Заболевания щитовидной железы (ЩЖ) являются самой распространенной эндокринной патологией. Нейрегулин-4 (NRG4) – адипокин, секретируемый бурой жировой тканью, уровень которого снижен при неалкогольной жировой болезни печени (НАЖБП). Влияние тиреоидного статуса на NRG4 изучено недостаточно.</p></sec><sec><title>Цель</title><p>Цель. Исследовать уровни NRG4 у мужчин с НАЖБП при различном тиреоидном статусе.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В одномоментное исследование включены мужчины 32–49 лет с НАЖБП (n = 70), разделенные по тиреоидному статусу: гипотиреоз (n = 25), субклинический гипертиреоз (n = 20) и нормотиреоз (n = 25). Контрольную группу составили 26 мужчин без патологии ЩЖ и печени. Всем выполнялась точечная эластография сдвиговой волной (pSWE) печени.</p></sec><sec><title>Результаты</title><p>Результаты. Уровень NRG4 в общей группе НАЖБП был достоверно ниже, чем в контроле: 2,1 (1,6; 3,8) нг/мл против 2,95 (2,92; 2,96) нг/мл (p = 0,041). При стратификации выявлена разнонаправленная динамика: снижение NRG4 при нормо- (1,6 нг/мл) и гипотиреозе (2,2 нг/мл), повышение – при субклиническом гипертиреозе (4,0 нг/мл). При гипотиреозе NRG4 коррелировал с жесткостью печени (r = 0,406), при гипертиреозе – с индексом массы тела (r = -0,391).</p></sec><sec><title>Выводы</title><p>Выводы. У пациентов с НАЖБП и гипотиреозом уровень NRG4 ниже, чем при гипертиреозе. Гипотиреоз может усугублять течение НАЖБП за счет подавления защитного адипокина NRG4. Парадоксальное повышение NRG4 при субклиническом гипертиреозе, несмотря на высокие показатели жесткости печени, вероятно, является компенсаторной реакцией на метаболический стресс.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Thyroid diseases are the most common endocrine pathology. Neuregulin-4 (NRG4) is an adipokine secreted by brown adipose tissue, with reduced levels in non-alcoholic fatty liver disease (NAFLD). The influence of thyroid status on NRG4 has been insufficiently studied.</p></sec><sec><title>Aim</title><p>Aim. To investigate NRG4 levels in men with NAFLD and different thyroid status.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. This cross-sectional study included men aged 32–49 years with NAFLD (n = 70), divided by thyroid status: hypothyroidism (n = 25), subclinical hyperthyroidism (n = 20), and normothyroidism (n = 25). The control group consisted of 26 men without thyroid or liver pathology. All participants underwent point shear wave elastography (pSWE) of the liver.</p></sec><sec><title>Results</title><p>Results. The NRG4 level in the overall NAFLD group was significantly lower than in controls: 2.1 (1.6; 3.8) ng/ml vs. 2.95 (2.92; 2.96) ng/ml (p = 0.041). Stratification revealed multidirectional dynamics: decreased NRG4 in normo- (1.6 ng/ml) and hypothyroidism (2.2 ng/ml), and increased levels in subclinical hyperthyroidism (4.0 ng/ml). In hypothyroidism, NRG4 correlated with liver stiffness (r = 0.406); in hyperthyroidism, it correlated with body mass index (r = -0.391).</p></sec><sec><title>Conclusions</title><p>Conclusions. In patients with NAFLD and hypothyroidism, NRG4 levels are lower than in those with hyperthyroidism. Hypothyroidism may exacerbate NAFLD progression by suppressing the protective adipokine NRG4. The paradoxical increase in NRG4 in subclinical hyperthyroidism, despite high liver stiffness, is likely a compensatory response to metabolic stress.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>нейрегулин-4</kwd><kwd>NRG4</kwd><kwd>неалкогольная жировая болезнь печени</kwd><kwd>НАЖБП</kwd><kwd>гипотиреоз</kwd><kwd>субклинический гипертиреоз</kwd><kwd>тиреоидный статус</kwd><kwd>адипокин</kwd><kwd>фиброз печени</kwd><kwd>эластография печени</kwd><kwd>метаболический стресс</kwd></kwd-group><kwd-group xml:lang="en"><kwd>neuregulin-4</kwd><kwd>NRG4</kwd><kwd>non-alcoholic fatty liver disease</kwd><kwd>NAFLD</kwd><kwd>hypothyroidism</kwd><kwd>subclinical hyperthyroidism</kwd><kwd>thyroid status</kwd><kwd>adipokine</kwd><kwd>liver fibrosis</kwd><kwd>liver elastography</kwd><kwd>metabolic stress</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена и профинансирована в рамках плановой научной тематики Военно-медицинской академии имени С.М. Кирова.</funding-statement><funding-statement xml:lang="en">The research was completed and funded within the framework of the scheduled scientific activities of the Military Medical Academy named after S.M.
