В этой связи в качестве инструмента широко применяются синтетические пептиды. Представителем этой  группы является синтетический аналог регуляторных пептидов вилочковой железы Тимоген, который применяется в России уже более 20 лет для лечения острых и хронических инфекционных заболеваний.</p><sec><title>Цель исследования</title><p>Цель исследования. Оценить действие препарата Тимоген спрей на индуцированные показатели иммунной системы при профилактическом применении у здоровых добровольцев.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. 20 здоровых добровольцев получали препарат Тимоген спрей (АО «МБНПК «Цитомед», Россия) в дозе 25 мкг 2 раза в сутки в  течение 10  дней. Иммунологические показатели оценивали в динамике: до начала терапии, на 6-й и 11-й дни приёма и через 14 дней после окончания курса. Клиническое наблюдение осуществляли с 1-го по 11-й дни, регистрацию нежелательных явлений – в течение всего периода исследования (24 дня).</p></sec><sec><title>Результаты исследования</title><p>Результаты исследования. Выявлено статистически значимое увеличение вирус-индуцированной продукции α-интерферона культурой клеток крови к 11-му дню приёма Тимогена. Этот эффект сохранялся ещё в течение 14  дней после окончания курса. Статистически значимых различий в динамике бактерицидной и фагоцитарной активности нейтрофилов, сывороточного α- и γ-интерферона не получено.</p></sec><sec><title>Заключение</title><p>Заключение. Использование препарата Тимоген спрей в дозе 25 мкг в течение 10 дней было безопасным, не влияло на морфофункциональное состояние иммунной системы, но способствовало статистически значимому увеличению продукции α-интерферона в ответ на индуцирующее воздействие вирусного патогена in  vitro. Это позволяет рекомендовать препарат для  профилактического применения в период подъёма заболеваемости острыми респираторными инфекциями.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. During the ongoing COVID-19 pandemic and in the season of rising incidence of other respiratory infections, it is relevant to use preventive measures of  non-specific prophylaxis. Synthetic peptides are widely considered as a tool. The representative of this group is the synthetic analogue of thymus regulatory peptides Thymogen, which has been used in Russia for more than 20 years in the treatment of acute and chronic infection diseases.</p></sec><sec><title>The aim of the study</title><p>The aim of the study. To evaluate the effect of Thymogen, a dosed nasal spray, on induced parameters of the immune system during prophylactic use in healthy volunteers.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Twenty healthy volunteers received Thymogen nasal dosed spray (JSC  “Cytomed”, Russia) at a dose of 25  μg twice a day for 10  days. A  comparative assessment of  immunological parameters was carried out in dynamics: before the start of therapy, on days 6 and 11 of taking the drug and 14 days after the end of the course. Clinical observation was carried out from day 1 to day 11, registration of adverse events – the entire period of the study for 24 days. The first day was considered the day the drug was started.</p></sec><sec><title>Results</title><p>Results. In the course of the work, according to the data of immunological examination, a statistically significant increase in the virus-induced production of interferon alpha (INF-α) by a culture of peripheral blood cells was revealed. The growth rate was recorded on day  11 of taking Thymogen and persisted for 14  days after  the  end  of  the  course. Significant differences in the dynamics of bactericidal and phagocytic activity of neutrophils, serum α- and γ-interferon were not obtained.</p></sec><sec><title>Conclusion</title><p>Conclusion. The use of Thymogen spray at a dose of 25 μg for 10 days was safe and contributed to a significant induction of interferon-alpha in response to exposure to a viral pathogen, which allows us to recommend the drug for prophylactic use during the period of rising incidence of acute respiratory diseases.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>альфа-глутамил-триптофан</kwd><kwd>альфа-интерферон</kwd><kwd>вирусные инфекции</kwd><kwd>здоровые добровольцы</kwd><kwd>неспецифическая профилактика</kwd><kwd>факторы врожденного иммунитета</kwd></kwd-group><kwd-group xml:lang="en"><kwd>alfa-glutamyl-tryptophan</kwd><kwd>interferon-alpha</kwd><kwd>viral infections</kwd><kwd>healthy volunteers</kwd><kwd>non-specific prophylaxis</kwd><kwd>factors of innate immunity</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">Biron CA.
