Впервые проведено комплексное исследование различных аспектов реактивности нейтрофилов при этой патологии, включая их способность к образованию активных форм кислорода и формированию внеклеточных ловушек (нетоз). Результаты показали значительные изменения в функциональной активности нейтрофилов у пациентов с наследственным сфероцитозом вне гемолитического криза, в частности — повышенную способность к образованию активных форм кислорода и усиленный нетоз. Особенно выраженная активация нетоза наблюдалась у пациентов младшей возрастной группы (до 5 лет). Выявлены корреляции между показателями нетоза и количеством эритроцитов и лейкоцитов в периферической крови пациентов. Исследование вносит значительный вклад в изучение взаимосвязи между патологией эритроцитов и функциональным состоянием нейтрофилов, что ранее не было подробно изучено в контексте наследственного сфероцитоза.</p></abstract><trans-abstract xml:lang="en"><p>This study investigates the functional activity of peripheral blood neutrophils in children with hereditary spherocytosis − one of the most common forms of congenital hemolytic anemias. For the first time, a comprehensive examination of various aspects of neutrophil reactivity in this pathology was conducted, including their ability to form reactive oxygen species and neutrophil extracellular traps (NETosis). The results revealed significant changes in neutrophil functional activity in patients with hereditary spherocytosis outside of hemolytic crisis, particularly an increased capacity for reactive oxygen species formation and enhanced NETosis. Notably pronounced NETosis activation was observed in patients of the younger age group (up to 5 years). Correlations were identified between NETosis indicators and the number of erythrocytes and leukocytes in patients' peripheral blood. This study contributes significantly to understanding the relationship between erythrocyte pathology and neutrophil functional status, an aspect that had not been previously studied in detail in the context of hereditary spherocytosis.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>наследственный сфероцитоз</kwd><kwd>нейтрофилы</kwd><kwd>нетоз</kwd><kwd>эритроциты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hereditary spherocytosis</kwd><kwd>neutrophils</kwd><kwd>NETosis</kwd><kwd>erythrocytes</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">Ciepiela, O.
