In contrast, patients with fatal COVID-19 (Figure 5B) displayed a negative correlation between leukocytes and lymphocytes, and their inflammatory markers increased with markers of organ failure (liver enzymes, amylase, GGT, urea, and creatinine) and cytotoxic cellular immunity (activated CD38+ HLA-DR+ CD8 T cells) instead. The gene discussed is CD8A; the disease is COVID-19.
