In consistent with this, a recent clinical study reported that compared to COVID-19 patients without diabetes, people with diabetes had activated inflammatory response (manifested as elevated levels of neutrophils, serum ferritin, IL-6, C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR)) and suppressed immunity (manifested as markedly decreased levels of lymphocytes) [9]. The gene discussed is CRP; the disease is diabetes mellitus.
