Chen et al., who retrospectively evaluated 99 patients with laboratory-confirmed COVID-19 infection, reported lymphopenia in 35% of cases, as well as increased levels of neutrophils, IL6, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) in 35%, 52%, 85%, and 86% of cases, respectively (6). This evidence concerns the gene CRP and lymphopenia.
