Renal fibrosis is the final common pathway of all varieties of progressive chronic kidney disease. However, there are no effective therapies to prevent or slow the progression of renal fibrosis. Niclosamide is a US Food and Drug Administration-approved oral antihelminthic drug used for treating most tapeworm infections. Here, we demonstrated that phosphate niclosamide, the water-soluble form of niclosamide, significantly reduced proteinuria, glomerulosclrotic lesions, and interstitial fibrosis in a murine model of adriamycin nephropathy...

Background. There is a gender disparity in the incidence, prevalence, and progression of renal disease. The object of this paper is to evaluate the presence and type of renal lesion in normogonadic and hypogonadic male rats in a mild hyperuricemia induced condition and exposed to a high-fructose diet. Methods. 56 adult male Wistar rats were used. Animals were divided into two groups, one normogonadic (NGN) and one hypogonadic (HGN), and each group was divided into four subgroups in accordance with the treatment: control with only water (C), fructose (F), oxonic acid (OA), and fructose + oxonic acid (FOA)...

Mammalian target for rapamycin complex 1 (mTORC1) is a common target for the action of immunosuppressant macrolide rapamycin and glucose-lowering metformin. Inhibition of mTORC1 can exert both beneficial and detrimental effects in different pathologies. Here, we investigated the differential effects of rapamycin (1.2 mg/kg per day delivered subcutaneously for 6 weeks) and metformin (300 mg/kg per day delivered orally for 11 weeks) treatments on male Zucker diabetic fatty (ZDF) rats that mimic the cardiorenal pathology of type 2 diabetic patients and progress to insulin insufficiency...

Beetroot has a high concentration of inorganic nitrate, which can serially reduced to form nitrite and nitric oxide (NO) after oral ingestion. Increased renal resistive index (RRI) measured by Doppler ultrasonography is associated with higher cardiovascular mortality in hypertensive patients with reduced renal function over time defined as chronic kidney disease (CKD). Our aim was to investigate whether the supplementation of dietary nitrate by administration of beetroot juice is able to reduce blood pressure and renal resistive index (RRI) as prognostic markers for cardiovascular mortality in CKD patients...

The syndrome of heart failure involves complex pathophysiologic mechanisms and is associated with extremely high-morbidity, mortality and economic costs. This growing global epidemic has diverse etiologies and is fundamentally characterized by dyshomeostasis between heart and kidneys, leading to development and progression of the cardiorenal syndrome. Excessive and sustained sympathoexcitation has emerged as a single prominent factor involved in the structural and functional dysfunction of multiple organ systems during this disease...

BACKGROUND: Autosomal Dominant Polycystic Kidney Disease (ADPKD) patients have an impaired urine concentrating capacity. Increased circulating vasopressin (AVP) concentrations are supposed to play a role in the progression of ADPKD. We hypothesized that ADPKD patients have a more severely impaired urine concentrating capacity in comparison to other patients with chronic kidney disease at a similar level of kidney function, with consequently an enhanced AVP response to water deprivation with higher circulating AVP concentrations...

BACKGROUND: Besides its essential role for water homeostasis, arginine vasopressin (AVP) may have deleterious effects on the kidney. Copeptin, a surrogate marker for AVP, has been shown to be related to renal outcome in patients with diabetic nephropathy and polycystic kidney disease. We investigated the association of copeptin with disease severity and progression in immunoglobulin A nephropathy (IgAN). METHODS: We included a prospective cohort of 59 patients with biopsy proven IgAN...

Chronic kidney disease (CKD) has emerged as a global public health problem. Although the incidence and prevalence of CKD vary from one country to another, the estimated worldwide prevalence is 8-16%. The complications associated with CKD include progression to end-stage renal disease (ESRD), mineral and bone disorders, anaemia, cognitive decline and elevated all-cause and cardiovascular (CV) mortality. As a result of progressive nephron loss, patients with late-stage CKD are permanently exposed to uraemic toxins...

The European Medicines Agency approved tolvaptan to slow cyst growth and renal failure progression in adults with ADPKD, glomerular filtration 60 mL/min x 1.73 m2 and rapidly progressive disease. In a multicenter 3-year study, conducted on 1,445 patients with non-genotyped ADPKD, ages 18-50 years, predicted creatinine clearance 60 mL/min and kidney total volume 750 mL, tolvaptan slowed kidney failure progression (-23%-46% for different objectives) and reduced kidney volume increase and pain without effects on hypertension and albuminuria...

The burden of cardiovascular diseases (CVD) in general and heart failure (HF) in particular continues to increase worldwide. CVD are major contributors to death and morbidity and recognized as important drivers of healthcare expenditure. Chronic overactivity of the renin-angiotensin-aldosterone system (RAAS) plays a key role in human hypertension and HF pathophysiology. RAAS is fundamental in the overall regulation of cardiovascular homeostasis through the actions of hormones, which regulate vascular tone, and specifically blood pressure through vasoconstriction and renal sodium and water retention...

Acute kidney injury (AKI) is an important risk factor for incident chronic kidney disease (CKD). Clinical studies disclose that ensuing CKD progresses after functional recovery from AKI, but the underlying mechanisms remain illusive. Using a murine model representing AKI-CKD continuum, we show angiotensin II type 1a (AT1a) receptor signaling as one of the underlying mechanisms. Male adult CD-1 mice presented severe AKI with 20% mortality within 2 weeks after right nephrectomy and left renal ischemia-reperfusion injury...

To evaluate the associations between exposure to arsenic in drinking water and the progression of chronic kidney disease (CKD), we conducted a study in Taiwan. We recruited 8854 participants from a nationwide health screening program from 2000 to 2009 who were at least 20 years old and had two checkups in a 24-month period with at least 12 months apart. We defined CKD as having an estimated glomerular filtration rate (eGFR)<90ml/min/1.73m(2) or renal dysfunction demonstrated by proteinuria and a rapid progression of CKD as a decline in eGFR>5ml/min/1...

Diabetic nephropathy (DN) is the leading cause of end-stage renal disease in diabetes mellitus. Oxidative stress, insulin resistance and pro-inflammatory cytokines have been shown to play an important role in pathogeneses of renal damage on type 2 diabetes mellitus (DM). Inonotus obliquus (IO) is a white rot fungus that belongs to the family Hymenochaetaceae; it has been used as an edible mushroom and exhibits many biological activities including anti-tumor, anti-oxidant, anti-inflammatory and anti-hyperglycemic properties...

HYPOTHESIS/INTRODUCTION: Renal fibrovascular injury often persists in chronic kidney disease patients treated with renin-angiotensin system blockers. Intriguingly, early outgrowth cell-derived factor infusion also inhibits chronic renal injury. We sought to determine whether early outgrowth cell-derived factor administration provides further renoprotection when added to renin-angiotensin system blockade. MATERIALS AND METHODS: Conditioned medium was generated by incubating rat early outgrowth cells with serum-free endothelial basal medium-2 to collect their secreted factors...

Chronic kidney disease (CKD) is becoming increasingly widespread in the world. Slowing its progression means to prevent uremic complications and improve quality of life of patients. Currently, a low-protein diet (LPD) is one of the tools most used in renal conservative therapy but a possible risk connected to LPD is protein-energy wasting. The aim of this study is evaluate the possible correlation between LPD and malnutrition onset. We enrolled 41 CKD patients, stages IIIb/IV according to K-DIGO guidelines, who followed for 6 weeks a diet with controlled protein intake (recommended dietary allowance 0...
