Higher blood levels of inflammatory biomarkers in blood, such as C-reactive protein (CRP), ferritin and D-dimer, have been reported as predictors of a poor outcome in COVID-19 patients 5 . The role of biomarkers associated to inflammation other than those above mentioned, such as calprotectin or growth differentiation factor 15 (GDF-15), is less known. Recently, an experimental study showed a novel function of GDF-15 in the promotion of lung human rhinovirus and virus-associated inflammation, contributing to the severity of respiratory viral infection 10 . We have shown that circulating levels of two emerging inflammatory biomarkers, calprotectin and GDF-15, are significantly higher in COVID-19 patients who died, suggesting a potential role in the evaluation of prognosis in these patients. ./cache/cord-282053-ftjx29lw.txt ./txt/cord-282053-ftjx29lw.txt
