Фактор свертывания крови XII (FXII) является участником противоположных процессов гемостаза: контактной активации внутреннего пути свертывания крови и фибринолиза. Чем может быть представлена клиническая картина дефицита FXII: кровотечениями, тромбозами или протекать бессимптомно? Вопрос остается открытым.</p></sec><sec><title>Цель</title><p>Цель: представить клиническую и лабораторную характеристику российской популяции больных наследственным дефицитом фактора свертывания крови XII.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В ретроспективное исследование были включены 29 из 212 больных с дефицитом FXII, у которых проведен генетический анализ и подтвержден наследственный характер заболевания. Результаты. Среднее значение активированного частичного тромбопластинового времени в исследуемой группе составило 187 сек. Среднее значение активности FXII — 20%. Наиболее часто встречающейся мутацией F12 в российской популяции явилась нуклеотидная замена c.1681 –1 G&gt;A. Причинами обращения и диагностики заболевания послужили: предоперационное обследование у 9 (31%) больных, изменения в коагулограмме при обследовании перед планированием беременности или при обследовании по поводу хронического заболевания — у 8 (28%) больных; кровоточивость — у 7 (24%); изменения в коагулограмме при скрининге во время беременности — у 2 (7%), семейное обследование — у 2 (7%). У 21 (72%) из 29 больных клиническая картина была представлена геморрагическими проявлениями, в том числе у 6 больных были кровотечения в послеоперационном периоде. Тромботические события отмечены у 2 (7%) из 29 больных. Среди 16 (80%) женщин, имевших беременности в анамнезе, выкидыши случились у 6 (38%) из них.</p></sec><sec><title>Заключение</title><p>Заключение. Диагноз наследственного дефицита FXII наиболее часто устанавливают при предоперационном обследовании. Тем не менее 24% больных обратились к врачу с жалобами на геморрагические, преимущественно легкие или умеренные, проявления. Хирургические кровотечения отмечены у 21% больных. Акушерский анамнез более трети женщин отягощен выкидышами. У больных наследственным дефицитом FXII необходимо иметь настороженность в отношении спонтанной кровоточивости, хирургических кровотечений, невынашивания беременности и, в меньшей степени, тромбозов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. The blood coagulation factor XII (FXII) is involved in opposing processes of hemostasis: contact activation of the intrinsic pathway of blood coagulation and fibrinolysis. What might the clinical picture of FXII deficiency present with: bleeding, thromboses or be asymptomatic? The issue remains debatable.</p></sec><sec><title>Aim</title><p>Aim: To present the clinical and laboratory characteristics of patients with congenital FXII deficiency in the Russian population.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. A retrospective study included 29 of 212 patients with FXII deficiency who underwent genetic analysis, confirming the hereditary nature of the disease.</p></sec><sec><title>Results</title><p>Results. The mean APTT in the study group was 187 seconds (control 29–38 sec.). The mean FXII activity was 20%. The most common mutation of F12 in the Russian population was the nucleotide substitution c.1681 –1 G&gt;A. The reasons for contacting a hematologist and conducting diagnostics of the disease were: preoperative examination in 9 (31%) patients; abnormalities in the coagulogram during examination prior to pregnancy planning or during examination for a chronic disease in 8 (28%) patients; bleeding — in 7 (24%) patients; abnormalities in the coagulogram during screening in pregnancy in 2 (7%); family examination in 2 (7%) patients. In 21 (72%) of 29 patients, the clinical picture was represented by hemorrhagic manifestations. Thrombotic events were noted in 2 (7%) of 29 patients. Among 16 (80%) women with a history of pregnancy, miscarriages occurred in 6 (38%).</p></sec><sec><title>Conclusion</title><p>Conclusion. The diagnosis of hereditary FXII deficiency is most often established during preoperative examination. However, 24% of patients consulted a hematologist with complaints of hemorrhagic manifestations, mostly mild or moderate. Surgical bleeding was noted in 21% of patients. The obstetric history of more than a third of women was complicated by miscarriages. In patients with hereditary FXII deficiency, it is necessary to be wary of mild spontaneous bleeding, surgical bleeding, miscarriage and, to a lesser extent, thromboses.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>фактор свертывания крови XII</kwd><kwd>наследственный дефицит фактора свертывания крови XII</kwd><kwd>геморрагический синдром</kwd><kwd>кровотечение</kwd><kwd>тромбоз</kwd></kwd-group><kwd-group xml:lang="en"><kwd>blood coagulation factor XII</kwd><kwd>congenital factor XII deficiency</kwd><kwd>hemorrhagic syndrome</kwd><kwd>bleeding</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">Яковлева Е.В., Зозуля Н.И.
