Predictors of Vitamin D Status in Predialysis Chronic Kidney Disease Patients: A Cross-sectional Analysis in a High Ultraviolet Climate
Journal of Renal Nutrition, 07/11/2012
Petchey WG et al. – 25–hydroxyvitamin D (25–OHD) insufficiency is mitigated but still highly prevalent in patients with chronic kidney disease (CKD) in a high ambient ultraviolet environment. Despite the maintenance of relatively higher 25–OHD concentrations with advancing CKD, substrate availability does not appear to be a major determinant of circulating 1,25–OHD.
