This is an interventional treatment trial for Multidrug Resistant Tuberculosis focused on measuring Multidrug Resistant Tuberculosis, Pyrazinamide
Eligibility Criteria
Inclusion Criteria:
- Patients who are diagnosed with active tuberculosis
- Patients who are smear positive and sputum culture positive for tuberculosis
- History of active tuberculosis less than 3 years
- With less than 2 times of previous antituberculous therapy
- The patients should be voluntarily entering the study and willing to sign up the consent form after full knowledge of the risks, schedule, drug features of this study.
- MDR-TB is defined as resistance to the following two drugs: Isoniazid and Rifampicin.
