Urine Klotho Is Lower in Critically Ill Patients With Versus Without Acute Kidney Injury and Associates With Major Adverse Kidney Events.

ABSTRACT: Klotho and Fibroblast Growth Factor (FGF)-23 were recently postulated as candidate biomarkers and/or therapeutic targets in acute kidney injury (AKI). We examined whether urine Klotho and serum intact FGF23 levels were differentially and independently associated with major adverse kidney events (MAKE) in critically ill patients with and without AKI. Single-center, prospective, case-control study. ICU in a tertiary medical center. 54 AKI patients and 52 controls without AKI admitted to the ICU. None. AKI was defined by KDIGO criteria and included only AKI stage ≥2. Controls were matched by age, gender, and baseline eGFR. Paired serum and urine samples were obtained 24-48h after AKI diagnosis (cases) or ICU admission (controls). The primary outcome was 90-day MAKE, which was the composite of
