Brief Summary

Vitamin D has been known to influence immune response through Vitamin D Receptor in Immune Cells, but only few has been known about the effect alfacalcidol, a vitamin D analog to immune system. In elderly, immune disregulation or immunosenecence have great impact to infection response. This study is aimed to determine the effect of alfacalcidol supplementation in vitro and in vivo to respiratory infection incidence and inflammatory markers, as well as T cell lymphocyte subset in Indonesian elderly patients.
