Помимо таких факторов риска, как избыточная масса тела, возраст старше 65 лет, сердечно-сосудистые заболевания, сахарный диабет и бронхиальная астма, необходимо также акцентировать внимание и на других хронических заболеваниях с учетом возможной иммуносупрессивной терапии. В данной публикации представлены два клинических случая перенесенной инфекции COVID-19 больными рассеянным склерозом, находящихся на терапии препаратом окрелизумаб. В ходе заболевания у обеих пациенток развился цитокиновый шторм и проводилась терапия блокаторами ИЛ-6. Оба случая завершились выздоровлением с последующим возвращением к анти-В-клеточной терапии. С учетом механизма действия препарата окрелизумаб имеются более высокие риски инфекционных осложнений, в т. ч. и при COVID-19, однако летальность не превышает среднего уровня по популяции. Опубликованная к настоящему времени информация, возможно, послужит поводом для рассмотрения вопроса о применении расширенного интервала дозирования с целью минимизировать возможные риски инфицирования COVID-19, которые, вероятно, наиболее высоки именно в первые месяцы после инфузии.</p></abstract><trans-abstract xml:lang="en"><p>The COVID-19 pandemic was announced in 2020, and many professional medical societies had to review their algorithms for the management of high-risk patients. In addition to risk factors such as overweight, age over 65 years, cardiovascular disease, diabetes mellitus, and bronchial asthma, other chronic diseases should also be emphasized, taking into account possible immunosuppressive therapy. This publication presents two clinical cases of COVID-19 infection in patients with multiple sclerosis treated with ocrelizumab. During the course of the disease, both patients developed a cytokine storm and were treated with IL-6 blockers. Both cases ended with recovery and a subsequent return to anti-B-cell therapy. Given the mechanism of action of ocrelizumab, there are higher risks of infectious complications, including with COVID-19, but mortality is not higher than the population average. The information published to date may serve as a reason to consider the use of extended dosing intervals to minimize the possible risks of COVID-19 infection, which are probably highest in the first months after infusion.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рассеянный склероз</kwd><kwd>COVID-19</kwd><kwd>пандемия</kwd><kwd>цитокиновый шторм</kwd><kwd>окрелизумаб</kwd></kwd-group><kwd-group xml:lang="en"><kwd>multiple sclerosis</kwd><kwd>COVID-19</kwd><kwd>pandemic</kwd><kwd>cytokine storm</kwd><kwd>ocrelizumab</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">Zhou F., Yu T., Du R., Fan G., Liu Y, Liu Z. et al.
