Markers of hyperinflammation, degree of lymphopaenia, neutrophil levels, TNF-α, INR levels, and proinflammatory cytokines (interleukin (IL)-6 and IL-8) were significantly increased in COVID-19 patients compared to healthy controls (p < 0.05, 95% CI) (Figure 3). This evidence concerns the gene CXCL8 and COVID-19.
