The role of NETs and platelet activation in COVID-19 is not well known. This study aimed to evaluate their impact on clinical trajectories. The levels of cfDNA, CitH3, and P-selectin were found to be associated with disease severity and analytical parameters. Higher levels of CitH3 and P-selectin increased the risk of transitioning from the emergency department to the ICU, while higher levels of P-selectin increased the risk of transitioning from the ward to death. Elevated levels of CitH3, cfDNA, and P-selectin decreased the probability of transitioning from the ward to discharge. These findings suggest that NETs and P-selectin levels can be useful in predicting different clinical trajectories.
The role of NETs and platelet activation in COVID-19 is scarcely known. We aimed to evaluate the role of NETs (citrullinated histone H3 [CitH3], cell-free DNA [cfDNA]) and platelet activation markers (soluble CD40 ligand [CD40L] and P-selectin) in estimating the hazard of different clinical trajectories in patients with COVID-19. We performed a prospective study of 204 patients, categorized as outpatient, hospitalized and ICU-admitted. A multistate model was designed to estimate probabilities of clinical transitions across varying states, such as emergency department (ED) visit, discharge (outpatient), ward admission, ICU admission and death. Levels of cfDNA, CitH3 and P-selectin were associated with the severity of presentation and analytical parameters. The model showed an increased risk of higher levels of CitH3 and P-selectin for ED-to-ICU transitions (Hazard Ratio [HR]: 1.35 and 1.31, respectively), as well as an elevated risk of higher levels of P-selectin for ward-to-death transitions (HR: 1.09). Elevated levels of CitH3 (HR: 0.90), cfDNA (HR: 0.84) and P-selectin (HR: 0.91) decreased the probability of ward-to-discharge transitions. A similar trend existed for elevated levels of P-selectin and ICU-to-ward transitions (HR 0.40); In conclusion, increased NET and P-selectin levels are associated with more severe episodes and can prove useful in estimating different clinical trajectories.
