Носительство мутации гена протромбина является одним из доказанных факторов риска развития гестационных осложнений.</p><p>Цель — определить эффективность гепаринопрофилактики преэклампсии и задержки роста плода (ЗРП), проводимой с прегравидарного периода у носительниц мутации F2G20210A при сверхпороговом повышении активности протромбина.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Проведено одноцентровое рандомизированное контролируемое исследование 80 беременных, носительниц мутации F2G20210A. Критерием включения в исследование явилась активность протромбина в плазме крови выше 171 %, определенная на прегравидарном этапе. Группу исследования составили 50 женщин (средний возраст — 31,2 ± 3,7 года), которым с фертильного цикла проводилась профилактика низкомолекулярным гепарином (НМГ) в повышенных профилактических дозах с учетом массы тела. В группу сравнения вошли 30 беременных (средний возраст — 31,3 ± 2,9 года), не получавших профилактику НМГ.</p></sec><sec><title>Результаты</title><p>Результаты. Применение НМГ в повышенных профилактических дозах у носительниц генотипа F2G20210A с уровнем активности протромбина выше 171 % с прегравидарного этапа позволило уменьшить абсолютный риск развития преэклампсии на 46,7 % (p = 0,0001; число пролеченных больных на одного излеченного (number needed to treat — NTT): 2,1, 95% ДИ: 3,4–1,56), в том числе тяжелой — на 30,7 % (p = 0,0001; NTT: 3,3; 95% ДИ: 6,7–2,2) и ЗРП — на 30,7 % (p = 0,0001; NTT: 3,3; 95% ДИ: 6,7–2,2).</p></sec><sec><title>Заключение</title><p>Заключение. При сверхпороговом повышении активности протромбина у носительниц генотипа F2G20210A для профилактики плацента-опосредованных осложнений обосновано использование НМГ.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. A prothrombin-mutant genotype is a known risk factor in gestational complications.</p><p>Aim — efficacy assessment in pregravid heparin prevention of pre-eclampsia (PE) and foetal growth retardation (FGR) in females with F2G20210A genotype and suprathreshold prothrombin activity.</p></sec><sec><title>Patients and methods</title><p>Patients and methods. A single-centre randomised controlled study enrolled 80 pregnant women carrying prothrombin F2G20210A. The inclusion criterion was a pregravid plasma prothrombin activity &gt; 171 %. The study cohort consisted of 50 women (mean age 31.2 ± 3.7 years) receiving low molecular-weight heparin (LMWH) in menstrual cycle at weight-based elevated prevention doses. A comparison group comprised 30 pregnant women (mean age 31.3 ± 2.9 years) not receiving LMWH prophylaxis.</p></sec><sec><title>Results</title><p>Results. A pregravid start of LMWH treatment at high prophylactic doses in F2G20210A genotype carriers with prothrombin activity &gt; 171 % allowed an absolute risk reduction (ARR) of PE by 46.7 % [p = 0.0001; number needed to treat (NNT): 2.1; 95 % confidence interval (CI) 3.4–1.56], severe PE by 30.7 % [p = 0.0001; NTT: 3.3; 95  % CI (6.7–2.2)] and FGR by 30.7 % [p = 0.0001; NTT: 3.3; 95 % CI (6.7–2.2)].</p></sec><sec><title>Conclusion</title><p>Conclusion. Use of LMWH is justified in prevention of placenta-mediated complications in F2G20210A genotype carriers with a suprathreshold-high prothrombin activity.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>мутация F2G20210A</kwd><kwd>активность протромбина</kwd><kwd>гепаринопрофилактика</kwd><kwd>надропарин кальция</kwd><kwd>плацента-опосредованные осложнения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>F2G20210A variant</kwd><kwd>prothrombin activity</kwd><kwd>heparin prevention</kwd><kwd>calcium nadroparin</kwd><kwd>placenta-mediated complications</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">Щербина Н.А., Макаренко М.В., Кузьмина И.Ю.
