Histone H3 cleavage in COVID-19 patients. The fraction of patients with detectable cleaved or non-cleaved histone H3 (A). Western blot analysis using a polyclonal anti-histone H3 antibody allowed detection of proteolytic cleavage of histone H3, distinguishing between full-sized histone H3 (15 kDa) and a histone H3 fragment (12 kDa) (B). The concentration of histone H3 (C) or NE (D) in cleaved or non-cleaved histone H3 positive samples. The percentage (%) for the positive amount of significantly different clinical events during the stay at the ICU (E). Acute kidney injury (AKI). P-values were considered significant if p < 0.05; *0.05, **0.01, ***0.001.
