OBJECTIVE: As uncontrolled hyperuricemia has been associated with an increased risk of cardiovascular disease and the progression of chronic kidney disease (CKD), management of serum uric acid levels is important. The aim of this study was to evaluate the effectiveness of febuxostat in regulating uncontrolled hyperuricemia in patients with renal dysfunction. MATERIALS AND METHODS: We included patients with CKD and persistent uncontrolled hyperuricemia despite treatment with allopurinol...

BACKGROUND: Febuxostat is tolerable in chronic kidney disease (CKD) patients with hyperuricemia. However, the long-term effect of lowering uric acid with febuxostat on renal function and blood pressure has not been elucidated. METHODS: This was a 2 years retrospective observational study. 86 CKD patients with hyperuricemia who continued with allopurinol (allopurinol group, n = 30), switched from allopurinol to febuxostat (switched group, n = 25), or were newly prescribed febuxostat (febuxostat group, n = 31) were included in this study...

OBJECTIVES: Whether uric acid levels were associated with the progression of chronic kidney disease (CKD) remained controversial. This meta-analysis was aimed to assess the effect of lowering serum uric acid therapy on the progression of CKD to clarify the role of uric acid in the progression of CKD indirectly. METHODS: Pubmed, Embase, the Cochrane library, CBM were searched for randomized controlled trials (RCTs) that assessed the efficiency of lowering serum uric acid therapy on the progression of CKD without language restriction...

PURPOSE OF REVIEW: Sodium-glucose co-transporter 2 (SGLT-2) inhibitors have emerged as a promising drug class for the treatment of diabetic kidney disease. Developed originally as glucose-lowering drugs by enhancing urinary glucose excretion, these drugs also lower many other renal and cardiovascular risk factors such as body weight, blood pressure, albuminuria, and uric acid. Results from the EMPA-REG OUTCOME and CANVAS trials show that these salutary effects translate into a reduction in cardiovascular outcomes and have the potential to delay the progression of kidney function decline...

Chronic kidney disease (CKD) is a very common condition and its prevalence is increasing worldwide. The CARHES study in Italy showed a prevalence of 6.5% in women and 7.5% in men. As a matter of fact, an early diagnosis is essential to slow down the progression and improve the renal and cardiovascular prognosis. For this purpose the A.N.Di.P. association (National Association of Peritoneal Dialysis-Onlus "Enzo Siciliano ") organized the DAY OF PREVENTION OF RENAL DISEASES which was held in AMATRICE the 15th of July 2017 called "WE START A NEW PATH OF LIFE TOGETHER"...

BACKGROUND: Hyperuricemia is a leading risk factor for the development of chronic kidney disease (CKD). We hypothesized that lowering serum uric acid (SUA) with allopurinol in hyperuricemic children with CKD may reduce the risk of CKD progression. METHODS: A total of 70 children, aged 3-15 years, with elevated serum uric acid level (SUA) > 5.5 mg/dL and CKD stages 1-3 were prospectively randomized to receive allopurinol 5 mg/kg/day (study group, n = 38) or no treatment (control group, n = 32) for 4 months...

Recent studies suggest that NLRP3 inflammasome activation is involved in the pathogenesis of chronic kidney disease (CKD). Allopurinol (ALLO) inhibits xanthine oxidase (XOD) activity, and, consequently, reduces the production of uric acid (UA) and reactive oxygen species (ROS), both of which can activate the NLRP3 pathway. Thus, ALLO can contribute to slow the progression of CKD. We investigated whether inhibition of XOD by ALLO reduces NLRP3 activation and renal injury in the 5/6 renal ablation (Nx) model...

REVIEW
Ambreen Gul, Philip Zager
PURPOSE OF REVIEW: Multiple experimental and clinical studies have identified pathways by which uric acid may facilitate the development and progression of chronic kidney disease (CKD) in people with diabetes. However, it remains uncertain if the association of uric acid with CKD represents a pathogenic effect or merely reflects renal impairment. RECENT FINDINGS: In contrast to many published reports, a recent Mendelian randomization study did not identify a causal link between uric acid and CKD in people with type 1 diabetes...

Uric acid has been known since long ago for its implication in gout and in certain kinds of nephrolithiasis. However, its role in models of acute and chronic nephropathies has been the focus of many new developments. The so called Mesoamerican nephropathy is a devastating disease that has caused more than 20'000 deaths in central America these last few years among sugarcane workers. Acid uric could play a key role in its physiopathology. Moreover, acid uric tends to be recognized as an independent factor of development and progression in chronic kidney disease, opening a way for new therapeutic targets...

BACKGROUND: Albuminuria, elevated serum creatinine and low estimated glomerular filtration rate (eGFR) are pivotal indicators of kidney decline. Yet, it is uncertain if these and emerging biomarkers such as uric acid represent independent predictors of kidney disease progression or subsequent outcomes among individuals with type 2 diabetes mellitus (T2DM). This study systematically examined the available literature documenting the role of albuminuria, serum creatinine, eGFR, and uric acid in predicting kidney disease progression and cardio-renal outcomes in persons with T2DM...

