The diagnosis of MF is based on the following criteria: comprehensive assessment of the clinical picture of the disease, histological and immunohistochemical examination of the skin, and determination of rearrangement of the T-cell receptor gene, but even this does not always aid in diagnosis. The aim of the study is to investigate the expression of micro-RNAs (miR-223, -423, -663, -16, -326, -711) in the blood plasma and leukocytes of patients with a presumptive diagnosis of MF to improve the disease diagnosis.<bold> Methods.</bold> This study included 50 patients aged 24 to 79 years, of whom 30 patients had a preliminary diagnosis of MF and 20 patients with small plaque parapsoriasis, who formed the comparison group. All patients underwent histological, immunohistochemical examination of skin biopsies, and determination of micro-RNA (miR-223, -423, -663, -16, -326, -711) expression in blood plasma and leukocytes by real-time PCR. <bold>Results.</bold> Analyzing the results of clinical-anamnestic, histological, and immunohistochemical research methods, the diagnosis of MF was established in 22 of 30 (73.3%) patients, of which 9 of 14 (64.3%) were in the early stages of the disease. small plaque parapsoriasis. <bold>Conclusion.</bold> During our study, it was found that the studied micro-RNAs (miR-326, -663, -711, -223, -423, -16) in the blood plasma and leukocytes of patients with MF have statistically significant levels of expression compared to the low level of expression of these micro-RNAs in patients with small plaque parapsoriasis. The expression of micro-RNAs we studied in the skin contributes to the improvement of MF diagnosis with an accuracy of up to 90%.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold><italic> </italic>Ранняя диагностика грибовидного микоза (ГМ) как наиболее часто встречающейся формы Т-клеточной лимфомы представляет большие трудности. Диагностика ГМ осуществляется на основании следующих критериев: комплексной оценки клинической картины заболевания, гистологического и иммуногистохимического исследования кожи и определения реаранжировки гена Т-клеточного рецептора, но даже это далеко не всегда помогает в постановке диагноза. <bold>Цель исследования</bold> — изучить экспрессию микро-РНК (miR-223, -423, -663, -16, -326, -711) в плазме крови и лейкоцитах у больных с предположительным диагнозом ГМ для совершенствования диагностики заболевания. <bold>Методы.</bold> В данное исследование было включено 50 пациентов в возрасте от 24 до 79 лет, из них 30 пациентов — с предварительным диагнозом ГМ и 20 пациентов с мелкобляшечным парапсориазом, которые составили группу сравнения. Всем пациентам провели гистологическое, иммуногистохимическое исследование биоптатов кожи и определение экспрессии микро-РНК (miR-223, -423, -663, -16, -326, -711) в плазме крови и лейкоцитах методом ПЦР в режиме реального времени. <bold>Результаты.</bold> Анализируя результаты проведенного клинико-анамнестического, гистологического и иммуногистохимического методов исследования, диагноз ГМ был установлен у 22 (73,3%) из 30 пациентов, из них у 9 (64,3%) из 14 — на ранней стадии заболевания мелкобляшечным парапсориазом. <bold>Заключение. </bold>В ходе проведенного нами исследования удалось установить, что изучаемые микро-РНК (miR-326, -663, -711, -223, -423, -16) в плазме крови и лейкоцитах больных ГМ имеют статистически значимые уровни экспрессии по сравнению с низким уровнем экспрессии этих микро-РНК у больных мелкобляшечным парапсориазом. Экспрессия изучаемых нами микро-РНК в коже способствует совершенствованию диагностики ГМ с точностью до 90%.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Mycosis fungoides</kwd><kwd>small - plaque parapsoriasis</kwd><kwd>micro-RNA</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>грибовидный микоз</kwd><kwd>мелкобляшечный парапсориаз</kwd><kwd>микро-РНК</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Первый Московский государственный медицинский университет имени И.М.
