Это может привести к увеличению риска кровотечений. Одной из причин тромбоцитопении может быть прием лекарственных средств; в настоящее время задокументирована взаимосвязь ее развития с применением более чем 300 препаратов. Патогенез таких лекарственно-индуцированных тромбоцитопений (ЛИТ) описывается как следствие прямого цитотоксического воздействия лекарственного средства на мегакариоциты, приводящего к повышенному разрушению тромбоцитов в кровотоке или дисфункциональному тромбопоэзу. В диагностике ЛИТ ведущая роль принадлежит клиническому подходу: в первую очередь она осуществляется на основании данных лекарственного анамнеза и минимального комплекса лабораторных исследований, включающего подсчет количества тромбоцитов в крови и определение времени свертывания крови. Поскольку тромбоцитопения может быть сопряжена с риском серьезных кровотечений, ее своевременная диагностика имеет ключевое значение для определения тактики терапевтического вмешательства. Представлен клинический случай ЛИТ после совместного применения пациенткой препаратов разных групп – статина, ингибитора ксантиноксидазы, цитостатического препарата группы антиметаболитов, неселективного бета-адреноблокатора и двух нестероидных противовоспалительных средств с разным механизмом действия. Описанный случай показал, что во избежание полипрагмазии у пациентов с ЛИТ необходима оценка гемостатического потенциала методом низкочастотной пьезотромбоэластографии, так как в условиях недостаточного числа тромбоцитов они могут обеспечивать сохранную функциональную способность поддержания гемостаза.</p></abstract><trans-abstract xml:lang="en"><p>Thrombocytopenia is a condition in which the level of platelets in the blood decreases and becomes less than 150×109/L. This can lead to an increased risk of bleeding. One of the causes of thrombocytopenia may be medication; its association with the use of more than 300 drugs has now been documented. The pathogenesis of such, drug-induced thrombocytopenia (DITP), is described as a consequence of direct cytotoxic effects of drug on megakaryocytes, which leads to increased platelet destruction in the bloodstream or dysfunctional thrombopoiesis. In the diagnosis of DITP the leading role belongs to the clinical approach: first of all, it is carried out on the basis of data of drug history and a minimum set of laboratory tests, including counting the number of platelets in the blood and determining the clotting time. Since thrombocytopenia may be associated with the risk of serious bleeding, its timely diagnosis is of key importance for determining the tactics of therapeutic intervention. We present a clinical case of DITP, after the combined use of drugs of different groups – statin, xanthine oxidase inhibitor, cytostatic drug of antimetabolite group, non-selective beta- adrenoblocker and two non-steroidal anti-inflammatory drugs with different mechanism of action. The described case showed that to avoid polypharmacy in patients with DITP it is necessary to assess hemostatic potential by low-frequency piezotromboelastography, because even in conditions of insufficient platelet count they can provide preserved functional ability to maintain hemostasis.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>тромбоцитопения</kwd><kwd>полипрагмазия</kwd><kwd>гемостаз</kwd><kwd>цитостатическая терапия</kwd><kwd>метотрекса</kwd></kwd-group><kwd-group xml:lang="en"><kwd>thrombocytopenia</kwd><kwd>polypharmacy</kwd><kwd>hemostasis</kwd><kwd>cytostatic therapy</kwd><kwd>methotrexate</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке гранта РНФ № 22-15-20041 «Разработка технологии мониторинга гемостатического потенциала с оценкой эффективности его коррекции для предупреждения тромбо-геморрагических осложнений у полиморбидных пациентов в условиях коронавирусной инфекции COVID-19 и реконвалесценции».</funding-statement><funding-statement xml:lang="en">The work was supported by RSF grant № 22-15-20041 “Development of technology for monitoring haemostatic potential with evaluation of the effectiveness of its correction to prevent thrombo-haemorrhagic complications in polymorbid patients in conditions of coronavirus COVID-19 infection and reconvalescence”.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Gauer R.L., Whitaker D.J.
