AKI was also a risk factor associated with higher mortality rates in older patients (>45 years) (n=150 (73.2%)), those needing invasive ventilation (n=163 (88.1%)), and patients with elevated total leucocyte count (TLC) (n=130 (79.3%)), lactate dehydrogenase (LDH) (n=159 (72.9%)), interleukin-6 (IL-6) (n=153 (72.2%)), and serum ferritin (n=51 (73.7%)) and hypoalbuminemia (n=152 (73.1%)). This evidence concerns the gene IL6 and acute kidney injury.
