As in our study, data in the literature support the use of CRP as a relevant biomarker in COVID-19 patients, CRP is strongly correlated with disease progression and is an independent predictor of severity, as well as the need for mechanical ventilation.(27-31) More relevant than isolated measurements, the kinetics of CRP seem to be the main point for clinical practice, as demonstrated in our study. Here, CRP is linked to COVID-19.
