Clinical Trial 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.

Clinical Trial Description

This study consist of 2 designs. First is in vitro study to investigate the effect of alfacalcidol supplementation to IL-6, IL-10 and IFN gamma regulation in Peripheral Blood Mononuclear Cells (PBMC) of elderly and second design is randomised controlled trial to evaluate the effect of 3 months supplementation of alfacalcidol 0,5 mcg in respiratory infection, antibiotic use, inflammatory markers, CD4/CD8 ratio and CD8+ CD28+ in Indonesian elderly with various level of frailty syndrome. ;
