Vitamin D Deficiency Clinical Trial
Official title:
Immunologic Functions of a Single Dose of 100.000 I.U. Cholecalciferol (Vitamin D3)
Vitamin D receptors are expressed in activated different immune cells. It is not known, which immune cell type is targeted by exogenous vitamin D. Here, vitamin D-deficient individuals will receive once 100.000 I.U. vitamin D3 either intramuscular or subcutaneous in a double-blind placebo controlled setting. Immune cells will be monitored from the blood over time.
Vitamin D-deficient individuals will receive once
- double-blind, placebo controlled 100.000 I.U.vitamin D3
- intramuscular or subcutaneous
Blood will be taken over time and
- immune cells (T cells, B cells, myeloid antigen presenting cells) are characterized by
flow-cytometry
- vitamin D-metabolites will be monitored
