Purpose: to evaluate the functional status of the immune system in children of various age with diagnosed iron deficiency anemia.
Patients and methods. The study involved 106 children under the age of 3 years with diagnosed iron deficiency anemia (IDA). Were analyzed thoroughly factors of development of sideropenic conditions and probable immunodeficient disease. Activity of systemic immune response development in children with anemia was monitored by indexes of cellular (T-, B-lymphocytes) and humoral immunity (Ig A, M, G).
Results. In young children with IDA was founded significant reduction in the total number of T- lymphocytes (CD3+), CD22+, CD16+, CD4+ and CD8+, compared with values of the control group, both as in the case of presence of an infectious inflammatory disease, and in the case of its absence. Also was diagnosed decreasing of absolute and relative amount of T- lymphocytes and their subpopulations, and that indicated to some extent of reduction of both helper and suppressor activity of cellular immunity. Analyzis of immunoglobulins values in the serum of patients with IDA without any concomitant acute infectious disease showed specific dysimmunoglobulinaemia, which was associated with significantly low levels of IgG, IgA, and normal values of Ig M. However, in the case of IDA, combined with acute respiratory disease, was tracked significant increasing in Ig A and Ig M values, with decreased level of IgG. Significant difference between level of immunoglobulin A (p <0.05) and M with the same indexes of the group of children without any acute disease indicates for the activation of the humoral response while presence of infectious pathology.
Conclusions. In young children with IDA was founded significant reduction in the total number of T- lymphocytes and their subpopulations, and that indicated reduction of both helper and suppressor immunity activity, and can serve as proof of the violation in rates of physiological maturation and differentiation of the immune response. The last one is indicated by significant deficit of Ig G in children with IDA, which shows late immune start in patients with anemia, regardless of existing of some infectious disease or without it.
Key words: iron deficient anemia, infants, toddlers, immunity, children.
