Information on the characteristics of Russian patients with SMA 5q and the therapy administered in real clinical practice is currently limited.</p><p><bold>Aim.</bold> To describe a cohort of Russian patients with a confirmed diagnosis of SMA 5q and to evaluate patient routing data in real clinical practice settings in Russia.</p><p><bold>Materials and methods</bold>. The present study was a descriptive non-interventional retrospective cohort study in patients diagnosed with SMA 5q who were enrolled in the Russian patient registry between January 1, 2020 and March 31, 2023. Study participants who met the inclusion criteria were automatically identified in the integrated database of the SMA 5q patient registry. Data were uploaded into validated electronic charts, verified and analyzed using descriptive statistics methods. Results. As of March 31, 2023, the Russian SMA registry contained information on 1408 patients from all federal districts and obtained epidemiological, sociodemographic and clinical characteristics of patients, as well as routes to diagnosis and treatment regimens for patients. The median time from disease onset to confirmed diagnosis was 3 months in patients with SMA type 1, 9 months in patients with SMA type 2, 20 months in patients with SMA type 3 and 68 months in patients with SMA type 4. The median time from confirmed diagnosis to the start of disease-modifying therapy was 0.5 months in SMA patients identified by neonatal screening, 21 months in patients with SMA type 1, 59 months in patients with SMA type 2, 47 months in patients with SMA type 3 and 87 months in patients with SMA type 4.</p><p><bold>Conclusion</bold>. This retrospective analysis was carried out in order to identify recent approaches to the diagnosis and treatment of SMA used in real-world clinical practice in Russia. The identified parameters (duration from the disease onset to confirmed diagnosis, duration from the confirmed diagnosis to disease-modifying therapy initiation) indicate that more widespread use of newborn screening and more rapid treatment initiation are unmet needs for SMA patients in Russia.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение.</bold> Существующие регистры пациентов со спинальной мышечной атрофией (СМА) 5q служат ценным источником информации о выявленных больных. Информация о характеристиках российских пациентов со СМА 5q и проводимой терапии в условиях реальной клинической практики в настоящее время ограниченна.</p><p><bold>Цель исследования</bold> – описание когорты российских пациентов с подтвержденным диагнозом СМА 5q, а также оценка данных по маршрутизации пациентов в условиях реальной клинической практики в России.</p><p><bold>Материалы и методы.</bold> Настоящее исследование представляло собой описательное неинтервенционное ретроспективное когортное исследование у пациентов с диагнозом СМА 5q, внесенных в российский регистр пациентов в период с 1 января 2020 г. по 31 марта 2023 г. Участников исследования, соответствовавших критериям включения, автоматически идентифицировали в интегрированной базе данных регистра пациентов со СМА 5q. Данные загружали в утвержденные электронные карты, проверяли и анализировали с использованием методов описательной статистики. Результаты. По состоянию на 31 марта 2023 г. в российском регистре пациентов со СМА 5q содержалась информация о 1408 пациентах. Были описаны и проанализированы эпидемиологические, социально-демографические и клинические характеристики и маршрутизация пациентов со СМА 5q и применяемые схемы лечения. Медиана времени от дебюта болезни до подтверждения диагноза составила 3 мес у пациентов со СМА 1-го типа, 9 мес у пациентов со СМА 2-го типа, 20 мес у пациентов со СМА 3-го типа и 68 мес у пациентов со СМА 4-го типа. Медиана времени с момента подтверждения диагноза до начала патогенетической терапии составила 0,5 мес у пациентов со СМА, выявленных при неонатальном скрининге, 21 мес у пациентов со СМА 1-го типа, 59 мес у пациентов со СМА 2-го типа, 47 мес у пациентов со СМА 3-го типа и 87 мес у пациентов со СМА 4-го типа.</p><p><bold>Выводы.</bold> Данный ретроспективный анализ проведен с целью оценки подходов к диагностике и лечению СМА 5q, применяемых в условиях реальной клинической практики в России. Выявленные показатели (продолжительность периода от дебюта болезни до подтверждения диагноза, продолжительность периода от подтверждения диагноза до начала патогенетической терапии) свидетельствуют о том, что более широкое внедрение неонатального скрининга и оптимизация сроков начала лечения являются неудовлетворенными потребностями пациентов со СМА 5q в России.</p></trans-abstract><kwd-group xml:lang="en"><kwd>spinal muscular atrophy 5q</kwd><kwd>demographic characteristics</kwd><kwd>detection rate</kwd><kwd>prevalence</kwd><kwd>genetic testing</kwd><kwd>diagnostic delay</kwd><kwd>neonatal screening</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>спинальная мышечная атрофия 5q</kwd><kwd>демографические характеристики</kwd><kwd>частота выявления</kwd><kwd>распространенность</kwd><kwd>генетическое тестирование</kwd><kwd>задержка диагностики</kwd><kwd>неонатальный скрининг</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The study was supported by Novartis Pharma LLC (Russia)</funding-statement><funding-statement xml:lang="ru">Исследование выполнено при поддержке ООО «Новартис Фарма» (Россия)</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Kolb S.J., Kissel J.T.
