CRP and COVID-19: In the para clinical work up, an inflammatory syndrome (white blood cells: 19,000/mm3, C-reactive protein (CRP): 268 mg/l, procalcitonin: 2.9 mg/l, fibrinogen: 8.7 g/l, lactate dehydrogenase: 1352 g/mol with ferretinemia: 2350 mg/l) was found, and because of the pandemic context, a thoracic computed tomography (CT) scan was performed; showing diffuse patchy ground-glass like opacities suggesting COVID-19 pneumonia with severe involvement (75%), a COVID-19 polymerase chain reaction (PCR) test was positive, with D-dimers: 8.40 ùg/l.
