The decision to start treatment for ITP depends on several factors. The ITP treatment strategy is based on the clinical symptoms, with a focus on reducing the risk of severe bleeding and increasing platelet counts.</p><p><bold>   Aim. </bold>To evaluate the efficacy of 2<sup>nd</sup> line therapy with the thrombopoietin receptor agonist eltrombopag in patients with ITP.</p><p><bold>   Materials and methods. </bold>490 patients with ITP are under observation at the center for orphan diseases of M. F. Vladimirskiy Moscow Regional Research Clinical Institute. The present study included 186 patients with primary ITP after 1<sup>st</sup> line glucocorticosteroid therapy. eltrombopag, a thrombopoietin receptor agonist, was prescribed as the 2<sup>nd</sup> line of therapy.</p><p><bold>   Results.</bold> The median platelet count prior to eltrombopag therapy in all patients was 27.5 × 10<sup>9</sup> / l. after eltrombopag therapy, a significant (by 490 %) increase in platelet levels (median 135 × 10<sup>9</sup> / l) and a complete response according to clinical recommendations were noted.</p><p><bold>   Conclusion. </bold>Glucocorticosteroids (prednisolone, dexamethasone) remain the drugs of choice for the 1<sup>st</sup> line of therapy. Treatment with drugs of this group in most cases allows achieving an optimal platelet level and preventing bleeding. In case of inefficiency, intolerance, occurrence of side effects, the appointment of thrombopoietin receptor agonists eltrombopag or romiplostim is recommended. therapy with eltrombopag at a dose of 50 mg daily for several weeks has been able to achieve an increase in platelet levels, correct hemorrhagic syndrome, reduce the number of side effects during first-line glucocorticosteroid therapy, and improve the patient’s quality of life.</p></abstract><trans-abstract xml:lang="ru"><p><bold>   Введение. </bold>Иммунная тромбоцитопения (ИТП), или идиопатическая тромбоцитопеническая пурпура, является гематологическим аутоиммунным заболеванием, характеризующимся кровотечением и изолированным снижением количества тромбоцитов &lt;100 × 10<sup>9</sup> / л. Решение о начале лечения при ИТП зависит от нескольких факторов. Стратегия лечения ИТП основывается на клинических симптомах пациентов с акцентом на снижение риска тяжелых кровотечений и повышение числа тромбоцитов.</p><p><bold>   Цель исследования</bold> – оценить эффективность 2-й линии терапии агонистом тромбопоэтиновых рецепторов элтромбопагом у пациентов с ИТП.</p><p><bold>   Материалы и методы.</bold> В центре орфанных заболеваний МОНИКИ им. М. Ф. Владимирского под наблюдением находятся 490 пациентов с ИТП. В настоящее исследование были включены 186 пациентов с первичной ИТП после 1-й линии терапии глюкокортикостероидами. В качестве 2-й линии терапии пациентам был назначен агонист тромбопоэтиновых рецепторов элтромбопаг.</p><p><bold>   Результаты. </bold>Медиана уровня тромбоцитов до начала терапии элтромбопагом у всех больных составляла 27,5 × 10<sup>9</sup> / л. После терапии элтромбопагом отмечены значительное (на 490 %) повышение уровня тромбоцитов (медиана 135 × 10<sup>9</sup> / л) и достижение полного ответа согласно клиническим рекомендациям.</p><p><bold>   Заключение.</bold> Препаратами выбора 1-й линии терапии остаются глюкокортикостероиды (преднизолон, дексаметазон). Лечение препаратами данной группы в большинстве случаев позволяет добиться оптимального уровня тромбоцитов и предотвратить эпизоды кровотечения. При неэффективности, непереносимости, возникновении побочных эффектов рекомендовано назначение агонистов тромбопоэтиновых рецепторов элтромбопага или ромиплостима. Терапия элтромбопагом в дозе 50 мг ежедневно уже в течение нескольких недель позволяет добиться повышения уровня тромбоцитов, скорректировать геморрагический синдром, уменьшить число побочных явлений на фоне 1-й линии терапии глюкокортикостероидами и улучшить качество жизни пациента.</p></trans-abstract><kwd-group xml:lang="en"><kwd>immune thrombocytopenic purpura</kwd><kwd>immune thrombocytopenia</kwd><kwd>thrombocytopenia</kwd><kwd>romiplostim</kwd><kwd>eltrombopag</kwd><kwd>hemorrhagic syndrome</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>иммунная тромбоцитопеническая пурпура</kwd><kwd>иммунная тромбоцитопения</kwd><kwd>тромбоцитопения</kwd><kwd>ромиплостим</kwd><kwd>элтромбопаг</kwd><kwd>геморрагический синдром</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The study was performed without external funding</funding-statement><funding-statement xml:lang="ru">Исследование проведено без спонсорской поддержки</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Vrbensky J.
