Vitamin D as a novel nontraditional risk factor for mortality in hemodialysis patients: The need for randomized trials

Vitamin D has been used in the context of secondary hyperparathyroidism in patients with end-stage renal disease. A wave of recent studies suggests that vitamin D treatment may be associated with decreased mortality risk in these patients. The article by Wolf et al. further supports these studies by identifying vitamin D deficiency as a risk factor for early mortality in incident hemodialysis patients.
