Цель – оценить эффективность селективного модулятора рецепторов прогестерона улипристала ацетата (Эсмия) в предоперационной терапии больных миомой матки. Пациенты и методы. Обследованы 23 больных миомой матки в возрасте от 27 до 42 лет; 13 больным миомой матки в возрасте от 27 до 41 года с целью предоперационного лечения назначали Эсмию (5 мг/сут в течение 3 мес); 10 больных миомой матки в возрасте от 33 до 48 лет – группа контроля. Удаленные узлы миомы подвергались комплексному гистологическому исследованию, включающему иммуногистохимический анализ с использованием моноклональных антител к рецепторам эстрогенов и прогестерона, Кi-67, фосфогистону, Вах, Bcl-2, Cleaved caspase-3, сосудистому эндотелиальному фактору роста. Результаты. После 3 мес лечения препаратом Эсмия у всех 13 пациенток основной группы размеры миомы матки уменьшились в объеме соответственно 2–3 нед беременности, размеры доминантного узла сократились в среднем на 3±0,4 см в диаметре, в первом же цикле развилась аменорея (прекратились жалобы на обильные менструации). При этом не было отмечено никаких нежелательных явлений, женщины подчеркивали удобство использования препарата. При морфологическом исследовании обнаружены крупные очаги дистрофических изменений лейомиоцитов, малоактивные периваскулярные зоны роста, склероз псевдокапсулы, единичные фигуры митозов, выраженный апоптоз. С помощью анализа результатов иммуногистохимического исследования получены следующие данные: фосфогистон и Ki-67 – в единичных клетках; Bax – выраженная индукция; Cleaved caspase-3 – отчетливая экспрессия; сосудистый эндотелиальный фактор роста – слабо-умеренная экспрессия; свободных рецепторов прогестерона – 78–87%. Заключение. Доказано, что под действием улипристала ацетата уменьшается количество и размер гладкомышечных клеток лейомиомы матки, усиливается апоптоз, при этом окружающий миометрий под действием Эсмии не изменяется. Клинически размеры миоматозных узлов и самой матки уменьшаются. Подтвержден механизм регрессионного воздействия улипристала ацетата (Эсмии) на миому матки как селективного тканеспецифичного «неэффективного» конформатора рецепторных белков, подавляющего транскрипцию прогестерона в клетках миомы матки.
The objective. To assess the effectiveness of the selective progesterone receptor modulator ulipristal (Esmya) in presurgicaltherapy of patients with uterine myoma. Patients and methods. The examination included 23 patients with uterine myoma aged 37 to 42 years, 13 patients with uterine myoma aged 21 to 41 years who received Esmya (5 mg/day for 3 months) as a presurgical treatment, 10 patients with uterine myoma aged 33 to 48 years – control group. Removed myoma nodules underwent complex histological examination that included immunohistochemical testing with the use of monoclonal antibodies to estrogen and progesterone receptors; Кi-67; phospho-histone; Вах; Bcl-2; cleaved caspase-3; VEGF. Results. After a 3-month Esmya therapy in 13 patients, the sizes of uterine myoma decreased to correspond to 2–3 wks of gestation, the sizes of the dominant nodule were reduced on the average by 3±0,4 cm in diameter, amenorrhea developed as soon as in the first cycle (complaints of profuse menstrual bleeding stopped). No undesirable effects were noted, the women pointed out to the convenient use of the drug. A morphological examination found large sites of dystrophic changes of leiomyocytes; low-active perivascular growth areas; pseudocapsule sclerosis, single mitotic figures, and marked apoptosis. Analysis of the results of immunohistochemical examination found the following results: phospho-histone and Ki-67 – in single cells; Bax – marked induction; cleaved caspase-3 – distinct expression; VEGF – weak-to-moderate expression; expression of progesterone – 78–87%. Conclusion. As has been demonstrated a decreasing of proliferation and hypertrophy of smooth muscle cells of uterine myoma, under the influence of Esmya; while the surrounding myometrium does not change. The mechanism of the regression effect of Esmya on uterine myoma has been confirmed as a selective tissue-specific «noneffective» receptor protein conformator, inhibiting transcription of progesterone in cells of uterine myoma.
Key words: leyomyoma of womb, smooth muscle cells of uterine myoma, mitoses, proliferation, apoptozis,the selective modulators of the receptors of progesterone, ulipristal acetate (Esmya).
