[Treatment of vitamin D deficiency in the general population and in patients with chronic kidney disease]

Abstract

Vitamin D is an essential micronutrient for humans. Vitamin D functions are not limited to the regulation of bone; it plays many pleiotropic effects due to ubiquitous distribution of VDR (Vitamin D Receptor). The vitamin D deficiency (defined as plasma levels of 25 - OH - vitamin D < 30 ng / ml) is now a public health problem worldwide. It is therefore essential to define protocols for supplementation of vitamin D in the general population and in patients with Chronic Kidney Disease and indications on the use of different Vitamins D available.
