BACKGROUND AND OBJECTIVES Serum alkaline phosphatase has been associated with increased mortality in hemodialysis patients but its associations with mortality in chronic kidney disease (CKD) stages III and IV are unknown. Design, settings, participants & measurements: In 1094 participants in the African-American Study of Kidney Disease and Hypertension(More)
BACKGROUND Low serum bicarbonate concentration is a risk factor for death in people with chronic kidney disease (CKD). Whether low serum bicarbonate is a mortality risk factor for people without CKD is unknown. METHODS National Health and Nutrition Examination Survey III (NHANES III) adult participants were categorized into one of four serum bicarbonate(More)
BACKGROUND The role of traditional risk factors, including plasma lipids, in the pathogenesis of cardiovascular (CV) disease in chronic dialysis patients is unclear. Previous studies have suggested that lower serum total cholesterol (TC) is associated with higher mortality in patients on chronic haemodialysis (HD). Whether this relationship is specific to(More)
Visit-to-visit blood pressure variability (VTV-BPV) is an independent risk factor for cardiovascular events and death in the general population. We sought to determine the association of VTV-BPV with outcomes in patients on hemodialysis, using data from a National Institutes of Health-sponsored randomized trial (the HEMO study). We used the coefficient of(More)
BACKGROUND Increases in plasma anaphylatoxins frequently are used as an index of haemodialysis membrane biocompatibility; however, their plasma levels may be influenced by the loss of anaphylatoxins into the dialysate compartment. METHODS We compared the generation and compartmental distribution of anaphylatoxins, C3a and C5a, in a high flux and a low(More)
Established as a method to study anatomic changes, such as renal tumors or atherosclerotic vascular disease, magnetic resonance imaging (MRI) to interrogate renal function has only recently begun to come of age. In this review, we briefly introduce some of the most important MRI techniques for renal functional imaging, and then review current findings on(More)
Adiponectin is a multifunctional adipokine with insulin-sensitizing, anti-inflammatory, and vasoprotective properties. Epidemiology studies have, however, shown that high levels of serum adiponectin are associated with kidney disease progression. We, therefore, examined the effect of adiponectin administration on the progression of glomerulosclerosis in the(More)
BACKGROUND There is no evidence from randomized trials to support a strategy of lowering systolic blood pressure below 135 to 140 mm Hg in persons with type 2 diabetes mellitus. We investigated whether therapy targeting normal systolic pressure (i.e., <120 mm Hg) reduces major cardiovascular events in participants with type 2 diabetes at high risk for(More)
BACKGROUND The relationship between blood pressure (BP) and mortality in haemodialysis patients is unconventional. It is not clear if this is the consequence of uraemia or related to the dialysis type. The goal of this project was to identify the relationship between BP and mortality in patients on chronic peritoneal dialysis (PD). METHODS Patients on PD(More)
