Одними из внесуставных проявлений ЮИА являются гематологические изменения в виде развития анемического синдрома. Цель исследования ‒ изучение изменений показателей эритроцитарного ряда крови и состояния обмена железа у детей с ЮИА в зависимости от формы и длительности заболевания. Проведен ретроспективный анализ медицинских карт стационарных пациентов детского возраста. Изучены показатели эритроцитарного ряда, включая определение количества эритроцитов, уровня гемоглобина, соотношения количества эритроцитов к объему крови, среднего объема эритроцита, среднего содержания гемоглобина в эритроците, средней концентрации гемоглобина в эритроците, а также распределение эритроцитов по длине в виде разницы между наибольшим и наименьшим размером эритроцитов и отклонение объема эритроцитов от средней величины. Состояние обмена железа оценивали по таким показателям, как содержание сывороточного железа, ферритина, трансферрина, латентная железосвязывающая способность сыворотки крови, общая железосвязывающая способность сыворотки, коэффициент насыщения трансферрина железом. У 18,7 % детей с ЮИА отмечено снижение гемоглобина до менее 120 г/л. Выявлено достоверное (р &lt; 0,001) снижение среднего содержания гемоглобина в эритроците у 37,9 % пациентов. В результате исследования было установлено, что снижение содержания железа в сыворотке крови обусловлено не только истинным железодефицитным состоянием (ЖДС), но и перераспределением запасов железа на фоне хронического аутоиммунного воспаления. При системной форме заболевания изменения латентного ЖДС более выражены. При длительном течении заболевания происходит нормализация эритроцитарных показателей. Длительность заболевания не оказывает влияния на феррокинетику и на изменение эритроцитарных показателей, что обусловлено развитием компенсации ЖДС на фоне проводимого лечения.</p><p> </p></abstract><trans-abstract xml:lang="en"><p>Juvenile idiopathic arthritis (JIA) is a systemic chronic disease. One of the extra-articular manifestations of JIA are hematological changes. The most common is anemia. The aim of the study was to explore the indicators of the red blood cells and the state of iron metabolism in children with JIA, depending on the form and duration of the disease. A retrospective analysis of the medical history of patients was carried out. The study of the indicators of the red blood cells consisted in determining the number of erythrocytes, the amount of hemoglobin, the ratio of the number of erythrocytes to blood volume, the average volume of erythrocytes, the average hemoglobin content in the erythrocyte, the average concentration of hemoglobin in the erythrocyte, as well as the distribution of red blood cells along the length in the form of the difference between the largest and smallest size of red blood cells and the deviation of the volume of red blood cells from the average value. The state of iron metabolism was represented by such indicators as the content of serum iron, ferritin, transferrin, latent iron-binding capacity of blood serum, total iron-binding capacity of serum, transferrin saturation coefficient with iron. In 18.7 % of children with JIA, a decrease in hemoglobin of less than 120 g/l was noted. There was a significant (p &lt; 0.001) decrease in the average hemoglobin content in the erythrocyte in 37.9 % of patients. As a result of the study, it was found that the decrease in the iron content in the blood serum is due not only to the true iron deficiency state, but also to the redistribution of iron reserves against the background of chronic autoimmune inflammation. In the systemic form of the disease, changes in the latent iron deficiency state are more pronounced. With a long course of the disease, normalization of red blood cell parameters occurs. The duration of the disease has no effect on ferrokinetics, which is due to the development of iron deficiency compensation against the background of ongoing treatment.</p><p> </p></trans-abstract><kwd-group xml:lang="ru"><kwd>анемия хронического заболевания</kwd><kwd>детский возраст</kwd><kwd>железодефицитная анемия</kwd><kwd>ювенильный идиопатический артрит</kwd><kwd>обмен железа</kwd></kwd-group><kwd-group xml:lang="en"><kwd>anemia of chronic disease</kwd><kwd>childhood</kwd><kwd>iron deficiency anemia</kwd><kwd>juvenile idiopathic arthritis</kwd><kwd>iron metabolism</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">Manners, P.
