Initial average level of 25(OH)D in all pregnant women had no significant difference (16,45 ng/ml and 16,5 ng/ml, respectively). None of women of first group reached the final level of 25(OH)D corresponding to the value of the norm; 95,55% of patients in group 2 (n=43) reached the level of serum 25(OH)D 30 ng/ml (mean level of 39,11 ng/ml). Research has shown the efficacy of colecalciferol intake in doses of 2,000 IU, which may be recommended for pregnant women with 25(OH)D serum &lt;30 ng/ml.</p></abstract><trans-abstract xml:lang="ru"><p>В настоящей статье приведены результаты рандомизированного проспективного контролируемого исследования оценки насыщенности организма беременной витамином D с исходным дефицитом или недостатком 25(ОН)D в сыворотке. В 12-16 нед произведены первый забор крови и рандомизация. Проанализированы 2 группы женщин, которые ежедневно с I триместра до родов в течение 25 нед принимали колекальциферол в дозировке 500 МЕ (1-я группа, n=45) и 2000 МЕ (2-я группа, n=45). Исходный средний уровень 25(ОН)D у всех беременных не имел значимых различий (16,45 и 16,5 нг/мл соответственно). Ни у одной из женщин 1-й группы не был зарегистрирован итоговый уровень 25(ОН)D, соответствующий значению нормы; 95,55% пациентов 2-й группы (n=43) достигли уровня 25(ОН)D в сыворотке 30 нг/мл (средний уровень 39,11 нг/мл). Исследование показало эффективность применения 2000 МЕ колекальциферола, что может быть рекомендовано беременным женщинам с уровнем 25(ОН)D&lt;30 нг/мл в сыворотке крови.</p></trans-abstract><kwd-group xml:lang="en"><kwd>vitamin D</kwd><kwd>pregnancy</kwd><kwd>gestational complications</kwd><kwd>calcium</kwd><kwd>infant</kwd><kwd>miscarriage</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>витамин D</kwd><kwd>колекальциферол</kwd><kwd>25(ОН)D</kwd><kwd>беременность</kwd><kwd>гестационные осложнения</kwd><kwd>кальций</kwd><kwd>новорожденный</kwd><kwd>невынашивание</kwd><kwd>сolekalciferol</kwd><kwd>25(ОН)D</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>J Clin Endocrinol Metab 2013; 98: 2337-46.</mixed-citation></ref><ref id="B2"><label>2.</label><mixed-citation>De-Regil L.M, Palacios C, Ansary A et al.
