Measurement of Anti-TB Drugs in Lung Tissue From Patients Having Surgery to Treat Tuberculosis

Plain-language 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.
