COVID-19 patients who developed AKI were more frequently diabetic (55% vs 42%), had lower baseline eGFR (57 ± 26 vs 67 ± 21 mL/min), increased initial median CRP value (78 vs 42 mg/L) and were more often on treatment with antibiotics at hospitalization(60% vs 46%) compared to the COVID-19 patients who did not develop AKI (Table 1). This evidence concerns the gene CRP and COVID-19.
