Brief Summary
This study, conducted jointly by researchers at the National Masan TB Hospital, Asan and Samsung Medical Centers in Seoul, Republic of Korea, and the Yonsei University and the NIH in the United States, will examine why some patients with tuberculosis (TB) develop disease that is harder to treat than most cases. TB is an infection of the lung that usually can be successfully treated with anti-TB drugs. However, some people get a more serious kind of disease (called multi-drug resistant TB or extensively drug-resistant TB) that is very difficult to treat and may not be cured by the regular medicines available. This study will try to find out if some of the common TB drugs are getting to the place where the TB bacteria are. It will also look at how current anti-TB drugs might be used more effectively and how better drugs might be developed. People 20 years of age and older with hard-to-treat TB who have elected to undergo surgical removal of part of their lung at the National Masan Tuberculosis Hospital, Masan, the Asan Medical Center, and the Samsung Medical Center, may be eligible for this study. Participants undergo the following procedures:
- Medical history and physical examination, including sputum sample.
- Blood tests at various times during the study.
- Drug administration. Subjects are given one dose each of five common TB drugs rifampicin, isoniazid, pyrazinamide, kanamycin and moxifloxacin before they undergo surgery to remove part of their lung. After surgery, some of the lung tissue and fluid around the lungs that was removed during surgery will be examined to determine the regions where the TB bacteria live and analyze the lung tissue itself.
- Dynamic MRI (magnetic resonance imaging) scan. This type of scan uses a magnetic field and radio waves to produce pictures of the lung. Subjects lie very still on a table inside the cylindrical scanner with their head on a soft cradle and their hands over their head. Several images are obtained for less than 5 minutes at a time.

Interventions
Rifampicin or rifampin (RIF) is a semi-synthetic compound derived from Amycolatopsis rifamycinica. It is mostly used in combination to treat TB, while other disease indications include brucellosis, leprosy, legionnaire's disease and problematic drug-resistant staphylococcal infections. RIF inhibits DNA-dependent RNA polymerase in bacterial cells by binding its beta-subunit, thus preventing transcription to RNA. Its MIC against replicating TB bacilli is 0.1 g/ml and its minimum bactericidal activity (MBC) is 0.5 g/mL. It is one of the rare anti-TB drugs with some activity against nonreplicating cells.
Isoniazid (INH) is a first-line antituberculous medication discovered in 1952 and used in the prevention (alone) and treatment (in combination) of tuberculosis. Isoniazid is a prodrug and must be activated by a bacterial catalase to inhibit the synthesis of mycolic acids in the mycobacterial cell wall. Consequently, INH is bactericidal to rapidly-dividing mycobacteria, with an MIC of 0.05 g/ml and an MBC of 1 g/ml, but is inactive if the mycobacterium is nonreplicating or slow-growing.
Pyrazinamide (PZA) is a synthetic derivative of nicotinamide requiring ctivation by the mycobacterial enzyme pyrazinamidase, only active under acidic conditions which are thought to be found within the phagolysosomal compartment of macrophages. The conversion product, pyrazinoic acid, inhibits fatty acid synthetase I, required by the bacterium to synthesize fatty acids, though this has been disputed. It has an MIC of 6 g/ml and is not cidal under in vitro conditions. Overall, its mechanism of action and reasons for good sterilizing activity in vivo are poorly understood. It is part of the 4-drug combination recommended by the WHO to treat drugsensitive tuberculosis and is also included in most econd-line regimens.
Kanamycin (KM) is an aminoglycoside antibiotic belonging to the same class of drugs as Streptomycin, one of the first drugs used to treat TB in the 50 s. It kills sensitive bacteria by binding to the 30S ribosomal subunit and interfering with protein synthesis. Its MIC and MBC against MTB are 2 and 6 g/mL, respectively, with a remarkably low MBC/MIC ratio. However, KM is only used to treat serious bacterial infections due to severe renal toxicity and ototoxicity. No interaction with the metabolism of other drugs has been reported. The drug is approved by the Korean Ministry of Food and Drug Safety (MFDS) but not the US FDA for use against pulmonary TB.
Moxifloxacin (MXF) is a synthetic fluoroquinolone antibiotic. It inhibits bacterial topoisomerase II (DNA gyrase) and topoisomerase IV, which are essential enzymes playing a crucial role in the replication and repair of bacterial DNA. Its MIC, MBC and intracellular activity against MTB are 0.5, 2 and 1 g/mL, respectively, with again a low MBC/MIC ratio.
