При колонизации кости S. aureus остеобласты, остеоциты и макрофаги секретируют хемоаттрактанты и цитокины, инициирующие приток к месту инфекции большого количества НГ, которые в свою очередь секретируют цитокины, создавая воспалительную микросреду, способствующую образованию остеокластов резорбирующих кость. Известно, что цитокин-активируемые НГ претерпевают функциональные и фенотипические изменения. В этой связи интерес представляет выявление цитокинов, приводящих к трансформации фенотипа НГ в антигенпрезентирующие клетки (АПК) при ОГО. Цель исследования – определить уровни нейтрофил-ассоциированных сывороточных цитокинов IL-8, IL-17A, TNFα, IFNγ и их взаимосвязь с количественными и фенотипическими характеристиками субпопуляций CD66b+CD16+CD33+HLA-DR-, CD66b+CD16+CD33+HLA-DR+НГ при местноочаговой и септико-пиемической формах ОГО у детей.</p><p>Исследованы 28 детей 8-15 лет с ОГО: группа 1 – 20 детей с местноочаговой формой; группа 2 – 8 детей с септико-пиемической формой; группа сравнения – 13 условно здоровых детей. Определяли количество НГ субпопуляций CD66b+CD16+CD33+HLA-DR+, CD66b+CD16+CD33+HLA-DR-, плотность экспрессии рецепторов (MFI) (FC 500, МкАт Beckman Coulter, США); сывороточные цитокины IL-8, IL-17A, TNFα, IFNγ ИФА (ASCENT, Финляндия), тест-системы Cloud-Clone Corp. (США).</p><p>Показано появление в периферической крови (ПК) детей с различными формами тяжести ОГО двух активированных субпопуляций: СD66b+CD16+CD33+HLA-DR+ с фенотипом АПК, способных презентировать суперантиген S. aureus Т-лимфоцитам и субпопуляция с высокой цитотоксической активностью СD66b+CD16+CD33+HLA-DR- на фоне высоких концентраций сывороточных цитокинов IFNγ, IL-17 и повышенного уровня TNFα. Исходя из того, что степень активации НГ коррелирует со степенью воспалительного разрушения тканей, в том числе костной ткани, определение уровня IFNγ, IL-17 может быть полезным для оценки степени тяжести ОГО, а также для возможного контроля за течением инфекционно-воспалительных процессов, происходящих в костной ткани.</p><p>Принимая во внимание ведущую роль НГ в реализации различных воспалительных реакций, определение экспрессии HLA-DR, с целью детекции появления в ПК пациентов субпопуляции АПК-НГ, может иметь диагностическое значение не только при ОГО, но и при других тяжелых инфекционно-воспалительных заболеваниях.</p></abstract><trans-abstract xml:lang="en"><p>Dysfunctions of the immune system, in turn, of neutrophil granulocytes (NG), are the cause of the emergence and progression of the focus of infection in bone tissue and bone marrow in acute hematogenous osteomyelitis (AHO). When colonizing bones, S. aureus, osteoblasts, osteocytes and macrophages secrete chemoattractants and cytokines, which initiate the influx of large amounts of NG into the site of infection, which, in turn, secrete cytokines and form an inflammatory microenvironment that promotes the formation of osteoclasts that resorb bone. It is known that NG activated by cytokines undergo functional and phenotypic changes. In this regard, detecting the cytokines that lead to the transformation of the NC phenotype into an antigen-presenting cell (APC) in AHO is of interest. Goal, to determine the levels of neutrophil-associated serum cytokines IL-8, IL-17A, TNFα, IFNγ and their relationship with numerous and phenotypic characteristics of subpopulations CD66b+CD16+CD33+HLA-DR-, CD66b+CD16+CD33+HLA-DR+NG in localized and septicopyemic forms of CSO in children.</p><p>Children (N = 28) aged 8-15 years with AHO were studied: group 1 – 20 children with a localized form; group 2 – 8 children with septicopyemic form; and a comparison group of 13 conditionally healthy children. The number of NG subpopulations CD66b+CD16+CD33+HLA-DR+, CD66b+CD16+CD33+HLA-DR-, receptors mean expression intensity (MFI) (FC 500, mAb Beckman Coulter, USA); serum cytokines IL-8, IL-17A, TNFα, IFNγ ELISA (ASCENT, Finland), test systems Cloud-Clone Corp. (USA).</p><p>The appearance of two activated subpopulations in the peripheral blood (PB) of children with various forms of AHO severity were found: CD66b+CD16+CD33+HLA-DR+ with the APC phenotype, capable of presenting the S. aureus superantigen for T lymphocytes and a subpopulation with high cytotoxic activity CD66b+CD16+CD33+HLA-DR- while concentrations of serum cytokines IFNγ, IL-17 are high and levels of TNFα are increased. Due to the fact that the NG activation range correlates with the range of inflammatory tissue damage, including bone tissue, determination of the level of IFNγ, IL-17 can be useful for assessing the severity of AHO, and also possibly for monitoring infectious and inflammatory processes occurring in the bone tissue.</p><p>Taking into account the leading role of NG in various inflammatory reactions, determining the expression of HLA-DR, in order to identify the manifestation of the APC-NG subpopulation in peripheral blood, may have diagnostic value not only for AHO, but also for other manifestations of infectious and inflammatory diseases.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>нейтрофильные гранулоциты</kwd><kwd>антигенпредставляющая субпопуляция</kwd><kwd>цитокины</kwd><kwd>острый гематогенный остеомиелит</kwd><kwd>местноочаговая форма</kwd><kwd>септико-пиемическая форма</kwd><kwd>дети</kwd></kwd-group><kwd-group xml:lang="en"><kwd>neutrophil granulocytes</kwd><kwd>antigen-presenting subpopulation</kwd><kwd>cytokines</kwd><kwd>acute hematogenous osteomyelitis</kwd><kwd>localized form</kwd><kwd>septicopyemic form</kwd><kwd>children</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">Нестерова И.В., Чудилова Г.А., Тетерин Ю.В., Чичерев Е.А., Чапурина В.Н., Митропанова М.Н.
