NCT02464683

Brief Summary

Tuberculosis (TB) is the second largest infectious disease that causes death in the last 4 centuries in all the world. Observational studies found an association between vitaminD and TB, suggesting a potential therapeutic role of vitaminD supplementation in patients with active tuberculosis. The hypothesis is that the administration of vitaminD is associated with changes in the levels of cytokines in patients with tuberculosis treated with first-line drugs. The aim of this study is to evaluate the effect of vitaminD supplementation on the clinical course, the time of negative smears and cultures, and the effect on the immune response in patients with pulmonary tuberculosis (TBP).

Outcome Measures

Primary Outcomes (1)

  • Determination of cytokines

    First, we are going to separate the peripheral blood mononuclear cells with Ficoll reagent. Cells were adjusted and placed in 1 mL tubes, with an antibody will be incubated for 15 min. at room temperature. Anti-antibody corresponding isotypes are going to incubate for 20 min at room temperature. The cells are going to be fixed with 1% paraformaldehyde before acquiring and analyzing in the flow cytometer. The concentration of Interleucin 17 (IL-17), Interferon-g and Tumor Necrosis Factor-a in culture supernatants of infected cells in vitro with M.tuberculosis are going to be measure. We are going to determinate them by ELISA.
