What is this? Some patients with COVID-19 will become critically ill. Research on the role of biomarkers in the disease pathogenesis of COVID-19 might provide useful information for policy makers.
In this rapid review, the authors searched for studies on the correlation between a biomarker and the severity of COVID-19. They did their search before May 2020. They included 34 studies, which were from China (32 studies), Singapore (1) and Italy (1).
What was found: At the time of this review, the included studies showed significantly higher levels of the following biomarkers in patients with severe complications of COIVD-19 infection: C-reactive protein, serum amyloid A, interleukin-6, lactate dehydrogenase, neutrophil-to-lymphocyte ratio, D-dimer, cardiac troponin and renal biomarkers.
At the time of this review, the included studies showed that lymphocytes and platelet count showed significantly lower levels in severely ill patients compared to non-severely ill patients.
