<b><i>Introduction:</i></b> Acute kidney injury (AKI) is a frequent complication among patients in the intensive care unit (ICU). The limitations of serum Cr (sCr) in timely detecting AKI are well known. Beta-trace protein (BTP) is emerging as a novel endogenous glomerular filtration rate marker. The aim of this study was to explore the role of BTP as a marker of AKI. <b><i>Methods:</i></b> Patients admitted to the ICU undergoing surgery were included. BTP, sCr, Cystatin C (CysC), and neutrophil gelatinase-associated lipocalin (NGAL) were measured preoperatively, postoperatively (post-op), and at the first (D1) and second (D2) post-op day. AKI was defined as an increase of sCr to ≥1.5-fold from baseline within 2 days after surgery. <b><i>Results:</i></b> Of the 52 patients studied, 10 patients (19%) developed AKI. Patients with AKI were older (69.6 ± 10.7 vs. 58.1 ± 16.7 years, <i>p</i> = 0.043) and had a longer length of ICU stay (13 [IQR 6–49] vs. 6 [IQR 5–8] days, <i>p</i> = 0.032). Between the 2 groups, the evolution of BTP, sCr, CysC, and NGAL over time differed significantly, with overall higher values in the AKI group. ROC analysis for the detection of AKI within 2 days after surgery showed a great accuracy for BTP. The area under the curve (AUC) for BTP post-op; D1; and D2 was, respectively, 0.869 ± 0.049; 0.938 ± 0.035; and 0.943 ± 0.032. The discriminative power of a BTP measurement on D1 was superior in detecting AKI compared to NGAL (adjusted <i>p</i> value = 0.027). We could not detect a significant difference between the AUCs of other biomarkers (NGAL, sCr, and CysC). <b><i>Conclusion:</i></b> Serum BTP is a promising marker for diagnosing AKI in ICU patients undergoing surgery.

Acute kidney injury is a polyetiologic syndrome that is a sudden decrease in kidney function over several days or weeks, causing the accumulation of nitrogenous compounds in the blood, with or without a decrease in urine output. Acute kidney injury is common in hospitalized patients and is associated with increased morbidity, mortality, and financial costs. Currently, acute kidney injury is diagnosed after the onset of symptoms; Available diagnostic tests (presence of creatinine in the blood, microscopy of urine, urine volume) have shortcomings in identifying subclinical acute kidney injury. The lack of therapeutic strategies leads to the fact that the treatment of acute kidney injury is carried out with the help of supportive therapies. Early acute kidney injury detection is essential to minimize damage. Experimental and clinical studies have identified a new biomarker that contribute to the earlier diagnosis of acute kidney injury. With their help, it can be determined that patients are at risk of acute kidney damage. In this review, the authors describe some of the most promising new AKI biomarkers (neutrophil gelatinase-associated lipocalin (NGAL), kidney injury molecule (KIM-1), interleukin-18 (IL18), tissue inhibitor of metalloproteinase-2 (TIMP-2), protein -7, which binds insulin-like growth factor (IGFBP7)).
