Acute kidney injury (AKI) is a common and serious disease characterized by a rapid decline in renal function and has an unacceptably high mortality rate with no effective treatment beyond supportive care. AKI can be induced by many factors such as ischemia/reperfusion (IR), sepsis, and drug-induced nephrotoxicity. However, the molecular mechanisms of AKI are poorly understood. A non-coding RNA (ncRNA) is a RNA molecule that is not translated into a protein. NcRNAs play multiple roles in cellular processes, and mutations or imbalances of these molecules within the body can cause a variety of diseases...

The aim of this study is to investigate the mechanism underling cardiac dysfunction during sepsis, as well as the possible amelioration of this dysfunction by exogenous carbon monoxide (CO) administration. For this purpose, rats (six-week-old, male, Sprague-Dawley) were administered LPS (15 mg/kg body weight, i.p. 6 h) and/or CORM (30 mg/kg, i.p.). The decreased left ventricular ejection fraction (EF) observed in LPS group rats was recovered in the LSP + CORM group, confirming the protective role of CO against sepsis-induced myocardial depression...

Despite recent studies have demonstrated that the EGF receptor (EGFR) activation provided a renoprotective role during ischemic and folic acid-induced AKI, the role and regulation mechanism of EGFR in septic AKI remains unclear. Here, gefitinib, a highly selective EGFR inhibitor, abrogated LPS-induced phosphorylation of EGFR, ERK1/2, and STAT3 as well as expression of COX, eNOS, and proinflammatory cytokines in HK-2 cells. In addition, c-Src is an upstream of EGFR signaling pathway and mediates LPS-induced EGFR transactivation...

Acute kidney injury (AKI) is a severe complication of sepsis, which largely contributes to the associated high mortality rate. Tenuigenin (TNG) is a natural product isolated from Polygala tenuifolia root, which possesses anti-inflammatory and anti-oxidant properties. The present study investigated the effects of TNG on sepsis-associated AKI in mice subjected to cecal ligation and puncture (CLP). TNG was demonstrated to alleviate sepsis-induced AKI by reducing pathological changes and significantly decreasing the levels of blood urea nitrogen, serum creatinine and kidney coefficient...

Sepsis and acute kidney injury (AKI) synergistically increase morbidity and mortality in the ICU. How sepsis reduces GFR and causes AKI is poorly understood; one proposed mechanism includes tubuloglomerular feedback (TGF). When sodium reabsorption by the proximal tubules is reduced in normal animals, the macula densa senses increased luminal sodium chloride, then adenosine 1a receptor (A1aR) signaling triggers tubuloglomerular feedback, reducing GFR through afferent arteriole vasoconstriction. We measured GFR and systemic hemodynamics early during cecal ligation and puncture-induced sepsis in wild-type and A1aR knockout mice...

The CD38, possessing ADP-ribosyl cyclase (ADPR-cyclase) and cyclic ADP-ribose hydrolase (cADPR-hydrolase), is able to regulate a variety of cellular activities. However, the role and mechanisms for CD38 in macrophage activation and sepsis-induced acute kidney injury (AKI) remain to be determined. Here we report that in cultured macrophages, Lipopolysaccharide (LPS) could upregulate CD38 expression in time and dose dependent manner. Knocking down or blockade of CD38 in macrophages could inhibit LPS-induced macrophage M1 polarization accompanied by diminished NF-κB signaling activation...

The upregulation of kidney injury molecule-1 (KIM-1) has been extensively studied in various renal diseases and following acute injury; however, the initial mechanisms controlling KIM-1 expression remain limited. In this study, KIM-1 expression was examined in mouse renal cell cultures and in two different models of acute kidney injury (AKI), ischemia-reperfusion (IR) and lipopolysaccharide (LPS)-induced sepsis. KIM-1 mRNA increased in both AKI models and pharmacological inhibition of extracellular signal-regulated kinase 1/2 (ERK1/2) signaling attenuated injury induced KIM-1 expression in the renal cortex...

Treatment of septic acute kidney injury (AKI) has still been beyond satisfaction, although anti-inflammatory therapy is beneficial for sepsis-induced AKI. Compound 5b was derived from natural pyranochalcones and exhibited potent anti-inflammatory activity in adjuvant-induced arthritis. In this study, we aimed to investigate the renoprotective effects and potential mechanism of 5b against lipopolysaccharide (LPS)-induced AKI. C57BL/6 mice and human renal proximal tubule cell line (HK-2 cell) were treated with LPS, respectively...

BACKGROUND: Renal toxicity induced by cisplatin (CisPt) is a clinical issue in patients with or without chronic kidney disease (CKD). Proximal tubular injury can result in acute kidney injury (AKI), which may compromise the course of chemotherapy and the prognosis. The purpose of this study was to investigate the time course of urinary markers of acute tubulotoxicity and to assess the usefulness of such monitoring in a routine clinical setting. METHODS: This work is an open prospective pilot study carried out among 23 patients receiving a platinum-based chemotherapy...

BACKGROUND: Sepsis is a major cause of acute kidney injury (AKI), with high rates of morbidity and mortality. M2 macrophages have been shown to play important roles in the secretion of anti-inflammatory and tissue repair mediators. In this study, we investigate the role of M2 macrophages in sepsis-induced AKI by depleting these cells in vivo through the systemic administration of liposomal clodronate (LC). METHODS: Male Sprague-Dawley rats were subjected to cecal ligation and puncture (CLP) or sham surgery...

