The worldwide prevalence of diabetes and associated metabolic diseases has dramatically increased. Pharmacological treatment of diabetes is still limited. Hordenine (HOR), a phenethylamine alkaloid, is a natural constituent in many plants. The present study was designed to explore the possible anti-diabetic effect of HOR in streptozotocin (STZ)-induced diabetic mice. Combined treatment of HOR and insulin significantly reduced fasting and postprandial blood glucose level in diabetic mice. HOR and insulin did not show evident protective effect against structural and functional injuries of pancreas...

Ochratoxin A (OTA), is a natural contaminant of the food chain worldwide involved in the development of different type of cancers in animals and humans. Several studies suggested that oxidative damage might contribute to increase the cytotoxicity and carcinogenicity capabilities of OTA. The aim of this study was to evaluate the possible protective effect of δ-tocotrienol (Delta), a natural form of vitamin E, against OTA-induced nephrotoxicity. Male Sprague-Dawley rats were treated with OTA and/or Delta by gavage for 14 days...

Based on the abnormally increased expression of CD44 receptors on renal tubule epithelial cells during ischemia/reperfusion-induced acute kidney injury (AKI), we developed a hyaluronic acid-curcumin (HA-CUR) polymeric prodrug targeting to epithelial cells and then relieving oxidative stress damages. The water solubility of HA-CUR was significantly enhanced and approximately 27-fold higher than that of CUR. Cellular uptake test showed HA-CUR was preferably internalized by H2 O2 -pretreated tubular epithelial (HK-2) cells compared with free CUR benefiting from the specific binding between HA and CD44 receptors...

Chromium poisoning can cause renal failure and death. Chromium intoxication may be managed using L-ascorbic acid (vitamin C) therapy. However, the evidence supporting the effectiveness of this treatment is insufficient, and the mechanism of action has not been clarified in renal cells. In this study, our results showed that the optimal regimen of L-ascorbic acid therapy in human epithelial renal proximal tubule cells, HK-2 cells, was 30 μg/mL. Supplementation of L-ascorbic acid with 30 μg/mL and within 8 h of chromium intoxication (K2 Cr2 O7, Cr6+ ) was effective to inhibit renal tubular cell damage by blocking generation of free radicals, cell apoptosis, and autophagy...

Nickel (Ni) is an important environmental toxicant that can cause cancer and cardiovascular disease. The aim of this study was to examine the protective effects of troxerutin (Txn) Ni-induced renal dysfunction in rats using biochemical and histopathological approaches. Nickel (20 mg/kg body weight [b.w.]/day) was administered intraperitoneally (i.p.) for 20 days. Renal damage from Ni toxicity was evident from the changed levels of serum and urinary markers in Ni-treated rats. The levels of lipid peroxidation markers also significantly increased, while the levels of nonenzymatic and enzymatic antioxidants significantly decreased in the kidney of Ni-intoxicated rats...

BACKGROUND: Although iodinated contrast (IC) agents are commonly used in endovascular aneurysm repair (EVAR), perioperative use in patients with renal dysfunction or IC allergies is avoided. Carbon dioxide (CO2 )-guided angiography is a promising alternative. We aimed to evaluate short-term and mid-term outcomes of EVAR using CO2 -guided angiography. METHODS: Three hundred and eighty-one patients who underwent EVAR from January 2012 to September 2016 were retrospectively reviewed and divided into an IC-EVAR group (n=351) and CO2 -EVAR group (n=30)...

Rapamycin, an immunosuppressant, is widely used in patients with kidney transplant. However, the therapeutic effects of rapamycin remain controversial. Additionally, previous studies have revealed deleterious effects of rapamycin predominantly when administered for ≥24 h. Few studies, however, have focused on the short-term effects of rapamycin administered only during the initial reperfusion phase. As such, we designed this study to explore the potential effects and mechanisms of rapamycin under a specific therapeutic regimen in which rapamycin is mixed in the perfusate during the initial reperfusion phase (within 24 h)...

In the face of adversity, the fetal kidney doesn't fare well. When resources are limiting due to pregnancy complications such as placental insufficiency, maternal hypoxia, or nutrient deficiencies, kidney development is often compromised, showing signs of reduced growth, defective nephrogenesis, and abnormal morphology.

BACKGROUND: Generation of smoke is inevitable during surgical procedures. Some volatile organic compounds (VOCs) in surgical smoke are known to be strong carcinogens. We used a prototype of a multi-layered complex filter in an attempt to eliminate VOCs. METHODS: From June 2015 to July 2015, 20 patients underwent transperitoneal laparoscopic nephrectomy for renal cell carcinoma. Smoke (pre-filter) was collected 20 min after the electrocautery device was first used during the surgery, by the direct collection method, with a 5-L Tedlar® gas-sampling bag...

