Проблемой применения рекомбинантного активированного фактора свертывания крови VII (rFVIIa) при ингибиторной гемофилии является сложность лабораторной оценки  терапии. Стандартные клоттинговые тесты изменяются, однако, как правило, не нормализуются.</p><p>Цель работы – изучить возможность использования стандартных клоттинговых тестов (активированного частичного тромбопластинового времени (АЧТВ), протромбинового  времени (ПВ)) для оценки эффективности гемостатической терапии rFVIIa у больных с ингибиторной гемофилией.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В исследование были включены 20 взрослых больных с ингибиторной гемофилией. На момент включения в исследование у пациентов не было  признаков кровотечения, FVIII в плазме был &lt; 1 %, ингибитор к FVIII – в титре от 5 БЕ/мл до 463 БУ/мл. Больные получали однократно rFVIIa (Коагил-VII) в дозе 90 мкг/кг. До введения rFVIIa, а затем через 15, 30 и 60 мин, 2 и 24 ч исследовали АЧТВ, ПВ, эндогенный тромбиновый потенциал (ЭТП), проводили тромбоэластографию (ТЭГ).</p></sec><sec><title>Результаты</title><p>Результаты. Исходно у всех больных было удлиненное АЧТВ, которое уменьшилось через 15 мин после введения rFVIIa и сохранялось значимо меньше до 120 мин, но оставалось  почти в 2 раза выше нормы. ПВ также значимо уменьшилось через 15 мин после rFVIIa. На ТЭГ до введения rFVIIa сгусток не образовывался, через 15 мин после инъекции параметры ТЭГ приблизились к норме, гемостатический эффект сохранялся 2 ч. ЭТП повысился через 15 мин после применения rFVIIa, повышение сохранялось в течение 60 мин. Имелась  сильная корреляция между временем от начала измерения до образования первых волокон  фибрина (R) и АЧТВ (r = 0,74; p = 0,001), максимальной амплитудой (МА) и АЧТВ (r = – 0,70), между ПВ и R (r = 0,79; p = 0,01), ПВ и МА (r = –0,76, p = 0,01). Не было корреляции между ЭТП и АЧТВ, ЭТП и R. С помощью ROC-анализа установлено, что укорочение АЧТВ  после введения rFVIIa на 17 с и более или на 22 % и более от исходной величины  ассоциируется с нормализацией R и МА. Изменения ПВ хуже позволяли дискриминировать нормальные значения ТЭГ.</p></sec><sec><title>Заключение</title><p>Заключение. Укорочение АЧТВ после введения rFVIIa у больных с ингибиторной гемофилией на 17 с и более или на 22 % и более от исходной величины может быть  использовано для оценки эффективности гемостатической терапии rFVIIa в случаях, когда невозможно или недоступно выполнение ТЭГ.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. The Problem of the use of recombinant activated factor VII (rFVIIa) in hemophilia patients with inhibitors is the complexity of the laboratory evaluation of the therapy. After rFVIIa  administration standard clothing tests are changing, however, are not normalized.</p><p>The aim of this study was to investigate the possibility of using standard clothing tests (activated partial thromboplastin time (APTT) and prothrombin time (PT)) to assess the efficiency of hemostatic  therapy with rFVIIa in hemophilia patients with inhibitors. The aim of this work is to investigate the possibility of using standard clothing  tests (activated partial thromboplastin time (APTT), prothrombin time (PT)) to assess the efficiency of hemostatic  therapy with rFVIIa in patients with inhibitory hemophilia.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. 20 male hemophilia patients with inhibitors were included in the study. At the time of study inclusion  none patients had signs of bleeding. Plasma levels of FVIII were &lt; 1  %, FVIII inhibitor titers were from 5 BU/ml to 463 BU/ml. All  patients received rFVIIa (Coagil-VII) at a dose of 90 μg/kg. Before  the administration of rFVIIa and then in 15, 30 and 60 min, 2 and 24 h the APTT, the PT, the endogenous thrombin potential (ETP) and thromboelastography (TEG) parameters (reaction time – R, maximum amplitude – MA) were evaluated.</p></sec><sec><title> </title><p> </p></sec><sec><title>Results</title><p>Results. Before rFVIIa administration all patients had prolonged APTT. 15 min after administration of rFVIIa APTT shortened and remained shorter than baseline level, but 2 times longer than  normal ranges during 2 hours. The PT also significantly decreased in  15 min after the rFVIIa administration. Prior to treatment patients had minimal to no clotting detectable by TEG. Administration of rFVIIa led to normalization of TEG traces in the most of the patients  in 15 min. Elevated by TEG hemostatic effects persisted for 2 h. The  ETP increased in 15 min after rFVIIa administration. This increase of  ETP persisted for 60 min. There were strong correlations between R  and APTT (r = 0.74; p = 0.001), between MA and APTT (r = 0.70),  between PT and R (r = 0.79; p = 0.01), PT and MA (r = 0.76; p =  0.01). There were no correlations between ETP and APTT, and  between ETP and R. The shortening of the APTT after rFVIIa administration for 17 s and more or for 22 % and more from the baseline levels were associated with the normalization of R and MA.  Changes of the PT poorly allowed to discriminate normal values of  TEG.</p></sec><sec><title>Conclusion</title><p>Conclusion. Shortening of the APTT after rFVIIa administration in hemophilia patients with inhibitor for 17 s and more or for 22 % and more from the initial value can be used to assess the hemostatic efficiency of rFVIIa therapy.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>гемофилия</kwd><kwd>ингибиторная форма</kwd><kwd>активированное частичное тромбопластиновое время</kwd><kwd>протромбиновое время</kwd><kwd>тест генерации тромбина</kwd><kwd>тромбоэластография</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hemophilia</kwd><kwd>inhibitory form</kwd><kwd>activated partial thromboplastin time</kwd><kwd>prothrombin time</kwd><kwd>thrombin generation test</kwd><kwd>thromboelastography</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">Hender R.U., Lee C.A.
