Разработка метода регистрации циркулирующего в крови мономера С-реактивного белка (СРБ), а также изучение уровней изоформ СРБ - нативного пентамера С-реактивного белка (нСРБ) и мономера С-реактивного белка (мСРБ) - в крови пациентов со стабильной ишемической болезнью сердца (ИБС) и острым инфарктом миокарда.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Исследовали образцы плазмы крови, полученные от 14 пациентов с острым инфарктом миокарда на вторые - третьи сутки, 22 пациентов со стабильной ИБС и 11 здоровых добровольцев. Исследование проводили при помощи проточного цитофлу-ориметра FACSCantoll и набора функциональных частиц CytometricBeadArray (BDBiosciences, США). Использовали моноклональные антитела к СРБ (клоны MOH328 и MOH372 «ИМТЕК», Россия; клон 8С8, (Sigma-Aldrich, США), поликлональные антитела к СРБ GAH-FITC («ИМТЕК»), нативный СРБ («ИмТеК») и рекомбинантный мономерный СРБ (получен в дар от доктора L. Potempa).</p></sec><sec><title>Результаты</title><p>Результаты. Разработана тест-система, позволившая определить уровень мономера СРБ в крови пациентов. У всех пациентов с ИБС зафиксирован повышенный уровень СРБ в плазме крови, в то время как в контрольной группе показатель был ниже определяемого порога. У пациентов со стабильной ИБС концентрация мСРБ составила 2,34 (1,42; 3,27) мкг/л, тогда как наиболее высокий уровень мСРБ отмечен у лиц с острым инфарктом миокарда - 16,76 (3,65; 54,83) мкг/л (р = 0,0002, критерий Краскела - Уоллиса ANOVA). Корреляции уровней мСРБ и показателей нСРБ, высокочувствительного С-реактивного белка и интерлейкина-6 не обнаружено.</p></sec><sec><title>Заключение</title><p>Заключение. Новая тест-система, позволяющая определять уровень мономера С-реактив-ного белка в крови, делает возможным исследование роли мСРБ в патогенезе и течении ИБС. Полученные результаты позволяют утверждать, что мономер С-реактивного белка может играть не меньшую роль, чем его нативная форма, в диагностике и течении кардиологических патологий, а также иных, связанных с воспалительными процессами в организме, заболеваний.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To develop a method for measuring circulating monomeric C-reactive protein and to determine the levels of C-reactive protein isoforms (native pentameric C-reactive protein and monomeric C-reactive protein) in patients with stable coronary artery diseases and acute myocardial infarction.</p></sec><sec><title>Methods</title><p>Methods. Plasma and blood serum samples were collected from 22 patients with stable coronary artery disease (CAD), 14 patients with acute myocardial infarction at days 2-3, and 11 healthy volunteers. The analysis was performed using flow cytofluorometry FACS Cantoll and a set of functional particles Cytometric Bead Array (BD Biosciences, USA). Antibodies for CRP (clones 328 and 372 from ImTek, Russia, and clone 8C8 from Sigma-Aldrich, USA), гСКР-GAH (with antibodies for CRP), native CRP (ImTek, Russia) and recombinant monomeric CRP (received as a gift from Dr. L. Potempa) were used in the analysis.</p></sec><sec><title>Results</title><p>Results. A novel laboratory kit for measuring blood levels of monomeric CRP has been developed. Patients with CAD demonstrated elevated plasma levels of CRP, whereas healthy subjects reported the levels below the lower cut-off. Patients with stable CAD had mCRP concentration of 2.34 (1.42; 3.27) pg/L, whereas patients with acute MI had the highest level of 16.76 (3.65;54.83) pg/L (p = 0.0002, Kruskal-Wallis One Way Annova). There were no any correlations between mCRP levels and nCRP, hs-CRP and IL-6.</p></sec><sec><title>Conclusion</title><p>Conclusion. The novel laboratory kit allows measuring monomeric C-reactive protein and provides novel data on the role of mCRP in the development and progress of CAD. Obtained data suggest that monomeric C-reactive protein can play no less important role than native C-reactive protein in the diagnosis and progress of cardiovascular diseases as well as other diseases associated with the inflammatory process.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Ишемическая болезнь сердца</kwd><kwd>С-реактивный белок</kwd><kwd>Мономерный С-реактивный белок</kwd><kwd>Острый инфаркт миокарда</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Coronary artery disease</kwd><kwd>C-reactive protein</kwd><kwd>mCRP</kwd><kwd>Acute myocardial infarction</kwd></kwd-group><funding-group xml:lang="en"><funding-statement>Monomeric C-reactive protein in coronary artery disease</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">Титов В.Н., Ощепкова Е.В., Дмитриев В.А.
