The study included 90 participants (mean age 36.30±12.83 years, the majority (58.89%) were males) divided into three groups: 30 non-epileptic people (control Group 1), 30 newly diagnosed epileptic patients (Group 2), and 30 patients with long-term tonic-clonic seizures epilepsy (Group 3). In Group 3, patients received sodium valproate therapy. All subjects underwent clinical and neurological examinations. Differences in plasma levels of homocysteine, folic acid and vitamin B12 in three groups were investigated after 6 months of follow-up.</p></sec><sec><title>Results</title><p>Results. Homocysteine level in Groups 2 and 3 was increased; for Group 2 it was significantly higher than for Groups 3 and 1 (p=0.001). Plasma folate level in Groups 2 and 3 was decreased; for Group 3 it was significantly higher than for Group 2 and lower than for Group 1 (p=0.001). Vitamin B12 level in Groups 2 and 3 was decreased, but the difference was not significant (p=0.090). In Groups 1 and 2, a significant correlation was observed between the indicators.</p></sec><sec><title>Conclusion</title><p>Conclusion. Sodium valproate аdministration might disrupt the homeostatic level of homocysteine, folate and vitamin B12 and cause irregularity of their plasma contents in epileptic patients with long-standing tonic-clonic seizures.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Цель</title><p>Цель: изучить влияние вальпроата натрия на концентрации гомоцистеина, фолата и витамина B12 в плазме крови у больных с длительно присутствующей эпилепсией с тонико-клоническими приступами в сравнении с пациентами с впервые диагностированной эпилепсией и контрольной группой.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В исследование включены 90 участников (средний возраст 36,30±12,83 года, большинство (58,89%) составляли мужчины), которые были разделены на три группы: 30 человек, не страдающих эпилепсией (контрольная 1-я группа), 30 больных с впервые выявленной эпилепсией (2-я группа) и 30 пациентов с длительно присутствующей эпилепсией с тонико-клоническими приступами (3-я группа). В 3-й группе больные получали вальпроат натрия. Все участники исследования прошли клиническое и неврологическое обследование. Различия в уровнях гомоцистеина, фолиевой кислоты, витамина B12 в плазме крови в трех группах исследовали через 6 мес наблюдения.</p></sec><sec><title>Результаты</title><p>Результаты. Зарегистрирован повышенный уровень гомоцистеина во 2-й и 3-й группах; во 2-й группе он был достоверно выше, чем в 3-й и 1-й группах (р=0,001). Уровень фолатов в плазме во 2-й и 3-й группах оказался снижен; в 3-й группе он был достоверно выше, чем во 2-й группе, и ниже, чем в 1-й группе (р=0,001). Снижение уровня витамина В12 во 2-й и 3-й группах было недостоверно (р=0,090). В 1-й и 2-й группах наблюдалась значимая корреляция между показателями.</p></sec><sec><title>Заключение</title><p>Заключение. Введение вальпроата натрия может нарушить гомеостатические уровни гомоцистеина, фолата и витамина В12 и вызвать их колебания в сыворотке крови у больных с длительно присутствующей эпилепсией с тонико-клоническими приступами.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Впервые диагностированная эпилепсия</kwd><kwd>длительно присутствующая эпилепсия</kwd><kwd>вальпроат натрия</kwd><kwd>фолат</kwd><kwd>гомоцистеин</kwd><kwd>витамин B12</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Newly diagnosed epileptic seizures</kwd><kwd>long-standing epilepsy</kwd><kwd>sodium valproate</kwd><kwd>folate</kwd><kwd>homocysteine</kwd><kwd>vitamin B12</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Проект профинансирован Бабольским университетом медицинских наук в качестве магистерской диссертации A.
