  Purpose

Vitamin D has been regarded to be beneficial to tuberculosis (TB) patients. The aim of this study is to elucidate the role of vitamin D deficiency in development and treatment outcomes among Korean TB patients. Furthermore, the impact of genotypes of vitamin D receptor gene on TB development will also be evaluated.
