ABSTRACT
BACKGROUND:
A cytokine storm conceivably contributes to manifestations of corona virus disease (COVID-19). Inflammatory cytokines such as interleukin-6 (IL-6) cause acute liver injury while serum detectability indicates systemic inflammation.AIMS:
We explored a link between systemic IL-6, related acute phase proteins and liver injury in hospitalized COVID-19 patients.METHODS:
655 patients with suspected COVID-19 were screened in the emergency department at the University Hospital of Innsbruck, Austria, between February and April 2020. 96 patients (â¼15%) were hospitalized with COVID-19. 15 patients required intensive-care treatment (ICT). Plasma aminotransferases, alkaline phosphatase, bilirubin, and gamma glutamyl transferase, as well as IL-6, C-reactive protein (CRP), ferritin and lactate dehydrogenase (LDH) were determined by standard clinical assays.RESULTS:
Of all hospitalized COVID-19 patients, 41 (42%) showed elevated aspartate aminotransferase (AST) concentration. COVID-19 patients with elevated AST exhibited significantly higher IL-6 (p < 0.001), ferritin (p < 0.001), LDH (p < 0.001) and CRP (p < 0.05) serum concentrations compared to patients with normal AST. Liver injury correlated with systemic IL-6 (p < 0.001), CRP (p < 0.001), ferritin (p < 0.001) and LDH (p < 0.001) concentration. In COVID-19 patients requiring ICT, correlations were more pronounced.CONCLUSION:
Systemic inflammation could be a fuel for hepatic injury in COVID-19.Keywords
