Von Willebrand Factor and Its Role in Endothelial Dysfunction in Coronary Heart Disease

Objective: to study the probable laboratory predictors of aggressive multiple sclerosis.Materials and methods. Antibodies to myelin oligodendrocyte glycoprotein (MOG), antibodies to thyroperoxidase and markers of endothelial dysfunction in blood serum were determined in patients with multiple sclerosis (MS). These indicators were analyzed for different courses of the demyelinating process, for different severity of neurological disorders, and for various sizes of focal lesions on magnetic resonance images.Results. In patients with aggressive multiple sclerosis, higher titers of antibodies to both myelin oligodendrocyte glycoprotein and thyroperoxidase were detected. A relationship between von Willebrand factor (vWf) and matrix metalloproteinase-9 (MMP-9) and the stage of multiple sclerosis was identified. A higher level of matrix metalloproteinase-9 was detected in MS patients with active foci of the disease on magnetic resonance images.Conclusion. Thus, antibodies to myelin oligodendrocyte glycoprotein, antibodies to thyroperoxidase, the levels of von Willebrand factor, matrix metalloproteinase-9 and adhesion molecule sPECAM-1 can be used as laboratory predictors of the malignant course of multiple sclerosis.

Цель исследования-изучить ассоциации между маркерами эндотелиальной дисфункции, системного воспаления и агрегационными свойствами тромбоцитов у пациентов со стабильной стенокардией напряжения (ССН). Материалы и методы. Обследованы 100 пациентов со ССН, средний возраст-59,2±6,9 лет, получавших двойную антитромбоцитарную терапию (ДАТТ) в виде ацетилсалициловой кислоты (АСК) 75 мг и клопидогрела 75 мг. Полученные данные обследований (общеклинические, агрегометрии, уровень С-реактивного белка (СРБ), растворимого лиганда CD40, sP-селектина, фактора фон Виллебранда (ФВ), эндотелина-1 (ЭТ-1), эндотелийзависимой вазодилатация (ЭЗВД)) проанализированы с использованием программы «Statistica 10.0». Результаты. Выявлено 45 % пациентов с недостаточным ответом на ДАТТ (ПГ2) и 55 % с нормальным ответом (ПГ1). Уровень ЭТ-1, ФВ и СРБ был выше в ПГ2, по сравнению с ПГ1. ЭЗВД в ПГ1-2,4 [-8,9; 25,0] %, в ПГ2-8,4 [-19,2; 14,1] %, р<0,05. В ПГ2 преобладали пациенты с резко выраженным нарушением функции эндотелия (р=0,024 по точному тесту Фишера). Выводы. ДАТТ, проводимая АСК и клопидогрелем, эффективна у 55 % пациентов со ССН. У 45 % пациентов имеется недостаточный ответ на прием ДАТТ. Лабораторная резистентность к ДАТТ у пациентов со ССН многофакторна и ассоциирована с высокими уров
