There is a high prevalence of hyperuricemia (HUA) in the chronic kidney disease (CKD) population. However, there's a dearth of research on HUA's prevalence, subtypes, early detection, and treatment strategies of HUA in lupus nephritis (LN) patients. The aim of this study is to address these knowledge gaps. LN patients presenting to the Department of Nephrology at Shanghai Rui Jin Hospital from January 2011 to January 2016 were recruited. The effective sample size was derived using the power analysis. The demographic, clinical and laboratory characteristics of the LN patients with HUA were compared with those of patients without HUA...

BACKGROUND: Elevated uric acid concentration is associated with higher rates of cardiovascular (CV) morbidity and mortality in the general population. It is not known whether hyperuricemia increases the risk for CV death or transplant failure in kidney transplant recipients. STUDY DESIGN: Post hoc cohort analysis of the FAVORIT Study, a randomized controlled trial that examined the effect of homocysteine-lowering vitamins on CV disease in kidney transplantation...

Acute kidney injury causes great morbidity and mortality in both the community and hospital settings. Understanding the etiological factors and the pathophysiological principles resulting in acute kidney injury is essential in prompting appropriate therapies. Recently hyperuricemia has been recognized as a potentially modifiable risk factor for acute kidney injury, including that associated with cardiovascular surgery, radiocontrast administration, rhabdomyolysis, and associated with heat stress. This review discussed the evidence that repeated episodes of acute kidney injury from heat stress and dehydration may also underlie the pathogenesis of the chronic kidney disease epidemic that is occurring in Central America (Mesoamerican nephropathy)...

The association between uric acid (UA) on one side and systemic hypertension (Htn), dyslipidemia, glucose intolerance, overweight, fatty liver, renal disease and cardiovascular disease (CVD) on the other side is well recognized. However, the causal relationship between UA and these different clinical problems is still debatable. The recent years have witnessed hundreds of experimental and clinical trials that favored the opinion that UA is a probable player in the pathogenesis of these disease entities. These studies disclosed the strong association between hyperuricemia and metabolic syndrome (MS), obesity, Htn, type 2 diabetes mellitus (DM), non-alcoholic fatty liver disease, hypertriglyceridemia, acute kidney injury, chronic kidney disease (CKD), coronary heart disease (CHD), heart failure and increased mortality among cardiac and CKD patients...

Uric acid is a product of purine catabolism formed by the activity of xanthine-oxidase and prevalently excreted by the kidney. In vivo, urate is known to have both an anti- or pro-oxidant role depending on several biological conditions. New evidence suggests that chronic hyperuricemia can contribute to hypertension development, kidney disease and cardiovascular risk. The pathophysiologic mechanisms are various, such as endothelial dysfunction and oxidative stress, vasoconstriction and stimulation of renin angiotensin system...

Accumulating data indicate that renal uric acid (UA) handling is altered in diabetes and by hypoglycemic agents. In addition, hyperinsulinemia is associated with hyperuricemia and hypouricosuria. However, the underlying mechanisms remain unclear. In this study, we aimed to investigate how diabetes and hypoglycemic agents alter the levels of renal UA transporters. In insulin-depleted diabetic rats with streptozotocin treatment, both UA excretion and fractional excretion of UA (FEUA) were increased, suggesting that tubular handling of UA is altered in this model...

Gout is the most common form of inflammatory arthropathy and is caused by an excess of uric acid in the blood (hyperuricemia). It is a chronic, debilitating condition that gradually increases in severity and affects an increasing number of people. It has a wide spectrum of clinical manifestations and is related to serious kidney and cardiovascular conditions and to an increased risk of mortality. The negative perception of the disease, historically seen as related to a life of dissipation, has led to underestimating its impact and focusing the attention on the short-term treatment of acute attacks rather than on the long-term management of the condition without, consequently, preventing the most serious complications...

Rheumatoid arthritis (RA) is associated with increased cardiovascular disease (CVD) mortality and morbidity, due to the combined effects of traditional and non-traditional cardiovascular risk factors (CV). A serum uric acid (SUA) level has been suggested as one of the non-traditional cardiovascular risk factors. Cardiovascular risk can be assessed by looking at the subclinical atherosclerosis such as ultrasound (US)-measured carotid intima-media thickness (cIMT). This paper aimed to determine the role of SUA as a cardiovascular risk factor, along with the traditional cardiovascular risk factors and inflammation, among RA population...

PURPOSE: Chronic kidney disease is a major public health concern. Serum uric acid (SUA) at high levels was oxidative stress agents, and total bilirubin (T-BiL) at mildly increased levels was potent antioxidants, but whether SUA and T-BiL produce an additive interaction for the risk of renal dysfunction remains unclear. METHODS: The subjects comprised 567 men aged 71 ± 8 (mean ± standard deviation) years and 853 women aged 70 ± 8 years from a rural village...

For the last few years, the role of uric acid in the pathogenesis of the hypertension and chronic kidney disease has drawn attention due to the increasing prevalence of the aforementioned states. Uric acid (UA), formed as a result of purine metabolism, is subject in the renal proximal tubule to filtration, reabsorption and secretion. The mechanisms of deleterious effect of UA on the kidney involve endothelial damage and the increment of hydrostatic pressure in the glomerulus which in turn lead to hypertrophy and glomerulosclerosis...

BACKGROUND: Gout, hyperuricemia, and cardiovascular disease (CVD) are prevalent conditions in the United States, and while they share common risk factors such as obesity, hypertension, hypercholesterolemia, and type 2 diabetes mellitus, relatively little is known about what patient and disease characteristics may link CVD with hyperuricemia and gout and how the presence of both diseases affects management decisions differently than for patients with gout alone. OBJECTIVE: To identify differences in patient characteristics, patterns of urate-lowering therapy (ULT) use, and gout control in gout patients with and without cardiovascular comorbidity...

INTRODUCTION: Uric acid (UA), a breakdown product of purines, has been associated with mortality in different populations. Less is known about associations between hyperuricemia and mortality in chronic kidney disease (CKD) patients, later undergoing hemodialysis (HD), during a long observation period. The aim of this study was to determine the impact of elevated UA levels on long-term (19.5 years) survival of CKD patients. METHODS: 120 CKD patients (49 female, 71 male) enrolled in our study were observed from their first visit at the patients' nephrology outpatient clinic (NOC)...

BACKGROUND: Hyperuricemia has been associated with kidney disease and remains controversial with regard to its gender-specific differences and impact in living kidney donation. METHODS: Between 2006 and 2015, charts of live kidney donors who underwent nephrectomy and had a minimum follow-up of 1 year were reviewed. A total of 291 donors were included and divided based on gender-specific pre-donation serum uric acid (SUA) tertiles. Renal functional outcomes included were estimated glomerular filtration rate (eGFR) at 6-month and 1-year follow-up and percentage of donors with a 1-year eGFR <60 mL/min/1...
