Проведено проспективное рандомизированное сравнительное клиническое исследование. Эрадикационную терапию прошли 208 пациентов (147 мужчин, 61 женщина; средний возраст — 48,1 ± 14,5 года) с язвенной болезнью двенадцатиперстной кишки, ассоциированной с Helicobacter pylori (H. pylori). Диагностика H. pylori в слизистой оболочке желудка осуществлялась морфологическим методом и быстрым уреазным тестом до лечения и через 6-8 недель после окончания лечения и отмены всех лекарственных средств. Пациентов разделили на три группы согласно протоколам лечения: омепразол 0,04 г/сут, кларитромицин 1 г/сут, амоксициллин 2 г/сут (ОКА; n = 103); омепразол 0,04 г/сут, кларитромицин 1 г/сут, амоксициллин 2 г/сут + ГМДП 0,001 г/сут (ОКАЛ1; n = 61) или 0,01 г/сутки (ОКАЛ10; n = 44) в течение 10 дней. Обнаружение РНК SARS-CoV-2 методом ПЦР осуществлялось с апреля 2020 по апрель 2022 г. Полнота отслеживания составила 96,6 %.</p></sec><sec><title>Результаты</title><p>Результаты. Частота эрадикации H. pylori в зависимости от назначенного лечения (ITT) и фактически полученного лечения (PP): ОКА — 79 % (95 % ДИ: 71-87) и 83 % (95 % ДИ: 75-91), ОКАЛ1 — 95 % (95 % ДИ: 88-100) и 97 % (95 % ДИ: 92-100), ОКАЛ10 — 96 % (95 % ДИ: 89-100) и 98 % (95 % ДИ: 93-100) соответственно. Частота нежелательных реакций в зависимости от ITT и PP: ОКА — 24 % (95 % ДИ: 16-33) и 26 % (95 % ДИ: 17-35); ОКАЛ1 — 2 % (95 % ДИ: 0,01-8) и 2 % (95 % ДИ: 0,01-8); ОКАЛ10 — 2 % (95 % ДИ: 0,01-7) и 2 % (95 % ДИ: 0,01-7). Заболеваемость инфекцией COVID-19 в зависимости от ITT и PP: ОКА — 9 % (95 % ДИ: 3-14) и 9 % (95 % ДИ: 3-15); ОКАЛ1 + ОКАЛ10 — 1 % (95 % ДИ: 0,003-1,9) и 1 % (95 % ДИ: 0,001-2,9) соответственно.</p></sec><sec><title>Выводы</title><p>Выводы. У инфицированных H. pylori пациентов ГМДП (иммуномодулятор на основе L. bulgaricus) в дозе 1-10 мг/сут при проведении 10-дневной тройной эрадикационной терапии позволяет достоверно (p &lt; 0,05) увеличить частоту эрадикации H. pylori и уменьшить частоту нежелательных реакций по сравнению с 10-дневным протоколом без адъювантной терапии ГМДП. Отмечено достоверное (p &lt; 0,05) снижение заболеваемости инфекцией COVID-19 после проведения эрадикационной терапии H. pylori c приемом ГМДП.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim: evaluation of the incidence of COVID-19 infection after three-component H. pylori eradication therapy while taking N-acetyl-glucosaminyl-N-acetyl-muramyl dipeptide (GMDP).</p></sec><sec><title>Materials and methods</title><p>Materials and methods. A prospective randomized comparative clinical study was carried out. The study included 208 patients (147 men, 61 women; mean age — 48.1 ± 14.5 years) with duodenal ulcer associated with Helicobacter pylori (H. pylori) who underwent eradication therapy. H. pylori in the gastric mucosa was detected by a morphological method and a rapid urease test before treatment and 6-8 weeks after the end of treatment and the withdrawal of all drugs. Patients were divided into three groups according to treatment protocols: omeprazole 0.04 g/day, clarithromycin 1 g/day, amoxicillin 2 g/day (OСA; n = 103); omeprazole 0.04 g/day, clarithromycin 1 g/day, amoxicillin 2 g/day + GMDP 0.001 g/day (OCAL1; n = 61) or 0.01 g/day (OCAL10; n = 44) for 10 days. Detection of SARS-CoV-2 RNA by PCR was carried out from April 2020 to April 2022. Tracking completeness was 96.6 %.</p></sec><sec><title>Results</title><p>Results. The frequency of H. pylori eradication depending on “intention to treat” (ITT) and “per protocol” (PP): OCA — 79 % (95 % CI: 71-87) and 83 % (95 % CI: 75-91); OCAL1 — 95 % (95 % CI: 88-100) and 97 % (95 % CI: 92-100); OCAL10 — 96 % (95 % CI: 89-100) and 98 % (95 % CI: 93-100) respectively. The frequency of adverse reactions depending on ITT and PP: OCA — 24 % (95 % CI: 16-33) and 26 % (95 % CI: 17-35); OCAL1 — 2 % (95 % CI: 0.01-8) and 2 % (95 % CI: 0.01-8); OCAL10 — 2 % (95 % CI: 0.01-7) and 2 % (95 % CI: 0.01-7). The incidence of COVID-19 infection depending on ITT and PP: OCA — 9 % (95 % CI: 3-14) and 9 % (95 % CI: 3-15); OCAL1 + OCAL10 — 1 % (95 % CI: 0.003-1.9) and 1 % (95 % CI: 0.001-2.9), respectively.</p></sec><sec><title>Conclusions</title><p>Conclusions. In H. pylori-infected patients, GMDP (an immunomodulator based on L. bulgaricus) at a dose of 1-10 mg/day, during a 10-day triple eradication therapy, allows a significant (p &lt; 0.05) increase in the frequency of H. pylori eradication and reduce the incidence of adverse reactions compared with a 10-day protocol without adjuvant therapy with GMDP. There was a significant (p &lt; 0.05) decrease in the incidence of COVID-19 infection after H. pylori eradication therapy with GMDP.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Helicobacter pylori</kwd><kwd>язва</kwd><kwd>двенадцатиперстная кишка</kwd><kwd>тройная эрадикационная терапия</kwd><kwd>N-ацетилглюкозаминил-N-ацетилмурамилдипептид</kwd><kwd>COVID-19</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Helicobacter pylori</kwd><kwd>duodenal ulcer</kwd><kwd>triple eradication therapy</kwd><kwd>N-acetyl-glucosaminyl-N-acetyl-muramyl dipeptide</kwd><kwd>COVID-19</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">Marshall B.J., Warren J.R.
