Dienogest (DNG) is considered a first-line treatment due to its comprehensive mechanism of action. However, there remains a lack of studies objectively assessing the dynamics of endometriotic lesions via magnetic resonance imaging (MRI) during DNG therapy. The need for such data, including evaluation of its effect on pain syndrome and ovarian reserve, defines the relevance of this study.</p> <p><bold>Aim. </bold>To assess the dynamics of endometriotic lesions, pain intensity, and ovarian reserve parameters in patients with endometriosis receiving DNG therapy.</p> <p><bold>Materials and methods. </bold>A prospective study was conducted involving 71 women with MRI-confirmed endometriosis (mean age 32.1 years) who were not indicated for surgical treatment. Patients received DNG 2 mg/day (Zafrilla®) continuously for at least 6 months (mean 8.5 months). Assessments performed before treatment initiation and after 6 months included: size of endometriotic lesions (deep endometriosis and endometriomas) using MRI; pain intensity; quality of life (SF-12 questionnaire); and serum levels of anti-Müllerian hormone (AMH), estradiol, and CA-125. Statistical analysis was performed using the Wilcoxon signed-rank test.</p> <p><bold>Results. </bold>DNG therapy resulted in a significant reduction in the volume of deep endometriosis foci by 4 times and endometriotic cysts by 5 times. A decrease in pain intensity was observed: the dysmenorrhea score decreased from 6.0 to 0 (<italic>p</italic> &lt; 0.0001), and the pelvic pain index decreased from 2.0 to 0.2 (<italic>p</italic> &lt; 0.0001). Pelvic pain was resolved in 93.2% of patients. AMH and estradiol levels showed no statistically significant change, while CA-125 levels decreased by half. The main adverse effect was acyclic bleeding (33.9%), which did not lead to therapy discontinuation in most cases.</p> <p><bold>Conclusion. </bold>Continuous DNG therapy demonstrated high efficacy in the regression of endometriotic lesions and improvement in the quality of life of patients with endometriosis. An important clinical advantage is the preservation of ovarian reserve during treatment. Thus, dienogest (Zafrilla®) can be considered an effective and safe option for the long-term conservative management of endometriosis.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold> Эндометриоз – хроническое рецидивирующее заболевание, требующее длительной медикаментозной терапии, особенно при отсутствии репродуктивных планов. Диеногест (ДНГ) считается препаратом терапии 1-й линии благодаря комплексному механизму действия. Однако недостаточно исследований, объективно оценивающих динамику эндометриоидных очагов с помощью магнитно-резонансной томографии (МРТ) на фоне терапии ДНГ. Необходимость в таких данных, включая оценку влияния на болевой синдром (БС) и овариальный резерв, определяет актуальность исследования.</p> <p><bold>Цель. </bold>Оценить динамику эндометриоидных очагов, интенсивности БС и показателей овариального резерва у пациенток с эндометриозом на фоне терапии ДНГ.</p> <p><bold>Материалы и методы. </bold>Проведено проспективное исследование, включающее 71 женщину с эндометриозом (средний возраст – 32,1 года), подтвержденным на основании данных МРТ органов малого таза, которым не показано хирургическое лечение. Пациентки получали ДНГ 2 мг в сутки (Зафрилла®) в непрерывном режиме не менее 6 мес (в среднем 8,5 мес). До начала терапии и через 6 мес оценивали: размеры очагов эндометриоза (глубокого эндометриоза и эндометриом) с помощью МРТ; интенсивность БС; качество жизни (по опроснику SF-12); уровни антимюллерова гормона (АМГ), эстрадиола и СА-125 в сыворотке крови. Статистический анализ выполняли с использованием парного критерия Уилкоксона.</p> <p><bold>Результаты. </bold>На фоне терапии ДНГ зафиксировано уменьшение объема очагов глубокого эндометриоза в 4 раза и эндометриоидных кист в 5 раз. Отмечено снижение интенсивности БС: балл дисменореи снизился с 6,0 до 0 (<italic>p</italic> &lt; 0,0001), индекс тазовой боли – с 2,0 до 0,2 (<italic>p</italic> &lt; 0,0001). У 93,2% пациенток тазовая боль была купирована. Уровень антимюллерова гормона и эстрадиола статистически не изменился, СА-125 снизился в 2 раза. Основным побочным эффектом были ациклические кровянистые выделения (33,9%), не приведшие в большинстве случаев к отмене терапии.</p> <p><bold>Заключение. </bold>Терапия ДНГ в непрерывном режиме продемонстрировала высокую эффективность в регрессе эндометриоидных очагов и улучшении качества жизни пациенток с эндометриозом. Важным клиническим преимуществом является сохранение овариального резерва на фоне лечения. Таким образом, прием ДНГ (Зафрилла®) можно рассматривать как эффективный и безопасный вариант консервативной терапии эндометриоза в перспективе для длительного использования.</p></trans-abstract><kwd-group xml:lang="en"><kwd>endometriosis</kwd><kwd>deep endometriosis</kwd><kwd>endometrioid ovarian cysts</kwd><kwd>dysmenorrhea</kwd><kwd>dienogest</kwd><kwd>magnetic resonance imaging</kwd><kwd>treatment tolerability</kwd><kwd>quality of life</kwd><kwd>pain measurement</kwd><kwd>ovarian reserve</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>эндометриоз</kwd><kwd>глубокий эндометриоз</kwd><kwd>эндометриоидные кисты яичников</kwd><kwd>дисменорея</kwd><kwd>диеногест</kwd><kwd>магнитно-резонансная томография</kwd><kwd>переносимость терапии</kwd><kwd>качество жизни</kwd><kwd>измерение выраженности боли</kwd><kwd>овариальный резерв</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The paper was prepared with the financial support of the pharmaceutical company Gedeon Richter (Hungary)</funding-statement><funding-statement xml:lang="ru">Материал подготовлен при финансовой поддержке фармацевтической компании «Гедеон Рихтер» (Венгрия)</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Becker CM, Bokor A, Heikinheimo O, et al.
