Цель исследования: изучить частоты генотипов и аллелей полиморфизма 174G/C (rs1800795) гена IL6 и полиморфизма -511C/T (rs16944) гена IL1В, а также их связь с биомаркёрами атрофии у пациентов с РЖ в клиническом исследовании «случай-контроль». Материалы и методы исследования: в исследование вошли 80 человек с РЖ (45 мужчин и 35 женщин, средний возраст 61,0 ± 13,4 лет), лечившихся в 2-х лечебных учреждениях («случаи»). В качестве «контроля» из базы многоцентрового когортного исследования HAPIEE были использованы образцы ДНК 87 человек, подобранных к «случаям» по полу и возрасту. Выделение ДНК из венозной крови проводили методом фенол-хлороформной экстракции. Образцы ДНК генотипировали по опубликованным методикам. Образцы сыворотки тестировали с помощью набора диагностикумов для иммуноферментного анализа с определением уровней пепсиногена I (ПГI), ПГII, соотношения ПГI/ПГII, гастрина-17 и IgG антител к H.рylori. Результаты: в общей группе не найдено связи полиморфизмов 174 G/C гена IL6 и -511C/T гена IL1В с РЖ. Однако у женщин частота G/G генотипа гена IL6 оказалась в 2 раза выше в группе с РЖ, чем в контроле (р=0,03). У пациентов с признаками фундальной атрофии генотип G/G встречался в 2 раза чаще, чем гомозиготный вариант генотипа С/С (р=0,002). У пациентов с РЖ генотип с редким аллелем Т (С/Т + Т/Т) гена IL1B встречался достоверно чаще, чем гомозиготный С/С вариант (р=0,03). У пациентов с РЖ и отсутствием признаков фундальной атрофии (ПГI более 30 мкг/л) редкий гомозиготный вариант генотипа Т/Т встречался достоверно реже: 11,3% против 47,2% (генотип С/Т) и против 41,5% (генотип С/С) (р&lt;0,001). Выводы: Полученные данные позволяют предполагать связь изученных полиморфизмов с формированием ракового фенотипа гастрита, что требует дальнейшего изучения их значимости (веса) в рискометрии РЖ.</p></abstract><trans-abstract xml:lang="en"><p>Background: Genetic polymorphism of some inflammatory cytokines is associated with the risk of developing specific, H. pylori-associated diseases, including gastric cancer (GC). Aim: To study the genotypes and alleles frequencies of polymorphism 174G / C (rs1800795) of the IL6 gene and polymorphism -511C / T (rs16944) of the IL1B gene, as well as their association with biomarkers of atrophy in patients with GC in the clinical «case-control» study. Materials and methods: 80 patients with GC (45 mails and 35 females with an average age of 61.0 ± 13.4 years) from two medical centers were studied. In the control, DNA samples from 87 subjects were matched by sex and age from the base of the multicenter cohort study HAPIEE. DNA was isolated from venous blood using phenol-chloroform extraction. DNA samples were genotyped according to published methods. Serum samples were tested using a diagnostic kit for enzyme-linked immunosorbent assays to determine the levels of pepsinogen I (PGI), PGII, PGI/PGII ratios, gastrin-17 and IgG antibodies to H. pylori. Results: In the general group, association of polymorphisms of 174 G/C of the IL6 gene and the -511C/T gene of the IL1B gene with the GC was not found. However, in women, the frequency of the G/G genotype of the IL6 gene was 2 times higher in the group with G/C than in the control (p=0.03). In patients with corpus atrophy, the G/G genotype was revealed twice as often as homozygous C/C variant of the IL6 gene (p=0.002). In patients with GC, the genotype with a rare T allele (C/T + T/T) of the IL1B gene was significantly more frequent than the common homozygous C/C variant (p=0.03). The rare homozygous T/T genotype was significantly less frequent in patients with GC and no signs of corpus atrophy (PGI &gt;30 μg/l): 11.3% vs 47.2% (C/T genotype) and vs 41.5% (genotype C/C) (p &lt;0.001). Conclusions: The received data allow assuming the possible connection of studied polymorphisms with the formation of a cancer phenotype of the gastritis, which requires further study of their significance (weight) in the GC riskometry.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рак желудка</kwd><kwd>полиморфизм</kwd><kwd>пепсиногены</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rs1800795</kwd><kwd>rs16944</kwd><kwd>IL6</kwd><kwd>IL1В</kwd><kwd>H.pylori</kwd><kwd>gastric cancer</kwd><kwd>polymorphism</kwd><kwd>rs1800795</kwd><kwd>rs16944</kwd><kwd>IL6</kwd><kwd>IL1B</kwd><kwd>pepsinogenes</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">Crew K.
