[Various parameters of humoral and cellular immunity in children with iron deficiency].

Serum IgA, IgM and IgG as well as percentage of lymphocytes T and B in peripheral blood were determined in 50 children aged between 6 months and 3 years with iron deficiency anaemia. A significant decrease in lymphocyte T number in these children was found in comparison with control group of healthy children. Lymphocyte T count positively correlated with serum iron concentration. Moreover, a decrease in serum IgA and IgG was found in children with iron deficit.
