Обсуждается участие растворимого рецептора лептина (РРЛ) в формировании гиперлептинемии и лептинорезистентности у больных ишемической болезнью сердца (ИБС) в сочетании с ожирением. Цель – изучение роли РРЛ в патогенезе ИБС. Материалы и методы. Проведено когортное исследование 744 пациентов: 465 больных ИБС (56 лет, Q1=44; Q3=62), 270 обследованных без ИБС (52 года, Q1=44; Q3=56). Методы исследования: ЭХО-КГ, КТ сердца, КАГ. В сыворотке крови оценивали липидный спектр, глюкозу, креатинин, мочевую кислоту, С-реактивный белок высокочувствительным методом (ВЧ-СРБ). Методом иммуноферментного анализа в сыворотке крови определяли концентрации РРЛ, лептина (ЛН), адипонектина (общего и высокомолекулярного), белка-связывающего жирные кислоты-4 (FABP-4), фактора некроза опухолей-альфа (ФНО-α), интерлейкина-6 (ИЛ-6), инсулина. Результаты. Уровень РРЛ в сыворотке крови у мужчин и женщин, больных ИБС, ниже, чем у мужчин без ИБС (р&lt;0,001). У больных ИБС наличие ожирения ассоциировалась с низким уровнем РРЛ в сыворотке крови и высоким индексом свободного ЛН. При концентрации РРЛ в сыворотке крови &lt;7,5 нг/мл у мужчин, больных ИБС, встречаемость ожирения была выше одновременно с признаками висцерального ожирения сердца, наличием атеросклеротических бляшек (АТБ) в общих сонных артериях, высокими уровнями глюкозы, инсулина, ИЛ-6, ЛН сыворотки крови, соотношения ЛН/адипонектин сыворотки крови и высоким индексом НОМА-IR. У женщин, больных ИБС, с уровнем РРЛ &lt;10,2нг/мл чаще выявляли сахарный диабет, висцеральное ожирение, высокие уровни ВЧ-СРБ, ФНО-α, FABP-4, инсулина сыворотки крови, индекса НОМА-IR. У мужчин и женщин, больных ИБС, различий по концентрации РРЛ в зависимости от степени коронарного атеросклероза не выявлено. Заключение. Повышение индекса свободного ЛН отражает нарушение связей в системе «лептин – рецептор» и отражает механизмы компенсации для преодоления резистентности периферических тканей к лептину, что подтверждается заметной отрицательной связью между уровнями РРЛ и лептина в сыворотке крови у мужчин с ИБС. Низкая концентрация РРЛ у больных ИБС ассоциируется с ожирением, проатерогенными и провоспалительными маркерами сердечно-сосудистых заболеваний.</p></abstract><trans-abstract xml:lang="en"><p>Introduction. The participation of soluble leptin receptor (SLR) in the formation of hyperleptinemia and leptin resistance in patients with coronary artery disease (CAD) in combination with obesity is discussed. Aim. Study of the role of SLR in the pathogenesis of ischemic heart disease. Materials and methods. A cohort study of 744 patients was performed: 465 patients with CAD (56 years old, Q1=44; Q3=62), 270 patients without CAD (52 years old, Q1=44; Q3=56). Methods: EchoCG, heart computed tomography, coronary angiography. In the blood serum, the lipids, glucose, creatinine, uric acid, and c-reactive protein were assessed using a highly sensitive method (HF-CRP). Concentrations of SLR, leptin (LN), adiponectin (total and high molecular weight), fatty acid binding protein-4 (FABP-4) tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), serum insulin were determined by enzyme immunoassay. Results. The level of SLR in blood serum in men and women with CAD is lower than in men without CAD (p &lt;0.001). In CAD patients, obesity was associated with a low SLR level in the blood serum and a high free LN index. At a serum SLR concentration of &lt;7.5ng/ml in men with CAD, the incidence of obesity was higher simultaneously with signs of visceral obesity of the heart, the presence of atherosclerotic plaques in the common carotid arteries, high glycaemic levels, insulin, IL-6, and LN in serum, serum LN/adiponectin ratio and a high HOMA-IR index. Diabetes mellitus, visceral obesity, high levels of hs-CRP, TNF-α, FABP-4, serum insulin, and HOMA-IR index were more often detected in women with coronary artery disease with SLR &lt;10.2 ng/ml. In men and women with CAD, there were no differences in SLR concentration depending on the extent of coronary atherosclerosis. Conclusion. An increase in the free LN index indicates the disruption of connections in the leptin-receptor system and reflects the mechanisms of compensation for overcoming the resistance of peripheral tissues to leptin, which is confirmed by a noticeable negative relationship between the levels of SLR and leptin in the serum of men with coronary artery disease. A low concentration of SLR in patients with CAD is associated with obesity, pro-atherogenic and pro-inflammatory markers of cardiovascular diseases.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ишемическая болезнь сердца</kwd><kwd>растворимый рецептор лептина</kwd><kwd>лептин</kwd><kwd>атеросклероз</kwd><kwd>воспаление</kwd><kwd>лептинорезистентность</kwd><kwd>инсулинорезистентность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ischemic heart disease</kwd><kwd>soluble leptin receptor</kwd><kwd>leptin</kwd><kwd>atherosclerosis</kwd><kwd>inflammation</kwd><kwd>leptin resistance</kwd><kwd>insulin  resistance</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Автор выражает признательность за оказанную  помощь в осуществлении работы сотрудникам  ФГБОУ ВО «ПСПбГМУ им.
