Serum levels of the biomarkers at presentation and the Acute Kidney Injury Network (AKIN) stages in patients developing acute kidney injury within 48 hours.
Serum levels of BNP (A), sST2 (B), NGAL (C) and cystatin C (D) at presentation increased significantly across the spectrum of the AKIN stages within 48 hours.
Fig 2.
Serum levels of the biomarkers at presentation and the risk of developing acute kidney injury within 48 hours.
The risk of developing acute kidney injury at 48 hours increased significantly as serum levels of biomarkers rose at presentation.
Fig 3.
Number of biomarkers elevated higher than the cutoff values and the risk of developing acute kidney injury within 48 hours: (A) patients with creatinine levels <1.24 mg/dL; (B) patients with creatinine level ≥1.24 mg/dL.
Regardless of the creatinine level on admission, elevation of ≥2 of the biomarkers higher than the cutoff values provided incremental value in risk stratification of acute kidney injury.
