BACKGROUND: The ability of antihyperuricemic therapy to exert renoprotective effects in patients with chronic kidney disease (CKD) is controversial. In the present study, we studied patient characteristics that may mask favorable impact of antihyperuricemic therapy on the progression of CKD. METHODS: This was a single-center, retrospective, follow-up study. One-hundred and seventy-eight CKD patients with hyperuricemia who received febuxostat therapy were included in this study...

Hyperuricaemia is a metabolic disease caused by purine metabolic abnormalities, mainly due to the increased formation or reduced excretion of uric acid. In recent years, it has been proved that hyperuricaemia is an important risk factor for chronic kidney disease (CKD) and cardiovascular disease, and it also takes part in the pathophysiology of metabolic syndrome. In addition, more attention has been concentrated on the pathogenesis or treatment of hyperuricaemia. Since establishing an animal model on hyperuricaemia is the foundation for further researches, several methods to establish the hyperuricaemia model have been developed...

PURPOSE OF REVIEW: This review discusses the recent evidence for a selection of blood-based emerging risk factors, with particular reference to their relation with coronary heart disease and stroke. RECENT FINDINGS: For lipid-related emerging risk factors, recent findings indicate that increasing high-density lipoprotein cholesterol is unlikely to reduce cardiovascular risk, whereas reducing triglyceride-rich lipoproteins and lipoprotein(a) may be beneficial. For inflammatory and hemostatic biomarkers, genetic studies suggest that IL-6 (a pro-inflammatory cytokine) and several coagulation factors are causal for cardiovascular disease, but such studies do not support a causal role for C-reactive protein and fibrinogen...

Hyperuricemia is associated with the development of chronic kidney disease. Epithelial-to-mesenchymal transition (EMT) induced by hyperuricemia is blamed for initiation of renal fibrosis, which is one of the main characters of hyperuricemic nephropathy. Qi-Zhu-Xie-Zhuo-Fang (QZXZF) has been employed clinically for many years to treat patients with hyperuricemic nephropathy, but the mechanism underlying the therapeutic potential remains unclear. In the present study, QZXZF was applied to rats treated with adenine (100mg/kg) and potassium oxonate (300mg/kg) and biochemical estimations, morphology and immunohistochemistry were performed to investigate whether QZXZF can improve hyperuricemia induced renal fibrosis and to explore the possible mechanisms...

Chronic kidney disease and hyperuricemia have been associated to an increased risk and a worse prognosis in acute ischemic stroke. Several mechanisms, including platelet dysfunction, coagulation disorders, endothelial dysfunction, inflammation, and an increased risk of atrial fibrillation could be implicated. The role of serum uric acid in this setting is still object of debate. We enrolled all the consecutive patients admitted to our department for acute ischemic stroke. Cox regression analysis was used to evaluate the risk of in-hospital death considering serum uric acid levels and all the comorbidities...

As a result of the association of a common polymorphism (rs2231142, Q141K) in the ATP-binding cassette G2 (ABCG2) transporter with serum urate concentration in a genome-wide association study, it was revealed that ABCG2 is an important uric acid transporter. This review discusses the relevance of ABCG2 polymorphisms in gout, possible etiological mechanisms, and treatment approaches. The 141K ABCG2 urate-increasing variant causes instability in the nucleotide-binding domain, leading to decreased surface expression and function...

The pathogenesis of hyperuricemia-induced chronic kidney disease is largely unknown. In this study, we investigated whether extracellular signal-regulated kinases1/2 (ERK1/2) would contribute to the development of hyperuricemic nephropathy (HN). In a rat model of HN induced by feeding mixture of adenine and potassium oxonate, increased ERK1/2 phosphorylation and severe glomerular sclerosis and renal interstitial fibrosis were evident, in parallel with diminished levels of renal function and increased urine microalbumin excretion...

Obesity, a risk factor for de novo chronic kidney disease (CKD), confers survival advantages in advanced CKD. This so-called obesity paradox is the archetype of the reverse epidemiology of cardiovascular risks, in addition to the lipid, blood pressure, adiponectin, homocysteine, and uric acid paradoxes. These paradoxical phenomena are in sharp contradistinction to the known epidemiology of cardiovascular risks in the general population. In addition to advanced CKD, the obesity paradox has also been observed in heart failure, chronic obstructive lung disease, liver cirrhosis, and metastatic cancer, as well as in the elderly...

AIMS: Variability in HbA1c and blood pressure (BP) is associated with the risk of diabetic kidney disease (DKD). No evidence exists on the role of variability in lipids or serum uric acid (UA), or the interplay between the variability of different parameters, on renal outcomes. MATERIALS AND METHODS: Within the AMD Annals database we identified patients with ≥5 measurements of HbA1c, SBP and DBP, total-, HDL- and LDL- cholesterol, triglycerides, and UA. Patients were followed-up for up to 5 years...

BACKGROUND AND AIMS: Metabolic Syndrome (Mets) and increased serum uric acid (SUA), are well known renal risk predictors and often coexist in patients with type 2 diabetes (T2D). Whether they independently contribute to the onset of CKD is at present unclear. METHODS AND RESULTS: Within the AMD Annals database we identified patients with T2D and normal renal function and urine albumin excretion at baseline and regular follow-up visits during a 4-year period. Blood pressure, BMI, HDL, triglycerides, and SUA were available in 14,267 patients...

There is a direct relationship between fructose intake and serum levels of uric acid (UA), which is the final product of purine metabolism. Recent preclinical and clinical evidence suggests that chronic hyperuricemia is an independent risk factor for hypertension, metabolic syndrome, and cardiovascular disease. It is probably also an independent risk factor for chronic kidney disease, Type 2 diabetes, and cognitive decline. These relationships have been observed for high serum UA levels (>5.5 mg/dL in women and >6 mg/dL in men), but also for normal to high serum UA levels (5-6 mg/dL)...

Uric acid (UA) has been associated with renal fibrosis and progression of chronic kidney disease. However, the underlying mechanisms of this process have still not been identified. Here, we studied the role of the innate imunity receptor NLRP3/ASC in UA induced epithelial-mesenchymal transition (EMT) in kidney. Wistar rats were fed with oxonic acid 2% and UA 2% (OXA + U), OXA + U plus allopurinol (ALL) or regular chow (C) for 7 weeks. We analyzed the presence of EMT markers, the expression of NLRP3, ASC, Caspase-1 and Smad 2/3 molecules and the mitochondrial morphological and functional characteristics...

Carotid-femoral pulse wave velocity (cfPWV) is a measure of arterial stiffness associated with cardiovascular events in the general population and in adults with chronic kidney disease. However, few data exist regarding cfPWV in children with chronic kidney disease. We compared observed cfPWV assessed via applanation tonometry in children enrolled in the CKiD cohort study (Chronic Kidney Disease in Children) to normative data in healthy children and examined risk factors associated with elevated cfPWV. cfPWV Z score for height/gender and age/gender was calculated from and compared with published pediatric norms...

The global burden of kidney disease is increasing strikingly in parallel with increases in obesity and diabetes. Indeed, chronic kidney disease (CKD) and end-stage renal disease (ESRD) coupled with comorbidities such as obesity, diabetes, and hypertension cost the health care system hundreds of billions of dollars in the US alone. The progression to ESRD in patients with obesity and diabetes continues despite widespread use of inhibitors of the renin-angiotensin-aldosterone system (RAAS) along with aggressive blood pressure and glycemic control in these high-risk populations...
