 66.1%. An increase in intoxication after a leukocyte intoxication index 59.5% and a leucocyte index (Ya.Ya.Kalf-Kalifa) 28.6% was established. In this case, the absolute and relative number of leukocytes practically does not change. Conclusion. VUI in children aged 3 months to one year occurs and proceeds against a background of immunodeficiency.
