When separating AKI patients into groups with and without sepsis, we observed that patients with sepsis-associated AKI had lower levels of albumin-adjusted free thiol levels (6.8 (2.0, 7.9) μmol/g) compared to patients without both sepsis and AKI (8.4 (5.8, 10.8) μmol/g; p < 0.05). This evidence concerns the gene ALB and acute kidney injury.