BACKGROUND: Hyperlipidaemia is a risk factor for the progression of chronic kidney disease (CKD), which is a frequent comorbidity in patients with HIV-1 infection, but the renal effects of statins remain unclear. METHODS: We performed an observational, prospective study of HIV-infected patients on suppressive antiretroviral therapy, with CKD and hyperlipidaemia, and starting a lipid-lowering treatment with rosuvastatin, atorvastatin or omega-3 fatty acids. CKD was defined as an estimated glomerular filtration rate (eGFR) ≤ 60 mL/min/1...

REVIEW
Beatrice Richter, Christian Faul
Fibroblast growth factor (FGF) 23 is a phosphaturic hormone whose physiologic actions on target tissues are mediated by FGF receptors (FGFR) and klotho, which functions as a co-receptor that increases the binding affinity of FGF23 for FGFRs. By stimulating FGFR/klotho complexes in the kidney and parathyroid gland, FGF23 reduces renal phosphate uptake and secretion of parathyroid hormone, respectively, thereby acting as a key regulator of phosphate metabolism. Recently, it has been shown that FGF23 can also target cell types that lack klotho...

Extensive kidney fibrosis occurs in several types of chronic kidney diseases. PBI-4050, a potentially novel first-in-class orally active low-molecular weight compound, has antifibrotic and antiinflammatory properties. We examined whether PBI-4050 affected the progression of diabetic nephropathy (DN) in a mouse model of accelerated type 2 diabetes and in a model of selective tubulointerstitial fibrosis. eNOS-/- db/db mice were treated with PBI-4050 from 8-20 weeks of age (early treatment) or from 16-24 weeks of age (late treatment)...

Acute kidney injury (AKI) represents the most frequent complication after cardiac surgery. Macrophage migration inhibitory factor (MIF) is a stress-regulating cytokine that was shown to protect the heart from myocardial ischemia-reperfusion injury, but its role in the pathogenesis of AKI remains unknown. In an observational study, serum and urinary MIF was quantified in 60 patients scheduled for elective conventional cardiac surgery with the use of cardiopulmonary bypass. Cardiac surgery triggered an increase in MIF serum concentrations, and patients with high circulating MIF (>median) 12 hours after surgery had a significantly reduced risk of developing AKI (relative risk reduction, 72...

As a potent chemotherapy drug, cisplatin is also notorious for its side effects including nephrotoxicity in kidneys, presenting a pressing need to identify renoprotective agents. Cisplatin nephrotoxicity involves epigenetic regulations, including changes in histone acetylation. Bromodomain and extra-terminal (BET) proteins are "readers" of the epigenetic code of histone acetylation. Here, we investigated the potential renoprotective effects of JQ1, a small molecule inhibitor of BET proteins. We show that JQ1 significantly ameliorated cisplatin-induced nephrotoxicity in mice as indicated by the measurements of kidney function, histopathology, and renal tubular apoptosis...

As the number of kidney transplants continues to rise, so does the number and complexities of surgical-related complications, which may be associated with increased morbidity and potentially graft loss. Ureteral stenosis, the most prevalent urological complication, may require diverse techniques for surgical correction depending on several recipient and graft abnormalities. Here we report the surgical and clinical outcomes of a 62-year-old man with a postransplant pyeloureterostomy stricture successfully treated with ureterocalycostomy after a lower pole nephrectomy...

Polyomavirus-associated nephropathy is a pertinent cause of poor renal allograft survival. Absence of defensive immunity toward BK polyomavirus may favor the occurrence of BK polyomavirus-active infection and influence the progression to polyomavirus-associated nephropathy. Humoral immune responses may offer incomplete protection. In this review, available data on both humoral and cellular immunity were examined, with a concentration on BK polyomavirus-specific T cells; in addition, their roles in BK polyomavirus cellular immune response and immunotherapy were discussed...

BACKGROUND AND AIM: The synthetic drug fenoldopam mesylate (FM) may have a renoprotective role, and a "renal dose" of 0.1 µg/kg/min intravenous (IV) infusion of FM has been reported as able to increase renal blood flow without affecting systemic blood pressure. But conclusive data are still lacking. We aimed to investigate by color-Doppler ultrasonography the effects of IV administration of FM at this dosage in hypertensive chronic kidney disease (CKD) patients, and verify whether it may induce any systemic hemodynamic alteration...

Cyclophosphamide (CP) is a common chemotherapeutic agent that is effective against a wide variety of tumors. The associated hepatotoxicity and nephrotoxicity, however, limit its therapeutic use. Naringin (NG) is a natural flavanone glycoside that has pharmacological and therapeutic activities, such as anti-inflammation, anti-apoptotic, and antioxidant properties. Therefore, the present study was undertaken to evaluate the protective effect of NG against CP-induced hepatotoxicity and nephrotoxicity in rats. Rats were pre-treated with NG (50 and 100 mg/kg b...
