Clinical Trial Summary

Severe acute respiratory syndrome (SARS)-like coronavirus 2 (Sars-CoV-2) pandemia is considered to be the current major global health issue. With no specific treatment or vaccine known to be licensed, empowering the immune system to overcome the inflammatory status associated with the late stages of the disease, particularly by anti-inflammatory nutrients, is of great concern. Effective in reducing both the morbidity and mortality of respiratory infections, including measles, vitamin A and its derivatives are reported to enhance the immune system and/or antibody response to virus vaccinations in children, particularly those with vitamin insufficiency. Retinoids are, therefore, proposed as an adjunct therapy in the treatment of COVID-19. The study is aimed to investigate the effects of vitamin A supplementation on disease improvement in pediatric and adolescent patients with either moderate or severe COVID-19 disease.
