Urine biomarkers and their associations with ATN in patients with nephrotic syndrome: Positive correlations were observed of urinary concentrations of KIM-1 (r = 0.4884 95% CI 0.1856 to 0.7065, P = 0.0008) and of NGAL (0.5299 95% CI 0.2290 to 0.7383, P < 0.001) with the percentage of renal cortex with histological lesions of ATN. The gene discussed is HAVCR1; the disease is nephrotic syndrome.
