Their long-term use increases the risk of a decrease in bone mineral density (BMD) and low-energy fractures. Despite the growing number of studies of drug-induced osteoporosis, the effect of anticonvulsants on bone microarchitecture remains poorly studied.</p> <p><bold>AIM:</bold> To study the effect of treatment duration with different generations of anticonvulsants on bone mineral density and fracture risk.</p> <p><bold>METHODS: </bold>We examined 100 adult patients with epilepsy who had been on anticonvulsants for more than 12 months and 58 healthy subjects who had never taken anticonvulsants. All the participants underwent a general clinical and neuropsychological assessment, as well as bone densitometry using quantitative computed tomography in three regions of interest (lumbar vertebrae L1, L2 and femoral neck).</p> <p><bold>RESULTS:</bold> BMD reductions were observed in 47 patients (47%) taking anticonvulsants and 29 (50%) subjects in the control group. The mean duration of anticonvulsant therapy was 8.7 years (SD=8.05) in patients with normal BMD, 10.7 years (SD=7.07) in patients with osteopenia, and 9.5 years (SD=5.24) in patients with osteoporosis. Age was found to significantly affect BMD, while the duration of anticonvulsant therapy affected it to a lesser extent. Patients taking first-generation anticonvulsants had lower BMD (<italic>p</italic>=0.018). ROC analysis confirmed the existence of a relationship between the duration of anticonvulsant therapy and the risk of fractures (<italic>p</italic>&lt;0.001). The “duration of anticonvulsant therapy” threshold at the cut-off point corresponding to the highest Youden index value was 10 years.</p> <p><bold>CONCLUSION:</bold> Long-term treatment with conventional anticonvulsants adversely affects BMD and can lead to pathological bone resorption, increasing the risk of fractures in patients. New-generation anticonvulsants did not show any significant negative impact on BMD. The results of this study indicate the need for further research to better understand the effects of anticonvulsants on bone tissue.</p></abstract><trans-abstract xml:lang="ru"><p><bold>ВВЕДЕНИЕ: </bold>Антиконвульсанты широко применяются для лечения пациентов с неврологическими заболеваниями и психическими расстройствами. Их длительный приём повышает риск снижения минеральной плотности костной ткани (МПКТ) и низкоэнергетических переломов. Несмотря на рост исследований лекарственно-индуцированного остеопороза, влияние антиконвульсантов на микроархитектонику костной ткани изучено недостаточно.</p> <p><bold>ЦЕЛЬ: </bold>Изучить влияние длительности приема антиконвульсантов различных поколений на МПКТ и риск развития переломов.</p> <p><bold>МЕТОДЫ: </bold>Обследовали 100 взрослых пациентов с эпилепсией, принимающих антиконвульсанты более 12 месяцев, и 58 здоровых участников, которые никогда не принимали антиконвульсанты. Все участники прошли общеклиническое, психиатрическое и неврологическое обследование, а также денситометрическое исследование с помощью количественной компьютерной томографии в трех точках (поясничные позвонки L1, L2 и шейка бедра).</p> <p><bold>РЕЗУЛЬТАТЫ: </bold>У 47 (47%) пациентов, принимающих антиконвульсанты, выявили снижение МПКТ, в контрольной группе — у 29 (50%). Средняя длительность приёма антиконвульсантов у пациентов с нормальной МПКТ составила 8,7 года (SD=8,05), с остеопенией — 10,7 года (SD=7,07), с остеопорозом — 9,5 года (SD=5,24). Установлено, что возраст значительно влияет на показатели МПКТ, а длительность приёма антиконвульсантов — в меньшей степени. Пациенты, принимающие антиконвульсанты первого поколения, имели более низкие показатели МПКТ (<italic>p</italic>=0,018). ROC-анализ подтвердил связь между длительностью приёма антиконвульсантов и риском переломов (<italic>p</italic>&lt;0,001). Пороговое значение показателя «длительность приема антиконвульсантов» в точке cut-off, которой соответствовало наивысшее значение индекса Юдена, — 10 лет.</p> <p><bold>ЗАКЛЮЧЕНИЕ: </bold>Длительная терапия традиционными антиконвульсантами негативно влияет на МПКТ и может приводить к патологической остеорезорбции, увеличивая риск переломов у пациентов. Антиконвульсанты нового поколения не показали выраженного негативного воздействия на МПКТ. Результаты исследования указывают на необходимость дальнейших исследований для более точного понимания влияния антиконвульсантов на костную ткань.</p></trans-abstract><kwd-group xml:lang="en"><kwd>epilepsy</kwd><kwd>bone mineral density</kwd><kwd>osteoporosis</kwd><kwd>osteopenia</kwd><kwd>densitometry</kwd><kwd>anticonvulsants</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>эпилепсия</kwd><kwd>минеральная плотность костной ткани</kwd><kwd>остеопороз</kwd><kwd>остеопения</kwd><kwd>денситометрия</kwd><kwd>антиконвульсанты</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="en">Russian Science Foundation</institution></institution-wrap><institution-wrap><institution xml:lang="ru">Российский научный фонд</institution></institution-wrap></funding-source><award-id>23-25-00104</award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Kindras MN, Ermakova AE.
