С  появлением нового класса препаратов мы столкнулись с  совершенно уникальным профилем токсичности. Спектр воздействия влияет на разнообразные проявления, которые затрагивают почти каждый орган и систему организма. Чаще всего поражаются кожа, железы внутренней секреции, желудочно-кишечный тракт, легкие, печень. Реже проявляются осложнения со стороны мочевыделительной, сердечно-сосудистой, мышечно-суставной, нервной и кроветворной систем. В данной статье рассмотрено одно из редких осложнений, которое возникает на фоне терапии ингибиторами контрольных точек иммунного ответа — тромбоцитопения с геморрагическим синдромом. Основная цель статьи  — повысить клиническую настороженность и  подчеркнуть актуальность проблемы редких осложнений на фоне иммунотерапии.</p></abstract><trans-abstract xml:lang="en"><p>Checkpoint inhibitors have radically changed the approach to oncology and have become the new standard of treatment for many solid tumors, significantly increasing the life expectancy of patients. With the advent of a new class of drugs, we are faced with a completely recognized toxicity profile. The spectrum affects other manifestations that affect almost every organ and system of the body. Most often the skin, the secretion of the internal gland, the gastrointestinal tract, lungs, and liver are affected. Complications from the urinary, cardiovascular, muscular-articular, nervous and hematopoietic systems occur less frequently. This article will discuss one of the rare complications that occurs during therapy with checkpoint inhibitors — thrombocytopenia with hemorrhagic syndrome. The main purpose of the article is to increase clinical alertness and highlight the relevance of the problem of rare complications during immunotherapy.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>иммунотерапия</kwd><kwd>ингибиторы контрольных точек иммунного ответа</kwd><kwd>редкие иммуноопосредованные нежелательные явления</kwd><kwd>тромбоцитопения на фоне терапии ингибиторами контрольных точек иммунного ответа</kwd></kwd-group><kwd-group xml:lang="en"><kwd>immunotherapy</kwd><kwd>immune checkpoint inhibitors</kwd><kwd>rare immune-mediated adverse events</kwd><kwd>thrombocytopenia during therapy with checkpoint inhibitors</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Дегтярёва Е.А., Проценко С.А., Иевлева А., Имянитов Е.Н.
