The paper presents data on relationships between the regional incidence of the autoimmune pathology of the thyroid gland among children in Russia and the contents of some microelements in their hair, namely those known to have an adjuvant effect on the immune system. The results relate to all Federal Districts of Russia in 2008-2017. А regression model of these relationships is proposed. It has been shown that the region-specific contents of iodine and mercury but not aluminium in the hair of children positively correlate with the regional incidence of Graves’ disease. Thus, an increase in the exposure to an essential microelement in excess of need, as well as an increase in the exposure of toxic trace elements, can adversely affect autoimmunity. The data are discussed in comparison with literature on this topic and in the context of predicting and preventing the risk of autoimmune thyroid disease in pediatrics, especially with regard to the optimal choice of vaccines. The issues related to the permissive effect of the various factors that form the mosaic of autoimmunity, on the resulting changes in reactivity are addressed. The bill for obligatory iodization of cooking salt in the Russian Federation is criticized because it does not take into account regional differences in the availability of trace elements.

Trace Element Deficiency

The level of 10 trace elements (As, Br, Co, Cu, Fe, Hg, Mg, Mn, Se, Zn) in infant tissues (5 cot deaths, 4 other causes) are presented. These levels are compared with the normal adult levels for the same area or with the levels presented in the literature. The concentrations of 5 trace elements (As, Cu, Hg, Mn, Se) in human milk and 4 brands of artificial milks are also given and the intake of these trace elements from human and artificial milk for infants up to the age of 6 months is calculated. It is concluded that some artificial milks contain less of some essential trace elements (e.g. Cu and Se) and are richer in toxic trace elements (e.g. Hg and As). The suggestion of deficiency of the reported trace elements as a cause of cot deaths is rejected.
