IL6 and COVID-19: Table 2 highlights recent studies examining these and other rarer, less characterized COVID-19 complications. Obese patients are known to have higher levels of inflammatory and thrombotic markers including C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), peripheral venous blood lymphocyte levels, IL-6 and D-dimer. These effects are exacerbated in the setting of COVID-19, leading to severe disease and death [13,14,48,49].
