В ходе проведения одноцентрового неконтролируемого исследования были изучены данные 3062 амбулаторных карт юных спортсменов обоих полов (средний возраст составил 15 [14; 16] лет), входящих в состав спортивных сборных команд Российской Федерации и прошедших углубленное медицинское обследование в период с января 2021 по сентябрь 2022 г. Среди них были выделены в отдельную группу спортсмены, результаты анализов крови которых соответствовали общепринятым критериям субклинического гипотиреоза (повышение уровня тиреотропного гормона в диапазоне от 5 до 10 мЕд/л при нормальном уровне свободного тироксина). В ходе динамического наблюдения в течение года спортсменам с субклиническим гипотиреозом проводилось повторное исследование концентрации тиреотропного гормона, свободного тироксина и антител к тиропероксидазе.</p></sec><sec><title>Результаты</title><p>Результаты. В результате проведенного исследования признаки субклинического гипотиреоза были обнаружены у 58 юных спортсменов обоих полов, среди которых 30 (51,7 %) были юношами, а 28 (48,3 %) — девушками. При динамическом наблюдении на фоне сохранения привычной физической и психоэмоциональной нагрузки в течение года спонтанная нормализация уровня тиреотропного гормона отмечалась у 74 % юных спортсменов. При этом нормализация уровня этого гормона у девушек наблюдалась несколько реже по сравнению с юношами (р = 0,272). Ни в одном случае не развился клинически выраженный гипотиреоз.</p></sec><sec><title>Заключение</title><p>Заключение. У большинства юных спортсменов обоих полов с субклиническим гипотиреозом на фоне сохраняющейся физической и психоэмоциональной нагрузки отмечается спонтанная нормализация гормональных показателей. Полученные данные позволяют при условии возможности динамического наблюдения рекомендовать врачам, работающим с юными элитными спортсменами, не назначать таким спортсменам заместительную гормональную терапию и не модифицировать привычный режим жизнедеятельности.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective: to assess the natural course of subclinical hypothyroidism in young athletes.</p></sec><sec><title>Methods</title><p>Methods: In the prospective single-center uncontrolled study, data from 3,062 outpatient records of young athletes (members of the Russian national team) of both sexes (middle age — 15 [14; 16] years) and underwent medical examination in the period from January 2021 to September 2022 were studied. All athletes were divided into 2 groups according to the presence of subclinical hypothyroidism (an increase in the level of thyroid-stimulating hormone from 5 to 10 mUn/l with a normal level of T4 free). During a dynamic follow-up (1 year), athletes with subclinical hypothyroidism underwent a repeated study of the concentration of thyroid-stimulating hormone, free thyroxine and antibodies to thyroperoxidase.</p></sec><sec><title>Results</title><p>Results: Signs of subclinical hyperthyroidism were found in 58 young athletes (30 boys (51.7 %) and 28 (48.3 %) girls). During dynamic observation with continued habitual physical activity, spontaneous normalization of the level of thyroid-stimulating hormone was observed in 74 % of young athletes. At the same time, normalization of thyroid-stimulating hormone in girls was observed less often compared to boys (p = 0,272). In no case did clinically pronounced hypothyroidism develop.</p></sec><sec><title>Conclusion</title><p>Conclusion: The majority of young male and female athletes with subclinical hypothyroidism have spontaneous normalization of hormonal profile against the background of persistent physical and psycho-emotional stress. The data obtained make it possible, subject to the possibility of dynamic observation, to recommend doctors working with young elite athletes not to prescribe hormonal replacement therapy and not to modify the usual lifestyle.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>тиреотропный гормон</kwd><kwd>тиреоидный профиль</kwd><kwd>щитовидная железа</kwd><kwd>элитный спорт</kwd><kwd>субклинический гипотиреоз</kwd><kwd>юные спортсмены</kwd><kwd>спортивная медицина</kwd></kwd-group><kwd-group xml:lang="en"><kwd>thyroid stimulating hormone</kwd><kwd>thyroid profile</kwd><kwd>thyroid gland</kwd><kwd>elite sport</kwd><kwd>subclinical hypothyroidism</kwd><kwd>young athletes</kwd><kwd>sports medicine</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках НИР «Разработка новых подходов к диагностике эндокринных заболеваний и оценке нарушений энергетического баланса несовершеннолетних спортсменов спортивных сборных команд Российской Федерации на основе исследования функционального состояния, гормонального и метаболического статуса, регистрационный номер: 122041800079–0.</funding-statement><funding-statement xml:lang="en">The study was carried out within the framework of scientific research «Development of new approaches to the diagnosis of endocrine diseases and assessment of energy balance disorders of young elite athletes based on the study of the functional state, hormonal and metabolic status».
