При болезни Виллебранда (БВ) наряду с количественными характеристиками фактора Виллебранда (von Willebrand factor, vWF) внимание уделяется его качественным характеристикам.   Цель — оценка частоты встречаемости нарушений vWF с помощью тест-систем, содержащих коллаген I и III типа (vWF collagen binding activity vWF:CB type I — vWF:CBAI и type III — vWF:CBAIII), у женщин с диагностированной БВ 1-го типа и диагностических возможностей этих тестов.   Материалы и методы. В проспективное исследование включены 224 женщины с ранее диагностированной БВ 1-го типа. В образце венозной крови выполнялись исследования: антиген фактора Виллебранда (vWF:Ag), vWF:CBAI, vWF:CBAIII. Контрольную группу составили 80 здоровых женщин-доноров крови.   Результаты. У лиц контрольной группы значения показателей vWF:CBAI и vWF:CBAIII не выходили за пределы референсных интервалов. Снижение vWF:CBAI было выявлено у 133 (59,4 %) больных, WF:CBAIII — у 26 (11,6 %) больных. Изолированное снижение vWF:CBAI было выявлено у 87 (38,8 %) больных.   Заключение. Исследование vWF:CBAI и vWF:CBAIII представляется полезным в качестве дополнительного диагностического теста, позволяющего улучшить разграничение здоровых лиц и лиц с БВ.</p></abstract><trans-abstract xml:lang="en"><p>   Introduction. Along with the quantitative characteristics of the von Willebrand factor (vWF), more attention is paid to its qualitative characteristics in patients with von Willebrand disease (vWD).   Aim — to evaluate the frequency of vWF binding capacity disorders with type I collagen (vWF:CBAI) and type III collagen (vWF:CBAIII) in patients diagnosed with type 1 vWD and the diagnostic capabilities of these tests.   Material and methods. The prospective study included 224 female patients with previously diagnosed vWD type 1. The following tests were performed in the venous blood sample: von Willebrand factor antigen (vWF:Ag), vWF:CBAI, vWF:CBAIII. The control group consisted of 80 healthy female blood donors.   Results. In the control group, the values of vWF:CBAI and vWF:CBAIII did not exceed the reference intervals. A decrease in vWF:CBAI was detected in 133 (59.4 %) patients and vWF:CBAIII in 26 (11.6 %) patients. An isolated decrease in vWF:CBAI was detected in 87 (38.8 %) patients . An isolated decrease in vWF:CBAIII was less common — in 6 (2.7 %) patients.   Conclusion. The study of vWF:CBAI and vWF:CBAIII appears to be useful as an additional diagnostic test to improve the distinction between healthy individuals and those with VWD.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>фактор Виллебранда</kwd><kwd>vWF:CBAI</kwd><kwd>vWF:CBAIII</kwd><kwd>болезнь Виллебранда</kwd></kwd-group><kwd-group xml:lang="en"><kwd>von Willebrand factor</kwd><kwd>vWF:CBAI</kwd><kwd>vWF:CBAIII</kwd><kwd>von Willebrand disease</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование не имело спонсорской поддержки</funding-statement><funding-statement xml:lang="en">The study had no sponsorship</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Чернова Е.В.
