Do high values of CRP and NLR predict severe outcomes in patients with COVID-19?
Combining CRP and NLR values may help in the early detection and risk stratification of severe COVID-19 to guide clinical management.
Recent studies found that during the entire hospital stay, NLR correlates well with severity (significantly increased at week 2 (threshold) and significantly decreases down by week 3) 10.Several studies have shown that the level of CRP and the value of NLR are independent risk factors for severe COVID-19 and have concluded that high NLR and CRP can serve as an early marker of severe 9].This observation illustrates the fact that it can be useful to combine the NLR value with the level of CRP as well as lymphopenia and neutrophilia to predict terrible outcomes at admission.In addition to rapid intervention, we concluded early detection and risk stratification of COVID-19 by warning signs within clear and convenient predictive measures (high values of CRP, NLR, as well as lymphopenia and neutrophilia) to guide clinical practice will greatly reduce mortality, improve the rate of cure and shorten the period of hospital stay.
