NCT03008057

Brief Summary

The aim of this study is to determine the effects of vitamin D or placebo for 3 months on the gene expression of glyoxalase enzyme, RAGE, and YKL40 in the peripheral blood mononuclear cell (PBMC) and serum levels of YKL40,AGEs, TNF-α, PAI-1, IL-6, and HbA1c of diabetes type 2 patients.