OBJECTIVE: To investigate the relationships between blood uric acid (BUA) level and the incidence, progression and deterioration of diabetic nephropathy (DN) in patients with type 2 diabetes mellitus (T2DM). PATIENTS AND METHODS: A total of fifty patients with T2DM alone whose glycosylated hemoglobin (HbA1c) were under normal range (4-6.5%) at their admission to our hospital were randomly selected as diabetes mellitus (DM) group. Fifty patients with hyperuricemia alone were randomly selected as hyperuricemia (HUA) group...

Diabetic nephropathy (DN) is one of the complications of diabetes and is now the most common cause of end-stage renal disease. Fructose is a simple carbohydrate that is present in fruits and honey and is used as a sweetener because of its sweet taste. Fructose has been reported to have the potential to progress diabetes and DN in humans even though fructose itself does not increase postprandial plasma glucose levels. In this study, we investigated the effects of high fructose intake on the kidney of the Spontaneously Diabetic Torii (SDT) rats which have renal lesions similar to those in DN patients and compared these with the effects in normal SD rats...

BACKGROUND: Diabetic nephropathy is a crucial microvascular complication of diabetes mellitus that is associated with elevated cardiovascular risk. SGLT-2 inhibitors are a new class of hypoglycemic drugs that positively affect several risk factors of cardiorenal damage. OBJECTIVES: To review and critically discuss available data on the association of SGLT-2 inhibitors treatment with kidney function, progress of diabetic kidney disease, and renal related outcomes, as well to unveil potential mechanisms of action that mediate such effects...

Chronic kidney disease (CKD) is an increasing global health burden. Disturbance in purine metabolism pathway and a higher level of serum uric acid, called hyperuricemia, is a risk factor of CKD, and it has been linked to increased prevalence and progression of the disease. In a recent study, it has been demonstrated that purine nucleotides and uric acid alter the activity of acetylcholinesterase (AChE). Thus, we hypothesize that adenine, hypoxanthine, xanthine, 2,8-dihydroxyadenine and uric acid may potentially interfere with the activity of AChE...

BACKGROUND: Diabetic nephropathy (DN) is the leading cause of end-stage renal disease (ESRD) in the western world. Current treatment methods, with better control of glycemia and blood pressure, including renin-angiotensin system blockade (RASB), appear to have slowed the DN progression rate but have not substantially decreased the annual incidence of new DN ESRD cases. Thus, new treatment targets are needed. SUMMARY: Higher levels of serum uric acid (UA) are associated with increased risk of the clinical manifestations of DN in persons with types 1 and 2 diabetes...

BACKGROUND: Chronic kidney disease (CKD) is a risk factor of cardiovascular disease (CVD) and end-stage renal disease (ESRD). Early detection and management of risk factors of incidence and progression of CKD are necessary. We have been studying these risk factors among community-based screening participants in Okinawa, Japan. Okinawa was one of the longevity areas in the world; however, the incidence and prevalence of ESRD increased. In Japan, the incidence of ESRD is 2 times higher in men compared to that in women...

Hyperuricemia may be a major contributor to the development or progression of chronic kidney disease (CKD). Although there is no clear cutoff uric acid (UA) value associated to the risk for kidney damage, it appears to be an increased risk as UA rises. Lifestyle interventions such as exercise, weight reduction, low consumption of purine-rich meat, or avoiding high fructose intake are recommended for all hyperuricemic patients. Lowering urate drugs such as allopurinol or febuxostat may be an option as a renoprotective agent; yet, randomized clinical trials evaluating the safety and efficacy of these drugs are limited to a small number of single-center studies...

Uric acid (UA) remains a risk factor for the progression of chronic kidney disease (CKD). Most observational studies showed a slight elevation in the serum UA level and this independently predicts the incidence and development of CKD. The recent meta-analysis, however, did not reach the conclusion that urate-lowering therapy with allopurinol retards the progression of CKD. The target level of serum UA if treated is another issue of debate. Our recent analysis by propensity score analysis has shown that the serum UA should be targeted below 6...

BACKGROUND: Although the clinical implication of hyperuricemia in chronic kidney disease has been an issue of active debate, recent data suggested a causative role of uric acid (UA) in the development of renal disease. Afferent arteriopathy, an induction of oxidative stress and an activation of local inflammation, have been regarded as the mechanisms of UA-induced renal disease, which contribute to glomerular hypertrophy and interstitial fibrosis via endothelial dysfunction. However, there have been rare studies on the direct effect of UA on phenotype transition of renal cells such as epithelial-to-mesenchymal transition (EMT) or endothelial-to-mesenchymal transition (EndoMT)...
