В развитии воспаления при инфицировании Н. pylori особое значение имеют реакции, вызванные продукцией цитокинов. Полиморфизм генов определяет уровень продукции соответствующих белков, который оказывает влияние на исход воспалительного процесса. При Н. pylori-ассоциированном гастрите преобладают провоспалительные цитокины. В работе проведен анализ полиморфизма гена ФНОα.</p><p>Цель – исследование влияния полиморфизмов гена ФНОα -308 G/A (rs1800629) на клинические особенности Н. pylori-инфекции в крупном промышленном центре России.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы.

Установлено, что риск заболеваний, ассоциированных с Н. pylori, выше у носителей генотипа GG ФНОα -308 G/А. Этот генотип свойственен пациентам с эрозивно-язвенными процессами в слизистой оболочке желудка и двенадцатиперстной кишки. Риск развития атрофического гастрита при инфицировании H. pylori связан с аллелем А и генотипом GA.</p></sec><sec><title>Заключение</title><p>Заключение. Исследование генетического полиморфизма ФНОα -308 G/A позволяет выделить лиц с высоким риском инфицирования H. pylori, возникновения деструктивных заболеваний желудка и двенадцатиперстной кишки и лиц с риском развития предраковых изменений слизистой в форме атрофического H. pylori-ассоциированного гастрита с целью проведения своевременной профилактики и лечения.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Reactions caused by cytokine production are of particular importance in the development of inflammation in H. pylori infection. The gene polymorphisms determine the corresponding protein production level, which affects the outcomes of inflammatory processes. In H. pyloriassociated gastritis, proinflammatory cytokines predominate. In the work were the TNFα gene polymorphisms analyzed.</p><p>The aim is to study the effect of TNFα -308 G/A (rs1800629) gene polymorphisms on the clinical features of H.pylori infection in a large industrial center of Russia.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. TNFα gene polymorphisms in patients with different forms of H. pylori infection were determined by allele-specific PCR.</p></sec><sec><title>Results</title><p>Results. It was found that the risk of H. pylori associated diseases is higher in carriers of the GG TNFα – 308 G/A genotype. This genotype is characteristic of patients with erosive and ulcerative processes in the mucous membrane of stomach and duodenum. The risk of developing atrophic gastritis when infected with H. pylori is associated with the A allele and the GA genotype.</p></sec><sec><title>Conclusions</title><p>Conclusions. The study of the TNFα -308 G/A genetic polymorphisms makes it possible to identify individuals with a high risk of H. pylori infection, the occurrence of destructive diseases of stomach and duodenum, and those at risk of developing precancerous mucosal changes in the form of atrophic H. pylori-associated gastritis in order to provide timely prevention and treatment.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Н. pylori-инфекция</kwd><kwd>полиморфизм генов</kwd><kwd>ФНОα</kwd><kwd>хронический гастрит</kwd><kwd>атрофия слизистой желудка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>H. pylori infection</kwd><kwd>gene polymorphism</kwd><kwd>TNFα</kwd><kwd>chronic gastritis</kwd><kwd>gastric mucosa atrophy</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">Sugano K., Tack J, Kuipers E.
