These patients have pronounced limitations of motor activity and their life expectancy is between several weeks and several decades. The development and implementation of causal therapy improved the quality of life and increased life expectancy of SMA patients. Nusinersen is one of the first drugs approved for SMA in the Russian Federation. It is an antisense oligonucleotide drug that increases the production of full-length SMN protein.</p><p><bold>Aim. </bold>To confirm the efficacy and safety of Nusinersen in children with type I–III SMA from Moscow region.</p><p><bold>Materials and methods. </bold>A total of 22 patients with type I–III SMA have been receiving Nusinersen since 2020. Treatment outcomes were evaluated using the Children’s Hospital of Philadelphia Infant Test of Neuromuscular Disorders (CHOP INTEND) in children with type I SMA and Hammersmith Functional Motor Scale Expanded (HFMSE) in children with type II–III SMA.</p><p><bold>Results. </bold>All patients completed the stage of loading doses, including 1 patient treated for 5 years (18 injections), 3 patients treated for 3 years (12 injections), 10 patients treated for 2 years (9 injections), 4 patients treated for more than 1 year (6 injections), and 4 patients treated for less than 1 year (5 injections). Patients with type I SMA demonstrated increased scores after one year of therapy. Patients with type I–III SMA also had some improvement and higher HFMSE after loading doses followed by positive dynamics after 2 and 3 years of therapy.</p><p>This article also contains cases that confirm the need of early treatment initiation immediately after the diagnosis.</p><p><bold>Conclusions. </bold>We corroborated the efficacy and safety of Nusinersen in routine clinical practice for children with different types of SMA.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение. </bold>Проксимальная спинальная мышечная атрофия 5q (5qсМА) – тяжелое аутосомно-рецессивное нервномышечное заболевание, характеризующееся прогрессирующими симптомами вялого паралича и мышечной атрофии вследствие дегенерации α-мотонейронов передних рогов спинного мозга, что обусловлено мутациями в гене <italic>SMN1,</italic><italic> </italic>кодирующем белок выживаемости мотонейронов (SMN), с ожидаемой продолжительностью жизни от нескольких недель до нескольких десятков лет, с выраженными ограничениями двигательной активности. Разработка и применение препаратов патогенетической терапии позволили улучшить качество жизни и продлить срок ожидаемой продолжительности жизни у пациентов со СМА. Одним из первых препаратов, зарегистрированных на территории Российской Федерации, является Нусинерсен, представляющий собой препарат антисмысловых олигонуклеотидов, которые увеличивают синтез полноценного белка SMN.</p><p><bold>Цель представленной работы </bold>– подтвердить эффективность и безопасность применения препарата Нусинерсен у детей со СМА I–III типа в Московской области.</p><p><bold>Материалы и методы. </bold>22 пациента детского возраста с диагнозом СМА I–III типа получают лечение препаратом Нусинерсен с 2020 г. по настоящее время. Результаты патогенетической терапии препаратом Нусинерсен оценивались с помощью шкалы CHOP INTEND у детей со СМА I типа и расширенной шкалы оценки моторных функций HFMSE у детей со СМА II–III типа.</p><p><bold>Результаты. </bold>Все пациенты завершили этап нагрузочных доз: 1 пациент получает лечение более 5 лет (проведено 18 введений препарата), 3 года (12 введений) лечатся 3 ребенка, 2 года (9 введений) – 10, более 1 года (6 введений) – 4 пациента, до 1 года (5 введений) – 4 ребенка. У пациентов со СМА I типа отмечено увеличение оценки в баллах через год применения препарата. У пациентов со СМА I–III типа также отмечено прогрессивное увеличение баллов по шкале оценки моторных функций HFMSE после введения нагрузочных доз, с дальнейшей положительной динамикой после 2 и 3 лет патогенетической терапии. При оценке безопасности препарата нежелательных явлений не отмечено.</p><p>В статье также приводятся клинические примеры, подтверждающие необходимость начала патогенетической терапии в более ранние сроки от подтверждения диагноза.</p><p><bold>Выводы. </bold>Подтверждена эффективность и безопасность применения препарата Нусинерсен в условиях реальной клинической практики у детей с различными типами СМА.</p></trans-abstract><kwd-group xml:lang="en"><kwd>spinal muscular atrophy</kwd><kwd>children</kwd><kwd>Nusinersen</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>спинальная мышечная атрофия</kwd><kwd>дети</kwd><kwd>Нусинерсен</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Artemyeva S.B., Kuzenkova L.M., Ilyina E.S. et al.
