Outcome Measures
Primary Outcomes (1)
To determine the efficacy of micronutrient supplements on sputum conversion, survival, and TB relapse and reinfection.
Sputum and culture negativity: 1 month and 2 months; Survival: 8 months and 24 months; TB relapse and reinfection: throughout follow-up.
Secondary Outcomes (1)
To examine the effect of micronutrient supplements on HIV viral load, CD4 counts, body weight and immunological parameters.
Rate of change of HIV viral load in HIV positive patients: 2, 5, 8, and 20 months; Absolute change in CD4 counts: 2, 5, 8, and 20 months; Weight change from baseline: 2, 8, and 20 months; Immunological parameters: 2, 8, and 20 months.
