Preliminary data obtained in studies of properties of recombinant interferon gamma (IFN-γ) that involved patients with community-acquired pneumonia (including bacterial), acute respiratory viral infection (ARVI), influenza and new coronavirus infection have shown promising results.</p><p>The <bold>purpose</bold> of the study was to assess the effect of subcutaneous administration of IFN-γ in patients with viral pneumonia on the changes of vital signs and the duration of hospital stay.</p><p><bold>Material and methods</bold>. An open-label, randomized, low-interventional study included patients with moderate new coronavirus infection COVID-19 over 18 years of age of both sexes. IFN-γ 500,000 IU was administered s/c, daily, once a day, during 5 days.</p><p><bold>Results.</bold> IFN-y in addition to complex therapy of the disease resulted in more favorable changes in the stabilization of vital signs, as well as in reduced length of fever and hospital stay by 2 days what allows suggesting a positive effect of this substance on the recovery processes in patients with moderate COVID-19. Special emphasis should be made to the fact that patients who received recombinant IFN- γ experienced no progression of respiratory failure and required no transfer to intensive care unit.</p><p><bold>Discussion.</bold> This study confirms earlier obtained data on the positive effect of IFN-y on the rate of clinical stabilization and recovery of patients with community-acquired pneumonia and viral infections. Presented results are limited to a small number of patients; further study of drug properties in post-marketing studies is required.</p><p><bold>Conclusion.</bold> Progress in the treatment of patients with moderate COVID-19 by adding recombinant IFN-γ to the complex therapy may reasonably expand the range of existing treatment options for this infection.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение. </bold>Интерфероны вырабатываются в ответ на внедрение патогена в клетку и отвечают за правильное формирование иммунного ответа. Предварительные исследования с участием пациентов с внебольничной пневмонией (в т.ч. бактериального генеза), острой респираторной вирусной инфекцией (ОРВИ), гриппом и новой коронавирусной инфекцией COVID-19 по изучению свойств рекомбинантного интерферона гамма (ИФН-γ) показали обнадёживающие результаты.</p><p><bold>Цель </bold>данной работы - оценка влияния ИФН-γ при подкожном введении у лиц с вирусной пневмонией на динамику жизненно важных показателей и длительность госпитализации.</p><p><bold>Материал и методы</bold>. В открытое рандомизированное малоинтервенционное исследование были включены пациенты старше 18 лет обоих полов с новой коронавирусной инфекцией среднетяжёлого течения. Препарат ИФН-γ назначался по 500 000 МЕ подкожно 1 раз в сутки ежедневно на протяжении 5 дней.</p><p><bold>Результаты.</bold> Установлена более благоприятная динамика стабилизации жизненно важных показателей в сочетании с сокращением длительности лихорадки и продолжительности госпитализации на 2 сут при применении ИФН-γ в дополнение к комплексной терапии, что позволяет предположить позитивное влияние этого вещества на процессы восстановления больных со среднетяжёлой степенью COVID-19. Особого внимания заслуживает тот факт, что получавшие рекомбинантный ИФН-γ не имели прогрессирования дыхательной недостаточности и не требовали перевода в отделение интенсивной терапии (ОРИТ). Обсуждение. Представленная работа подтверждает полученные ранее данные о положительном влиянии ИФН-γ на скорость клинической стабилизации и выздоровления лиц с внебольничными пневмониями и вирусными инфекциями. Результаты настоящего исследования ограничены небольшим количеством участников и требуют дальнейшего изучения свойств препарата в рамках пострегистрационных исследований.</p><p><bold>Заключение.</bold> Прогресс в лечении больных среднетяжёлой формой COVID-19 путём дополнения комплексной терапии рекомбинантным ИФН-y может обоснованно расширить ряд существующих методов лечения этой инфекции.</p></trans-abstract><kwd-group xml:lang="en"><kwd>interferon gamma</kwd><kwd>COVID-19</kwd><kwd>coronavirus infections</kwd><kwd>viral pneumonia</kwd><kwd>vital signs</kwd><kwd>duration of hospital stay</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>интерферон гамма</kwd><kwd>COVID-19</kwd><kwd>новая коронавирусная инфекция</kwd><kwd>вирусная пневмония</kwd><kwd>жизненно важные показатели</kwd><kwd>длительность госпитализации</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The study had no sponsorship</funding-statement><funding-statement xml:lang="ru">Работа не имела спонсорской поддержки</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.	https://clinicaltrials.gov/ct2/results?cond=COVID-19%2C+SARS-CoV-2&amp;term=IFN&amp;cntry=&amp;state=&amp;city=&amp;dist= (accessed December 16, 2020).</mixed-citation></ref><ref id="B2"><label>2.</label><mixed-citation>2.
