Possible role of anti-IL17 drugs in the management of COVID-19: Our own experience and literature review

Abstract

Coronavirus infection COVID-19 is an acute respiratory viral disease caused by a novel beta-coronavirus SARS-CoV-2. In 81 % of cases, mortality in COVID-19 patients is associated with the development of acute respiratory distress syndrome (ARDS). Another critical challenge associated with COVID-19 is the development of a cytokine storm, which is an uncontrolled release of proinflammatory mediators due to the excessive activation of immune system. Cytokine storm is another cause of high mortality because of COVID-19, as it leads to multiple organ failure, ARDS and disseminated intravascular coagulation (DIC). Thus, the management of cytokine storm and ARDS in COVID-19 patients is an urgent issue for the medical society. Recent research assessed the potential role of interleukin(IL)-17 in the pathogenesis of cytokine storm and ARDS in COVID-19 patients. Some authors also pointed to using anti-IL17 medications in the management of patients with severe COVID-19. The present article gives a literature review on the possible role of IL-17 in COVID-19 pathogenesis and our personal experience of anti-IL17 prescription for patients with severe course of COVID-19.
