PURPOSE: To evaluate the preventive effect of ascorbic acid on sevoflurane-induced acute renal failure in an experimental rat model. METHODS: Twenty-four adult male Wistar rats were randomly distributed into three groups. Subjects were allocated into 3 groups: Group I received sevoflurane only, whereas Groups II and III had moderate (150 mg/kg) and high (300 mg/kg) doses of AA in addition to sevoflurane, respectively. Rhabdomyolysis and myohemoglobinuric ARF was formed by intramuscular administration of glycerol on the upper hind limb on the 15th minute of inhalation anesthesia...

Fibrosis is a final common pathology in cardiovascular disease(1). In the heart, fibrosis causes mechanical and electrical dysfunction(1,2) and in the kidney, it predicts the onset of renal failure(3). Transforming growth factor β1 (TGFB1) is the principal pro-fibrotic factor(4,5) but its inhibition is associated with side effects due to its pleiotropic roles(6,7). We hypothesised that downstream effectors of TGFB1 in fibroblasts could be attractive therapeutic targets and lack upstream toxicities. Using integrated imaging-genomics analyses of primary human fibroblasts, we found that Interleukin 11 (IL11) upregulation is the dominant transcriptional response to TGFB1 exposure and required for its profibrotic effect...

Populations of three resident Gyps species (Indian white-backed vulture Gyps bengalensis, Indian vulture Gyps indicus, and Slender-billed vulture Gyps tenuirostris) in India have decreased by more than 90% since mid 1990s, and they continue to decline. Experimental studies showed the mortality of vultures to be due to renal failure caused by diclofenac, a nonsteroidal anti-inflammatory drug. India, Pakistan, and Nepal banned the veterinary usage of diclofenac in 2006 to prevent further decline in vulture population...

AIMS: Renal dysfunction (RD) is associated with increased morbidity and mortality in heart failure (HF). At present, no specific treatment for patients with RD, to prevent progression of HF, has been developed. How different hormone axes-and thereby potential treatment options-are affected by RD in HF warrants further investigations. METHODS AND RESULTS: Patients with left ventricular ejection fraction (LVEF) <0.45% were enrolled prospectively from an outpatient HF clinic...

AIMS: Lipocalin-2 is a pro-inflammatory molecule characterized by a highly diversified pattern of expression and structure-functional relationships. In vivo, this molecule exists as multiple variants due to post-translational modifications and/or protein-protein interactions. Lipocalin-2 is modified by polyamination, which enhances the clearance of this protein from the circulation and prevents its excessive accumulation in tissues. On the other hand, animal studies suggest that non-polyaminated lipocalin-2 (npLcn2) plays a causal role in the pathogenesis of obesity-associated medical complications...

In crystallopathies, crystals or crystalline particles of environmental and metabolic origin deposit within tissues, induce inflammation, injury and cell death and eventually lead to organ-failure. The NLRP3-inflammasome is involved in mediating crystalline particles-induced inflammation, but pathways leading to cell death are still unknown. Here, we have used broad range of intrinsic and extrinsic crystal- or crystalline particle-sizes and shapes, e.g. calcium phosphate, silica, titanium dioxide, cholesterol, calcium oxalate, and monosodium urate...

Hypertension is the strongest or one of the strongest risk factors for almost all different cardiovascular diseases acquired during life, including coronary disease, left ventricular hypertrophy and valvular heart diseases, cardiac arrhythmias including atrial fibrillation, cerebral stroke and renal failure. The continuous relationship between blood pressure and cardiovascular and renal events makes the distinction between high normal blood pressure and hypertension based on arbitrary cut-off values for blood pressures...

Overdosing of the drugs, drug-drug interaction or drug related adverse effects are the risk factors of drug-induced nephrotoxicity. Since the use of some nephrotoxic drugs is still unavoidable in clinic, to understand the pathogenic mechanisms of nephrotoxicity of these drugs is critical to decrease the incidence of kidney injury. Early detection of drug-induced nephrotoxicity and reduce the therapeutic side effects are still accessible approaches to avoid the end stage of renal failure. Therefore, the discovery or development of the early and accurate diagnostic biomarkers is an effective prevention strategy for drug-induced kidney impairment...

Statins are among the most widely prescribed medications worldwide. Acute rhabdomyolysis constitutes a potentially life-threatening side effect regardless of whether statins are administered alone or in combination. The potentially fatal combination of a statin and fusidic acid has been well described in the literature. Acute renal failure can be a direct consequence of this drug-drug interaction. We present a case of a 79-year-old woman who presented to our Emergency Department with a one-week history of limb weakness, myalgia, and inability to stand and walk...

Berberine (BBR) has previously been found to exert beneficial effects on renal injury in experimental rats. However, the mechanisms underlying these effects are not yet fully understood. Tumor necrosis factor (TNF) receptor-associated factor 5 (TRAF5) has been demonstrated to mediate the activation of nuclear factor-κB (NF-κB), which has been implicated in the pathogenesis of chronic kidney disease (CKD). The aim of this study was to investigate the effects of BBR on kidney injury and the activation of the NF-κB signaling pathway in mouse podocytes...

Acute renal failure is a serious complication of treatment with the anticancer drug cisplatin. Cisplatin exerts a cytotoxic effect on renal cells by inducing apoptosis through activating the tumor suppressor p53, nuclear factor‑κB (NF‑κB) and mitogen‑activated protein kinase (MAPK)/p38 pathways. Effects of protein extracts of the brown seaweed Porphyra yezoensis (P. yezoensis) on cytotoxicity, inflammation and cell proliferation have been reported; however, the effects of P. yezoensis protein (PYP) extract on cisplatin‑induced renal injury have remained elusive...

Induction therapy of proliferative lupus nephritis still requires the use of unselective immunosuppressive drugs with significant toxicities. In search of more specific drugs with equal efficacy but fewer side effects we considered blocking pro-inflammatory chemokine monocyte chemoattractant protein-1 (MCP-1/CCL2) and homeostatic chemokine stromal cell-derived factor-1 (SDF-1/CXCL12), which both contribute to the onset and progression of proliferative lupus nephritis yet through different mechanisms. We hypothesized that dual antagonism could be as potent on lupus nephritis as the unselective immunosuppressant cyclophosphamide (CYC)...

While statins are widely accepted as a keystone for secondary prevention of cardiovascular disease in the general population, statin treatment in chronic renal failure is still debated. Statins have shown no benefit on cardiovascular outcomes in 4D, AURORA, and SHARP trials conducted in patients on dialysis. However, no study has yet compared statin treatment after acute myocardial infarction in end-stage renal disease (ESRD) patients. Statin treatment significantly decreases overall mortality in ESRD patients with acute myocardial infarction compared to the non-statin group...

It is well known that some disorders can cause concomitant kidney dysfunction with lung involvement. These syndromes, characterized by the simultaneous presence of intra-alveolar hemorrhage and acute glomerulonephritis, are caused by numerous and variable disorders. The most frequent are the antineutrophil cytoplasmic antibodies (ANCA)-associated vasculitis and Goodpasture syndrome. A quick discerning of the underlying causes and initiation of adequate treatment is crucial to prevent acute respiratory failure and irreversible loss of renal function...
