BACKGROUND Hyperuricemia is prevalent in patients with chronic kidney disease (CKD); however, data are limited about the relationship of uric acid levels with long-term outcomes in this patient population. STUDY DESIGN Cohort study. SETTING & PARTICIPANTS The Modification of Diet in Renal Disease (MDRD) Study was a randomized controlled trial (N = 840)(More)
Adiponectin is presumed to possess antiatherogenic and cardioprotective properties. Limited data exist on the relationship between adiponectin and mortality in the earlier stages of chronic kidney disease. The Modification of Diet in Renal Disease study was a randomized, controlled trial that was conducted between 1989 and 1993. Adiponectin was measured in(More)
Chronic kidney disease (CKD) is a growing public health problem. The incidence of kidney failure is rising in all age groups but particularly in older adults. Individuals in all stages of CKD are at higher risk for development of cognitive impairment and this may be a major determinant in their quality of life. Furthermore, cognitive impairment is(More)
One of the proposed causes of obesity and metabolic syndrome is the excessive intake of products containing added sugars, in particular, fructose. Although the ability of excessive intake of fructose to induce metabolic syndrome is mounting, to date, no study has addressed whether a diet specifically lowering fructose but not total carbohydrates can reduce(More)
PURPOSE OF REVIEW To discuss recent studies which have evaluated determinants of cystatin C and to focus on the relationship of cystatin C with mortality, cardiovascular disease (CVD), and noncardiovascular outcomes. RECENT FINDINGS In the Chronic Kidney Disease Epidemiology Study cystatin C was associated with demographic characteristics independent of(More)
PURPOSE OF THE REVIEW Acute kidney injury (AKI) and chronic kidney disease (CKD) are conditions that substantially increase morbidity and mortality. Although novel biomarkers are being used in practice, the diagnosis of AKI and CKD is still made with surrogate markers of GFR, such as serum creatinine (SCr), urine output and creatinine based estimating(More)
PURPOSE OF REVIEW Glomerular filtration rate is widely accepted as the best overall measure of kidney function. Currently available methods to estimate glomerular filtration rate have strengths and limitations. Cystatin C is a novel endogenous filtration marker being considered as a potential replacement for serum creatinine. This review summarizes the(More)
BACKGROUND Chronic kidney disease (CKD) is associated with increased risk for cardiovascular (CV) disease and is also associated with elevated uric acid, which is emerging as a nontraditional CV risk factor. We therefore evaluated uric acid as a risk factor for CV disease in subjects presenting to nephrologists with CKD who were not on medications known to(More)
Arteriolosclerosis (microvascular disease) may have a key role not only in driving salt-sensitive hypertension but also in mediating the development of chronic kidney disease, vascular dementia, stroke and coronary heart disease. In this paper, we review the evidence that these latter conditions result from the altered autoregulation that occurs when(More)
