Инфицированность Helicobacter pylori (НР), являющегося канцерогеном 1-го класса развития рака желудка, в мировой популяции остается высокой. В настоящее время эрадикационная терапия (ЭТ) рассматривается как наиболее актуальная стратегия профилактики рака желудка. В связи с низкими показателями частоты эрадикации при использовании тройной схемы на основе кларитромицина рекомендовано добавление солей висмута и использование удвоенных дозировок ингибиторов протонной помпы. Цель: оценить эффективность удвоенных дозировок эзомепразола и рабепразола у пациентов с различными генотипами цитохрома Р450 2C19, инфицированных НР. Материал и методы. Наблюдалось 50 пациентов, инфицированных НР. Всем пациентам была назначена тройная терапия с двойной дозировкой ингибитора протонной помпы (ИПП), усиленная препаратами висмута (кларитромицин 500 мг, амоксициллин 1000 мг, висмута трикалия дицитрат 240 мг, эзомепразол 40 мг/рабепразол 40 мг). Все препараты принимались 2 раза в сутки на протяжении 14 дней. В зависимости от применяемого ИПП пациенты были рандомизированы на две группы: получавшие эзомепразол 40 мг (группа 1) или рабепразол 40 мг (группа 2). Генотип цитохрома Р450 2C19 определялся методом ПЦР (тест-система Seeplex® CYP2C19 Genotyping Set.) Результаты. Генетический полиморфизм цитохрома Р450 2C19 у пациентов, инфицированных НР, в Крыму представлен генотипами *1/*1 — 69,9% и *1/*2 — 30,1%. Частота эрадикации при использовании схем с эзомепразолом и рабепразолом составила 87,8% (95% доверительный интервал: 81,2–89,0%) и 85,7% (95% доверительный интервал 79,5–88,4%) соответственно. Частота эрадикации при использовании схем с эзомепразолом и рабепразолом достоверно не различалась у пациентов с генотипами *1/*1 (p = 0,999) и *1/*2 (p = 0,286). На 5-е сутки средний показатель внутрижелудочного pH в группе рабепразола был выше, чем в группе эзомепразола (5,7 против 5,4 соответственно), но не достиг статистической разницы (p = 0,308). Заключение. Использованные схемы ЭТ были одинаково эффективны в каждой группе, независимо от генотипа CYP2C19, а профили внутрижелудочного pH сопоставимы. </p></abstract><trans-abstract xml:lang="en"><p>Relevance. Infection with Helicobacter pylori (НР), a class 1 carcinogen for gastric cancer development, is steadily increasing in the world population and reaches 50%. Currently, eradication therapy (ET) is considered the most relevant strategy for the prevention of gastric cancer. Due to the low eradication rates when using a triple regimen based on clarithromycin, the addition of bismuth salts and the use of double doses of proton pump inhibitors are recommended. Objective. To evaluate the effectiveness of double doses of esomeprazole and rabeprazole in ET in patients with different genotypes of cytochrome P450 2C19, infected with НР. Material and methods. 50 patients infected with Helicobacter pylori were recruited. All patients were prescribed triple therapy with a double dose of proton pump inhibitor (PPI) enhanced with bismuth preparations (clarithromycin 500 mg, amoxicillin 1000 mg, bismuth tripotassium dicitrate 240 mg, esomeprazole 40 mg/rabeprazole 40 mg.) All drugs were taken 2 times a day for 14 days. Depending on the PPI used, patients were randomized into two groups: esomeprazole 40 mg (group 1) and rabeprazole 40 mg (group 2).The genotype of cytochrome P450 2C19 was determined by PCR (test system Seeplex® CYP2C19 Genotyping Set.) Results. Genetic polymorphism of cytochrome P450 2C19 in patients infected with H. pylori in Crimea is represented by genotypes *1/*1 — 69.9% and *1/*2 — 30.1%. The eradication rate using regimens with esomeprazole and rabeprazole was 87,8% (95% confidence interval: 81.2–89.0%) and 85,7% (79.5–88.4%), respectively. The eradication rate using regimens with esomeprazole and rabeprazole did not differ significantly in patients with genotypes *1/*1 (p = 0.999) and *1/*2 (p = 0.286). On day 5, the mean intragastric pH was higher in the rabeprazole group compared with the esomeprazole group (5,7 vs. 5,4), but did not achieve a statistical difference (p = 0.308). Conclusion: The ET regimens used were equally effective in each group, regardless of the CYP2C19 genotype, and the intragastric pH profiles were comparable. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>эрадикационная терапия</kwd><kwd>Helicobacter pylori</kwd><kwd>CYP2C19</kwd></kwd-group><kwd-group xml:lang="en"><kwd>eradication therapy</kwd><kwd>Helicobacter pylori</kwd><kwd>CYP2C19</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">Бордин Д.С.
