Сведения о течении новой коронавирусной инфекции (COVID-19) у больных наследственными коагулопатиями ограничены. Основными вопросами являются: как наследственные коагулопатии влияют на течение COVID-19, и, наоборот, как COVID-19 влияет на течение наследственных коагулопатий.</p><p>Цель — анализ течения COVID-19 у больных наследственными коагулопатиями в России.</p></sec><sec><title>Методы</title><p>Методы. За период с 25.06.2022 по 31.07.2022 проведено поперечное опросное исследование, в которое были включены 187 больных наследственными коагулопатиями из разных городов и областей России. Использовали анкету на основе программного обеспечения для администрирования опросов (Google forms), включающую 27 вопросов.</p></sec><sec><title>Результаты</title><p>Результаты. Перенесли COVID-19 115 (62 %) из 187 опрошенных больных наследственными коагулопатиями. Дважды COVID-19 перенесли 22 (19 %) больных. Госпитализация потребовалась 14 (12 %) больным: 10 — с тяжелой гемофилией А, 1 — с гемофилией В среднетяжелой формы, 2 — с болезнью Виллебранда и 1 — с гипопроконвертинемией. Средний возраст госпитализированных больных составил 42 года. Во время COVID-19 геморрагический синдром в виде гемартрозов, экхимозов, гематом, носовых кровотечений, меноррагий, геморроидальных кровотечений, кровоизлияний в глазное яблоко отмечался у 9 (8 %) больных. Случаев тромбоза среди 115 переболевших COVID-19 не было. Среди больных наследственными коагулопатиями, переболевших COVID-19, по сравнению с больными, не болевшими COVID-19, болезнь Виллебранда встречалась статистически значимо чаще (р = 0,04). Изменения в течении основного заболевания после перенесенной COVID-19 констатировали 21 (18 %) из 115 больных: усиление болей в суставах отметили 11 (10 %) переболевших, 9 (8 %) жаловались на появление болей в суставах, которые ранее не беспокоили; изменения характера геморрагического синдрома описали 10 % больных.</p></sec><sec><title>Заключение</title><p>Заключение. Вероятность госпитализации больных наследственными коагулопатиями при COVID-19 старше 40 лет значимо выше. Болезнь Виллебранда может рассматриваться как потенциальный фактор риска COVID-19. Учитывая отсутствие случаев тромбозов в опрошенной группе, возможно, наличие гипокоагуляции у больных наследственными коагулопатиями является защитным механизмом, препятствующим возникновению тромботических осложнений при COVID-19.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Internationally published data about the course of COVID-19 in patients with congenital bleeding disorders (CBDs) are limited. There are questions about how COVID-19 affects the course of CBDs and, conversely, how CBDs affect the course of coronavirus infection.</p><p>Aim — to analyze the course of COVID-19 in patients with CBDs in Russia.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. A cross-sectional survey was conducted at the National Medical Research Center for Hematology (Moscow) for the period from June 25 to July 31, 2022. A cluster of 187 patients from different regions and cities of Russia were interviewed with a questionnaire based on survey administration software (Google forms) containing 27 questions.</p></sec><sec><title>Results</title><p>Results. COVID-19 affected 115 (62 %) of 187 surveyed patients and 22 (19 %) patients suffered from coronavirus infection twice. Hospitalization was required for 14 (12 %) patients with an average age of 42 years (10 patients with severe hemophilia A, 1 patient with moderate hemophilia B, 2 patients with von Willebrand disease and 1 patient with hypoproconvertinemia). During COVID-19 bleeding was observed in 9 (8 %) patients and was represented by hemarthrosis, ecchymosis, hematomas, nosebleeds, menorrhagia, hemorrhoidal bleeding, hemorrhage in the eyeball. There were no cases of thrombosis among 115 COVID-19 patients. Among patients with CBDs who had COVID-19, compared with patients who had not COVID-19, von Willebrand disease was statistically significantly more common (p = 0.04). Changes in the course of CBD after COVID-19 were noted by 21 (18 %) of 115 patients: 11 (10 %) of those who were ill noted increased joint pain, 9 (8 %) complained of joint pain that had not been previously experienced; 10 % of patients described changes of hemorrhagic syndrome.</p></sec><sec><title>Conclusion</title><p>Conclusion. The probability of hospitalization of patients with CBDs and COVID-19 older than 40 is statistically significantly higher. Von Willebrand disease can be considered as a potential risk factor for COVID-19. Given the absence of cases of thrombosis in the interviewed group of patients, the results of the study suggest that the presence of hypocoagulation in patients with CBDs may be a protective pathophysiological mechanism that prevents the development of COVID-19-associated thrombotic complications.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>наследственные коагулопатии</kwd><kwd>гемофилия</kwd><kwd>болезнь Виллебранда</kwd><kwd>новая коронавирусная инфекция</kwd><kwd>COVID-19</kwd><kwd>SARS-CoV-2</kwd><kwd>тромбоз</kwd></kwd-group><kwd-group xml:lang="en"><kwd>congenital bleeding disorders</kwd><kwd>hemophilia</kwd><kwd>von Willebrand disease</kwd><kwd>coronavirus infection</kwd><kwd>COVID-19</kwd><kwd>SARS-CoV-2</kwd><kwd>thrombosis</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">Tang N., Li D., Wang X., Sun Z.
