Material and methods. The study was conducted in the Center of paroxysmal conditions of Vitebsk Regional Clinical Diagnostic Center. The study included 58 women with epilepsy who gave birth in 2018–2020; a prospective analysis was also done using the Russian Register of Pregnancy and Epilepsy (RRPE) data. The study group included 112 women with epilepsy who were taking VA at the time of conception. In 16.1% of cases (n=18 out of 112) VA was discontinued in the first trimester (withdrawal group), in 83.9% of cases (n=94) VA therapy was continued. We analyzed the frequency of epileptic seizures depending on the use of VA during pregnancy for each trimester and for the entire pregnancy as a whole. Results. According to the Vitebsk Regional Clinical Diagnostic Center, 32 out of 58 (55.2%) patients took VA, all of them had generalized tonicclonic seizures in the structure of epileptic seizures. Seven of 32 patients (21.8%) received VA at a dose of &lt;700 mg/day; 10 (31.3%) – 700–1000 mg/day, 15 (46.9%) – 1000–1500 mg/day. VA was canceled in two cases, in one of them a tonic-clonic seizure developed. According to the RRPE data, in 9 out of 65 (13.8%) cases VA was discontinued in the first trimester (withdrawal group), in 55 out of 65 (84.6%) cases the therapy with VA was continued, and in one case - the drug was changed. The number of women with epilepsy taking VA during pregnancy has decreased from 38.9% (275 out of 707) in 2017 to 24.9% (112 out of 450) by January 2023. According to the RRPE, the majority of patients continued VA therapy during gestation if pregnancy occurred while taking this antiepileptic drug. A high fraction of prescribing VA in patients with focal epilepsy was registered – 58.9% (66 out of 112) with continuation of VA therapy during pregnancy in 61.7% of cases. Among patients with generalized form of epilepsy, VA drugs were taken by 36.6% (41 out of 112). The majority of patients (35.1%; 33 of 94) continued to take VA throughout the entire gestation. About half of the patients took VA at a dose of &gt;700 mg/day in the first trimester and throughout gestation. There were no statistically significant differences in the frequency of tonic-clonic and other types of epileptic seizures during pregnancy in patients who canceled VA and continued therapy, according to RRPE. Conclusion. Further prospective and controlled studies with large sample sizes are needed to determine the most effective and safe strategy for VA withdrawal.</p></abstract><trans-abstract xml:lang="ru"><p>Цель исследования – проанализировать особенности течения эпилепсии у женщин после отмены препаратов вальпроевой кислоты (ВК) во время беременности. Материал и методы. Исследование проведено в центре пароксизмальных состояний УЗ «Витебский областной диагностический центр». В исследование включено 58 женщин, страдающих эпилепсией и родивших в 2018–2020 гг., использован также проспективный анализ по данным Российского регистра беременности и эпилепсии (РРБЭ). Оцениваемая группа включала 112 женщин с эпилепсией, которые на момент зачатия принимали ВК. В 16,1% случаев (n=18 из 112) ВК была отменена в I триместре (группа отмены), в 83,9% случаев (n=94) продолжена терапия препаратами ВК. Проведен анализ частоты эпилептических приступов в зависимости от использования ВК на протяжении беременности для каждого триместра и для всей беременности в целом. Результаты. По данным Витебского областного диагностического центра, препараты ВК принимали 32 из 58 (55,2%) пациенток, у всех в структуре эпилептических приступов регистрировались генерализованные судорожные приступы. Семь из 32 пациенток (21,8%) получали ВК в дозе &lt;700 мг/сут; 10 (31,3%) – 700–1000 мг/сут, 15 (46,9%) – 1000–1500 мг/сут. Препараты ВК отменены в двух случаях, из них с развитием тонико-клонических приступов – у одной пациентки. По данным РРБЭ, в 9 из 65 (13,8%) случаев ВК была отменена в I триместре (группа отмены), в 55 из 65 (84,6%) случаев продолжена терапия препаратами ВК, в одном случае проведена замена препарата. Число женщин с эпилепсией, принимающих ВК во время беременности, снизилось с 38,9% (275 из 707) в 2017 г. до 24,9% (112 из 450) к январю 2023 г. По данным РРБЭ, у большинства пациенток продолжена терапия ВК на протяжении гестации, если беременность наступила на фоне приема данного противоэпилептического препарата. Зарегистрирован высокий удельный вес назначения препаратов ВК пациенткам с фокальной эпилепсией – 58,9% (66 из 112) с продолжением терапии ВК на протяжении беременности в 61,7% случаев. Среди пациенток с генерализованной формой эпилепсии препараты ВК принимали 36,6% (41 из 112). Большинство пациенток (35,1%; 33 из 94) продолжили прием ВК на протяжении всей гестации. Около половины пациенток принимали ВК в дозе &gt;700 мг/сут в I триместре и на протяжении всей гестации. Статистически значимых различий в частоте тонико-клонических и других типов эпилептических приступов во время беременности у пациенток, отменивших ВК и продолжавших терапию, по данным РРБЭ не выявлено. Заключение. Необходимы дальнейшие проспективные и контролируемые исследования с большим размером выборки, чтобы выработать наиболее эффективную и безопасную стратегию отмены препаратов ВК.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>вальпроевая кислота</kwd><kwd>беременность</kwd><kwd>эпилепсия</kwd><kwd>противоэпилептические препараты</kwd><kwd>генерализованные тоникоклонические приступы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>valproic acid</kwd><kwd>pregnancy</kwd><kwd>epilepsy</kwd><kwd>antiepileptic drugs</kwd><kwd>generalized tonic-clonic seizures</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Власов ПН.
