A recent study of the single-cell transcriptome analysis found that ACE2 genes were significantly expressed in podocytes and proximal convoluted tubules as potential hosts cells targeted by SARS-CoV-2; this work suggests that the kidney might be an important target organ for SARS-CoV-2.24 A retrospective cohort study reported that mortality was higher in COVID-19 with AKI versus COVID-19 patients without AKI (60.5% vs 27.4%), and AKI was an independent predictor of mortality.25 Our study revealed that AKI incidence rates of 14.0% in all hospitalized patients and 61.3% in the nonsurvivors. This evidence concerns the gene ACE2 and COVID-19.
