A study by Saygili et al. [10] compared children hospitalized due to SARS-CoV-2 associated pneumonia and healthy controls: patients showed significantly higher values of urinary biomarkers for AKI (NGAL-1, KIM-1, IL-18) and albuminuria, even in the absence of proper AKI diagnosis. The gene discussed is HAVCR1; the disease is susceptibility to pneumonia measurement.
