These complications include thromboembolic events that are considered to be rare and difficult-to-manage. Currently, the mechanisms and possible laboratory predictors of such complications are unclear. This paper presents our experience of using flow cytometry to assess the parameters of phosphatidylserine expression (detected by Annexin V binding) and describes impairments in the deformability of red blood cells (detected using forward and side scatter data) which determine the procoagulant properties of cells. According to our findings, the use of Annexin V for the assessment of gradual cell death in the samples of red blood cell (RBC) suspension is controversial. At the same time, our results show a higher sensitivity of the assessment of the accumulation of RBCs with an altered shape for the detection of programmed cell death - eryptosis. The obtained results can be used to improve the detection of dead RBCs during the routine storage of RBC suspension. The study was approved by the Independent Ethics Committee and the Scientific Council of the Dmitry Rogachev National Medical Research Center of Pediatric Hematology, Oncology and Immunology of Ministry of Healthcare of the Russian Federation.</p></abstract><trans-abstract xml:lang="ru"><p>Широкое применение препаратов крови неизбежно ведет к увеличению числа осложнений, связанных с ним. Одним из редких и трудноконтролируемых осложнений являются тромбоэмболические события. В настоящее время механизмы и возможные лабораторные предикторы таких осложнений неясны. В данной работе представлен опыт применения проточной цитофлуориметрии для оценки параметров экспрессии фосфатидилсерина (детектируемой по связыванию аннексина V) и описаны нарушения деформируемости эритроцита (детектируемого по данным прямого и бокового светорассеяния), которые обусловливают прокоагулянтные свойства клеток. Полученные результаты демонстрируют спорную возможность применения аннексина V для оценки процесса постепенной гибели клеток в образцах эритроцитной взвеси, одновременно показывая большую чувствительность оценки накопления эритроцитов измененной формы для детекции программируемой клеточной гибели - эриптоза. Результаты данной работы могут быть использованы для улучшения детекции погибших эритроцитов в рутинной практике хранения эритроцитной взвеси. Настоящее исследование одобрено независимым этическим комитетом и утверждено решением ученого совета ФГБУ «НМИЦ ДГОИ им. Дмитрия Рогачева» Минздрава России.</p></trans-abstract><kwd-group xml:lang="en"><kwd>red blood cell suspension</kwd><kwd>flow cytometry</kwd><kwd>phosphatidylserine</kwd><kwd>lactadherin</kwd><kwd>annexin V</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>эритроцитная взвесь</kwd><kwd>проточная цитофлуориметрия</kwd><kwd>фосфатидилсерин</kwd><kwd>лактадхерин</kwd><kwd>аннексин V</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Российский научный фонд</institution></institution-wrap><institution-wrap><institution xml:lang="en">Russian Science Foundation</institution></institution-wrap></funding-source><award-id>25-25-20101</award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>McDavid K., Lien R., Chavez Ortiz J., BradLey T., Luciano A., Griffin I., et aL.
