Previous systematic reviews have demonstrated the possibility to use probiotics to prevent ARI in children. The prophylactic efficacy of the <italic>B. bifidum</italic> 1 strain in patients with recurrent ARI has not been investigated specifically against the background of concomitant gastrointestinal disorders, which may affect the effectiveness of probiotic therapy.</p><p><bold>Aim:</bold> To evaluate the effectiveness and safety of the sorbed probiotic <italic>B. bifidum</italic> 1 for prevention of ARI in children of 7 to 11 years of age with functional intestinal disorders or gastritis / gastroduodenitis.</p><p><bold>Materials and methods</bold>: This prospective, randomized, open-label study was completed by 44 children divided into two parallel groups: with and without administration of the sorbed <italic>B. bifidum</italic> 1 at 5 × 10<sup>7</sup> CFU three times daily for 21 days as a component of a comprehensive sanatorium treatment for recurrent ARI. The children were followed up for three months after the end of the treatment in a winter season, with assessment of frequency, severity and duration of ARI episodes.</p><p><bold>Results:</bold> The use of <italic>B. bifidum</italic> 1 in children of 7–11 years old with functional and chronic gastrointestinal disorders reduced the incidence of upper respiratory tract infections (relative risk reduction 0.48, 95% confidence interval 0.15–0.68) and mean duration of respiratory diseases by 2.26 days (95% confidence interval 0.23–4.27). It also reduced fever, frequency of cases with cough and the need in antibiotic therapy. The efficacy was related mainly to a decrease in the number of children with more than one ARI episode during the three months of the winter season.</p><p><bold>Conclusion:</bold> The results of probiotics use should be evaluated with consideration of underlying disease, which can more clearly indicate the size of their effect. The use of probiotics for prevention of infectious diseases, including respiratory infections, in children with functional and chronic gastrointestinal disorders can be promising in reduction of the overall morbidity and requires further studies.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Актуальность.</bold> Острые респираторные заболевания (ОРЗ) признаны существенной проблемой здравоохранения во всем мире в связи с высокой заболеваемостью и отсутствием специфической профилактики для большинства инфекций. В  систематических обзорах показана возможность применения пробиотиков для профилактики ОРЗ у детей. Вместе с тем отдельно не исследовалась профилактическая эффективность штамма <italic>B. bifidum</italic> 1 у пациентов с повторными ОРЗ на фоне сопутствующей гастроинтестинальной патологии, которая может влиять на эффективность пробиотической терапии.</p><p><bold>Цель </bold>– оценить эффективность и безопасность применения сорбированного пробиотика <italic>B.  bifidum </italic> 1 для профилактики ОРЗ у детей 7–11 лет с функциональными кишечными расстройствами или гастритом / гастродуоденитом.</p><p><bold>Материал и методы.</bold> Проведено проспективное рандомизированное открытое исследование. Исследование завершили 44 ребенка, распределенных на две параллельные группы – получавших и не получавших сорбированные <italic>B. bifidum</italic> 1 в течение 21 дня по 5 × 10<sup>7</sup> КОЕ трижды в день в составе комплексного санаторного лечения, назначенного по поводу повторных ОРЗ. Дети наблюдались в течение 3 месяцев после окончания лечения в  зимнем сезоне с  оценкой частоты, тяжести и  продолжительности эпизодов ОРЗ.</p><p><bold>Результаты.</bold> Использование <italic>B. bifidum</italic> 1 у детей 7–11 лет с функциональной и хронической патологией желудочно-кишечного тракта сокращало частоту инфекций верхних дыхательных путей (сокращение относительного риска 0,48; 95% доверительный интервал 0,15–0,68), среднюю продолжительность респираторных заболеваний на 2,26 дня (95% доверительный интервал 0,23–4,27), уменьшало величину лихорадки, частоту случаев с кашлем и назначения антибактериальной терапии. Эффективность получена за счет уменьшения количества детей, болевших ОРЗ более 1 раза в течение 3 месяцев зимнего сезона.</p><p><bold>Заключение</bold>. Pезультаты применения пробиотиков целесообразно оценивать с  учетом фоновых заболеваний и состояний пациентов, что может более четко обозначить размер эффекта препарата. Применение пробиотиков для профилактики инфекционных заболеваний, включая респираторные инфекции, у  детей с  функциональной и  хронической патологией желудочно-кишечного тракта может быть перспективным направлением снижения общей заболеваемости и заслуживает дальнейших исследований.</p></trans-abstract><kwd-group xml:lang="en"><kwd>children</kwd><kwd>probiotics</kwd><kwd>sorbed on activated carbon B. bifidum 1</kwd><kwd>prophylaxis</kwd><kwd>recurrent acute respiratory infections</kwd><kwd>functional intestinal disorders</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>дети</kwd><kwd>пробиотики</kwd><kwd>B. bifidum 1, сорбированные на активированном угле</kwd><kwd>профилактика</kwd><kwd>повторные острые респираторные заболевания</kwd><kwd>функциональные кишечные расстройства</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
