Increased values for the white blood cell count, C-reactive protein (CRP) level [8], procalcitonin level [70], presepsin level [71], C5b-9 and C5a levels [44], and levels of inflammatory cytokines, such as tumor necrosis factor α, interleukin-1, interleukin-2, interleukin-6, interleukin-10 and interferon γ, were reported in patients with severe COVID-19; elevation in these inflammatory factors can lead to cytokine storm [72]. The gene discussed is CRP; the disease is COVID-19.
