Given the available evidence base, understanding of the pathogenesis underlying secondary progression, and accumulated clinical experience, it is important not only to make a timely diagnosis and prescribe adequate therapy, but also to monitor for continued progression in order to revise treatment with the aim of preventing patient disability. This publication describes a clinical case of a patient with secondary progressive multiple sclerosis (SPMS) who received therapy with an anti-CD20 monoclonal antibody infusion. The patient showed complete suppression of activity and no exacerbations, but despite this, there was a gradual progression on the EDSS scale from 4.5 to 6.0 points over 3 years of therapy. In this regard, the patient was transferred to therapy with siponimod, against which a decrease to 5.5 points was noted within a few months. At the time of publication, this indicator has remained stable for 3 years, indicating that the main goal of therapy for SPMS – preventing secondary progression – has been achieved.</p><p>Therefore, when treating patients with SPMS and ongoing secondary progression, even with complete suppression of activity and no exacerbations, including against the background of infusion therapy with anti-CD20 monoclonal antibody drugs, it is necessary to consider switching to siponimod therapy.</p></abstract><trans-abstract xml:lang="ru"><p>Патогенез рассеянного склероза многогранен и не до конца изучен, но к настоящему времени уже понятно, что каждому пациенту свойственно свое соотношение степени выраженности воспаления и нейродегенерации. С учетом имеющейся доказательной базы, понимания патогенеза, лежащего в основе вторичного прогрессирования, и накопленного клинического опыта важно не только своевременно поставить диагноз и назначить адекватную терапию, но и не пропустить продолжение прогрессирования для пересмотра лечения с целью предотвращения инвалидизации пациентов. В данной публикации описан клинический случай пациента с вторично-прогрессирующим рассеянным склерозом (ВПРС), получавшего терапию инфузионным препаратом анти-CD20-моноклональных антител. У пациента наблюдались полное подавление активности и отсутствие обострений, однако, несмотря на это, отмечалось постепенное прогрессирование по шкале EDSS с 4,5 до 6,0 балла за 3 года терапии. В связи с этим пациент был переведен на терапию препаратом сипонимод, на фоне которой отмечено снижение прогрессирования до 5,5 балла в течение нескольких месяцев. На момент публикации этот показатель остается стабильным на протяжении 3 лет, что свидетельствует о достижении основной цели терапии при ВПРС – предотвращения вторичного прогрессирования.</p><p>Таким образом, при ведении пациентов с ВПРС и продолжающимся вторичным прогрессированием, даже при полном подавлении активности и отсутствии обострений, в том числе на фоне инфузионной терапии препаратами анти-CD20-моноклональных антител, необходимо рассмотреть перевод на терапию препаратом сипонимод.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рассеянный склероз</kwd><kwd>сипонимод</kwd><kwd>нейродегенерация</kwd><kwd>нейрофиламенты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>multiple sclerosis</kwd><kwd>siponimod</kwd><kwd>neurodegeneration</kwd><kwd>neurofilaments</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">Михайленко АА, Бисага ГН, Гусева НА, Скулябин ДИ.
