The control group included 100 relatively healthy subjects of comparable age. All patients were tested for classical aPL as well as IgG/IgM-anti-PS/PT by enzyme immunoassay.</p> <p><bold>Results.</bold> Based on the average values of IgG/IgM aPS/PT of the control group, the levels of positivity were allocated mean (<italic>M</italic>) + 3 or 5 standard deviations (<italic>SD</italic>): <italic>M</italic>+3<italic>SD</italic> and <italic>M</italic>+5<italic>SD</italic>. IgG aPS/PT levels above 73.6 U/ml (<italic>M</italic>+5<italic>SD</italic>) were more accurate diagnostic, for IgM aPS/PT – above 18.0 U/ml. IgG-aPS/PT were detected in 84 (44%) of 190 patients. Levels above diagnostic levels were detected in 68 (65%) of 104 patients with APS (55 with PAPS and 59 with SLE+APS). Thrombosis was significantly more common in patients with IgG aPS/PT compared with patients negative for IgG aPS/PT. Arterial but not venous thrombosis was associated with IgG aPS/PT positivity.</p> <p><bold>Conclusion. </bold>The frequency of detection of IgG aPS/PT in the examined patients was 44%, IgM aPS/PT – 29% and their combination – 19% of 190 patients. Half of the patients with probable APS had positive IgG aPS/PT and third – IgM aPS/PT. Median IgG aPS/PT were significantly higher in patients with APS compared to patients without APS and the control group. Thrombosis was associated with IgG aPS/PT. Arterial thrombosis was significantly more frequently reported in patients with IgG aPS/PT. The sensitivity of IgG aPS/PT for reliable APS at levels greater than 73.6 units/ml was 59%, specificity – 92%, for IgM aPS/PT – 35% and 91%, respectively.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель.</bold> Определить значение антител к комплексу фосфатидилсерин/протромбин (анти-ФС/ПТ) у пациентов с системной красной волчанкой (СКВ) и антифосфолипидным синдромом (АФС).</p> <p><bold>Материалы и методы. </bold>В исследование включены 190 пациентов: 123 (64,7%) с достоверной СКВ и 55 (29%) – с первичным АФС. Контрольную группы оставили 100 относительно здоровых человек, сопоставимых по возрасту. Всем пациентам исследовались классические антифосфолипидные антитела, а также иммуноглобулин (Ig)G/IgM-анти-ФС/ПТ иммуноферментным анализом.</p> <p><bold>Результаты. </bold>На основании средних значений IgG/IgM-анти-ФС/ПТ группы контроля выделены уровни позитивности – среднее арифметическое (<italic>М</italic>) + 3 или 5 стандартных отклонений (<italic>SD</italic>): <italic>М</italic>+3<italic>SD</italic> и <italic>М</italic>+5<italic>SD</italic>. Уровни IgG-анти-ФС/ПТ выше 73,6 Ед/мл (<italic>M</italic>+5<italic>SD</italic>) диагностически более точные, для IgМ-анти-ФС/ПТ – выше 18,0 Ед/мл. IgG-анти-ФС/ПТ выявлены у 84 (44%) из 190 пациентов. Уровни выше диагностических выявлялись у 68 (65%) из 104 пациентов с АФС (55 – с первичным АФС и 59 – с СКВ+АФС). Тромбозы достоверно чаще отмечались у пациентов с IgG-анти-ФС/ПТ по сравнению с пациентами, негативными по IgG-анти-ФС/ПТ. Артериальные, но не венозные тромбозы ассоциировались с позитивностью по IgG-анти-ФС/ПТ.</p> <p><bold>Заключение. </bold>Частота выявления IgG-анти-ФС/ПТ у обследованных пациентов составила 44%, IgМ-анти-ФС/ПТ – 29% и их сочетание – 19% из 190 больных. Медиана уровней IgG-анти-ФС/ПТ достоверно выше у пациентов с АФС по сравнению с пациентами без АФС и контрольной группой. Тромбоз ассоциировался с позитивностью IgG-анти-ФС/ПТ. Артериальные тромбозы значимо чаще регистрировались у пациентов с IgG-анти-ФС/ПТ. Чувствительность IgG-анти-ФС/ПТ для достоверного АФС при уровнях позитивности более 73,6 Ед/мл составила 59%, специфичность – 92%, для IgМ-анти-ФС/ПТ – 35 и 91% соответственно.</p></trans-abstract><kwd-group xml:lang="en"><kwd>antiphospholipid syndrome</kwd><kwd>systemic lupus erythematosus</kwd><kwd>antibodies to phosphatidylserine/prothrombin complex</kwd><kwd>antiphospholipid antibodies</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>антифосфолипидный синдром</kwd><kwd>системная красная волчанка</kwd><kwd>антитела к комплексу фосфатидилсерин/протромбин</kwd><kwd>антифосфолипидные антитела</kwd></kwd-group><funding-group><funding-statement xml:lang="en">This article was prepared as a part of Program FURS-2022-003 of Nasonova Research Institute of Rheumatology, Moscow, Russia.</funding-statement><funding-statement xml:lang="ru">Статья подготовлена в рамках фундаментальной программы ФГБНУ «НИИ ревматологии им.
