It is primarily diagnosed clinically. A correct diagnosis of PD in its early stages is important for the development of a pathogenic treatment, which necessitates a search for potential biomarkers of the disease. We evaluated the diagnostic value of several microRNAs and their relationship with the clinical characteristics of PD. The study included 70 PD patients and 40 healthy volunteers. We analyzed the expression of 15 microRNAs in blood leukocytes, which were selected based on literature data and modern concepts of molecular PD pathogenesis. All patients were evaluated using the Hoehn and Yahr scale, UPDRS, NMSQ, and PDQ-39. The data analysis revealed a statistically significant increase in the expression of miR-7-5p, miR-29c-3p, and miR-185-5p and a statistically significant decrease in the expression of miR-29a-3p and miR-30c-1-5p in leukocytes in PD. However, the altered microRNA profile was shown to have a moderate diagnostic value for PD diagnosis. MicroRNA expression changes were associated with the motor and non-motor phenotypic features of PD and administration of anti-Parkinson’s drugs. Also, a relationship between some of the microRNAs studied and the duration and severity of PD was found, which may potentially be used to monitor disease progression.</p></abstract><trans-abstract xml:lang="ru"><p>Болезнь Паркинсона (БП) – одно из наиболее распространенных двигательных расстройств, диагностика которого до настоящего времени остается, главным образом, клинической. Для разработки патогенетического лечения БП важна точная диагностика БП на самых ранних стадиях, в связи с чем необходим поиск потенциальных биомаркеров заболевания. Нами оценена диагностическая значимость ряда микроРНК и их взаимосвязь с клиническими характеристиками БП. В исследование включены 70 пациентов с БП и 40 здоровых добровольцев. В лейкоцитах крови оценивали экспрессию 15 микроРНК, отобранных на основании опубликованных данных и современных представлений о молекулярном патогенезе БП. Всем пациентам проведена оценка по клиническим шкалам Hoehn–Yahr, UPDRS, NMSQ, PDQ-39. По результатам исследования выявлено статистически значимое повышение экспрессии miR-7-1-5p, miR-29c-3p и miR-185-5p и снижение экспрессии miR-29a-3p и miR-30c-1-5p в лейкоцитах при БП. Однако показано, что измененный профиль микроРНК обладает умеренной диагностической значимостью. Изменения экспрессии микроРНК были ассоциированы с моторными и немоторными фенотипическими особенностями БП и изменялись на фоне приема противопаркинсонических препаратов. Также показана связь ряда изученных микроРНК с длительностью и тяжестью БП, что потенциально может использоваться в мониторировании прогрессирования заболевания.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Parkinson’s disease</kwd><kwd>microRNA</kwd><kwd>biomarkers</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>болезнь Паркинсона</kwd><kwd>микроРНК</kwd><kwd>биомаркеры</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Coon E.A., Singer W. // CONTINUUM: Lifelong Learning in Neurology. 2020.
