High Glycated Albumin and Mortality in Persons with Diabetes Mellitus on Hemodialysis.

Background: Monitoring of glycemic control with hemoglobin A (A1c) in hemodialysis patients may be compromised by anemia and erythropoietin therapy. Glycated albumin (GA) is an alternative measure of glycemic control but is not commonly used because of insufficient evidence of association to clinical outcomes. We tested whether GA measurements were associated with mortality in hemodialysis patients with diabetes mellitus.

24,25-Dihydroxyvitamin d3 and vitamin D status of community-dwelling black and white Americans.

Background: 24,25-Dihydroxyvitamin D [24,25(OH)2D] is a metabolite of 25-hydroxyvitamin D (25D). Blacks frequently have low total 25D without manifestations of vitamin D deficiency, suggesting that total serum 25D may incorrectly reflect vitamin D status in different racial groups. The ratio of serum 24,25(OH)2D to 25D [vitamin D metabolite ratio (VMR)] represents a new candidate biomarker for vitamin D status.

Protein carbamylation is associated with heart failure and mortality in diabetic patients with end-stage renal disease.

Serum carbamylated albumin (C-Alb) levels are associated with excess mortality in patients with diabetic end-stage renal disease. To gain insight into the pathophysiology of carbamylation, we determined associations between C-Alb and causes of death in patients on chronic hemodialysis. The Die Deutsche Diabetes Dialyse Studie (4D study) was a randomized controlled trial testing the effects of atorvastatin on survival in diabetic patients on dialysis during a median follow-up of 4 years.
