Impact on UVB Narrow Band and UVA1 Therapy on Serum 25-hydroxyvitamin D Levels

Summary

We plan to investigate the serum elevation of 25(OH)D under UVB nb and UVA1 therapy, in order to determine the effect of these nowadays frequently used wavelengths for phototherapy on vitamin D plasma levels. We hope for a better understanding of steady-state and treatment-induced levels of vitamin D changes to better recognize the impact of phototherapy on vitamin D synthesis in the skin, the dimension of vitamin D production to be expected in the course of standard phototherapy and a potential gap in vitamin D production compared to physiological needs which then should be supplemented orally.
