Severe COVID-19 goes along with significantly elevated levels of pro-inflammatory cytokines like IL-6, IL-8, IL-10, IL-2R, and TNF-α produced by a dysregulated immune system, leading to a pathophysiological phenomenon called “cytokine storm”, which is characterized by a rapid inflammatory cascade, resulting in hypercoagulability, tissue damage and multiorgan failure [6,9]. Here, IL6 is linked to COVID-19.
