Multivoxel <sup>1</sup>H-NMR spectroscopy was used to assess metabolism in the centra semiovale and cingulate gyri.</p> <p><bold><italic>Results.</italic></bold> Based on the multivoxel <sup>1</sup>H-NMR spectroscopy, relative metabolite concentrations in the grey and white matter statistically differed within the study cohort before and after the IVGC treatment. The N-acetylaspartate/choline ratio significantly recovered and the choline/creatine ratio decreased in the anterior cingulate gyri in 27% of patients. The brainstem function score significantly improved in the metabolic response group as compared to the non-metabolic response group.</p> <p><bold><italic>Conclusion. </italic></bold>We should study the potential predictors of RMS activity and the IVGC response to select the RMS relapses when pulse-therapy with IVGCs is definitely indicated. Spectroscopy may reveal RMS pathogenesis variability earlier than conventional MRI.</p></abstract><trans-abstract xml:lang="ru"><p><bold><italic>Введение.</italic></bold> Для пациентов с ремиттирующим типом течения рассеянного склероза (РРС) характерно возникновение обострений, представляющих собой эпизоды неврологического дефицита и требующих уточнения тактики лечения.</p> <p><bold><italic>Целью</italic></bold> данного спектроскопического исследования было выявление обратимых метаболических изменений в веществе головного мозга у пациентов при клиническом обострении РРС и последующее динамическое наблюдение за ними после курса терапии внутривенными глюкокортикостероидами (ВГКС).</p> <p><bold><italic>Материалы и методы.</italic></bold> Пациентам c РРС проведено комплексное неврологическое и нейровизуализационное обследование, включающее оценку по расширенной шкале инвалидизации (EDSS), стандартную магнитно-резонансную томографию (МРТ) головного мозга, протонную магнитно-резонансную спектроскопию (<sup>1</sup>H-МРС) до и после терапии ВГКС. Для получения метаболических показателей области семиовальных центров и поясных извилин применяли мультивоксельную <sup>1</sup>H-MРС.</p> <p><bold><italic>Результаты. </italic></bold>Показатели относительной концентрации метаболитов, полученные при помощи мультивоксельной <sup>1</sup>H-MРС в сером и белом веществе головного мозга, статистически различались внутри исследуемой когорты пациентов до и после терапии ВГКС. У 27% пациентов наблюдалось значительное восстановление соотношения N-ацетиласпартат/холин и снижение соотношения холин/креатин в передних половинах поясных извилин. В подгруппе пациентов с описанным метаболическим ответом на терапию отмечено значительное улучшение неврологических показателей по функциональной шкале стволовых функций по сравнению с группой, не показавшей метаболического ответа.</p> <p><bold><italic>Выводы. </italic></bold>Изучение потенциальных предикторов активности РРС и ответа на терапию ВГКС необходимо для выделения подгруппы обострений РРС, безусловно требующих пульс-терапии глюкокортикостероидными гормонами. Специфическая для РРС неоднородность патогенеза заболевания может проявляться в спектроскопическом профиле пациентов и выявляться раньше, чем на стандартной МРТ.</p></trans-abstract><kwd-group xml:lang="en"><kwd>multiple sclerosis</kwd><kwd>relapse</kwd><kwd>multivoxel 1NMR spectroscopy</kwd><kwd>glucocorticoid treatment</kwd><kwd>predictors</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рассеянный склероз</kwd><kwd>обострение</kwd><kwd>мультивоксельная 1H-МР-спектроскопия</kwd><kwd>терапия глюкокортикостероидными гормонами</kwd><kwd>предикторы</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Федеральное государственное бюджетное учреждение науки Институт мозга человека им.
