Vitamin D in Klinik und Praxis

Abstract

Vitamin D is unique among the vitamins, since its major source is skin synthesis by solar UVB exposure, whereas dietary intake plays only a minor role. In the general population, cutaneous vitamin D synthesis is clearly below the recommended amount. Dietary vitamin D does not fill this gap. Severe vitamin D deficiency results in rickets in infants and osteomalacia in adults. In the absence of endogenous vitamin D synthesis (e. g. during winter), oral supplements should ensure adequate daily vitamin D intake, where appropriate. This is particularly true for nursing home residents, non-European migrants and dark-skinned people.

Vitamin-D-Mangel und seine Konsequenzen – seit Jahren schon ein sehr präsentes Thema. Nicht zu Unrecht: In der Allgemeinbevölkerung verfehlt die kutane Vitamin-D-Synthese besonders im Winter deutlich die Zufuhrempfehlung. Klar ist, aufgrund der vielfältigen Wirkungen wird Vitamin D auch in Zukunft weiter an Bedeutung gewinnen. Der CME-Beitrag hilft Ihnen, in der Informationsflut die Relevanz des Themas für Klinik und Praxis zu bewahren.
