Сахарный диабет 2 типа (СД2) у мужчин ассоциирован с высокой частотой встречаемости синдрома гипогонадизма. Тестостерон является стероидным гормоном и одним из итоговых метаболитов стероидогенеза, что обуславливает интерес к оценке содержания ключевых стероидных гормонов, их предшественников и метаболитов у мужчин с СД2 в условиях гипо- и эугонадизма.</p></sec><sec><title>ЦЕЛЬ</title><p>ЦЕЛЬ. Оценка особенностей стероидогенеза у мужчин с гипогонадизмом при СД2 с использованием тандемной масс-спектрометрии.</p></sec><sec><title>МЕТОДЫ</title><p>МЕТОДЫ. В сплошное одномоментное скрининговое одноцентровое неинтервенционное исследование были включены мужчины с СД2, обратившиеся за медицинской помощью в ФГБУ «НМИЦ эндокринологии» МЗ РФ в период с октября 2021 по январь 2022 г. Проводились изучение анамнеза, физикальный осмотр с определением индекса массы тела, гликированного гемоглобина, измерение ключевых стероидных гормонов, их предшественников и метаболитов методом тандемной масс-спектрометрии. Сравнение групп проведено с помощью U-критерия Манна–Уитни и χ² с поправкой Йейтса. Корреляционный анализ выполнен методом Спирмена. При определении критерия статистической значимости применялась поправка Бонферрони.  </p></sec><sec><title>РЕЗУЛЬТАТЫ</title><p>РЕЗУЛЬТАТЫ. Пациенты с гипогонадизмом имели статистически значимо более выраженное ожирение по сравнению с мужчинами без гипогонадизма. При сравнительном анализе пациентов в зависимости от наличия гипогонадизма отмечались статистически значимо более низкие показатели предшественников андрогенов 17-гидроксипрегненолона и 17-гидроксипрогестерона у мужчин в группе гипогонадизма. При этом была выявлена положительная статистически значимая корреляция между общим тестостероном и 17-гидроксипрогестероном. Кроме того, 17-гидроксипрогестерон хоть и в меньшей силе, но положительно коррелировал с другими андрогенами — андростендионом (r=0,328; p&lt;0,001) и дегидроэпиандростероном (r=0,183; p=0,004). ЗАКЛЮЧЕНИЕ. В нашем исследовании частота встречаемости гипогонадизма у мужчин с СД2 при определении высокоточным методом тандемной масс-спектрометрии составила 69,5%. Не отмечено влияния заболевания на минералокортикоидное и глюкокортикоидное звенья надпочечникового стероидогенеза. Гипогонадизм ассоциировался со снижением уровня ряда предшественников тестостерона. Наиболее значимым из них являлся 17-гидроксипрогестерон, который может рассматриваться как маркер тестикулярного стероидогенеза. &gt;&lt; 0,001) и дегидроэпиандростероном (r=0,183; p=0,004).</p></sec><sec><title>ЗАКЛЮЧЕНИЕ</title><p>ЗАКЛЮЧЕНИЕ.

Testosterone is a steroid hormone and one of the final metabolites of steroidogenesis, which causes interest in assessing the content of key steroid hormones, their precursors and metabolites in hypogonadal and eugonadal men with T2DM.</p></sec><sec><title>AIMS</title><p>AIMS: Assessment of the features of steroidogenesis in men with hypogonadism in T2DM using tandem mass spectrometry.</p></sec><sec><title>MATERIALS AND METHODS</title><p>MATERIALS AND METHODS: A full-design, cross-sectional, screening, single-center, non-interventional study included men with T2DM, who were he was treated in Endocrinology Research Centre, Moscow. The study was conducted from October 2021 to January 2022. Medical history assessment, physical examination with determination of body mass index (BMI), measurement of key steroid hormones, their precursors and metabolites by isotope dilution liquid chromatography/tandem mass spectrometry, glycated hemoglobin (HbA1c) were performed. The groups were compared using the Mann-Whitney U-test for quantitative indicators and χ² with Yates’ correction for qualitative ones. Correlation analysis was performed by the Spearman correlation method. When determining the criterion of statistical significance, the Bonferroni correction was applied.</p></sec><sec><title>RESULTS</title><p>RESULTS: Patients with hypogonadism had statistically significantly more pronounced obesity compared with eugonadal men. In a comparative analysis of patients, depending on the presence of hypogonadism, there were statistically significantly lower levels of androgen precursors 17-hydroxypregnenolone and 17-hydroxyprogesterone in hypogonadal men. At the same time, a positive statistically significant correlation was found between total testosterone and 17-hydroxyprogesterone. In addition, 17-hydroxyprogesterone, although to a lesser extent, but positively correlated with other androgens - androstenedione (r=0,328; p&lt;0,001) and dehydroepiandrosterone (r=0,183; p=0,004). &gt;&lt; 0,001) and dehydroepiandrosterone (r=0,183; p=0,004).</p></sec><sec><title>CONCLUSIONS</title><p>CONCLUSIONS: In this investigation the prevalence of male hypogonadism in type 2 diabetes, determined by high-precision tandem mass spectrometry, was 69,5%. There was no effect of the disease on the mineralocorticoid and glucocorticoid links of adrenal steroidogenesis. Hypogonadism was associated with decreased levels of a number of testosterone precursors. The most significant of them was 17-hydroxyprogesterone, which can be considered as a marker of testicular steroidogenesis.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>мужчины</kwd><kwd>сахарный диабет</kwd><kwd>масс-спектрометрия</kwd><kwd>стероидогенез</kwd><kwd>тестостерон</kwd><kwd>гипогонадизм</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hypogonadism</kwd><kwd>men</kwd><kwd>testosterone</kwd><kwd>diabetes mellitus</kwd><kwd>mass-spectrometry</kwd><kwd>steroidogenesis</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке «Безен Хелскеа РУС» (Besins Healthcare RUS).</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">Muraleedharan V, Marsh H, Kapoor D, et al.
