Оценить и сравнить антропометрические и ранние постнатальные факторы, сроки развития анемии, проводимое лечение и показатели эритроидного ростка периферической крови у недоношенных детей в зависимости от срока гестации.Материал и методы. Проведено ретроспективное когортное исследование 110 недоношенных новорожденных с ранней анемией недоношенных, разделенных в зависимости от срока гестации при рождении на три группы: 1-я группа — до 28 нед. (n = 16); 2-я группа — 28—31 нед. (n = 63); 3-я группа — 32—37 нед. (n = 31). Проанализированы антропометрические параметры, наличие асфиксии при рождении, нуждаемость в искусственной вентиляции легких и ее длительность, проведенное лечение препаратами эритропоэтина и эритроцитными компонентами крови. Изучены показатели эритроидного ростка периферической крови на момент рождения и манифестации анемии. Статистические расчеты проведены в программной среде R, версия 4.3.Результаты. Результаты проведенного исследования свидетельствуют об отсутствии статистически значимых различий в сроках манифестации ранней анемии недоношенных у детей в зависимости от срока гестации. На момент манифестации данной патологии определяется тренд более низких значений концентрации гемоглобина при снижении гестационного возраста недоношенного ребенка. Также обнаружен тренд к снижению абсолютного количества эритроцитов при рождении с уменьшением срока гестации при отсутствии такового при анализе концентрации гемоглобина.Выводы. Гемотрансфузионная терапия у детей со сроком гестации менее 28 нед. является временной мерой коррекции анемии и не приводит к уменьшению степени тяжести этого состояния по сравнению с детьми более позднего гестационного возраста. Также установленные закономерности изменения количества эритроцитов и концентрации гемоглобина у недоношенных новорожденных при рождении указывают на преобладание нарушения пролиферативной активности клеток эритроидного ростка, но не процессов гемоглобинизации. Анализ показателей относительного количества ретикулоцитов с учетом наличия ранней анемии недоношенных указывает на отсутствие адекватной регенераторной способности эритроидного ростка костного мозга.</p></abstract><trans-abstract xml:lang="en"><p>Objective. To evaluate and compare anthropometric and early postnatal factors, time of anemia manifistation, treatment and peripheral blood erythroid indicators in premature infants depending on gestational age.Materials and methods. A retrospective cohort study was conducted of 110 premature newborns with early anemia of prematurity. The babies was divided depending on the gestational age at birth into 3 groups: group 1— up to 28 weeks of gestation (n = 16); group 2 — with a gestational age of 28—31 weeks (n = 63); group 3 — with a gestational age of 32—37 weeks (n = 31). We were analyzed anthropometric parameters, the presence of asphyxia at birth, the need for artificial ventilation of the lungs and its duration, treatment with erythropoietin preparations and erythrocyte blood components. We were studied the indicators of erythroid growth in peripheral blood at the time of birth and at the time of manifestation of anemia. Statistical calculations were carried out in the R statistical package, version 4.3.Results. The results of the study indicate that there are no statistically significant differences in the timing of manifestation of anemia of prematurity in children depending on the gestational age. We was also found a trend to a decrease in the absolute number of red blood cells at birth with a decrease in gestational age. We found absence of trend of hemoglobin concentration and gestational age. Аt the time of manifestation of anemia а trend of lower values of hemoglobin concentration is determined with a decrease in the gestational age of the premature baby.Conclusion. Blood transfusion therapy in children with a gestational age of less than 28 weeks is a temporary measure to correct anemia. Hemotransfusions does not reduce the severity of this condition compared to children of later gestational age. Also, the established patterns of changes in the number of erythrocytes and hemoglobin concentration in premature infants at birth indicate the predominance of a violation of the proliferative activity of erythroid cells, but not the processes of hemoglobinization. The analysis of the indicators of the relative number of reticulocytes, taking into account the presence of anemia of anemia of prematurity, indicates the lack of adequate regenerative ability of the erythroid sprout of the bone marrow.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>анемия недоношенных</kwd><kwd>характеристика эритроидного ростка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>anemia of prematurity</kwd><kwd>characteristics of the erythroid germ</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">National, regional, and global estimates of preterm birth in 2020, with trends from 2010 : a systematic analysis / E.
