Срок гестации составил 27 (26–28) недель, масса тела при рождении – 950 (795–1185) граммов. Оценка уровней противоспалительных маркеров (С-реактивного белка (СРБ), прокальцитонина (ПКТ) и интерлейкина-6 (ИЛ-6)) осуществлялась в динамике неонатального периода. Статистический анализ проводили с использованием MedCalc, Statistica 10.</p></sec><sec><title>Результаты исследования</title><p>Результаты исследования: установлено значимое отличие уровней ИЛ-6 (р &lt; 0,001), СРБ (р = 0,014), ПКТ (р = 0,030) в 1-е сутки жизни у глубоко недоношенных новорожденных с инфекционно-воспалительными заболеваниями по сравнению с пациентами с респираторным дистресс синдромом. На 3–10-е сутки значимо различались уровни СРБ (р &lt; 0,001) и ПКТ (р &lt; 0,001). В 1-е сутки наибольшей диагностической значимостью обладал уровень ИЛ-6 (AUC 0,949, чувствительность – 77,1 %, специфичность – 98,9 %), на 3–10-е сутки – уровни СРБ и ПКТ.</p></sec><sec><title>Заключение</title><p>Заключение: Проведенное исследование провоспалительных маркеров (СРБ, ПКТ, ИЛ-6) продемонстрировало значимость данных биомаркеров при прогнозировании и раннем выявлении инфекционно-воспалительных заболеваний у крайне незрелых недоношенных пациентов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose</title><p>Purpose: to evaluate the diagnostic value of pro-inflammatory markers in extremely immature premature newborns with infectious and inflammatory diseases.</p><p>Materials and methods of the study: data from 49 newborns with extremely low and very low body weight (ELBW and VLBW) treated in the intensive care unit were retrospectively studied. Gestational age was 27 (26–28) weeks, birth weight was 950 (795–1185) grams. The levels of pro-inflammatory markers (c-reactive protein (CRP), procalcitonin (PCT) and interleukin-6 (IL-6)) were assessed over the course of the neonatal period. Statistical analysis was performed using MedCalc, Statistica 10.0.</p></sec><sec><title>Study results</title><p>Study results: A significant difference was established in the levels of IL-6 (p &lt; 0.001), CRP (p = 0.014), PCT (p = 0.030) on the 1st day of life in very premature newborns with infectious and inflammatory diseases compared to patients with respiratory distress syndrome. On days 3–10, the levels of CRP (p &lt; 0.001) and PCT (p &lt; 0.001) differed significantly. On 1st day, the level of IL-6 had the greatest diagnostic significance (AUC 0.949, sensitivity – 77.1 %, specificity – 98.9 %), on days 3–10 – the content of CRP and PCT. Conclusion: The study of pro-inflammatory indicators (CRP, PCT, IL-6) demonstrated the significance of these biomarkers in predicting and early detection of infectious and inflammatory diseases in extremely immature premature patients.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>недоношенные новорожденные</kwd><kwd>прокальцитонин</kwd><kwd>С-реактивный белок</kwd><kwd>интерлейкин-6</kwd><kwd>инфекционно-воспалительные заболевания</kwd></kwd-group><kwd-group xml:lang="en"><kwd>premature newborn</kwd><kwd>procalcitonin</kwd><kwd>C-reactive protein</kwd><kwd>interleukin-6</kwd><kwd>infectious-inflammatory diseases</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">Диагностическая точность пресепсина, прокальцитонина и С-реактивного белка у новорожденных с ранним неонатальным сепсисом: одноцентровое проспективное исследование / Е.
