В зависимости от полиморфизма генов, влияющих на метаболизм, ответ пациентов на разнообразные варианты проводимой терапии может быть разным. Несмотря на потенциальное влияние rs7903146 TCF7L2 и rs1042714 ADRB2 на изменения состава тела при различных вариантах терапии ранних нарушений углеводного обмена, исследования данных ассоциаций ранее не проводились. Цель. Изучение влияния полиморфных маркеров rs7903146 TCF7L2, rs1042714 ADRB2 на изменение показателей состава тела пациентов при различных вариантах терапии ранних нарушений углеводного обмена.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В исследование были включены пациенты с избытком массы тела или ожирением и наличием факторов риска развития сахарного диабета 2 типа. В начале исследования пациентам были проведены генотипирование методом полимеразной цепной реакции в режиме реального времени, а также пероральный глюкозотолерантный тест и оценка состава тела методом биоимпедансометрии. Далее пациенты путем рандомизации были разделены на 2  терапевтические группы. Первая группа находилась на общепринятой при нарушениях углеводного обмена диетотерапии с исключением простых и ограничением сложных углеводов и жиров. Вторая группа в дополнение к диете получала терапию метформином. Через 3 мес всем пациентам повторно была проведена биоимпедансометрия.</p></sec><sec><title>Результаты</title><p>Результаты. В исследовании приняли участие 73 пациента (средний возраст — 48±12 лет, среднее значение ИМТ 34,27±6,18 кг/м2 ). Группу, соблюдавшую диетотерапию, составили 47 человек. В группу, получавшую метформин дополнительно к диетотерапии, вошли 26 человек. В группе пациентов, соблюдавших только лечебное питание, у пациентов, имеющих аллель Т rs7903146 TCF7L2, наблюдалось более эффективное снижение доли жировой массы тела по сравнению с гомозиготными носителями аллеля С (- 7,90±9,46% против -1,54±8,98%; p=0,027). Среди пациентов, соблюдавших диету и принимавших метформин, гомозиготных по аллелю С rs7903146 TCF7L2, имелась тенденция к более выраженному уменьшению окружности бедер по сравнению с носителями аллеля риска Т (-4,95±3,34% против -2,5±2,96%; p=0,064). Носители генотипа СС rs1042714 ADRB2, принимавшие метформин на фоне диеты, продемонстрировали более эффективное уменьшение объема бедер (-5,81±3,00% против -2,50±2,7%; p=0,009), а также тенденцию к снижению доли жировой массы организма (- 8,28±8,86% против -3,20±5,09%; p=0,068) и уменьшению окружности талии (-5,91±4,29% против -3,03±4,01%; p=0,091) по сравнению с носителями аллеля риска G. Несмотря на наличие ассоциации изучаемых однонуклеотидных замен с изменениями показателей жирового обмена, взаимосвязи rs7903146 TCF7L2 и rs1042714 ADRB2 в исследуемых терапевтических группах с изменениями массы тела в целом не прослеживалось (p&gt;0,05).</p></sec><sec><title>Заключение</title><p>Заключение. Однонуклеотидные полиморфизмы rs7903146 TCF7L2 и rs1042714 ADRB2 способны оказывать влияние на изменение жирового состава тела пациента при различных вариантах терапии ранних нарушений углеводного обмена.</p></sec><sec><title> </title><p> </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>BACKGROUND</title><p>BACKGROUND: Depending on the polymorphism of genes that that are involved in metabolism, the response of patients to different types of therapy may differ. Despite the potential effect of rs7903146 TCF7L2 and rs1042712 ADRB2 on changes in body composition in different types of therapy of early carbohydrate metabolism disorders, these associations haven’t been studied yet. AIM: To study the influence of rs7903146 TCF7L2, rs1042714 ADRB2 on changes in body fat composition in different types of therapy of early carbohydrate metabolism disorders.</p></sec><sec><title>MATERIALS AND METHODS</title><p>MATERIALS AND METHODS: The study involved patients with overweight or obesity and risk factors for Type 2 Diabetes development. All patients underwent genotyping with the real-time polymerase chain reaction, oral glucose tolerance test and bioimpedancemetry. Further, the patients were divided into two groups. First group kept a diet with the exclusion of simple and limitation of complex carbohydrates and fats. Second group took metformin in addition to the diet. Three months after bioimpedancemetry was performed again.</p></sec><sec><title>RESULTS</title><p>RESULTS: The research involved 73 patients (the mean age 48±12 y.o., the mean BMI 34,27±6,18 kg/m2 ). The diet therapy group consisted of 47 people. Other 26 patients took metformin in addition to the diet. In group of diet, T allele carriers of rs7903146 TCF7L2 were characterized with more decrease in fat mass compared with CC homozygotes (- 7.90 ± 9.46% vs. -1.54 ± 8.98%, p = 0.027). CC genotype carriers of rs7903146 TCF7L2 in group of metformin and the diet had a tendency for more decrease in hip circumference compared with T allele carriers (-4.95 ± 3.34% vs. — 2.5 ± 2.96%, p = 0.064). Carriers of C allele in homozygous state of rs1042714 ADRB2, who took metformin with the diet, demonstrated more decrease in hip circumference (- 5.81 ± 3.00% vs. -2.50 ± 2.7%, p = 0.009), the tendency for decrease in fat mass (-8.28 ± 8.86% vs. — 3.20 ± 5.09%, p = 0.068) and waist circumference (-5.91 ± 4.29% vs. -3.03 ± 4.01 %, p = 0.091) compared with G allele carriers. The association of rs7903146 TCF7L2 and rs1042714 ADRB2 with changes in total body weight was not observed (p&gt; 0.05).</p></sec><sec><title>CONCLUSION</title><p>CONCLUSION: Single nucleotide polymorphisms rs7903146 TCF7L2 and rs1042714 ADRB2 influence on body fat composition in patients with early carbohydrate metabolism disorders in various types of treatment.</p></sec><sec><title> </title><p> </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>полиморфизм</kwd><kwd>TCF7L2</kwd><kwd>ADRB2</kwd><kwd>метформин</kwd><kwd>биоимпедансометрия</kwd><kwd>нарушения углеводного обмена</kwd></kwd-group><kwd-group xml:lang="en"><kwd>рolymorphism</kwd><kwd>TCF7L2</kwd><kwd>ADRB2</kwd><kwd>metformin</kwd><kwd>bioimpedancemetry</kwd><kwd>carbohydrate metabolism disorders</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена на базах ГАУЗ «Городская поликлиника №18» Министерства здравоохранения РТ, Центральной научно-исследовательской лаборатории ФГБОУ ВО «Казанский ГМУ» Минздрава России с привлечением внебюджетных средств финансирования</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Дедов И.И., Шестакова М.В., Майоров А.Ю., и др.
