Выраженность токсемии зависит от площади и глубины поражения, резорбции продуктов распада тканей, формирования системного воспалительного ответа. У пострадавших с глубокими ожогами в 15% случаев развивается сепсис. Патогенез критических состояний тесно связан с функциональной активностью миелоидных клеток, в том числе нейтрофильных гранулоцитов (НГ). Определение характера нарушений функции НГ у пострадавших с ОжТ важно как для прогноза развития септических осложнений, так и формирования целевой терапии. Целью настоящего исследования явилось изучение функций нейтрофилов у пострадавших с тяжелой ожоговой травмой и определение ранних предикторов ожогового сепсиса. Обследованы 53 пострадавших с тяжелой ожоговой травмой ОжТ в возрасте 43 (32-52) года; площадь повреждения составляла 43 (17-63)% поверхности тела с площадью глубоких ожогов 17 (13-27)%. Тяжесть ОжТ оценивали с помощью индекса Франка, величина которого составила 74 (62-89) у. е. В процессе исследования были выделены две группы пострадавших в зависимости от развития генерализованных бактериальных осложнений: 24 человека без сепсиса и 29 человек с сепсисом. Развитие ожогового сепсиса определяли по критериям американской ожоговой ассоциации (ABA, 2007). Исследования проводили при поступлении, на 1-е, 3-и, 5-е, 10-е и 20-е сутки ожоговой болезни. Определяли количество форменных элементов крови и лейкограмму; фенотипические и активационные маркеры гранулоцитов крови иммуноцитохимическим методом с использованием моноклональных антител: рецепторы адгезии – β2 интегрины (CD18+), CD14+НГ (NCL-CD14), дефенсин+ НГ (human neutrophil peptides, HNP 1-3), (Def+НГ); концентрацию в крови растворимых дефенсинов (sDеf) (Human HNP1-3), IL-6, IL-8 методом ИФА; содержание прокальцитонина; люминолопосредованную спонтанную и индуцированную зимозаном хемилюминесценцию НГ. Результаты исследования показали связь между количеством НГ, содержащих антимикробные пептиды, количеством НГ, экспрессирующих адгезионные молекулы СD18+, активацией окислительного метаболизма, гиперпродукцией IL-6 и развитием сепсиса у пострадавших с тяжелой ОжТ и тяжестью ожоговой травмы.</p><p> </p></abstract><trans-abstract xml:lang="en"><p>Severe burn injury (BI) is accompanied by disturbed microcirculation, water-electrolyte and acidbase imbalance within 2-3 days after the accident, and the development of toxemia within 4-12 days. The severity of toxemia depends on the area and depth of the lesion, resorption of tissue decay products, and development of a systemic inflammatory response syndrome. In the patients suffering with deep BI sepsis, it develops in 15% of cases. Pathogenesis of critical conditions is related to the functional activity of myeloid cells, including neutrophilic granulocytes (NG). Тhe determination of NG’s dysfunctions in patients with BI is important, both for prediction of septic complications and administration of rational therapy. The aim of our work was to study the functions of neutrophils in patients with severe BI and to determine early predictors of burn-associated sepsis. The study involved 53 patients with severe BI at the mean age of 43 years (32 to 52); the area of damage was 43% (17 to 63) of the body surface, with deep-burn area of 17 (13 to 27) %. The severity of BI was assessed using the Frank index, at the average value of 74 conventional units (62 to 89). Тwo groups of patients were identified: 24 persons without sepsis, and 29 people with sepsis and severe sepsis. The studies were carried out upon admission, on the 1st, 3rd, 5th, 10th , and 20th day of the burn disease. We determined the numbers of NGs expressing CD18+, CD14+, defensin+; serum contents of soluble defensins (sDеf), IL-6, IL-8 levels (ELISA); procalcitonin, as well as luminol-mediated spontaneous аnd induced NG chemiluminescence. Тhe results of this study showed a relationship between the amounts of NGs containing antimicrobial peptides, contents of NGs expressing CD18+ adhesion molecules, activation of oxidative metabolism, IL-6 overproduction, and development of sepsis in patients with burn injury, as well as with severity of burn trauma.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>тяжелая ожоговая травма</kwd><kwd>функции нейтрофилов</kwd><kwd>сепсис</kwd></kwd-group><kwd-group xml:lang="en"><kwd>burn injury</kwd><kwd>severe</kwd><kwd>neutrophil function</kwd><kwd>sepsis</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">Алексеев А.А., Крутиков М.Г., Яковлев В.П.
