N-терминальный фрагмент мозгового натрийуретического пептида В-типа (NT-proBNP) является общепризнанным сердечно-сосудистым маркером кардиального происхождения. Причем в последнее время было показано, что провоспалительные стимулы также могут влиять на его секрецию. Целью исследования стала оценка сывороточной концентрации NT-proBNP в сопоставлении с составом клеток иммунной системы в эпикардиальной жировой ткани (ЭЖТ) и цитокиновым профилем у пациентов с ИБС. В исследование вошли пациенты со стабильной ИБС и хронической сердечной недостаточностью II-III ФК по классификации Нью-Йоркской кардиологической ассоциации (NYHA) с показаниями для проведения операции аортокоронарного шунтирования (АКШ) (n = 10; в возрасте 59,5 (53,0-65,0) лет; 50% мужчины). Образцы ЭЖТ и подкожной жировой ткани (ПЖТ) получали в ходе планового аортокоронарного шунтирования (АКШ). Для исследования применяли иммуногистохимический метод окрашивания антителами к CD68, CD45, IL-1β и TNFα. Для подсчета клеток использовали световую микроскопию. Подсчет клеток проводился в 10 полях зрения при увеличении 400. Перед проведением оперативного вмешательства у пациентов производили взятие венозной крови утром натощак. Кровь центрифугировали при 1500 g, с последующим аликвотированием образцов сыворотки крови, которые хранились при температуре -40°С. Концентрации NT-proBNP, IL-1β, IL-6, IL-10, TNFα оценивали в сыворотке методом иммуноферментного анализа (ИФА). Мы выявили увеличение продукции IL-1β и TNFα в ЭЖТ в сравнении с ПЖТ. Уровень NT-proBNP превышал концентрацию 125 пг/мл у 4 пациентов и коррелировал с содержанием CD68+ макрофагов как в ЭЖТ, так и в ПЖТ (rs = 0,762; p = 0,010 и rs = 0,835; p = 0,003 соответственно). Концентрация NTproBNP положительно коррелировала с количеством CD45+ лейкоцитов (rs = 0,799; p = 0,006) и IL-1β+ клеток (rs = 0,705; p = 0,023) исключительно в ЭЖТ. Среди сывороточных маркеров, NT-proBNP был отрицательно связан с уровнем глюкозы натощак rs = -0,684; p = 0,029), и положительно в сывороточной концентрацией IL-6 (rs = 0,891; p = 0,001). Увеличение сывороточной концентрации NT-proBNP у пациентов с ИБС соответствует аккумуляции макрофагов в ЭЖТ, что ассоциируется с увеличением продукции IL-1β в ЭЖТ и коррелирует с метаболическими параметрами.</p><p> </p></abstract><trans-abstract xml:lang="en"><p>Coronary artery disease (CAD) is widely considered a chronic inflammatory disorder, and dysfunction of epicardial adipose tissue could be an important source of the inflammation. Amino-terminal fragment of pro-B-type natriuretic peptide (NT-proBNP) is a known marker of cardiovascular disorders of cardiac origin. Recent studies show that inflammatory stimuli may influence its secretion. Our purpose was to evaluate NT-proBNP serum concentration in relation to immune cell ratios in epicardial adipose tissue (EAT), and cytokine levels in the patients with stable CAD. Patients with stable CAD and heart failure classified into classes II–III, according to the New York Heart Association (NYHA) scale, scheduled for the coronary artery bypass graft (CABG) surgery, were recruited into the study (n = 10; 59.5 (53.0-65.0) y. o.; 50% males). The EAT and subcutaneous adipose tissue (SAT) specimens were harvested in the course of CABG surgery. Immunostaining with anti-CD68, anti-CD45, antiIL-1β and anti-TNFα monoclonal antibodies was performed to evaluate cell composition by differential counts per ten fields (400 magnification). Fasting venous blood was obtained from patients before CABG. Blood was centrifuged at 1500g, aliquots were collected and stored frozen at -40 °С until final analysis. Concentrations of NT-proBNP, IL-1β, IL-6, IL-10, TNFα were determined in serum samples by enzyme-linked immunosorbent assay (ELISA). We have found increased production of IL-1β and TNFα cytokines in EAT compared to SAT. Concentrations of NT-proBNP exceeded 125 pg/ml in 4 patients, and correlations between the CD68+ macrophage counts in both EAT and SAT samples (rs = 0.762; p = 0.010 and rs = 0.835; p = 0.003, respectively). NT-proBNP levels showed positive relations with CD45+ leukocyte counts (rs = 0.799; p = 0.006), and with IL-1β+ cell numbers (rs = 0.705; p = 0.023) in EAT samples only. As for the serum biomarkers, NT-proBNP levels showed negative correlation with fasting glucose levels (rs = -0.684; p = 0.029), and positive correlation with serum IL-6 concentrations (rs = 0.891; p = 0.001). Increased serum concentrations of NT-proBNP in CAD patients correlate with accumulation of macrophages in EAT, which is associated with increased production of IL-1β in EAT and correlates with some metabolic parameters.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>макрофаги</kwd><kwd>эпикардиальная жировая ткань</kwd><kwd>NT-proBNP</kwd><kwd>ишемическая болезнь сердца</kwd><kwd>воспаление</kwd></kwd-group><kwd-group xml:lang="en"><kwd>macrophages</kwd><kwd>epicardium</kwd><kwd>adipose tissue</kwd><kwd>NT-proBNP</kwd><kwd>coronary artery disease</kwd><kwd>inflammation</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Министерство науки и высшего образования</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>This work was completed within the framework of the fundamental research No. АААА-А15- 115123110026-3</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Altun I., Unal Y., Basaran O., Akin F., Emir G.K., Kutlu G., Biteker M.
