Effect of Multivitamin Supplements on Clinical and Immunological Response in Childhood Tuberculosis

March 28, 2015 updated by: Wafaie Fawzi, Harvard School of Public Health (HSPH)
The purpose of this study is to see whether children who take vitamins along with the standard medicine for tuberculosis (TB) recover better and quicker than children who take only the standard medicine for TB. Four hundred children ages 6 weeks-5 years, who have been diagnosed with tuberculosis, will be enrolled. They will be followed for 2 months after treatment for TB. Study procedures may include blood draws, Tuberculin Skin Tests, body measurements, gastric aspirates (removal of stomach fluid), physical exams, and questionnaires. This study will occur in Tanzania.

Study Overview

Detailed Description

Tuberculosis (TB) remains the single most common infectious disease cause of mortality worldwide with evidence that support nutritional status may be associated with poor outcomes in TB patients. Data from observational and limited intervention studies support the hypothesis that nutritional supplements/micronutrients may be beneficial as well as potential treatments in TB. The effect of micronutrient status will be examined in the context of a double blinded placebo controlled randomized trial; 400 tuberculosis patients (age 6 weeks to 5 years) will be randomized to receive either multi-micronutrients or placebo from the start of their anti-TB therapy, through 2 months of their anti-TB therapy. The primary objective is to evaluate the efficacy of a multivitamin supplement containing vitamins B, C and E on weight gain in childhood tuberculosis at 2 months after start of anti-tuberculosis therapy. Secondary objectives are to: evaluate the efficacy of a multivitamin supplement containing vitamins B, C, and E on clearance of chest x-ray in childhood tuberculosis at 2 months after start of anti-tuberculosis therapy; compare the treatment arms with respect to the following immunological parameters: ex-vivo lymphocyte proliferation; cytokines production including IL-2, IL-12, TNF - alpha, INF-gamma; and CD4 and CD8 T-lymphocyte counts at 2 months after start of anti-tuberculosis therapy; assess the validity of Tuberculin Skin Test (TST) for the diagnosis of childhood tuberculosis in a population with high BCG coverage and HIV prevalence; assess the validity and feasibility of using "microscopic observation broth drug susceptibility (MODS) assay" of sputum and gastric aspirates in the diagnosis of childhood tuberculosis; correlate the above-mentioned immunological markers (IL-2, IL-12, INF-gamma and TNF-alpha) with weight gain and chest x-ray at 2 months after start of anti-tuberculosis therapy; and compare the immunological response to a supplement containing vitamins B, C and E in childhood tuberculosis patients with and without HIV infection. The endpoints of interest include immunological parameters like CD4 T lymphocyte count and clinical outcomes such as, weight gain and resolution of chest x-ray after 2 months anti-TB therapy. Researchers will also examine the utility of these immune response parameters as surrogate markers for treatment efficacy in TB, irrespective of nutritional and other risk factors.
