There were enrolled 60 subjects (males and females) aged 18 to 75 years, who received a 10-day-long therapy in accordance with the “Prevention, Diagnostics and Treatment of new coronavirus infection (COVID-19). Temporary Guidelines. Version 11”. Inclusion criteria were as follows: males and females aged 18 to 75 years, with positive PCR SARS-CoV-2 result, body temperature ≥ 38.5°C for 3 days; presence of typical CT scan confirmed coronavirus pneumonia; patients’ consent to hospitalization and participation in the study. Patients included in the study were randomized into 2 groups per 30 subjects. In control group, subjects received routine treatment and placebo; in comparison group — routine treatment combined with the preparation Glucaferon. By the end of treatment, all patients in both groups showed positive dynamics. An X-ray examination revealed significantly decreased intensity and size of pre-identified “ground glass” areas of compaction in lung tissue. Residual effects manifested as reticular changes, low-intensity areas of compaction without clear contours. Blood oxygen saturation was also restored to normal levels. Anosmia in both groups was noted by no more than 6% of patients. Patients’ assessment of the intensity of the two most severe symptoms, cough and shortness of breath, using visual analogue scales, also revealed positive dynamics. Despite that the majority of study patients had prerequisites for a complicated COVID-19 course as well as critical levels of laboratory parameters detected in some patients upon admission, the use of Glucaferon caused no negative or adverse reactions, nor stimulated an immune response, while the preparation Glucaferon demonstrated a clinically significant anti-inflammatory effect.</p></abstract><trans-abstract xml:lang="ru"><p>В данной статье представлены результаты ограниченного, слепого, плацебо-контролируемого исследования по изучению влияния комплексного препарата Глюкаферон состоящего преимуществено из бета-глюканов, получаемых из пищевых грибов Вешенка обыкновенная, и биологически активных веществ с известной антиоксидантной и противовоспалительной активностью, на эффективность стандартной терапии среднетяжелой формы острой инфекции, вызванной вирусом SARS-CoV-2. В исследование было включено 60 человек, мужчины и женщины, в возрасте от 18 до 75 лет, получавших стандартную терапию, регламентированную 11-й версией временных методических рекомендаций по профилактике, диагностике и лечении новой коронавирусной инфекции (COVID-19), в течение 10 дней. Критерии включения пациентов в исследование: мужчины и женщины в возрасте от 18 до 75 лет, с положительным ПЦР-тестом на SARS-CoV-2, температурой тела ≥ 38,5°C в течение 3 дней; наличие типичной коронавирусной пневмонии подтвержденной КТ; согласие пациентов на госпитализацию и участие в исследовании. Пациенты, включенные в исследование, были рандомизированы на 2 группы по 30 человек. Контрольная группа получала стандартное лечение и плацебо, в испытуемой группе стандартное лечение дополнялось препаратом Глюкаферон. К концу лечения в обеих группах, независимо от схемы лечения, у всех пациентов отмечена положительная динамика. При рентгенологическом обследовании определялось значительное уменьшение интенсивности и размеров ранее выявляемых зон уплотнения легочной ткани по типу «матового стекла». Остаточные явления проявлялись в виде ретикулярных изменений, слабоинтенсивных зон уплотнения без четких контуров. Насыщение крови кислородом также восстанавливалось до нормальных показателей. Явления аносмии в обеих группах отмечали не более 6% пациентов. Оценка пациентами с помощью визуальных аналоговых шкал интенсивности двух наиболее тяжело переносимых симптомов: кашля и одышки также свидетельствовала о положительной динамике. Несмотря на то что у большинства пациентов, включенных в данное исследование, имелись предпосылки для осложненного течения COVID-19, а также выявленные при поступлении в стационар у некоторых пациентов критические уровни лабораторных показателей, применение Глюкаферона не вызвало никаких отрицательных и побочных реакций, не стимулировало иммунного ответа, при этом препарат продемонстрировал клинически значимое противовоспалительное действие.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Glucaferon</kwd><kwd>coronavirus</kwd><kwd>beta-D-glucan</kwd><kwd>cytokine storm syndrome</kwd><kwd>oyster mushroom</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>Глюкаферон</kwd><kwd>коронавирус</kwd><kwd>бета-D-глюкан</kwd><kwd>цитокиновый шторм</kwd><kwd>Вешенка обыкновенная</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Боровиков В.П.
