Однако значительная часть пациентов — около 20% неудовлетворительно реагируют даже на высокие дозы агонистов дофамина, что обусловлено резистентностью к терапии. Одной из причин развития резистентности к стандартному лечению является наличие ряда фармакодинамических характеристик. Клинические проявления персистирующей гиперпролактинемии обусловлены двумя патологическими факторами: гормональной гиперпродукцией и масс-эффектом аденомы гипофиза.</p><p>Предотвращение необратимых изменений возможно только при своевременном выявлении резистентности и определении оптимального персонализированного алгоритма лечения. Нами описан клинический случай опухолевой гиперпролактинемии, резистентной к терапии агонистами дофамина. Назначение комбинированного лечения тамоксифеном и агонистами дофамина позволило достичь улучшения состояния здоровья пациентки, нормопролактинемии и уменьшения размеров аденомы гипофиза. Гиперпролактинемия, обусловленная пролактин-секретирующей аденомой гипофиза, и ассоциированные с ней патологические проявления представляют собой значимую проблему, неблагоприятно влияющую на качество жизни отдельного пациента и демографическую ситуацию в целом. Это подчеркивает важность изучения причин и выявления предикторов резистентности. Результаты проводимого исследования, иллюстрированные клиническим примером, представлены в настоящей работе.</p></abstract><trans-abstract xml:lang="en"><p>The main treatment option of prolactin-secreting pituitary adenomas is dopamine agonist therapy, which demonstrates prolactin level normalizing and reducing the size of an adenoma in the majority of cases. However, significant amount of patients — about 20% — poorly responds even to high doses of dopamine agonists that is explained by the resistance to therapy. The occurrence of pharmacodynamic characteristics is one of the causes responsible for the development of resistance to typical therapy. Clinical manifestations of persistent hyperprolactinemia are due to following pathological factors: hormonal hypersecretion and the mass-effect of pituitary adenoma. Prevention of irreversible changes is possible only with timely detection of resistance and determination of the optimal personalized treatment algorithm.We report a clinical case of dopamine-agonist resistant microprolactinoma. Patient’s health stabilisation, normal level of prolactin and reduction in size of adenoma were achieved due to administration of combined treatment with tamoxifen and dopamine agonists. Hyperprolactinaemia occurring because of prolactin-secreting pituitary adenoma and associated adverse effects are significant problem, decreasing quality of life and demographics in general. This underlines the importance of figuring out causes and identifying predictors of the therapy resistance.The results of the study, illustrated by a clinical example, are presented in the present paper.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>аденома гипофиза</kwd><kwd>пролактинома</kwd><kwd>резистентность</kwd><kwd>хромато-масс-спектрометрия</kwd><kwd>персонализация лечения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pituitary adenoma</kwd><kwd>prolactinoma</kwd><kwd>resistance</kwd><kwd>chromatography-mass spectrometry</kwd><kwd>personalization of treatment</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Работа подготовлена в рамках гранта Министерства образования и науки Российской Федерации, соглашение 075-15-2022-310 от 20.04.2022</funding-statement></funding-group></article-meta></front><back><ref-list><ref id="cit1"><element-citation><name><surname>Melmed</surname> <given-names>Shlomo</given-names> </name> <name><surname>Casanueva</surname> <given-names>Felipe F.</given-names> </name> <name><surname>Hoffman</surname> <given-names>Andrew R.</given-names> </name> <name><surname>Kleinberg</surname> <given-names>David L.</given-names> </name> <name><surname>Montori</surname> <given-names>Victor M.</given-names> </name> <name><surname>Schlechte</surname> <given-names>Janet A.</given-names> </name> <name><surname>Wass</surname> <given-names>John A.
