Актуальность поиска новых средств лечения ОРДС связана с пандемией COVID-19, для которого эти факторы обуславливают тяжелое течение болезни. Нами впервые показано, что введение лейтрагина в сочетанном режиме, внутримышечная инъекция плюс ингаляция, приводило к статистически значимому повышению выживаемости животных как в режиме лечения (после индукции ОРДС), так и при профилактическом курсовом введении (до индукции ОРДС). Лейтрагин многократно снизил коэффициенты риска гибели животных с ОРДС относительно контроля. Обнаруженное нами профилактическое действие лейтрагина заслуживает особого внимания, т. к. оно позволяет предотвратить возникновение заболевания, переход легкой стадии поражения легких в тяжелую, а также уменьшить риск развития ОРДС и снизить риск летального исхода. Таким образом, использование лейтрагина может быть новым эффективным подходом к лечению и профилактике респираторных заболеваний, сопровождающихся «цитокиновым штормом» и ОРДС, в т. ч. коронавирусной инфекции COVID-19.</p></abstract><trans-abstract xml:lang="en"><p>This study aims to investigate effects of leutragin, an opioid peptide analogue of endogenous dynorphin 1-6, on animal survival in an experimental model of “cytokine storm” and fatal acute respiratory distress syndrome (ARDS) in C57Bl/6Y mice under different administration regimens. The aforementioned factors cause a severe course of COVID-19, which explains the current interest in seeking new treatments for ARDS. It was shown that both the prophylactic (before ARDS induction) and therapeutic (after ARDS induction) administration of leutragin in a combined mode — intramuscular injection plus inhalation leads to a statistically signiﬁcant increase in the survival rate of animals. Compared to the control, leutragin signiﬁcantly reduced the risk of death in animals with ARDS. The discovered prophylactic effect of leutragin deserves special attention due to its potential in preventing the onset of the disease and impeding the development of severe lung damage, thus reducing the risk of ARDS and fatal outcomes. Thus, the use of leutragin can be seen as a new effective approach to the treatment and prevention of respiratory diseases associated with a “cytokine storm” and ARDS, including the coronavirus infection COVID-19.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>лейтрагин</kwd><kwd>острый респираторный дистресс-синдром</kwd><kwd>мыши линии C57Bl/6Y</kwd><kwd>«цитокиновый шторм»</kwd><kwd>выживаемость</kwd><kwd>лечение</kwd><kwd>профилактика</kwd><kwd>COVID-19</kwd></kwd-group><kwd-group xml:lang="en"><kwd>leutragin</kwd><kwd>acute respiratory distress syndrome</kwd><kwd>C57Bl/6Y mice</kwd><kwd>“cytokine storm”</kwd><kwd>survival</kwd><kwd>treatment</kwd><kwd>prophylaxis</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">Каркищенко Н.Н.