Septic acute kidney injury (AKI) associates with poor survival rates and often requires renal replacement therapy. Glucocorticoids may pose renal protective effects in sepsis via stimulation of mitochondrial function. Therefore, we studied the mitochondrial effects of dexamethasone in an experimental inflammatory proximal tubule epithelial cell model. Treatment of human proximal tubule epithelial cells with lipopolysaccharide (LPS) closely resembles pathophysiological processes during endotoxaemia, and led to increased cytokine excretion rates and cellular reactive oxygen species levels, combined with a reduced mitochondrial membrane potential and respiratory capacity...

BACKGROUND: Endothelial activation and damage occur early during sepsis, with activated coagulopathy and playing a major role in the pathophysiology of sepsis-induced acute kidney injury (AKI). The aim of this study was to compare the various biomarkers of endothelial injury with the biomarkers of coagulation and inflammation and to determine a significant predictor of AKI in patients with sepsis. METHODS: We conducted a single-center, retrospective, observational study on patients with sepsis fulfilling the Third International Consensus Definitions for Sepsis and Septic Shock criteria admitted to an adult intensive care unit (ICU) at a university hospital from June 2011 to December 2016...

Though significant progress has been made towards new diagnostic approaches for early detection of acute kidney injury (AKI) induced by different factors, there is still an urgent demand for a more specific and predictive biomarker for each type. The aim of this study is to unravel the potential diagnostic utility of circulating osteoprotegerin (OPG) in septic patients who developed AKI in the ICU, compared to cystatin C (a renal function maker) and KIM-1 (a kidney damage marker). Eighty patients (male = 43, female = 37) with ages ranging from 42 to 46 years and with sepsis, 40 of whom developed AKI, and 30 healthy controls were enrolled in this prospective study...

REVIEW
Joanne M Dennis, Paul K Witting
Acute kidney injury causes significant morbidity and mortality in the community and clinic. Various pathologies, including renal and cardiovascular disease, traumatic injury/rhabdomyolysis, sepsis, and nephrotoxicity, that cause acute kidney injury (AKI), induce general or regional decreases in renal blood flow. The ensuing renal hypoxia and ischemia promotes the formation of reactive oxygen species (ROS) such as superoxide radical anions, peroxides, and hydroxyl radicals, that can oxidatively damage biomolecules and membranes, and affect organelle function and induce renal tubule cell injury, inflammation, and vascular dysfunction...

BACKGROUND: Acute kidney injury (AKI) is a severe disease in critically ill patients. Neutrophil infiltration into kidney was associated with the development of AKI, and P-selectin may be involved in the process of neutrophil recruitment in kidney. This study aimed to explore the potential effect of platelet-derived P-selectin on neutrophil recruitment in a mouse model of sepsis-induced AKI. METHODS: A total of 30 C57BL/6 male mice were divided into five groups (n = 6 in each): sham group, sepsis group, anti-Ly6G group, anti-P-selectin group, and platelet depletion group...

We hypothesized that patients with sepsis and AKI, especially patients without preserved renal function, and treated with continuous veno-venous hemodiafiltration (CVVHDF), have lower risk for mortality than patients treated with continuous veno-venous hemofiltration (CVVH). Patients were included if they fulfilled the diagnosis of severe sepsis or septic shock, suffered AKI and received continuous renal replacement therapy (CRRT) in intensive care unit. There were 62 patients treated by CVVH and 75 treated by CVVHDF...

Septic shock is the most common cause of acute kidney injury (AKI), but the underlying mechanisms remain unclear and no targeted therapies exist. Lysophosphatidic acid (LPA) is a bioactive lipid which in vivo administration was reported to mitigate inflammation and injuries caused by bacterial endotoxemia in the liver and lung. The objective of the present study was to determine whether LPA can protect against sepsis-associated AKI. C57BL/6 mice were treated with LPA 18:1 (5 mg/kg, i.p.) 1 h before being injected with the endotoxin lipopolysaccharide (LPS), and AKI was evaluated after 24 h...

Sepsis is a serious clinical problem. Negative regulation of innate immunity is associated with sepsis progression, but the underlying mechanisms remains unclear. Here we show that the receptor CD300f promotes disease progression in sepsis. CD300f (-/-) mice were protected from death after cecal ligation and puncture (CLP), a murine model of septic peritonitis. CD300f was highly expressed in mast cells and recruited neutrophils in the peritoneal cavity. Analysis of mice (e.g., mast cell-deficient mice) receiving transplants of wild-type or CD300f (-/-) mast cells or neutrophils indicated that CD300f deficiency did not influence intrinsic migratory abilities of neutrophils, but enhanced neutrophil chemoattractant production (from mast cells and neutrophils) in the peritoneal cavity of CLP-operated mice, leading to robust accumulation of neutrophils which efficiently eliminated Escherichia coli...

Esculentoside A (EsA), a saponin isolated from Phytolacca esculenta, can attenuate acute liver and lung injury. However, whether EsA has a protective effect against sepsis-induced acute kidney injury (AKI) has not been reported. In this study, EsA (2.5, 5, or 10 mg/kg) was given to rats with sepsis induced by cecal ligation and puncture (CLP). We found that EsA improved the survival of septic rats in a dose-dependent manner. In addition, EsA lowered the kidney tubular damage score and decreased blood urea nitrogen and creatinine...
