Abstract:
:The biological mechanisms, ecological and observational studies indicate increased morbidity and mortality in vitamin D deficiency, while the controlled, randomized supplementation trials - carried out mostly in vitamin D deficient patients - have shown no or some marginal benefits, mostly in preventing institutionalized elderly individuals' falls and fractures. Clarity is also disturbed by that the primary end points of intervention studies were generally not extraskeletal. The ideal serum 25-hydroxyvitamin D levels also considerably controversial: there is clearly a J-curve, but the optimal range is uncertain. All of these uncertainties appear also in the vitamin D guidelines which are, however, concordant in that they do not recommend (i) a population-wide screening and (ii) vitamin D supplementation with extraskeletal aim - beyond the prevention of falls. Certain studies suggest that calcium supplementation increases the incidence of cardiovascular events, while others show a neutral effect in this respect. There are several ongoing vitamin D studies directly designed for extraskeletal events. Orv. Hetil., 2016, 157(31), 1242-1247.
