Home Care Follow up determine the point of inversion of IL-6 levels in relation to C-Reactive Protein as the cytokine storm marker in COVID-19

The IL-6 has been used for the characterization of the cytokine storm induced by SARS-CoV-2, but so far, no one has found out when and in whom the cytokine storm develops. Our study demonstrates how early and longitudinal clinical-based monitoring and dosing of five markers (C-reactive protein, IL-6, fibrinogen, ferritin and D-dimer) helped to identify who had developed the cytokine storm. The peak of IL-6 in pg/mL proportionally higher than the peak of CRP in mg/L was sufficient to define the timing of the evolution of cytokine storm syndrome. The administration of antibiotic therapy, anticoagulant therapy and pulse therapy resolved the infection and prevented the progressive deterioration of the lung function of the patients with potential for development of severe COVID-19.
