Numerous biochemical markers, including cytokines, procalcitonin, cardiac markers, lactate, lactate dehydrogenase (LDH), C-reactive protein (CRP), D-dimer, aspartate aminotransferase (AST), neuron-specific enolase, neutrophil count, neutrophils-to-lymphocytes ratio, brain natriuretic peptide (BNP), and its N-terminal pro-hormone have been associated with the severity of COVID-19 [4, 5]. This evidence concerns the gene CRP and COVID-19.
