Coagulation and endothelial markers D-dimer, E-selectin (E-Sel), Intercellular Adhesion Molecule-1 (ICAM-1), and Vascular Cell Adhesion Molecule-1 (VCAM-1), together with key inflammatory cytokines (IL-6, IL-8, TNF-α, IFN-γ, IL-1β), will be assessed at three and twelve months postSARS-CoV-2 infection. Here, VCAM1 is linked to COVID-19.
