This objective of this study was to determine benefit of one month combined supplementation (zinc, vitamin A, fish oil) along with anti-tuberculosis drugs (ATD) on increasing serum leptin levels and decreasing tumor necrosis factor-alpha (TNF-alpha) in children with tuberculosis (TB). A quasi experimental study was conducted on 22 children (aged 5-14 years) with a positive acid-fast bacilli (AFB) smear. The children were divided into 2 groups. A history, physical examination, anthropometric measurements, serum leptin levels, TNF-alpha levels, retinol and zinc levels were examined in all subjects before and after treatment. Nutritional supplementation and ATD were given to group I while ATD only were given to group II. The change in leptin, TNF-alpha, retinol and zinc levels were analyzed with the Mann-Whitney test, while a t-test was used to determine changes in body mass index (BMI). Group I had a higher significant increase in serum leptin levels than group II (p=0.034). Group I had a significantly greater decrease in TNF-a levels than group II (p=0.032). No significant differences in retinol or zinc levels were seen between the two, but both groups had an increase after treatment. Both groups had a significant increase in BMI (p=<0.001) post-treatment compared to pre-treatment. Supplementation with zinc, vitamin A and fish oil is associated with a significant increase in leptin levels and a significant decrease in TNF-alpha levels among children treated for TB. No significant benefit was seen in BMI among children receiving supplementation compared to those without it, although ATD resulted in a significant increase in BMI in both groups.
