Increased ferritin, decreased platelet counts, elevated procalcitonin, CRP, and ESR in the severe stage of COVID-19 are also consistent with this syndrome, and for this reason, steroids, IVIG, specific cytokine blockade (e.g., baricitinib, anakinra, or tacilizumab), and JAK inhibition can be effective for these patients [74, 75]. This evidence concerns the gene CRP and COVID-19.
