To study serum concentrations of trace and macro elements and their correlations in children and adolescents after antitumor therapy, depending on the presence or absence of caries.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study included 98 patients aged 4 to 17 years who were in remission after an antitumor therapy performed for acute leukemia or lymphomas. Patients with carious tooth lesions were included in group 1 (n = 34) and without caries – in group 2 (n = 64). We used inductively coupled plasma mass spectrometry to calculate the content of essential, conditionally essential and toxic elements in blood serum. The median and interquartile range were calculated, the Mann-Whitney U-test was applied to compare groups, and the Kendall rank correlation coefficient (τ) was calculated for tandem elements.</p></sec><sec><title>Results</title><p>Results. In both groups, the concentrations of the studied elements were within the reference ranges. In group 1, compared with group 2, higher concentrations of potassium, arsenic, iodine and boron and lower concentrations of lithium and tungsten (p &lt; 0.05) were noted. There were no differences in the concentration of phosphorus, calcium, magnesium, manganese, gold, silver, platinum, aluminum, beryllium, bismuth, cadmium, cobalt, chromium, copper, iron, mercury, lithium, molybdenum, nickel, rubidium, antimony, tin, vanadium, zinc, zirconium and thallium between the groups. Significant correlation coefficients in both groups were obtained for the iron/manganese tandem (τ = 0.24, p &lt; 0.05). Different values of τ were got for nickel/ manganese, cobalt/iron, manganese/phosphorus, beryllium/lithium tandems: τ = 0.342 and τ = 0.14; τ = 0.363 and τ = 0.033; τ = –0.111 and τ = –0.326; τ = –0.365 and τ = 0.42, respectively, for groups 1 and 2.</p></sec><sec><title>Conclusion</title><p>Conclusion. In patients in remission after antitumor therapy, an association of caries with an increase (within reference values) in the concentration of essential (potassium, iodine) and conditionally essential elements (arsenic, boron), a decrease in the concentration of lithium and tungsten; as well as a change in the ratio of nickel/manganese, cobalt/iron, manganese/ phosphorus and change the direction of the correlation in the beryllium/lithium tandem was revealed.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Цель</title><p>Цель. Изучить концентрацию микро- и макроэлементов в сыворотке крови и корреляционные связи между ними у детей и подростков после противоопухолевой терапии (ПОТ) в зависимости от наличия или отсутствия кариеса.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В исследование вошли 98 пациентов в возрасте от 4 до 17 лет, находившихся в ремиссии после ПОТ, проведенной по поводу острого лейкоза или лимфом. Пациенты, имевшие кариозное поражение зубов, вошли в группу 1 (n = 34), пациенты без кариеса составили группу 2 (n = 64). Расчет содержания эссенциальных, условно эссенциальных и токсических элементов сыворотки крови проводился с помощью масс-спектрометрии с индуктивно-связанной плазмой. Произведен расчет медианы и интерквартильного размаха, для сравнения групп применен U-критерий Манна – Уитни, для тандемов элементов вычислен коэффициент ранговой корреляции Кендалла (τ).</p></sec><sec><title>Результаты</title><p>Результаты. В обеих группах концентрации изученных элементов находились в пределах референсных значений. В группе 1 по сравнению с группой 2 отмечены более высокие концентрации калия, мышьяка, йода и бора и более низкие лития и вольфрама (p &lt; 0,05). Между группами не выявлено различий по концентрации фосфора, кальция, магния, марганца, золота, серебра, платины, алюминия, бериллия, висмута, кадмия, кобальта, хрома, меди, железа, ртути, лития, молибдена, никеля, рубидия, сурьмы, олова, ванадия, цинка, циркония и таллия. Значимые коэффициенты корреляции в обеих группах получены для тандема железо/марганец (τ = 0,24, p &lt; 0,05). Разные значения τ установлены для тандемов никель/марганец, кобальт/железо, марганец/фосфор, бериллий/литий: τ = 0,342 и τ = 0,14; τ = 0,363 и τ = 0,033; τ = –0,111 и τ = –0,326; τ = –0,365 и τ = 0,42 соответственно для групп 1 и 2.</p></sec><sec><title>Заключение</title><p>Заключение. У пациентов в ремиссии после противоопухолевой терапии выявлена ассоциация кариеса с повышением (в пределах референсных значений) концентрации эссенциальных (калий, йод) и условно эссенциальных элементов (мышьяк, бор), снижением концентрации лития и вольфрама; изменением соотношения никель/марганец, кобальт/железо, марганец/фосфор и направления корреляционной связи в тандеме бериллий/литий.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>макро- и микроэлементы</kwd><kwd>дисэлементоз</kwd><kwd>кариес</kwd><kwd>злокачественные новообразования</kwd><kwd>лечение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>macro and microelements</kwd><kwd>dyselementosis</kwd><kwd>caries</kwd><kwd>malignant neoplasms</kwd><kwd>treatment</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Florea A.M., Büsselberg D.
