This was comparable to a study by Ortiz et al. (2021) involving 644 patients with COVID-19 and showing significantly higher ferritin (p < 0.001), CRP (p < 0.001), procalcitonin (p < 0.001), D dimer (p = 0.004) and LDH (p = 0.004) among patients with AKI compared to those without AKI. This evidence concerns the gene CRP and acute kidney injury.
