Ожирение и сахарный диабет 2 типа (СД2) являются широко распространенными метаболическими нарушениями. Окситоцин, известный нейропептид, в последние годы рассматривается как потенциальный регулятор энергетического обмена, аппетита и чувствительности к инсулину.</p></sec><sec><title>ЦЕЛЬ</title><p>ЦЕЛЬ. Изучить взаимосвязь между уровнями окситоцина в крови и метаболическими показателями у пациентов с ожирением и недавно диагностированным СД2.</p></sec><sec><title>МАТЕРИАЛЫ И МЕТОДЫ</title><p>МАТЕРИАЛЫ И МЕТОДЫ. В исследование включено 96 человек, разделенных на группы с нормальной толерантностью к глюкозе (НТГ, n=48) и с впервые выявленным СД2 (n=48). Каждая группа подразделялась на подгруппы с нормальным весом и ожирением. Измерялись антропометрические параметры, показатели углеводного и липидного обменов, инсулин, гликированный гемоглобин (HbA1c), а также высокочувствительный С-реактивный белок. Инсулинорезистентность и функцию β-клеток оценивали с помощью модели HOMA.</p></sec><sec><title>РЕЗУЛЬТАТЫ</title><p>РЕЗУЛЬТАТЫ. Уровни окситоцина были значительно ниже у пациентов с СД2 по сравнению с пацентами с НТГ (p&lt;0,01), а также у лиц с ожирением по сравнению с имеющими нормальную массу тела (p&lt;0,01). Низкий окситоцин отрицательно коррелировал с ИМТ, окружностью талии, HbA1c, глюкозой, инсулином, липидами и вч-СРБ, но положительно с функцией β-клеток. Множественная регрессия показала, что уровень глюкозы через 2 часа, ИМТ и общий холестерин являются независимыми предикторами снижения окситоцина.</p></sec><sec><title>ЗАКЛЮЧЕНИЕ</title><p>ЗАКЛЮЧЕНИЕ. У пациентов с ожирением и ранним СД2 выявлено значительное снижение циркулирующего окситоцина, ассоциированное с неблагоприятными метаболическими профилями. Эти результаты подчеркивают возможную роль окситоцина как биомаркера ранней метаболической дерегуляции и открывают перспективы для разработки новых терапевтических подходов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>BACKGROUND</title><p>BACKGROUND. Obesity and type 2 diabetes (T2D) are common metabolic disorders. Oxytocin, a hypothalamic neuropeptide, has recently been recognized as a potential regulator of energy balance, appetite, and insulin sensitivity.</p></sec><sec><title>OBJECTIVE</title><p>OBJECTIVE. To investigate the relationship between circulating oxytocin levels and metabolic parameters in individuals with obesity and newly diagnosed T2D.</p></sec><sec><title>MATERIALS AND METHODS</title><p>MATERIALS AND METHODS. A total of 96 participants were enrolled, including 48 with normal glucose tolerance (NGT) and 48 with newly diagnosed T2D, each subdivided into normal-weight and obese groups. Anthropometric indices, glucose and lipid parameters, insulin, HbA1c, and high-sensitivity C-reactive protein were measured. Insulin resistance and β-cell function were assessed using the HOMA model.</p></sec><sec><title>RESULTS</title><p>RESULTS. Circulating oxytocin levels were significantly lower in patients with T2D compared to NGT (p &lt; 0.01), and in obese compared to normal-weight participants (p &lt; 0.01). Low oxytocin was negatively correlated with BMI, waist circumference, HbA1c, glucose, insulin, lipids, and hs-CRP, but positively with β-cell function. Multiple regression analysis identified 2-hour glucose, BMI, and total cholesterol as independent predictors of oxytocin levels.</p></sec><sec><title>CONCLUSION</title><p>CONCLUSION. Patients with obesity and newly diagnosed T2D exhibit markedly reduced circulating oxytocin levels, associated with adverse metabolic profiles. These findings highlight oxytocin as a potential biomarker of early metabolic dysregulation and suggest new therapeutic perspectives.</p></sec></trans-abstract><kwd-group
