Recent reports indicate that the complement C5a/C5aR pathway and progranulin (PGRN) deficiency both contribute to ischemia-reperfusion (IR)-induced acute kidney injury. However, the underlying relationship between the C5a/C5aR signaling pathway and PGRN expression during acute kidney injury is poorly understood. In this study, we showed that C5aR expression was significantly upregulated after renal IR, and that C5aR deficiency led to a marked increase in PGRN expression and a significant reduction in tubular damage and production of inflammatory cytokines...

The inflammatory response has been shown to be a major contributor to acute kidney injury. Considering that laparoscopic surgery is beneficial in reducing the inflammatory response, we compared the incidence of postoperative acute kidney injury between laparoscopic liver resection and open liver resection. Among 1173 patients who underwent liver resection surgery, 222 of 926 patients who underwent open liver resection were matched with 222 of 247 patients who underwent laparoscopic liver resection, by using propensity score analysis...

OBJECTIVE: Previous studies have demonstrated that urinary kidney injury molecule-1 (uKIM-1) and neutrophil gelatinase-associated lipocalin (uNGAL) were superior to serum creatinine (Scr) in detecting acute kidney injury (AKI), but their ability to predict clinical vancomycin-associated AKI has not been investigated. This study aimed to investigate the abilities of uKIM-1 and uNGAL individually and in combination to predict vancomycin-associated AKI. PATIENTS AND METHODS: Scr, uKIM-1, and uNGAL were measured on the day before and days 1, 2, and 3 of vancomycin therapy in a generalized adult population...

Candidemia is frequent in critically ill patients, especially in combination with an acute kidney injury (AKI). Echinocandins generally are recommended for therapy of such infections. Recent studies found no need for dosage adjustment in patients with end-stage renal disease receiving hemodialysis, or patients with AKI receiving continuous venovenous hemofiltration. The aim of this in vitro study was to examine the adsorption of anidulafungin to the surface of the hemofilter during continuous venovenous hemodialysis (CVVHD) and its effect on anidulafungin concentrations...

Acute kidney injury (AKI) is a global problem which predicts immediate and long-term adverse outcomes. We evaluated the AKI progression to end-stage renal disease, as well as the mortality associated with AKI and the in-hospital readmission rate because of a cardiovascular event in AKI patients admitted in a nephrology ward. A 5-year retrospective study was set in a nephrology department, with a follow-up period of up to 8 years. In a total of 191 patients, mean age was 73.83 ± 12.49 years, and 137 (71...

BACKGROUND: Whether the deleterious effects of carbon dioxide pneumoperitoneum on the kidneys are exacerbated in the obese population remains unknown. We hypothesized that increased body mass index (BMI) is associated with an increased incidence of postoperative acute kidney injury (AKI) in patients undergoing noncardiac laparoscopic surgery. METHODS: Following institutional review board approval, we analyzed data on 8,543 adult patients with American Society of Anesthesiologists physical status scores of I-IV who had inpatient noncardiac laparoscopic surgery from 2005-2014...

PURPOSE OF REVIEW: Drug-induced kidney injury (DIKI) is an important and potentially modifiable cause of acute kidney injury (AKI). The reliance on traditional markers of kidney injury to diagnose DIKI impedes early detection. Biomarkers of DIKI that facilitate early diagnosis and the identification of high-risk patients are essential to ameliorate the clinical burden of this complication. RECENT FINDINGS: Recent progress in this area supports the potential utility of several biomarkers for the diagnosis of DIKI, for the prediction of outcomes and also for monitoring responses to potential nephrotoxic or beneficial therapies...

PURPOSE OF REVIEW: Hepatorenal syndrome (HRS) does not represent the predominant phenotype of acute kidney injury (AKI) in cirrhosis. Early recognition of HRS helps initiate appropriate therapy. The aims of this review are to present redefinition of AKI, to list new biomarkers, to report recent data on vasopressors in HRS and to propose criteria for simultaneous liver and kidney transplantation (SLKT). RECENT FINDINGS: Urine output, which was not part of the definition of AKI might be reconsidered as it has an independent prognostic value...

Despite DNA methylation occurred in acute kidney injury (AKI), how it influenced progression of AKI remains unclear. Methyl-CpG-binding domain protein 2 (MBD2), a protein readers of methylation, was used to analyze the impact of DNA methylation on vancomycin (VAN)-induced AKI. Here, in cultured human kidney tubular epithelial cells (HK-2), we show that knockdown of MBD2 by siRNA attenuated VAN-induced apoptosis, caspase activity, and the expression of BAX and cleaved caspase 3. Interestingly, knockdown of MBD2 by siRNA was associated with the suppression of miR-301a-5p...

The incidence of acute kidney injury in pregnancy (P-AKI) in developed countries is significantly lower than in developing ones, where it is estimated to range between 4 and 26%. Mortality in cases of P-AKI requiring dialysis is high, varying from 20 to 80%. In developing countries, clinical decisions are often based on the availability of services and not on needs. Prenatal surveillance in Mexico does not include serum creatinine, limiting the potential for early diagnosis of AKI and CKD and their differential diagnosis...

We previously demonstrated that renal tubular peptidylarginine deiminase-4 (PAD4) is induced after ischemia reperfusion (IR) injury and this induction of PAD4 exacerbates ischemic acute kidney injury (AKI) by promoting renal tubular inflammation and neutrophil infiltration. However, the mechanisms of renal tubular PAD4 induction after IR remain unknown. Here, we tested the hypothesis that ATP, a pro-inflammatory danger associated molecular pattern (DAMP) ligand released from necrotic cells after IR injury, induces renal tubular PAD4 and exacerbates ischemic AKI via P2 purinergic receptor activation...
