Оценка выраженности спонтанного нетоза в периферической крови при сепсисе у детей периода ново-рожденности.</p><p>Характеристика детей и методы исследования. Изучена выраженность спонтанного нетоза у 12 детей с неонатальным сепсисом, находившихся на стационарном лечении в отделении реанимации новорожденных Городской детской больницы №1 Казани. Диагноз устанавливали на основании развития синдрома системного воспалительного ответа, повышения в крови концентрации С-реактивного белка более 1 мг/дл, наличия одного или нескольких очагов инфекции, развития органной дисфункции и выделения микроорганизма из венозной крови.</p></sec><sec><title>Результаты</title><p>Результаты. Установлено, что начальный период неонатального сепсиса протекает на фоне активации нетоза. Это проявлялось обнаружением в периферической крови нейтрофильных внеклеточных ловушек, количество и процентное содержание которых было достоверно больше, чем в контрольной группе (p=0,02 и p=0,0007 соответственно). Наиболее высокие уровни нейтрофилов в состоянии нетоза (67 и 70%) оказались у 2 детей с септическим шоком, у которых отмечалась лейкопения (2,7·109/л и 2,8·109/л соответственно). Развитие абсолютной нейтропении (менее 2·109/л) и лейкопении (менее 5·109/л) наблюдалось только у одного ребенка с септическим шоком. У 5 из 12 детей с неонатальным сепсисом имелась тромбоцитопения, которая у каждого четвертого была менее 100·109/л. При этом ни в одном случае не выявлены клинические проявления геморрагического синдрома и нарушения свертываемости крови.</p></sec><sec><title>Заключение</title><p>Заключение. Образование нейтрофильных внеклеточных ловушек служит одним из важнейших механизмов противоинфекционной защиты, направленных на купирование воспалительного процесса и достижение очищения внутренних сред организма.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective. To evaluate the severity of spontaneous netosis in peripheral blood in neonatal children with sepsis.</p><p>Characteristics of children and research methods. The researchers have studied the severity of spontaneous netosis in 12 neonates with sepsis who were hospitalized in the neonatal intensive care unit of the City Children’s Hospital No.1 in Kazan. The diagnose was based on a systemic inflammatory response syndrome, an increase in the concentration of C-reactive protein in the blood of more than 1 mg/dL, the presence of one or more foci of infection, the development of organ dysfunction, and the presence of a microorganism in venous blood.</p></sec><sec><title>Results</title><p>Results. It was found that the initial period of neonatal sepsis proceeds against the background of activation of netosis, which was manifested by neutrophil extracellular traps in the peripheral blood. Their quantity and percentage was significantly higher compared to the indicators of the control group (p=0.02 and p=0.0007 accordingly). The highest levels of neutrophils in the state of netosis (67% and 70%) were found in 2 neonates with septic shock and leukopenia (2.7·109/L and 2.8·109/L, respectively). Only one neonate with septic shock developed absolute neutropenia (less than 2•109/L) and leukopenia (less than 5·109 / L). Thrombocytopenia was noted in 5 of 12 neonates with sepsis, which was less than 100•109/L in every fourth child. At the same time, there were no clinical cases of hemorrhagic syndrome and blood clotting disorders.</p></sec><sec><title>Conclusion</title><p>Conclusion. The formation of neutrophilic extracellular traps is one of the most important mechanisms of anti-infective protection aimed at arresting the inflammatory process and clearing the internal media of the body.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>дети</kwd><kwd>неонатальный сепсис</kwd><kwd>врожденный иммунитет</kwd><kwd>нейтрофилы</kwd><kwd>нетоз</kwd></kwd-group><kwd-group xml:lang="en"><kwd>children</kwd><kwd>neonatal sepsis</kwd><kwd>innate immunity</kwd><kwd>neutrophils</kwd><kwd>netosis</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">Verma P., Berwal P.K., Nagaraj N.
