This study aimed to explore the role of long non-coding RNA NEAT1 in sepsis-induced acute kidney injury (AKI). The expression levels of NEAT1 in sepsis-induced AKI patients were detected. The rat mesangial cells (RMCs) were treated with lipopolysaccharide (LPS) to induce cell injury. Then, the effects of NEAT1 suppression on the cell viability, apoptosis, cytokines expression, and oxidative stress in the LPS-stimulated RMCs were tested. The regulatory miRNA of NEAT1, as well as the target genes of this miRNA, were investigated...

Acute kidney injury (AKI) often occurs in 5% hospitalized patients and in 50% sepsis patients with acute renal dysfunction. However, there is no safe and effective therapeutic strategies until now. Hypoxia condition is closely related to renal injuries and function under AKI. As HIF-1α is critical for cellular response to hypoxia, we investigated the protective effect of HIF-1α in a rat AKI model. We found that HIF-1 α injection improved the survival of rat with AKI, and the level of Cr and BUN was also increased...

Acute kidney injury (AKI) is one of the most common complications of sepsis. The roles of autophagy in AKI have been demonstrated in previous studies. Sequestosome‑1 (p62) has been demonstrated to serve essential roles in autophagy. The dysregulation of autophagy causes p62 accumulation, which is associated with increased inflammation and tumorigenesis. However, the expression patterns and role of p62 in septic AKI remain unknown. The present study detected the renal autophagy level, and the expression and localization of p62, in a lipopolysaccharide (LPS)‑induced AKI mouse model...

For continuous renal replacement therapy (CRRT), the extracorporeal filter provides solute depuration, fluid removal, and control of electrolyte and acid-base balance in critically ill patients with acute kidney injury (AKI). The membranes comprising CRRT filters are almost exclusively based on hollow fiber designs and, while adapted from the chronic hemodialysis field, have features that are specific to the requirements of CRRT nevertheless. In addition, these devices have evolved through the 40 years of CRRT in response to changes in clinical practice and the desire to extend the solute removal spectrum...

Managing kidney transplant patients in an acute medical unit can be challenging, as patients have a single functioning kidney, underlying chronic kidney disease, and are immunosuppressed. Transplant patients develop AKI for all usual reasons but the differential diagnosis is wider and includes specific problems, such as obstruction of a single functioning kidney, vascular thrombosis, rejection, drug toxicity and drug-induced thrombotic microangiopathy. Septic AKI is common but again, the differential diagnosis of sepsis is wider...

PURPOSE: Early prediction of acute kidney injury (AKI) in septic patients is difficult. This study aimed to assess the values of renal resistive index (RI), central venous pressure (CVP), and their combination in the early prediction of sepsis-induced AKI. METHODS: A prospective cohort study was performed in septic patients. The variables potentially associated with AKI were recorded at admission and compared between the AKI and non-AKI groups. The variables independently associated with sepsis-induced AKI were identified using multivariable logistic regression, and the area under the receiver operating characteristic curve (AUROC) analysis was calculated...

Ursolic acid (UA) as a multiple bioactive native compound has recently been demonstrated to treat sepsis in animal models. However, the beneficial effects of UA in sepsis‑induced acute kidney injury (AKI) are not completely understood. In the present study, the effect of UA on sepsis‑induced AKI in cecal ligation and puncture (CLP) surgery mice was investigated. Renal histomorphological analysis was performed by hematoxylin and eosin staining. The expression of inflammatory markers in the kidney of septic mice was measured by reverse transcription‑quantitative polymerase chain reaction and western blotting...

Previous studies have indicated that monocyte chemoattractant protein-1 (MCP‑1), also referred to as C‑C motif chemokine ligand 2, has a significant role in the pathogenesis of sepsis, however, how microRNAs (miRs) contribute to this process remains to be fully elucidated. In the present study, using a mouse model of disseminated candidiasis, the renoprotective effect of itraconazole (ITR) and adenovirus‑delivered miR‑124 was investigated. The mice were treated with ITR (50 mg/kg) or transfected with miR‑124 mimics via tail‑vein injection 7 days prior to Candida albicans infection...

Acute kidney injury (AKI) is a severe complication of sepsis with a high mortality and morbidity. Pterostilbene (Pte) has been suggested to confer anti-apoptotic and anti-inflammatory effects. In the current study, the effects of Pte on AKI were evaluated in septic mice. Cecal ligation and puncture surgery was performed to induce sepsis. The results suggested that Pte administration significantly decreased the levels of serum urea nitrogen and creatinine, and improved the survival rate of septic mice. Additionally, the renal injury induced by sepsis was attenuated by pterostilbene treatment...

Sepsis affects millions of people worldwide and is associated with acute kidney injury (AKI). Innate and adaptive immune cells have been shown to play an important role in AKI through release of various inflammatory mediators which include reactive oxidant species (ROS). Acetate, a short chain fatty acid produced by gut bacteria has anti-inflammatory properties and has also been shown to modulate oxidative stress in different immune cells. Effects of acetate have been shown to be both GPR43 dependent and independent in different cells/tissues...

Sepsis-associated acute kidney injury (S-AKI) independently predicts mortality among critically ill patients. The role of innate immunity in this process is unclear, and there is an unmet need for S-AKI models to delineate the pathophysiological response. Mammals and zebrafish (Danio rerio) share a conserved nephron structure and homologous innate immune systems, making the latter suitable for sepsis-associated AKI research. We introduced Edwardsiella tarda (E.tarda) to the zebrafish. Systemic E. tarda bacteremia resulted in sustained bacterial infection and dose-dependent mortality...

Sepsis is a major clinical problem associated with significant organ dysfunction and high mortality. The ATP-sensitive P2X7 receptor activates the NLRP3 inflammasome and is a key component of the innate immune system. We used a fluid-resuscitated rat model of fecal peritonitis and acute kidney injury (AKI) to investigate the contribution of this purinergic receptor to renal dysfunction in sepsis. Six and 24 h time-points were chosen to represent early and established sepsis, respectively. A selective P2X7 receptor antagonist (A-438079) dissolved in dimethyl sulfoxide (DMSO) was infused 2 h following induction of sepsis...
