All biomarkers were equally elevated in patients with IIMs and AKI (KIM1 1.2 VS 1, Activin A 80 VS 72, CD163 193 VS 226, Cys-C 931 VS 1649), without any statistically significant differences, except normalized NGAL which was significantly more elevated in AKI patients (327 IIM vs. 937 AKI, p 0.009) (Table 2B). This evidence concerns the gene LCN2 and acute kidney injury.
