RESULTS: There were 40 subjects diagnosed with pulmonary tuberculosis who participated the study. Twenty-three were male (57.5%) and 17 were female (42.5%). The age ranges from 1 to 18 years with a mean age of 8.6 + 5.5. Out of the 40 participants, 32 had completed the study. In this study, the analysis of data showed that the level of serum hsCRP after the intensive phase of treatment is significantly lower compared to the level before treatment (p value of 0.0002). On the other hand, body mass index (BMI), which is being used as one of the objective parameters of treatment response in children, demonstrated a statistically significant difference before and after the intensive phase at a p value of 0.0007. High sensitivity C-reactive protein and BMI were indirectly correlated, however, it was statistically insignificant before and after 2 months of treatment at p value of 0.26 and 0.35, respectively.
