В исследование были включены 24 пациента с аффективными расстройствами, из них у 13 диагностирован текущий депрессивный эпизод в рамках рекуррентного депрессивного расстройства, у 11 человек – биполярное аффективное расстройство. Всем пациентам проводилось бесконтрастное магнитно-резонансное исследование головного мозга с использованием стандартного протокола сканирования и МР-протокола быстрого картирования МПФ. Сравнение показателей МПФ контрольной и экспериментальной группы проводилось с помощью U-критерия Манна–Уитни. Для оценки прогностической ценности изученных параметров был использован ROC-анализ.</p></sec><sec><title>Результаты</title><p>Результаты. Усредненные показатели МПФ всех выделенных регионов интереса группы контроля и пациентов с аффективными расстройствами (АР) значимо различались (р &lt; 0,0001). При попарном сравнении каждой выделенной области у больных АР наблюдалось достоверное снижение МПФ во всех выделенных участках белого вещества по сравнению с контрольной группой (p &lt; 0,05). При анализе ROC-кривых наибольшие площади под ROC-кривыми (AUC) составили 0,892 ± 0,061 (83,3%; 88,89%) и 0,888 ± 0,054 (70,83%; 83,3%) у перивентрикулярной зоны и таламуса соответственно, что свидетельствует о “высокой” информативности данных моделей для детекции процесса гипомиелинизации у пациентов с АР.</p></sec><sec><title>Заключение</title><p>Заключение. Аффективные расстройства характеризуются значимым снижением МПФ белого вещества головного мозга в сравнении с группой контроля (p&lt;0,05), что свидетельствует о снижении концентрации миелина в исследуемых областях. Процесс гипомиелинизации является диффузным, так как был значимо выражен во всех выделенных регионах интереса у пациентов с аффективными расстройствами, включая перивентрикулярную область и область таламуса и базальных ядер в сравнении с контролем (p &lt; 0,05). Наибольшей диагностической ценностью для детекции гипомиелинизации при АР обладают изменения МПФ в перивентрикулярной зоне (PPV = 91%, NPV = 80%).</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Abstract</title><p>Abstract. This study aimed to test the method of fast molecular proton fraction mapping as a tool for quantitative assessment of myelin deficiency in affective disorders between general and local measurements in seven selected regions of interest of both hemispheres in comparison with the control group, determining the sensitivity and specificity of the method.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study included 24 patients with affective disorders, 13 were diagnosed with a current depressive episode as part of recurrent depressive disorder, and 11 were diagnosed with bipolar affective disorder. All patients underwent non-contrast magnetic resonance imaging of the brain using a fast MPF mapping protocol. Comparison of the MPF levels for the control and experimental groups were calculated using the Mann-Whitney U-test. ROC analysis was used to assess the prognostic value of the investigating parameters.</p></sec><sec><title>Results</title><p>Results. The average MPF indices of all selected regions of interest for the control group and group of patients with affective disorders (AD) were significantly different (p &lt; 0.0001). In a pairwise comparison of each selected area, patients with AD showed a significant decrease in MPF in all selected areas of white matter compared to the control group (p &lt; 0.05). Analyzing the ROC curves, the largest areas under the ROC curves (AUC) were 0.892 ± 0.061 (83.3%; 88.89%) and 0.888 ± 0.054 (70.83%; 83.3%) in the periventricular zone and thalamic area respectively. which indicates the “high” information content of these models for detecting the process of hypomyelination in patients with AR.</p></sec><sec><title>Conclusion</title><p>Conclusion. Affective disorders are characterized by a significant decrease in the MPF of the white matter of the brain in comparison with the control group (p &lt; 0.05), which indicates a decrease in the concentration of myelin in the observed areas. The process of hypomyelination is diffuse as it was significantly expressed in all selected regions of interest in patients with affective disorders, including the periventricular zone and the area of thalamus and basal ganglia in comparison with controls (p &lt; 0.05). MPF changes in the periventricular zone have the greatest diagnostic value for detecting hypomyelination in AD (PPV = 91%, NPV = 80%).</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>биполярное аффективное расстройство</kwd><kwd>гипомиелинизация</kwd><kwd>миелин</kwd><kwd>молекулярная протонная фракция</kwd><kwd>рекуррентное депрессивное расстройство</kwd></kwd-group><kwd-group xml:lang="en"><kwd>bipolar affective disorder</kwd><kwd>hypomyelination</kwd><kwd>myelin</kwd><kwd>molecular proton fraction</kwd><kwd>recurrent depressive disorder</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа поддержана грантом РНФ № 23-75-00023 «Поиск новых молекулярных механизмов аффективных расстройств с целью разработки методов диагностики и прогноза с использованием протеомных подходов и нейровизуализации».</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Malhi G.S., Das P., Outhred T. et al.
