It is noteworthy to mention that a study by Wang M. et al. identified COVID-19 patients with liver injury to have high serum levels of ferritin, high-sensitivity CRP, procalcitonin, interleukin-2 receptor (IL-2R), tumor necrosis factor-α (TNF-α), erythrocyte sedimentation rate, gamma-glutamyl transferase (γ-GT), and lactate dehydrogenase (LDH) [64,66]. This evidence concerns the gene TNF and COVID-19.
