Сочетание генетической предрасположенности с факторами окружающей среды и психоэмоциональным состоянием пациента играет ключевую роль в развитии синдрома раздраженного кишечника (СРК). Изучение ассоциации полиморфизмов генов с СРК может помочь в понимании доминирующих патофизиологических механизмов. На сегодня по данной теме опубликовано 11 метаанализов, однако среди них нет ни одного, который исчерпывающе обобщил бы данные о распространенности генетических полиморфизмов среди пациентов с СРК с преобладанием запора (СРК-З).</p></sec><sec><title>Цель</title><p>Цель: обобщение опубликованных данных о влиянии полиморфизмов генов на риск развития СРК-З.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Поиск литературы проводился в электронных базах PubMed и Scopus. На основе найденных исследований проводился метаанализ в соответствии с международными рекомендациями «Предпочитаемые элементы отчетности для систематических обзоров и метаанализов» (Preferred Reporting Items for Systematic Reviews and Meta-Analyses, PRISMA). В анализ включались работы, в которых изучалась ассоциация генетических полиморфизмов у пациентов, страдающих СРК-З.</p></sec><sec><title>Результаты</title><p>Результаты. Критериям включения соответствовали 34 исследования. Полученных данных оказалось достаточно для проведения метаанализа по полиморфизмам трех из перечисленных генов: SLC6A4 (10 статей), GNB3 (5 статей), ADRA2A (4 статьи). Не было выявлено статистически значимой ассоциации полиморфизма 5-HTTLPR гена SLC6A4 и полиморфизма C825T (rs5443) гена GNB3 как с СРК, так и с СРК-З. Была выявлена статистически значимая ассоциация полиморфизма 1291C&gt;G гена ADRA2A как с СРК, так и с СРК-З.</p></sec><sec><title>Выводы</title><p>Выводы. По данным проведенного нами метаанализа выявлена статистически значимая ассоциация полиморфизма 1291C&gt;G гена ADRA2A как с СРК, так и с СРК-З в смешанной популяции. Ни гомозиготный, ни гетерозиготный варианты полиморфизма 5-HTTLPR гена SLC6A4, а также полиморфизма C825T гена GNB3 не были ассоциированы ни с СРК-З, ни с СРК в целом.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Genetic predisposition in combination with environmental factors and the patient’s psychological and emotional state play a key role in the development of irritable bowel syndrome (IBS). Studies of association between genetic polymorphisms and IBS can help in understanding the key pathophysiological mechanisms. To date, 11 meta-analyses on this issue have been published, however, none of them comprehensively summarize the data on the prevalence of genetic polymorphisms in IBS with predominant constipation (IBS-C).</p></sec><sec><title>Aim</title><p>Aim: to summarize the published data on the impact of genetic polymorphisms on the risk of IBS-C.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. A literature search was performed in the PubMed and Scopus databases. Identified studies were used for a meta-analysis according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Publications investigating genetic polymorphisms in patients with IBS-C were included in this analysis.</p></sec><sec><title>Results</title><p>Results. A total of 34 studies met the inclusion criteria. The collected data were sufficient to conduct a meta-analysis on polymorphisms of three of the listed genes: SLC6A4 (10 articles), GNB3 (5 articles), ADRA2A (4 articles). No significant association was found between the SLC6A4 (5-HTTLPR) polymorphism, GNB3 c.825C &gt; T (rs5443) polymorphism and either IBS or IBS-C. It was found that ADRA2A 1291C&gt;G polymorphism was significantly associated with both IBS and IBS-C.</p></sec><sec><title>Conclusions</title><p>Conclusions. Our meta-analysis revealed that ADRA2A 1291C&gt;G polymorphism was significantly associated with both IBS and IBS-C in the mixed population. Neither homozygous nor heterozygous variants of the SLC6A4 (5-HTTLPR) polymorphism and GNB3 C825T polymorphism were associated with either IBS-C or IBS as a whole.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>генетическая предрасположенность</kwd><kwd>генные полиморфизмы</kwd><kwd>запор</kwd><kwd>синдром раздраженного кишечника</kwd><kwd>полиморфизм 5-HTTLPR</kwd></kwd-group><kwd-group xml:lang="en"><kwd>genetic susceptibility</kwd><kwd>genetic polymorphisms</kwd><kwd>constipation</kwd><kwd>irritable bowel syndrome</kwd><kwd>5-HTTLPR polymorphism</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">Mearin F., Lacy B.E., Chang L., Chey W.D., Lembo A.J., Simren M., et al.
