Laboratory results showed lymphopenia of 940/μl (normal 1.100–3.200), increased D-dimer with 0.87 μg/ml (< 0.5), fibrinogen 574 mg/dl (170–410), C-reactive protein (CRP) 29.5 mg/dl (≤ 0.5), IL-6 100 ng/l (0–4), LDH with 479 U/l (≤ 250) creatine kinase 280 U/l (≤ 190), and ferritin 113 μg/dl (3–30) (see also supplementary Fig. 1). Here, IL6 is linked to lymphopenia.
