The inflammatory indicators, interleukin-2R [553.50 (319.25, 897.75) U/mL], interleukin-6 [15.57 (3.07, 39.62) pg/mL], tumor necrosis factor-α [8.40 (5.95, 11.75) pg/mL], procalcitonin [0.06 (0.03, 0.15) ng/mL], and high-sensitivity C-reactive protein [40.10 (12.65, 124.10) mg/L], were significantly higher than the normal range and higher in the AKI group than in the non-AKI group (p = 0.006, p = 0.017, p = 0.002, p < 0.0001, p = 0.035). The gene discussed is IL6; the disease is acute kidney injury.
