Примерно 85 % пациентов с РС имеют ремиттирующее течение, которое в половине случаев в течение 15–20 лет переходит в неуклонное прогрессирование с сохранением активности или без нее в виде обострений или новых активных очагов. Диагностика вторично-прогрессирующего РС (ВПРС) затруднена, и диагноз ВПРС ставится ретроспективно. Поэтому мы в нашей статье рассматриваем варианты надежных и объективных биомаркеров, которые служат предикторами конверсии и являются источниками для перспективного прогнозирования заболевания.</p></abstract><trans-abstract xml:lang="en"><p>Currently, the multiple sclerosis (MS) is the second most common cause of disability in young people after injury [<xref ref-type="bibr" rid="cit1">1</xref>]. Approximately 85 % of patients with MS have a relapsing course, which in a half of cases occurs within 15–20 years, culminating in steady progression with or without activity remaining in the form of an exacerbation or new active foci. Diagnosis of secondary progressive MS (SPMS) is difficult and the diagnosis of SPMS is made retrospectively. Therefore, in our article, we considered options for reliable and objective biomarkers that are natural predictors of conversion and are sources for long-term prediction of diseases.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ремиттирующий рассеянный склероз</kwd><kwd>вторично-прогрессирующий рассеянный склероз</kwd><kwd>предикторы</kwd><kwd>расширенная шкала инвалидности</kwd><kwd>Функциональный комплекс рассеянного склероза</kwd><kwd>биомаркер</kwd></kwd-group><kwd-group xml:lang="en"><kwd>remitting multiple sclerosis</kwd><kwd>secondary progressive multiple sclerosis</kwd><kwd>predictors</kwd><kwd>expanded disability status scale</kwd><kwd>multiple sclerosis functional complex</kwd><kwd>biomarker</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">Sawcer S, Franklin RJ, Ban M.
