The study aimed to evaluate the influence of mutation gene rpoB of Mycobacterium (M.) tuberculosis cluster I (507-534) on the elimination of 25-Desacetyl Rifampicin (25-DR) in the urine of tuberculosis (TB) subjects. Early morning sputum took from patient TB before treatment. Urine collected after 2 hours taken Fixed-Dose Combination (FDC) at days 7th treatment. All sputum were sequencing at Macrogen Korea Laboratory. Urine was analyzed by high-Performance Liquid Chromatography (HPLC) using the method of Lily et al. Mean (standard deviation) for mutation and non-mutation of rpoB M. tuberculosis group were 7.6147 (4.4478) and 4.5772 (1.7532) μg/ml, respectively. Shapiro-Wilk test showed normally distributed data, with significance 0.3. Independent t-test performed p-value 0.167 and confidence interval (CI) from -1.648 to 7.723. The mutation gene rpoB of M. tuberculosis cluster, I (507-534) in this study, did not affect elimination 25-DR in theurine of TB subjects statistically and clinically.
