Abstract

The aim of this study was to assess the key laboratory features displayed by coronavirus disease 2019 (COVID-19) inpatients which associated with mild, moderate, severe and fatal course of the disease and, through longitudinal follow-up, to understand the dynamics of COVID-19 pathophysiology. All SARS-CoV-2 positive patients admitted to the University Hospital in Motol between March and June 2020 were included in this study. Severe course of COVID-19 was associated with elevation of proinflammatory markers, efflux of immature granulocytes into peripheral blood, activation of CD8 T cells, which infiltrate lungs, and transient liver disease. In particular, the elevation of serum gamma-glutamyl transferase (GGT) and histological signs of cholestasis were highly specific for patients with severe disease. In contrast, patients with fatal course of COVID-19 failed to upregulate markers of inflammation, showed dyscoordination of immune response and progressed towards acute kidney failure. COVID-19 is a disease with multi-organ affinity characterized by activation of innate and cellular adaptive immunity. Biliary lesion with elevation of GGT and organ-infiltration of IL-6 producing cells are defining characteristic for patients with fulminant disease.
