Currently, the use of thrombopoietin receptor agonists (TPO-RAs) is recommended as the second line therapy for ITP as it allows to achieve high platelet response (PR), including complete, in 73 % of cases of chronic ITP and in 87 % of cases of newly diagnosed disease. The mechanism of action differs for different TPO-RAs. Given this fact, in cases of resistance or intolerance to therapy with one TPO-RA, attempts are made to switch to another. The effectiveness of this approach for overcoming ITP resistance varies from 50 to 93 % according to various publications.</p><p><bold>   Aim. </bold>To assess the ability to achieve and maintain PR by switching from one TPO-RA to another in cases of resistance to the previous TPO-RA used in the second or subsequent lines of therapy.</p><p><bold>   Materials and methods. </bold>The analysis included 59 patients who were resistant (in 2 cases intolerance was also noted) to TPO-RA therapy (received after standard therapy) who were prescribed TPO-RA treatment with a different mechanism of action: switch from romiplostim to eltrombopag (25 patients) or vice versa (34 patients). Both groups were comparable in terms of demographic characteristics and median platelet level at the time of TPO-RA switching.</p><p><bold>   Results. </bold>PR was obtained in 76 % of cases, including complete response in 54 %, as a result of switching from one TPO-RA to another in 59 patients. Among 34 patients switched from eltrombopag to romiplostim, PR was achieved in 31 (91 %) patients, including complete response in 22 (65 %). Romiplostim was switched to eltrombopag in 25 patients, PR was achieved in 14 (56 %) with complete response in 10 (40 %).</p><p><bold>   Conclusion. </bold>The study showed that PR can be achieved and maintained through switching from one TPO-RA to an alternative.</p></abstract><trans-abstract xml:lang="ru"><p><bold>   Введение. </bold>Первичная иммунная тромбоцитопения (ИТП) – орфанное заболевание, характерный симптом которого – снижение числа тромбоцитов в крови, что в ряде случаев вызывает кровотечения различной степени. В настоящее время в качестве 2-й линии терапии ИТП рекомендовано применение агонистов тромбопоэтиновых рецепторов (аТПОр), которые позволяют достигнуть высокого уровня тромбоцитарного ответа (ТО), в том числе полного, в 73 % случаев при хронической ИТП и в 87 % – у вновь диагностированных пациентов. Механизм действия различных аТПОр различается. С учетом этого в случаях резистентности или непереносимости терапии одним из аТПОр проводятся попытки переключения на другой. Эффективность такого подхода при резистентности ИТП варьирует от 50 до 93 % по данным различных публикаций.</p><p><bold>   Цель исследования </bold>– оценить возможность достижения и сохранения ТО при переключении с одного аТПОр на другой в случае резистентности к предыдущему препарату, применяемому в качестве 2-й или последующих линий терапии.</p><p><bold>   Материалы и методы.</bold> В анализ включены 59 пациентов, имевших резистентность (в 2 случаях также непереносимость) к терапии аТПОр (получаемой после стандартной), которым назначали лечение аТПОр с другим механизмом действия: переключение с ромиплостима на элтромбопаг (25 пациентов) или наоборот (34 пациента). Обе группы сопоставимы между собой по демографическим характеристикам, медиане уровня тромбоцитов на момент переключения аТПОр.</p><p><bold>   Результаты.</bold> При переключении терапии у 59 больных получен ТО в 76 % случаев, в том числе полный ТО – в 54 %. Из 34 пациентов, переключенных с элтромбопага на ромиплостим, ТО достигнут у 31 (91 %), из них полный ТО – у 22 (65 %). Из 25 пациентов, переключенных с ромиплостима на элтромбопаг, ТО достигнут у 14 (56 %), из них полный ТО – у 10 (40 %).</p><p><bold>   Заключение. </bold>При переключении с одного аТПОр на альтернативный продемонстрирована возможность достижения и сохранения ТО.</p></trans-abstract><kwd-group xml:lang="en"><kwd>immune thrombocytopenia</kwd><kwd>thrombopoietin receptor agonist</kwd><kwd>romiplostim</kwd><kwd>eltrombopag</kwd><kwd>avatrombopag</kwd><kwd>switching</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>имунная тромбоцитопения</kwd><kwd>агонист тромбопоэтиновых рецепторов</kwd><kwd>ромиплостим</kwd><kwd>элтромбопаг</kwd><kwd>аватромбопаг</kwd><kwd>переключение</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The article was preparared based on the studies performed using the budgetary funds at the S.P.
