Изучение белокпродуцирующей и липидвысвобождающей способности нейтрофилов и ее клинической значимости у больных ИБС.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Обследованы 25 пациентов с артериальной гипертензией без клинических и ультразвуковых манифестаций атеросклероза; 47 больных ИБС со стабильной стенокардией напряжения, а также 19 больных первичной нестабильной стенокардией. Группа сравнения — 33 практически здоровых лица. В сыворотке крови посредством иммуноферментного анализа оценивалась концентрация С-реактивного белка (СРБ), липопротеина а (ЛПа), VII фактора свертывания крови (VIIф), дефензинов-альфа (1–3), интерлейкина-6 (ИЛ-6), интерлейкина-8 (ИЛ-8), фактора некроза опухоли альфа (ФНО-альфа). Из периферической крови в присутствии декстранов выделялись лейкоциты, представленные преимущественно нейтрофилами, которые в дальнейшем культивировались, в лейкоцитарных супернатантах оценивалось содержание СРБ, ЛПа, дефензинов-альфа (1–3), VIIф, а также липидвысвобождающей способности лейкоцитов (ЛВСЛ) по методике А. В. Туева и В. Ю. Мишланова. Проводились ангиографическое исследование, дуплексное сканировавние артерий и эхокардиография.</p></sec><sec><title>Результаты</title><p>Результаты. Установлено, что у больных на этапе доклинического атеросклеротического поражения способность лейкоцитов к образованию белково-липидных комплексов (БЛК), маркируемая величиной ЛВСЛ, практически не отличается от здоровых лиц, но уже на этой стадии атерогенеза выявлено увеличение их способности к продукции противомикробных пептидов —  дефензинов-альфа (1–3). У больных ИБС со стабильной стенокардией напряжения отмечено увеличение продукции лейкоцитами широкого спектра белков — дефензинов-альфа (1–3), VIIф, ЛПа и СРБ в сочетании с признаками системной воспалительной реакции, маркируемой высокими концентрациями СРБ, интерлейкина-6 и фактора некроза опухоли альфа в сыворотке крови. На данном этапе атерогенеза величина ЛВСЛ значимо отличается от значений, характерных для здоровых лиц. Показано, что чем больше значение ЛВСЛ, тем выше у этих больных функциональный класс хронической сердечной недостаточности (R = 0,4; p = 0,02). У больных ИБС с первичной нестабильной стенокардией выявлена максимальная величина ЛВСЛ, а у пациентов с ультразвуковыми признаками нестабильности бляшек —  высокие концентрации СРБ в нейтрофильных супернатантах. Корреляционный анализ выявил, что у больных ИБС средний процент стеноза коронарных артерий, по данным ангиографии, напрямую взаимосвязан с величиной ЛВСЛ (R = 0,7; p = 0,03) и сывороточной концентрацией ФНО-альфа (R = 0,5; p = 0,03), а количество клинически значимых стенозов — с величиной ЛВСЛ (R = 0,4; p = 0,04) и концентрацией в супернатантах VIIф (R = 0,5; p = 0,04).</p></sec><sec><title>Заключение</title><p>Заключение. Величина ЛВСЛ, содержание СРБ и дефензинов-альфа в лейкоцитарных супернатантах у больных ИБС взаимосвязаны с тяжестью и активностью атеросклеротического поражения артерий, что подтверждается результатами обследования больных на этапе доклинического, клинически манифестного стабильного и нестабильного атеросклеротического поражения.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose</title><p>Purpose. The study of protein-producing and lipid-releasing ability of neutrophils and its clinical significance in patients with IHD.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. 25 patients with arterial hypertension without clinical and ultrasound manifestations of atherosclerosis were examined; 47 patients with coronary artery disease with stable angina, as well as 19 patients with unstable primary angina. The comparison group — 33 healthy persons. In the serum, enzyme-linked immunosorbent assay was used to evaluate the concentration of C-reactive protein (CRP), lipoprotein a (LPa), VII coagulation factor VII (VIIf), defensins-alpha (1–3), interleukin-6 (IL-6), interleukin-8 (IL-8), tumor necrosis factor alpha (TNF-alpha). Leukocytes, predominantly represented by neutrophils, which were further cultivated, were excreted from peripheral blood in the presence of dextrans; the levels of CRP, LPa, defensins-alpha (1–3), VIIf, and lipid-releasing ability of leukocytes (LRAL) were assessed according to the method of A. V. Tuev and V. Yu. Mishlanov. An angiographic study, duplex scanning arteries, and echocardiography were performed.</p></sec><sec><title>Results</title><p>Results. It has been established that in patients at the stage of preclinical atherosclerotic lesion, the ability of leukocytes to form protein-lipid complexes (PLC), marked by LRAL, practically does not differ from healthy individuals, but already at this stage of atherogenesis an increase in their ability to produce antimicrobial peptides — defensins-alpha (1–3). In patients with coronary artery disease with stable angina pectoris, an increase in leukocyte production of a wide range of proteins — defensins-alpha (1–3), VIIf, LPA and CRP in combination with signs of a systemic inflammatory reaction, marked by high concentrations of CRP, interleukin-6 and tumor necrosis factor alpha in serum, was noticed. At this stage of atherogenesis, the value of LRAL is significantly different from the values of healthy individuals. It is shown that the higher the LRAL value, the higher the functional class of chronic heart failure in these patients (R = 0.4; p = 0.02). In patients with coronary artery disease with primary unstable angina, the maximum LRAL value was detected, and in patients with ultrasound signs of plaque instability, high concentrations of CRP in neutrophilic supernatants were found. Correlation analysis revealed that, in patients with coronary artery disease, the average percentage of coronary artery stenosis, according to angiography, is directly related to the LRAL value (R = 0.7; p = 0.03) and the serum concentration of TNF-alpha (R = 0.5; p = 0.03), and the number of clinically significant stenoses — with the magnitude of LRAL (R = 0.4; p = 0.04) and the concentration in supernatants VIIf (R = 0.5; p = 0.04).</p></sec><sec><title>Conclusion</title><p>Conclusion. The LRAL value, CRP and defensin-alpha content in leukocyte supernatants in IHD patients are interconnected with the severity and activity of atherosclerotic lesion of arteries, which is confirmed by the results of examination of patients at the stage of preclinical, clinically manifest stable and unstable atherosclerotic lesion.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>атеросклероз</kwd><kwd>нейтрофилы</kwd><kwd>врожденный иммунитет</kwd><kwd>воспаление</kwd><kwd>ишемическая болезнь сердца</kwd></kwd-group><kwd-group xml:lang="en"><kwd>atherosclerosis</kwd><kwd>neutrophils</kwd><kwd>innate immunity</kwd><kwd>inflammation</kwd><kwd>coronary heart disease</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">Baetta R., Corsini A.
