К избыточному накоплению гомоцистеина (ГЦ) в крови и гипометилированию ДНК приводят полиморфные варианты генов фолатов, что способствует увеличению в ранние сроки невынашивания беременности (частота данной патологии составляет 20–25% от числа всех беременностей). Проведение периконцепционной профилактики индивидуальными дозами фолиевой кислоты снижает уровень свободного ГЦ в крови, но данная методика эффективна только при ее начале, за 3 месяца до зачатия и в ранние сроки развития эмбриона и плода (до 12 недель). Оценка лабораторных и клинических данных в ходе проводимого исследования подтвердила эффективность применения фолиевой кислоты (Элевит Пронаталь) в индивидуальной дозе 800 мкг в зависимости от уровня гипергомоцистеинемии за 16 недель до зачатия и в дозе 800 мкг 12 недель после зачатия.</p></abstract><trans-abstract xml:lang="en"><p>The problem of non-developing pregnancy (NB) remains relevant due to the rather wide spread of this complication and is due to the search for prognostically significant causes of this pathology, the development of adequate prevention of the detected disorders [1–4]. Polymorphic variants of folate genes lead to excessive accumulation of HC in the blood and hypomethylation of DNA, which contributes to an increase in early miscarriage (the frequency of this pathology is 20–25% of all pregnancies). Carrying out periconceptional prophylaxis with high doses of folic acidreduces the level of free HC in the blood, but this technique is effective only when it begins 3 months before conception and in the early stages of embryo and fetus development (up to 12 weeks). The evaluation of laboratory and clinical data in the course of the study confirmed the effectiveness of the use of folic acid at a dose of 800 mcg in a high risk group for the development of NB (pregnant women with hyperhomocysteinemia (GHZ)) 16 weeks before conception and 12 weeks after conception.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>неразвивающаяся беременность</kwd><kwd>кариотип</kwd><kwd>анеуплоидии</kwd><kwd>гомоцистеин</kwd><kwd>MTHFR677 TT</kwd><kwd>гипергомоцистеинемия (ГГЦ)</kwd><kwd>(Элевит Пронаталь)</kwd></kwd-group><kwd-group xml:lang="en"><kwd>missed miscarriage</kwd><kwd>karyotype</kwd><kwd>aneuploidy</kwd><kwd>homocysteine</kwd><kwd>MTHFR677 TT</kwd><kwd>hyperhomocysteinemia</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">МАРС: Неразвивающаяся беременность в анамнезе: реабилитация и подготовка к следующей гестации, Status Praesens 2021.</mixed-citation><mixed-citation xml:lang="en">MARS: Anamnesis of an undeveloped pregnancy: rehabilitation and preparation for the next gestation, Status Praesens 2021.</mixed-citation></citation-alternatives></ref><ref id="cit2"><label>2</label><citation-alternatives><mixed-citation xml:lang="ru">Мамий Д.Д., Татаркова Е.А., Тугуз А.Р., Цикуниб А.А., Сахтарьек З.Н.
