Background: It is not possible to diagnose acute kidney injury (AKI) in early stages with traditional biomarkers. Kidney injury molecule-1 (KIM-1) is a novel biomarker promising the diagnosis of AKI in early stages. We studied whether urinary and serum KIM-1 (KIM-1 U and KIM-1 S ) concentrations were useful in predicting cisplatin-induced AKI in early stages.
Methods: We prospectively analysed 22 patients on cisplatin treatment. KIM-1 S and KIM-1 U concentrations were assessed in the samples of the patients on four different time periods (before treatment [BT], first [AT1], third [AT3] and fifth [AT5] day after treatment).
Results: KIM-1 U concentrations on the first day after cisplatin treatment in patients with AKI were significantly increased compared to both KIM-1 U concentrations of the same patients BT (P=0.009) and to AT1-KIM-1 U concentrations of the patients without AKI (P=0.008). A receiver operating characteristic analysis revealed that AT1-KIM-1 U concentrations may predict AKI with an 87.5% sensitivity and 93.3% specificity (area under the curve=0.94). KIM-1 S concentrations were not significantly changed between BT and AT periods.
Conclusions: KIM-1 U concentrations may predict cisplatin-induced AKI in early stages with high sensitivity and specificity.

Cisplatin is a platinum-based chemotherapeutic that causes acute kidney injury in over 30% of patients. The aim of this study was to develop a population pharmacokinetic/toxicodynamic (PKTD) model of cisplatin-induced kidney injury that incorporated plasma total platinum and urinary kidney injury molecule-1 (KIM-1) concentrations. Cancer patients receiving their first or second round of cisplatin-containing chemotherapy (n=39) were prospectively randomized to a 5-HT antagonist (5-HTA) antiemetic (ondansetron, granisetron, or palonosetron) and had blood and urine collected over 10 days.

Objective: To explore the protective effect and mechanism of acetate on sepsis-induced acute kidney injury (AKI) in rats.
Methods: Male Sprague-Dawley (SD) rats were divided into sham operation group (Sham group), sepsis group caused by cecal ligation and puncture (CLP group), and acetate pretreatment group [NaA group, gavage sodium acetate (NaA) 300 mg/kg twice a day for 7 consecutive days before CLP] using a random number table method, with 7 rats in each group. The blood was taken from the main abdominal artery 24 hours after modeling, and renal tissue was collected from the rats.

Key Points: In diabetes and CKD, creatinine- and cystatin C–based eGFR has a strong inverse correlation with plasma TNF receptor 1, TNF receptor 2, and soluble urokinase-type plasminogen activator receptor. Higher plasma soluble TNF receptors 1 and 2 and soluble urokinase-type plasminogen activator receptor were each individually associated with mortality, independent of baseline kidney measures.
Background: Several plasma biomarkers of kidney health have been associated with CKD progression in persons with diabetes, but their associations with mortality risk have been largely unexplored.

Background: Anthropogenic vanadium (V) emissions and exposure in the general population have recently increased. Experimental studies have shown that V is a nephrotoxic agent, but little is known about its effects on human kidney health. This work evaluated the association between urinary V concentrations with early kidney damage biomarkers and function in a pediatric population without any disease diagnosed.
