Выявление факторов риска клинической конверсии РИС является наиболее актуальной проблемой.</p><p>Цель исследования – оценка частоты регистрации соответствия обновленным критериям РИС 2023 г. среди когорты Новосибирского центра РС, а также определение времени до первого клинического эпизода демиелинизации. Вторичной целью исследования было проведение сравнительного анализа качественных характеристик МРТ в подгруппах пациентов с двухлетней МРТ-активностью и без нее, а также в подгруппах пациентов с конверсией и без конверсии в РС в течение всего периода наблюдения.</p><sec><title>Материал и методы</title><p>Материал и методы. Дизайн исследования был ретроспективным с анализом исходных данных и данных последующего наблюдения. МРТ-активность у пациентов с РИС измерялась ежегодно. В анализ включены 45 пациентов, соответствовавшие критериям РИС 2023 г.</p><p>Результаты и их обсуждение. У 30 из 45 (67 %) пациентов в течение двухлетнего наблюдения обнаружена МРТ-активность в виде появления двух и более новых очагов или одного и более контраст-накапливающего очага. Больные с МРТ-активностью чаще переходили в достоверный РС, чем лица без МРТ-активности (соответственно 53,0 и 6,7 %, p &lt; 0,001). Множественная логистическая регрессия подтвердила повышенный риск развития первого клинического эпизода в группе пациентов с последующей МРТ-активностью (отношение шансов 16,01, 95%-й доверительный интервал 1,52–168,17, p = 0,02). Еще более ранняя диагностика РС на доклинической стадии стала возможной после внедрения обновленных критериев Мак-Дональда (2024 г.). Среди бессимптомных пациентов с РИС соответствие новым критериям РС подтверждено у 71 % (20/28).</p></sec><sec><title>Заключение</title><p>Заключение. Подтвержден ключевой прогностической фактор риска для клинической конверсии РИС в РС – наличие спинальных очагов на исходной МРТ.

RIS is characterized by typical brain or spinal cord lesions indicative of autoimmune inflammatory demyelination.</p><p>The aim of the study was to assess the frequency of RIS according to the updated 2023 criteria among a cohort of the Novosibirsk MS Center and to determine the time to the first clinical episode of demyelination. A secondary objective of the study was to conduct a comparative analysis of MRI quality characteristics in subgroups of patients with and without two-year MRI activity, as well as in subgroups of patients with and without conversion to MS throughout the entire follow-up period.</p><sec><title>Material and methods</title><p>Material and methods. The study design was retrospective, with analysis of baseline and follow-up data. MRI activity in patients with RIS was measured annually. Forty-five patients who met the 2023 RIS criteria were included in the analysis.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. MRI activity, defined as the appearance of two or more new lesions or one or more contrast-enhancing lesions, was detected in 30 of 45 (67 %) patients during two-year follow-up. Patients with MRI activity were more likely to progress to definitive MS than patients without MRI activity (53.0 and 6.7 %, respectively, p &lt; 0.001). Multiple logistic regression confirmed an increased risk of developing a first clinical episode in the group of patients with subsequent MRI activity (odds ratio 16.01, 95% confidence interval 1.52–168.17, p = 0.02). Earlier diagnosis of multiple sclerosis at the preclinical stage became possible after the introduction of the updated McDonald criteria (2024). Among asymptomatic RIS patients, compliance with the new MS criteria was confirmed in 71 % (20/28).</p></sec><sec><title>Conclusions</title><p>Conclusions. The study confirmed the presence of spinal lesions on the initial MRI as a key prognostic risk factor for clinical conversion of RIS to MS. The use of user-friendly biomarkers in real-world clinical practice may increase the potential for personalized clinical intervention and requires further study.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>радиологически изолированный синдром</kwd><kwd>рассеянный склероз</kwd><kwd>факторы МРТ</kwd><kwd>прогноз</kwd></kwd-group><kwd-group xml:lang="en"><kwd>radiologically isolated syndrome</kwd><kwd>multiple sclerosis</kwd><kwd>MRI factors</kwd><kwd>prognosis</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Коробко Д.С., Прокаева А.И., Василькив Л.М., Малкова Н.А., Тулупов А.А. благодарят Российский научный фонд (проект № 23-15-00377) за финансовую поддержку в проведении исследований.
