Abstract

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is an infectious disease that causes severe coronavirus disease 2019 (COVID-19) and its complications, this appears to be related to an increase in the release of pro-inflammatory cytokines, described as “the cytokine storm.” SARS-CoV-2 by binding to its receptor angiotensin converting enzyme 2 triggers an imbalance in the renin angiotensin aldosterone system, inducing an increase in angiotensin (Ang) 2 and a decrease in Ang 1-7 levels. The cytokine storm is the major cause of respiratory distress syndrome from which suffers patients with severe forms of COVID- 19 as well as multi organ failure (lung, heart, kidney, liver, and brain). To resist this cytokine storm, interleukin-1 and 6 inhibitors, tumor necrosis factor inhibitors, interferon inhibitors, and steroid immunomodulators have been used. This review article summarizes COVID-19 patients, disease manifestations, cytokine storm characteristics, general clinical signs symptoms, and targeting the cytokine storm with cytokine inhibitors.

Keywords: SARS-CoV-2. COVID-19. Cytokine storm. Inhibitors.
