Неоптерин (НП) относится к птеридинам, которые представляют собой гетерогенную группу веществ, производных гуанозинтрифосфата, уровень которых повышается при активации макрофагов в ответ на стимуляцию интерферона-ү. Повышение уровней неоптерина отмечается при остром коронарном синдроме и при различных патологических состояниях, сопровождающихся воспалительно-деструктивными изменениями.Цель исследования. Изучить взаимосвязь содержания неоптерина в крови у больных с различными формами ишемической болезни сердца.Материалы и методы. В исследование включены 110 лиц (43 женщин и 67 мужчин) в возрасте от 35 до 80 лет (средний возраст составил 67,9±7,6 лет): 17 больных инфарктом миокарда, 38 больных нестабильной стенокардией, 40 пациентов со стенокардией напряжения, 15 здоровых лиц. Помимо рутинных клинических исследований, у всех определялись уровни НП, sVCAM-1, интерлейкина-6 (ИЛ-6) и С-реактивного белка (СРБ) при помощи высокочувствительных иммуноферментных методов.Результаты. Уровни неоптерина достоверно коррелировали с содержанием СРБ (r = 0,69, р = 0,01), ИЛ-6 (r = 0,36, р = 0,03) и sVCAM-1 (r = 0,42, р = 0,043). Содержание НП, sVCAM-1, ИЛ-6 и СРБ в крови здоровых лиц и у больных стенокардией напряжения достоверно не отличалось. По сравнению с больными стенокардией напряжения у больных нестабильной стенокардией повышены уровни неоптерина – 9,3±4,9 нмоль/л vs 14,9±8,6 (p&lt;0,05) и СРБ – 4,9±3,9 мг/л vs 11,2±10,4 (p&lt;0,05).Заключение. Неоптерин является маркером, участвующим в патогенезе ИБС; уровни его в крови кореллируют с выраженностью системного воспаления и повышены у больных с ОКС.</p></abstract><trans-abstract xml:lang="en"><p>Introduction. Neopterin (NP) concerns to pteridines which represent heterogeneous group of the substances derivative of the guanosinetriphosphate which level raises at activation of macrophages in reply to stimulation of interferon - γ. Increase of neopterin levels is marked in acute coronary syndrome and in the various pathological states, accompanied by infl ammatory-destructive changes.The purpose of research. To study interrelation of the neopterin content in blood in patients with various forms of ishemic heart disease.Materials and methods. 110 persons (43 women and 67 men) are included in research in the age of from 35 till 80 years (middle age has made 67,9±7,6 years): 17 patients with myocardial infarction, 38 patients with unstable angina pectoris, 40 patients with angina of exertion, 15 healthy persons. Besides routine clinical researches, in the all NP levels, sVCAM-1, interleukine-6 (IL-6) and C-reactive protein (CRP) by means of highsensitive immunoferment methods were defi ned.Results. Neopterin levels authentically correlated with CRP content (r=0,42, p=0,01), IL-6 (r=0,36, p=0,03) and sVCAM-1 (r=0,42, p=0,043). Content of NP, sVCAM-1, IL-6 and CRP in blood of healthy persons and in patients with angina of exertion authentically did not differ. In comparison with the patients with angina of exertion, in patients with unstable angina pectoris neopterin levels are higher - 9,3±4,9 nmol/l vs 14,9±8,6 (p&lt;0,05) and CRP - 4,9±3,9 mg/l vs 11,2±10,4 (p &lt;0,05). The conclusion. Neopterin is a marker participating in IHD pathogenesis; its levels in blood correlate with expressiveness of a system infl ammation and are higher in patients with acute coronary syndrome (ACS).</p></trans-abstract><kwd-group xml:lang="ru"><kwd>острый коронарный синдром</kwd><kwd>неоптерин</kwd><kwd>воспаление</kwd></kwd-group><kwd-group xml:lang="en"><kwd>acute coronary syndrome</kwd><kwd>neopterin</kwd><kwd>infl ammation</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">Насонов Е.Л.
