Ген ABCB 1 кодирует P-гликопротеин, принадлежащий к семейству ABC-транспортеров. Ингибиторы протонной помпы (ИПП) являются субстратами P-гликопротеина. В исследованиях показано, что генетический полиморфизм ABCB 1 C 3435T может оказывать влияние на антисекреторное действие ИПП, а также на эффективность эрадикационной терапии. Изучение взаимосвязи носительства полиморфного маркера C 3435T гена ABCB 1 и клинических особенностей больных язвенной болезнью желудка и двенадцатиперстной кишки, принимающих ИПП, может иметь клиническое значение. Цель - установить связь между генетическим полиморфизмом C 3435T ABCB 1 и клиническими характеристиками больных язвенной болезнью желудка и двенадцатиперстной кишки, принимающих омепразол. Материалы и методы. В исследование были включены 50 пациентов с язвенной болезнью желудка и двенадцатиперстной кишки (19 мужчин, 31 женщин) в возрасте от 18 до 77 лет (в среднем 51,5±14,9 лет), получавших омепразол. У пациентов проводился забор 6 мл цельной крови в пробирки с К2-ЭДТА. Определение полиморфизма C 3435T гена ABCB 1 проводилось методом ПЦР в реальном времени. Результаты. Генотип CC по ABCB 1 был обнаружен у 11 (22 %) пациентов, генотип CT - у 26 (52 %) пациентов, генотип TT - у 13 (26 %) пациентов, что соответствует равновесию Харди-Вайнберга (p=0,77). Не было обнаружено статистически значимых различий в распределении генотипов CC, CT и TT по ABCB 1 у пациентов в зависимости от локализации язвы в желудке или двенадцатиперстной кишке (6,8 %, 15,9 %, 9,1 % против 13,6 %, 34,1 %, 20,5 % соответственно), наличия или отсутствия отягощенности семейного анамнеза по язвенной болезни (14,3 %, 33,3 %, 9,6 % против 4,7 %, 23,8 %, 14,3 % соответственно), наличия или отсутствия обострений язвенной болезни после установления диагноза (14,8 %, 18,6 %, 3,7 % против 11,1 %, 37 %, 14,8 % соответственно), наличия или отсутствия осложнений язвенной болезни в анамнезе (15,1 %, 9,1 %, 9,1 % против 12,1 %, 45,5 %, 9,1 % соответственно), диаметра язвы по данным ЭГДС менее 1 см или 1 см и более (7,1 %, 28,6 %, 28,6 % против 7,1 %, 7,1 %, 21,5 % соответственно), общего балла по шкале GSRS менее 30 или 30 и более (10 %, 30 %, 30 % против 5 %, 15 %, 10 % соответственно), тест Фишера, p&gt;0,05. Заключение. У пациентов с язвенной болезнью желудка и двенадцатиперстной кишки Московских ЛПУ отмечается высокая распространенность полиморфизма C 3435T гена ABCB 1. Не обнаружено взаимосвязи между носительством полиморфизма C 3435T гена ABCB 1 и клиническими данными пациентов с язвенной болезнью желудка и двенадцатиперстной кишки.</p></abstract><trans-abstract xml:lang="en"><p>Introduction. ABCB 1 gene localized on seventh chromosome encodes ABC-transporter P-glycoprotein. Proton pump inhibitors are known to be substrates of P-glycoprotein. Studies showed that C 3435T genetic polymorphism of ABCB 1 might influence proton pump inhibitors-based acid suppression and Helicobacter pylori eradication rates. From this point of view, studying the relation between C 3435T polymorphism of ABCB 1 and clinical and demographic features of peptic ulcer patients taking proton pump inhibitors may have clinical relevance. The aim of the study - to find the connection between C 3435T polymorphism of ABCB 1 and clinical and demographic features of patients with peptic ulcer taking omeprazole. Methods. Fifty peptic ulcer patients (19 men, 31 women), who were on treatment with omeprazole in Moscow clinics, aged 18-77 years (mean age 51.5±14.9 years) were enrolled. Six milliliters of venous blood were taken from patients in K2-EDTA tubes. C 3435T polymorphism of ABCB 1 gene was analyzed using real-time polymerase chain reaction (PCR). Results. CC genotype of ABCB 1 was found in 11 (22 %) patients, CT genotype - in 26 (52 %) patients, TT genotype - in 13 (26 %) patients. All genotypes were in Hardy-Weinberg equilibrium (p=0.77). There were no statistically significant differences in distribution of CC, CT, TT genotypes of ABCB 1 gene in patients depending on stomach or duodenum ulcer localization (6,8 %, 15,9 %, 9,1 % vs. 13,6 %, 34,1 %, 20,5 %, respectively), existence or absence of family history of peptic ulcer (14,3 %, 33,3 %, 9,6 % vs. 4,7 %, 23,8 %, 14,3 %, respectively), existence or absence of exacerbation after diagnosed peptic ulcer (14,8 %, 18,6 %, 3,7 % vs. 11,1 %, 37 %, 14,8 %, respectively), existence or absence of ulcer complications (15,1 %, 9,1 %, 9,1 % vs. 12,1 %, 45,5 %, 9,1 %, respectively), less than 1 cm or 1 cm and more ulcer according to gastroscopy (7,1 %, 28,6 %, 28,6 % vs. 7,1 %, 7,1 %, 21,5 %, respectively), less than 30 or 30 and more total score of GSRS scale (10 %, 30 %, 30 % vs. 5 %, 15 %, 10 %, respectively), Fisher’s Exact test, p&gt;0.05. Conclusion. There is a high prevalence of C 3435T polymorphisms of ABCB 1 gene in peptic ulcer patients of Moscow region. There were no statistically significant differences between ABCB 1 genotype and clinical and demographic features of peptic ulcer patients.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гликопротеин Р</kwd><kwd>фармакогенетика</kwd><kwd>ингибиторы протонной помпы</kwd><kwd>омепразол</kwd><kwd>язвенная болезнь</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ABCB 1</kwd><kwd>ABCB 1</kwd><kwd>P-glycoprotein</kwd><kwd>pharmacogenetics</kwd><kwd>proton pump inhibitor</kwd><kwd>omeprazole</kwd><kwd>peptic ulcer</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">Jażdżyk M, Sałagacka A, Zebrowska M, Balcerczak M, Mirowski M, Balcerczak E.
