Условия нефтедобычи сопряжены с экспозицией эндокринными разрушителями, такими как ароматические углеводороды, эффекты которых ассоциированы, в том числе, с нарушениями иммуно-эндокринной регуляции.</p><p>Цель исследования — изучение особенностей иммунного и генетического статуса работников нефтедобывающего сегмента нефтехимической отрасли с метаболическим синдромом, контаминированных бензолом.</p><p>Обследовано 142 оператора предприятия нефтедобычи с метаболическим синдромом. Группа наблюдения включала работников (n=94), характеризующихся контаминацией биосред бензолом. Группу сравнения составили 48 человек, не контаминированных бензолом. Состояние клеточного иммунитета оценивалось методом проточной цитометрии (CD3+CD8+, CD3+CD95+, CD3+), цитокиновый профиль методом иммуноферментного анализа (IL-6). Полиморфизм генов исследовался методом ПЦР в реальном времени.</p><p>У работников с метаболическим синдромом, контаминированных бензолом, установлены особенности клинического течения метаболического синдрома, сопровождающиеся функциональными и лабораторными признаками атеросклеротического изменения сосудов, а также дисбаланс иммунного профиля, фенотипами которого выступали: увеличение абсолютного и относительного содержания CD3+CD8+-лимфоцитов (в 1,3–1,6 раз соответственно) (р&lt;0,05), CD3+-лимфоцитов (в 1,2–1,3 раза) (р&lt;0,05) относительно группы сравнения, дефицит кластера CD95+ по отношению к референтному интервалу и показателям группы сравнения (в 1,4–1,9 раза; р&lt;0,05), гиперпродукция IL‑6 (в 1,6 раза; р&lt;0,05) относительно значений соответствующих показателей группы рабочих, где контаминация бензолом отсутствовала. Генетический профиль работников (SNP), контаминированных бензолом, позволил установить повышенную в 1,4 раза распространённость С-аллеля гена FADS2 (OR=2,13; 95% CI: 1,05–4,29, p&lt;0,05); в 2,3 раза G-аллеля (OR=3,30; 95% CI: 1,46–7,33, p&lt;0,05) гена TP53.</p><p>Установленные у операторов нефтедобывающего сегмента нефтехимической отрасли с метаболическим синдромом, контаминированных бензолом, особенности иммунного статуса: повышение экспрессии кластеров CD3+ и CD8+-лимфоцитов, цитокина IL-6, снижение CD95+-рецепции лимфоцитов (p&lt;0,05) сопровождались полиморфизмом кандидатных генов FADS2 rs174583 и TP53 rs1042522, ассоциированных с ожирением и апоптозом.</p><sec><title>Этика</title><p>Этика.

Oil production conditions are associated with exposure to endocrine disruptors, such as aromatic hydrocarbons, whose effects are associated, among other things, with disorders of immuno-endocrine regulation.</p><p>The aim of the study was to analyze the features of the immune and genetic status of workers in the oil-producing segment of the petrochemical industry with metabolic syndrome contaminated with benzene.</p><p>142 operators of the oil production enterprise with pathology with metabolic syndrome were examined. The observation group included workers (n=94) characterized by contamination of the biological medium with benzene. The comparison group consisted of 48 people who were not contaminated with benzene. The state of cellular immunity was assessed by flow cytometry (CD3+CD8+, CD3+CD95+, CD3+), cytokine profile by enzyme immunoassay (IL‑6). Gene polymorphism was studied by real-time PCR.</p><p>In workers with metabolic syndrome contaminated with benzene, the features of the clinical course of the metabolic syndrome, accompanied by functional and laboratory signs of atherosclerotic vascular changes, as well as an imbalance of the immune profile, whose phenotypes were: an increase in the absolute and relative content of CD3+CD8+ lymphocytes (1.3–1.6 times, respectively) (p&lt;0.05), CD3+ lymphocytes (1.2–1.3 times) (p&lt;0.05) relative to the comparison group, CD95+ cluster deficiency in relation to the reference interval and the indicators of the comparison group (1.4–1.9 times; p&lt;0.05), IL-6 hyperproduction (1.6 times; p&lt;0.05) relative to the values of the corresponding indicators of the group of workers where benzene contamination was absent. The genetic profile of workers (SNP) contaminated with benzene allowed us to establish a 1.4-fold increased prevalence of the C-allele of the FADS2 gene (OR=2.13; 95% CI: 1.05–4.29, p&lt;0.05); 2.3 times the G-allele (OR=3.30; 95% CI: 1.46–7.33, p&lt;0.05) of the TP53 gene.</p><p>Established in operators of the oil-producing segment of the petrochemical industry with metabolic syndrome contaminated with benzene, features of the immune status: an increase in the expression of CD3+ and CD8+ lymphocyte clusters, IL-6 cytokine, and a decrease in CD95+ lymphocyte reception (p&lt;0.05) were accompanied by polymorphisms of candidate genes FADS2 (rs174583) and TP53 (rs 1042522) associated with obesity and apoptosis.</p><sec><title>Ethics</title><p>Ethics.
