Levetiracetam (LEV) is one of the most commonly prescribed antiepileptic drugs (AED). However, there were no studies on its efficacy and safety in terms of the correlation with epileptiform activity index (EAI) performed among the Russian population.</p></sec><sec><title>Aim</title><p>Aim. To evaluate the efficacy and tolerability of LEV monotherapy in patients with newly-diagnosed epilepsy using epileptiform activity index (EAI) assessment.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study included 107 patients (46 (43.0%) male and 61 (57.0%) female) with focal epilepsy (FE) (39.3%; n=42) or idiopathic generalized epilepsy (IGE) (60.7%; n=65). At each visit, video-electroencephalographic (video-EEG) monitoring was performed (baseline and in 1, 3, 6, and 12 months of the therapy). Therapeutic drug monitoring was performed at dose titration in 1 month of the therapy or in case of therapy correction. Treatment efficacy was assessed using the criteria of seizure absence (medically induced remission), seizure rate decrease by &gt;50% (responders), seizure rate decrease by &lt;50% – insufficient efficacy, a composite index of efficacy/tolerability (retention on treatment), and seizure rate increase compared to baseline and/or development of a new type of seizures (aggravation). Adverse events (AE) were assessed using the scale for side effects in AED treatment (SIDAED).</p></sec><sec><title>Results</title><p>Results. Total EAI at baseline was 5.2-fold higher in patients with IGE compared to FE patients (23.4±3.0 and 4.5±0.97, respectively). After 1 month of LEV therapy, EAI decreased to 3.4±1.1 and 1.9±0.4 in patients with IGE and FE, respectively (p&lt;0.01). The decrease continued during the whole follow-up period. Retention on monotherapy was achieved in 82.2% (n=88/107) patients; in 87.6% (n=57/65) patients with IGE and in 73.8% (n=31/42) with FE. The rate of serious AEs during the follow-up period was 8.4% (n=9).</p></sec><sec><title>Conclusions</title><p>Conclusions. LEV is an effective drug of choice for the initial treatment of newly-diagnosed FE and IGE in monotherapy along with a significant decrease in EAI. EAI is an objective measure of LEV treatment efficacy.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Введение</title><p>Введение. Леветирацетам (ЛЕВ) является одним из наиболее современных и часто назначаемых противоэпилептических препаратов (ПЭП), однако исследований по оценке его эффективности и безопасности в корреляции с индексом эпилептиформной активности (ИЭА) в российской популяции не проводилось.</p></sec><sec><title>Цель</title><p>Цель. Оценка эффективности и переносимости монотерапии ЛЕВ у пациентов с впервые выявленной эпилепсией с учетом ИЭА.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В исследование включены 107 пациентов, из них 46 (43,0%) мужчин и 61 (57,0%) женщина. С фокальной эпилепсией (ФЭ) вошли 42 (39,3%) пациента и с идиопатической = генетической генерализованной эпилепсией (ИГЭ) – 65 (60,7%). При каждом посещении (исходное, через 1, 3, 6 и 12 мес. терапии) проводили видео-ЭЭГ-мониторинг. Лекарственный фармакомониторинг применяли при титровании препарата через 1 мес. терапии либо при коррекции терапии. Эффективность терапии оценивали по показателю отсутствия приступов (медикаментозная ремиссия), снижения их частоты более 50% (респондеры), менее 50% – недостаточный эффект, удержание на терапии, а также по увеличению частоты приступов относительно исходной и/или появлению нового типа приступов (аггравация). Нежелательные явления (НЯ) оценивали по шкале «Оценка побочных эффектов при лечении ПЭП» (SIDAED).</p></sec><sec><title>Результаты</title><p>Результаты. Суммарный ИЭА у пациентов с ИГЭ до начала лечения ЛЕВ был в 5,2 раза выше, чем у пациентов с ФЭ (23,4±3,0 и 4,5±0,97 соответственно). Уже через 1 мес. после начала лечения он уменьшился до 3,4±1,1 при ИГЭ и 1,9±0,4 при ФЭ (p&lt;0,01) и продолжал снижаться в течение всего периода наблюдения. Удержание на монотерапии было достигнуто у 88 (82,2%) пациентов, из них у 57 (87,6%) из 65 пациентов с ИГЭ и 31 (73,8%) из 42 пациентов с ФЭ. Суммарно непереносимые НЯ за период наблюдения составили всего 9 (8,4%) случаев.</p></sec><sec><title>Выводы</title><p>Выводы. ЛЕВ является эффективным препаратом выбора для инициального лечения ФЭ и ИГЭ в монотерапии, на фоне приема которого наблюдается значимое снижение ИЭА. ИЭА является объективным показателем эффективности проводимой терапии ЛЕВ.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>идиопатическая эпилепсия</kwd><kwd>генетическая генерализованная эпилепсия</kwd><kwd>фокальная эпилепсия</kwd><kwd>индекс эпилептиформной активности</kwd><kwd>леветирацетам</kwd><kwd>эффективность</kwd><kwd>переносимость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>idiopathic epilepsy</kwd><kwd>genetic generalized epilepsy</kwd><kwd>focal epilepsy</kwd><kwd>epileptiform activity index</kwd><kwd>levetiracetam</kwd><kwd>efficacy</kwd><kwd>tolerability</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">Карлов В.
