Венозные тромбозы у детей являются довольно редким состоянием, однако в последнее время отмечается увеличение количества случаев среди госпитализированных пациентов этой возрастной группы. Чаще всего тромбоз у детей возникает в результате воздействия различных факторов риска как наследственных, так и приобретенных, например, наличие центрального венозного катетера.</p><p>Цель исследования – оценить частоту встречаемости тромбофилии среди пациентов от 0 до 18 лет после перенесенного тромбоза глубоких вен (ТГВ).</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Из базы данных консультативного отделения НМИЦ ДГОИ им. Дмитрия Рогачева за период с 2017 по 2021 г. из общего числа визитов были выбраны пациенты в возрасте от 0 до 18 лет, которые перенесли объективно подтвержденный ТГВ и были обследованы для исключения тромбофилии. Из работы были исключены пациенты, у которых на момент анализа не был проведен полный спектр лабораторных исследований.</p><p>В зависимости от полученных результатов лабораторных исследований все пациенты были разделены на 2 группы: с тромбофилией и без нее. Для оценки статистической значимости различий между группами был использован критерий хи-квадрат.</p></sec><sec><title>Результаты</title><p>Результаты. В ходе анализа базы данных были выявлены 149 детей с ТГВ, из них 103 пациента были полностью обследованы для исключения тромбофилии и 46 человек не удалось дообследовать. Из 103 пациентов у 54 предрасположенность к тромбозу не подтвердилась, в то время как у 49 была диагностирована тромбофилия. Распространенность тромбофилии среди пациентов с ТГВ (n = 103) составила: дефицит протеина С – 3 %, дефицит антитромбина III – 4 %, дефицит протеина S – 4 %, антифосфолипидный синдром – 1 %, мутация FV Leiden – 7 %, мутация FII G20210A – 8 %, сочетанные – 8 %, другие – 13 % (повышение концентрации фактора VIII, липопротеина (а), гомоцистеина). При сравнении групп пациентов с тромбофилией и без нее по возрастному и половому составу, а также по различным клиническим характеристикам, таким как локализация и этиология тромбоза, статистически достоверных различий не получено.</p></sec><sec><title>Заключение</title><p>Заключение. Тромбофилии вносят вклад в возникновение тромбозов у детей. Результаты обследования на тромбофилию редко влияют на решения по лечению в остром периоде, поэтому важно понимать ограничения такого подхода. Тем не менее в некоторых случаях важно постараться выявить детей со склонностью к развитию тромбоза, поскольку эти пациенты могут быть кандидатами на профилактическую антикоагулянтную терапию в ситуациях высокого риска развития венозной тромбоэмболии.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Venous thrombosis is a rare condition in children, but now there is a significant increase in cases among hospitalized children. Thrombosis in children is a multifactorial disorder, there are various risk factors, both inherited and acquired, such as a central venous catheter.</p><p>The aim of the study is to evaluate the incidence of thrombophilia among patients aged 0 to 18 years after a history of deep vein thrombosis (DVT).</p></sec><sec><title>Materials and methods</title><p>Materials and methods. We have retrospectively analyzed the medical records of young patients (0–18 years) of from 2017 to 2021 of the Outpatient Consultative Unit of Dmitry Rogachev National Medical Research Center of Pediatric Hematology, Oncology and Immunology and selected patients with objectively confirmed DVT, who were examined to exclude thrombophilia. Patients who did not have a full range of laboratory tests were not accounted for in the study. The patients who had DVT during infancy had additional tests at the age older than one year.</p><p>All patients were divided into 2 groups: with and without thrombophilia. Chi-square test was used to assess the statistical significance of differences between groups.</p></sec><sec><title>Results</title><p>Results. We found 149 children with DVT: 103 patients were completely investigated for thrombophilia and a follow-up investigation is required for another 46 patients. Among 103 patients we didn’t confirm any prothrombotic condition in 54 of them, and thrombophilia was present in 49 patients. The prevalence of thrombophilia was estimated among children with DVT (n = 103): protein C deficiency – 3 %, antithrombin III deficiency – 4 %, protein S deficiency – 4 %, antiphospholipid syndrome – 1 %, mutation FV Leiden (hetero) – 7 %, FII G20210A (hetero) – 8 %, combined – 8 %, others – 13 % (increased concentration of fVIII, increased concentration of lipoprotein (a), high level of homocysteine).</p><p>While comparing groups of patients with and without thrombophilia by age and sex, and by various clinical characteristics (localization of thrombus, underline clinical condition and some others) no statistically significant differences were revealed.</p></sec><sec><title>Conclusion</title><p>Conclusion. Thrombophilias contribute to the occurrence of thrombosis in children. Results of thrombophilia screening rarely influence acute treatment decisions, so it is important to understand the limitations of this approach. Nevertheless, in some cases it is important to try to identify children with a tendency to develop thrombosis, since these patients may be candidates for prophylactic anticoagulation in situations of high risk of developing venous thromboembolism.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>тромбофилия</kwd><kwd>тромбофилия у детей</kwd><kwd>наследственность</kwd><kwd>тромбоз</kwd><kwd>венозные тромбозы</kwd><kwd>тромбозы у детей</kwd></kwd-group><kwd-group xml:lang="en"><kwd>thrombophilia</kwd><kwd>thrombophilia in children</kwd><kwd>heredity</kwd><kwd>thrombosis</kwd><kwd>venous thrombosis</kwd><kwd>thrombosis in children</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">Raﬃni L., Huang Y.S., Witmer C., Feudtner C.
